Alas, there is no way. [No pop-up novel website] I can only exchange it for this one. Zhan Wuya's body ached extremely. Although the high-quality Big Red Eagle is already last year's cigarette. But he carefully preserved the taste without changing at all.
This thing can accomplish a lot of things with just one flick. Now that a pack of it is being given away, Zhan Wuya is extremely distressed.
After finding Ma Qianzhu, he spent a lot of words, countless saliva and a pack of cigarettes, and finally got two bottles of refrigerant with the promise that he would try it out after the ice machine was built.
"Without p12, I won't be able to play with the angry dog anymore——"
"You can play with real iron - I will build a machine gun specifically for you in the future..." Zhan Wuya said nonchalantly and put two bottles of F12 into his bag.
After fighting all night and debugging and disassembling the equipment countless times, a large piece of white ice finally appeared in the condenser! Zhan Wuya and Liang Xin suddenly became more energetic - this thing can still work after all!
Zhan Wuya hurried back to the office to find his thermos cup, packed the first piece of ice and sent it to the Governor - with a piece of paper "Good News" attached on it, and then he went there beating gongs and drums. .
Liang Xin called the canteen and asked the canteen to quickly bring some incubators. The insulation material in this earthen insulated box is kapok and cotton, and it is specially used to transport popsicles and fresh seafood from the Fengcheng Wheel.
In the end, this ice machine can produce about 2 kilograms of ice per hour. To be honest, the efficiency is a bit low. However, Liang Xin noticed that their insulation measures were too poor, and it would be better if they improved the ice-making efficiency.
Everyone is very happy that the Work Energy Commission has come up with such a thing. After all, it is inconvenient to transport ice from Bopu. Now that there is a thing, you can enjoy frozen food anytime and anywhere. Someone immediately suggested installing one in the canteen. Some people also suggested that they simply dismantle all the air conditioners in their hands and convert them into ice machines - there are only so many air conditioners anyway, and they are not good for anyone to use. They could just dismantle them and make ice cubes for everyone to enjoy.
In fact, the call for the production of refrigeration equipment has been very high recently, not only in Ziminglou. The communications center needs ice to cool down equipment, the explosives workshop needs ice to cool down to ensure production safety, and the canteen needs to preserve food. The Ministry of Health wants to preserve cadavers for autopsy...
The number of refrigerators in the Time Travel Group is really pitiful - no one had thought of this thing in the first place. The cold storage on the Fengcheng ship is a little far away from Bairencheng, and the cold storage on the ship uses auxiliary engines to burn precious diesel to keep it running. Ma Qianzhu has always hoped that the Works Energy Commission can come up with refrigeration equipment that is more economical than marine cold storage.
The Work Energy Commission has held several meetings on this issue. They have long found a relatively simple, feasible and economical way to achieve Ma Qianzhu's request, and that is the gas refrigerator mentioned by Liang Xin.
The so-called gas refrigerator uses gas heating to boil concentrated ammonia water. The steamed ammonia vapor is cooled to condense and liquefy the water vapor in it. The ammonia gas is condensed into liquid ammonia, and then mixed with hydrogen at the entrance of the steamer. Due to the different partial pressures of ammonia, It diffuses violently from the ammonia liquid into the hydrogen, lowering the temperature of the evaporator and acting as a refrigeration agent. After that, the ammonia gas is absorbed by the dilute ammonia water and becomes a concentrated ammonia liquid, and the remaining hydrogen gas is returned to the steamer. Therefore, a gas refrigerator is heated by gas combustion, which circulates ammonia, water, and hydrogen in the pipeline to cool it. The cooling temperature can reach as low as minus 4 degrees. Extremely efficient.
Ammonia water is no longer a problem when the 800-ton ammonia synthesis system has begun initial operation. Hydrogen is a by-product obtained during the electrolysis of salt soda production process.
Using this principle, it is possible to create a small refrigerator at the level of a household refrigerator. According to the standards of the 20th century, the technical content of gas refrigerators is very low. However, in the Lingao industrial system in 1629, there were many practical problems that could not be solved in the manufacturing of miniaturized gas refrigerators. Especially the materials and workmanship. For example, the manufacturing and processing of refractory ceramics on the combustion head and the zinc alloy die-casting of the burner shell, none of these can be solved immediately. In addition, the efficient insulation materials necessary for the box are also what they lack.
Since it cannot be made too finely, the Works and Energy Commission plans to build a large "gas refrigerator" to reduce the technical difficulty of manufacturing - small refractory ceramic burners cannot be made, but large cast iron burners are always no problem - in fact They are going to build a gas cold storage.
This cold storage was first built in the canteen - the canteen itself has a sufficient supply of biogas, and now that there is coal gas, the fuel is abundant. As for insulation materials, neither kapok nor cotton can effectively preserve heat. Zhan Wuya used the most common method of ice storage in ancient times - building cold storage underground and using soil to keep the heat. In the past, several major ice cellars in Beijing were all Make ice and store ice in the twelfth lunar month. The storage conditions are earth kilns, which are covered with straw curtains and piled with soil. When the ice cellar is opened in the second summer, the loss of ice is so small that it can be ignored.
Lingao Construction Company first dug a rectangular cellar with one side open under a small slope of the farm. After compacting the ground and four walls, it was paved with porous bricks. Then add insulation material to the inner wall.
The Works and Energy Commission has neither foam nor asbestos. The only natural insulation materials that can be supplied in large quantities in Lingao are kapok and diatomaceous earth. In order to ensure the effect, the Works and Energy Commission laid multiple layers alternately on the inner wall of the cold storage. All pipes are made of brass. After the cold storage is installed, a layer of straw curtains is laid on top, and finally it is completely covered with thick soil. Only one access channel is left connected to the ground. The passage is equipped with two layers of wooden doors, both inside and outside. The door is covered with thick insulation material. The people in the machinery factory tried their best to make it as close as possible to the door frame, and attached several layers of belts as sealing materials. The combustion chamber of the cold storage is set on the ground. Use the gas from the farm's supporting gas stove for heating. It rains a lot in Lingao, so a house was built above the entire underground cold storage for shelter, with drainage ditches on all sides.
After the ignition, the cold storage ran continuously for 24 hours, which proved that the minimum cooling of this cold storage was minus 16 degrees, and it could be stably maintained at this level.
Everyone is already very satisfied with this. The minus 40 degrees that can be reached has no special significance to the crossing group. At minus 16 degrees, it is possible to store various fresh foods, make ice cubes, and produce various cold drinks for a long time.
Due to the construction of cold storage that can produce ice in large quantities cheaply, it not only meets dietary needs, but also acts as an air conditioner to a certain extent - large ice cubes taken from the cold storage are placed in the house to allow it to melt naturally. , this traditional cooling method quickly spread in the dormitories and offices of travelers. In order to prevent everyone from rushing to collect the ice, the planning committee issued ice tickets to everyone after careful calculation, in addition to the daily kilograms of ice quota for individual travelers. Each department has different quota standards based on needs.
Lingao Telecom's communication computer room has finally become cooler - not only for comfort, but also to ensure the normal operation of the machinery and equipment. Since the beginning of summer, Lingao Telecom's units, in addition to using enhanced ventilation to cool down, have adopted a method of starting up in turns to avoid accidents caused by excessive heat.
Aboriginal workers who worked in high temperatures also enjoyed the coolness of the ice cubes. This kind of treatment moved many workers very much - being able to use ice in the summer was a treat for the rich, but now it can be enjoyed by ordinary people like them. Although the air-conditioning in the huge workshop can't offset the heat. But as Xiao Zishan often said: "Sometimes the people just want the rulers to have a minimum attitude."
Due to the strong demand for ice, the Works and Energy Commission soon organized the construction of a second and third cold storage. Due to the accumulation of experience and the more skilled the construction technology, the energy consumption of the cold storage is further reduced, and the probability of failure is also greatly reduced.
With the completion of the professional fishing cold storage and supporting gas station in Bopu, the cold storage on the Fengcheng ship ceased operation under the order of the Planning Commission. After this power-consuming powerhouse stopped operating, the operation of Fengcheng's auxiliary engines was also reduced to the lowest power required to maintain the ship's own system to save fuel. After this cold storage, which had been operating continuously for nearly a year, was shut down, the Navy Club's influence on the executive committee dropped significantly. Fengcheng Wheel was no longer a place that some members were keen to visit. This result is perhaps the most unexpected.
Of course, it is a pity to leave this cold storage idle. Another task given by the Planning Commission to the Works and Energy Commission is: to study how to use gas to drive the auxiliary electrical machinery on the ship so that it does not use stored diesel at all?
"Of course it's possible." Zhan Wuya said with a smile, "In reality..."
"What, unrealistic?"
"It's not unrealistic, but it's unnecessary." Zhan Wuya said, "The ship can obviously connect to an external power supply."
Modern ships can completely use the power supply on the shore after entering the port, and the Fengcheng Ship can also do it.
"To put it bluntly, as long as the installed capacity of Bobu Power Station is expanded, there will be no need to continue to power the marine auxiliary engines in Fengcheng."
Zhan Wuya continued: "Of course it is possible to use gas instead of diesel to fuel the auxiliary engines, but the laying of the pipeline is a big problem."
The implication is that it is unnecessary.
Xiao Zishan reminded him: The auxiliary engine is a large group, and its light output power is greater than all the pot camel machines in the entire Bopu Power Station combined. Such a large group of planning committee is not willing to stop it. By then, maybe Bopu will have to rely on Fengcheng Wheel’s auxiliary electromechanical equipment.
"Yeah, that's true. But I haven't really played with such a big piece of marine auxiliary equipment, so I don't know what to do with it."
"Anyway, this matter can be studied slowly. Don't worry." Xiao Zishan comforted him, "You should think about building a real gas refrigerator like this."
Xiao Zishan thinks that it won't be long before every traveler's house can be equipped with a small gas refrigerator - provided that gas pipelines can be laid safely into the house, and perhaps in the future, gas lights will be installed in indigenous houses.
As for the animal-powered ice machine that Zhan Wuya worked so hard to build, it was safely transported to Guangzhou. Then Mo Xiaoan received a telegram: "Make a hot water bottle and a large-mouth thermos bucket." The ice was made, but there was no place to store it.
Noila Mo sighed, got up and went to the glass factory. He suddenly thought: In fact, thermos bottles are also a good trading commodity!
Making thermos bottles is already a piece of cake for glass factories. Especially after they have mastered the mold blowing technology more skillfully, they have achieved a breakthrough in blow molding, which was originally the most difficult. With the mold, they no longer have to rely on the blowing workers' hands to feel. Hundreds and thousands of identical finished products are manufactured.
The key to a thermos is the bladder, which is essentially a glass bottle with a hollow sandwich. When manufacturing, the technology of combining large and small bottles is actually used.
First, the worker dips a small amount of glass liquid into the glass liquid and blows it into a glass bubble. After cooling it slightly, the glass bubble is continuously dipped in the glass liquid and blown continuously. Then it is lengthened and quickly put into the mold. Turn the air blower enough to open the model and create a preform.
The glazier then repeated the task, but using a smaller model. In fact, in the glass factory, compressed air is used to blow the molds in batches. Now they have no compressed air available, so they will still use manual labor for the time being.
Mo Xiao'an watched a young man named Huang Zhongshan skillfully blowing the preforms one by one. His movements were as smooth as flowing water, and he couldn't help but nod his head repeatedly.
"This is the fastest and best among the apprentices." Xiao Bailang sat on a wooden box wiping his sweat. He was now in charge of both the ceramics factory and the glass factory. He was roasted wherever he went.
"Be enlightened."
"It's a pity that even if you have the understanding, you can't make a blown glassware."
So far. Almost all the slightly more complex products of the glass factory are blown or molded. The workers in the glass factory have not yet mastered the technology of making various products using just blowing, scissors and pliers - because the time travelers themselves don't know it either.
"We need to capture some European glassmakers!"
"There are no European glassmakers in Asia." Mo Xiao'an said, "Europeans who come to Asia are basically scum."
Xiao Bailang said nothing, paying attention to the operation of the entire workshop to see if it was in order. The weather has been hot recently, and Ji Sixui was away from the factory for a long time because he was going to start trial production of the coal chemical plant. The labor discipline in the glass factory was somewhat lax. Xiao Bailang immediately implemented labor discipline as soon as he arrived at the factory.
Xiao Bailang did not engage in any political and ideological work, and directly arrested several foreign labor elements into the labor reform team - they were only released after Wu De's intervention. However, in this way, the production efficiency of the factory has improved a lot. Now as soon as he glanced at it, the whole workshop fell into silence.
"You can't do it like this." Mo Xiao'an couldn't help but remind him, "As long as you use coercion, people will not accept it."
"I know, I know that kindness and power are equal parts." Xiao Bailang said casually.
"Okay. Let me ask the food factory to send you some kvass here."
"Chief, the gas station said it can deliver gas..."
"Okay. Just ask someone to bring it to you." Xiao Bailang put on his sunglasses and walked to the gas nozzles that had just been installed. There was a row of yellow copper nozzles. He waved his hand: "Let's get started."
Several workers unscrewed the valve, and red flames immediately spurted out from the combustion head. Xiao Bailang put on his thick labor protection gloves. Carefully adjust the flame until blue flames are sprayed out.
"Prepare the interface!"
Huang Zhongshan quickly brought over the two glass bottle preforms, one large and one small, that had just been blown from the annealing kiln with pliers. Xiao Bailang first burned the bottom of the large bottle and the neck of the small bottle with gas, and then cut them off neatly with a blade. Then he put the small bottle into the large bottle and filled three small pieces of cork between the large and small bottles.
Officially speaking, asbestos particles should be used, and the Works and Energy Commission can only temporarily use substitutes. Its function is to maintain an equal gap between the inner and outer bottles so that they will not shake. Another function is to strengthen the structural strength of the bottle. After the bottle bladder is made, the only connection between the inner and outer bottles is the bottle mouth. After filling with water, the bottle mouth is easily broken. After inlaying asbestos, it is equivalent to adding three additional support points.
Then he heated the large bottle inside the small bottle over a gas fire until it was half molten. This crucial step is coming. Xiao Bailang looked seriously and pulled up the pliers to grab the half-molten glass, and carefully closed the gap at the bottom. This process seems simple, but it requires certain technical requirements for manual operation. It not only requires the bottom of the bottle to be sealed smoothly and tightly, but also requires a thin glass tube. Modern thermos bottle companies all use automatic bottom-drawing machines to complete the process.
Xiao Bailang tried several times but failed. His face was burned red by the gas fire. He put down the pliers, took a few breaths, and asked the others to give it a try. After struggling a few times, I finally sealed the bottom as required.
Next comes the silver plating process. The bladder of the thermos is plated with silver nitrate. The silver plating agent is injected into the space between the bile walls through the small glass tube reserved at the bottom of the bottle. With the basic supply of three acids and two bases, this is no longer a problem. After pouring out the remaining liquid, a layer of bright silver was left on the entire wall of the glass bottle, as bright as a mirror.
The workers let out a surprised sigh. In fact, they have already seen the "secret skills" of the time travelers when making mirrors. There were quite a few greedy eyes in the crowd looking at the residual liquid poured out of the bottle.
After silver plating, the workers poured distilled water into it, washed it and dried it. Xiao Bailang used a gas fire to burn the glass tube at the bottom of the bottle and then put it into the exhaust pipe - this simple exhaust machine. The machine is designed and manufactured by Zhong Lishi. It is a very simple pumping type and can barely reach the level of rough vacuum.
While pumping out the gas, use a gas fire to heat the outer bottle to promote gas expansion so that the gas can be pumped out quickly. Of course, the home-made air pump cannot measure the air pumping condition. Xiao Bailang had to use the most primitive method and try again and again until he found the best pumping time! ~!
