The central cooling tower, judging from its name, is as ordinary as the central shopping mall, central primary school, and central hospital.
But the central cooling tower is the first super project launched by the Kingdom. The scale of the project is larger than the green artificial river and artificial lake section.
The center point of its facility is next to the Magic Academy, right in the middle of Phoenix, New City, and New Pettus. It will be responsible for all low-temperature steam and hot water cooling work in the three cities, and deliver cold water of 4 to 10 degrees to the three cities.
The cold water will be mainly used for steelmaking, power generation and the overall cooling of the foundry workshops of various enterprises, to improve the working environment, and for use in city-level refrigerated cold storage. The water will be rotated twice in each area to return to normal temperature before being used for spraying and quenching, and then collected Return to the hot water pipe and send it to the cooling tower.
The heat generated during the operation of the cooling tower is circulated through another set of closed pipelines in the plantation forest from Phoenix to New Pettus and the Western Ice Forest to provide heat supplement for the ice trees.
The reason why the two systems need to be separated is because the temperature inside the Ice Forest is too low and there is a risk of freezing at the corners of some pipes. Therefore, the heat pipes need to be mixed with alcohol to reduce the freezing point to subzero temperatures.
Refined oil has better low-temperature resistance than a mixture of alcohol and water, but the risk of fire and explosion is greater.
The point is that the total liquid volume of this set of pipelines is a bit large, and the refined oil is too expensive, so it should be based on water so that it can be used later.
In fact, if you want to make it simpler, it would be easier for each city to build its own cooling system and connect the hot liquid to the heat dissipation pipes. The construction period and cost will be reduced a lot.
However, Wang Qi is relatively wild. He has follow-up plans and needs to locate the cooling station in the center of the three cities.
Between the three cities, there are many large and small hills, which look very irregular.
After the exploration expedition team's aircraft flew over the finely calibrated map over and over again, and with the help of ground personnel to mark the contour lines, it was easy to see from the map that only three dams with a height of several tens of meters in this area could block a dam. A super reservoir with a total storage capacity of more than 9 billion cubic meters.
Water is the most important factor limiting the size of cities, especially in industrialized areas, and its importance is unparalleled.
Wang Qi must consider that there is no suitable excuse to continue external expansion, so there must be more than just Wind Valley in the existing territory, which can accommodate over a million people in the future.
If there are no natural conditions, then make it man-made!
When the water is actually stored to that extent, the water level of the reservoir will be a hundred meters higher than that of Phoenix City and more than eighty meters higher than that of New City. The risks are not small, so let’s not talk about that now. The population of Wind Valley is still far from the million level. By an order of magnitude, it’s not urgent.
In short, the location of the central cooling tower is determined by the needs of the three cities and future planning. For this reason, it is better to spend more man-hours and materials for remote heat conduction.
Since it is a super project, it naturally does not mean that it will be built immediately. Each of the three cities, Fenggu and Green City Municipal Government has an office to coordinate and carry out preliminary demonstration and inspection work.
The argument is actually just a formality. After all, it is an order from the king. The most you can do is change the address. It is impossible to stop doing it suddenly.
The survey work is quite complicated. It also needs to take into account the replacement and repair of pipelines after the reservoir is filled with water in the future, so it is impossible to walk in a straight line in many places.
Companies also have preliminary work to do.
In addition to being large, the central cooling tower itself has no technical content. It is just a two-tube heat exchange device.
But large pipelines require specialized research.
Existing chromium and nickel steels have excellent corrosion resistance, but the output of chromium and nickel is relatively limited. It is not enough to lay water pipes of this scale. We must find ways to reduce the proportion of chromium and nickel added while ensuring corrosion resistance. .
The solution was clear, cast iron.
This kind of large water pipe can only be cast by centrifugal casting. Centrifugal casting of small parts has been realized in automobile factories, but it is not the same as water pipes. There is no mold inside when the water pipe is cast. Instead, the centrifugal casting is completed, and then smaller parts are inserted. The cold piece cools the inner surface and demolds.
In addition, in order to ensure that the temperature does not flow randomly in non-ice forest areas, the outer surface of the cast iron pipe cannot be made too smooth to provide sufficient adhesion for the cement layer, which also requires special technology.
Even if it is built, it still has to be transported to the construction site. This part alone is a task that is difficult to complete in other areas.
Fortunately (this chapter is not finished yet!)

The automobile factory is building a heavy-duty truck, but the butyl rubber can't keep up, so a few more wheels can be used.
The part that still needs to be addressed is the crane.
The hanging tower cannot meet the construction needs of laying pipelines, and it can only be a crane that can run by itself.
This thing has already taken shape.
The kingdom has not regulated vehicle modifications for the time being. Some people took the initiative to install spreaders on some steam trucks, which were manual hoist cranes or pulley block booms.
However, we still have to work hard to lift the water pipes made of cast iron and cement.
We're talking about plumbing, but a lot of the work falls on the auto plants.
Since its establishment, Xincheng Automobile Factory has only launched one model and two types of wheels.
Before the official heavy truck-related information was sent, in addition to asking the locomotive chief to develop the technology of six-cylinder engines, they were also trying to make a single-cylinder diesel engine themselves.
It was built, but not the single-cylinder tractor.
Single-cylinder tractors and generators are often seen in the wasteland by the second generation of disasters. Of course they know what they look like. Although the automobile factory is mainly populated by people from the new city, there are also a few night tribes and sharp blades. It’s just that the director of the automobile factory disliked the fact that this thing had no technical content and was too easy to copy, so he sold it directly to Fenggu without producing a finished car, and the private companies there made tractors, water pumps, temporary generators for construction sites, etc.
And just as the factory director expected, because the structure was too simple, workshops producing single-cylinder engines soon appeared in Heishui.
The car factory specially sent people to buy one.
It is very rough, and the surface of the cylinder shell is full of pits. However, the structure is simple and extremely durable. It can still be started like this. The starting test power is close to eight horsepower, but the sound is a bit loud compared to the power.
If this trend continues, there will be no profit from this thing within two years.
At this time, the automobile factory obtained most of the drawings of the six-cylinder engine military light armored vehicle. It lost love for the single-cylinder on the spot. It went directly to its superior Xincheng Office of the Ministry of Industry, submitted an application, and sold the single-cylinder production technology.
Unexpectedly, in the process of developing cranes, the single-cylinder engine would have the opportunity to be used again!
To lift a water pipe of twenty tons or more, no matter what type of pulley it is, there is no way to use human power. Otherwise, the chain at the back end drags a hundred meters and the front end only rises one centimeter. Can one pipe be hoisted in one day?
Three options.
Electric motor, single cylinder engine, multi-cylinder engine.
In the end, I was still not confident enough and chose a single cylinder.
According to the requirements put forward by the Ministry of Industry, the crane must be able to lift water pipes at least ten meters long.
The length of the water pipe determines that the boom must be telescopic. First, the telescopic arm requires a power. In addition, the crane itself needs to be able to rotate on the vehicle, and the power of the hoisting itself must be integrated into a set of power sources. I still don’t quite understand.
Simply put, install multiple single cylinders, each doing their own thing, and make them easy to disassemble. If the crane power is not enough, remove the telescopic power source and put it on the crane power.
It's a bit weird, but the drawings were approved after I submitted them.
The official opinion sent back stated that the use of single-cylinder engines is conducive to lowering the maintenance threshold, but multi-machine collaboration is still too complex in operation and needs to be continued.
This means that the production license has been approved, but large engines will still be needed in the future.
The automobile factory had no time to pay attention to this request at this time, because when the prototype was hoisted in its yard, the crane arm broke.
