On the drawing, this is the third cooling tower design scheme for air separation equipment. It adopts the principle of open evaporative heat dissipation and uses water as an internal circulating coolant to absorb system heat and discharge it into the atmosphere.
At present, the theoretical design has been completed. Yu Hua needs to perform thermal calculations on the entire cooling tower design. He mainly calculates two data. One is to calculate the total theoretical design cooling capacity and design indicators through the known water load and heat load under ideal meteorological conditions.
Is it consistent?
The second is to obtain the cooling water temperature numerical change curve based on the known parameters of the cooling tower under the set water load, heat load and meteorological conditions, and obtain the maximum temperature difference.
These two data are very important and are related to whether the entire theoretical design meets the requirements.
For cooling towers, the total cooling capacity and temperature difference are the core indicators for measuring comprehensive performance. The greater the actual total cooling capacity and the actual temperature difference, the higher the performance of the cooling tower.
The two cooling tower designs previously designed were both closed cooling tower solutions, each with their own flaws. The first design solution had qualified total cooling capacity, but the temperature difference was not enough. In the second design, a third set of circulation was added in order to achieve the temperature difference.
System, the temperature difference has increased, but the actual manufacturing difficulty has become too high and the cost has soared.
The cost of the second cooling tower design is almost 1.5 times that of the first design.
After careful consideration, Zhuang Qianding had to give up the mainstream design of closed cooling towers adopted in the West and settle for an open cooling tower design.
The advantages of open cooling towers are low cost and simple structure. The internal body is composed of an internal circulation and an external circulation. It only needs water for cooling, and the cost is only one-third of that of a closed cooling tower.
The disadvantages are high water and electricity consumption, the cost of use is more than 30% higher than that of a closed cooling tower, and frequent shutdowns and maintenance are required, making it impossible to maintain long-term continuous operation for more than half a year.
However, closed cooling towers do not have such problems. They have high energy efficiency and are suitable for use in harsh environments such as droughts, water shortages, and areas with frequent sandstorms. They have excellent environmental adaptability.
In addition, oils, alcohols, quenching fluids, etc. other than water can also be used as cooling media. The cooling media has no loss during operation and has stable composition.
The only drawback is that it is expensive.
Unfortunately, for the base area, being expensive is the original sin.
"Professor, this is the total cooling amount, the water temperature numerical change curve and the maximum temperature difference. According to the calculation results, the internal structure design of the cooling tower meets the requirements and can ensure sufficient total cooling amount to maintain the operation of the air separation equipment." Yu Hua's eyes revealed a trace of
Rationally, after the thinking computer completed the simulation calculation of the third design plan, he quickly wrote the three data on the paper and handed it to Zhuang Qianding.
The total cooling capacity of the third design scheme is 240 cubic meters per hour, the temperature difference reaches 8°C, and the water temperature change curve shows an exponential upward trend and finally levels off.
"Okay, with this data, even if the theoretical design of the main body of the cooling tower is completed, can you still hold on? If we can hold on, we will work hard to take out all the designs and build the air separation equipment in one fell swoop." Zhuang Qianding held it in his right hand.
Drafting the draft paper, he nodded with satisfaction, glanced at Yu Hua, and said with concern.
Thirteen hours of intensive research and development work have been carried out today. During the entire research and development process, Yu Hua has undertaken the heaviest workload.
Not only assist in design, but also responsible for calculation.
Fortunately for me, although I am mainly responsible for theoretical design, I don’t worry about calculations at all.
Of course, it is precisely because of Yu Hua's terrifying mathematical calculation ability that the progress of the air separation equipment research project is so fast. Take cooling tower design as an example. The calculation amount of a design plan often requires a ten-person R&D team for half a month.
above time.
Where is Yu Hua?
Five minutes!
It has to be said that Zhuang Qianding really likes this kind of research process that only requires design without calculation. He can express his inner design inspiration freely and freely.
"It should be no problem." Yu Hua felt his brain that was already slightly dizzy and nodded gently. According to his current energy state, he can still maintain a 3-minute high-intensity simulation calculation and about three hours of regular data calculation. There should be no problem.
,
High-intensity simulation calculations are mainly performed by the thinking computer, while regular data calculations are based on efficient study time every day.
Yuhua now uses intermittent operation mode for high-intensity simulation calculations and regular data calculations. For example, if high-intensity simulation calculations are required for 1 minute, then they must be stopped immediately after 1 minute to never waste computing time in order to maximize the use of every day.
That has increased to a total running time of 52 minutes.
The same goes for regular data calculations.
There is only one purpose for doing this - to serve Professor Zhuang in an all-round way.
Assisting in design and calculation of data, this is Yu Hua's positioning for himself. The previous behavior of consuming thinking computer computing time in order to verify a design idea no longer occurs.
There was no way around it. In terms of actual experience and level, it was no exaggeration to say that Professor Zhuang was miles away from him. In order to solve a technical problem, Yu Hua needed to verify three design ideas and confirm which one was the optimal solution.
Professor Zhuang, who has rich experience and top level, directly gave the optimal solution, greatly saving time and efficiency.
In the field of mathematics, Yu Hua has full confidence, but in mechanics and engineering, Yu Hua has to say that Professor Zhuang is the number one!
Now, with Professor Zhuang joining the air separation equipment research project, the entire research and development efficiency has completely improved by orders of magnitude. Yu Hua originally thought that it would take about ten days to complete the air separation equipment project.
result……
Professor Zhuang joined yesterday morning, and the air separation equipment project is almost completed this evening.
Yu Hua wanted to say something about Professor Zhuang’s eternal praise, but after thinking about it, he decided not to do it.
"Okay, if you don't feel well, just say it, don't hold on." Zhuang Qianding ordered, then took out a brand new design drawing, held the pen in his right hand, and started the design work.
Inspiration bursts out, and ideas flow like a fountain. Professor Zhuang, who is in the best state of research and development, shows off his top talent on the design drawings without any scruples. His computing power may not be as good as that of Yu Hua, but in the field of machinery and engineering, he dares to be ranked second.
No one dares to claim first place!
The low-level mistakes that Yu Hua made in the compression structure would never happen to Zhuang Qianding.
Yu Hua stood quietly beside him, staring at the design drawings on the workbench, absorbing Professor Zhuang Qianding's design ideas and experience like a sponge, never letting go of any opportunity to improve himself.
Time passed by, and there were more and more various design drawings on the laboratory workbench. Zhuang Qianding showed off his talents and abilities as a top mechanical expert. Yu Hua performed calculations diligently and gave a series of data.
, like a catalyst to accelerate the research and development progress of the entire project.
With a high degree of tacit cooperation between the two, the prototype of the world's first 100-level air separation equipment has been presented, and all theoretical designs are about to be completed.
