Chapter 268 NO.1!

On the drawing, this is the third design scheme of the cooling tower of the air separation plant. It adopts the principle of open evaporative heat dissipation, and uses water as the internal circulating coolant to absorb the heat of the system and discharge it into the atmosphere.

At present, the theoretical design has been completed. Yu Hua needs to carry out thermal calculation for the entire cooling tower design, mainly to calculate two data, one is to calculate the theoretical design cooling total amount and the design index through the known water load and heat load under ideal meteorological conditions. match.

The second is to obtain the numerical change curve of cooling water temperature under the set water load, heat load and meteorological conditions according to the known parameters of the cooling tower, 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 the cooling tower, the total cooling amount and the degree of temperature difference are the core indicators to measure the comprehensive performance.

The two cooling tower design schemes previously designed are both closed cooling tower schemes, each with its own shortcomings. The first design scheme is qualified in terms of total cooling, but the temperature difference is not enough. In the second one, a third set of circulation is added to achieve the temperature difference. System, the temperature difference is up, but the actual manufacturing difficulty is too high and the cost soars.

The cost of the second cooling tower design is almost 1.5 times that of the first design.

Zhuang Qianding weighed it over and over again, and had to give up the mainstream design of closed cooling towers adopted in the West, retreated and chose the open cooling tower design.

The advantage of the open cooling tower is that the cost is low and the structure is simple. The internal main body is composed of a set of inner circulation and a set of outer circulation. It can be cooled only by water, and the cost is only one-third of the closed cooling tower.

The disadvantage is that the water consumption and power consumption are high, the use cost is more than 30% higher than that of the closed cooling tower, and it must be shut down frequently for maintenance, and it cannot maintain long-term continuous operation for more than half a year.

The closed cooling tower does not have such a problem. It has a high energy efficiency ratio and is suitable for use in harsh environments such as drought, water shortage, and frequent sandstorms. The environmental adaptability is very good.

In addition, oils, alcohols, and quenching fluids other than water can also be used as the cooling medium. The cooling medium has no loss and stable composition during operation.

The only downside is that it is expensive.

Unfortunately, for the base area, being expensive is the original sin.

"Professor, this is the total amount of cooling, the value change curve of water temperature and the maximum temperature difference. According to the calculation results, the internal structure design of the cooling tower meets the requirements, which can ensure sufficient cooling amount to maintain the operation of the air separation plant." Yu Hua's eyes revealed a touch. Rational color, when the thinking computer completed the simulation calculation of the third design plan, quickly wrote the three data on paper and handed it to Zhuang Qianding.

In the third design scheme, the total cooling amount 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 flattens.

"Okay, with this data, even if the theoretical design of the main body of the cooling tower is done, you can't stand it. Can you hold us all together, take out all the designs, and create an air separation plant in one fell swoop." Zhuang Qianding took it in his right hand. Drafting the manuscript paper, nodded with satisfaction, glanced at Yu Hua, and said with concern.

Thirteen hours of high-intensity R&D work has been carried out today. During the entire R&D process, Yu Hua has the heaviest workload.

Not only to assist in the design, but also responsible for the calculation.

I'm fine. Although I'm mainly responsible for theoretical design, I don't worry about calculation at all.

Of course, it is thanks to Yu Hua's terrifying mathematical calculation ability that the progress of the air separation plant research project is so fast. Take the cooling tower design as an example, the calculation amount of a design scheme often requires a ten-person R&D team for half a month. above time.

What about Yu Hua?
5 minutes!
I have to say that Zhuang Qianding really likes the research process of death, which only requires design but not calculation. He can freely and freely present his inner design inspiration.

"It should be fine." Yu Hua felt his slightly dizzy brain and nodded lightly. According to his current state of energy, he could still maintain a high-intensity simulation calculation for 3 minutes and regular data calculation for about [-] hours. There should be no problem. ,
High-intensity simulation calculations are mainly performed by thinking computers, while routine data calculations are based on efficient study time every day.

Yu Hua now uses intermittent operation mode for high-intensity simulation calculation and routine data calculation. For example, if high-intensity simulation calculation is required for 1 minute, then, after 1 minute, it must be stopped immediately, and the calculation time will not be wasted, in order to maximize the use of daily It has been increased to a total runtime of 52 minutes.

The calculation of conventional data is the same.

There is only one purpose for doing so - to serve Professor Zhuang in an all-round way.

Auxiliary design and calculation data, this is Yu Hua's positioning for himself, and the behavior of consuming thinking computer computing time in order to verify a design idea in the past no longer occurs.

No way, in terms of practical experience and level, it is no exaggeration for Professor Zhuang to dump him [-] miles away. In order to solve a technical problem, Yu Hua needs to verify three design ideas and confirm which one is the optimal solution.

Professor Zhuang, who has rich experience and top level, directly gives the optimal solution, which greatly saves time and efficiency.

In the field of mathematics, Yu Hua has full confidence, but in mechanics and engineering, Yu Hua has to be No.1 in Professor Zhuang!

Now, with Professor Zhuang joining the air separation plant research project, the entire research and development efficiency has been completely improved by orders of magnitude. Yu Hua originally thought that it would take about ten days to complete the air separation plant project.

result……

Professor Zhuang joined yesterday morning, and the air separation plant project is almost finished tonight.

Yu Hua wanted to say something about Professor Zhuang's eternal god, but after thinking about it, let it go.

"Okay, just say if you feel uncomfortable, don't hold on." Zhuang Qianding instructed, then took out a brand new design drawing, held the pen in his right hand, and started the design work.

Inspiration erupted, thoughts flowed like a spring, Professor Zhuang, who was in the best R&D state, showed his top talents on the design drawings without any scruples. His computing power may not be comparable to Yu Hua, but in the field of machinery and engineering, he dared to be the second. No one dares to be number one!

The low-level mistakes that Yu Hua made in the compression structure will never happen to Zhuang Qianding.

Yu Hua stood quietly beside him, staring at the design drawings on the workbench, like a sponge, constantly absorbing Professor Zhuang Qianding's design ideas and experience, not letting go of any opportunities to improve himself.

Time passed by, and there were more and more design drawings on the laboratory workbench. Zhuang Qianding showed off his talents and abilities belonging to top mechanical experts. Yu Hua performed calculations again and again with due diligence and gave a series of data. , like a catalyst to accelerate the development of the entire project.

Under the highly tacit cooperation between the two, the prototype of the world's first [-]-class air separation plant has already appeared, and all theoretical designs are about to be completed.

The night is getting darker.

The nights in July were sultry and oppressive.
