Chapter 178 Research and Development!

The applause fell, and the simple and rude establishment ceremony ended, and the grass stage team of the seven-tower installation was officially established.

"Everyone sits casually, I don't have any rules. Before the official start of the project, I will tell you something to clarify the concept of developing this term." Yu Hua smiled, raised his right hand, raised his index finger, and moved towards Lin Wan and others. The man said slowly.

"R&D?"

The three of Lin Wan pondered over this familiar but different word, all their eyes focused on Yu Hua, waiting for the confusion.

"What is research and development? First of all, this word originated abroad. The English word was originally Research & Development, and many domestic translations are research and development. In fact, it is more appropriate to translate research and development here. The definition of research in the scientific field is Explore the unknown, and development is defined as the systematic activity behavior of creating new items through known science and technology and new knowledge." Yu Hua seriously explained the concept of research and development.

"Research and development..." Lin Wan's eyes suddenly lit up, carefully considering this explanation.

Zhou Yuan and Fang Yu seem to have realized something, a little ignorant, and a little enlightened.

"R&D is divided into two types, scientific and technological research and development and technological research and development. The research on scientific principles, laws and theories is called basic research, while the applied research and development of science and technology is called applied research and development."

Yu Hua paused: "Technology research and development refers to the systematic activities of transforming scientific research results into products in order to substantially improve technology, products and services. By clarifying this concept, we can have a good comprehensive understanding of the seven-tower device research and development project. ."

"So, the seven-tower device is essentially a technology research and development, using known science and technology and new knowledge to create new things." Fang Yu thought about it carefully, and after thinking about it, his eyes turned to Yu Hua.

Yu Hua nodded: "Yes."

"Old Yu, thank you." At this time, Zhou Yuan, whose mind finally turned around, glanced at Yu Hua, a touch of emotion in his eyes, and thanked him.

Yu Hua's previous explanation of this work was by no means simple. It seemed that it was just a piece of teaching. In fact, it was teaching them extremely valuable scientific research concepts.

This is teaching a man to fish!

"Don't talk about this, let's have a meeting." Yu Hua shook his head, and then started the first technical seminar as the team leader. The three of them sat at the corresponding desks and took out their notebooks and pens as if they were listening to lectures in class.

A good memory is not as good as a bad writing, and the knowledge written on the paper will not be lost.

The theme of the first technical seminar of the grass stage team was to clarify the key points of the research and development of the seven-tower device, and to divide their work accordingly.

In short, it is to mark the difficult points first, and then divide the work according to the difficult points, and divide the labor and cooperate to improve the R&D efficiency.

"Xiaoyu, Lao Zhou, how do you know about the sulfuric acid production process and the chemical industry?" When everyone was ready, Yu Hua turned his eyes to the two and asked.

"Generally, I only know the general principles and chemical reaction formulas. The specific process and process of sulfuric acid production are not clear. I know the lead chamber and tower type. The chemical industry is fine. My textile factory is located opposite Yongli. situation." Zhou Yuan answered truthfully.

Yu Hua nodded and turned his eyes to Fang Yu.

"I am very familiar with the production process of sulfuric acid. The principle of the tower method is the same as that of the lead chamber method. It is divided into three steps: the first step is gas generation, the second step is oxidation, and the third step is absorption. The high temperature gas is divided into two parts and enters the reaction tower, a part of the high temperature gas enters the denitrification tower, and the other part enters the acid-forming tower. Sulfur oxide, and further to sulfuric acid."

Fang Yu immediately connected, and said slowly: "Next, it will be moderately oxidized in the oxidation tower to form dinitrogen trioxide, and then it will be treated in the shower and absorption tower to remove the nitrogen oxides, sulfur trioxide and water in sulfuric acid containing nitric acid. Contact is to generate crude dilute sulfuric acid with a concentration of about 76%, to obtain concentrated sulfuric acid with a concentration of 98%, and then add sulfur trioxide to obtain a sulfuric acid product with a concentration of 100%.

expert.

After listening to Fang Yu's answer, Yu Hua immediately gave an evaluation in his heart. As expected of a genius in the school whose chemistry grades were on par with him, he did have two strokes.

Being able to understand the principle of the tower method and the general production process is much more than ordinary people, and it is not easy to understand the reaction formula and reaction process.

The highest concentration of sulfuric acid in industry is about 98%. As for 100% sulfuric acid, it is not actually a 'pure substance' as defined by the physical definition, but a sulfuric acid product obtained by adding 98% concentrated sulfuric acid to sulfur trioxide, which is called oleum.

The concentration can not only reach 100%, but even exceed this limit, reaching 105%.

Fang Yu took a breath and continued: "Germany is the most advanced technology in the world's sulfuric acid industry, and the United States is the largest. Germany adopts an improved contact production process. The specific catalyst and chemical formula are not clear, and the daily output is extremely high. I used to I read a chemical journal, which records that a single contact method equipment in a German chemical company’s sulfuric acid plant can produce more than 20 tons of equipment per day, and the annual output of five contact method equipment can reach 1930 tons. Americans use the contact method and improved The tower method is parallel. In 13, the daily output of the tower device was about 15 tons. The year before last, the tower device achieved a technological breakthrough of 22 tons. Yu Hua, I am curious where you made a breakthrough or improved the tower method to [-] Ton-level theoretical daily output."

The voice was full of curiosity.

Compared with Zhou Yuan, who doesn't know anything, Fang Yu's knowledge of the chemical industry is no less than that of senior people. He even uses the high-end platform of Peiping No. [-] Middle School to understand more in-depth things.

The pursuit of higher production of sulfuric acid has never ceased in the chemical industry of various countries. Since the birth of the tower method in 1911, all countries in the world have been striving to improve the tower method in order to obtain more output. American chemical companies are the first to reach new heights, and the tower production process can achieve a daily output of 15 tons of single equipment.

Now, Yu Hua has actually built a 22-ton tower production equipment. She is really curious about where Yu Hua achieved a technological breakthrough, making the tower method reach a production height comparable to the early contact method.

"Three places, first, pressurization and heating. Although the volume fraction of SO3 reaches 91% under normal pressure, the nitrification reaction can still be accelerated by increasing the pressure and temperature. Second, I am improving the production process and canceling one Add a nitrification tower and an acid-forming tower. Third, add a boiling furnace to supply gas outside the reaction tower. After mathematical modeling, the theoretical maximum output in 24 hours is 22.1 tons. Jinyu, take out the original blueprint and give it to Xiaoyu Let's take a look." After glancing at Fang Yu who was full of curiosity, Yu Hua smiled, and without giving in, directly told the core secret of the seven-tower device, and then said to Lin Wan.

"So that's the case..." Fang Yu's eyes lit up when he heard the secret Yu Hua told, and the place where he was puzzled before finally turned around.

The secret of the daily output of 22 tons is so...

simple!
"Xiaoyu, here." Lin Wan took out the well-kept original blueprint from her backpack and handed it to Fang Yu.

Fang Yu hurriedly took the original blueprint, opened it, and saw a beautiful mechanical blueprint like a work of art. The core design of Yu's Seven Pagodas was presented, three acid-forming towers, two denitrification towers, one Boiling furnaces, coupled with increased pressure and temperature, allow for increased reaction rates.

In Fang Yu's view, the whole design is simple and easy to use, which is simply ingenious.

"This is the mathematical model of the seven-tower device. I like to speak in mathematics, and I don't like to brag." Then, Yu Hua took out a piece of manuscript paper from his backpack and handed it to Zhou Yuan.

On the manuscript paper, the mathematical model of the seven-tower device described by mathematical language is recorded, and the entire production volume and process of sulfuric acid can be calculated mathematically.

And this is the real soul of the seven-tower device, and its importance is no less than the original blueprint of the seven towers of the Yu family.

In the field of science and technology, the key to distinguishing whether the other party is bragging is to ask him to describe his idea in mathematical language. If he can describe it, then the idea will become a conjecture.

If I can't describe it, I'm sorry, Minke is one.
