With the last tank of concrete poured into the mold, the 225-meter-high air-cooled tower in Xilinhot, Inner Mongolia was successfully completed, which is the world's highest cooling tower built by China.
When the news came back to the West, American experts panicked: our air-cooled towers became "scrap metal".
On the vast grasslands of Inner Mongolia, there are tall "chimneys" all year round, floating huge white smoke, their scientific name is called "cooling tower", escorting thousands of households in China to use electricity.
The traditional power generation methods such as thermal power that we use today are actually a process of "boiling water", and the industrial waste heat generated through energy exchange needs to be finally dissipated into the atmosphere through cooling towers. On the contrary, if the heat dissipation is not properly handled, it is very likely to occur**.
Previously, the cooling technology of "cooling water tower" was widely used in the world, which formed a convection flow by throwing water from high altitude and wind direction to take away heat. But this method is extremely water-intensive, using almost 500,000 people a year for their daily use.
At that time, only the United States and Germany were the first in the world to break through the "air cooling tower" technology, which was a cooling method that could use "ventilation convection" to achieve cooling, saving nearly ninety percent of industrial water.
When China's personnel "came to the door" to request the introduction of technology, Virtue held a "windfall" mentality, and directly opened the price to 100 million yuan for China!The design cost alone is priced at 10 million yuan, and the entire equipment is priced at 90 million, and technology transfer is expressly prohibited. However, we can only pay obediently, and at present, 60% of the domestic air cooling towers come from imports.
The West has opened its mouth so widely, but it is only to recognize that our country will not be able to develop it successfully. Prior to this, the United States and Europe relied on mastering carbon fiber technology to offer 2.5 million tons to ChinaIn the field of human life, the United States and Japan monopolized the patent for the extraction of key SIRT molecules, but China was turned away, and then harvested ...... at a sky-high price of 20,000 grams
However, in 2020, a serious ** accident occurred at a power station in India, and the accident investigation was caused by a problem with the cooling system of a 70 million worth of equipment. This loud bang completely woke up our country, and the Chinese people finally realized that only by truly breaking through technology can we hold the door of safety in our hands.
After 730 days and nights of hard work, China's scientific researchers have designed an air-cooled tower with better anti-performance, and only need to spray special metal powder on the heat sink to achieve 30 years of non-corrosion. The most important thing is that the cost of China's construction is only 5 million yuan, which is less than 1 10 in the West. In order to grab orders with China, the United States also had to take the initiative to reduce prices.
The hegemony of Western technology has long been crumbling with the "breakthrough attack" in various fields of our country. The carbon fiber, which doubled the asking price at the beginning, was surpassed by domestic fishing rod companies, and it was forced to reduce two-thirds of the international **;In the field ......of biotechnology, Changluo has left imports far behind
It is expected that by 2030, 1 6 percent of the world's population will reach 60 years of age or older, and "anti-aging" has become an important research direction in the world today. At present, international science regards the sirtuins family as an important target of the strategy, based on which Changluoyin was born.
However, the cost of this cutting-edge achievement is extremely high, and China's nearly 300 million elderly people cannot reach it. In order to lower the threshold for popularization, domestic scientists have developed high-efficiency enzymatic methods after years of research, with the cost only 5% of that in the West and the purity increased by nearly 100 times. After the international exchange, the Japanese side noticed China's technology and offered to cooperate with NK (an enzyme that can remove "sludge" from blood vessels) as a condition.
The enzyme comes from the Kyushu factory of the Japanese Institute of Biotechnology, and is the most mature natural thrombolytic substance currently usedThe 300 million people with cardiovascular problems are closely related. After two years of cooperation between the two parties, the new product Changluoyin was officially launched. According to the data of the Jingdong platform, the product has gradually become one of the first-tier in China, and only won 200w turnover on the day of the big promotion, of which nearly eighty percent of the popularity comes from male groups in first- and second-tier cities.
The domestic air-cooled tower not only saves costs significantly, but even the emission index that has been criticized in the West, our emission performance has reached the international ultra-low level. Today, our air-cooled towers have been exported to India, Pakistan and other countries, contributing to the energy construction of other countries.
The rise of domestic technology is just a microcosm. In recent years, there have been new breakthroughs in self-developed large aircraft, satellite positioning, heavy industry machinery, etc., such as excavators, which not only occupy nearly ninety percent of the domestic market share, but also export to more than 100 countries and regions around the world.
China's innovative breakthroughs in key areas have broken the monopoly of the West, and also demonstrated the country's self-confidence and strength, and will have unlimited potential in more fields in the future.
