What are the typical energy-saving and environmental protection enterprises in China?

With the rapid development of economy, how to save energy and reduce emissions has become a reality that enterprises have to think about. In Ouhai Economic Development Zone, which is characterized by "Wenzhou Model", the problems of dust pollution, water pollution, cultivated land loss, high energy consumption and low support for scientific and technological enterprises must be solved throughout ouhai district.

When the reporter asked whether so many village-run enterprises had taken measures to control the environment and save energy, the local villagers replied that they had, but the effect was not good. Wenzhou Weishang Technology Environmental Protection Equipment Company spent 1.3mg a year researching and producing environmental protection and energy-saving technologies, and developed energy-saving countercurrent heat exchanger technology, UEC series purification equipment and other waste gas pollution control technologies, each of which is better than the national pollution emission index by more than 50%-90%. Through the monitoring of provincial and municipal environmental monitoring departments, the control efficiency of sulfur dioxide reached over 95%, and the oxidation and phosphating of smoke and dust were realized.

Among them, why is the energy-saving countercurrent heat exchanger as high as 20-40%, and the waste gas pollution control is at the highest level in the world, but it has not been supported by the government and trusted by the market? With this question, we interviewed Huang, the legal person of Wenzhou Technology Environmental Protection Equipment Co., Ltd.

Difficulty in technology popularization

200 1, 1 year1October, the company applied the patented technology to the cooking fume purification treatment in the catering industry, and carried out cooking fume purification in several hotels. The actual use effect of the equipment is very good, which solves the problem of hotel fume pollution reflected by residents. As a result, the competent department of environmental protection claimed that the equipment could not be installed and tried without national certification, so it withdrew from production.

In the same year, the patented technology was applied to boiler dust removal and desulfurization. After monitoring, the flue gas purification efficiency is 99.6%, and the desulfurization efficiency is 98%. After treatment, the flue gas emission concentration is below 32 mg, and the sulfur dioxide emission concentration is 50 mg. However, environmental protection personnel and polluted enterprises said that the environmental protection department did not accept the installation of VIA technology products, which made enterprises afraid to buy the company's equipment.

In order to survive, the company introduced the patented technology of boiler energy saving. "Energy-saving countercurrent heat exchanger" is applied to coal-fired boilers, oil-fired boilers and liquefied gas boilers, and the energy-saving efficiency is about 20%-40%. As a result, users were afraid to use it later, because the boiler manufacturer, boiler research institute or installation team all threatened the enterprise that "China can't have such technology", and it was irresponsible to say that the boiler was broken.

Facing the lack of honesty

In order to protect the achievements made in more than ten years' efforts and reduce the country's energy consumption, the enterprise later adopted a sharing management mode, that is, it did not accept the equipment payment from the user enterprise, and shared the energy-saving coal-based oil with the user enterprise equally during the use process. Facts have proved everything. After many tests after installation, the result shows that a leather enterprise needs to consume 9 1.63 tons of coal to produce one ton of wastewater before installing energy-saving equipment, and the daily wastewater output is 322.5 tons. After installing energy-saving equipment, the coal consumption per ton of wastewater is only 76.6 15 kg, and the wastewater output is 322.5 tons/day. Tomorrow, the output will be increased by 27.5 tons, and the energy consumption per ton of wastewater will be reduced 15.02 kg. This set of data tells enterprises that only by saving can they gain an advantage in the competition.

Faced with the huge amount of money saved, some enterprises abandoned the credit in order to win the market when they wanted to resettle the enterprises that had visited the equipment, and said to the visitors that "this equipment is not energy-saving". In order to survive, VIA can't take those dishonest enterprises to court. Mr. Huang told reporters that if the lawsuit is lost, not only will the money be lost, but the patented energy-saving technology that has been painstakingly studied for more than ten years cannot be further promoted.

Call for a change of mind

"The development of science and technology is the fundamental way to solve the energy problem." This is put forward in the 11th Five-Year Plan of energy development. The 11th Five-Year Plan for energy development reflects China's efforts to make independent research and development, introduction, digestion and re-innovation of energy-saving and environmental protection technologies the key areas for government investment in science and technology and the promotion of high-tech industrialization.

In addition, starting from the 11th Five-Year Plan, the country is accelerating the application of advanced and applicable technologies, strengthening the technological transformation of energy frontier to upgrade traditional industries, and promoting the wide application of new technologies, new processes, new products and new equipment for energy conservation and environmental protection through technology development, demonstration and popularization. In addition, it is also the direction of national efforts in the next five years to speed up the elimination of backward technologies, technologies and equipment, focusing on the elimination of backward production capacity, process equipment and products in high energy-consuming industries such as steel, nonferrous metals, chemicals, building materials and electricity.

In recent years, people no longer blindly pursue high-speed economic growth, but turn their eyes to "green", and put forward a green economic accounting method, which integrates resource consumption, environmental loss and environmental benefits in the process of development into the evaluation system of economic development, and uses this system to comprehensively evaluate the comprehensive strength and development potential of countries and regions.
