Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.

The theme of the conference is: Focusing on the implementation of the “Comprehensive Work Plan of the State Council on Energy Saving and Emission Reduction,†analyze the situation of industrial pollution reduction, exchange experience on corporate pollution reduction, and push the industry emission reduction work to a new level.
Li Yongwu, president of the China Petroleum and Chemical Industry Association, said at the meeting that by the end of 2006, the discharge rate of waste water in the petroleum and chemical industry was 95.1%, the industrial water reuse rate was 85.4%, the CO2 emission rate was 86.9%, and the dust emission rate was up to the standard rate. 86.8%, the dust emission compliance rate was 72.8%; the industrial solid waste comprehensive utilization rate was 80%. The industry "three wastes" comprehensive utilization of the output value of 14.74 billion yuan. Since the country began to carry out environmental risk investigations, petroleum and chemical companies have invested more than 14 billion yuan to improve facilities and conditions, and the ability to prevent environmental risks has been strengthened. However, there is still a wide gap between the international advanced level and the requirements for sustainable development of the industry. In the industrial system, the discharge of petroleum and chemical wastewater ranks first, exhaust gas ranks third, waste residue ranks fourth, and the discharge standard is low and unstable, which has become one of the key factors that restrict the sustainable development of the industry.
To this end, Li Yongwu put forward six opinions: First, recognize the current situation and increase the sense of responsibility for pollution reduction and environmental protection. The second is to take advantage of the industry and regard circular economy as the strategic focus of industrial development. The third is to rely on scientific and technological progress to provide technical support for clean production and environmental protection. The fourth is to actively promote the clean production of petroleum and chemical companies according to the current status of the industry. The fifth is to promote typical experiences and give play to the exemplary role of pilot enterprises and chemical industry parks. Sixth, we advocate "responsible care" and establish a good image of China's oil and chemical industry.
At the meeting, the leaders of the National Development and Reform Commission and the State Environmental Protection Administration introduced the environmental protection situation in China. They visited Xinjiang Tianye Group Company and PetroChina Dushanzi Petrochemical Branch; 15 key petroleum and chemical companies and chemical industry parks jointly issued a strong Promote the implementation of pollution reduction initiatives.
Oil and Chemical Reduction Experience Exchange Meeting Held
Chairman Li Yongwu put forward six opinions sponsored by China Petroleum and Chemical Industry Association and China National Chemical Industry Environmental Protection Association, the Eighth Division of the Xinjiang Production and Construction Corps, the People's Government of Shihezi City, and Xinjiang Tianye Group's experience in pollution reduction in the national oil and chemical industry. The exchange meeting was held in Shihezi City, Xinjiang on September 18-19. More than 200 representatives from key oil and chemical companies, professional associations, provinces (autonomous regions, municipalities), environmental protection bureaus, economic and trade commissions, and development and reform commissions from across the country attended the conference. The commander of the Xinjiang Construction Corps, Hua Shifei, is the leader of the National Development and Reform Commission and the State Environmental Protection Administration. Li Yongwu, president of the China Petroleum and Chemical Industry Association, attended the meeting and delivered a speech.
