On December 26th, the Ministry of Industry and Information Technology publicized the list of the first batch of companies that met the “Yellow phosphorus industry access requirementsâ€, among which 45 companies including Hubei Xingfa Group were among them. People in the industry believe that this move is conducive to promoting the upgrading of the national yellow phosphorus industrial structure, regulating the order of market competition, controlling the excessive growth of the industry, and stimulating the concentration of capital, technology, resources, etc., on key regions and enterprises, and accelerating the elimination process and suppression of backward production capacity. Low level of repeated construction. The Ministry of Industry and Information Technology publicized the list of the first batch of short-listed companies in accordance with the requirements of the Yellow Phosphorus Industry Access Requirements and the Interim Measures for the Management of Yellow Phosphorus Production Enterprises Announcement, and the relevant provincial industry authorities and provincial environmental protection, quality inspection, and safety supervision departments. Verify the recommendation, according to the review opinions of the experts on the company's application materials, as well as on-site spot checks and review of some companies, and eventually publicize the list of the first batch of companies that meet the “Yellow phosphorus industry access requirementsâ€. Phosphate rock is the main raw material for the production of yellow phosphorus. According to the data released by the US Geological Survey, China's phosphate reserves are ranked second in the world. At present, China has only 21.11 billion tons of reserves of preserved phosphate rock resources, with an average grade of 17%, of which only half of the rich minerals with a grade of more than 30%. Due to the low ore grade and technical backwardness, the average recovery rate of domestic phosphate rock is only 60%, which is lower than the level of more than 95% in the United States, North Africa and other countries and regions. The publicity companies are concentrated in four provinces, including 9 in Hubei, 3 in Sichuan, 11 in Guizhou, and 22 in Yunnan. The publicity period ends on December 26, 2011 and ends on January 17, 2012.
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.
