Electric change bag dust removal is imperative

Core Tip: Reducing fine particulate matter is the key to controlling atmospheric soot emissions from the cement industry. Active control from the source of sewage is the fundamental method to cope with the dual pressures of enterprise survival and ecological protection. Among them, the electric change bag is one of the current * effective technical measures.

Active control from the source of sewage is the fundamental method to cope with the dual pressures of enterprise survival and ecological protection.

The industry believes that bag dust removal technology instead of electric dust removal is the path of dust removal in the cement industry. Not only that, bag dust removal will provide technical support for * strict environmental standards, and is the main force to reduce atmospheric pollutant emissions.


Before and after the heavy snow festival, the haze weather once again enveloped many parts of China. In the face of the increasingly smoggy weather, how should people deal with it? How do you get rid of the hats of big polluters?


Dust removal is a priority


In 2012, the world's total cement output was about 3.9 billion tons, and China's cement production and sales reached 2.184 billion tons, accounting for 55% of the world total. As of the end of last year, there were 1,637 clinker production lines nationwide, including 1,257 clinker production lines with a daily output of over 2,000 tons. After years of transformation and development, the cement industry has achieved good results in eliminating backward production capacity, pollutant treatment, and waste heat power generation.


Jiang Minglin, a counselor of the State Council Counselor and former deputy director of the State Building Materials Bureau, believes that although the cement industry is at the forefront of the industrial sector in terms of integration, we should see that the cement industry is still a high-consumption and high-emissions industry. The process of production is determined by the process. According to 2010 statistics, the total energy consumption of the cement industry accounts for 5% of the country's total energy consumption, and dust accounts for 31.7% of the country's total industrial production emissions. Such huge energy consumption and pollutant emissions are given to the national economy. The sustainable development and ecological environment bring great pressure. Vigorously promoting scientific and technological innovation and promoting technological progress in production technology and equipment are fundamental to doing a good job in cement environmental protection.


The national smog weather has pushed the pollution problem of cement companies to the cusp of public opinion. "For many years, the cement industry has always been synonymous with the 'dirty mess' in the eyes of ordinary people. The smoggy weather this year has made the image of the cement industry even worse." Gao Changming, consultant of the China Cement Association, pointed out that "China's unit land area emissions The amount of cement soot is 8.45 times the world average, and it is also the highest in the national industrial industry."


Gao Changming once introduced a “two 2.5%” experience: “The dust generated in the cement plant production process accounts for 2.5% of the clinker production, and the weight lost during the transportation process accounts for 2.5% of the clinker production. The development of concrete and the increase in cement bulk rate, the latter data has declined, but the previous 2.5% is still ubiquitous."
