With the development of industry, environmental pollution has become more and more serious, especially the combustion of various industrial kilns and boilers, which are important sources of pollutants transporting pollutants to the atmosphere. Because air pollution has caused great harm to the earth environment for human existence, the global control of air pollution has become more and more stringent, and emission standards have been continuously improved. At present, the flue gas desulfurization, denitrification and dust removal system in the industry is a simple combination of independent systems. It has independent equipment and control systems. The entire set of desulfurization, denitrification and dust removal system has huge hardware and software and occupies space, and it also needs to be at the end Adding de-whitening equipment has disadvantages such as large investment, difficult management, low efficiency, and high operating cost. Therefore, our company designed and developed a modular exhaust gas treatment equipment for fiberglass composite pipe dry method integration and put it into actual engineering projects. It has obtained good environmental benefits and won the honor of "the first set" in Zhejiang Province and the key scientific and technological project of Tongxiang City. .
