Major equipment at home and abroad for dust control inertial dust collector, cyclone, cartridge filter, bag filter, electrostatic precipitators, water film dust and so on. Water film dust, shower wet dust precipitator for air box pulse dust collector, which is suitable for high temperature and dust, but dust removal efficiency is not high, the operating environment is poor pulse dust collector, is not suitable for efficient dust removal systems; inertial dust , cyclone effect of coarse dust particles collect better, but is powerless to fine dust. Environmental protection department calculations, if the province more than 135,000 kilowatts of coal-fired units are ultra-low emissions, sulfur dioxide, nitrogen oxides and dust emissions further reduction of 155,000 tons per year, 46,000 tons and 20,000 tons. Strict elimination of backward production capacity. All included in this year and eliminate backward production overcapacity task of the project, the relevant line from October halted; all located in the city's main city of heavily polluting enterprises, must come up with a clear environmental relocation, renovation plans. Air box pulse dust collector, three wins and environmental protection of the cattle (certified), ESP is provided by Environmental Science and Technology Co., Ltd. Henan three wins. Henan three wins Environmental Technology Limited (www.hnsshbkj.com) (www.hnsshbkj.com) is a leader in Zhengzhou, dust removal equipment, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In three wins environmental leadership with the staff warmly welcome all inquiries negotiations to create three wins and a better future for environmental protection.
