Mainly engaged in environmental protection, environmental engineering design, environmental protection equipment design and manufacturing, environmental protection engineering. In order to meet the needs of air pollution control, the company's technical personnel in the international electrostatic dust removal, Bob and the director of the national electric dust removal Committee, Wang Liqian, to the original application in chemical, smelting and other industries wet electrostatic precipitator to optimize the transformation, play its fine / viscous / high specific resistance dust, aerosol, fine particles, etc., the ideal of a deep purification, can achieve "near zero emissions" (lower than the gas boiler emissions standards) governance effect. The technology and equipment have been declared national invention patents. At present, the company has built an annual production capacity of 100000 carbon fiber composite (CFRP) anode tubes and related electrical equipment production base. Construction of Tangshan Sanyou thermoelectric Co., Ltd. 3*240T/h circulating fluidized bed boiler flue gas emission reduction comprehensive governance projects has to put into operation in December 2014 and smoothly through the State Environmental Protection Department of the inspection and acceptance.
