Hefei Zhongya Environmental Protection Technology Co., Ltd. took the lead in successfully developing the wide electrostatic precipitator and applying it in dust treatment in cement production in China. In 1996, the company acquired internationally-advanced electrostatic precipitator technology from EE Company USA

FGM (M) Series Explosion-proof Bag Filter is the scientific achievement and representative product of our company. It received the bronze medal of Technology Progress of the State Administration of Building Materials Industry for this achievement. With fire-proof and explosion-proof design, this product is widely used for flammable and explosive dust and pulverized coal collection. Dust proof sheet on dust-collecting cross section, safety valve and a large hopper valley angle ensures long term and high efficiency operation without any dust deposition. With automatically PLC control and high pressure jet pulse technology, it is able to handle smoke with concentration up to 800g/Nm3 one time. Emission concentration is lower than 30mg/Nm3. The compressive strength of the casing can be up to 14000Pa.

FGM Series Plenum-pulse Bag Filter integrates advantages of split-chamber backflow dust collector and jet-pulse dust collector. It is designed with a big unit air flow and can work efficiently. It can be used directly for highly dense gas up to 1300g/Nm3, and the density drops to lower than 30g/Nm3 after treatment. Different filter materials are used, depending on different working conditions. FGM Series Plenum-pulse Bag Filter can be divided into more than 10 models from series 32 to series 192. Maximum capacity can be up to 1000000m3/h. When filmed filter bags are taken into use and system resistance is lower than 1700 Pa, it can meet higher discharge standards. With high-quality pulse valve (more than 1 million times guarantee) and high tech PLC (Programmable Logic Controller) adopted, the whole process is convenient and the maintenance is simple.

KDMC Series Low-resistance Bag Filter for GGBS Grinding System is designed to satisfy the characteristics of the slag powder (high moisture, high concentration, fine dust particle, dust hard to be peeled). Armed with two patent technologies (patent number: 200710019735.9 and 200710020183.3), it can maximize dust inertia settlement, reduce load of dust, improve cleaning efficiency, reduce adsorption capacity of filter dust and reduce resistance of bag dust. Compared to other bag filters of the same specifications, this product has the following advantages: 15% - 40% less power consumption for fans; emission concentration <10mg/Nm3; normal service life as long as 3 to 4 years.
