long baghouse

     Baghouse(BH, B/H) or bag filter(BF) or fabric filter(FF)

Theories:

      Based on the overseas advanced technology, our team develops this new system on our own. This system synthesizes the advantages of reverse air (R/A) and pulse jet baghouses and overcomes their flaws—low collection efficiency for the compartmentalized R/A baghouse, and the redeposit of dust for the jet baghouse. Our system requires less space, and is widely used in cement plants, steel mills, power plants, etc.

Features:

     1. Our system uses long, cylindrical bags made of fabric as a filter medium. A compressed air is injected on specific points to remove the dust cake.

     2. Our system has the optimized cleaning method, uniform distribution of gas stream, low resistance to air flow, detailed design. Therefore, it can operate stably for a long term.

     3. Our system can control emission concentration under 10mg/Nm3. It occupies small area, operates stably, having lower bag wear, high collection efficiency and convenient maintenance.

Wet electrostatic precipitator (WESP or wet ESP)

Theories:

  Traditional wet electrostatic precipitator is redesigned according to the properties of flue gas in our country. The brand new wet ESP works the same way as the dry ESP. The difference is that liquid resin is used to clean the plates and electrodes. The system can also catch heavy metal particles and adapt to various working conditions (like coal mine). Because of its high dust collection efficiency, it is widely used, especially after wet desulphurization equipment.

Features:

     1.Emission concentration is controlled under 10 mg/Nm3. And no re-entrain dust will be formed.

     2.Plates and electrodes are washed by liquid, which makes it easier to collect dust with high resistivity.

     3.The PM2.5 particles and aerosol collection efficiency is 90%. The mercury and other heavy metal collection efficiency is 90%, too. Consequently, the color of the smoke turns lighter dramatically.

     4.The SO2 collection efficiency is over 90%. The water vapor collection efficiency is over 75%. Therefore, the common problems in wet desulphurization, the gypsum rain and plume of blue haze, are avoided.

     5.The positive electrode is plate-style, which can keep a thin water film on it. And the water mist is easy to be collected on the plate-style electrode.

     6.The parts contacting with smoke are made from anti-corrosion materials, improving the reliability of the system.
