I. product introduction Cloth bag dust remover clear ash system USES a high frequency vibration and the blowing, and the reverse blowing by a specially designed electric cylinder to drive the 3-way valve (pos. No. To do this, the action of electric cylinder controlled by a set of automatic control system, greatly save the necessary auxiliary equipment investment, reduce the power consumption and operating cost of equipment. 2. Working principle As the working time increases, the thickness of the dust layer on the inner wall of the filter bag increases gradually, and the resistance gradually rises to 80-120mm horizontal column, which can be seen from the u-type pressure gauge. The main valve plate of the electric three-way valve is closed when the electric cylinder is actuated. The equipment also has the advantages of stable and reliable performance, long filter life, high dust removal efficiency and convenient maintenance. Gas from the air inlet pipe to ash hopper, and then upward through the filter bag after purification of the casing, by electric three-way valve to open the main valve plate to the trachea, then through tracheal gas centrifugal fan, chimney discharged into the atmosphere. The dust precipitator is widely used in ceramics, metallurgy, casting, light industry, food, building materials, chemical industry and other industries.
