How to prevent leakage of pulse filter bag ?

Precipitator dust leakage will not only result in decreased operating efficiency, but also affect the life of the filter bag, filter dryer because it will lead to leakage and condensation dust bag, so that dust is not working to solve such problems, We will optimize precipitator design and installation, to strengthen the bag filter seal. 1. Optimization of long bag pulse bag filter design and installation Pulse bag filter bulky, in order to facilitate transport, usually the disintegration of production, split shipping, assembled on site and other means. Improper installation site could easily lead to dislocation of the device up and down, forced to install easy to produce locally deformed weld uneven; the device to put into operation, under the combined effects of wind turbine power, cleaning power and thermal stress, said defects easily form highly stress concentrated, resulting in partial cracking, resulting in equipment leakage. Precipitator design, should be considered in addition to the apparatus body has sufficient strength, rigidity outside, but also optimize the installation program, try to install the cumulative reduction of errors, improve installation quality. 2. Strengthening the rotary kiln sealing long bag pulse bag filter dust removal system Strengthening Manhole Sealing: Manhole covers shall be designed to meet the strength and stiffness requirements, the production of doors and door frames shall be smooth cover using seal assembly to seal the door with pressed compacts. Common seal structure has a “U” and “Y” type. Strengthening anti-hair-valve seal: anti-hair bag filter cleaning energy from the cleaning fan, in order to protect its motor, to avoid frequent open, general cleaning fan is set to normally open state, when reverse air valve closed lax, generated when the cleaning fan work the positive pressure of gas in the cleaning of non-continuous period of blown bag house, seriously interfere with the normal work of the filter dust collector. Mainly as follows: continuing work due to leakage caused by increased resistance; when cleaning, because several other anti-hair valve leakage, energy dispersion, so that the bag is cleaning chamber cleaning energy shortage, the impact of the cleaning effect. In order to improve operational efficiency, we recommended for anti-hair seal valve seal. Strengthening sealed dust removal system: to prevent air leakage sealing must also be strengthened under the rigid impeller feeder, inlet and outlet valves, piping and transportation equipment, inspection doors and other equipment, to reduce and eliminate leakage phenomenon. Such as: higher precision, shell and all piping connections shall be continuous welding, without leakage, sealing off the phenomenon; each valve, cinder, ash back to the device connection plus gaskets, fasteners and connections are secure and can not be tainted gas phenomenon. Precipitator machining accuracy should meet the JC / T530-2007 requirements. 3. Reasonable selection pulse pressure long bag pulse jet bag filter Pulse jet bag filter cleaning energy from the compressed air, compressed air is injected into the gas under positive pressure, to ensure the cleaning effect of the premise, in order to protect the bag and efficient operation of the gas pressure should not be too large, instantaneous compression cleaning air is injected into the same device can be regarded as leakage, injection pressure, the higher the equipment running resistance, recommendations based on conditions reasonable selection of pulse jet pressure, the recommended values: 0.20MPa ~ 0.25MPa.
