Wet electrostatic precipitator dust gas is closely contact with liquid, water and particle inertia collision or using the see water and full thick cloud of dust and other disseminated capture particles or make particles increases in solid container or the installation of water and dust separation effect. The following is about the wet electrostatic precipitator in the use of the often touched achievements, and solutions.
1. The dust gas temperature is too high, and the system did not adopt any heat preservation heat insulation measures, make the dust in the pipe, dust collector into the external environment of temperature difference is bigger, the heat exchange process a temporary precipitation water vapor condensation, increase the humidity and dust sticky, measures should be adopted heat preservation heat insulation.
2. The dry system parameters of the pulse blast system are improperly set and the dust removal effect of the dust collector is poor. For example, the duration of pulse blast of filter bag is too long, the width of pulse blast is too short, and the pressure of tight atmosphere is too low. The parameters of the system should be reset.
3. The characteristics of filter bag materials and dust do not match, which constitutes part of stomatal asphyxiation. For dust with high concentration, small particle size, high humidity and high viscosity, film - coated filter materials should be selected.
4. If the dust concentration of the system is too high and the filter material filtering wind speed is high, the pressure difference of the filter bag is too high. The dust load of bag-type dust precipitator and the filtration speed of filter material should be reduced, that is, the filtration area should be increased, and the filtration speed of filter material should be reduced.
6. Check the worn environment of the filter bag regularly, and deal with the phenomenon of bag breaking in a timely manner.
In normal days, the dust precipitator is controlled by negative pressure. Air leakage can easily form a large influx of internal atmosphere.
1. Influence the firmness of kiln system. A large amount of air is injected by air leakage, and the effective air volume of the exhaust fan kiln system is decreased, which affects the output.
2. Equipment leakage. The dust will be sprayed out at high speed through the process disclosure point under the influence of ash removal power.
3. Increase the running resistance. The dust collector was originally operated at negative pressure, and the leakage wind was positive pressure gas, which greatly increased the running resistance.
4. Condensation inside the equipment and corrosion of the equipment. A large number of cold atmosphere enters to reduce the operating temperature, especially in the cold summer and rainy season, forming paste bags, condensation, depravity equipment, which affects the abnormal use of dust collectors.
