  central dust collection system supplier refers to the method of blowing compressed air to remove the dust attached to the filter medium (cloth bag or filter cartridge). According to the size of the pulse dust collector may have several groups of pulse valves, controlled by the pulse controller or PLC, each time open a set of pulse valves to remove the dust of the part of the bag or filter cartridge controlled by it, while the other bag or filter cartridge works normally, after a period of time, the next set of pulse valves are opened, and the next part of the dust collector is cleaned by the ash bucket, the upper box, the middle box, the lower box and other parts. The upper, middle and lower boxes are divided into chambers. When working, the dust-containing gas enters the ash hopper from the inlet air duct, the coarse dust particles directly fall into the bottom of the ash hopper, the fine dust particles enter the middle and lower box with the airflow turning point, the dust accumulation is attached to the outer surface of the filter bag, the filtered gas enters the upper box to the clean gas collection tube - exhaust air duct, and is discharged to the atmosphere by the exhaust fan.

  What causes the central dust collection system supplier to run poorly? Here is a detailed introduction for you:

  First, the dust collector has air leakage phenomenon: because the dust collector has air leakage phenomenon, a large number of cold air from the outside is sucked into the dust collector, so that the local air temperature of the dust collector drops sharply, and the water in the air is precipitated, resulting in condensation. There are many reasons for the dust collector air leakage, there is leakage caused by the dust collector shell in the production and installation process, there is leakage caused by the discharge device seal is not strict, there is leakage caused by the non-standard pipe welding phenomenon in the installation process, there is leakage caused by the dust collector and the non-standard pipe flange joint seal is not strict caused by air leakage and so on.

  Second, the smoke temperature is not high: when the temperature of the flue gas treated by the dust collector is close to or not higher than the dew point temperature, condensation will also occur.

  Third, the dust collector shell has no heat insulation measures or poor effect: the shell of the dust collector generally uses a steel plate structure, and the thermal conductivity of the steel plate is very large, when the temperature of the outside air and the dust collector internal gas temperature to form a large temperature difference, the dust collector shell will produce condensation. If the shell of the dust collector does not take heat preservation measures, or although the heat preservation measures are taken, the effect is not good, the condensation phenomenon of the dust collector is inevitable.

  Fourth, the pulse blowing gas temperature is not too high: the dust collector uses compressed air in the process of pulse blowing ash, and the compressed air itself is saturated air with relative humidity. Because its pressure is greater than atmospheric pressure, the dew point converted to atmospheric pressure is not higher than the ambient dew point, and there is a tendency to break away from condensation.

  5. The moisture content in the flue gas is too high: when the moisture content in the treated flue gas is too high, the supersaturated water precipitates, resulting in condensation. This phenomenon is prominent on the kiln tail dust collector of cement dry normal line, because the flue gas of cement dry normal line kiln tail is generally cooled and tempered by humidification tower, when the water sprayed is too large, resulting in the phenomenon of supersaturation of water in the flue gas, condensation will occur.
