centralized dust collection system The centralized dust collection system consists of five parts: clean air box, dust air box, ash hopper, injection equipment and support. Clean air box part, this part is equipped with a blow pipe, clean air part has a clean air outlet, in front of the access door, open the access door, can easily replace any filter bag, dust gas part, dust gas is located in the upper part of the air box, the box is equipped with a filter bag, ash bucket part, dust gas into the dust box, clean air empty filter bag to clean air box. The dust will settle into the ash hopper, and the settling direction is consistent with the airflow direction, which is conducive to the dust settlement. There is a partition between the clean air box and the dust air box. The size of the filter bag is a rectangular flat filter bag with a length of 1200mm, a width of 480mm and a thickness of 26mm. Reverse blower equipment, installed under the clean air box, including air bag, pulse valve, pulse controller, etc.
How should the problem of centralized dust collection system be resolved? Below, give you a detailed introduction:
1. Short cleaning cycle: short cleaning cycle is conducive to timely cleaning of lime dust on the surface of the bag and reducing the possibility of bonding.
Two, the lime powder bag dust collector set stable bypass pipeline: When the relative humidity of the air increases, the dusty air entering the dust removal system is easy to dew. In order to avoid the water gas entering the centralized dust collection system and binding the filter material, stable bypass pipeline should be set up. At this time, the bag type dust collector can be avoided, so that the dusty air only passes through a layer of cyclone dust collector, and then discharged into the atmosphere. The above can be controlled automatically.
3. Use dust bag with caution: smooth dust bag that is not easy to stick to the lake should be selected, such as smooth polyester filter material 729, needle felt dust bag, high temperature dust collector bag, etc.
Four, low filter wind speed: the filter wind speed is good, will force the fine lime dust into the zigzag microhole blockage, reverse blowing ash ineffective, long-term stay in the bag inside and form adhesive blockage filter hole. And the use of low filter wind speed, can avoid the above problems.
Five, enough dust cleaning back blowing pressure: with the back blow air cleaning, the lime dust can be cleaned out into the filter material, and enough pressure, is conducive to all the dust cleaning filter material.
centralized dust collection system is composed of box body, filter bag room and lower dust hopper. The main difference between the precoated centralized dust collection system and the old-fashioned centralized dust collection system is that the centralized dust collection system is equipped with active filter feeding equipment. Before filtration, the filter aid is actively coated on the surface of the filter bag by the filter aid feeding equipment, so that the inner surface of the filter bag constitutes an outstanding pre-coating. The precoating is composed of a filter aid attachment layer and a filter aid layer. In addition, the filter aid can be added to the pipe before the dust collector to increase the reaction time between the filter aid and the pollutant. During filtration, the dusty gas with gas and liquid phase pollution enters the pre-dust collector to remove the coarse dust. The dust not captured and collected enters the filter bag room of the pre-coated centralized dust collection system with the air flow. When passing through the filter bag, the dust is trapped on the precoating on the inner surface of the filter bag, and the purified gas is discharged by the fan.
