Transformation of Electric Bag Composite Dust Collector HST Foundary

The transformation of the electric bag composite dust collector is based on the original electric bag composite dust collector, and aims to improve the efficiency of the discharge concentration at the outlet of the dust collector. By analyzing the material of the filter bag, improving the uniform distribution of the overall air flow, studying the filter bag mouth and bypass sealing The feasibility and specific measures of changing the filter bag of the electric bag filter to improve efficiency are proposed.

The electric bag composite dust collector is composed of two units, namely an electric dust removal unit and a bag dust removal unit. Generally, an electric field is arranged in the electrostatic precipitator. This kind of electric-bag composite type dust collector has a front and back bag, that is, the electric dust collector can collect 80% -90% of dust in the flue gas, which greatly reduces the concentration of entering the filter bag, reduces the resistance of the filter bag, and cleans the bag. The ash cycle is increased, thereby extending the life of the bag. It has the advantages of the bag filter is not sensitive to coal types, and the fine dust collection efficiency is high (99.9%). It can ensure that it can reach the emission standard of 50mg / m3.

The working process of the electric bag composite dust collector is that after the dust-containing flue gas enters the dust collector, about 80% -90% of the dust in the flue gas is collected in the electrostatic precipitator, and the remaining 10% -20% of the fine dust is collected by the level. The flow is folded to the lower part of the electric field, and then moves from the bottom to the top, and enters the bag dust collection chamber. The dusty flue gas passes through the outer surface of the filter bag, and the dust is trapped on the outer surface of the filter bag. The clean gas enters the upper clean room from the inner cavity of the filter bag, and is discharged from the chimney to the atmosphere through the induced fan.
