Stepping?negative pressure compartment pulse reverse?suction?ash removal deduster?

Abstract

The invention relates to a stepping?negative pressure?compartment pulse reverse?suction?ash removal deduster,?which?includes a bottom?platform, an air inlet?pipe,?a?pneumatic ash conveying?pipe,?ash buckets, a filter?bag?chamber,?a?clean?air chamber, a top cover, a clean?air outlet,?pulse valves, an air?pocket,?blowing pipes, a tubesheet, a double-shaft?direct current motor, rollers, a guide?rail,?three-way valves, and filter?bags. The?filter?bag?chamber is provided with a compartment baffle, and the clean air chamber is a communicated chamber. The?air inlet?pipe is disposed between the two ash buckets, the three-way valves are mounted at the outlets of the ash buckets, and the pneumatic ash conveying?pipe also serves as a reverse?suction pipe. The deduster is only provided with one air?pocket, two ends of which are respectively provided with two pulse valves and two corresponding blowing pipes. A walking mechanism composed of the?double-shaft?direct current motor, the rollers and the guide rail is disposed under the air?pocket. The air?pocket assembly and its walking mechanism are disposed in the clean air chamber. A PLC?program control?cabinet is employed to control the synchronous action of the three-way valves and the pulse valves, and walking of the?double-shaft?direct current motor according to the line space of the?filter?bags. The deduster provided in the invention has the advantages of simpler structure, reduced cost, more convenient installation and maintenance, low running cost, and reduced failure rate.

Description

technical field [0001] The invention relates to an industrial flue gas dust collector in environmental protection equipment, in particular to a step-by-step negative pressure compartment pulse reverse suction air dust removal dust collector. Background technique [0002] At present, the domestic long-bag low-pressure pulse dust collector is the most advanced flue gas dust removal equipment. Widely used in metallurgy, building materials, electric power, chemical industry and other industries. However, no matter whether the dust collector adopts online or offline dust removal, there is secondary adsorption of dust. Each chamber is provided with an air bag, and each air bag is provided with 10-16 pulse valves and 10-16 blowing pipes. A large long-bag low-pressure pulse dust collector has dozens or hundreds of pulse valves and dozens or hundreds of blowing pipes. Not only the steel consumption is high and the investment is large, but also the manufacturing, installation, main...

AI Technical Summary

Problems solved by technology

Not only the steel consumption is high, the investment is large, but also the manufacturing, installation, maintenance, and bag replacement are difficult, expensive, high operating costs, and equipment failures

In response to the above problems, our company has developed a "stepping low-pressure long bag pulse dust collector" applied to the positive pressure pulse bag dust removal system, and applied for a patent (patent number 201020529525.1). Due to the positive pressure system, the induced draft fan enters the dust collector The dust in the flue gas of the induced draft fan, especially the high-concentration dust, seriously wears out the fan and shortens the life of the fan
