Bin top type pulse back-blowing dust remover

Abstract

The invention provides a bin top type pulse back-blowing dust remover. The bin top type pulse back-blowing dust remover comprises a shell, a filter chamber, an air purification chamber, a security and protection system and an ash removal system, in the shell structure, the upper end and the lower end of a dust remover barrel are connected with an end socket and a stock bin through a top large flange and a bottom large flange, and a filtering chamber for filtering dust and a gas purifying chamber for storing gas are separated in the barrel through a perforated plate; the security and protection system comprises a rupture disk assembly and a differential pressure transmitter, is arranged at the bottom of the barrel and is used for preventing equipment burst and monitoring differential pressure; the ash removal system comprises a pulse control box, an air bag, a pulse valve, a filter bag and a blowing pipe, the pulse control box and the air bag are located on the two sides of the barrel, the filter bag and the air bag are connected through the blowing pipe, the pulse valve is arranged on the blowing pipe, and the pulse control box is used for controlling the pulse valve to feed compressed air into the filter bag for ash removal. The invention further provides a dust removal method and an ash removal method of the bin top type pulse back-blowing dust remover, the problem of gas dust removal in a limited operation space is solved, and recovery of powdery materials after dust removal is achieved.

Description

technical field [0001] The invention relates to the field of dust collectors, in particular to a bunker-top pulse blowback dust collector. Background technique [0002] At present, petrochemical companies mostly use traditional bag-type dust collectors to filter the dust-laden airflow inside the end pipeline of the air delivery system and at the dust point. However, the space on the petrochemical operation site is limited. Discharge management indicators, the larger the size of the internal space of the dust collector, the easier it is to form a charged "charge cloud", causing an ignitable discharge. The traditional bag filter is bulky and expensive to build, and the larger dust collector is prone to form a charged cloud. "Charge cloud" has potential safety hazards. [0003] At the same time, in the production process of existing petrochemical pellet products such as polyolefin and polyester products, a certain amount of fine powder appears in the product due to reasons suc...

[0002] At present, petrochemical companies mostly use traditional bag-type dust collectors to filter the dust-laden airflow inside the end pipeline of the air delivery system and at the dust point. However, the space on the petrochemical operation site is limited. Discharge management indicators, the larger the size of the internal space of the dust collector, the easier it is to form a charged "charge cloud", causing an ignitable discharge. The traditional bag filter is bulky and expensive to build, and the larger dust collector is prone to form a charged cloud. "Charge cloud", a potential safety hazard

[0003] At the same time, in the production process of existing petrochemical pellet products such as polyolefin and polyester products, a certain amount of fine powder appears in the product due to reasons such as particle tailing, pelletizing knife gap, template hole blocking, etc., which seriously affects the reputation of the product And the quality of downstream products, such as the fine powder entrained in bottle-grade polyester chips and pellets will cause crystal points to appear when users blow the bottle. Realize the gas dust removal and dust recovery at the end of the pneumatic conveying system for polyolefin, polyester and other powder materials
