Chamber dust collector

Abstract

Provided are a compartmentalized dust remover and a dust removing process using same. The compartmentalized dust remover comprises support legs (1), a damper valve (2), an ash hopper (3), a middle enclosure (4), a converging bellow (5), an upper enclosure (6), an ash clearing system, a ladder (8), a guardrail (9), a dust collecting filter bag (10), a bag cage (11), a poppet valve (12), a ceiling (13), partition plates (14), an air inlet, and an air outlet. The upper enclosure (6) and the middle enclosure (4) of the dust remover are rectangular. Multiple compartments are formed respectively within the upper enclosure (6) and the middle enclosure (4) by means of the partition plates (14). The ceiling (13) is provided with several ceiling holes. A filter bag component consisting of the filter bag (10) and the bag cage (11) is connected below the ceiling holes. The air inlet and the air outlet of the dust remover are provided with pressure sensors.

Description

technical field [0001] The invention relates to a chamber-divided dust collector, in particular to a dust collector with automatic switching between off-line and on-line cleaning. Background technique [0002] Dust collector is a common device used to eliminate dust in dusty airflow in environmental protection engineering and labor protection work. There are many types of bag filter at home and abroad, such as pulse bag filter, LFS reverse blowing double-layer bag filter and so on. During the working process of the bag filter, dust will accumulate on the dust bag after a period of time, which will cause problems such as excessive resistance and reduced dust removal efficiency. Therefore, it is necessary to regularly clean the dust bag. For example, Chinese patent CN2167765Y discloses a bag-type dust collector, which utilizes valve control to remove accumulated dust in the bag by adopting the method of reversing the air flow in each chamber and shaking off the dust by the ba...

Problems solved by technology

However, when a chamber of the dust collector is off-line for cleaning dust, the valve of this chamber is closed, and the filter bag does not participate in dust collection, which will increase the filtering wind speed in the entire dust collector, and accelerate the wear of the filter bag. The system resistance will also suddenly become the largest, resulting in unstable air flow, especially when the dust collector has less than 5 chambers.

In order to achieve higher dust collection efficiency in this way of dust removal, it often requires a large product space, which results in excessive product cost.
