Device and method for protecting filter bag of bag type dust collector

Abstract

The invention discloses a device and a method for protecting a filter bag of a bag type dust collector, and belongs to the technical field of bag type dust collectors. The bag type dust collector filter bag protection device comprises a dust removal air bellow, an air inlet is formed in one end of the dust removal air bellow, and an air outlet is formed in the other end of the dust removal air bellow. In order to solve the problems that an existing bag type dust collector basically adopts back flushing type circulating cleaning, tiny dust on a cloth bag falls down through back flushing of gas, but the structure of the cloth bag can be affected by airflow pressure generated by back flushing, the gas enters a mixed gas cavity from an air inlet, and the mixed gas cavity is communicated with the air inlet. When flowing in the mixed gas cavity, the mixed gas can drive the vibration blades to vibrate, the vibration can be downwards transmitted to the elastic sheet ribs, tiny powder attached to a cloth bag can be shaken off through the vibration generated by the elastic sheet ribs, traditional gas back flushing is replaced, the cloth bag is circularly cleaned, and damage to the cloth bag is avoided.

Description

technical field [0001] The invention relates to the technical field of bag-type dust collectors, in particular to a bag-type dust collector filter bag protection device and a method thereof. Background technique [0002] A bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of woven filter cloth or non-woven felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag filter After the filter, the dust with large particles and heavy specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is blocked and the gas is purified. [0003] The existing bag filter basically adopts the back-flushing cycle cleaning, which uses the back-flushing of gas to drop the fine dust on the bag, but the air pressure generated by the back-flushing may ...

Problems solved by technology

[0003] The existing bag-type dust collector basically adopts the back-blowing cycle cleaning, which uses the gas back-blowing to drop the fine dust on the bag, but the airflow pressure generated by the back-blowing may affect the structure of the bag itself; therefore , does not meet the existing needs, we propose a bag filter bag protection device and its method
