Double-air-duct cloth bag-type dust remover

Abstract

The invention relates to a double-air-duct cloth bag-type dust remover. A middle bypass air duct is arranged between an air inlet duct and an air outlet duct of the dust remover through an inclined plate, is positioned in the dust remover and penetrates through the dust remover, so that the arrangement mode that an existing bypass air duct surrounds the outer side of equipment is replaced, the size of the whole machine is reduced, the occupied space of the equipment is reduced, materials and labor are saved, and the cost is high; a cloth bag is arranged on the outer side of a cloth bag supportin a sleeving mode. During dust removal, the bracket can support the cloth bag; the poor dust removal effect caused by cloth bag deformation is avoided; a dust removing mechanism is arranged at the upper end of a cloth bag assembly, an air tank of the dust removing mechanism provides high-pressure air for a blowing pipe, the interior of the cloth bag can be blown at any time, dust covering and adhering to the surface of the cloth bag is blown away, the filtering and dust removing effect of the cloth bag is improved, and the dust removing mode is high in automation degree and efficiency.

Description

technical field [0001] The invention relates to the technical field, in particular to a bag filter with double air ducts. Background technique [0002] The bag filter is the most commonly used dust removal device at present. Its working principle is: the coarse particles in the dusty gas fall into the ash hopper through the flue, and the fine particles in the dusty gas are filtered through the bag, so as to realize the dedusting of the dusty gas. The conventional bag filter is mainly composed of an ash hopper, a box body, a cleaning room, a cloth bag, a dust cleaning device, an air inlet duct, and an air outlet duct. Its working principle is that the dust-laden gas enters the box from the air inlet of the dust collector, and after being filtered by the cloth bag in the box, the clean gas enters the air outlet through the clean room and is discharged, and the dust falls into the ash hopper. [0003] However, after the dust collector works for a period of time, the dust cove...

Problems solved by technology

[0003] However, after the dust collector works for a period of time, the dust covered and bonded on the surface of the bag gradually increases, resulting in an increase in the resistance of the bag and weakening the filter and dust removal effect of the bag. Therefore, a dust cleaning device is required to remove the dust covered on the surface of the bag before the dust collector can work again. , the existing cleaning device has complex structure and low degree of automation. It needs to be shut down and manually assisted to complete the cleaning operation, and the cleaning effect is not good.

[0004] In addition, the existing dust collector equipment needs to be tested after it has just been installed or after a fault has been repaired. Therefore, a bypass air duct surrounding the outside of the equipment is drawn from the equipment. This bypass air duct increases the safety of the whole machine. The volume increases the floor space of the equipment, wastes waste and high cost
