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

Embodiment 1

[0025] Embodiment one, refer to the description attached figure 1 - 8. A double-duct bag filter, including an air inlet and an outlet arranged in the middle above the frame, ash hoppers and dust removal chambers connected to it symmetrically arranged on both sides of the inlet, and an outlet The cleaning air chamber connected to the dust removal air chamber and the air outlet channel is set at the upper end of the upper end, and is characterized in that: the air outlet channel and the air inlet channel are separated by a middle lateral During the test, the dust-laden gas pipe and the middle bypass air duct are connected, and the dust-laden gas passes through and is discharged directly from the middle bypass air duct, replacing the existing bypass air duct surrounding the outside of the dust collector. The upper end of the ash hopper is fixedly connected with the frame, and the dust removal air chamber is connected to the upper end of the ash fall hopper and communicated with ...

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...
