Device for filtering dust

Abstract

The invention discloses a device for filtering dust. The device for filtering dust comprises a box; a separating plate is fixed in the box; the interior of the box is divided into an air discharging cabin and an air feeding cabin from top to bottom by the separating plate; the device for filtering dust further comprises a first annular cloth bag and a second annular cloth bag; the second annular cloth bag is coaxially arranged with the first annular cloth bag and is located in the first annular cloth bag; the lower part of the first annular cloth bag and the lower part of the second annular cloth bag are both located in the air feeding cabin; the upper part of the first annular cloth bag and the upper part of the second annular cloth bag are both at least partially located in the air discharging cabin; a first annular channel and a second annular channel are respectively arranged in the air discharging cabin; the first annular channel is connected with the upper part of the first annular cloth bag through a first branch pipe; the second annular channel is connected with the upper part of the second annular cloth bag through a second branch pipe. The device provided by the inventionis used for solving the problems, such as large volume of dust collector caused by the arrangement of many cloth bags which occupy large space in the traditional bag type dust collector.

Description

technical field [0001] The invention relates to an environmental protection device, in particular to a device for filtering dust. Background technique [0002] The dust bag is called the heart of the bag filter, and it is generally called a dust bag or a filter bag. The dust bag is a key part in the operation of the bag filter. Usually, the cylindrical filter bag is hung vertically in the filter. The dust-removing bag in the traditional bag-type dust collector occupies a large area, so that when more bags are installed, the volume of the dust collector will increase. In addition, the work of bag-type dust removal includes the suction dust removal stage and the blast dust removal stage. The two working stages are generally carried out separately, so that the dust collector will stop working during the dust cleaning stage, which reduces the dust removal efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a device for filtering d...

Problems solved by technology

The dust-removing bag in the traditional bag-type dust collector occupies a large area, so that the volume of the dust collector will increase when more bags are installed. In addition, the work of bag-type dust removal includes the suction dust removal stage and the blowing dust cleaning stage. The two working stages are generally carried out separately, so that the dust collector will stop working during the dust cleaning stage, which reduces the dust removal efficiency.
