Problems solved by technology

Since the raw gas enters the filter element continuously from the raw gas chamber, the purified gas filtered through the filter element enters the purified gas chamber without interruption. Blowing gas causes resistance, which increases the difficulty of blowback. The dus

Abstract

The invention discloses a gas filtering device. The gas filtering device comprises a filtering device shell and a pore plate, wherein the pore plate is arranged inside the filtering device shell and partitions the filtering device shell into a lower raw gas cavity and an upper pure gas cavity; at least two filter element groups are arranged below the pore plate; a back-blowing device connected with a back-blowing gas source is arranged above each filter element group; the pure gas cavity is partitioned into at least two independent chambers which are isolated from each other; at least one back-blowing device is arranged in each independent chamber; each independent chamber is provided with a valve opening used for discharging pure gas; a control mechanism used for controlling each valve opening to be opened and closed is arranged on the valve opening. The back-blowing resistance is overcome through the structure, and meanwhile, the gas filtering device keeps working continuously.

Description

technical field [0001] The invention relates to a gas filter device, in particular to a gas filter device capable of off-line backflushing. Background technique [0002] When the gas filter is filtering, the dust particles will gradually form a layer of filter cake on the surface of the filter element. In order to remove the dust on the surface of the filter element, the gas back blowing method is usually used to blow the surface of the filter element with the help of external high-pressure gas. At present, the structure of the gas filter device includes a gas filter device housing and a filter element group arranged in the gas filter device housing, and the gas filter device housing is divided into an upper clean gas chamber and a lower raw gas chamber ("raw gas chamber") by an orifice plate. "refers to the gas before filtration, and "clean gas" refers to the gas after filtration), the lower part of the original gas chamber is provided with a settling chamber for dust to se...
