Dust collector

Abstract

The invention discloses a dust collector. The dust collector comprises a case, an air inlet pipe, a filter element, a backflush pipe and an air outlet pipe, wherein the air inlet pipe, the filter element, the backflush pipe and the air outlet pipe are arranged on the case; the case is composed of an upper case and a lower case which are connected, a fixing plate is arranged between the upper caseand the lower case, and the lower case is composed of a cylindrical unit and a conical unit which are connected; the air inlet is arranged on the cylindrical unit; the fixing plate is provided with the filter element, and both ends of the filter element are arranged inside the upper case and the lower case respectively; the backflush pipe is arranged at the top of the upper case; the filter element and the backflush pipe are coaxially arranged; the air outlet pipe is arranged on the side wall of the upper case. The dust collector is characterized in that the flowing direction of backflush airis identical to the falling direction of dusty air flow, so that dust can be easily removed from a filter tube to achieve self-cleaning effects, then the service life of the filter tube can be prolonged, and meanwhile, direct exchange between input air flow and backflush air flow can be avoided and dust cleaning effects can be ensured.

Description

technical field [0001] The invention relates to a collecting device, in particular to a dust collector. Background technique [0002] Dust collectors are widely used in petrochemical, biochemical, food and beverage, pharmaceutical and chemical industries, nuclear industry exhaust emissions and other industries, mainly used for filtration of high-temperature continuous working gases and dust recovery. The petrochemical industry is mainly used in the following devices: continuous reforming catalyst dust recovery, propane dehydrogenation catalyst dust recovery, polyolefin gas filtration, polypropylene device process gas filtration, polyethylene device process gas filtration, melamine device process gas filtration, etc. . In the prior art, various industries mostly use bag-type dust collectors or cartridge-type dust collectors. However, after a period of use, whether it is a bag-type dust collector or a cartridge-type dust collector, the accumulation of dust will seriously affe...

Problems solved by technology

In the prior art, various industries mostly use bag-type dust collectors or cartridge-type dust collectors. However, after a period of use, whether it is a bag-type dust collector or a cartridge-type dust collector, the accumulation of dust seriously affects the filtering effect of the filter. , in order to ensure the air purification effect, it is necessary to spend a lot of manpower and material resources for the cleaning of the filter cartridge and filter element, which greatly increases the use cost of the dust removal device.
