Abstract

The invention discloses a reverse blowing component which comprises a pulse valve and a spraying and blowing structure connected with the pulse valve. A venturi tube is oppositely arranged an outlet of the spraying and blowing structure, the spraying and blowing structure comprises a spraying and blowing pipe and a nozzle connected with the spraying and blowing pipe, the spraying and blowing pipe is a heat compensation pipe body, heat compensation of the pipe body can be achieved under the high-temperature reverse blowing condition through the heat compensation pipe body, the spraying and blowing pipe can effectively keep alignment accuracy when the spraying and blowing structure is used, so that the nozzle is easily disassembled and assembled, and the reverse blowing effect of a gas filtering device is better.

Description

technical field [0001] The invention relates to the technical field of gas filtration, in particular to a blowback assembly. Background technique [0002] At present, gas filter devices are widely used in the fields of metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, and urban water supply. The rigid filter element used in the gas filter device under high temperature and high pressure will trap dust and impurities when filtering. The dust and impurities will accumulate and adhere to the surface of the filter element, which will reduce the filtration efficiency of the gas filter device, so the general gas filter device will be designed with back blowing Components to remove dust and impurities on the filter element. [0003] Such as figure 1 As shown, the blowback assembly in the prior art includes a pulse valve 2a, a blowing pipe 11a, and a nozzle 12a, and a Venturi tube 3a is provided directly opposite the nozzle 12a, wherein ...
