Problems solved by technology

[0002] The high-temperature pulse cleaning bag dust collector in the cement industry is a newly developed dust collection equipment in China. The pulse valve is one of the main components of the dust collector. Since the pulse valve is directly connected to the process hot gas, the single side of the pulse valve diaphragm has Exposure to high temperature gas, easy aging, short service life and high cost

Embodiment Construction

[0012] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0013] see figure 1 and figure 2 , a self-cooling air blowing device, is to insert one end of the connecting pipe 8 outside the box from the connecting pipe end of the gas storage tank 3, and connect with the pulse valve 1 containing the diaphragm 2 connected to the flange end of the gas storage tank 3, After adding the "O" type sealing ring 11 at the port position of the connecting pipe end of the gas storage tank 3, lock it with the connecting pipe 8 outside the box with the pipe sealing nut 10. Then insert the other end of the connecting pipe 8 outside the box into the wall-through connection pipe 7 installed on the box body 4, lock the box outer nut 12 on the wall-through connection pipe 7, between the pipe sealing nut 10 and the box ou...

Abstract

The invention relates to a kind of self-help chilling airflow puffing apparatus, which involves in dust-precipitator of soot cleaning sack with high temperature and impulse. To solve the problem of that one-side of impulse valve's diaphragm contacts high temperature gas for long haul, the technical scheme features of the invention can be embodied as follows: in the wall of box outside communicating pipe, there is an air inlet port. And the apparatus has a non-return valve on the air inlet port, which is an opening interstice of screw-adjusting valve in orb form, and the opening of valve orients to the lean underside. After adding O type joint ring in adapter port of air storage tank that have be inserted the communicating pipe at the box outside, lock sealed nut of the pipe to the communicating pipe in box outside tightly. It can decline temperature in the condition of impulse valve's diaphragm in order to prevent from high temperature's aging of the impulse valve's diaphragm, so that it can prolong its life span that is the specific mark of the invention.

Description

technical field [0001] The invention belongs to the technical field of environmental protection dust collection in the cement industry, in particular to a self-cooling airflow injection device used on a high-temperature pulse dust-cleaning bag dust collector. Background technique [0002] The high-temperature pulse cleaning bag dust collector in the cement industry is a newly developed dust collection equipment in China. The pulse valve is one of the main components of the dust collector. Exposure to high-temperature gas is prone to aging, short service life and high cost. Contents of the invention [0003] In order to solve the current problems caused by the long-term contact of one side of the diaphragm of the pulse valve with high-temperature gas, the present invention provides a self-cooling airflow blowing device with simple structure, good cooling effect, and absolute protection of the diaphragm from high-temperature erosion. [0004] The technical solution adopted ...
