Problems solved by technology

Traditional soot blowers are mostly steam soot blowing and shock wave soot blowing. Steam soot blowing blows soot on the heating surface of the boiler through a movable nozzle that can be inserted into the boiler. In order to expand the range of blowing, the steam pressure of soot blowing is relatively low High, the heating surface close to the nozzle is prone to wear; the shock wave generated by the deflagration of combustible gas is sent into the boiler through the fixed nozzle by shock wave soot blowing, and the blowing pressure is also high, so the heating surface close to the nozzle is also prone to wear

Abstract

The present application provides a purging device, which includes: a nozzle, used to spray a purge medium to purge the surface to be purged; a deformable channel, connected to the nozzle; a fixed channel, connected to the deformable channel; a transmission member passing through the deformable channel and the fixed channel, and used to control the movement of the fixed channel and the deformable channel so that the spray head reaches the target position of the surface to be cleaned performing purging; the driving device is connected with the transmission part and is used to control the transmission part. According to the application, by controlling the transmission parts to drive the movement of the fixed channel and the deformable channel, the nozzle can be moved to any position on the surface to be purged, and the purging range is expanded, and only low-pressure medium is used for soot blowing, which reduces the wear of the heating surface , Improve the heat exchange efficiency of the boiler and reduce the operating cost.

Description

technical field [0001] The present application relates to the technical field of environmental protection, and more specifically relates to waste incineration. Background technique [0002] The boiler recovers flue gas heat through heat exchange on the heating surface. The fly ash produced by fuel combustion will stick or accumulate on the heating surface of the boiler, hindering the heat exchange between the flue gas and the heating surface, thereby reducing the efficiency of the boiler. Traditional soot blowers are mostly steam soot blowing and shock wave soot blowing. Steam soot blowing blows soot on the heating surface of the boiler through a movable nozzle that can be inserted into the boiler. In order to expand the range of blowing, the steam pressure of soot blowing is relatively low High, the heating surface close to the nozzle is prone to wear; shock wave soot blowing uses the shock wave generated by the deflagration of combustible gas to be sent into the boiler thr...
