Problems solved by technology

[0003] The existing rotary air preheater adopts a relatively traditional installation and sealing structure, and the inner wall of the rotary air preheater generates more smoke and dust during the working process. In order to avoid the reduction of its sealing performance, it is necessary to install a cleaning device inside mechanism, to avoid the decrease of heat exchange efficiency due to excessive smoke and dust, and generally high-pressure cleaning is used, but this cleaning method cannot effectively clean the inner wall, so further improvements are needed on this basis

Abstract

The invention relates to the technical field of cleaning devices, in particular to a rotary air pre-heater cleaning device which comprises a sealed hearth, a supporting frame is fixedly installed outside the end, close to the ground, of the sealed hearth, and a cleaning assembly is installed in the sealed hearth; the adjusting assembly is rotationally connected to the interior of the supporting frame and is in transmission connection with the cleaning assembly; the reversing set is rotationally connected to the interior of the adjusting assembly; the driving set is fixedly installed in the supporting frame and is in transmission connection with the adjusting assembly; compared with the prior art, the inner wall of the air preheater can be cleaned, smoke on the inner wall of the sealed hearth can be removed, the situation that the heat exchange efficiency is reduced due to excessive smoke in the sealed hearth is avoided, and the situation that the sealing performance is reduced due to the fact that cleaning is conducted due to disassembly, assembly and maintenance is avoided; and the cleaning range of the cleaning assembly can be widened through the adjusting assembly.

Description

technical field [0001] The invention relates to the technical field of cleaning devices, in particular to a rotary air preheater cleaning device. Background technique [0002] Rotary air preheater is the abbreviation of rotary air preheater. It is a heat exchange equipment for large boilers. It uses the heat of boiler flue gas to heat the air required for combustion, thereby improving the efficiency of the boiler. [0003] Since the existing rotary air preheater adopts a more traditional installation and sealing structure, more smoke and dust are generated on the inner wall during the working process of the rotary air preheater. To avoid the reduction of heat exchange efficiency due to excessive smoke and dust, high-pressure cleaning is generally used, but this cleaning method cannot effectively clean the inner wall, so further improvements are needed on this basis. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to provide a rotary air preheater...
