Description
Technical field
The utility model relates to a kind of sound wave ash remover, specifically a kind of sound wave ash remover frequently of changing voice again.
Background technology
Be used in the industry coal-boiler all can producing problems such as dust stratification, slagging scorification, fouling in heat exchange in the tube bank of heat exchange, on tube wall, form dust stratification, slagging scorification, scale formation, the thermal conductivity factor of tube bank is significantly reduced, serious dust stratification, fouling also entail dangers to the safe operation of boiler.For eliminating dust stratification, slagging scorification, the fouling in the tube bank, adopt HCS soot blower, static soot blower, rotary steam sootblowers, cloth bag soot blower, steel ball rapping soot blower, sound wave ash remover etc. that ash disposal is carried out in tube bank at present usually.The structure of existing a kind of sound wave ash remover is: in the audio feedback body water conservancy diversion cover is housed, be provided with eddy current generation body assembly near the exit in the water conservancy diversion cover, the front end of eddy current generation body assembly is connected with pole, the other end of pole is connected with an audio-frequency generator, stretched into a wireway in the water conservancy diversion cover, the outlet of wireway is relative with the rear end of eddy current generation body assembly.The deficiency that this sound wave ash remover exists is: the eddy current generation body of eddy current generation body assembly front portion is a cone, air communication cross after it the eddy current that forms strong inadequately; Audio-frequency generator can not form the audio frequency of compound variation.
The utility model content
The purpose of this utility model is to provide a kind of sound wave ash remover frequently of changing voice again, and it can make air-flow form stronger eddy current, and can form the high-strength audio frequency of compound variation, and then reaches better dust removing effects.
For achieving the above object, the utility model adopts following scheme: the sound wave ash remover frequently of changing voice again, in the one audio feedback body water conservancy diversion cover is housed, be provided with eddy current generation body assembly near the exit in the water conservancy diversion cover, the front end of eddy current generation body assembly is connected with pole, the other end of pole is connected with an audio-frequency generator, in the water conservancy diversion cover, stretched into a wireway, the eddy current generation body that eddy current generation body assembly is had is hemispherical, in the water conservancy diversion cover, the uncovered sleeve pipe of a front end is housed, the front end of sleeve pipe docks with eddy current generation body assembly rear end, and wireway joins with sleeve pipe and communicates with its inner chamber, is provided with spiral helicine groove on the inwall of audio-frequency generator.
By such scheme as seen, the air-flow that is blown out by wireway is through behind the hemispheric eddy current generation body, air-flow can form stronger eddy current, because the inwall of audio-frequency generator is provided with spiral helicine groove, after the inwall reflection of air-flow through audio-frequency generator, can form the audio frequency of compound variation, the audio frequency of this compound variation passes through the reflection of audio feedback body again, can form the high audio of compound variation, the high audio of this compound variation can reach better dust removing effects.
The utility model is rational in infrastructure, and the high-strength audio frequency of compound variation that it produced can reach better dust removing effects.
