Description
Technical field
The invention belongs to industrial dedusting purification techniques field, more particularly, relate to a kind of single blower fan dust absorbing clarifier and absorption cleaning method thereof.
Background technology
All a large amount of dust can be produced at mining industry, the broken industry of building stones, powder process industry, power industry, smelting industry, chemical industry, machine industry, severe contamination air, reduce the quality of life, destroy ecological environment, workman works in such circumstances simultaneously, probably cause that respiratory tract is narrow, lung capacity reduces or expiratory dyspnea, go down for a long time and can cause pneumoconiosis, harm recent and at a specified future date is caused to people, so must be controlled dust, do not allow its contaminated environment, be detrimental to health.
Existing dust clarifier is all generally the mode adopting gas circuit roundabout, thus reach the object of purification, but this method can cause the resistance of gas larger, also the power increase of air-introduced machine can be caused, thus energy consumption also strengthens, in addition, additionally use in existing technology and filter with filter mantle and the method crossing bag dust filter, the defect of this method is palpus periodic cleaning filter mantle and dust shield, use very inconvenient, service life is shorter, need often to change, safeguard inconvenience, and the filter area of filter bag is limited, if need to reach certain filter area, dust reclaiming clean device equipment volume will increase, production cost costly, the most important thing is the problem that thoroughly cannot solve purification micronic dust.
The absorption cleaning of inventor once with regard to welding cigarette did application, application number 201310371403.2, the applying date is on August 23rd, 2013, denomination of invention is: a kind of single blower fan weldering cigarette absorption cleaning device, this application case comprises smoke absorbing mechanism, weldering cigarette purification mechanism and weldering cigarette follower, described smoke absorbing mechanism comprises blower fan, weld fumes absorbs and is delivered to weldering cigarette purification mechanism by this blower fan, described weldering cigarette purification mechanism comprises clean room and backflush device, this backflush device is positioned at inside, clean room, and the bottom of this backflush device is connected with clean room, scavenging solution is equipped with in inside in clean room, weld fumes is delivered in the scavenging solution of backflush device inside by above-mentioned blower fan, described weldering cigarette follower acts on smoke absorbing mechanism, absorption weld fumes is followed the tracks of with speed of welding for controlling smoke absorbing mechanism.This application case utilizes backflush device to solve and how to make weldering cigarette enter easily and rest in the scavenging solution in clean room, then make tobacco by absorption cleaning by the effect of backflush device to scavenging solution, thus improve the efficiency of weldering cigarette absorption cleaning, if but weldering cigarette absorption cleaning device is used for the absorption cleaning to dust, its weak point is just apparent, the particle of weldering cigarette is less, what weldering cigarette absorption cleaning device solved is how to make it enter in scavenging solution, for this bulky grain of dust, the problem solved is not only how to enter in scavenging solution, its technological difficulties how to ensure that it is being atomized the clean-up effect in scavenging solution, and because dust granules is more heavier, need the blower fan guarantee assimilation effect of relatively high power, but the blower fan of relatively high power makes dust contact atomization scavenging solution after not only but also speeds away, cause too shortly can not ensure assimilation effect time of contact, especially the dusty gas contact area that concentration is larger is the low absorption efficiency of a step-down not more, and the filter of escape pipe upper end, steel wire lump and sponge block etc. all need often to change, increase purification cost virtually.
