Description
Technical field
The invention belongs to the dedusting technology field, be specifically related to a kind of dust collection method and equipment that is used for the boiler of usefulness such as hospital.
Background technology
The desulfurating dust-removing equipment that uses now can't realize reaching the requirement of (DB65/2154-2004, DB65/2154-2010) standard.Thereby the work of gathering dust is to be accomplished by other equipment (sack cleaner).
Many knowledges, desulfurizing tower all adopts the spraying technique equipment in the technology, in the desulfurizer that has now, the shower nozzle that various shower type or impact type are arranged that installs additional, the material that is this shower nozzle ejection can not be called " mist ", claims that " globule " is comparatively suitable.The process of in existing desulfurizer, working, also there is 5% water smoke in the eddy current surface; The chemical reaction specific area of desulfurizing agent is not enough, has limited the equipment work efficiency, causes desulphurization reaction fully not carry out, and this is the main cause that influences desulfation dust-extraction device production efficiency.
Cleaner is that the harmful substances such as sulphur that exist in the flue gas are gone out through water, carbon etc.The cleaner of large-sized boiler is that the flue gas that contains harmful substance is sent into gas wash tower (king-tower) then through carrying out dedusting through sucking tower.This structure dust removing effects is relatively poor, and efficient is low, is difficult to satisfy the demand of using.
Summary of the invention
The purpose of this invention is to provide a kind of novel dust collection method and equipment, overcome the above-mentioned deficiency of prior art, have that structural design is simple, a good dedusting effect, advantage that efficient is high.
