Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of electric dust-removing equipment, more specifically, it relates to a kind of wet electrical dust precipitator.
Background technology
In large-scale commercial production work, some workplace (such as thermal power plant etc.) can produce a lot of dust, these dust need just can be discharged in the external world after purifying and dedusting treater processes before discharge, otherwise can cause the pollution of environment, certainly every country is the most different about the standard discharging gas, but being as going from bad to worse of environmental problem, the emission request for flue dust is more and more higher, the meanwhile requirement for cleaner is also correspondingly improved.
Existing cleaner mainly has: cloth-sack-type dust removal, electric precipitation etc., wherein bag-type dust due to use condition reason (such as: high temperature resistant, corrosion-resistant etc.) higher for cloth bag material requirements, the most also need to be equipped with corresponding powerful blower fan, the non-recycled that belongs to of cloth bag itself recycles material simultaneously, causing the secondary pollution to environment, cost is also the highest simultaneously；The general multistage filter dirt piecewise connection of existing electric dust-removing equipment, the flue dust typically solid particle collected in flue dust after multistage filter dirt subregion, gradually reduce the dust content in flue dust, filter dirt subregion arranges collecting electrode plate；Filter dirt subregion arranges collecting electrode plate, after accumulating certain dust in collecting electrode plate, needs to clear up the dust of attachment in collecting electrode plate, if cleaning not exclusively can produce inverse corona, and thus causes electrical breakdown, reentrainment of dust, reduce dust removing effects.
Carry out the dust in collecting electrode plate is purged by two ways at present for problem above: dry dust removal and wet dust removal；Dry dust removal is typically passed through manually to beat collecting electrode plate or install rotor to drive brush to move to carrying out collecting electrode plate removing, and the structure of motor dust out is complicated simultaneously, overhauls inconvenience, and dust removing effects is less desirable；Wet dust removal is typically by circulating water flushing top-down to collecting electrode plate, but flushing process yet suffers from dust to lump in collecting electrode plate, flowing water flowing water in collecting electrode plate is uneven simultaneously, can not well dedusting, conventional flow-type bath causes the waste of water resource, and the cost that waste water processes simultaneously is the highest.
Summary of the invention
For prior art exist dedusting not thoroughly, efficiency of dust collection is low and in dust removal process, water consumption is too much problem, the present invention provide a kind of can high-effective dust-removing, low-cost production, the wet electrical dust precipitator more economized on water.
For achieving the above object, the present invention provides following technical scheme:
