A kind of electric dust collector
【Technical field】
The present invention relates to the technical field of electric dust collector, particularly a kind of technical field of electric dust collector.
【Background technology】
Electric cleaner is the indispensable corollary equipment in thermal power plant, and its function is by combustion stove or oil burning boiler row
The particle flue dust put in flue gas is removed, thus the fume amount that enter in atmosphere is greatly lowered, this is
Improve environmental pollution, improve the important environmental protection equipment of air quality.Its operation principle is that flue gas is removed by electricity
So as to flue dust is positively charged during flue before dirt device agent structure, then flue gas enters setting multilayer cathode plate
Electric cleaner passage.Due to the mutual suction-operated of positively charged flue dust and negative electrode electroplax, make in flue gas
Particle flue dust adsorbs on negative electrode, and minus plate is hit in timing, makes to have certain thickness flue dust and in deadweight and shakes
Fall in the ash bucket below electric cleaner structure under dynamic double action, thus reaching the cigarette removed in flue gas
The purpose of dirt.Existing electric dust-removing equipment is mostly vertical structure, and ash bucket is located at the bottom of electric cleaner, long
Phase uses rear easily accumulation a large amount of dust on ash bucket, because flue gas enters from the bottom of electric cleaner, easily
Flue dust in ash bucket is kicked up, causes secondary pollution, the dust removal efficiency of impact flue gas.
According to statistics, ash-transmission system blocks up ash and forces electric cleaner stoppage in transit, accounts for the total accident rate of electric cleaner
30%~40%.The phenomenon of stifled ash or paulin ash, in the actual motion of electric cleaner, usually occurs in ash bucket,
Lead to the defeated ash of electric cleaner not smooth, reduce the efficiency of dust collection of electric cleaner.When ash stifled in ash bucket or paulin ash simultaneously
During the pole plate of arrival electric cleaner, easily cause electric field short circuit, affect the safe operation of electrical equipment, simultaneously
Damage the internals of electric cleaner, cause deformation of electric cleaner pole plate, polar curve etc., produce unrepairable
Damage, and may lead to electric field trip.In some instances it may even be possible to cause ash bucket to come off during serious dust stratification in ash bucket
Or even the caving in of whole electric cleaner.
