Technical field
The utility model relates to dust arrester technical field, relates in particular to a kind of single chamber three electric fields-bag-type combined dust collector.
Background technology
Bag-type dusting and electric cleaner are that application is at present comparatively extensive, the reasonable dry dust removal mode of effect, it is high that electric cleaner has purification efficiency, drag losses is little, smoke treatment amount large, automaticity high, it is high that bag-type dusting has efficiency of dust collection, can not cause secondary pollution, be convenient to reclaim the features such as siccative.Three electric field electric cleaners are a kind of high-efficiency electric dust catchers, but because three electric field electric cleaners processing effective time of staying of flue dust are short, can not effectively process the dust in flue gas of sintering machine head, so there is the problem that dust exhausting concentration after dedusting still can not be up to standard and flue gas collection rate is low, electric precipitation there are certain requirements dust specific resistance simultaneously, so dust is had certain selective, can not make the very high purification efficiency of all dust acquisition all; And when bag-type dust collector is directly used in to primary dust removing, because dust concentration is large, there is stopping up even breakage and cause often changing filter bag, the situation that business burden increases the weight of in filter bag.In addition, in duster system, vibration dust-cleaning is an important mechanism, and the design of vibration body, operation quality will be directly connected to the efficiency of dust collection of electric cleaner.
Summary of the invention
The utility model provides a kind of single chamber three electric fields-bag-type combined dust collector, and with three electric field dedustings, as primary dust removing, bag-type dust, as two-stage dust removal, adds acoustic wave soot blower simultaneously, and efficiency of dust collection is high, and energy-conserving and environment-protective are applicable to various flue gas ash removals.
In order to achieve the above object, the utility model is realized by the following technical solutions:
A kind of single chamber three electric fields-bag-type combined dust collector, comprise three electric field dust arresters, bag-type dust collector, the ash exhauster that is located at dust arrester bottom, air inlet, gas outlet and be located at the acoustic wave soot blower on deduster top, described three electric field dust arresters are located at air inlet one end, and end connects bag-type dust collector and gas outlet.
Described air inlet is provided with multilayer airflow-distribution board.
Described connector is provided with trough plate device.
The dust collecting pole plate of described three electric field dust arresters adopts tubulose utmost point row, and material is ratio-frequency welded tube.
The discharge electrode of described three electric field dust arresters adopts stainless steel fish-bone spray point, and the 3rd electric field increases tubulose auxiliary electrode.
Described bag-type dust collector is comprised of deep bead, dividing plate, filter bag, bag cage, clean room.
The ash exhauster of described dust arrester is comprised of unloading valve, vibrating motor and ash bucket, and damping device is set.
Compared with prior art, the beneficial effects of the utility model are:
1) adopt three electric field dedustings as primary dust removing, efficiency of dust collection is high, and drag losses is little, allows operating temperature high, processes gas scope amount large.
2) adopt bag-type dust as two-stage dust removal, utilize its high purification efficiency to guarantee gas qualified discharge, when temporary fault appears in electric cleaner, also dust removing effects can be guaranteed, because the dust concentration of filtering reduces, service life and the replacement cycle of filter bag can be extended simultaneously.
3) adopt acoustic wave soot blower, ash-removal effect is good, and power consumption is little, harmless to equipment.
