Description
Technical field
The present invention relates to the dust arrester technical field, relate to a kind of fume dust remover in particular.
Background technology
Instantly, environmental protection has been global social concern, especially air pollution, and damaging range is big, the time is long, the extent of injury is dark.
Air pollution mainly is that the waste gas that factory emits causes, and factory in process of production; A lot of boilers can give off flue gas, if these flue gases do not pass through harmless treatment, and the harmful substance that wherein contains; Be directly to be emitted on airbornely, therefore, dust arrester just occurred; Utilize dust arrester the flue dust in the flue gas to be removed allow compliance with emission standards, existing dust arrester; What much adopt is the spray mode, and the liquid curtain and the flue gas that spray through spray equipment exchange, to reach the purpose of dedusting; Patent publication No. is CN 201431840, open day to disclose a kind of fume dust remover for the Chinese utility model patent of 2010-03-31; It is included in lower part of frame and contains into mouth, gas flue, impeller dust arrester, dedusting spray equipment, liquid bath and the liquid back pipe that is connected with liquid bath and feed flow pond, and dividing plate is housed in housing, contains screen pack on the top of dividing plate; The cleaning spraying device that is connected with the feed flow pond is housed above screen pack, above cleaning spraying device, is shaped on exhaust opening; The spout of Flue Gas Pretreatment Device also is housed in advancing mouth in addition.But, the dust arrester of this utility model, the effect of its dedusting, removal harmful substance is poor, the structure more complicated.
Summary of the invention
The objective of the invention is the weak point to prior art, a kind of fume dust remover is provided, its dedusting, remove the effective of harmful substance.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is following: a kind of fume dust remover; Comprise liquid storage pool, have gas approach the smog collecting chamber, be provided with exhausting window dirt pocket, be installed in the delivery pump that spray equipment and said spray equipment in the said dirt pocket are communicated with; Said dirt pocket is provided with and exceeds attending the switch room, being positioned at the following collecting chamber of said exhausting window below of said smog collecting chamber top; It is indoor that said spray equipment is installed in said upward exchange; Said smog collecting chamber is communicated with through air exhauster and the said dirt pocket that is arranged near said smog collecting chamber top, the said liquid sealant that is provided with screen pack in the collecting chamber down, is positioned at said screen pack top.
Fume dust remover of the present invention has independently smog collecting chamber and dirt pocket, and both are communicated with through air exhauster, and air exhauster can be installed in smog collecting chamber or the dirt pocket; It, goes so this position makes air exhauster more easily flue gas extracted out because flue gas is low weight near smog collecting chamber top, gets into dirt pocket; Raise the efficiency, simultaneously, dirt pocket is provided with the switch room of attending that exceeds said smog collecting chamber top, and last switch room exceeds smog collecting chamber top; So, the flue gas from air exhauster comes out naturally upwards wafts, and the liquid curtain with the spray equipment ejection when wafing contacts fully; Remove flue dust and harmful substance, flue gas is discharged from exhausting window then, accomplishes whole dedusting exchange process, and the sediment of removed dust and harmful substance is filtered net and stops; Screen pack is because the reason of liquid tension can form the liquid sealant above that, and the aperture of thickness and screen pack is relevant, and the aperture more carefully; The liquid sealant can be thicker, otherwise thin, the liquid sealant can stop that flue gas overflows from screen pack; Get into liquid storage pool, the dust of while aids precipitation on screen pack etc. can play better filtration.
As preferably, said gas approach comprises and is arranged on the vertical import on the said smog collecting chamber diapire and is arranged on the inclination import on the said smog collecting chamber sidewall.
Gas approach is two; And one be vertical; Another one tilts, and two gas approach can make the flue gas that gets into the smog collecting chamber mix fully, after the flue gas after mixing is convenient to get into out the dirt chamber; After the liquid curtain of spray equipment ejection contacts, can play better dust removing effects.
As preferably, said vertical import becomes 35-45 ° of angle with said inclination import.
The vertical angle that become with said inclination import of import, too greatly, too little all bad, in 35-45 ° of scope, the flue gas of two imports mixes the most even.
As preferably, said spray equipment is installed in the said top, switch room of attending.
Spray equipment is arranged on attendes the top, switch room, spray from the top down, and flue gas is to waft from bottom to top, good dedusting effect like this.
As preferably, said dirt pocket is provided with the screen pack replacement port, on the said screen pack replacement port seal cover is installed.
The screen pack replacement port is used for changing screen pack, guarantees the operating efficiency of whole dust arrester.
As preferably, said screen pack replacement port lowest part exceeds said liquid sealant upper surface, and said screen pack replacement port highest point is positioned at said exhausting window below.
Screen pack replacement port lowest part exceeds said liquid sealant upper surface, like this, just need not consider the fluid tightness of seal cover; Only need the flue gas sealing just passable; Reduced cost and manufacture difficulty, guaranteed the integrality of liquid sealant, and then guaranteed dust removing effects.
As preferably, said exhausting window comprises and is arranged on a plurality of inclined via-holes that from inside to outside reduce highly gradually on the said dirt pocket sidewall that said inclined via-hole becomes 30-45 ° of angle with horizontal plane.The setting of inclined via-hole can either make flue gas to get rid of, and has prolonged the time of flue gas in dirt pocket again, has strengthened dust removing effects.
As preferably, said liquid storage pool is provided with the dividing plate that said liquid storage pool is divided into sedimentation basin and clean solution tank, and the import of said delivery pump and clean solution tank are communicated with, and said dirt pocket is communicated with said sedimentation basin.
Used liquid gets into clean solution tank again through the sedimentation basin post precipitation, and impurity is few, has guaranteed the operate as normal of delivery pump, has reduced the spray equipment phenomenon of blocking, has guaranteed the effect of dedusting.
As preferably, said exhausting window highest point is lower than said air exhauster bottom.
Like this, can directly not discharge, guarantee the effect of dedusting from exhausting window from most flue gases that air exhauster comes out.
As preferably, be provided with rack in the said following collecting chamber, said screen pack places on the said rack.
Screen pack directly is placed on the rack, and it is convenient to change, and has guaranteed the efficiency of dust collection and the effect of whole dust arrester.
Beneficial effect of the present invention is:
Dust arrester of the present invention, its good dedusting effect, efficient height.
