The vertical angle that becomes with described 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, described spray equipment is installed in top, described upper switch room.
Spray equipment is arranged on top, upper switch room, spray from the top down, and flue gas is to waft from bottom to top, like this good dedusting effect.
As preferably, described dirt pocket is provided with the filter screen replacement mouth, on the described filter screen replacement mouth seal cover is installed.
The filter screen replacement mouth is used for changing screen pack, guarantees the operating efficiency of whole dust arrester.
As preferably, described filter screen replacement mouth lowest part exceeds described hydraulic seal layer upper surface, and described filter screen replacement mouth highest point is positioned at described exhausting window below.
Filter screen replacement mouth lowest part exceeds described hydraulic seal layer upper surface, like this, does not just need to consider the fluid tightness of seal cover, only need the flue gas sealing just passable, reduced cost and manufacture difficulty, guaranteed the integrality of hydraulic seal layer, and then guaranteed dust removing effects.
As preferably, described exhausting window comprises and is arranged on a plurality of inclined via-holes that from inside to outside reduce highly gradually on the described dirt pocket sidewall that described inclined via-hole becomes 30-45 ° of angle with horizontal plane.The setting of inclined via-hole can either prolong again the time of flue gas in dirt pocket so that flue gas can be got rid of, and has strengthened dust removing effects.
As preferably, described liquid storage pool is provided with the dividing plate that described liquid storage pool is divided into sedimentation basin and clean solution tank, and the import of described delivery pump and clean solution tank are communicated with, and described dirt pocket is communicated with described sedimentation basin.
Used liquid enters clean solution tank after precipitating through sedimentation basin again, and impurity is few, has guaranteed the normal operation of delivery pump, has reduced the phenomenon that spray equipment stops up, and has guaranteed the effect of dedusting.
As preferably, described exhausting window highest point is lower than described air exhauster bottom.
Like this, can directly not discharge from exhausting window from air exhauster most flue gases out, guarantee the effect of dedusting.
As preferably, be provided with rack in the described lower collecting chamber, described screen pack places on the described rack.
Screen pack directly is placed on the rack, and it is convenient to change, and has guaranteed efficiency of dust collection and the effect of whole dust arrester.
The utility model beneficial effect is:
