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, also comprise the flue gas guide shell, described flue gas guide shell comprises lower stationary magazine creel, is positioned at the upper guide shell in the described pipe outside and stops gusset, described upper guide shell is made of a plurality of deflectors, described deflector lower end is hinged on the described lower stationary magazine creel by jointed shaft, and cover has torsion spring on the described jointed shaft, and described torsion spring one end acts on the described deflector outer surface, the other end acts on the described lower stationary magazine creel inner surface, and the described gusset that stops contacts with described deflector inner surface.
Upper guide shell is arranged on the pipe outside, pipe is surrounded, like this, the flue gas of discharging from pipe can act on the upper guide shell, and upper guide shell is to be made of a plurality of deflectors, that is to say that flue gas can act on the deflector, overcome the power of torsion spring, can produce an outside swing, flowing of flue gas is actually a dynamic flow process, and its power that acts on the deflector also changes, this is with regard to so that deflector can carry out a small swing always, this swings meeting so that flue gas upwards faster, also so that flue gas mixing more even improved dust removing effects.
As preferably, described flue gas guide shell is inverted truncated cone-shaped, and the width of the upper shed that forms less than described upper guide shell upper end and described pipe of the under shed width that forms of described lower stationary magazine creel lower end and described straight smoke pipe.
Under shed wants narrower with respect to upper shed, has guaranteed that flue gas overflows from upper shed, improves dust removing effects.
As preferably, described surge drum 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.
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 improved 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.
The utility model beneficial effect is:
Dust arrester of the present utility model, its good dedusting effect, efficient height.
