The entrance guiding plate be arranged in parallel with filter bag, and the gas channel upper/lower terminal between entrance guiding plate and air inlet connects respectively
Logical top warehouse and bottom ash bucket；Uniform baffle is made up of one to multiple piece of uniform deflector, and uniform deflector is obliquely installed, its
It is 0~45 ° with the angle of vertical direction, and is inclined downwards away from air inlet one end.
The cross section of the top warehouse and bottom ash bucket is rectangle, and entrance guiding plate, uniform baffle are respectively along top
Warehouse or the bottom elongated setting of ash bucket respective side.
Strengthen link of boards by multiple between the uniform deflector and the headwall of bottom ash bucket.
The uniform deflector is straight panel or bent plate.
The uniform deflector is multiple, and the arrangement that is along inclined direction stepped, and between each uniform deflector, is uniformly led
Connected by rebound between stream plate and bottom ash bucket headwall, form the stereoeffect with enclosed, outer surface.
Compared with prior art, the beneficial effects of the utility model are：
1) fabricated structure is used, first passing through entrance guiding plate will enter the airflow diversion of top warehouse, then by uniform
Baffle makes the air-flow for entering ash bucket uniform along longitudinal direction；
2) reaction efficiency of dust removing effects and desulphurization denitration can be greatly increased；
3) simple structure, it is easy to implement, can be used for grassroot project and rebuilding old equipment.
