Include the entrance guiding plate being arranged between air inlet and filter bag and the uniform baffle being arranged on below filter bag in the ash bucket of bottom；
The entrance guiding plate is 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
Angle with vertical direction is 0～45 °, and is inclined away from air inlet one end downwards.
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 elongated setting of bottom ash bucket respective side.
By multiple reinforcement link of boards between the uniform deflector and the headwall of bottom ash bucket.
The uniform deflector is straight panel or bent plate.
The uniform deflector is for multiple, and the arrangement that is along inclined direction stepped, and between each uniform deflector, uniformly leads
It is connected by rebound between stream plate and bottom ash bucket headwall, forms the stereoeffect with enclosed, outer surface.
Compared with prior art, the invention has the beneficial effects as follows：
1) fabricated structure is adopted, first passes through entrance guiding plate and the airflow diversion of top warehouse will be entered, then by uniform
Baffle makes the air-flow of entrance ash bucket uniform along longitudinal direction；
2) reaction efficiency of dust removing effects and desulphurization denitration can be greatly increased；
3) simple structure, easy to implement, can be used for grassroot project and rebuilding old equipment.
