The driving shaft (211) is externally connected with a motor to realize power input, the coarse filtration box (1) carries out coarse filtration on flue gas containing a large amount of dust particles through preliminary spraying, then the flue gas enters the air inlet (24), and the flue gas is subjected to first-step filtration and is distributed to the A chamber and the B chamber through the first filter leaf (34) and the second filter leaf (35), so that the dust particles in the flue gas are filtered step by step, the filtering effect is improved, and the efficiency is improved.
5. A method of using a spray filter for soot treatment according to claim 4, wherein: due to the speed and torque reducing effects of the first gear (54), the second gear (55) and the third gear (56), the cam (58) has a certain torque and a slow rotation speed, and the switching process of the filtering state and the cleaning state is facilitated, so that the cam (58) rotates for one circle in the whole working process, the majority of time is in the filtering state, the minority of time is in the cleaning state, namely, the filtering and dedusting are automatically started to be cleaned for a period of time, the waste time of manual cleaning and shutdown cleaning is saved, the working content is increased, and the maintenance cost and the time cost are reduced.
6. A method of using a spray filter for soot treatment according to claim 5, wherein: the connecting rod (65) synchronous pivoted deflection rod (81) for deflection rod (81) rotates and jack up third region (86) of lifter plate (83), makes lifter plate (83) rise, and then makes base plate (71) rise, changes the spraying effect at body of a tower (23) top, accomplishes the cleanness to body of a tower (23) inner wall, makes the self-cleaning process of whole device from top to bottom closed loop, has strengthened self-cleaning effect.
