7. A wet desulphurization dust collector as claimed in claim 4, wherein the diversion pipe sleeve (27) is of a V-shaped structure, and the top of the diversion pipe sleeve (27) is provided with an air outlet (28) at both ends.
8. The use method of the wet desulphurization dust remover as claimed in claim 7, characterized by comprising the following concrete steps:
the method comprises the following steps: opening a manual valve (3) on an air inlet pipeline (2) and an exhaust pipeline (12), enabling smoke to enter a cyclone dust removal part at the bottom of a tower body (1) from the air inlet pipeline (2), enabling the smoke subjected to cyclone dust removal to flow to a porous distribution plate (13), enabling the smoke to pass through a plurality of circulation pipes (31) in the process of passing through the porous distribution plate (13), discharging the smoke from an air hole (30), so that the smoke flows to a protection assembly (14), and then discharging the smoke from two air outlets (28) on the protection assembly (14);
step two: the solution in the water tank (8) is pumped out by the pressure water pump (7) through the water pumping pipe (18), the solution is sent into the spray tray (22) through the connecting pipe (19) and the water sending pipe (20), the solution is uniformly sprayed out from the atomizing nozzle (24) at the bottom of the spray tray (22) to spray the flue gas discharged from the air outlet (28), the desulfurization treatment of the flue gas is realized, the desulfurized flue gas continuously rises and is discharged from the exhaust pipeline (12), the solution slides into the water storage tank (26) along the outer wall of the diversion pipe sleeve (27) to be stored in the spraying process, and when the water storage tank (26) is full, the water can be discharged by opening the water discharging valve;
step three: when the interior of the porous distribution plate (13) is blocked, the box door (16) is opened, the protection assembly (14) is taken out, all the pneumatic telescopic rods (25) are driven to stretch by the air cylinder (17), the dredging pipe (23) is pushed into the circulating pipe (31) to dredge the circulating pipe (31), and discharged dirt falls into the bottom of the tower body (1).
