9. The use method of the environment-friendly flue gas treatment device as recited in any one of claims 1 to 8, characterized in that the method comprises the following steps:
the method comprises the following steps: firstly, a main structure part of the device is formed by a purification tower body (1) and a dust removal box (3), untreated flue gas enters from a smoke inlet pipe (4) at one side of the dust removal box (3), the flue gas firstly enters the bottom in the dust removal box (3), then the flue gas moves from bottom to top, passes through a gas guide plate (7) and enters a dust removal cloth bag (9) at the inner side of a cloth bag fixing frame (8), and the flue gas is filtered through the dust removal cloth bag (9) to remove dust in the flue gas;
step two: the flue gas after dust removal of the dust removal box (3) enters the interior of the purification tower body (1) through the connecting bent pipe (2), passes through an active carbon layer (17) in the purification tower body (1) for adsorption and purification again, then rises, passes through the particle catcher (18), catches and filters particles in the flue gas through the particle catcher (18), completes the three-time purification treatment of the flue gas, and then is discharged through the smoke discharge pipe (14);
step three: after the dust removal cloth bag (9) in the dust removal box (3) removes dust for a long time, accumulated dust falls to the bottom of the dust removal box (3), the copper pipe opens the discharge valve pipe (6) to be discharged, and the driving connecting rod (12) is driven to descend through the operation of the driving cylinder (11), so that the driving connecting rod (12) drives the cloth bag dust removal ring (13) to move outside the dust removal cloth bag (9), and meanwhile, the dust removal cloth bag (9) is extruded to shrink, so that the dust on the inner wall of the dust removal cloth bag (9) falls off and falls downwards, and the dust is rapidly removed;
step four: when the particle catcher (18) is used for particle catching and filtering, water in the water purifying tank body (29) is sucked by the suction pump (20), then the water is conveyed to the rotary spray pipe (23) through the water output pipe (21), the water is sprayed out through the plurality of spray heads (24) on the outer side of the rotary spray pipe (23), then the water drops in the particle catcher (18), particle substances in the adhesion particle catcher (18) flow downwards, the rotary spray pipe (23) is driven to rotate around the rotary joint (22) by pressure generated by the spray heads (24), water is sprayed in a rotating mode, water carrying particles enters the water receiving disc (26) through the water guide ring (27), and then enters the water purifying tank body (29) through the circulating recovery pipe (25) to be recycled.
