seventhly, after the collection device works each time, placing each connecting cylinder 232 in an inverted mode, flushing water from the bottom end of each connecting cylinder 232 to the inside, removing pollutants remained in the connecting cylinders 232, introducing clean water into the liquid inlet pipe 11 in the spraying mechanism 1, enabling the clean water to enter the liquid distribution pipe 12 through the liquid inlet pipe 11, enabling the liquid distribution pipe 12 to send the clean water into each spraying pipe 14 through each liquid guide pipe 13, spraying the clean water into the collection box 4 through the spraying pipes 14, cleaning the top surface of the partition plate 7 and each air filtering component 23 in the collection mechanism 2 through the clean water, enabling the clean water to flow through the inside of the collection mechanism 2, finally discharging the clean water through the hopper 31 and the discharge pipe 32, and performing centralized purification treatment on the discharged clean water.

And those not described in detail in this specification are well within the skill of those in the art.

The method of the flue gas pollutant collecting device comprises the following steps:

connecting a flue gas conveying pipe with the top end of the gas inlet pipe 5 through a flange plate, connecting a flue gas treatment liquid conveying pipe with one end of a liquid inlet pipe 11 of the spraying mechanism 1, and connecting a gas inlet end of a sampling pump with one end of a gas outlet pipe 6 positioned outside the collecting box 4;

flue gas enters the upper part of the inner part of the collection box 4 through the gas inlet pipe 5, meanwhile, flue gas treatment liquid enters the liquid distribution pipe 12 through the liquid inlet pipe 11, the flue gas treatment liquid in the liquid distribution pipe 12 respectively enters the inner parts of the plurality of spray pipes 14 through the plurality of liquid guide pipes 13, then, the flue gas treatment liquid is sprayed on the upper part of the inner part of the collection box 4 through the spray holes 15 formed in the lower part of the surface of each spray pipe 14, the flue gas above the inner part of the collection box 4 is purified through the sprayed flue gas treatment liquid, and the flue gas treatment liquid adsorbs dust and solid pollutants in the flue gas;

the flue gas treated by the flue gas treatment liquid and the waste liquid containing flue gas pollutants enter the plurality of gas filtering assemblies 23 through the through holes 8 in the partition plates 7;

the treated flue gas penetrates through the filter screen cylinder 233 in the gas filtering component 23 and the activated carbon in the filter screen cylinder 233, the flue gas enters the lower part of the acquisition mechanism 2, the sampling pump sucks the flue gas below the acquisition mechanism 2 through the gas outlet pipe 6, and waste liquid containing flue gas pollutants simultaneously enters the inside of the gas filtering component 23;

the waste liquid enters the inside of the filter screen cylinder 233, solid pollutants contained in the waste liquid are blocked by the filter screen cylinder 233, the waste liquid is treated by using activated carbon in the filter screen cylinder 233, finally the waste liquid passes through the gauze 234 at the bottom end of the connecting cylinder 232 and flows to the lower part of the inside of the collection box 4, and the treated waste liquid enters the inside of the collection box 33 through the discharge pipe 32;

opening the two sealing movable doors 22 on the front surface of the collection box 4, connecting the inner part of the fixed cylinder 231 in the air filtering assembly 23 with the surface of the connecting cylinder 232 in a threaded manner, taking out the connecting cylinder 232 in each air filtering assembly 23, placing each connecting cylinder 232 upside down, pouring out the solid smoke pollutants in the connecting cylinder 232, and completing collection and treatment of the smoke pollutants;

after the work of collection system at every turn is accomplished, place every connecting cylinder 232 handstand, wash by water to inside from the bottom of connecting cylinder 232, clear away the inside remaining pollutant of connecting cylinder 232, then through leading in the clear water to the feed liquor pipe 11 in the mechanism 1 that sprays, the clear water passes through feed liquor pipe 11 and gets into in dividing liquid pipe 12, divide liquid pipe 12 to send the clear water into every shower 14 through every catheter 13 after that, shower 14 sprays the clear water in the inside of collection box 4, utilize the clear water to clear up the top surface of baffle 7 and every filtration gas subassembly 23 in the mechanism 2 of collection, the clear water flows through the inside of collection mechanism 2, the final clear water passes through hopper 31, discharging pipe 32 discharges, carry out centralized purification to the clear water of discharging.
