[0003] Among them, through retrieval, a Chinese patent with the publication number of CN220958486U discloses a waste incineration waste heat recovery system. The above patent realizes the function of flue gas filtration with a structural scheme combining a quartz sand filter layer and a filter plate. However, since the flue gas cannot be preliminarily filtered, a large amount of particulate impurities are easily attached and accumulated on the surfaces of the quartz sand filter layer and the filter plate, resulting in a reduction in the flue gas treatment efficiency. Therefore, for the progress of the industry technology, to better realize the function of flue gas treatment and improve the core technology competitiveness, this application proposes a new implementation scheme different from the particulate matter adsorption device structure in the existing incinerator flue gas. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problem that a large amount of particulate impurities are easily attached and accumulated on the surfaces of the quartz sand filter layer and the filter plate in the existing recovery system, resulting in a reduction in the flue gas treatment efficiency, and to propose a particulate matter adsorption device for incinerator flue gas.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A particulate matter adsorption device for incinerator flue gas includes a primary filter box and a secondary filter box. A smoke inlet pipe is inserted into the top of the primary filter box, a connecting pipe is inserted between the primary filter box and the secondary filter box, a transparent water box is threadedly inserted into the bottom end of the primary filter box, and a smoke outlet pipe is inserted into one side of the secondary filter box. A filter assembly is arranged in the secondary filter box. The filter assembly includes a hollowed-out plate which is clamped in the secondary filter box. A lower filter screen is clamped in the hollowed-out plate. A bearing frame is fixedly connected to the top of the hollowed-out plate. An activated carbon adsorption layer is arranged in the bearing frame. An upper filter screen is arranged on the top of the activated carbon adsorption layer.
[0007] Further, a sealing door is clamped on one side of the secondary filter box.
[0008] Further, an inclined plate is fixedly connected to one side inner wall of the primary filter box, and the inclined plate is located at one end of the connecting pipe.
[0009] Further, one outer wall of the primary filter box is fixedly connected with a motor, the output end of the motor passes through one side of the primary filter box and is connected with a rotating shaft through a coupling, and a plurality of baffle plates are fixedly connected to the outer wall of the rotating shaft.
[0010] Further, a water inlet pipe is inserted into one side of the primary filter box.
[0011] Further, a water outlet pipe is inserted into one side of the transparent water box.
[0012] The beneficial effects of the present utility model are as follows:
[0013] 1. The flue gas is input from the smoke inlet pipe into the primary filter box, and part of the particulate impurities fall into the water in the transparent water box, thereby preliminarily filtering the flue gas and improving the treatment efficiency of the flue gas.
[0014] 2. Driven by the motor, the rotating shaft rotates, thereby driving the baffle plates to rotate, and further stirring the water in the transparent water box, thereby avoiding the formation of a floating layer on the water surface in the transparent water box, so as not to affect the filtration efficiency of the flue gas.
[0015] 3. The flue gas passes through the upper filter net, thereby filtering the flue gas again. Then, the flue gas passes through the activated carbon adsorption layer to adsorb harmful gases in the flue gas, and then the particulate impurities in the flue gas are further filtered through the lower filter net, improving the treatment effect of the flue gas.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0022] Referring to Figures 1-4 , a particulate matter adsorption device for incinerator flue gas includes a primary filter box 1 and a secondary filter box 3. A smoke inlet pipe 6 is inserted into the top of the primary filter box 1. A connecting pipe 2 is inserted between the primary filter box 1 and the secondary filter box 3. A transparent water box 4 is threadedly inserted into the bottom end of the primary filter box 1. Flue gas is input into the primary filter box 1 from the smoke inlet pipe 6. Some particulate impurities fall into the water in the transparent water box 4. A smoke outlet pipe 7 is inserted into one side of the secondary filter box 3. A filter assembly 5 is provided in the secondary filter box 3. The filter assembly 5 includes a hollowed-out plate 501, which is clamped in the secondary filter box 3. A lower filter net 503 is clamped in the hollowed-out plate 501. A bearing frame 502 is welded to the top of the hollowed-out plate 501. An activated carbon adsorption layer 504 is provided in the bearing frame 502. The flue gas passes through the activated carbon adsorption layer 504 to adsorb harmful gases in the flue gas. An upper filter net 505 is provided on the top of the activated carbon adsorption layer 504. The flue gas passes through the upper filter net 505, thereby filtering impurities in the flue gas.
[0023] A sealing door 8 is clamped on one side of the secondary filter box 3. By opening the sealing door 8, it is convenient to clean the secondary filter box 3. An inclined plate 9 is fixed to the inner wall of one side of the primary filter box 1 by bolts. The inclined plate 9 is located at one end of the connecting pipe 2, so that the flue gas passes through the transparent water box 4 and then discharges from the connecting pipe 2, so as not to affect the treatment effect of the flue gas. A motor 14 is fixed to the outer wall of one side of the primary filter box 1 by bolts. The output end of the motor 14 passes through one side of the primary filter box 1 and is connected to a rotating shaft 10 through a coupling. A plurality of baffle plates 11 are fixed to the outer wall of the rotating shaft 10 by bolts. Driven by the motor 14, the rotating shaft 10 rotates, thereby driving the baffle plates 11 to rotate, and then stirring the water in the transparent water box 4, thereby preventing a floating layer from forming on the water surface in the transparent water box 4. A water inlet pipe 13 is inserted into one side of the primary filter box 1, so as to facilitate injecting water into the transparent water box 4 from the water inlet pipe 13. A water outlet pipe 12 is inserted into one side of the transparent water box 4, so as to facilitate discharging the water in the transparent water box 4.
[0024] The working principle of this embodiment is as follows: when in use, water is injected into the transparent water box 4 from the water inlet pipe 13, and then the smoke is input into the primary filter box 1 from the smoke inlet pipe 6, and some particulate impurities fall into the water in the transparent water box 4, and the rotating shaft 10 is rotated under the drive of the motor 14, thereby driving the paddle 11 to rotate, and then the water in the transparent water box 4 is moved, thereby avoiding the formation of a floating layer on the water surface in the transparent water box 4, and then the smoke is input into the secondary filter box 3 from the connecting pipe 2, and the smoke passes through the upper filter screen 505, thereby filtering the smoke again, and then the smoke passes through the activated carbon adsorption layer 504 to adsorb harmful gases in the smoke, and then the particulate impurities in the smoke are further filtered through the lower filter screen 503, and finally, discharged from the smoke outlet pipe 7.
