[0015] A process for treating incineration tail gas comprises the following steps:

[0016] S1. During use, first turn on the control power of the servo motor, and the servo motor drives multiple rotating boxes to form synchronous rotation in the processing chamber. The combustion chamber is used as a space for burning incineration materials. The incineration materials are filled into the combustion chamber from the furnace mouth to form combustion. The smoke generated during the combustion process will be drawn out from the exhaust pipe on the combustion chamber;

[0017] S2. Due to the synchronous rotation of the multiple rotating boxes, the multiple elastic toggling members will move relative to the inner push arc plate and the outer push arc plate, and under the alternating and repeated pushing action of the multiple inner push arc plates and the multiple outer push arc plates, the elastic toggling members will push the gas transfer piston to form multiple reciprocating movements in the gas transfer bin. When the air inlet is connected to the exhaust pipe, the gas transfer piston in the rotating box rotated to the corresponding position is pushed to the area away from the exhaust pipe, that is, the space of the gas transfer bin part on the side close to the exhaust pipe of the gas transfer piston is increased, so that the exhaust gas in the combustion bin is sucked into the gas transfer bin, while the space of the gas transfer bin part on the side away from the exhaust pipe of the gas transfer piston is reduced, so that the exhaust gas existing in the gas transfer bin is squeezed and discharged outward;

[0018] S3. When the connection between the air inlet and the exhaust pipe is misaligned due to the rotation of the rotating box, a closed space is formed between the rotating piston and the space on the side close to the exhaust pipe. Then, in the process of the rotating piston moving close to the exhaust pipe under the matching effect of the corresponding outward-pushing arc plate, due to the action of the one-way valve, the exhaust gas in the partial space of the rotating gas bin on the side close to the exhaust pipe and the exhaust pipe will pass through the connecting hole and enter the partial space of the rotating gas bin on the side away from the exhaust pipe and the rotating gas piston. Thereafter, when the elastic toggle member is pushed by the inward-pushing arc plate again and the rotating gas piston moves in the rotating gas bin toward the side away from the exhaust pipe, the exhaust gas in the partial space of the rotating gas bin on the side away from the exhaust pipe and the rotating gas piston will be compressed and enter the multi-stage reciprocating treatment mechanism, and accompanied by the sequential rotation of multiple rotating boxes, a repeated entry and exit of the multi-stage reciprocating treatment mechanism is formed to form exhaust gas treatment;

[0019] S4. When the rotating box forms a rotation cycle in the processing chamber, that is, when the exhaust port of the rotating box is connected to the external duct again, the exhaust chamber in the rotating box will re-inhale the exhaust gas in the combustion chamber, and the exhaust gas in the exhaust chamber treated by the multi-stage reciprocating treatment mechanism will be squeezed and sent into the external duct to be discharged externally. In this way, continuous quantitative extraction and treatment of exhaust gas is formed by reciprocating movement, which ensures the relative independence of each process and improves the controllability of exhaust gas treatment between each process.

[0020] Compared with the prior art, the present invention provides an incineration tail gas treatment system and treatment process, which has the following beneficial effects:

[0021] (1) In the present invention, through the design of the treatment device, on the one hand, a multi-stage reciprocating treatment mechanism is provided to form a spatial structure installed relative to the combustion furnace body, and on the other hand, a corresponding transfer drive system is formed to form a corresponding incineration exhaust gas, which can realize continuous quantitative extraction and treatment of the exhaust gas, so as to facilitate the injection drive of the exhaust gas relative to the multi-stage reciprocating treatment mechanism.

[0022] (2) In the present invention, through the design of a multi-stage reciprocating treatment mechanism, the continuous quantitative extraction and treatment of the supporting exhaust gas forms a plurality of injectable purification spaces. During the exhaust gas treatment process, each process is connected and relatively independent, and the exhaust gas treatment between each process is well controllable.

[0038] The servo motor 7 in this embodiment is a conventional device known to those skilled in the art and purchased on the market. In the present invention, we only use it without improving its structure and function. For those skilled in the art, its setting method, installation method and electrical connection method only need to be debugged and operated according to the requirements of its instruction manual, and will not be described in detail here. The combustion furnace body 1 is equipped with ignition and gas supply functions to ensure the ignition of the incineration material and the supply of oxygen during the combustion process. For the filter, it can be selected in a targeted manner according to the specific range of the incineration material, which can be one type, multiple types or partially multiple types.

[0039] In summary, the working principle of the incineration tail gas treatment system and treatment process is that when in use, the control power of the servo motor 7 is first turned on, and the servo motor 7 drives multiple rotating boxes 8 to form a synchronous rotation movement in the treatment chamber 5. The combustion chamber 2 is used as a space for burning incineration materials. The incineration materials are filled into the combustion chamber 2 from the furnace mouth to form combustion. The smoke generated during the combustion process will be drawn out from the exhaust pipe 4 on the combustion chamber 2. Due to the synchronous rotation movement of the multiple rotating boxes 8, the multiple elastic toggles will be relative to the inner push arc plate 13 and the outer push arc plate 13. The push arc plates 14 are in relative motion, and under the alternating and repeated pushing action of multiple inner push arc plates 13 and multiple outer push arc plates 14, the elastic toggle member will push the gas transfer piston 10 to form multiple reciprocating motions in the gas transfer bin 9. When the air inlet 15 is connected with the exhaust pipe 4, the gas transfer piston 10 in the rotating box 8 that is rotated to the corresponding position is pushed to the area away from the exhaust pipe 4, that is, the space between the gas transfer piston 10 and the gas transfer bin 9 on the side close to the exhaust pipe 4 is increased, so that the exhaust gas in the combustion bin 2 is sucked into the gas transfer bin 9, and the gas transfer The space of the gas transfer chamber 9 on the side away from the piston 10 and the exhaust pipe 4 is reduced, so that the exhaust gas in the gas transfer chamber 9 is squeezed out. When the connection between the air inlet 15 and the exhaust pipe 4 is misaligned due to the rotation of the rotating box 8, the gas transfer piston 10 and the space on the side close to the exhaust pipe 4 form a closed space. After that, in the process of the gas transfer piston 10 moving close to the exhaust pipe 4 under the matching effect of the corresponding outward arc plate 14, due to the effect of the one-way valve 12, the gas transfer piston 10 and the gas transfer chamber 9 on the side close to the exhaust pipe 4 are closed. The exhaust gas will pass through the connecting hole 11 and enter the part of the space of the gas transfer bin 9 on the side away from the exhaust pipe 4 while the elastic push piece is pushed by the inner push arc plate 13 again, and the gas transfer piston 10 moves in the gas transfer bin 9 toward the side away from the exhaust pipe 4. The exhaust gas in the part of the space of the gas transfer bin 9 on the side away from the exhaust pipe 4 will be compressed and enter the multi-stage reciprocating treatment mechanism, and accompanied by the sequential rotation of multiple rotating boxes 8, it will form a repeated entry and exit of the multi-stage reciprocating treatment mechanism to form the treatment of the exhaust gas.

[0040] Furthermore, due to the movement of the gas conversion piston 10, when the tail gas is pressed into the end of the outer inflection hole 32 connected to the gas conversion chamber 9, as shown in the attached Figure 5As shown in the opening position of the air inlet hole 41, with the increase of the air pressure in the outer inflection hole 32, the exhaust gas with increased pressure will pass through the air inlet hole 41 and be sent into the space formed by the fixed cylinder 33 and the telescopic cylinder 37. As the air pressure in the space formed by the fixed cylinder 33 and the telescopic cylinder 37 increases, the telescopic cylinder 37 will overcome the elastic force of the stabilizing spring 38 and slide relative to the fixed cylinder 33. Due to the transmission effect between the driving rod 39 and the spiral groove 40 on the telescopic cylinder 37, the driving rod 39 that is synchronously displaced with the fixed cylinder 33 will realize the rotation adjustment of the rotating block 34, so that the inner inflection hole 35 and the outer inflection hole 32 are connected to each other. In this state, the The squeezed exhaust gas will enter the elastic bag 27 through the filter, and the volume of the elastic bag 27 will increase to increase the exhaust gas storage space. When the reverse movement of the gas transfer piston 10 fails to squeeze the exhaust gas into the outer inflection hole 32, the stabilizing spring 38 controls the rotating block 34 to rotate and reset in the opposite direction, that is, the stabilizing spring 38 is at its natural length, and the inner inflection hole 35 and the outer inflection hole 32 are rotated and misaligned with each other, and the exhaust gas cannot pass through the filter. When the gas transfer piston 10 continues to move and a negative pressure is formed at one end of the outer inflection hole 32 connected to the gas transfer bin 9, the air pressure in the space formed by the fixed cylinder 33 and the telescopic cylinder 37 is reduced, causing the reverse rotation of the rotating block 34. The filter element 34 is driven by the spring 38 to form a coordinated adjustment with the flow direction of the exhaust gas, so that the exhaust gas entering the elastic bag 27 and the exhaust gas exiting the elastic bag 27 form a unidirectional flow in the same direction relative to the filter element, thereby preventing the impurities that have been filtered out of the filter element from being blown out due to the reverse flow of the exhaust gas, and the filter element from causing secondary pollution to the exhaust gas, thereby ensuring the reliability of exhaust gas filtration. For the rotation limit of the rotating block 34, if the stabilizing spring 38 is in the natural state as the 0 point, the rotation limit of the rotating block 34 can be marked as ±90°, that is, when the rotating block 34 is in the state of near +90° rotation and near -90° rotation, the inner inflection hole 35 and the outer inflection hole 32 are both It is in a connected state, the difference is that the head and tail connections between the inner inflection hole 35 and the outer inflection hole 32 are alternately converted, and the entire rotatable range of the rotating block 34 is 180°. When the rotating box 8 forms a 360° rotation cycle in the processing chamber 5, that is, when the exhaust port 16 of the rotating box 8 is connected with the external lead-in pipe 17 again, the exhaust chamber 9 in the rotating box 8 will re-inhale the exhaust gas in the combustion chamber 2, and the exhaust gas in the exhaust chamber 9 treated by the multi-stage reciprocating treatment mechanism will be squeezed into the external lead-in pipe 17 to form an external discharge, so that the continuous quantitative extraction and treatment of the exhaust gas is formed reciprocatingly, which ensures the relative independence of each process and improves the controllability of the exhaust gas treatment between each process.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

5. A process for treating incineration tail gas, characterized in that: An incineration tail gas treatment system according to any one of claims 1 to 4 is used, comprising the following steps: S1. During use, firstly, the control power supply of the servo motor (7) is turned on, and the servo motor (7) drives the plurality of rotating boxes (8) to form a synchronous rotating motion in the processing chamber (5). The combustion chamber (2) serves as a space for burning the incineration material. The incineration material is filled into the combustion chamber (2) from the furnace mouth to form combustion, and the smoke generated during the combustion process is drawn out from the exhaust pipe (4) on the combustion chamber (2); S2. Due to the synchronous rotation of the plurality of rotating boxes (8), the plurality of elastic toggle members will move relative to the inner push arc plate (13) and the outer push arc plate (14), and under the alternating and repeated pushing action of the plurality of inner push arc plates (13) and the plurality of outer push arc plates (14), the elastic toggle members will push the gas transfer piston (10) to form multiple reciprocating movements in the gas transfer bin (9). When the air inlet (15) is connected to the exhaust pipe (4), the gas transfer piston (10) in the rotating box (8) rotated to the corresponding position is pushed to a region away from the exhaust pipe (4), that is, the space of the gas transfer bin (9) on the side close to the exhaust pipe (4) of the gas transfer piston (10) is increased, so that the exhaust gas in the combustion bin (2) is sucked into the gas transfer bin (9), while the space of the gas transfer bin (9) on the side away from the exhaust pipe (4) of the gas transfer piston (10) is reduced, so that the exhaust gas existing in the gas transfer bin (9) is squeezed and discharged; S3. When the connecting portion between the air inlet (15) and the exhaust pipe (4) is misaligned due to the rotation of the rotating box (8), the space near the exhaust pipe (4) and the rotating piston (10) is closed. Then, in the process of the rotating piston (10) moving near the exhaust pipe (4) under the matching effect of the corresponding outward arc plate (14), the exhaust gas in the space of the rotating chamber (9) near the exhaust pipe (4) passes through the connecting hole (11) and enters the rotating piston (10) due to the effect of the one-way valve (12). The gas transfer piston (10) is located in a part of the space of the gas transfer bin (9) on the side away from the exhaust pipe (4). When the elastic toggle member is pushed by the inner arc plate (13) again, the gas transfer piston (10) moves in the gas transfer bin (9) toward the side away from the exhaust pipe (4). The exhaust gas in the part of the space of the gas transfer bin (9) on the side away from the exhaust pipe (4) is compressed and enters the multi-stage reciprocating treatment mechanism. The multiple rotating boxes (8) rotate in sequence, and the exhaust gas is repeatedly entered and exited from the multi-stage reciprocating treatment mechanism, thereby treating the exhaust gas. S4. After the rotating box (8) forms a rotation cycle in the processing chamber (5), that is, when the exhaust port (16) of the rotating box (8) is connected to the external lead pipe (17) again, the exhaust chamber (9) in the rotating box (8) will re-inhale the exhaust gas in the combustion chamber (2), and the exhaust gas in the exhaust chamber (9) treated by the multi-stage reciprocating treatment mechanism will be squeezed and sent into the external lead pipe (17) to be discharged externally, so that the exhaust gas is continuously and quantitatively extracted and treated by reciprocating in this way.
