[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 - Figure 2 , an embodiment provided by the present utility model: an integrated device for waste gas adsorption concentration and catalytic combustion, including a combustion chamber 1, a combustion port is opened in the combustion chamber 1, the combustion port can store waste for combustion, and the combustion exhaust gas and fly ash will enter the next process through the inside of the combustion chamber 1. An intake cap 2 is installed on the top of the combustion chamber 1, the right side of the combustion chamber 1 is fixedly connected to a treatment chamber 3, a treatment process is set up inside the treatment chamber 3, a working chamber 4 is fixedly connected inside the treatment chamber 3, the working chamber 4 is a specific treatment process area, a dissolution mechanism 5 is arranged inside the working chamber 4, an adsorption mechanism 6 is also arranged inside the working chamber 4, and an exhaust fan 7 is installed on the right side of the treatment chamber 3.

[0024] Refer to Figure 1 - Figure 3 , the dissolution mechanism 5 includes a reagent storage tank 501, a connecting pipe 502, and a first air filter plate 503. The reagent storage tank 501 is installed on the top of the treatment chamber 3, and the acidic dissolution agent stored inside the reagent storage tank 501 can dissolve the fly ash after incineration. The connecting pipe 502 is fixedly connected to the inner wall of the treatment chamber 3, and the first air filter plate 503 is fixedly connected to the inner wall of the working chamber 4. The first air filter plate 503 blocks the fly ash in the waste gas inside the working chamber 4 to prevent the fly ash from entering the next process.

[0025] Refer to Figure 1 - Figure 3, the dissolution mechanism 5 further includes a dissolution tank 504, a functional rod 505, and a spiral blade 506. The dissolution tank 504 is fixedly connected and communicated at the bottom of the working tank 4. The functional rod 505 is rotatably connected to the inner wall of the dissolution tank 504. The spiral blade 506 is fixedly connected to the surface of the functional rod 505. The rotation of the functional rod 505 drives the spiral blade 506 on its surface to rotate, stirring the fly ash dissolution liquid in the dissolution tank 504 and accelerating the fly ash dissolution efficiency. One end of the connecting pipe 502 far from the reagent storage tank 501 is fixedly connected and communicated with the top of the working tank 4. The surface of the functional rod 505 is rotatably connected to the inner wall of the working tank 4.

[0026] Referring to Figure 4 , the adsorption mechanism 6 includes a second air filter plate 601, an exhaust gas tank 602, and a folding plate 603. The second air filter plate 601 is fixedly connected to the inner wall of the working tank 4. The function of the second air filter plate 601 is roughly the same as that of the first air filter plate 503, further preventing fly ash from floating. The exhaust gas tank 602 is fixedly connected and communicated at the bottom of the working tank 4. The exhaust gas tank 602 is mainly the area for treating exhaust gas, referring to the waste gas that has been separated from the incinerated fly ash. The folding plate 603 is rotatably connected to the front of the exhaust gas tank 602. The adsorption mechanism 6 further includes a threaded groove 604, a nut sleeve 605, and a capture plate 606. The threaded groove 604 is opened on the surface of the functional rod 505. The nut sleeve 605 is installed on the surface of the threaded groove 604. The capture plate 606 is fixedly connected to the surface of the nut sleeve 605. The threaded groove 604 drives the nut sleeve 605 to move. The nut sleeve 605 drives the fiber filter material in the capture plate 606 to capture the particulate matter existing in the exhaust gas. The inner wall of the exhaust gas tank 602 is rotatably connected to the surface of the functional rod 505. The front of the folding plate 603 is fixedly communicated with the suction fan 7. The surface of the capture plate 606 is in contact with the inner wall of the exhaust gas tank 602, further improving the exhaust gas emission quality and reducing the impact of exhaust gas particulate matter on the surrounding environment.

[0027] Working principle: During use, when the operator needs to incinerate waste, the waste is placed at the incineration opening provided at the combustion box 1 for incineration. The suction fan 7 is started, and the exhaust gas and fly ash after incineration are sucked into the working box 4 inside the treatment box 3 under the action of the suction fan 7. At this time, the solvent in the solvent storage tank 501 is released into the working box 4 through the connecting pipe 502. The solvent contacts the waste ash, causing the waste ash to no longer float and fuse in the solvent and flow into the dissolution tank 504. At this time, the operator starts the device power supply, causing the function rod 505 to rotate. The rotation of the function rod 505 drives the spiral blade 506 on its surface to rotate, stirring the fly ash dissolution liquid in the dissolution tank 504, accelerating the fly ash dissolution efficiency, and making the pollutants in the fly ash more evenly distributed in the solution, which is beneficial to subsequent harmless treatment. At the same time, the exhaust gas after removing the fly ash enters the exhaust gas box 602 through the first filter plate 503 and the second filter plate 601. At this time, the thread groove 604 provided on the surface of the function rod 505 rotates, causing the thread groove 604 to drive the nut sleeve 605 to move. The nut sleeve 605 drives the fiber filter material in the capture plate 606 to capture the particulate matter existing in the exhaust gas, thereby further improving the exhaust gas emission quality and reducing the pollution and damage of the exhaust gas particulate matter to the surrounding environment.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
