[0033] The specific arrangement and function of the cleaning device 8 and the stirring device 9 will be described in detail below.

[0034] like Figure 1-Figure 4 As shown, the cleaning device 8 includes an electric telescopic rod 801, which is fixedly connected to the inner wall of the air intake box 2, and the output end of the electric telescopic rod 801 is fixedly connected to a moving plate 802, and two connecting rods 803 are fixedly connected to both sides of the moving plate 802, and the four connecting rods 803 are fixedly connected to the side close to the electrostatic adsorption plate 5. Scraping blades 804 are fixedly connected. By setting the electric telescopic rod 801, the moving plate 802 can be controlled to drive the connecting rod 803 to move, so that the connecting rod 803 drives the scraper 804 to move on the surface of the electrostatic adsorption plate 5, so as to achieve the cleaning effect of the electrostatic adsorption plate 5. Both ends of the scraper 804 are fixedly connected with baffles 805, and the inner wall of the air intake box 2 is slidably connected to two collecting boxes 806. By setting the collecting box 806, the cleaned impurities can be collected, and by setting the baffle 805, the impurities can be guaranteed to fall into the collecting box 806 as much as possible.

[0035] The two collecting boxes 806 are fixedly connected to the side away from each other with a sealing plate 807, and the sealing plate 807 is glued to the side close to the collecting box 806 with a sealing ring 808, and the sealing ring 808 is made of rubber. The side of the sealing plate 807 away from the air intake box 2 is fixedly connected to the first fixing plate 810. By setting the sealing plate 807, the air intake box 2 can be closed while the collecting box 806 is moved, and the sealing ring 808 can be provided to increase the sealing effect of the air intake box 2. The sealing plate 807 is fixedly connected to the side close to the first fixing plate 810 with a handle 809, and the two sides of the air intake box 2 are fixedly connected with the second fixing plate 811, and the inner wall of the second fixing plate 811 is threadedly inserted with a fastening screw 812. By setting the handle 809, the sealing plate 807 can be easily moved, and by setting the fastening screw 812, the first fixing plate 810 and the second fixing plate 811 can be connected, so as to limit the position of the sealing plate 807.

[0036] like Figure 2 and Figure 5 as well as Figure 6 As shown, the stirring device 9 includes a motor 91, which is fixedly connected to the side of the base 1 away from the treatment box 3, and the output end of the motor 91 is fixedly connected to a rotating rod 92, which is rotatably connected to the base 1 and the inner wall of the treatment box 3, and the end of the rotating rod 92 away from the motor 91 is fixedly connected to a stirring rod 94. By setting the motor 91, the rotating rod 92 and the stirring rod 94 can be driven to rotate, so that the stirring rod 94 can be used to stir the water in the treatment box 3, thereby increasing the efficiency of waste heat recovery.

[0037] The inner wall of the treatment box 3 is fixedly connected with a cylinder 93, and a rotor 96 is fixedly connected to the side of the cylinder 93 close to the air pipe 10. By setting the cylinder 93, the water in the treatment box 3 can be divided into two parts, so that the contact between the water and the air pipe 10 can be ensured as much as possible during the stirring of the water. A water inlet 97 is opened on the surface of the cylinder 93, and a closing block 95 is fixedly connected to the side of the cylinder 93 close to the rotor 96. By setting the closing block 95, it can be ensured that the water flows through the surface of the rotor 96, and by setting the closing block 95 and the rotor 96, the water flow can be guided.

[0038] Working principle: After the exhaust gas is burned, the treated exhaust gas is introduced into the air inlet box 2 on the base 1, the waste heat recovery device is connected to the external power supply, and then the electrostatic generator 4 is started to make the electrostatic adsorption plate 5 adsorb the impurities contained in the exhaust gas. After that, the exhaust gas passes through the first filter plate 6 and the second filter plate 7 for further impurity removal. The filtered exhaust gas enters the treatment box 3 through the air pipe 10. After the waste heat of the exhaust gas is recovered in the treatment box 3, the exhaust gas can be discharged. After the waste heat recovery device is used, the electric telescopic rod 801 is started, and the electric telescopic rod 801 drives the connecting rod 803 through the moving plate 802, so that the scraper 804 cleans the surface of the electrostatic adsorption plate 5. At the same time, under the cover of the baffle 805, it is guaranteed as much as possible that the impurities on the electrostatic adsorption plate 5 can fall into the collection box 806. When it is necessary to clean the collection box 806, the fastening screw 812 is rotated to make it rotate on the inner wall of the second fixed plate 811, so that the fastening screw 812 is away from the first fixed plate 810, and the restriction on the position of the sealing plate 807 is released. Grab the handle 809, move the collection box 806 away from the air intake box 2, and after cleaning the collection box 806, move the collection box 806 close to the air intake box 2, and turn the fastening screw 812 to fix the position of the sealing plate 807. By setting the sealing ring 808, the reliability of the sealing of the sealing plate 807 to the air intake box 2 can be increased. By setting the cleaning device 8, the electrostatic adsorption plate 5 can be cleaned after the waste heat recovery device is used, thereby avoiding the accumulation of impurities on the surface of the electrostatic adsorption plate 5 as much as possible, which will affect the performance of the electrostatic adsorption plate 5.

[0039] When the waste heat recovery device is used, the starting motor 91 drives the rotating rod 92 to rotate on the inner wall of the base 1 and the treatment box 3, thereby driving the stirring rod 94 to rotate. The rotation of the stirring rod 94 can drive the water entering the cylinder 93 from the water inlet 97 to rotate, thereby accelerating the flow of water on the surface of the air pipe 10. At the same time, the rotating water flow is blocked by the closing block 95 and flows out of the cylinder 93 through the vane 96, thereby realizing the circulation of water inside and outside the cylinder 93. By setting up the stirring device 9, the water near the air pipe 10 can be stirred, thereby accelerating the flow of water on the surface of the air pipe 10, and further increasing the absorption of the surface temperature of the air pipe 10 as much as possible, thereby improving the efficiency of absorbing waste heat from exhaust gas.
