[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4In this embodiment, a waste gas purification device for waste heat recovery is provided, including a box body 1, a partition 11 is fixedly connected to the inside of the box body 1, a heat exchange mechanism 4 is installed on one side of the partition 11 inside the box body 1, the heat exchange mechanism 4 includes a plurality of heat exchange cylinders 42, the heat exchange cylinders 42 form a channel inside the box body 1 for the waste gas to pass through, a cleaning mechanism 5 is installed above the heat exchange mechanism 4 inside the box body 1, the cleaning mechanism 5 includes a plurality of push blocks 54, the push blocks 54 are located above the heat exchange cylinders 42, and are used to remove impurities inside the heat exchange cylinders 42, and a filter assembly 13 is installed on the other side of the partition 11 inside the box body 1.

[0022] When in use, high-temperature exhaust gas is introduced into the box body 1. After being blocked by the partition 11, the exhaust gas can only pass through the heat exchange tube 42 and move to the other side of the partition 11, and then be discharged from the box body 1 after being filtered by the filter component 13. When the exhaust gas passes through the heat exchange tube 42, the heat in the exhaust gas is contacted by the heat exchange tube 42, thereby absorbing the heat in the exhaust gas to avoid the waste of heat in the exhaust gas. When impurities in the exhaust gas remain in the heat exchange tube 42, the push block 54 in the cleaning mechanism 5 descends through the heat exchange tube 42 to take the impurities out of the heat exchange tube 42.

[0023] A plurality of fins may be provided in the heat exchange tube 42 to increase the heat exchange area. The fins need to be arranged circumferentially on the inner circumference of the heat exchange tube 42 , and the push block 54 needs to be provided with slots corresponding to the fins.

[0024] In further embodiments, see Figures 2-3 The heat exchange mechanism 4 includes a connecting plate 41, a guide baffle 12 is fixedly connected inside the box 1, and the connecting plate 41 is transversely located between the guide baffle 12 and the baffle 11. A plurality of heat exchange tubes 42 vertically penetrate the connecting plate 41, and a heat conducting plate 43 is connected to one side of the heat exchange tube 42. One end of the heat conducting plate 43 transversely passes through the guide baffle 12. A water pipe 44 is longitudinally installed on the heat conducting plate 43, and both ends of the water pipe 44 pass through the box 1 and are located outside the box 1. The inside of the box 1 is separated by the baffle 11, the connecting plate 41 and the guide baffle 12, so that the exhaust gas can only enter the other side of the baffle 11 through the heat exchange tube 42. The exhaust gas can only enter the heat exchange tube 42 during the flow process. The heat exchange tube 42 transfers the absorbed heat to the water pipe 44 through the heat conducting plate 43, and the circulating water flow is passed through the inside of the water pipe 44, thereby taking away the heat on the heat conducting plate 43.

[0025] In further embodiments, see Figure 4The cleaning mechanism 5 includes a housing 51, and a lifting plate 52 is connected to the housing 51 so as to slide up and down. A plurality of connecting rods 53 are fixedly connected to the lower end of the lifting plate 52, and a push block 54 is fixed below the connecting rod 53. The lifting plate 52 is lowered to drive the plurality of connecting rods 53 to be lowered, and the push block 54 at the lower end of the connecting rod 53 is lowered to be inserted into the heat exchange tube 42. The push block 54 is fitted with the inside of the heat exchange tube 42 to push the impurities in the heat exchange tube 42 out from the bottom of the heat exchange tube 42, so as to prevent the impurities from being adsorbed on the inner wall of the heat exchange tube 42, resulting in a decrease in heat exchange efficiency.

[0026] In further embodiments, see Figure 2 The upper end of the guide baffle 12 is bent and inclined, and the upper end slope of the guide baffle 12 is higher than the upper end of the heat exchange tube 42. The exhaust gas entering the interior of the box 1 is guided to the upper part of the heat exchange tube 42 through the guide baffle 12, so that the exhaust gas can smoothly enter the heat exchange tube 42.

[0027] In further embodiments, see Figure 4 A driving mechanism is fixedly installed on one side of the housing 51, and the driving mechanism includes a motor, and a screw rod is fixedly connected to the upper end of the motor, and the screw rod passes through the lifting plate 52 and is threadedly connected to the lifting plate 52. The motor is started to drive the screw rod to rotate, and the screw rod rotates to drive the lifting plate 52 to move up and down, so that the lifting plate 52 descends to complete the cleaning work.

[0028] In further embodiments, see Figure 2 A cleaning box 6 is inserted transversely below the heat exchange mechanism 4 in the box body 1, and a push block 54 can be inserted into the cleaning box 6. The cleaning box 6 is filled with a clean solvent, and when the push block 54 is lowered, it is inserted into the cleaning box 6, and the push block 54 is cleaned by the clean solvent to reduce the residual impurities on the push block 54. At the same time, the cleaning box 6 is inside the box body 1, and the residual temperature of the exhaust gas after cooling can make the solvent in the cleaning box 6 in a warm state, which can further improve the ability to dissolve impurities.

[0029] In further embodiments, see Figure 1 An air inlet pipe 2 is fixedly connected to one side of the upper end of the box body 1, and an air outlet pipe 3 is installed on the other side of the box body 1. The air inlet pipe 2 is connected to the pipeline for exhaust gas access, and the exhaust gas after cooling and purification is discharged through the air outlet pipe 3.
