[0024] Reference Figure 1-5 , the utility model embodiment of a thermal waste heat recovery system, which includes: a water storage tank 1, the upper and lower surfaces of the water storage tank 1 are respectively fixedly connected with a cold water supply tank 3 and a hot water collection tank 10, the upper surface of the water storage tank 1 is fixedly connected with a reinforcement bracket 4, the upper surface of the reinforcement bracket 4 is fixedly connected to the lower surface of the cold water supply tank 3, the left inner wall of the water storage tank 1 is fixedly connected with a built-in air guide pipe 18, the right end of the built-in air guide pipe 18 passes through the right wall of the water storage tank 1, the above devices cooperate with each other, directly use the water source to recover the waste heat of the exhaust gas, and the exhaust gas produces water droplets after contacting the low temperature, and the produced water droplets can absorb the impurities carried by the exhaust gas, so as to concentrate a large amount of impurities that can be attached to the inner wall in the part of the water storage tank 1, reduce the working intensity of the clean waste heat recovery system, and the right surface of the hot water collection tank 10 is fixedly connected with a reinforcement buckle 13, the reinforcement buckle 13 is clamped with the lower end of the side surface of the drain pipe 12, and the reinforcement buckle 13 improves the stability of the drain pipe 12.

[0025] The right end of the built-in air duct 18 is threadedly connected to the external air duct 7, and the right end of the external air duct 7 is fixedly connected to the secondary treatment chamber 8. The secondary treatment chamber 8 is a commonly used waste heat recovery equipment and exhaust gas purification equipment, which improves the waste heat recovery effect and avoids exhaust gas pollution of the environment. The lower surfaces of the water tank 1 and the secondary treatment chamber 8 are fixedly connected with multiple support rods 5, and the length of each support rod 5 is inconsistent, which is convenient for the staff to better install the waste heat recovery system according to the situation of the installation site.

[0026] An exhaust gas inlet pipe 2 is fixedly connected to the side surface of the built-in air guide pipe 18, and the lower end of the exhaust gas inlet pipe 2 passes through the lower surface of the water tank 1. A drain pipe 12 is fixedly connected to the middle part of the side surface of the built-in air guide pipe 18, and the lower end of the drain pipe 12 passes through the lower surface of the water tank 1. The existence of the drain pipe 12 changes the flatness of the built-in air guide pipe 18, and the built-in air guide pipe 18 forms a concave structure in the middle part, and the position of the drain pipe 12 is lower than the left and right ends of the built-in air guide pipe 18, which can improve the effect of collecting water sources.

[0027] The drain pipe 12 and the built-in air guide pipe 18 are both structures with one end through them. A guide pipe 15 is fixedly connected to the right side of the side surface of the drain pipe 12. The surface of the guide pipe 15 is in close contact with the lower surface of the water storage tank 1. The right end of the guide pipe 15 is fixedly connected to a wastewater collection tank 14. The existence of the wastewater collection tank 14 facilitates the recovery of water droplets attached with impurities. The lower surfaces of the hot water collection tank 10 and the wastewater collection tank 14 are both fixedly connected to a reinforcement plate 11. The surface of the reinforcement plate 11 is fixedly connected to the surface of the support rod 5. The reinforcement plate 11 improves the stability of the hot water collection tank 10 and the wastewater collection tank 14, and effectively prevents the hot water collection tank 10 and the wastewater collection tank 14 from being affected by gravity.

[0028] A sealer 6 is fixedly connected to the lower inner wall of the drain pipe 12, and the sealing part of the sealer 6 is located directly above the guide tube 15. The sealer 6 is composed of a sealing gasket 17 and a spring rod 19. The side surface of the sealing gasket 17 is in close contact with the inner wall of the drain pipe 12. The existence of the sealer 6 prevents the exhaust gas from entering the interior of the wastewater collection box 14 through the drain pipe 12. Two pressure sensors 9 are fixedly connected to the lower surface of the sealing gasket 17. The two pressure sensors 9 are relatively distributed front and back. The pressure sensors 9 are convenient for detecting the stress condition of the sealing gasket 17. An alarm 16 is fixedly connected to the lower surface of the drain pipe 12. The alarm 16 is electrically connected to the pressure sensor 9. The alarm 16 is composed of a signal receiver and a speaker, which can receive the information sent by the pressure sensor 9 and sound an alarm, so as to remind the staff to clean and maintain the components inside the drain pipe 12.

[0029] Working principle: the exhaust gas enters the interior of the built-in air guide pipe 18 through the exhaust gas inlet pipe 2. When the exhaust gas inlet pipe 2 is connected to the exhaust gas, the cold water supply tank 3 is opened to provide cold water for the water storage tank 1 to absorb the waste heat of the exhaust gas. The exhaust gas produces water droplets after contacting the low temperature. The produced water droplets can absorb the impurities carried in the exhaust gas. The water droplets are affected by the structure of the built-in air guide pipe 18 that is concave in the middle and cooperate with the drainage pipe 12 and the guide pipe 15 to transfer the water droplets that absorb the impurities to the interior of the wastewater collection box 14. Under normal circumstances, the spring rod 19 is expanded to make the height of the sealing pad 17 higher than the height of the guide pipe 15 and the drainage pipe 15. The connection of the pipe 12 can prevent the exhaust gas from entering the interior of the wastewater collection box 14, and the water droplets are affected by the structure of the built-in air guide pipe 18 that is concave in the middle and are concentrated on the upper surface of the sealing gasket 17. The increased weight of the sealing gasket 17 will cause the spring rod 19 to be compressed. At this time, the water droplets can be transferred to the interior of the wastewater collection box 14. When more impurities are attached to the surface of the sealing gasket 17, the spring rod 19 cannot be restored and is continuously compressed. The pressure sensor 9 contacts the lower inner wall of the drain pipe 12 and is triggered. At this time, the alarm 16 receives the information sent by the pressure sensor 9 and starts to alarm to remind the staff.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
