[0002] The high-temperature exhaust gas generated in the industrial production process has high thermal energy and contains various gaseous pollutants that will affect the air quality, including carbon dioxide, carbon disulfide, hydrogen sulfide, nitrogen oxides, carbon monoxide, lead and mercury sulfate, smoke, etc. Therefore, if these waste heat are directly discharged without treatment, it will not only cause a large amount of energy waste, but also pollute the environment.

[0003] At present, there are independent devices related to waste heat exchange or waste gas absorption. However, they cannot achieve energy recovery and purification of waste gas at the same time, and the treatment effect is poor.

The spray pipe passes through the top wall of the absorption treatment pipeline and is horizontally arranged on the top wall inside the absorption treatment pipeline. The liquid inlet valve is arranged at one end of the spray pipe located on the outer wall of the absorption treatment pipeline. The spray pipe is located in the absorption treatment pipeline and a plurality of sprayers are evenly arranged on the pipeline, and the sprayers are evenly distributed between a plurality of porous plates.

[0026] By setting the adsorption device in the heat exchange pipe 1, sufficient heat exchange between waste heat and water can be achieved while odor or impurities in the waste heat can be adsorbed and removed; by setting the porous plate 8 in the absorption treatment pipe 2, the speed of the exhaust gas passing through the spraying area can be effectively reduced, and it is beneficial to the uniform distribution of the exhaust gas during the spraying process, thereby ensuring the sufficient removal of exhaust gas pollutants; by the composite structure of the heat exchange pipe 1 and the absorption treatment pipe 2, heat exchange and absorption of high-temperature exhaust gas can be achieved in the same equipment, the equipment cost is greatly reduced, and the treatment efficiency is greatly improved.

[0027] In this embodiment, the adsorbent includes a heat exchange groove 3 and activated carbon 4. Support plates 16 are arranged at both ends of the heat exchange pipe 1. A plurality of heat exchange grooves 3 are horizontally opened on the support plate 16. Activated carbon 4 is arranged between the heat exchange grooves 3 on the support plate 16.

[0028] In this embodiment, the cold water assembly includes a cold water valve 10 and a cold water pipe 17. The cold water pipe 17 is connected to the top of the heat exchange pipe 1. The cold water valve 10 is arranged at one end of the cold water pipe 17 close to the heat exchange pipe 1. A water supply structure, such as a water pump or the like, is arranged at one end of the cold water pipe 17 away from the heat exchange pipe 1. This is a common structure and will not be described in detail here.

[0029] In this embodiment, the spraying part includes a sprayer 6, a spray pipe 18 and a liquid inlet valve 14. The spray pipe 18 passes through the top wall of the absorption treatment pipeline 2 and is horizontally arranged on the top wall inside the absorption treatment pipeline 2. The liquid inlet valve 14 is arranged at one end of the spray pipe 18 located on the outer wall of the absorption treatment pipeline 2. A plurality of sprayers 6 are evenly arranged on the spray pipe 18 located inside the absorption treatment pipeline 2. In order to achieve a better spraying effect and ensure sufficient removal of exhaust gas pollutants, the sprayers 6 are evenly distributed between a plurality of porous plates 8. A water supply structure, such as a water pump and other devices, is arranged at one end of the spray pipe 18 away from the absorption treatment pipeline 2. It is a common structure and will not be described in detail here.

[0030] The spray pipe 18 is arranged through a plurality of perforated plates 8 .

[0031] In this embodiment, the sewage tank 7 is surrounded by the bottom wall of the absorption and treatment pipeline 2 and two baffles 19 arranged at both ends of the absorption and treatment pipeline 2, and the porous plate 8 is located above the sewage tank 7.

[0032] In this embodiment, a steam release valve 11 and a pressure gauge 12 are also provided on the top of the heat exchange pipe 1. The pressure gauge 12 is used to monitor the pressure in the heat exchange pipe 1.

[0033] Working process: Open the cold water valve 10 to inject water into the heat exchange pipe 1, and evenly pass the production waste heat into each activated carbon 4 through the heat distribution cover 5. While adsorbing the odor pollutants in the exhaust gas, the heat is fully exchanged with the cold water in the heat exchange tank 3. After reaching the required temperature, steam or hot water is supplied. Subsequently, the exhaust gas reaches the absorption treatment pipe 2 through the heat exchange pipe 1, and is evenly dispersed through the multiple small holes of the porous plate 8. Due to the blocking effect of the porous plate 8, the exhaust gas passing rate is reduced, thereby ensuring sufficient spray absorption and no environmental pollution after discharge.
