[0001] The utility model relates to the technical field of waste gas treatment, in particular to an environmentally friendly recycling box for waste gas treatment. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within enterprise factories. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have a cumulative effect, which will cause more serious harm to human health.

[0003] Most exhaust gas treatment devices do not have the function of recovering the waste heat from combustion exhaust gas. The waste heat in the combustion exhaust gas can generally be recycled and utilized. If the waste heat in the exhaust gas cannot be recovered well, the waste heat in the exhaust gas may be wasted.

[0012] By adopting the above technical solution, the second water pump is turned on by connecting an external power supply, and then when the water pump is turned on, it will drive the circulation pipe to pump water. Then, because the water outlet end of the circulation pipe extends into the water storage tank, the water pumped out from the treatment tower by the circulation pipe will be sent into the water storage tank, so as to recycle the liquid used to remove particulate impurities in the exhaust gas to save costs.

[0027] Working principle: The exhaust gas from combustion enters the cavity 4 provided inside the treatment box 2 through the air inlet 3 opened at the front end of the treatment box 2, and then the heat carried by the exhaust gas from combustion exchanges heat with the heat inside the heat exchange tube 6. Then, with the cooperation of the heat exchange outlet tube 7 and the heat exchange inlet tube 8, the liquid inside the heat exchange tube 6 flows, which can continuously exchange heat with the exhaust gas introduced into the heat exchange tube 6, so as to recycle the waste heat generated in the exhaust gas from combustion, thereby utilizing the residual heat in the exhaust gas, and heating hot water or heat transfer oil, etc. through the waste heat recovery mechanism. , it is convenient to absorb and convert heat energy, which can be used in other places, ensuring the reuse of exhaust gas, avoiding waste of heat energy, and being more environmentally friendly. Then, when the exhaust gas passes through the cavity 4, because there is a filter screen 9 arranged in the cavity 4, some large particles of impurities in the waste can be better removed, and then the four supporting legs 11 installed at the bottom of the treatment tower 12 can better support the treatment tower 12. Then, because the outlet end of the connecting pipe 10 extends into the treatment tower 12, the exhaust gas can be subsequently treated in the treatment tower 12.

After the waste gas enters the treatment tower 12 through the connecting pipe 10, the first water pump 17 is turned on by connecting the external power supply. The first water pump 17 will pump water from the water tank 15 through the water supply pipe 18, and then the liquid will be sent to the atomizing nozzle 19 through the water supply pipe 18. Then, when the waste gas in the atomizing nozzle 19 is sprayed, the water in the atomizing nozzle 19 will be discharged. The liquid for removing particulate impurities from the exhaust gas will remove some particulate impurities in the exhaust gas after it comes into contact with the exhaust gas, thereby treating the exhaust gas. After the exhaust gas treatment is completed, it will be discharged from the exhaust port 14 on the top cover 13 through the activated carbon adsorption layer. After the exhaust gas passes through the activated carbon adsorption layer 24, the odor in the exhaust gas will be removed. Then, because the activated carbon adsorption layer 24 is set on the limiting plate 23, the top cover 13 can be removed to facilitate the subsequent removal of the activated carbon adsorption layer 24 for replacement and cleaning.

[0031] Example 3:

[0032] Please refer to Figure 1-4 , an environmentally friendly recycling box for waste gas treatment, a leakage net 20 is set near the bottom of the inside of the treatment tower 12, a second water pump 21 is fixedly installed on the upper surface of the bottom plate 1 just below the treatment tower 12, and a circulation pipe 22 is set in the second water pump 21, the water pumping end of the circulation pipe 22 extends into the treatment tower 12, and the water delivery end of the circulation pipe 22 extends into the water storage tank 15.

[0033] Working principle: After the liquid in the water tank 15 used to remove particulate impurities in the exhaust gas removes the particles in the exhaust gas, it will be filtered by the filter net 20 set in the treatment tower 12, and then the liquid will enter the bottom of the treatment tower 12, and then the second water pump 21 will be turned on by connecting to an external power supply. When the water pump is turned on, it will drive the circulation pipe 22 to pump water. Then, because the water outlet end of the circulation pipe 22 extends into the water tank 15, the water pumped out from the treatment tower 12 by the circulation pipe 22 will be sent into the water tank 15, so as to recycle the liquid used to remove particulate impurities in the exhaust gas to save costs.
