Description

[0002] Waste gas treatment refers to the process of purifying waste gas containing pollutants generated in industrial and other places, aiming to reduce its harm to the environment and human health. The regenerative thermal oxidizer (RTO), also known as the regenerative incinerator, is a VOC organic waste gas treatment equipment.

Through the mutual cooperation of the second filter component and the collecting component, the impurities in the exhaust gas to be treated can be filtered and collected, effectively preventing the impurities from affecting the efficiency of the thermal oxidation furnace body 1 in treating the exhaust gas.

[0066] The above embodiment discloses an exhaust gas treatment device with energy-saving function. It should be noted that the principle of desorption and regeneration of the activated carbon plate group 206 by hot nitrogen is to utilize the displacement effect and thermal effect of nitrogen to desorb organic matter adsorbed on the activated carbon plate group 206, thereby achieving regeneration of the activated carbon plate group 206.

[0067] When in use, the exhaust gas will be discharged into the inner cavity of the shell 6 through the second air inlet pipe 8. At this time, the second motor 301 is started to drive the filter cylinder 306 to rotate, and the two fans 5 are started at the same time to accelerate the flow of air in the thermal oxidation furnace body 1 and the inner cavity of the shell 6. At this time, the exhaust gas filtered by the filter cylinder 306 can be discharged into the inner cavity of the thermal oxidation furnace body 1 through the first air inlet pipe 4 and a fan 5, so that the exhaust gas can be processed. At the same time, the impurities on the outer wall of the filter cylinder 306 can be cleaned by the brush on the scraper plate 305. At this time, the cleaned impurities fall along the upper surface of a second sealing partition 10 through the discharge port 304 into the inner cavity of the collection box 303, so that the impurities can be collected for centralized processing of the impurities.

[0068] At the same time, the gas treated by the thermal oxidation furnace body 1 can be discharged into the inner cavity of the shell 6 through the outlet pipe 7 and another fan 5. At this time, the untreated residual waste gas in the treated gas is filtered by the activated carbon plate group 206, and then the filtered gas can be discharged into the inner cavity of the air guide groove 208 through the air supply pipe 207. At this time, the gas in the inner cavity of the air guide groove 208 can be discharged to the outside through an exhaust pipe, thereby realizing the treatment of the waste gas;

[0069] When the activated carbon plate group 206 needs to be desorbed, the first motor 201 is started to drive the first gear 203 to rotate. At the same time, the switching disk 205, driven by the first gear 203, drives the gas guide groove 208 to rotate along the inner wall of the support frame 202 until one end of the gas guide groove 208 moves to the end of the other exhaust pipe, thereby realizing convenient switching of the gas delivery direction;

[0070] During this process, the toothed plate 209 slides along the outer wall of the limiting rod 204 under the meshing drive of the first gear 203. At this time, the second gear 2010 drives the transmission rod 2011 to rotate under the meshing drive of the toothed plate 209. At the same time, the transmission rod 2011 drives the guide chute to rotate synchronously. At this time, the lifting slide 2013 slides and rises along the inner wall of the guide chute and the inner wall of the shell 6 through the guide slider 2012. At the same time, the blocking plate 2015 slides and rises along the inner wall of the fixed frame 11 through the lifting slide 2014 under the drive of the lifting slide 2013, thereby releasing the blockage of the port of the third air inlet pipe 12.

[0071] Afterwards, hot nitrogen can be transported to the inner cavity of the outer shell 6 through the third air inlet pipe 12 and the air inlet. At this time, the activated carbon plate group 206 can be desorbed and regenerated by the hot nitrogen. At the same time, the exhaust gas generated by the desorption and regeneration of the activated carbon plate group 206 is discharged to the side of the first sealing partition 9 away from the support frame 202 through the air supply pipe 207, the air guide groove 208 and another exhaust pipe. In this way, the exhaust gas generated by the desorption and regeneration can be filtered through the filter mesh tube 306, and then the above operation is repeated to perform secondary treatment on the untreated residual exhaust gas. When the activated carbon plate group 206 completes the desorption and regeneration, the first motor 201 is started to reset, so that the treated and filtered gas can continue to be discharged, thereby further improving the efficiency of exhaust gas treatment.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
