[0002] Volatile organic compounds are a class of organic compounds that easily evaporate into gas at room temperature. They can come from a variety of sources, including industrial production, automobile emissions, solvent use, paints and coatings, printing processes, chemical production, etc. Organic waste gas has potential hazards to both the environment and human health. In terms of the environment, organic waste gas may cause ozone layer depletion, photochemical pollution and the generation of fine particulate matter, and have a negative impact on air quality. In terms of human health, long-term exposure to high concentrations of organic waste gas may lead to a series of health problems. Therefore, reducing the emission and control of organic waste gas is crucial to protecting the environment and human health.
[0003] In the existing process of treating organic waste gas by adsorption of activated carbon fibers, generally when the activated carbon adsorption is close to saturation, new activated carbon must be replaced. The replaced saturated activated carbon needs to be regenerated off-site, i.e., desorbed, for reuse. The off-site regeneration of activated carbon is troublesome, the loss of activated carbon fibers is serious and it is easy to cause secondary pollution.
[0004] Therefore, a complete set of equipment for adsorption, regeneration and catalytic combustion of organic waste gas is needed to solve the problem in the prior art that off-site regeneration of activated carbon is time-consuming, labor-intensive and prone to secondary pollution.

[0013] Compared with the prior art, the organic waste gas adsorption regeneration catalytic combustion complete set provided by the utility model has at least the following beneficial effects:
[0014] (1) By setting up a steam box, a catalytic combustion furnace and two activated carbon adsorption towers, when one activated carbon adsorption tower reaches saturation, the other activated carbon adsorption tower is activated to perform adsorption work. At this time, the saturated activated carbon adsorption tower is desorbed. The steam box introduces steam into the saturated activated carbon adsorption tower for desorption. The waste gas generated by desorption enters the catalytic combustion furnace through a vacuum pump for combustion purification and then is discharged. After the other activated carbon adsorption tower is saturated, the activated carbon adsorption tower that has completed desorption is activated again. The two activated carbon adsorption towers are operated alternately in this way, which can achieve continuous operation, improve production efficiency and ensure system stability. At the same time, the alternating operation can optimize the energy utilization of the system, reduce energy consumption and waste gas emissions, meet the requirements of sustainable development, and reduce production costs.
[0015] (2) By setting up a primary filtration mechanism, large particles of impurities in the exhaust gas are removed to protect the activated carbon adsorption tower. At the same time, a drying fan is set. After the desorption is completed, the steam temperature is reduced. In order to prevent the condensation of moisture due to the temperature drop during desorption from affecting the normal adsorption of the activated carbon, the drying fan is turned on to blow out the moisture to ensure that the activated carbon can perform the adsorption operation after the desorption operation is completed.

DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with embodiments.
[0022] See also Figure 1-4 The utility model provides a complete set of organic waste gas adsorption regeneration catalytic combustion device, including an air intake pipe 1, a steam box 10 and a drying fan 17. A primary filter mechanism 2 is arranged on one side of the air intake pipe 1, a first air supply pipe 3 is fixedly connected to one side of the primary filter mechanism 2, two activated carbon adsorption towers 4 are fixedly connected to the top of the first air supply pipe 3, and the two activated carbon adsorption towers 4 are both installed with an air intake valve 5 near the bottom, and the two activated carbon adsorption towers 4 are both installed with an exhaust valve 6 near the top, and the tops of the two activated carbon adsorption towers 4 are fixedly connected with a second air supply pipe 7. A catalytic combustion furnace 8 is fixedly connected to one side of the second gas transmission pipe 7, a discharge pipe 9 is fixedly connected to one side of the catalytic combustion furnace 8, a steam pipe 11 is fixedly connected to one side of the steam box 10, a water collecting pipe 12 is fixedly connected to the bottom of the two activated carbon adsorption towers 4, a spiral plate heat exchanger 13 is installed on the surface of the water collecting pipe 12, a water tank 14 is fixedly connected to the end of the water collecting pipe 12, a condenser 15 is fixedly connected to the top of the two activated carbon adsorption towers 4, a shell and tube condenser 16 is installed on the surface of the condenser 15, and an air duct 18 is fixedly connected to the top of the drying fan 17.
[0023] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth mentioning that pressure monitors are installed on the top of the two activated carbon adsorption towers 4. The pressure monitors can monitor the pressure changes inside the activated carbon adsorption tower 4 in real time, so as to help the operator understand the operation of the adsorption process. By monitoring the pressure changes, it is possible to promptly discover whether the activated carbon adsorption tower 4 is in a saturated state or whether desorption is completed. At the same time, by monitoring the pressure changes, equipment inspections and maintenance can be carried out regularly, and the accumulation inside the adsorption tower can be cleaned up in time to ensure the normal operation of the equipment.
[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that an air pump is installed between the second gas pipe 7 and the catalytic combustion furnace 8. The air pump can increase the pressure of the gas to ensure that the exhaust gas can flow smoothly from the second gas pipe 7 to the catalytic combustion furnace 8 and be discharged after combustion and purification in the catalytic combustion furnace 8.
[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the air duct 18 is connected to the bottom of the two activated carbon adsorption towers 4 to ensure that the drying fan 17 can blow out the moisture inside the activated carbon adsorption tower 4 and ensure that the activated carbon can perform the adsorption operation after the desorption operation is completed.
[0026] According to the above working process, it can be known that: by setting up the steam box 10, the catalytic combustion furnace 8 and the two activated carbon adsorption towers 4 in coordination, when the adsorption of one activated carbon adsorption tower 4 reaches saturation, the other activated carbon adsorption tower 4 is activated to perform adsorption work, and the saturated activated carbon adsorption tower 4 is desorbed at this time, and the steam box 10 introduces steam into the saturated activated carbon adsorption tower 4 for desorption, and the exhaust gas generated by desorption enters the catalytic combustion furnace 8 through the vacuum pump for combustion purification and then is discharged, and when the other activated carbon adsorption tower 4 is saturated, the activated carbon adsorption tower 4 that has completed desorption is activated again, and the two activated carbon adsorption towers 4 are alternately performed in this way.
[0027] Further as Figure 4 As shown, it is worth explaining in detail that the primary filter mechanism 2 includes a primary filter box 201 fixedly connected to one side of the intake pipe 1, a filter plate 202 is slidably connected to the top of the primary filter box 201, a handle 203 is fixedly connected to the top of the filter plate 202, and two fixing bolts 204 are rotatably connected to the top of the filter plate 202. By setting the primary filter mechanism 2, large particles of impurities in the exhaust gas are removed, and the activated carbon adsorption tower 4 is protected.
[0028] Further as Figure 4As shown, it is worth explaining in detail that a limiting slide groove corresponding to the filter plate 202 is opened on the inner wall of the primary filter box 201, which plays a limiting role in putting in and taking out the filter plate 202, thereby facilitating the replacement of the filter plate 202.
[0029] Further as Figure 4 As shown, it is worth explaining in detail that a mounting hole corresponding to the fixing bolt 204 is opened on the top of the primary filter box 201, and the mounting hole and the fixing bolt 204 cooperate to realize the detachable connection of the filter plate 202, while ensuring the filtering effect of the filter plate 202.
[0030] This scheme has the following working process: in actual use, the organic waste gas enters the interior of the primary filter box 201 from the intake pipe 2, the filter plate 202 removes large particle impurities in the waste gas, and the waste gas after the primary filtration enters the activated carbon adsorption tower 4 and is adsorbed and purified by the activated carbon before being discharged. The two activated carbon adsorption towers 4 are used alternately. When the adsorption of one activated carbon adsorption tower 4 reaches saturation, the other activated carbon adsorption tower 4 is activated for adsorption. At this time, the saturated activated carbon adsorption tower 4 is desorbed, and the steam box 10 passes steam into the saturated activated carbon adsorption tower 4 for desorption. The exhaust gas generated by desorption enters the catalytic combustion furnace 8 through the vacuum pump for combustion purification and then is discharged. After the other activated carbon adsorption tower 4 is saturated, the activated carbon adsorption tower 4 that has completed desorption is activated again. The two activated carbon adsorption towers 4 are alternately operated in this way. The steam condensate generated inside the activated carbon adsorption tower 4 flows into the water tank 14 for collection. After desorption is completed, the steam temperature decreases. In order to avoid the condensed moisture due to the temperature drop during desorption affecting the normal adsorption of activated carbon, the drying fan 17 is turned on to blow out the moisture to ensure that the activated carbon can perform adsorption after the desorption operation is completed.
[0031] In summary: by setting up a steam box 10, a catalytic combustion furnace 8 and two activated carbon adsorption towers 4, when the adsorption of one activated carbon adsorption tower 4 reaches saturation, the other activated carbon adsorption tower 4 is activated to perform adsorption work. At this time, the saturated activated carbon adsorption tower 4 is desorbed, and the steam box 10 introduces steam into the saturated activated carbon adsorption tower 4 for desorption. The exhaust gas generated by desorption enters the catalytic combustion furnace 8 through a vacuum pump for combustion purification and then is discharged. After the other activated carbon adsorption tower 4 is saturated, the activated carbon adsorption tower 4 that has completed desorption is activated again, and the two activated carbon adsorption towers 4 are alternately performed in this way; by setting up a primary filtration mechanism 2, large particles of impurities in the exhaust gas are removed, thereby protecting the activated carbon adsorption tower 4.
