[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a skid-mounted catalytic oxidation device, such as... Figure 1 , Figure 2 and Figure 5 As shown, it includes a base structure 1, which includes a base 101 and a connecting column 102. An intake structure 2 is installed on the top of the base 101. One side of the intake structure 2 is connected to a buffer chamber 302 in the desorption mechanism 3. A gas return pipe 304 is installed inside the buffer chamber 302. A heating structure 4 is provided on the top of the buffer chamber 302. A catalytic structure 5 is installed on one side of the heating structure 4. The catalytic structure 5 is connected to an exhaust structure 6.

[0017] The base 101 has symmetrically fixed connecting columns 102 at its bottom. The connecting columns 102 have several groups of strip plates evenly distributed at intervals.

[0018] The air intake structure 2 includes an exhaust gas collection box 201. An air intake pipe 202 is fixedly provided inside the exhaust gas collection box 201. Filters 203 are fixedly installed on both the upper and lower sides of the air intake pipe 202, and their ends extend into the inner cavity of the buffer chamber 302. The air intake pipe 202 extends to one side of the buffer chamber 302 and communicates with the interior.

[0019] The buffer chamber 302 is a pipe, and an activated carbon adsorption chamber 301 is fixedly connected to the top of the buffer chamber 302. The activated carbon adsorption chamber 301 is provided in multiple sets and arranged in parallel. A thermal desorption pipe 303 is fixedly installed on the top of the activated carbon adsorption chamber 301. Each thermal desorption pipe 303 has a connecting pipe at the bottom that connects to the corresponding activated carbon adsorption chamber 301. A gas return pipe 304 is fixedly installed on the top of the buffer chamber 302. Each gas return pipe 304 has a connecting pipe at the top that communicates with the inside of the activated carbon adsorption chamber 301.

[0020] The device features an integrated design and skid-mounted structure, facilitating transportation and on-site installation, thus improving the efficiency of overall maintenance and ease of installation. During operation, industrial waste gas is collected through the waste gas collection box 201 and the intake pipe 202. Filters 203 on both sides of the pipe remove particulate matter and impurities. The filtered waste gas then enters the buffer chamber 302 through the pipe and is placed in the activated carbon adsorption chamber 301. Multiple sets of parallel activated carbon adsorption chambers 301 adsorb and purify the volatile organic compounds in the waste gas. The qualified gas is discharged through the exhaust stack 602. When the activated carbon is saturated, the heating chamber 401 is activated, heating air and sending it into the activated carbon adsorption chamber 301 through the thermal desorption pipe 303. The high-temperature desorption of the adsorbed organic matter and the high-concentration desorbed waste gas are drawn by the centrifugal fan 403 to the catalytic oxidation unit. The gas return pipe 304 circulates some of the hot air back to the activated carbon chamber, improving thermal utilization efficiency and reducing energy consumption.

[0021] Furthermore, in order to improve the environmental friendliness of the equipment, such as Figure 3 and Figure 4 As shown, the heating structure 4 includes a heating chamber 401, a heater is fixedly installed on the outer wall of the heating chamber 401, one side of the heating chamber 401 is adapted and fixedly connected to the catalytic reaction chamber 402, a centrifugal fan 403 is built into one end of the catalytic reaction chamber 402, one end of the centrifugal fan 403 is electrically connected to an external motor 404, and a bracket 405 is fixedly connected to the bottom of the motor 404.

[0022] The catalytic structure 5 includes a catalytic chamber 501, one side of which is connected to the interior of the thermal desorption pipe 303. A PLC controller 502 is installed on the top of the catalytic chamber 501. A gas return pipe 304 is provided on the outer wall of the catalytic chamber 501, and a one-way valve is provided on one side of the gas return pipe 304.

[0023] The exhaust structure 6 includes a mounting base 601 and an exhaust pipe 602. The exhaust pipe 602 is fixedly installed on the top of the mounting base 601, and the inner cavity of the exhaust pipe 602 is connected to one end of the thermal desorption pipe 303.

[0024] In operation, the device heats the desorbed waste gas to the catalytic reaction temperature via the heating chamber 401, and then it enters the catalytic reaction chamber 402. Under the action of the catalyst, the organic matter is oxidized and decomposed into carbon dioxide and water vapor, achieving harmless treatment. The PLC controller 502 monitors parameters such as temperature and flow rate in real time, and adjusts the operation of the heater and fan to ensure reaction efficiency. The treated clean gas is discharged through the exhaust stack 602. A one-way valve prevents gas backflow, and the centrifugal fan 403 ensures directional airflow. By setting up a return hot desorption pipe 303 and a gas return pipe 304, the purification work becomes more energy-efficient and reduces energy consumption, thereby improving the efficiency of catalytic oxidation treatment.

[0025] Working Principle: The device integrates components onto the base structure 1, facilitating efficient and convenient installation and portability. Organic waste gas generated during industrial production is collected via a pipeline system through the waste gas collection box 201. A double-layer filter 203 in the inlet pipe 202 performs preliminary filtration of the waste gas, removing dust, particulate matter, and other impurities. The waste gas then enters the buffer chamber 302, and subsequently the activated carbon adsorption chamber 301. The PLC controller 502 monitors the outlet concentration or sets a time period, automatically switching to desorption mode. The heating chamber 401... Upon startup, high-temperature hot air is generated and reverse-flowed into the saturated activated carbon adsorption chamber 301 through the thermal desorption pipe 303. The high temperature causes the adsorbed volatile organic compounds to desorb, forming high-concentration organic waste gas. The desorbed high-concentration waste gas is drawn into the catalytic reaction chamber 402 by the centrifugal fan 403. The gas return pipe 304 recycles part of the hot air to reduce energy consumption. The high-concentration waste gas is further heated to the catalytic reaction temperature in the heating chamber 401. The waste gas enters the catalytic chamber 501 and decomposes into carbon dioxide and water vapor under the action of the catalyst. The clean gas after catalytic oxidation is discharged through the exhaust pipe 602.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
