Abstract
Description
Technical Field
[0001] This utility model relates to the field of catalytic combustion technology, specifically a catalytic combustion device with waste gas purification function. Background Technology
[0002] With the rapid development of industry, the emission of organic waste gases generated in various industrial production processes is constantly increasing, causing serious environmental pollution. These organic waste gases are complex in composition and have a wide concentration range, making it difficult for traditional waste gas treatment methods to meet increasingly stringent environmental protection requirements. Catalytic combustion devices are widely used in industries such as paint, rubber processing, plastics processing, resin processing, leather processing, food processing, and foundrying. Catalytic combustion is a typical gas-solid phase catalytic reaction, essentially an oxidation process involving active oxygen. In the catalytic oxidation process, the catalyst lowers the activation energy, allowing the organic waste gas to undergo flameless oxidation at a lower ignition temperature, decomposing it into carbon dioxide and water while releasing a large amount of heat energy, thereby achieving the purpose of removing harmful substances from the waste gas.
[0003] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. Common catalytic combustion devices cannot effectively pre-treat waste gas during waste gas treatment, resulting in particulate matter or other pollutants being mixed in the waste gas, thus weakening the subsequent treatment effect; 2. Common catalytic combustion devices are not easy to disassemble after operation, the whole process is time-consuming and labor-intensive, and cleaning and maintenance are troublesome, which may lead to a reduction in the subsequent treatment effect.

The output shaft of the motor 506 runs vertically through the inside of the second gear 505.
[0025] The adsorption assembly 16 includes an adsorption tank 1601 installed inside the adsorption box 14, an activated carbon layer 1602 installed inside the adsorption tank 1601, a first cover plate 1603 fixedly connected to one end of the adsorption tank 1601, and a first handle 1604 fixedly connected to the center of one end of the first cover plate 1603.

[0027] In this embodiment, as Figure 1 As shown, the exhaust pipe 8 is located above the intake pipe 3. This design allows the collected exhaust gas to be discharged after being purified by spraying, avoiding the situation where the exhaust gas is discharged without being purified by spraying. This makes the adsorption and catalytic combustion processes more efficient and prevents particulate matter from damaging the device.
[0028] In this embodiment, as Figure 1 As shown, the third connecting gas pipe 22 is located above the desorption gas pipe 19; through this design, the pretreated gas can be discharged after catalytic combustion, which makes the catalytic combustion effect of the exhaust gas better and the discharged gas more in line with the ecological environment standards.
[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the motor 506 and the second gear 505 form a rotating structure, and the second gear 505 and the first gear 504 form a meshing transmission structure. Through this design, the exhaust gas can be effectively pretreated and sprayed for purification.

Grooves are provided on both sides of the top of the first fixing frame, and a first fixing rod with the same shape as the groove is fixedly connected to both sides of the bottom of the adsorption tank 1601. This design allows the staff to quickly disassemble the adsorption assembly 16, reducing the time cost required for disassembly and making the whole process time-saving and labor-saving. This improves the efficiency of the staff in maintaining and cleaning the assembly, so that the subsequent adsorption effect can be well maintained, thereby improving the efficiency and effect of waste gas treatment.

This design allows the staff to quickly disassemble the catalytic combustion component 21, reducing the time cost required for disassembly and improving the efficiency of maintenance and cleaning. This ensures that the subsequent catalytic combustion effect can be well maintained, thereby improving the efficiency and effect of exhaust gas treatment.
[0032] In this embodiment, as Figure 1 and Figure 4 As shown, a catalyst is placed on top of the heating plate 2101; this design effectively reduces the activation energy of the combustion reaction, allowing the reaction to be carried out at a lower temperature for flameless oxidation, and oxidizing and decomposing carbon dioxide and water, thereby achieving the purpose of removing harmful substances in the exhaust gas and increasing the efficiency and effect of catalytic combustion of exhaust gas.
[0033] The method of use and advantages of this utility model: The catalytic combustion device with exhaust gas purification function operates as follows:
[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, blower 4 is turned on, and the exhaust gas enters the purification tank 2 through the air inlet pipe 3. Water is injected into the water inlet pipe 501, and the water is sprayed out through the connecting pipe 502 and the spray head 503 to purify the exhaust gas. At the same time as the spray purification, motor 506 is turned on, causing the second gear 505 to rotate. The first gear 504, which meshes with the second gear 505, drives the water inlet pipe 501 to rotate, thereby causing the spray head 503 to rotate, so as to purify the exhaust gas better and more evenly. The water after spraying will enter the sludge collection tank 7 through the drain pipe 6 for subsequent treatment. Then, air pump 9 is turned on, and the purified gas will enter the air supply pipe 10 through the air outlet pipe 8. Adsorption fan 12 is turned on, and the gas will enter the adsorption tank 14. After being adsorbed by the activated carbon layer 1602, it will be converted into clean gas and enter the second connecting air pipe. 17. The gas is discharged through the exhaust pipe 23. When the activated carbon layer 1602 is fully adsorbed, the adsorption fan 12 is turned off and the desorption fan 18 is turned on. The gas will enter the catalytic combustion chamber 20 through the desorption gas pipe 19. At this time, the heating plate 2101 is heated. The gas will react with the catalyst on the heating plate 2101, thereby converting the waste gas into clean gas, which enters the third connecting gas pipe 22 and is discharged through the exhaust pipe 23. When the catalytic combustion work is over, the operator can pull the first handle 1604 to pull out the adsorption tank 1601 along with the activated carbon layer 1602 for cleaning. After cleaning, it can be put back. At the same time, the operator can pull the second handle 2103 to remove the heating plate 2101 along with the catalyst for cleaning and catalyst replacement. After cleaning and replacement, it can be put back.
