Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas purification, and more specifically to an organic waste gas catalytic combustion purification device. Background Art

[0002] Organic waste gas refers to toxic and harmful gases produced in the production process of factories, steel mills, etc. This gas has a strong odor and seriously pollutes the environment while causing great harm to people's health. In order to avoid the harm caused by organic waste gas, it is necessary to use an organic waste gas catalytic combustion and purification integrated device to purify the organic waste gas.

[0003] The existing catalytic combustion purification device for organic waste gas still has the following problems: when the existing catalytic combustion purification device for organic waste gas is in use, the dust generated during the catalytic combustion of the organic waste gas is usually adsorbed on the activated carbon plate, resulting in poor long-term saturation filtration effect of the activated carbon plate, and it is difficult to clean the dust on the activated carbon plate in the existing catalytic combustion purification device for organic waste gas, and most of them are cleaned after disassembly, which not only has poor cleaning efficiency, but also has unsatisfactory cleaning effect, which brings many inconveniences to actual use;

[0004] Moreover, when the existing catalytic combustion purification device for organic waste gas is in use, a large amount of heat will be generated during the catalytic reaction, which makes the temperature of the purified waste gas relatively high. If it is not cooled down, it may cause certain harm to the environment. The purification effect itself is also poor. The air purified by catalytic combustion alone may still have a small amount of organic matter remaining, which will still cause environmental pollution if it is discharged directly.

[0005] In view of this, we propose a catalytic combustion purification device for organic waste gas. Utility Model Content
