Description

Technical Field

[0001] The utility model relates to the technical field of organic waste gas treatment, in particular to a device for oxidatively decomposing organic waste gas. Background Art

[0002] A large amount of organic waste gas will be generated during the industrial production process. The direct discharge of organic waste gas will cause pollution to the environment. It is necessary to decompose and treat the organic waste gas through waste gas treatment equipment to oxidize the harmful substances in the organic waste gas into harmless substances, thereby purifying the waste gas.

[0003] The prior art discloses a biological treatment device for organic waste gas (Announcement No.: CN214809757U), which includes a treatment box and an oxidation reaction tower. Partition 1 and partition 2 are arranged in the treatment box. Partition 1 and partition 2 divide the inner part of the treatment box into a dust removal area, a trickling filter area and a decomposition area. The dust removal area is connected with the decomposition area through the trickling filter area. A dust removal layer is arranged in the dust removal area. The dust particles and some organic matter in the waste gas are absorbed by the dust removal layer to achieve the purpose of dust removal, prevent the particles from clogging the subsequent biological filler layer and the decomposition layer, thereby reducing the treatment load of the biological filler layer and the decomposition layer.

[0004] However, the above technical solution and the prior art still have the following defects: the device achieves the dust removal function by setting a dust removal layer inside the dust removal area to filter and absorb the dust particles in the exhaust gas. However, when the dust removal layer absorbs too many dust particles, it will affect the subsequent filtration and gas circulation effects. Therefore, the dust removal layer needs to be regularly cleaned to ensure the dust removal and gas circulation effects. Utility Model Content

[0036] Embodiment three:

[0037] On the basis of the second embodiment, the difference from the second embodiment is that:

[0038] A reflux pipe 14 is provided on one side of the discharge pipe 11. The reflux pipe 14 is provided on the upper part of the flow limiting disk 122, and the reflux pipe 14 is connected and fixed to the other side of the liquid storage tank 131.

[0040] Working principle: first, the organic waste gas enters the exhaust gas filter cartridge 1 through the air inlet pipe 5 for dust filtration. The dust particles in the organic waste gas are filtered through multiple cylindrical filter screens 8. The organic waste gas passing through the filter assembly is then transported to the interior of the oxidation decomposition device 2 through the first docking port 3. The organic waste gas is oxidized and decomposed by the oxidation decomposition device 2 and then discharged. When it is necessary to remove the dust particles accumulated on the cylindrical filter screen 8 to ensure the filtering effect, the dust particles on the cylindrical filter screen 8 are sprayed and removed through the cleaning mechanism, and the fallen dust particles automatically fall into the conical cylinder 10 and the discharge pipe 11. The adjustment mechanism 12 is opened to allow the dust particles to automatically fall and be discharged. After the discharge is completed, the flow limiting disk 122 is reset and the servo pump 132 is driven to flush and clean the dust particles on the inner wall of the conical cylinder 10 through the nozzle 136. The cleaning liquid after cleaning flows back to the liquid storage tank 131 along the discharge pipe 11 and the reflux pipe 14 for recycling.
