Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and more specifically, to a catalytic combustion waste gas treatment device. Background Technology

[0002] Waste gas treatment refers to the pretreatment of waste gas generated in industrial sites and factory workshops before it is discharged to meet national standards for waste gas discharge. Generally, waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid and alkali waste gas treatment, odor waste gas treatment, and air sterilization, disinfection and purification. Catalytic combustion waste gas purification treatment devices require filtration to remove particulate matter before the waste gas enters. For example, patent CN216591754U discloses a catalytic combustion waste gas treatment device. The inlet pipe is located in the middle of the cleaning disc and the support disc. The recovered waste gas can be transported to the inside of the treatment device through the inlet pipe. Then the waste gas can continue to be transported downward through multiple circular grooves. Therefore, the waste gas will be gradually transported to the surface of the filter disc. Multiple filter holes can filter the particulate matter mixed in the waste gas. There will still be some dust in the waste gas. The waste gas can be catalytically incinerated inside the incineration hood. The incinerated waste gas continues to be transported to the inside of the treatment device for further filtration and treatment. At this time, the surface of multiple brush bristles is in contact with the surface of the filter disc, and the operator can start the motor.

[0003] When the above-mentioned device is working, the rotation of the support plate will also drive the cleaning plate and multiple brushes to rotate in the same direction. The surface of the multiple brushes will continuously rub against the particles clogging the filter holes, which can scrape the particles off. The particles will continue to be transported to the bottom of the treatment device body through the multiple filter holes. However, the rotation of the cleaning plate will also stir up the dust on the surface of the filter plate. The dust can also easily pass through the inside of the filter holes. The exhaust gas after filtration still contains some dust, which makes the waste treatment effect poor, and the discharged exhaust gas will also contain some impurity particles.

[0010] In a preferred embodiment, a flushing water distribution pipe is provided at the upper end of one side of the condensation filter box, and two circulating water inlet pipes and two circulating water outlet pipes are provided at the rear of the condensation filter box. The outer end face of each water inlet pipe is provided with multiple atomizing nozzles.

[0011] In a preferred embodiment, both the inlet pipe and the flushing branch pipe are connected to an external water supply device, and the lower end of the partition support plate is suspended. Both ends of the circulating condenser pipe are connected to the circulating water inlet pipe and the circulating water outlet pipe, and both the circulating water inlet pipe and the circulating water outlet pipe are connected to an external circulating water supply device.

This allows the high-temperature steam to evenly mix with the tiny particulate impurities remaining in the exhaust gas. Simultaneously, the condenser fins condense the water-containing steam, and the tiny particles in the exhaust gas, along with the water vapor, are adsorbed onto the surface of the condenser fins, thus further filtering the exhaust gas and improving the treatment effect of catalytic combustion exhaust gas. At the same time, the cleaning pipe and flushing nozzle can wash away the dust and impurities adsorbed on the surface of the condenser fins, making it easy to keep the condenser fins clean and preventing excessive dust accumulation from affecting the condensation effect of the condenser fins.

The condensation filter box 6 has multiple condensation fins 23 on both sides of the partition support plate 22. The end face of the condensation fins 23 is provided with a circulating condensation pipe 24.
