Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to an organic waste gas treatment device and a treatment method. Background Art

[0002] The hydrocarbons and nitrogen oxides in organic waste gas react with ultraviolet rays to generate ozone, which can lead to atmospheric photochemical smog events, endangering human health and plant growth. In addition, organic waste gas combines with other pollutants in the air and generates secondary organic particulate matter or secondary organic aerosols under the irradiation of sunlight. Most of them are fine particles that are not easy to settle and can remain in the atmosphere for a long time. They have a strong scattering ability for light and can significantly reduce atmospheric visibility. At the same time, they can directly enter and adhere to the upper and lower respiratory tracts and lung lobes of the human body, and be deposited in the upper and lower respiratory tracts and alveoli respectively, causing rhinitis, bronchitis and other respiratory diseases. Long-term exposure to this environment can also induce cancer.

[0003] In the treatment process of organic waste gas, the filter screen plays a key role and is responsible for effectively intercepting dust particles in the waste gas. However, after long-term use, these screens are prone to clogging due to dust accumulation, forcing frequent manual cleaning or even replacement, which significantly increases maintenance costs and operational complexity. Although the organic waste gas treatment devices currently on the market have introduced cleaning plate technology to achieve automatic cleaning of the filter screen surface, this mechanism often has difficulty reaching and removing dust particles embedded in the filter mesh. The continued accumulation of these residual dust will still cause the screen to clog, thereby weakening the efficiency and effectiveness of waste gas treatment.
