Description

Technical Field

[0001] The utility model relates to the field of VOCs waste gas treatment, in particular to an adsorption treatment device for VOCs waste gas. Background Art

[0002] VOCs, volatile organic compounds, refer to organic compounds with a saturated vapor pressure greater than 70.91 Pa at room temperature, a boiling point below 50-260°C at a standard atmospheric pressure of 101.3 kPa, and an initial distillation point equal to 250 degrees Celsius, or any organic solid or liquid that can evaporate at room temperature and pressure.

[0003] When treating VOCs waste gas, activated carbon structures are mostly used to adsorb and filter harmful substances in the waste gas. When the waste gas is adsorbed and filtered by the activated carbon structure, a higher-power suction equipment is generally used to draw the waste gas in the air into the device for waste gas treatment. In order to prevent impurities or some floating matter in the air from being drawn into the device and affecting the waste gas treatment, a filter plate structure is generally installed at the air inlet end of the suction equipment. After long-term use of the waste gas treatment device, the installed filter plate structure is easily blocked by impurities such as floating matter or dust, which can easily lead to a decrease in the efficiency of the device in treating waste gas.
