Description

Technical Field

[0001] This invention relates to the fields of chemical and environmental protection technology, and in particular to an organic waste gas treatment device. Background Technology

[0002] VOCs (volatile organic compounds) refer to organic compounds with a saturated vapor pressure greater than 133.32 Pa at room temperature and a boiling point between 50 and 260°C at normal pressure, or any volatile organic solid or liquid at normal temperature and pressure. Due to the high volatility of organic solvents, the vast majority will be converted into VOCs and emitted into the air.

[0003] Existing methods use exhaust gas purification towers to purify organic waste gas.

[0062] Once the first carbon layer A22a reaches the specified temperature, the second carbon layer A22b undergoes a heating and desorption process. The desorbed gas is released through the pressure relief valve 11, and then oxidized by the oxidation device 10. The oxidized gas is then reabsorbed by the activated carbon tank B3 through the pretreatment device 1 and discharged in compliance with standards. This process, by heating the carbon layers within the carbon tank separately, features a small installed capacity and relatively high thermal efficiency, offering advantages in energy saving and consumption reduction.
