Abstract

The invention discloses a method and a device for separate oxidation and cyclone purification of organic waste gas. The device comprises a cyclone purifying tower and a catalytic absorbent recycling system arranged at the bottom of the cyclone purifying tower, wherein a catalytic absorbent cyclone atomizing layer, an ultraviolet separate oxidation layer and an absorbed waste gas demisting layer are sequentially arranged in the cyclone purifying tower from bottom to top; the catalytic absorbent recycling system is used for providing a nano-titania atomization liquid required for atomization for the catalytic absorbent cyclone atomizing layer and recycling the nano-titania slurry falling to the catalytic absorbent recycling system under the action of gravity. Cyclone atomizers are adopted for atomizing the nano-titania slurry, the contact area of the nano-titania slurry and organic waste gas is increased, and the catalytic efficiency is improved; the cyclone atomizers are arranged in a tangent circle manner, so that the nano-titania slurry spirally rises along the tangent circle, the disturbing degree of the organic waste gas and a catalyst is improved, and the reaction rate is increased.

Description

technical field [0001] The invention relates to the purification of organic waste gas, in particular to a method and device for purifying organic waste gas by zonal oxidation swirling flow. Background technique [0002] With the rapid development of my country's economy, the problem of organic waste gas pollution has become increasingly serious in recent years. The number of haze days in many areas has continued to increase, seriously affecting people's normal life and health. More and more scholars have begun to conduct research on the treatment of organic waste gas pollution, and have also developed many effective treatment methods. Research on organic waste gas pollution control technology can, on the one hand, create a good living environment for the society and improve people's quality of life; on the other hand, it can provide enterprises with environmental protection measures and improve the ability of sustainable industrial development. [0003] Organic waste gas ma...
