Jiangsu long Thai technology to explain the principle of adsorption recovery waste gas treatment pro
Adsorption recovery is mainly the adsorption of organic solvents in waste gas by adsorption material, and the method of removing and recovering organic solvent.
In the process of organic waste gas treatment, adsorption is one of the methods with good treatment effect and wide use. Adsorbent has activated carbon, diatomite, zeolite and so on, in which the use of activated carbon adsorption most. Through the adsorption system, not only can greatly reduce the VOCs concentration of the exhaust gas, achieved emission standard, but also through adsorption desorption, the collection can be used in production, material recycling, reduce material consumption.
Process principle
Adsorption: the waste gas containing VOCs passes through the adsorbent bed, and VOCs is absorbed in the microporous structure of the adsorbent, and the clean gas is discharged into the atmosphere.
Desorption: when the adsorbent is saturated and loses its adsorption performance, the adsorbent needs to be desorbed and regenerated. The main heat source is used for gasifying the adsorbate, and then carried out by the carrier.
Purging: in the process of heating and gasification, the adsorbent is also heated accordingly. Low temperature is beneficial to the adsorption process, so the temperature of adsorbent is needed to be reduced.
Liquid separation is the method of separating the mixture by boiling point difference between the two components in the mixture to recover the useful components satisfying the quality requirements. Long Tai environmental protection liquid separation equipment, relying on my company's powerful research team and technical support of the various colleges and universities, research institutes, in the industry has a wealth of project design and implementation experience.
Process principle
Distillation: the use of reflux technology to achieve high purity and high recovery of separation operations, known as rectification.
Scraper gas stripping: after rectification treatment, the light components in the mixed liquid are vaporized again and extracted with gas to obtain the recombinant substances satisfying the purity requirement.
Decolorization: after the treatment of the scraper after the reorganization of the decolorization process, to meet the requirements of the color of the recombinant substances.
Through the multistage separation treatment of mixed liquid, the single component satisfying the quality requirement can be obtained, and the material recycling can be realized, and the benefit maximization can be ensured.
Jiangsu Dragon Environmental Protection adsorption recovery waste gas technical characteristics:
