Abstract
A treatment system for waste gas containing VOCs is composed of a zeolite revolver ( ), an incinerator ( ) and a network of pipes, valves and filters. The zeolite revolver ( ) consists of an adsorption zone ( ), a purge zone ( ), and a desorption zone ( ) to remove VOCs from untreated waste gas in the adsorption zone ( ) and then separate the VOCs from the saturated zeolite in the desorption zone ( ). The zeolite is cooled down in the purge zone ( ) so it can be used again. The separated VOCs are piped into the incinerator ( ) to be used as fuel. Whereby, the treatment system for waste gas containing VOCs operates efficiently and economically.
