Abstract
A treatment system for waste gas containing VOCs is composed of a zeolite revolver (10), an incinerator (20) and a network of pipes, valves and filters. The zeolite revolver (10) consists of an adsorption zone (11), a purge zone (12), and a desorption zone (13) to remove VOCs from untreated waste gas in the adsorption zone (11) and then separate the VOCs from the saturated zeolite in the desorption zone (13). The zeolite is cooled down in the purge zone (12) so it can be used again. The separated VOCs are piped into the incinerator (20) to be used as fuel. Whereby, the treatment system for waste gas containing VOCs operates efficiently and economically.
