Treatment system for waste gas containing volatile organic compounds

A treatment system for waste gas containing VOCs, the treatment system comprising a zeolite revolver (10), an incinerator (20) and a network of pipes, valves and filters;

• the zeolite revolver (10) having an absorption zone (11), a purge zone (12) and a desorption zone (13);
• the incinerator (20) connecting to the zeolite revolver (10) by the network of pipes and having a regenerative heat recovery bed (22) and a heat exchanger (21);
• and
• the network of the pipes comprising:
• a gas supply pipe (30) connecting to the absorption zone (11) of the zeolite revolver (10) to pipe untreated waste gas containing VOCs into the zeolite revolver (10), wherein at least one gas supply filter (40) are mounted on the gas supply pipe;
• a discharge pipe (31) connecting between the absorption zone (11) and a chimney and a gas supply fan (60) mounted in the discharge pipe (31);
• a purge supply pipe (32) connecting to the purge zone (12) of the zeolite revolver (10) to pipe untreated waste gas into the zeolite revolver (10) and at least one purge air filter (41) mounted in the purge supply pipe (32);
• a purge discharge pipe (33) connecting the purge zone (12) of the zeolite revolver (10) and the heat exchanger (21) in the incinerator (20);
• a heat exchanger discharge pipe (34) connecting the desorption zone (13) in the zeolite revolver (10) and the heat exchanger (21) in the incinerator (20);
• a hot gas pipe (35) connecting the desorption zone (13) to the incinerator (20) as an fuel inlet of the incinerator (20);
• a gas discharge pipe (36) connecting the incinerator (20) to draw out treated waste gas inside the incinerator (20);
• and
• a heat exchanger bypass pipe (37) connecting the purge discharge pipe (33) and the heat exchanger discharge pipe (34) and having a temperature regulating valve (53) mounted in the heat exchanger bypass pipe (37).
