Volatile organic compound treatment device

The utility model discloses a volatile organic compound (VOC) treatment device, which comprises at least two adsorption/desorption towers, a waste gas supply pipeline, an adsorbed gas exhaust pipeline and a catalyst oxidation treatment unit, wherein the waste gas supply pipeline is alternately communicated with the adsorption/desorption towers, so that the adsorption/desorption towers operate to adsorb; the catalyst oxidation treatment unit is alternately communicated with the adsorption/desorption towers, so that the adsorption/desorption towers operate to desorb; the catalyst oxidation treatment unit comprises a heat exchanger, a catalyst reactor, a gas inlet unit and a gas exhaust unit. According to the VOC treatment device, the adsorption/desorption towers and the catalyst oxidation treatment unit are matched with each other, so that VOC in the waste gas can be effectively removed; and the VOC treatment device has the advantage of relatively low cost and operation and maintenance convenience.
