The invention relates to the technical field of
waste gas treatment, and particularly discloses a comprehensive VOCs
treatment system for improving a workshop operation environment, the comprehensive VOCs
treatment system comprises a gas collecting hood, the top of the gas collecting hood is communicated with a gas inlet
pipe, and the gas inlet
pipe is sequentially provided with a spraying tank, a purification
tower and a negative pressure device in the gas flow direction; the spraying tank is communicated with a treating fluid
storage tank, and a mixing structure is arranged in the spraying tank; the interior of the purification
tower is sequentially divided into a treatment liquid
catalysis area, a spraying area and a filtering area from bottom to top; a gas distribution
assembly is arranged in the treatment liquid
catalysis area; a spraying
assembly is arranged in the spraying area, and the spraying
assembly is communicated with the treating fluid
storage tank; a filtering assembly is arranged in the filtering area; the bottom of the purification
tower is fixedly communicated with an overflow
pipe; a valve is mounted on the overflow pipe; and the top of the purification tower is communicated with the gas inlet end of the negative pressure device. Through multiple contact processes of the
waste gas and the treatment liquid, full contact of the treatment liquid and VOCs in the
waste gas is ensured, and the
treatment effect is ensured.
