The invention relates to the technical field of
waste gas processing, and specifically relates to a
waste gas processing device and a
waste gas processing method. The waste gas processing device comprises an absorbing
tower, a gas-liquid mixing device, a delivering device, a UV oxidizing device, and a releasing device which is connected to the UV oxidizing device. The absorbing
tower is provided with a liquid containing part, a gas inlet, a filling material layer, a final
nozzle, and a
demister from bottom to top in sequence. The final
nozzle is communicated with the liquid outlet of the delivering device, the liquid inlet of the gas-liquid mixing device is communicated with the liquid containing part, the liquid outlet of the gas-liquid mixing device is communicated with the UV oxidizing device, and the gas outlet of the UV oxidizing device is communicated with the liquid containing part. The waste gas processing method utilizes the provided waste gas processing device. According to the processing method, the adsorption,
catalytic oxidation, and spraying are effectively integrated together to strengthen the waste gas processing effect, moreover, different absorbing liquids that can effectively absorb the waste gas is provided according to the waste gas generated by different types of factories; the
waste processing method is flexible and has a wide application range, furthermore, the purification efficiency is improved, the operation is simple and convenient, and the
investment cost and operation cost are low.
