Photocatalytic compound exhaust gas treatment system

Abstract

The invention relates to a photocatalytic compound exhaust gas treatment system. An exhaust gas collecting cover is connected with a spray tower, the rear part of the spray tower is connected with a photolysis oxidization catalysis device, and the rear part of the photolysis oxidization catalysis device is connected with an air inducing device; a first filter screen is arranged between the photolysis oxidization catalysis device and the spray tower to realize filtration, and a second filter screen is arranged between the photolysis oxidization catalysis device and the air inducing device to realize filtration; and a plurality of TiO2 filter screens and a plurality of UVC tubes and ozone generators are arranged in the photolysis oxidization catalysis device at intervals. A spraying technology is used to cool exhaust gas and remove one part of dusts in the exhaust gas, so primary purification and maintenance of cleanness of the UVC tubes are realized; a catalyst is arranged, so the photolysis oxidization efficiency is greatly improved under the catalysis of the catalyst; and high temperature exhaust gas or exhaust gas with complex components is cooled and washed, enters the photolysis oxidization device and undergoes secondary treatment, so disadvantages of single technologies are overcome.

Description

technical field [0001] The invention relates to a waste gas treatment system in environmental protection equipment, in particular to a photocatalytic composite waste gas treatment system. Background technique [0002] The country pays more and more attention to environmental protection. At present, the waste gas treatment technology on the market relies on UVC tubes to crack and oxidize the waste gas components. The effect will be greatly affected (UVC tube, the ideal temperature is within 75 degrees Celsius, if it exceeds this temperature, the ability to crack the molecular bonds of exhaust gas will be weakened, and the tube will be easily broken); single UVC photolysis technology, the composition The effect of complex waste gas treatment is not ideal, and the method of only increasing the power is a waste of energy, which conflicts with energy saving and consumption reduction. [0003] CN 201296683Y discloses a photodegradation device for waste gas and wastewater and its ...
