Abstract
The utility model discloses a catalytic combustion photo-catalyst waste gas treatment device which comprises a catalytic combustion purification tower and a photo-catalyst purification tower. The catalytic combustion purification tower is composed of an adsorption system and a catalyst chamber, wherein the adsorption system is formed by a plurality of activated carbon adsorption beds. A heater and a combustion bed provided with metal catalysts are arranged in the catalyst chamber. Organic waste gas of a waste gas source enters the catalyst combustion purification tower is treated by the adsorption system and then enters the photo-catalyst purification tower to be treated, and therefore clean gas is obtained and is exhausted through a fan. When a certain activated carbon adsorption bed of the adsorption system reaches adsorption saturation to perform desorption, adsorption stops, a corresponding desorption valve is opened, the heater in the catalyst chamber is started, hot air generated in the catalyst chamber is sent to the adsorption beds, activated carbon desorbs high-concentration organic gas after being heated, the organic gas is led into the catalyst combustion bed through a desorption fan, and under the action of the metal catalysts, flameless catalyst combustion is performed.
