Abstract
The invention discloses a device for purifying organic waste gas by using ultrasonic waves and ultraviolet light cooperatively and a treatment method. The device is composed of an ultrasonic wave humidification system and an oxidation reaction system. The ultrasonic wave humidification system is composed of a draught fan, an ultrasonic wave generator and a humidification tank, a waste gas inlet and a waste gas outlet are formed in the side face of the humidification tank, and an oxidant liquid inlet is formed in the top of the humidification tank. The oxidation reaction system is a box, ultraviolet lamps and catalyst nets are arranged in the box, the catalyst nets are hollowed meshes coated with a catalyst, the catalyst nets are located between a gas outlet and the ultraviolet lamps in a blocking mode, the ultraviolet lamps are connected with a power supply through ballasts, and a gas inlet and the gas outlet are formed in the side face of the box. The ultrasonic wave generator is arranged at the bottom of the humidification tank. The waste gas inlet is communicated with the draught fan, and the waste gas outlet is communicated with the gas inlet of the oxidation reaction system. The device improves the oxidation efficiency greatly and has the advantages of being simple in structure, low in energy consumption and the like.
Description
[0001] (1) Technical field [0002] The invention relates to a waste gas treatment device and a treatment method, in particular to a device and a treatment method for purifying organic waste gas with ultrasonic and ultraviolet light, which can remove various volatile gaseous pollutants such as formaldehyde, toluene, ethylbenzene, xylene, etc. It is suitable for dealing with low-concentration industrial VOCs and indoor air pollution. [0003] (2) Background technology [0004] In recent years, the advanced oxidation method induced by ultraviolet light has been widely used in environmental protection fields such as sewage treatment, waste gas treatment and so on. The photocatalytic oxidation of VOCs has become a research hotspot in this field. The principle is that through various oxidants or catalysts such as H 2 o 2 , Fenton's reagent, ozone, TiO 2 After absorbing ultraviolet light, HO is generated to initiate a series of free radical reactions to degrade pollutants.
