UV photodissociation depurator 14 is a kind of novel high-tech environmental protection equipment, the high energy high ozone UV ultraviolet beam that this product utilization is special irradiates foul gas (organic exhaust gas), change foul gas such as ammonia, trimethylamine, hydrogen sulfide, first sulfur hydrogen, methanthiol, methyl sulfide, methyl disulfide, Carbon bisulfide and styrene, sulfide, VOC class, the molecular chain structure of benzene,toluene,xylene, make organic or inorganic macromolecule malodorous compound strand, under high energy ultraviolet Line beam irradiates, degraded is transformed into low molecular compound, such as CO2、H2O etc..
Utilize high energy high ozone UV ultraviolet illumination to decompose the oxygen molecule in air and produce free oxygen, i.e. active oxygen, because the taken positron-electron of free oxygen is uneven so need to be combined with oxygen molecule, and then produce ozone.Owing to Pre-Ozonation on Organic Matter has extremely strong Oxidation, foul gas and other zest abnormal flavour there is the elimination effect got instant result.After foul gas utilizes exhaust equipment to be input to this cleaning equipment, cleaning equipment uses high energy UV ultraviolet beam and ozone that foul gas carries out collaborative decomposition oxidation reaction, makes its Degradation and Transformation of foul gas material become low molecular compound, water and carbon dioxide.
This utility model also provides for a kind of organic waste-gas purification method for shoemaking workshop, comprises the following steps:
Under the effect of centrifugal fan 15, collect, by gas skirt 11, the organic exhaust gas that baking box produces；
Organic exhaust gas enters low-temperature plasma processor 13 by gas sampling airduct and carries out electrolytic treatments, enters back into UV photodissociation depurator 14 and carries out photodissociation process；
Discharged by discharge duct 16.
This utility model provides a kind of cleaning equipment for waste organic gas for shoemaking workshop, and organic exhaust gas is mainly brush coating and baking operation generation, and its principal character pollutant are micelle particulate matter and benzene,toluene,xylene etc.；Adopting low temperature plasma+UV light solution, from the aspect analysis such as treatment effect and operating cost, this technique removal efficiency is high, and operating cost is relatively low, easy to operate, and comprehensive utilization is convenient.
