Description
Technical field
The present invention relates to waste gas processing methods, and in particular to the organic waste gas treatment method based on photooxidation.
Background technology
With the continuous expansion of social progress and industrial technology, the weaving of textile and Compound Fabric, gold stamping cloth, moulding cloth
The production of equal buntings is more and more common, and the buntings such as Compound Fabric, gold stamping cloth, moulding cloth can make largely to have in process of production
The organic solvents such as solvent such as polyester, resin, glue, butanone, diluent, these are by the polyester of heating, resin, glue, fourth
The organic solvents such as ketone, diluent can become volatile organic waste gas, these organic exhaust gas directly empty, and will be caused to environment seriously
Pollution, is detrimental to health and ecological environment.For environmental protection, atmosphere pollution is avoided, the exhaust gas containing pernicious gas is discharged into greatly
Purified treatment must be carried out before gas, the pernicious gas amount or harmful gas concentration for being discharged into air must not exceed as defined in discharge standard
Numerical value, if high altitude discharge only solves the pollution problem in some areas, the nuisance total amount for being discharged into air is not reduced, not from
Fundamentally solve atmosphere polluting problem.Existing waste gas processing method such as photocatalysis organic waste gas treatment method, due to organic waste
Dust particle containing part in gas, if by the way that dust particles are remained in processor when photocatalysis organic waste gas treatment method
It is interior, to affect the normal work of light-catalyzed reaction, in addition, since exhaust gas has certain temperature, if directly being urged by light
Change handles exhaust gas, then can reduce the reaction efficiency and quality of exhaust gas.
Invention content
The waste gas reaction that the present invention solves waste gas processing method of the existing technology is inefficient, and poor quality's asks
Topic provides the organic waste gas treatment method based on photooxidation, and exhaust treatment efficiency and processing matter can be effectively improved when applying
Amount, while dust particles when exhaust-gas treatment being avoided to remain in the problems in processor.
The present invention is achieved through the following technical solutions：
