Description
Technical Field
The invention relates to the field of waste gas treatment, in particular to a UV photolysis oxidation device.
Background
The UV photodissociation oxidation device irradiates waste gas with special UV light beam to crack malodorous gas. The special UV excitation light source is used for generating light quanta with different energies, the ozone substance is utilized to strongly absorb the light quanta, molecules of the ozone substance are dissociated and excited under the bombardment of a large number of energy-carrying light quanta, meanwhile, oxygen and moisture in the air and the added ozone can generate a large number of nascent hydrogen, active oxygen, hydroxyl oxygen and other active groups under the action of the light quanta, a part of VOCs substances can also react with the active groups and finally be converted into CO 2 And H 2 O and other harmless substances, thereby achieving the purpose of removing vocs gas.
The UV photolysis oxidation process is technically characterized in that: the average energy of light quanta generated by the UV excitation light source is 1eV-7eV, the proper control of the reaction conditions can realize that the chemical reaction which is difficult to realize under normal conditions or has very low speed can be very fast, the UV photolysis device breaks down, oxidizes and decomposes toxic and harmful chemical molecular chains in the waste gas, such as ethanol, glycol, ether, ketone, ester, aliphatic matters and aromatic hydrocarbons, breaks down, decomposes the macromolecular chains into nontoxic and harmless small molecules, light and gas completely have no gap, the speed of light is several times higher than that of the gas, and in the photo-oxygen catalytic purifier, the-C section light source can completely decompose toxic and harmful organic waste gas, and most of harmful substances in the gas are decomposed and oxidized into carbon dioxide, water and mineral matters without secondary pollution; the effect of removing VOCS is up to more than 90%, the impact load resistance is low, the deodorizing system has small resistance, the operation is simple and convenient, and the deodorizing agent is nontoxic and harmless and has no side effect.
UV photodissociation oxidation unit in market all is by ultraviolet lamp emission ultraviolet light, therefore just very important to the step wind of waste gas, extension waste gas and ultraviolet light's contact time are favorable to the oxidative photodissociation of waste gas, and most UV photodissociation oxidation unit is not very scientific to the wind distribution of waste gas at present, generally just introduces waste gas through the fan, makes it contact with ultraviolet light.
