Uv - line photolysis and plasma are the two most commonly used methods for organic gas degradation.Both of these methods can decompose the organic components in the exhaust gas into free water and carbon dioxide, preventing secondary pollution, but both methods still have their own advantages.Thus, the ultraviolet lamp emits 185nm ultraviolet radiation, which serves as an oxidation reactant.
The 254nm ultraviolet radiation emitted by the tube provides the necessary reaction conditions for the photolysis reaction.But ultraviolet ozone tube produce ability is low, such as is now the most commonly used 150 wu form uv set oxygen tubes under the condition of sufficient oxygen every water fountain oxygen quantity is about 900 mg, namely the units of power per hour ozone quantity only for 6 mg I w as a major photolysis reactions of reactive material, its output directly affects the treatment effect is good or bad.
Plasma technology USES an electric field at high pressure to remove O from the air and create O.The efficiency of the body protection is much higher than that of the lamp tube.For example, the 60W plasma tube produced by mitsui environmental protection company produces about 6000mg of oxygen per hour, that is, the maximum ordoxic oxygen per hour produced by the unit force rate is 100mg/w, which is 16 times the ozone production per unit power of the tight outer lamp tube.However, the plasma tube hardly emits ultraviolet light, which lacks the chemical effect of the outside line.The slow and difficult reaction of ozone and organic waste gas also limits the treatment efficiency of the equipment.
Therefore, we try to combine these two treatment schemes and arrange the plasma device in the front section of the photolysis equipment.At the same time, under the influence of the outside line of the 254mm lamp, the reaction efficiency of 0 with organic matter is greatly improved, so as to achieve the ideal treatment effect. Because the installed surface of the house is much higher than that of the shadow lamp, the power consumption of the equipment is reduced, and the energy saving effect is significant.
