Description

A kind of device processing organic exhaust gas based on plasma body cooperative ultraviolet catalytic
Technical field
The invention belongs to environmental protection technical field, relate to a kind of device processing organic exhaust gas based on plasma body cooperative ultraviolet catalytic.
Background technology
Volatile organic matter is the presoma of photochemical fog, and photochemical fog can cause environmental pollution, infringement human health. Volatile organic matter is also considered as the predecessor of ground or Tropospheric ozone, and ozone is the important component of photochemical fog. Ozone can pass through Diffusion of gas stream, and institute influence area is far from generation seedbed, destroys forest ecosystem and crops. The another kind of environmental problem caused due to Volatile organic emissions is global warming. Some volatile organic matters, particularly halogenated compound, as greenhouse gases, cause that global warming potential exceedes the order of magnitude of carbon dioxide. Contact volatile organic matter may result in a series of disease: from slight symptom, for instance stimulates, to very serious impact, for instance cancer. Contact during volatile organic matter or soon afterwards, eyes and respiratory tract are modal acute symptoms. Other contact volatile organic matters performances include headache, feel sick, dizziness, fatigue, visual disorder, allergic skin reaction, dysmnesia.
In air, the discharge of volatile organic matter comes from nature, mankind's activity. Nature or biological origin include vegetation, forest fire, animal. Artificial source can be divided into following four primary categories, including transport (automobile, Truck, Airplane, Boat oceangoing ship, agricultural and Architectural Equipment), organic solvent and the use (paint, ink, glue, binding agent, antifreezing agent etc.) containing solvent product, production process and storage (chemical plant, pharmaceutical production, paper mill, food processing factory etc.), combustion process (coal, timber, oil, gas etc. burn).
The current organic exhaust gas techniques available removed containing volatile organic matter includes absorption method, absorption process, Biological fitler method, condensation method, membrane separation process, thermal oxidation method, catalytic oxidation, photocatalytic method, plasma method etc., and every kind of method has respective pluses and minuses. Owing to volatile organic matter decomposes relevant to environmental studies, therefore decomposing volatile organic matters is also popular research theme. Between the several years in past, utilize low temperature plasma or low temperature plasma with catalytic phase in conjunction with voloxidation Organic substance, attract more and more people to pay close attention to. The advantage that Cement Composite Treated by Plasma is burnt compared to heat is in that: without processing condensed water or saturated adsorbent. On the other hand, plasma application is likely to be subject to the restriction of its power consumption. Additionally, due to its high energy characteristic, it is difficult to control the generation of some by-products, for instance carbon monoxide, nitrogen oxides, ozone, and these must be processed. Use catalysis is combined with plasma and processes these problems is a promising solution.
Summary of the invention
