Description

VOCs low-temperature plasma multiple treating system
Technical field
The utility model relates to chemical adsorbing separation and Pollutant Control Technology FIELD OF THE INVENTIONThe, particularly relates to a kind of VOCs low-temperature plasma multiple treating system.
Background technology
VOCs(Volatile organic compounds) i.e. VOC, it is the common atmosphere pollution of a class, be mainly derived from the waste gas of plant emissions, be common in the industries such as paint production, chemical fibre industry, coated metal, chemical coating, shoemaking process hides, plating, plywood making, Tire production, waste water treatment plant.Harmful VOC mainly comprises acetone, toluene, phenol, dimethylaniline, formaldehyde, n-hexane, ethyl acetate, ethanol etc.
According to the discharge standard of National Industrial waste gas, industrial waste gas must meet its discharge standard when discharging, this just requires in discharge process, VOCs in industrial waste gas need be processed accordingly, traditional mainly comprises the processing method of VOCs: active carbon adsorption, Production by Catalytic Combustion Process, absorption process and biofiltration process, but this several conventional method has respective shortcoming.Active carbon adsorption actual motion costly, active carbon is changed, desorption and after-treatment trouble, regulation effect is difficult to long-term guarantee and monitors at any time, also may there is the multiple factor mixing that can not coexist, cause exothermic reaction and oxidation, polymerisation in active-carbon bed, along with constantly increasing of concentration, there is safety factor scarcely; The equipment that Production by Catalytic Combustion Process uses is perishable, and need consume fuel processing cost high for the gas that concentration is low, catalyst is easily poisoning, easily forms the secondary pollution as dioxin etc. simultaneously; And the byproduct adopting absorption process to produce needs subsequent treatment, to insoluble or be slightly soluble in the gas of water, do not have actual degradation effect, absorbent price height not easily regenerates, and operating cost is high; Biofiltration process has selective to degraded organic factor, biodegradation generally needs the longer time of staying, have certain requirement to the collection in waste gas and construction place, falling stability of solution and need to investigate, also there is certain problem in comprehensive cost aspect.
Therefore, in recent years the exhaust-gas treatment research of low-temperature plasma is attracted attention gradually, plasma is the 4th state of material, namely " gas " that ionized, it presents the labile state highly excited, comprising ion (having distinct symbols and electric charge), electronics, atom and molecule.Lower temperature plasma technology is a cross-synthesis technology integrating physics, chemistry, biology and environmental science.Plasma is rich in one of the most effective technical method of prospect most in current air contaminant treatment both at home and abroad, and this technology distinguishing feature has physical action, chemical action and biological agent concurrently to pollutant.Its catharsis mechanism comprises two aspects:
(1) in the process producing plasma, the moment high-energy that high-frequency discharge produces can open the chemical energy of some pernicious gas molecule, as: ammonia, trimethylamine, hydrogen sulfide, first sulphur hydrogen, methyl mercaptan, methyl sulfide, methyl disulfide, carbon disulfide and styrene, sulfide H2S, VOC class, the molecular chain structure of benzene,toluene,xylene class, makes organic or inorganic macromolecule malodorous compound strand be decomposed into simple substance atom or harmless molecule.
(2) comprise a large amount of high energy electrons, negative ions, excited state particle in plasma and there is the free radical of strong oxidizing property, these active particles and portion molecular collision combine, under electric field action, emission molecule is in excitation state, when emission molecule obtain energy be greater than its molecular bond energy in conjunction with energy time, the molecular scission of emission molecule, Direct Resolution becomes simple substance atom or obtains innocuous gas molecule by single atomic building.Produce simultaneously a large amount of-OH ,-H2O ,-O isoreactivity free radical and the extremely strong O3 of oxidisability, can with pernicious gas molecule generation chemical reaction, finally generate harmless products.
Plasma is a cross discipline comprising on the basic subjects such as discharge physics, discharge chemistry, Chemical Reaction Engineering and vacuum technique, because purification of air environment is different, industrial organic exhaust gas is administered a lot all kinds of, must adopt different processing methods to tackle different environment and different waste gas.The enterprise of current domestic existing many production " low-temperature plasma " organic waste gas treatment equipments, produce market covers industry, business, civilian, but product structure is more single.What substantially all adopt is corona discharge plasma electric field process organic exhaust gas, relatively simple for structure due to corona discharge, and electric field power is more weak, and process range is limited.In face of specific molecular structure, " corona discharge " is even if multistage all not all right with N.Such situation probably to need the temperature of > 0 DEG C as the ice melt into water, iron melt into liquid needs 1535 DEG C, hafnium alloy then wants 4215 DEG C of reasons the same, you can not remove molten iron with the heat energy of molten ice, the heat energy of molten iron removes molten hafnium alloy, if instead go molten ice just to cause the waste of energy consumption and equipment investment by the temperature of 4215 DEG C.
Therefore, because different industries, the exhaust gas constituents of different enterprise, exhaust gas concentration are different, cause single lower temperature plasma technology clearance not high, and containing a large amount of ozone in tail gas after plasma treatment, still can there is the problem of secondary pollution.And for various varying environment, the character of different enterprise, air gap, exhaust gas constituents and concentration, how to calculate accurately, design, control, go back the mode of neither one maturation at present, designing a kind of VOCs low-temperature plasma multiple treating system thus becomes present stage shocking problem to be solved.
