Description
Technical field
The invention belongs to the process of organic exhaust gas, particularly relate to a kind of organic exhaust gas processing method and
Organic waste gas treatment system.
Background technology
Along with the development of petrochemical industry, application industry, Printing Industry and transportation industry etc., have
Machine waste gas is the most increasingly severe to the pollution of atmospheric environment, has influence on human physical and mental health and animals and plants
Grow up healthy and sound.Current Some Enterprises exists the unsound problem of emission mechanism makes organic exhaust gas without having
Effect process is up to standard to be just discharged in the middle of air, thus causes the pollution of atmospheric environment.Therefore, strengthen
Strength disposal to organic exhaust gas, the treatment technology improving organic exhaust gas has very great significance.
At present, in terms of VOCs treatment, define the Technology of some comparative maturities,
Mainly include Production by Catalytic Combustion Process, photocatalytic oxidation, membrane separation process, absorption method etc..
Production by Catalytic Combustion Process refers at a lower temperature, makes flammable group in waste gas under the effect of catalyst
Divide exhaustive oxidation to decompose, generate nontoxic CO2And H2O, so that waste gas is purified the side of process
Method, the advantage of the method is that purifying rate is higher, and up to less than 95%, the product of production is H2O and
CO2, the problem of non-secondary pollution.Shortcoming is needs fuel, and catalyst mostly is noble metal material, becomes
This is higher.
Photocatalytic oxidation is photocatalyst such as TiO2It is activated under ultraviolet irradiation, makes H2O is raw
Becoming OH free radical, then organic pollution is oxidized to CO by OH free radical2And H2O.Photocatalysis
The device structure of the advantage of oxidizing process is simple, and operating cost is low, and shortcoming is affected by catalyst degradation efficiency
Impact, removal efficiency is unstable.
Membrane separation process cleaning organic waste gas is different with the ability of air permeable film according to organic steam,
And the two is separate.Conventional membrane separation process has: water vapour penetration, gaseous jet simulation and membrane-base absorption
Method.Membrane separation technique is that investment cost is low, separation factor big for the advantage in gas purification, purifies
Effective, and embrane method purification run is simple, easy to control, operating flexibility is big；Its shortcoming is membrane material
Cost is high, is particularly easy to pollute simultaneously, is not easy to recover after pollution.The prevention and cure of pollution of membrane material are generation
A difficult problem for criticality.
Absorption method is mainly used in, high flux can wave the organic process of method.Determine that absorption method processes
VOCs's it is crucial that adsorbing material, adsorbing material should have intensive pore structure, internal surface area big,
Absorption property is good, stable chemical nature, the most broken, to performances such as air drag are little, conventional has
Activated carbon and zeolite.Wherein the main process of Activated Zeolite Adsorption is zeolite runner concentration technology.Its
Technological principle is after waste gas passes through zeolite concentration rotating wheel, can effectively be adsorbed in zeolite, reaches to remove
Purpose.Through the clean gas of the volatile organic matter of zeolite adsorption, directly arrived by smoke stack emission
In air, the speed that runner continues so that 1-6 per hour turns rotates, and the volatility by absorption is organic simultaneously
Thing is sent to be desorbed district.Utilize a small gangs of to add hot gas in desorption district to be taken off by volatile organic matter
Attached, the zeolite runner after desorption rotates to adsorption zone, persistently adsorbs volatile organic gas.After desorption
Concentration organic exhaust gas deliver to incinerator and carry out burning conversion and become carbon dioxide and moisture discharge to greatly
In gas.The advantage of this technique is that safety is good, purification efficiency higher up to less than 95%, can be the most steady
Fixed operation.Shortcoming is that zeolite needs to carry out special machine-shaping, cost in order to adapt to required for technique
High；The method that the desorption and regeneration of zeolite uses is full-boiled process desorption, and the Organic substance through being desorbed passes through oxidation furnace
Carrying out high temperature oxidation process, technological process is complicated, and energy consumption is high.
