Description

A kind of industry spraying exhaust gas purifying treatment system
Technical field
A kind of lacquer spraying waste gas processing system is the utility model is related to, is specially a kind of industry spraying waste gas purification processing system System, belongs to industrial waste gas process field.
Background technology
With the development and progress in epoch, industrial production is also with fast development, the pollution of thing followed industrial waste gas It is increasingly serious, and just include the lacquer spraying waste gas that air quantity is big, organic concentration is relatively low in industrial waste gas pollution, industrial The spray painting stage produces a large amount of organic exhaust gas, although there is the facility of purification treatment, treatment effect unobvious, still to workshop with The environment on periphery brings more serious influence, while original purification apparatus design comparison old stuff, does not use activated carbon again Raw technology so that later stage operating cost is higher and management is inconvenient.The method species of processing organic exhaust gas is various at present, and feature is each It is different, therefore the administering method accordingly used is also different, conventional has condensation method, absorption process, combustion method, catalysis method, absorption Method etc., brief comparison introduction is made to each technique below.
(1)Condense absorption method
This method waste gas is directly condensed or Adsorption Concentration after condense, condensate liquid through separate and recover it is valuable organic Thing.The method is used for concentration height, the exhaust-gas treatment that temperature is low, air quantity is small.But the investment of this method is big, high energy consumption, operating cost are big, therefore Without special requirement, this method is not used typically.
(2)Absorption process
Absorption process can be divided into chemical absorbing and Physical Absorption, and most of organic exhaust gas should not use chemical absorbing.Physics is inhaled Receipts require that absorbent should have and have higher affinity with absorbent components, low volatility, through parsing or rectifying after absorbing liquid saturation After reuse.This law is suitable for the waste gas of middle and high concentration, but to select a kind of low volatility absorbing liquid of Cheap highly effective also to compare It is more difficult, while secondary pollution problem is relatively difficult to resolve certainly, clean-up effect is undesirable.So this programme it is not recommended that using.
(3)Direct combustion method
This law is also known as thermal oxidation method, flame combustion method, is the heat released using aid fuel combustions such as combustion gas or fuel oils Mixed gas is heated to certain temperature (700~800 DEG C) by amount, is resident the regular hour (0.3~0.5 second), makes flammable to have Evil material carries out pyrolytic and is changed into innocuous substance.The characteristics of this law:Technique is simple, is applicable high-concentration waste gas administers;For certainly The aphlogistic middle low concentration tail gas of body, generally needs combustion adjuvant or heating, and energy consumption is big(Operating cost is higher than Production by Catalytic Combustion Process 10 times More than);Running technology requires high, is difficult to control and grasps.This method does not obtain popularization substantially at home, and only a small number of producers introduce External abatement equipment is applied in higher concentration and the tank tin graphed sheet industry waste gas pollution control and treatment processed of temperature, but eventually because energy consumption is big and operation is unstable It is fixed, it is difficult to run well.So this programme also it is not recommended that using.
(4)Production by Catalytic Combustion Process
The method is that waste gas is heated into 200 ~ 300 DEG C to burn by catalytic bed, reaches purification purpose.Its advantage is energy consumption It is low, purifying rate is high, non-secondary pollution, technique simple operations are convenient.Suitable for the VOCs treatment of high-temperature high concentration, do not apply to In low concentration, the VOCs treatment of Wind Volume.Combustible burns under catalyst action, compared with directly burning, catalysis combustion Burning temperature is relatively low, and ratio of combustion is more complete.
(5)Absorption method
(1) direct active carbon adsorption
Organic exhaust gas can reach more than 90% purifying rate, equipment is simple, investment is small by the absorption of activated carbon.The method is not The activated carbon of adsorption saturation can be regenerated, it is desirable to often change activated carbon to ensure clean-up effect, cause to load and unload, transport During cause secondary pollution, and the activated carbon requirement often changed is very big, and spillage of material is big, and operating cost is at a relatively high.
(2) adsorb -- absorption method
The method carries out desorption and regeneration using the adsorbent of superheated steam blowback adsorption saturation, and steam comes out organic with desorption Gas is condensed, separation, recyclable organic liquid.The method purification efficiency is higher, but requires to provide necessary quantity of steam.Have in addition The separation of solvent and water is not bery thorough, and obtained " benzene mixed " liquor quality is not high, and component is complex, these organic liquids Directly can not use in production, again using the multiprogramming such as distillation, rectifying, extraction, separation, and steam condensation effect with set It is also urgently to be resolved hurrily that received shipment turns safety problem.The method still has much room for improvement in technology.
(3) novel adsorption -- catalytic oxidation
Using novel absorbent charcoal(Mostly honeycomb briquet or fiber charcoal)The organic exhaust gas of Adsorption Concentration low concentration, adsorb close to full With rear introducing hot air activated carbon, organic exhaust gas is set to be desorbed out at the progress flameless combustion purification of catalysis oxidation bed Reason, hot gas recycle or set up in systems secondary heat exchanger and carry out energy recovery.The method is by the organic exhaust gas of low concentration The organic exhaust gas of high concentration is condensed into again by being catalyzed thoroughly purification of burning by activated carbon.The method drawn absorption method and The advantages of Production by Catalytic Combustion Process, the shortcomings that overcoming respective exclusive use, solve and administer low concentration, Wind Volume organic exhaust gas is present Problem, be the current domestic maturation for administering organic exhaust gas, practical method.
(6)Bioanalysis
The method is that the biological treatment of sewage based on maturation technically grows up, and has the spy that energy consumption is low, operating cost is few Point, there is the application of certain scale abroad.Its shortcoming is needing enough stops in pollutant in mass transfer and digestion process Time, so as to increase the occupation of land of equipment, simultaneously because microorganism has certain anti impulsion load limit value, add whole place Control of the reason system in stop and start.There is a small amount of application in the current sewage plant waste gas pollution control and treatment at home of the method, industrial waste gas is administered Application it is seldom.Therefore, a kind of industry spraying exhaust gas purifying treatment system is proposed regarding to the issue above.
