Description
[technical field]
The utility model relates to a kind of emission-control equipment, particularly a kind of organic exhaust gas absorption and desorption treating apparatus.
[background technology]
Organic exhaust gas improvement technology mainly contains condensation method, absorption process, firing method, Production by Catalytic Combustion Process, absorption method and absorption-Production by Catalytic Combustion Process etc. at present, and the new method of abroad studying, and also has biological method purification VOC technology, ionization technology etc.
(1), condensation method
This law is that waste gas is directly imported condenser condenses, and condensate liquid is through separating recyclable valuable organic matter.Adopt condensation method to require organic concentration height in the waste gas, general organic concentration will reach several ten thousand even hundreds of thousands ppm.Inapplicable for this method of low-concentration organic exhaust gas.
(2), absorption process
Absorption process can be divided into chemical absorbing and Physical Absorption, and most of organic exhaust gas should not adopt chemical absorbing.Physical Absorption be in the waste gas one or more components dissolved in selected liquid-absorbant, this law is suitable for the waste gas of middle and high concentration, but select a kind of low volatility absorption liquid of Cheap highly effective also relatively more difficult, the problem of secondary pollution simultaneously can't solve, and clean-up effect is undesirable.
(3), firing method
Firing method is to utilize auxiliary fuel burning liberated heats such as combustion gas or fuel oil that mist is heated to uniform temperature (700～800 ℃), the resident regular hour (0.3～0.5 second), makes flammable harmful substance carry out pyrolytic and becomes innocuous substance.This law is suitable for high-concentration waste gas and administers; Shortcoming is that energy consumption is big, and operating cost is higher more than 10 times than Production by Catalytic Combustion Process, and running technology requires high, wayward and grasp.
(4), Production by Catalytic Combustion Process
This law is that waste gas is heated to carbon dioxide and the water that 200～300 ℃ of process catalytic bed catalytic combustions change into harmless odorless, reaches the purification purpose.The characteristics of this law: initiation temperature is low, energy savings; The purifying rate height, non-secondary pollution; Technology is simple, and is easy to operate, and security is good; Device volume is little, and floor space is few; The maintenance and the depreciation cost of equipment are lower.This method is applicable to the organic exhaust gas improvement of high temperature, middle and high concentration, and existing both at home and abroad widely used experience is respond well.This method is one of effective ways of administering organic exhaust gas.
(5), absorption method
A. direct active carbon adsorption
Organic exhaust gas can reach 95% purifying rate by the absorption of active carbon, and equipment is simple, investment is little.Shortcoming is that system can not regenerate to adsorbing saturated active carbon, and often the active carbon requirement of changing is very big, and spillage of material is big, and operating cost is quite high.
B. adsorb--absorption method
This method is utilized adsorbents adsorb " triphen " waste gas such as fiber-reactive charcoal, near saturated back carrying out desorption and regeneration with superheated vapour blowback active carbon, " triphen " gas that water vapour and desorption come out through condensation, separate recyclable " triphen " liquid.This method purification efficiency is higher, but requires to provide the quantity of steam of necessity." triphen " solvent is not really thorough with separating of water in addition, and " benzene mixed " liquid quality that obtains is not high, and steam condensation effect and equipment operation safety problem also need to be resolved hurrily.This method still awaits improving on technology.
(6), absorption--Production by Catalytic Combustion Process
Use the organic exhaust gas of novel absorbent charcoal (mostly being honeycomb briquet or fiber charcoal) absorption concentrating low-concentration, absorption is introduced the hot air active carbon near saturated back, make " triphen " waste gas desorption come out to enter the catalytic combustion bed and carry out the flameless combustion purified treatment, hot gas recycles or sets up secondary heat exchanger and carries out energy recovery in system.This method is passed through catalytic combustion bed with its thorough purification by active carbon with its organic exhaust gas that is condensed into high concentration with the organic exhaust gas of low concentration again.This method has been drawn the advantage of absorption method and Production by Catalytic Combustion Process, has overcome the shortcoming of using separately separately, has solved a difficult problem of administering low concentration, big air quantity organic exhaust gas existence, is the maturation of present domestic improvement organic exhaust gas, practical method.
(7), ionization method
Shine waste gas with electron beam, VOC chemical bond is wherein ruptured.The equipment that produces electron beam at present is also relatively more expensive.
(8), bioanalysis
