Described adsorbent equipment adopts 0.3MPa nitrogen to be purged by activated carbon of sorbent in adsorbent equipment, regenerating active carbon; The gas and liquid mixture purged out is sent to condensation in condenser and reclaims, and carries out gas-liquid separation.
In described aqueous phase absorbing path, absorption plant is set, absorption plant is built with Bao Weier ring filler, the absorbent of proportioning adopts running water or alkalescent water as absorbent, and the discharging of waste liquid after absorption plant absorbs is in waste treatment device, and lean gas enters in adsorbent equipment and carries out adsorption treatment.
Be provided with condensing unit in described condensation channel, condensation temperature is arranged carries out correspondence setting according to the condensation point of plurality of liquid Organic Chemicals; Condensed coagulating liq sends into waste liquid recovery apparatus, and lean gas enters adsorption device adsorbs process.
The desorption of described adsorbent equipment adopts 0.3MPa supersaturated vapor to be blown in adsorbent equipment, by the VOC blowout be adsorbed in adsorbent equipment, condensing cooling is carried out along with steam enters condenser cooling together containing VOC, then, dry up adsorbent equipment with 0.3MPa nitrogen, wait for and enter next adsorption cycle.
Described adsorbent equipment at least comprises 2 absorbers, and wherein, at least 1 is carried out adsorption operations, and other absorber carries out desorption manipulation, and absorber is the absorber that activated carbon is housed.
It is any number of that described plurality of liquid Organic Chemicals Volatile Gas comprises in following gas: furfural, propane diols, octanol, ethylene glycol, ortho-aminotoluene, tripropylene glycol, aniline, diesel oil, ethanol, acetone, butanone, acetic acid, isopropyl alcohol, methyl alcohol, acrylic acid, naphtha, gasoline, methyl-tert, purified petroleum benzin, toluene, paraxylene, ortho-xylene, styrene, nonene, mixed xylenes, vinylacetate, methyl acrylate, butanols etc.
From the material enumerating out, volatilize organic steam, can find out have alcohols, organic acid, ester class, benzene class, aldoketones, ethers and fuel oil; From the boiling point of the kind listed, distribution is very wide, from 20 DEG C to 316 DEG C; From the polymerism of the kind listed, it is polymerisable for always having 5 kinds, when collecting process, is the key factor needing to consider; From the metal protection angle of the kind listed, two kinds of organic acids have stronger corrosivity; From the reactivity of the kind listed, potential reaction is the esterification of acid and alcohol.But this reaction belongs to reversible reaction, and gentleness is even slow.What add collection is thin volatilization steam, so the mixing of two kinds of potential reaction things is completely not dangerous in collection process; Boiling point from enumerating kind: furfural, propane diols, octanol, ethylene glycol, ortho-aminotoluene, tripropylene glycol are distributed in 167 DEG C ~ 316 DEG C, and gaseous volatilization amount is very little, can not consider the collection process of its volatilization steam.
The present invention has carried out making rational planning for for collection scheme and has collected process: the recovery of consideration is because have boiling point, reactivity, corrosivity, polymerism and freezing point etc.
1.: organic acid: due to organic acid corrosivity, in order to reduce its corrosion to equipment as possible, making it be neutralized as early as possible is best scheme.In weakly alkaline solution, there is very high solubility due to organic acid and be neutralized immediately after dissolving, so allow the absorption plant of two kinds of organic acids (acetic acid, acrylic acid) first-selection by taking sodium carbonate liquor as absorbent.The acid gas that tail gas after obtaining absorption plant in absorbing path has contained is little, by discharging after active carbon adsorption equipment in put-through channel.
2.: water-soluble kind: there is Wastewater Concentrated in general place, considers several water-soluble kind, acetone, methyl alcohol, butanone, ethanol, isopropyl alcohol, acrylic acid and ethylene glycol etc., all absorbs through absorption plant.Here can with 1. use same absorption plant.The mixing of several material, comprises the reaction of organic acid and alkalescent solvent, obviously can not affect absorptivity.And the sewage treatment plant that the organic aqueous solution after cyclic absorption directly can be sent to warehouse district focuses on.Due to without the need to there being the professional liquid waste processing of qualification, this has saved a considerable subsequent treatment expense for owner.
3.: higher and the water-insoluble or slightly soluble kind of condensation point: have naphtha, methyl tertiary butyl ether(MTBE), purified petroleum benzin, toluene, paraxylene, ortho-xylene, styrene, nonene, octanol, gasoline, diesel oil, mixed xylenes, vinylacetate, methyl acrylate, butanols, ortho-aminotoluene, furfural etc.
Boiling point distribution 20 DEG C ~ 200 DEG C.If consider to absorb it, absorbing liquid must be oil-soluble, such as poor gasoline, diesel oil etc.And these absorbing liquids are expensive, and the rich solution after absorbing can affect the composition changing absorbing liquid.Rich solution must could realize product characteristics after oil plant distills.And this is a series of problem for owner, huge freight charges back and forth, the usage charges of absorbing liquid, absorbing liquid processing charges returning oil plant etc.So design here absorbs and does not very possess economy.If follow-up adsorbent equipment is enough large, can considers directly to be sent to adsorbent equipment in absorbing path and adsorb.But consider that in temperature in summer high season, vapour concentration is very high, there will be absorption switch situation frequently if directly carry out absorption.This not only adds the energy consumption of desorption, and can shorten the life-span of active carbon to a certain extent.So be water-insoluble variety development condensation channel here, condensation temperature+10 DEG C ~-45 DEG C.Different condensation temperatures is selected to different steam, the organic steam more than 70% can be made to liquefy.Significantly reduce the load of follow-up adsorbent equipment like this.
4. polymerisable kind: vinylacetate, methyl acrylate, acrylic acid, styrene, nonene etc.
Polymerisation in HTHP situation is violent, and polymerization is exothermic reaction.If the steam of high concentration enters sorption channel, heat of adsorption can bring out polymerization.Although due to temperature and pressure reason, reaction here can not be very violent, perfectly safe in order at secure context, must reduce the vapour concentration entering absorber as possible.Consider from another point of view, if polymerisation is too much in absorber, the life-span of the too fast consumption active carbon of meeting.So this kind of material is introduced into condensation channel, and reduces condensation temperature more than freezing point as far as possible.
By analyzing above, all materials are divided into the recycling of 3 kinds of techniques by chemical property, that is: put-through channel (kind of low condensation point), aqueous phase absorbing path (water-soluble+organic acid kind), condensation channel (condensation point is higher and insoluble or be slightly soluble in the kind of water).System is carried out intelligent selection and is gone out the most effective the most applicable recovery process and operate.Realize high efficiency collection to control, low energy consumption, work safety and reliability, discharges the features such as cleaner.
Processing method of the present invention has significant advantage and effect compared with similar technique:
1) start enters the program of intelligent selection technique, as long as operative employee inputs this by the title of material (one or more) to be processed, system can select best treatment process scheme.
2) because system makes different technique and parameter to measure to different material, make the removal process of corresponding volatilization steam energy-efficient.
3) owing to arranging adsorbent bed before end discharge, make exhaust emissions cleaner, more easily up to standard.
4) systems soft ware arranges upgrading space.When the material kind of discharge region increases to some extent, to system upgrade, the collection process of the Volatile Gas of increased kind can be included in.
The intelligent centralized collection of plurality of liquid Organic Chemicals Volatile Gas, adopt the PROCESS FOR TREATMENT passage of compound, collection plurality of liquid Organic Chemicals Volatile Gas is caused to be integrated in a recovery system, this method solve plurality of liquid Organic Chemicals Volatile Gas to volatilize the air pollution caused, make the discharge of Volatile Gas reach the requirement of environmental protection air pollution emission control criterion.The method is widely used in reclaiming produces and the volatile organic compounds of plurality of liquid such as turnover of storing in a warehouse from petroleum chemical industry.

When dispatching a car as material 1#, system is carried out intelligent selection and is gone out the most effective the most applicable recovery process and operate, be i.e. put-through channel.The Volatile Gas produced during organic compound of dispatching a car enters adsorbent equipment through put-through channel and adsorbs, and is provided with 2 absorbers herein, and inner active carbon of placing is as adsorbent.When absorber 1 adsorbs, as VOCs concentration analyzer on blow-down pipe, detect emission and reach setting value, be switched to absorber 2 and adsorb, and now absorber 1 0.3MPa superheated steam desorption manipulation.From active carbon, desorption gas-liquid mixture out enters into condensing plant (shell-and-tube cooler etc.) and carries out condensation recovery.Isolated liquid enters in devil liquor recovery equipment and temporarily stores, after the lean gas do not reclaimed enters into condensation channel circulation, after entering into absorber 2 absorption of adsorbing.Absorber 1 after steam desorption, purge absorber and pipeline by nitrogen, carry out regenerating active carbon, the absorber 1 after regeneration is standby, waits for that absorber 2 switches after saturated, completes 1 organic steam reclaimer operation.
During as dispatched a car as material 2#, system is carried out intelligent selection and is gone out the most effective the most applicable recovery process and operate, be i.e. absorbing path.The Volatile Gas produced during organic compound of dispatching a car enters aqueous phase absorbing path.Because there being water-soluble+organic acid in material, adopting alkalescent solvent as absorbent here, considering organic acid corrosivity in material of dispatching a car, in order to reduce its corrosion to equipment as possible, making it be neutralized recovery as early as possible.Organic steam enters into absorbing path and obtains absorption plant, is sprayed and Pall ring filler, organic steam is fully contacted with absorbent, reach the object of recovery by absorbing liquid.Enter into put-through channel and adsorbent equipment again without the organic poor steam absorbed, carry out adsorbing, steam desorption, condensation recovery, nitrogen purging process, reach the object reclaiming and produce organic steam when dispatching a car.
During as dispatched a car as material 3#, system is carried out intelligent selection and is gone out the most effective the most applicable recovery process and operate, be i.e. condensation channel+put-through channel.The Volatile Gas produced during organic compound of dispatching a car enters condensation channel.Because the condensation point of 3# material is distributed more widely, what particularly have in these 13 kinds has higher setting temperature, if condensation temperature controls bad, organic steam can be made to condense in passage, and cause circulation not smooth, condensation efficiency declines even by channel blockage.So for different materials, different condensation temperatures is set.Interface is set in automatic running program design temperature, easily suitable condensation temperature can be set for different materials, reclaims.Organic poor steam without condensation enters into put-through channel (adsorbent equipment) again, carry out adsorbing, steam desorption, condensation recovery, nitrogen purging process, reach the object reclaiming and produce organic steam when dispatching a car.
Above example illustrates the intelligent centralized collection processing method reclaiming plurality of liquid Organic Chemicals Volatile Gas, but in fact, the method is not limited only to the application that example is mentioned, it also can be applied in the recovery of the plurality of liquid Organic Chemicals Volatile Gas that oil, Chemical Manufacture factory etc. emit, although, the Volatile Gas kind emitted in above-mentioned industry device may be different, but it reclaims principle and method is identical.The accessible material quantity of system is unrestricted.But, vigorous reaction, violent material that is that be polymerized or very exothermic dissolving at normal temperatures and pressures cannot be had.When adsorbent bed is close to penetrating, the organic vapor concentrations of tail gas increases, and provides signal at the organic gas detector of exhaust port.Stop adsorbing and starting desorption.This method 0.3MPa saturated vapor desorption, the mist of desorption is sent to the process of waste tank etc. professional institution after condensation.
More than describing is explanation of the invention, and be not limitation of the invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
