Description
Technical field
The invention belongs to air purification field field, relate to the purification method of machinery plant interior decoration organic exhaust gas under a kind of ISO9001 specifically.
Background technology
With microemulsion process organic exhaust gas, maximum advantage is that reaction condition is simple, and clearance is high, and the characterisitic solution of microemulsion self can be utilized to suck back receipts three benzene homologues.
Along with the raising of living standards of the people, interior decoration is very general.Finishing will use the organic materials such as various paint, coating, foam, plastics, leather, cloth art, and TVOC constantly volatilizees and spills in room air, and serious pollutes indoor environment, becomes the large public hazards of harm people able-bodied.
Atmosphere pollution is one of problem of environmental pollution of giving prominence at present of China, and wherein volatile organic matter is the important sources of atmosphere pollution.A large amount of industrial waste gas containing volatile organic matter enters air, except making air bad border Quality Down, also brings serious harm to health simultaneously, brings about great losses to national economy.As the benzene,toluene,xylene (i.e. three benzene homologues) of the representative pollutant of Typical Volatile Organic waste gas, human body can be entered by respiratory tract and skin, the organs and systems such as the breathing of people, blood, liver can be made to cause temporary or permanent pathology, and especially benzene naphthalene pyrene class polycyclic aromatic hydrocarbon can make human body directly carcinogenic to cause the great attention of the mankind.So, to the major issue that the research of volatile organic matter becomes in current atmospheric pollution control with improvement.At present for low concentration, without volatile organic compounds many employings disruptive method of recovery value as catalytic combustion, corona method or plasma method; Middle and high concentration, the volatile organic compounds having recycling to be worth then adopt non-destructive method as absorption and absorption etc. as far as possible.
Well-known TVOC is one group of apolar substance being insoluble in water, is inflammable volatile harmful chain fatty hydrocarbon; Transfer in fat boat and lipoids histoorgan after being inhaled into human body very soon, then a part write after liver is oxidized glucuronic acid combine discharged by kidney, a part is accumulated in vivo, causes chronic lesion to human body; Also can grievous injury immune system and tip system.But, can only detect up to now and there is no effective governance approach, its reason is the particularity of TVOC structure, stability not easily chemical reaction occurs under determining normal temperature.Above problem has caused the common concern of various circles of society, and looks forward to and can be resolved early.Therefore, how to remove the pollution of TVOC to room air, oneself becomes one of important topic of countries in the world scientific and technical personnel concern.
Benzene homologues is also the important hazardous material in waste gas simultaneously, and how simultaneously removal benzene homologues and TVOC material are the technical problems that emphasis of the present invention solves.Disclose the method for a kind of process containing three benzene homologues waste gas in US5378264 patent application, be specially adapted to the oil-containing waste gas of process for producing aluminium sheet and metal tinfoil paper.Ion and non-ionic surface active agent and alkyl diol are mixed with microemulsion and are used for absorbing oil-containing waste gas by author, when this flushing liquor contacts can form oil-in-water microemulsion with the oils in waste gas, and can oils in Solubilization of Water.
But all there are problems in discussed prior art above.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the present invention is to provide a kind of method of microemulsion to purify organic waste gases, the microemulsion formed with surfactant and cosurfactant, as absorbent, absorbs the waste gas administered containing benzene homologues, can remove TVOC material simultaneously.
At the absorption reaction being suitable for carrying out under condition, harmful substance is wherein detained in the liquid phase, can desorb after absorption reaction.There is the features such as reaction temperature is low, clearance is higher, easy desorb; Microemulsion system activity is high simultaneously, and consumption is few, and absorbent cost is low.
The present invention is achieved through the following technical solutions:
The purification method of machinery plant interior decoration organic exhaust gas under a kind of ISO9001, complete according to the following steps, microemulsion is by surfactant and cosurfactant, in surfactant: cosurfactant mass ratio is the ratio weighing mixing of 1: 10-15, adds water and is mixed with the microemulsion that mass percentage concentration is 95%; The microemulsion prepared is added in reactor, then sodium phosphate trimer is added, sodium phosphate trimer and microemulsion mass ratio are 1:10, eicosyl sulfonate, wherein the mass ratio 1:(10-20 of dodecyl sodium sulfate and microemulsion), active carbon, the mass ratio 1:100-250 of active carbon and microemulsion, control temperature is at 60 DEG C, and pass into containing benzene homologues waste gas, the benzene homologues in waste gas is removed as oil phase.
Compared with prior art the present invention has the following advantages:
1, adopt microemulsion to be absorption system, have that source is wide, price is low, absorbent cost comparatively Traditional Method is low;
2, by using target contaminant as oil phase, and surfactant and cosurfactant directly form microemulsion, overcome the secondary pollution that oil phase causes;
3, this method has that technique is simple, reaction temperature is low, clearance is high and easily desorb;
4, the most important thing is, while removing benzene homologues, to also been removed TVOC material.
Further describe the present invention below by example, but the present invention is not limited to this.
