Abstract
The present invention discloses a method for treating oily odour gas. Said method includes the following several steps: making the oily waste gas be passed through walnut shell filler, then undergone the spray treatment by using atomization spraying device over the walnut shell filler, then undergone the processes of biological method and/or ion oxygen method treatment, so that the oily waste gas can be greatly purified and cleaned.
Description
Technical field:
The present invention relates to a kind of purification method of oil-containing waste gas.
Background technology:
Oil plant, refinery factory, oil recovery factory, refinery Sewage Disposal (factory) all have the discharge of oil-containing waste gas to put, in the exhaust gas discharged, contain multiple compositions such as oily matter, odor pollutant, for example oil, hydrocarbon, benzene, phenol, hydrogen sulfide, organic sulfur, amino etc., thereby easily being deposited on filling surface, oiliness liquid influences the mass transfer of filler and the metabolism of microorganism, the oily matter steady chemical structure does not have the method for well oil-containing waste gas being handled simultaneously.
For a long time, because oil-containing exhaust gas constituents complexity owing to can't can only directly discharge or handle with active carbon adsorption with traditional firing method, chemical Treatment, therefore, does not have good method to solve for low concentration oil-containing waste gas all the time.Long-time a large amount of oil-containing toxic emission has not only caused environmental pollution, has also caused the waste of the energy.
Summary of the invention:
The object of the present invention is to provide a kind of oil that can low-cost effectively remove in the oily odour gas, the improvement method of the oily odour gas of good purification.
Technical solution of the present invention is:
A kind of improvement method of oily odour gas is characterized in that: comprise the following steps:
(1) oil-containing waste gas is passed through from the walnut shell filler, and handle through the spray of the atomizing sprayer above the walnut shell filler;
(2) will handle through bioanalysis and/or ion-oxygen facture through the waste gas that step (1) is handled.
Adopt when bioanalysis is handled waste gas process biologic packing material, and handle through the spray of the spray equipment above biologic packing material.The oil-water mixture that spray is handled carries out oil, moisture from processing through oil water separator.
Pretreatment section of the present invention is utilized the suction-operated of walnut shell surface to oil, catches the oil in the oil-containing waste gas, thereby reaches the purpose that purifies oil-containing waste gas.Walnut shell has hardness height, wear-resistant, characteristics that crushing resistance is good, and stable chemical performance is not dissolved in acid, alkali, high adsorption capacity, and good hydrophilic property, grease resistance is strong, and filtrate does not lump, and is not perishable.Bioanalysis processing section of the present utility model utilizes biologic packing material, and biologic packing material is the filler of inertia, bigger serface, hangs biomembranous form or other biological form of bio-carrier.Pretreatment section main purpose of the present invention is oil and the part odor pollutant of removing in the oily odour gas, and the bioanalysis processing section mainly is to remove odor pollutant, and the ion-oxygen processing section can be to the further oxidation processes of the material that is untreated.The present invention is pure air effectively, safety and environmental protection, consumes energy not, non-secondary pollution.It is remarkable, simple, reliable, practical that the present invention purifies oil-containing waste gas effect.Can be widely used in the recycling of oil in the purification of the local oil-containing waste gas that produces such as oil plant, grease factory, Paint Factory, textile printing and dyeing factory and the waste gas.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the structure chart that one embodiment of the invention is used purifier.
The specific embodiment:
A kind of improvement method of oily odour gas comprises the following steps:
(1) will pass through in the walnut shell packing layer 2 in the calm device 1 of oil-containing waste gas, and handle through 3 sprays of the atomizing sprayer above walnut shell packing layer 2;
(2) waste gas that will handle through step (1) is through biologic packing material 4, and handles through the spray of the spray equipment above biologic packing material 4;
(3) will handle through ion-oxygen treating apparatus 5 through the waste gas that step (2) is handled.
In the cyclic water tank 7, the oil-water mixture that waste gas is handled through spray carries out oil, moisture from processing through oil water separator 6, and oil is separated, and water can come back in the cyclic water tank 7 and reuse.Because the effect of spray recirculated water makes walnut shell constantly be cleaned and washes away, thereby guarantee that walnut shell can carry out repetition, the long-term use.
Cyclic water tank can also be a water-oil separating formula cyclic water tank, and as being provided with aerator etc. in the cyclic water tank, the oil-water mixture that spray is handled can be with the oil in aeration or the additive method removal water.
Walnut shell can be without the form of special processing or through the form of break process, or is bonded to forms such as polyhedron form or graininess after break process again.
Also the waste gas after handling through step (1) only can be handled or only handled through the ion-oxygen method again through bioanalysis again among the present invention.
Claims (3)
1, a kind of improvement method of oily odour gas is characterized in that: comprise the following steps:
(1) oil-containing waste gas is passed through from the walnut shell filler, and handle through the spray of the atomizing sprayer above the walnut shell filler;
(2) will handle through bioanalysis and/or ion-oxygen facture through the waste gas that step (1) is handled.
2, the improvement method of oily odour gas according to claim 1 is characterized in that: adopt when bioanalysis is handled waste gas process biologic packing material, and handle through the spray of the spray equipment above biologic packing material.
3, the improvement method of oily odour gas according to claim 1 and 2 is characterized in that: the oil-water mixture that spray is handled, carry out oil, moisture from processing through oil water separator.
