Abstract
The present invention discloses a method for removing oil from oil waste gas. It is characterized by that said method includes the following steps: making the oily waste gas be passed through walnut shell filler, then undergone the process of spray treatment by means of atomization spray device over the walnut shell filler, so that said invention can attain the foal of purifying oily waste gas.
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 oily matter, thereby, oiliness liquid influences the mass transfer of filler and the metabolism of microorganism and easily being deposited on filling surface, 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 oil-containing waste gas, the deoiling method of the oil-containing waste gas of good purification.
Technical solution of the present invention is:
A kind of deoiling method of oil-containing waste gas is characterized in that: 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.
Oil-containing waste gas is handled through the atomizing sprayer spray of multistage walnut shell filler and every grade of walnut shell filler top.The oil-water mixture that spray is handled carries out oil, moisture from processing through oil water separator.
The present invention utilizes 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.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.
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the degreasing unit that one embodiment of the invention adopts.
The specific embodiment:
A kind of deoiling method of oil-containing waste gas will pass through in the walnut shell packing layer 2 in the calm device 1 of oil-containing waste gas, and handles through 3 sprays of the spray equipment with atomizer above walnut shell packing layer 2, and spray equipment 3 communicates with cyclic water tank 4 through circulating pump.Oil-containing waste gas is to handle through the spray equipment spray of multistage walnut shell filler and every grade of walnut shell filler top.The oil-water mixture that spray is handled in the container 1 bottom cycle water tank 4 carries out oil, moisture from processing through oil water separator 5, and oil is separated, and water can come back in the cyclic water tank 4 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.
