Description

The purifier of oil-containing waste gas
Technical field
The present invention relates to a kind of processing equipment of waste gas.
Background technology
Waste gas containing oil gas is relatively difficult to process, and had both stain pipeline equipment, and had been easily caused exhaust gas adsorption device again Adsorbing material saturation loses absorbability it is also difficult to parse Regeneration Treatment；Also affect biodegradable effect, even result in biology Processing meanss lost efficacy.
A kind of number of patent application deoiling method of oil-containing waste gas that has been 2006100961108 disclosure of the invention, is characterized in that: Oil-containing waste gas is passed through from walnut shell filler, and through the atomizing sprayer spray process above walnut shell filler.This Bright utilization walnut shell surface, to oily adsorption, catches the oil in oil-containing waste gas, thus reaching the purpose purifying oil-containing waste gas. This invention needs to consume walnut shell, and the waste oil adsorbing is difficult to separation and recovery and utilizes.
The invention for 2015103553186 for the number of patent application provide a kind of purification method of heat setting machine high temperature oil-containing waste gas and its Device, high temperature oil-containing waste gas reclaims the heat energy in waste gas by air-water hot tube high-efficiency heat-exchanger rig and makes the part group in waste gas Segregation junction；Remove bulky grain solid particles and the liquid elaioleucite condensing in waste gas through new removing oil cleaner again；Then pass through Boehmeria filter equipped with ramee pipe carries out finly filtration, to remove the trickle grit in removing exhaust gas further.This invention energy consumption Higher, equipment is more complicated.
Number of patent application is that the invention of 201510509707x belongs to industrial technical field of waste gas treatment, particularly to one Plant oil-containing waste gas recovery equipment and oil-containing gas recovery method.This kind of oil-containing waste gas recovery equipment, including fume collection device, valve Assembly, elastic oil suction filler, heating apparatuss and pressurizing unit, described valve member is used for controlling entrance and the flue gas of oil-contg. smoke With oily discharge, for absorbing the elaioleucite in oil-contg. smoke, described heating apparatuss are used for flue gas is received described elasticity oil suction filler Carrying out in storage heats makes the elaioleucite being adsorbed in elastic oil suction filler be changed into liquid phase, and described pressurizing unit is used for extruding elasticity Oil suction filler makes oil discharge from oil drain out.Above-mentioned oil-containing waste gas recovery equipment, structure is more complicated, and parts are more；Fault rate Higher.
Content of the invention
Goal of the invention: provide one kind to enable to waste oil in waste gas and separated and collected, do not affect purifier detergent power Oil-containing waste gas purifier.
Technical scheme:
Ultimate principle: the biological treatment device of waste gas or Biological Pretreatment device, it is required to circulation fluid or recirculated water, generally individually By water circulating pump, the circulation fluid in circulating box is promoted to the packing layer of pretreatment or biological treatment, thus to biological cycle Waste gas in liquid carries out absorbing decomposing to be realized purifying purpose.
The processing meanss of the oil-containing waste gas of the present invention, have biological cleaning processing meanss, water circulating pump, oil water separator, Contaminated oil pipe.
Biological cleaning processing meanss bottom has a cyclic water tank, biological cleaning processing meanss (built-in microbial treatments layer) or The side wall of person's cyclic water tank have oil-containing exhaust gas entrance (oil-containing waste gas oil-containing, vocs, carbon dioxide, nitrogen, steam, perhaps Also has dust, perhaps EGT is also very high, if temperature is high or dust is too high also needs to supporting corresponding treatment measures Deng), cyclic water tank side wall has mixture export (flowing out for waste water or containing waste water).The top tool of biological cleaning processing meanss Have and process later low concentration gas outlet；Side wall or top have separating liquid (or claim low concentration circulation fluid, or separate gas) Entrance, then separating liquid be sent to above microbial treatments layer；There are in tower the microbial treatments positioned at separating liquid entrance bottom Layer (wherein containing microorganism fungus kind).
Mixture export passes through water circulating pump UNICOM oil water separator, by oil water separator separation greasy dirt, oil-water separation Utensil has discharge channel and sump oil outlet, and the separating liquid of relative clean is sent to separating liquid (or separating gas) entrance.Sump oil Outlet connects contaminated oil pipe.Oil-water separation is realized by circulation fluid oily-water seperating equipment, relative clean does not contain after separating Or the recirculated water of low concentration oil-containing enters biological adsorption bed, be conducive to improving the effect of biological treatment.
Separating liquid entrance can be connected with the spray equipment above microbial treatments layer.
During work, oil-containing waste gas by oil-containing exhaust gas entrance enter biological cleaning processing meanss, wherein pass through filler and Water contact mixing, the material (including oil field oil and portion gas oil) in portion enters cyclic water tank.Then, with recirculated water Liquid in case forms mixed solution, is exported by mixed solution and flows out, under the pumping of water circulating pump, is admitted to oil-water separation Device.It is separated into greasy dirt and separating liquid in oil water separator, greasy dirt exits into contaminated oil pipe from sump oil outlet.In original water pump Under pumping pressure effect, separating liquid (or separating gas) flows out from discharge channel, enters at biological cleaning from separating liquid entrance In reason device, flow through (or contacting after being sprayed by spray equipment) microbial treatments layer.Organic principle in separating liquid is by micro- life Thing is decomposed or is absorbed, and remaining solution is cleaner, becomes purified solution, instills cyclic water tank.Gas by purification substantially Export emptying from clean gas, after clean gas outlet, biological treatment device can be reconnected.
After such continuous and local cycle operation, the greasy dirt that contains in waste gas is by constantly separately it is ensured that in waste gas Oil gas be most separated out.In waste gas, organic gas or toxic gas are decomposed by most of absorption, are formed after being cleaned Purification gas from clean gas export emptying.
Spray equipment can be joined directly together with discharge channel.Spray equipment can configure demister, to go Except part water smoke so that microbial treatments layer activity is more suitable.
Below spray equipment, in microbial treatments layer, can also have filler (pp microsphere or other granular material), Contribute to the organic gas such as voc to be dissolved in the water, be both easy to separate with clean gas such as nitrogen, carbon dioxide, be easy to organic again Gas is exported by clean gas and absorbs.
Beneficial effect:
The structure of the present invention is simple, and construction cost is low；The oil gas composition in waste gas can be reclaimed, turn waste into wealth, utilize former simultaneously There are lift and the oil water separator of circulating pump, reduce investment, save operating cost；Through circulation several times (suggestion made into several times: Separate) after, it is substantially clean that greasy dirt separates removing.In waste gas, harmful components are recycled in oily form, partly by biologic packing material Decompose, little harmful components in the gas of emptying, harmless components emptying is not take up storing utensil.Microbial treatments low cost, micro- Biological survival regeneration is easily controlled.Whole processing procedure environmental protection, does not have the consumption of other raw materials or the energy.
