Description
Technical field
The invention belongs to technical field of grease processing, relate in particular to a kind of grease recovery method.
Background technology
At present, the pollution that grease caused has caused the great problem of modern society, and it not only impacts the human life quality, and its harm to natural, ecological is very huge.In the surging modern society of environmental consciousness, how to seek to such an extent that a special kind of skill reclaims with the grease with contaminate environment, real is the task of top priority.
For example, for fry in shallow oil, boil, fry, fried and profit that the surplus treating processes in kitchen is produced, or the oil wastewater that produced of washing pot dish tableware, the profit cognition that people are main, all the time it is lighter to rest on grease proportion, adopts gravity principle to separate the stereotype that grease can be effective.Yet segmentation grease institute's deutero-form in discharge process can be divided into six kinds at least:
1. floating oiling: this is the most simple grease, normally the fastest polymeric grease form in the cooking or the washing water.
2. gel oil: mixed animality gelatine or thicken soup in the grease, presented glutinous greasy but be difficult for characteristic on floating.
3. condensation of oil: grease is higher because of low temperature in the water and animal raw fat ratio, and gives birth to the phenomenon of condensing.
4. winterized stearin: residue in the condensation of oil polywater partly presents the sclerosis oil clot through sanitising agent effect and atmospheric oxidation.
5. suspension oil: tiny oil droplets combines with suspended particle, because of proportion is close in water, scurries with current, and is not easily separated.
6. oil in water emulsion: the complete emulsification of the false emulsification that high temperature produces and sanitising agent fusion belongs to the most difficult isolating grease.
Therefore handle quality if desire to reach ideal, must be researched and analysed, prevented and treated at the waste water of kitchen discharge water at the grease of various different attributes.Yet general oily water separation technique is not considered the problem that the different shape grease is produced, and makes the suitability of product fail all the time to improve, and must be dependent on the maintaining of large quantities of manpowers, to guarantee to handle quality.It is as follows that traditional oily water separation mode can be concluded disappearance:
(1) tradition is cut oil groove: stopping residue to carry cage, and hold back grease with dividing plate, so is that residue or grease all must be with artificially collecting, if fail in time to remove, residue and grease all can continue to enter the back depot siding with sewage, cause obstruction.The grease that is detained causes to silt up with health and worsens even lump.
(2) steel band Oil scraper: utilize principles oily and the different coefficient of viscosities of water, allow grease attach on steel band and dispel, so only for general floating grease and the part gel oil gone up, majority easily condenses and the hardened grease, because coefficient of viscosity changes, steel band can't attach, and will amass to cause in groove and silt up.
(3) reciprocal scraper plate machine: the grease that utilizes scraper plate to float is brought another into and is collected cell body, so because of grease solidifies easily, easily lumps in another collects cell body on the contrary, causes the puzzlement in the collection.
(4) biological decomposition method: the biological decomposition method is for fear of the generation of digestion rate far away from the kitchen pollution thing, present utilization still is limited to pipeline maintenance and environmental health, follow-uply be provided with the person of sewage work, more must be careful biological inoculum existing ecological generation of active sludge impacted.
On the other hand, cause in the pollution of the sea factor at all, the most serious with petroleum pollution again.
And the petroleum pollution form is mainly as follows:
(a) the regular omission of ship:
(b) particularly betide near the harbour,, often be coated with oil slick or the similar colloid of black on the sea, must use and block wick and oil suction equipment is regularly removed because the intensive discrepancy of ship is stopped.
(c) waste material:
From land metropolitan area and manufacturing district waste, chemical substance or technical oils.The pollution of this class may be via the rivers and creeks transmission, even causes land face river pollution.Must in moment takes place in pollution incident, use and block wick control oil slick, be removed elimination, cause pollution for the second time in case the ocean is gone in fluid stopping.
(d) oil tanker unscheduled event:
When the oil tanker unscheduled event took place, substantial oil was excessive fast, must be in the shortest time take place in incident, and use and block wick and surround oil slick, the expansion of control oil slick, this will be enough to determine after a while and the oil slick disposal costs of coming and damage is dropped to minimum.
Other is surveyed as atmospheric pollution offshore oil brill and natural gas circulation also might cause pollution of the sea.
Though the crude oil major part in the pollution of the sea is all removed, but residue in the oil stain and the greasy dirt of seabeach or crag,, can't get food or utilization for Institute of Micro-biology in general nature circle or the soil owing to can't be dissolved by water molecules, promptly can't produce biological degradation, cause the great calamity of coastal whole ecological.
Therefore, in order to promote melting mutually alternately of grease and water molecules, prior art provides the application of interfacial agent (surfactant).Yet the present interfaces promoting agent all is chemical interface promoting agent, to environmental ecology often toxic (for example negatively charged ion interface promoting agent); Though or itself low toxicity, its metabolic derivative be harmful (for example the nonyl phenol polyethoxye alcohol (NPEOS) of nonionic interface promoting agent though the class low toxicity, its derivative nonylphenol has the Environmental Hormone effect).Therefore, biological in recent years interface promoting agent (biosurfactant) and bioelectric interface emulsifying agent (bioemulsifier) widely are applied to the field of petroleum pollution.
According to the definition of Banat (1995), biological interface promoting agent is the heterogeneous interface sensitization of a group molecule that Institute of Micro-biology produces, and this molecule can reduce liquor and hydrocarbon polymer blended surface tension, micelle threshold concentration and interfacial tension.In the micelle production process, can make solution pass through microemulsion, make hydrocarbon polymer soluble in water, or make water-solublely in hydrocarbon polymer, make greasy dirt be easy to remove, easier is environmental microorganism institute digest and decompose.In addition, often accumulate many heavy metals and mud at the bottom of the oil storage tank, annual must regularly the removing.It is many with chemical interface promoting agent to remove operation in the past, often causes danger, consuming time, consumption power, consumes money.Banat etc. (1991) replace with the bioelectric interface promoting agent, no matter it is an oil in the water, or W/O, biological interface promoting agent can form big emulsification and microemulsion, reduces the stickiness of mud, extracts with convenient group Pu, and profit is more easily isolated fractionation after emulsifying effect.But no matter be chemical interface promoting agent or bioelectric interface promoting agent, it is grease emulsifying is beneficial to remove, yet behind the grease emulsifying, and can't recycle once again, so it only reaches " remove greasy dirt " effect, very waste.And it is very huge to use chemical interface promoting agent or biological interface promoting agent to remove the cost that greasy dirt spent.
And aspect oil production, because of oil has gaseous state, liquid state and bitum solid-state, so it is deposited in the rock gap of upper crustal, the complexity that varies in size when exploiting in space is just different, if there is not the oil in the external pressure space to be difficult to overflow next.There are many oil wells in each oil field, all needs to carry out three different modes the oil extraction is come out.The pressure that for the first time is stratum itself up gushes oil oneself, and pressure pump is established again to the stratum oil recovery of exerting pressure in the outside, can adopt 30 percent like this.Recover the oil for the second time is because oil extraction after some, reservoir pressure is not enough, oil pick-up tube can't touch oil, so exploitation person orders about oil flow to ground from past underground a large amount of water fillings of the other end of oil well and aeration, can extract 10 to 20 oil like this.Tertiary process then is cemented in the rock seam owing to sticky because of remaining in rock spatial oil, extremely difficult exploitation, and current mode is recovered the oil by force for the third time for the biochemical bacterium method of injection.Yet because of leased land, set up oil recovery refining equipment, building highway or railway, and the manpower consumption all is huge expenditures, so the process of oil production each time, the cost of cost is all very high.Moreover exploitation action each time all may cause consumption of petroleum, and this also is a cost burden concerning oil production.
