Description
Technical field
The present invention relates to Waste Disposal Technology fields, and in particular to a kind of oily sludge disposal system and its disposition work
Skill.
Background technique
Oily sludge is the oily solid sludge of generation during oil exploitation, transport, refining and oily waste water treatment, is
One of main polluting waste generated in oil and gas development and storage and transport process.In oily sludge containing a large amount of benzene homologues, phenols,
The noxious material of the foul smellings such as anthracene, pyrene, but these substances are also oil component simultaneously.Oily sludge is both in oilfield process
The waste of generation, while being also a kind of resource, if oily sludge is not pocessed recycling oil therein, not only pollute ring
Border, and cause the waste of resource.The processing of oily sludge is always a great problem in oil field.For many years, China oil field
The essentially discarded oil pit landfill of the greasy filth disposal options in area, this kind of nonstandard discarded and disposal process are brought very to environment
Big pollution hidden trouble.Harmless treatment and Oil residue recuperation are carried out to oily sludge using suitable technological means, can not only be generated
Certain economic benefit, and meeting pollution abatement, bring huge environmental benefit and social benefit.
Method of disposal common for oily sludge includes solvent extraction, incineration method, bioanalysis, indirect thermal phase point at present
From method etc..
1, the process object of incineration method, burning is mainly greasy filth of the oil content 5~10%, and incineration temperature general control exists
800~1000 DEG C, time control is burned in 0.5~1.5h, using 50~100% excess airs.China part oil plant has
Sludge incineration device, the downflow type rotary incinerator used such as Hubei Jingmen petrochemical plant, Chang Ling petrochemical plant, Yanshan Petrochemical use
Fluidized bed incinerator, etc..After burning disposal, multiple harmful substances almost all removes oily sludge, works well.But
It invests big, and operating cost is high, need to often be added combustion-supporting fuel, with serious air pollution in burning process, and cannot return
Crude oil is received, the soil after burning is not suitable for planting.
2, solvent extraction, solvent extraction are a kind of for handling the technology of the small oily sludge of the more particles of silt.
The technology utilization extractant dissolves oily sludge, and after agitated and centrifugation, most of organic matter and oil are extracted agent from mud
It extracts；Then recycling extract liquor, which is distilled, is separated from the mixture solvent to be recycled, and oil is used after mutually recycling
In refining again.Solvent extraction generally carries out at room temperature, and solvent is better than bigger effect of extracting, but solvent is than big extraction equipment
The load becomes large, and energy consumption is relatively large.Largely fail the related request for reaching country by sludge extracted, still contains
Higher oil remains a kind of hazardous waste, need to further dispose.Since cost of disposal is high and technique need to be further complete
Kind, extraction is applied to refinery's disposal of oily sludge not yet.
3, bioanalysis, microbial degradation are degraded using original or microbe inoculation (i.e. other microorganisms of fungi, bacterium)
(metabolism) pollutant in soil, and convert pollutant to the process of harmless end prod.The technology to the consumption of energy compared with
It is low, can be with the biggish contaminated site of repaired area, but be affected by environmental factor, cannot degrade all dirts into environment
Object is contaminated, specified microorganisms are only degraded specific pollutants.Process is slow at low temperature for biodegrade, and repair time is long, it usually needs
Several years.The shadow of many factors such as the contaminated physical property matter of biological prosthetic remediation efficiency, Ecological Distribution of Soil Microorganisms structure, soil property
It rings, and more demanding to the nutritional condition in soil.If soil media contaminant restraining microorganism, possibly mesh can not be removed
Mark.The temperature, pH value, nutrient amount etc. for needing to control place are allowed to meet the survival environmental conditions of microorganism.Due to many
The limitation of condition, bioanalysis are not applied to refinery's disposal of oily sludge yet.
4, indirect thermal phase separation method, indirect thermal phase separation method refer to that one kind by indirect heating oily sludge, is separated and simultaneously returned
The method for receiving oily phase.Indirect thermal phase detachment technique passes through heat transfer using the extraneous high-temperature flue gas heating pyrolysis cavity generated
Mode indirect heating oily sludge, its moisture and oil are evaporated, and are introduced condenser and are carried out spray condensation and water-oil separating,
It is finally reached the purpose of oil recovery phase.The technology has many advantages, such as that technical process is simple, disposition effect is good.But indirect heat transmission
Heat transfer efficiency is very low, and disposal of oily sludge amount is not high, and currently used indirect thermal device for phase saparation monomer treating capacity only has 1~2
Ton/hour, affect the large-scale application of technique.Indirect thermal phase detachment technique is very high to the material requirements of pyrolysis cavity,
There should be good heat transfer efficiency to guarantee that grease sufficiently evaporates, there is good shell rigidity to guarantee the smooth operation of material again.It is right
For material, the two attributes are a paradox, at present still without extraordinary solution, to affect technique
Further genralrlization.
In conclusion currently used oily sludge method of disposal all has some limitations, incineration method cannot be recycled
Crude oil, and the soil after burning is not suitable for planting；Solvent extraction cost of disposal is high, and soil extracted is many times
It does not reach requirement；Bioanalysis is affected by environmental factor, and repair time is long；Indirect thermal phase separation method is then since heat transfer is imitated
The problem of rate and material property, affects the large-scale application and popularization of the technology.
