Description
Technical field
The present invention relates to the processing system and its processing method of a kind of oily sludge.
Background technology
Greasy filth is primarily referred to as the oily sludge of the formation such as the crude oil caused due to a variety of causes or other oil products and soil, with
And the oily sediment that system is taken out of in the normal production in oil field etc., it is a kind of solid waste rich in mineral oil, main component is former
Oil, Ni Heshui.Solid particle size can be from not enough micron to several inches, and the composition of oil depends on crude oil species, oil plant structure
With operating condition, the composition of sludge may change over time and change.Contain certain crude oil, heavy metal ion in usual sludge
（Such as iron, copper, nickel）With inorganic salts compound etc..The materials such as benzene homologues, phenols are typically contained in these greasy filth, and with evil
Smelly and toxicity, if directly being contacted with natural environment, can make soil poison, be acidified or alkalize, and cause changing for soil and soil structure
Become, hinder plant root growth and larger pollution can be caused to water body and vegetation, while also implying that the waste of petroleum resources.
Oily sludge belongs to heterogeneous system, typically by oil-in-water（O/W）, Water-In-Oil（W/O）With suspended solid composition, dirt
Suspended solid, colloidal solid in mud is fully emulsified with oil, water, forms the suspension emulsion system of stabilization, and viscosity is larger, it is difficult to
Sedimentation.With complicated component, water content is high, volume is big, harmful components it is most more than discharge standard, contain calorific value higher, comprehensive
Close the characteristics such as Land use systems are few, intractability is big.
By China Hazardous Waste List, greasy filth is put into《National Hazard waste catalogue》In oily waste water species (HW08
).Its chronicity and potentiality to environmental hazard, just attracts great attention.Carrying out greasy filth management and Study of Prevention Technology is
One vital task of current national environmental protection work.Therefore, how these oily sludges are carried out innoxious and recycling,
It is also a pendulum important environmental issue urgently to be resolved hurrily in face of oil refining industry.
The treatment technology of the solid waste such as current oily sludge, mainly there is burning method, biological degradation method, solvent extraction
Method, quenched-mechanical phonograph recorder separation, concentration desiccation method, microwave treatment method etc., the weak point of these methods may be summarized to be two classes：
One class such as burning method and biological degradation method, put forth effort on control pollutant emission, have ignored the recycling of oil product resource；It is another kind of
Such as solvent extraction, quenched-mechanical phonograph recorder separation, hot wash method, pyrolysismethod, oil product resource can be reclaimed, but be difficult to control to waste water, waste residue
Secondary pollution to environment, these methods cannot all obtain balance between environment and benefit.
For example, solvent extraction is according to " similar compatibility " principle, suitable organic solvent is chosen come in extracting greasy filth
Organic matter, is then recovered by distillation the oil in extract again, solvent is separated from mixture circulation by distillation
Use.The advantage of the method is process is simple, and extractant can be reused, and have the disadvantage that extractant is expensive, is recycled
During there are a large amount of solvent losses, through the greasy filth oil content after treatment be more than 5% or so, do not reach existing solid pollutant
Discharge standard.
Quenched-organizational separation method：Because oily sludge is typically all the suspension emulsion system of stabilization, so before dehydration
Oily sludge is carried out quenched.Quenched method is in addition to dosing coagulant, flocculation aid, it is necessary to adds surfactant, break
Emulsion, pH adjusting agent etc., while being aided with the reinforcing means such as heating, to improve sludge physical property, change the proterties of oily sludge particle
And ordered state, destroy the stability of colloid, so as to improve the dewatering of sludge, then using three-phase centrifuge to treatment after
Sludge carry out oil, water, mud three phase separation, with simple to operate, technology it is more ripe, practicality is good the features such as, it is recyclable big
Part oil.But its core technology is ultracentrifugal three-phase separating device, monopolized by the country such as America and Europe substantially, China is also difficult to
Production such device.The shortcoming of quenched-isolation technics：Due to oily sludge species a lot, existing dewatering machine equipment and medicament
Combination can't generally be applicable.Therefore, the research to quenched-mechanical separation technology is limited only to single or a small number of greasy filth samples
Product, poor universality, and, it is necessary to redefine coagulant during using different oily sludges（Species, dosage and dosing side
Formula）, demulsifier（Species, dosage and dosing method）, dewatering machine model and operational factor.Furthermore, when oil sludge contains
When oil mass is less, centrifugation economic benefit is not good.Because the solids content in centrifuge is higher and Treatment of Sludge can be influenceed to imitate
Really, oil-sludge treatment amount in this way it is relatively low, it is impossible to meet the requirement of existing extensive treatment.
Chemico-heating wash method：Cyclic washing is carried out to oily sludge by hydrothermal solution, is added in washing process efficiently, suitably
Chemical agent, then it is heated, mix after staticly settle, realize separation of solid and liquid.The oil phase isolated enters after treatment
Oil storage tank, the recyclable utilization of cleaning fluid, remaining sludge then carries out recycling after dehydration reprocessing.The sieve of chemical reagent
Choosing and using the key for being chemico-heating wash technique, in heating, the separation process of stirring, be mainly concerned with reduction interfacial tension,
Emulsification, the change principle such as wetability and rigid interface film.But the method is only applicable to, and oil content is higher, emulsify lighter to fall
The crude oil recovery treatment of ground crude oil and oil-sand, it is difficult to which the serious greasy filth for the treatment of emulsification is not applied to but；Need to add substantial amounts of cost
Expensive chemical agent, causes high cost；Oil-containing is higher in residue after treatment, and the sludge residue water content after separation is more than
90% and containing substantial amounts of chemical agent, can also cause the secondary pollution such as waste water, waste residue problem, it is necessary to further treatment is utilized.
Also, although the method such as above-mentioned solvent extraction, quenched-mechanical phonograph recorder separation, chemico-heating wash method can reclaim sludge
In oil product resource, but because the debris in oily sludge are more, including ratchel, wood, metal object, plastics thing, woven bag
Deng, being generally required in removal process first to raw material sieve etc. pretreatment, debris in removal raw material, then just with medicament one
Play mixed processing；And because oily sludge viscosity is larger, debris are mutually bonded with soil, pretreatment is difficult to go removal of impurities completely
Thing, remaining debris can seriously hinder equipment and facility normally to run.
