Abstract
The invention discloses a treating system, separating apparatus and treating method for oily sludge. The separating apparatus comprises a stirring drum, a first drive unit, a stirring shaft, multiple layers of separator plates and stirring members, wherein the stirring shaft is arranged in the stirring drum; the multiple layers of separator plates divide the stirring drum into multiple layers of space; each of the multiple layers of space is provided with one stirring member which is connected with the stirring shaft; the upper part of the stirring drum is provided with a sludge inlet and first floating oil discharge outlet; the lower part of the stirring drum is provided with a sludge outlet; and the bottom or lower part of the stirring drum is provided with a feed inlet for one or more selected from a group consisting of an extractant, air-dissolved water and solid foam particles. The treating system is applicable to dehydration of a variety of oily sludge, enables the oil content of oily sludge to be decreased to 3% or below, can maximally recover oil and does not produce secondary pollution like waste water.
Description
Technical field
The present invention relates to processing system and its separation equipment, the 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 and change.Generally contain certain crude oil, heavy metal ion in 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 contacting 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 stable suspension emulsion system, and viscosity is larger, it is difficult to
Sedimentation.With complicated component, water content is high, volume is big, harmful components are most more than discharge standard, containing higher calorific value, 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 national environmental protection work at present.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.
At present the treatment technology of the solid waste such as oily sludge, mainly there is burning method, biological degradation method, solvent extraction
Method, quenched-mechanical phonograph recorder separation, concentration mummification 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 all cannot obtain balance between environment and benefit.
For example, solvent extraction is according to " similar compatibility " principle, in choosing suitable organic solvent to extract greasy filth
Organic matter, the oil being then recovered by distillation again in extract separates circulation solvent by distillation from mixture
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, Jing process after greasy filth oil content be more than 5% or so, do not reach existing solid pollutant
Discharge standard.
Quenched-organizational separation method：Because oily sludge is typically all stable suspension emulsion system, 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 colloid stability, so as to improve the dewatering of sludge, then using three-phase centrifuge to process 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 suitable for.Therefore, single or minority greasy filth sample is limited only to the research of quenched-mechanical separation technology
Product, poor universality, and during using different oily sludges, need to redefine coagulant（Species, dosage and plus prescription

When measuring less, centrifugation economic benefit is not good.Because the solids content in centrifuge is higher and can affect Treatment of Sludge effect,
Oil-sludge treatment amount in this way it is relatively low, it is impossible to meet the requirement of existing extensive process.
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 is entered Jing after processing
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 of ground crude oil and oil-sand is processed, it is difficult to is processed the serious greasy filth of emulsification and is not but applied to；Need to add substantial amounts of cost
Expensive chemical agent, causes high cost；Oil-containing is higher in residue after process, 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 problem such as waste water, waste residue, need further to process and utilize.
The content of the invention
