Description

The processing system and its disintegrating apparatus of a kind of oily sludge
Technical field
It the utility model is related to the processing system and its disintegrating apparatus of a kind of oily sludge.
Background technology
Greasy filth is primarily referred to as the oily sludge due to crude oil caused by a variety of causes or the formation such as other oil products and soil, with And 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 insufficient micron to several inches, and oily composition depends on crude oil species, oil plant structure With operating condition, the composition of sludge may be changed over time and changed.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, soil can be made to poison, be acidified or alkalize, 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 imply that the waste of petroleum resources.
Oily sludge belongs to heterogeneous system, typically by oil-in-water(O/W), Water-In-Oil(W/O)Formed with suspended solid, it is dirty Suspended solid, colloidal solid and oil, water in mud is fully emulsified, forms stable suspension emulsion system, viscosity is larger, it is difficult to Sedimentation.With complicated component, water content is high, volume is big, harmful components are most exceedes discharge standard, contains 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 carry out innoxious and recycling, And the important environmental issue that pendulum is urgently to be resolved hurrily in face of oil refining industry.
The treatment technology of the solid waste such as oily sludge at present, 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: A kind of 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, is but difficult to control waste water, waste residue Secondary pollution to environment, these methods can not all obtain balance between environment and benefit.
For example, solvent extraction is according to " similar compatibility " principle, suitable organic solvent is chosen to extract in greasy filth Organic matter, the oil in extract is then recovered by distillation again, circulation separates solvent from mixture by distillation Use.The advantages of this method is that technique is simple, and extractant may be reused, and shortcoming is that extractant is expensive, is recycled During there are a large amount of solvent losses, the greasy filth oil content after processing 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, breaks Emulsion, pH adjusting agent etc., while it is aided with the reinforcing means such as heating, to improve sludge physical property, change the character 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 processing after Sludge carry out oil, water, mud three phase separation, have the characteristics that simple to operate, technology more maturation, practicality it is good, it is recyclable greatly Part oil.But its core technology is ultracentrifugal three-phase separating device, monopolized substantially by the country such as America and Europe, China is also difficult to Produce such device.The shortcomings that quenched-isolation technics:Because oily sludge species is 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 the different oily sludge of use(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, it is bad to centrifuge economic benefit.Treatment of Sludge effect can be influenceed because the solids content in centrifuge is higher Fruit, oil-sludge treatment amount in this way it is relatively low, it is impossible to meet the existing requirement handled on a large scale.
Chemico-heating wash method:Oily sludge is washed repeatedly by hydrothermal solution, 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 processing Oil storage tank, the recyclable utilization of cleaning fluid, remaining sludge then carry out recycling after dehydration reprocessing.The sieve of chemical reagent Choosing and using be chemico-heating wash technique key, heating, stirring separation process in, be mainly concerned with reduce interfacial tension, Emulsification, change the principle such as wetability and rigid interface film.But this method is only applicable to, and oil content is higher, emulsification lighter falls The crude oil recovery of ground crude oil and oil-sand processing, it is difficult to which processing emulsifies serious greasy filth and do not applied to but;Need to add substantial amounts of cost Expensive chemical agent, causes cost height;Oil-containing is higher in residue after processing, and the sludge residue water content after separation is more than 90% and contain substantial amounts of chemical agent, can also cause the secondary pollution such as waste water, waste residue problem, it is necessary to which further processing utilizes.
Further, although sludge can be reclaimed the methods of above-mentioned solvent extraction, quenched-mechanical phonograph recorder separation, chemico-heating wash method In oil product resource, but because the debris in oily sludge is more, including ratchel, wood, metal object, plastics thing, woven bag Deng, generally required in removal process and first to raw material sieve etc. pretreatment, remove debris in raw material, then just with medicament one Play mixed processing;And because oily sludge viscosity is larger, debris is mutually bonded with soil, pretreatment is difficult to go to clean completely Thing, remaining debris can seriously hinder equipment and facility normal operation.
