Description
Technical field
The invention belongs to contained Mud Treatment Technology fields, and in particular to a kind of oil sludge processing equipment and technique.
Background technique
Oil sludge is the major pollutants generated in oil exploitation, transport and storage and transport process, wherein the oil-containing in oil plant
Sludge mainly from " three mud ", including generated when sewage from oil refinery processing oil separator bed mud, air-flotation process when the flotation that generates
Residual active sludge in pond dross and aerobic treatment.The characteristics of oil plant oily sludge is that water content is big, and component is multiple
It is miscellaneous, impurity is more, processing difficulty is big.Usually used by oil-in-water, Water-In-Oil and solid suspension and in process of production
The stable emulsion liquid system of various inorganic agent compositions, separating difficulty are very high.
The processing method of domestic and international oil sludge mainly has solidification method, incineration method, hot water washing, solvent extraction, ultrasound
Wave method, pyrolysis method, bioanalysis etc..
Wherein hot water washing is the processing method for being mainly used in ground sludge at present, mainly passes through thermokalite water or adds
Active dose of hot water repeatedly washs greasy filth.Its advantage is that easy to operate, applicability is wide, and cost is relatively low, the disadvantage is that
Secondary pollution is be easy to cause in treatment process, and separation degree is not especially high.
Incineration method is a kind of processing method that technology is more mature, and greasy filth burns in special incinerator, thoroughly sloughs it
In oil-containing organic matter.Its advantage is that easy to operate, processing speed is fast, can completely remove harmful substance in greasy filth, and burn
Generated thermal energy can recycle.The disadvantage is that the crude resources in greasy filth can be lost, and the energy consumption needed is larger, burning is released
Gas be likely to result in secondary pollution.

And recycling for extractant is realized by distillation technique.The advantages of solvent extraction is that greasy filth separation is thorough, and de-oiling rate is high, former
Oily resource can be utilized effectively, the disadvantage is that required Solvent quantity is larger, higher cost.
Solidification method is to utilize either physically or chemically to mix greasy filth with inert base, thus by the harmful substance in greasy filth
Coalescence is in solids.Its advantage is that can block by the poisonous and harmful substance in crude oil, avoid causing damages to environment, handle
It is at low cost, the disadvantage is that the crude resources in greasy filth can be lost, and need to add a large amount of substrates.
Pyrolysis method is divided into high-temperature decomposition and low-temperature treatment method, and greasy filth is heated to hydrocarbon cracking in the environment of anaerobic
Temperature, and by condensation, recycle hydrocarbons.Pyrolysis method processing speed is fast, and separating effect is obvious, the recyclable benefit of some hydrocarbon
With reducing resource waste, the disadvantage is that higher cost, operate more complex.
The effects of supercritical ultrasonics technology is the mechanical oscillation using ultrasonic wave reduces the viscosity of greasy filth Crude Oil, makees its adherency
With being remarkably decreased, to make oil, mud and water separation.Useful supercritical ultrasonics technology handles the report of oil sludge both at home and abroad at present, but uses
Supercritical ultrasonics technology handle oil plant oily sludge, there is also some difficulties, especially oil plant oily sludge be usually by oil-in-water,
The stable emulsion liquid system of Water-In-Oil and solid suspension and the various inorganic agents used in process of production composition, separation are difficult
It spends very high.

Isolated processing mode, due to the gap of granularity and density, passes through centrifugation after the application is demulsified under the effect of ultrasonic wave affector
Effect first separates oil from solid water (mixture of solid and water), then carries out solid water separation, and by water, from mud, (solid is useless
Object) in separate.
2, by increasing oil sludge pretreatment system, oil sludge is first subjected to demulsification circular treatment, is conducive to oil sludge
Abundant demulsification, be also beneficial to the subsequent continuous separating treatment to oil sludge.
3, increase primary centrifuge machine, convenient for the bulky grain solid object in oil sludge is first removed, be conducive to mitigate high speed from
Damage of the bulky grain solid to supercentrifuge when scheming first separates oil from oil water mixture is also beneficial to avoid big
Blocking of the granular solids to pipeline.
4, it deposits in oil sludge storage tank by pretreated oil sludge, convey in the duct, and in primary centrifuge machine
In while isolate bulky grain solid object, emulsified again there are also a small amount of solid small particles object.For this purpose, in supercentrifuge
Ultrasonic wave is set before import and acts on device assembly one, is pumped into height again after secondary demulsification being carried out from the oil sludge that primary centrifuge machine is discharged
Fast centrifuge is conducive to supercentrifuge and separates oil from oil sludge, and this separation is more adequately oily recycling
Rate is high.
5, it is provided with vibrating screen between low speed centrifuge and waste water tank, remains in when can filter low speed centrifuge separation
A small amount of dross in water layer, and can rupture when flocculant is mixed with muddy water layer and a large amount of froth bubbles occur, avoid bubble from depositing
There is situations such as overflow, improving the quality of recycling waste water, is reducing particle content in water.
6, by oil after separating in oil sludge, a small amount of flocculant is added in solid water mixture, it is easy to will be tiny
Dross particles reunite, increase granularity, so that readily solid water mixture be separated by low speed centrifuge；And due to
The road " oil " Yi Qian is separated, even if a small amount of flocculant is added in solid water mixture, solid water will not be caused to mix
The emulsification again of object.
7, second pipe static state is increased separately in ultrasonic wave effect device assembly two, primary centrifuge machine, supercentrifuge front end
Mixer, the 4th pipeline static mixer, third pipeline static mixer, so that oil sludge is transported according to itself during transportation
The power sent mixes more evenly in pipeline static mixer, be conducive to demulsification, separation more sufficiently, improve oil removing, desilt
Processing quality and treatment effeciency.
8, the waste water circulatory system is increased, i.e., increases water return pipeline in waste water tank, and export in boiler and increase cleaning
Pipeline, the water in system can recycle, and are conducive to protect environment, reduce cost；The vibrating screen being arranged before waste water tank simultaneously,
Remaining dross content in waste water is further decreased, corrosion of the waste water to pipeline is reduced, extends making for the oil sludge processing equipment
Use the service life.
9, by the way that at least one oil sludge storage tank is arranged, one oil sludge storage tank of every increase is equivalent to and increases a set of sump oil
Mud processing equipment, it is cover while using more, improve the treatment effeciency of oil sludge.
