Description
Technical field
The utility model relates to a kind of Sludge in Oilfields processing equipment for recycling.
Background technology
The source of oil sludge mainly is the sandy oil-containing sludge that produces in the Oil extraction process, the sandy oil-containing sludge that contains sandy oil-containing sludge and the generation of refinery's Sewage treatment systems of oil field gathering and transportation process generation.These oil sludges also contain the stratum silt that carries in the Produced Liquid except containing crude oil, the flco that forms in the sewage treatment process of disposing polluted water in oil station, corrosive pipeline product, heavy metal salt and paraffin, gum asphalt etc., and certain moisture content.
The oily sludge that produces in the Oil extraction process is mainly derived from Ground Processing System, and the oily sludge that produces in the oil extraction-generated waste water treating processes is added flco that the water purification agent that adds in the dirty water decontamination handles forms etc. and formed oily sludge.
The oil field gathering and transportation process produces oil tank that oily sludge is mainly derived from block station, joint station, slurry tank, Water Tank, oil trap bed mud, oil product storage tank when storing oil product, a small amount of mechanical impurity in the oil product, the grains of sand, earth, heavy metal salt and the heavy components such as paraffin and bituminous matter are deposited on tank bottom, form tank bottom oil sludge.The blowdown of slurry tank, secondary settlement tank, well-flushing water withdrawing can also can produce oily sludge in addition.
By analysis these oily sludges form different, usually oil length between 10%~60%, the solids 10-60% such as silt, and water 15-60%.In the situation that petroleum resources growing tension and environmental problem are on the rise, the crude oil in the efficient recovery oil sludge has not only been saved valuable petroleum resources, and has eliminated environmental pollution.
Relatively the method for processing oily sludge commonly used has at present: solidify and bury, burn hot washing method, solvent extration, chemical demulsification method, solid-liquid isolation method, pyrolysis method etc.But wherein many methods all exist some problems, are not suitable for very much for practical application.Power consumption greatly, easily produces secondary pollution such as burning method, the crude resources waste; Biological treatment need last length, and same crude resources also can not get recycling; Chemical demulsification method need add emulsion splitter and heating in addition to the serious oily sludge of emulsification, and aftertreatment is difficult, also produces secondary pollution simultaneously; Solid-liquid isolation method is low for the crude oil recovery rate that contains innage, with serious pollution oily sludge; The pyrolysis method facility investment is high.
Solvent extraction is the effective ways that reclaim crude oil, and the body refuse after the extraction more easily reaches the national standard of landfill or stacking, but and the crude resources of efficient recovery preciousness, thereby draw its people's concern.Patent CN1526797A uses extraction process and reclaim oil fuel from oily sludge, and this patent adopts general extraction tower, and when the oily sludge layering was slower, the diluted acid that needs to add 1-3% carried out breakdown of emulsion, can cause the corrosion of equipment and the secondary pollution of environment.
The utility model content
The purpose of this utility model provides a kind of Sludge in Oilfields processing equipment for recycling, oily sludge is after extraction, sedimentation, separation, fractionation, crude oil is recycled, the solvent reclamation reuse, and solid slag can reach the GB4284-84 effluent standard after biological degradation is processed.
Sludge in Oilfields processing equipment for recycling described in the utility model comprises lift, vetivert rotary screen, many oars of single armed extraction equipment, separate and subside tank, two phase separation pot, stream curtain formula extraction tower, electro-flotation system, vacuum still, sludge sump, biological degradation system, solvent makeup tank and crude oil finished pot; Lift is positioned at the sludge sump top, is connected with vetivert rotary screen, and the outlet that vetivert rotary screen is positioned at the bottom is connected with the entrance of many oars of single armed extraction equipment; The outlet of many oars of single armed extraction equipment is connected with the separate and subside tank; The solid phase outlet of separate and subside tank is connected with the entrance of stream curtain formula extraction tower; The liquid-phase outlet of separate and subside tank is connected with two phase separation pot; The oil phase outlet of two phase separation pot is connected with the vacuum still entrance, and the water outlet of two phase separation pot is connected with the electro-flotation system; The outlet of vacuum still extraction agent is connected with the solvent makeup tank, and the vacuum still crude exports are connected with the crude oil finished pot, and the solvent makeup tank is connected with the extraction agent entrance that is connected curtain formula extraction tower with many oars of single armed extraction equipment; The oily(waste)water outlet of sludge sump is connected with the electro-flotation system, and the dregs of fat outlet of electro-flotation system is connected with the entrance of stream curtain formula extraction tower; The water outlet of electro-flotation system is connected with water treatment system, and the solid phase outlet of stream curtain formula extraction tower is connected with the biological degradation system.
Sludge in Oilfields processing equipment for recycling described in the utility model:
One cover sludge pretreatment equipment, its core is vetivert rotary screen, is contained in ratchel and foreign material in the mud by this equipment rough segmentation.
One cover single armed many oars extraction equipment, its core is the many oars of single armed and extraction agent, the shear agitation effect by the many oars of single armed and extraction agent makes silt, crude oil solvent mixture and sewage three-phase settlement separate.It is equipped with settlement separation tank, solvent makeup tank and robot control system(RCS).
One cover is processed the stream curtain formula extraction equipment of shale oily sludge, the shale oily sludge is after many oars of single armed extracting system separates, because the close greasy filth of proportion and crude oil can't pass through gravity separation, only have by behind stream curtain formula extracting system and the extraction agent mixing, washing, make mud up to standard.
One cover crude separation, solvent reclaiming equipment, nucleus equipment is vacuum still, since from crude oil and extractant mixture after shale and chiltern separate, must valuable crude resources be separated with valuable extraction agent by vacuum distillation technique, crude oil is defeated outward as finished product.Solvent cycle is usefulness again, reduces running cost.Auxiliary facility has the integrated heating of solvent makeup tank, crude oil finished pot and distillation tower, cools off, vacuumizes facility and robot control system(RCS).Do not select the air distillation reason to have two: one so only select underpressure distillation, reduce the light constituent quantity of distillate that cut point reduces energy consumption, reduces crude oil; The 2nd, reduce the loss of solvent.
With the auxiliary material that contains biological inoculum with process after waste residue admix certain hour in proportion after, this waste residue is innoxious to reach national agricultural emission standard.
Sludge in Oilfields processing equipment for recycling described in the utility model.Silt particle oil-containing after this device is processed reach national stacking standard (<3000mg/kg).
