Field sewage network；
(4) greasy filth agitator tank 8 is stainless steel material, selects greasy filth agitator tank 8 that need to do obturator, prevents waving for extractant
Hair, greasy filth agitator tank 8 are mainly made of stirring tank body, stirring cover, blender, bearing, transmission device, gland seal device etc., if
Two imports, an outlet are set, convenient for the charging of mud and solvent and the discharging of extract liquor.Equipped with agitating device, heating and heat-insulating device,
Size can be customized according to the yield of mud and the extraction dosage of addition, the greasy filth after three phase separation, still containing the difficult removing in part
Oil and be difficult to the colloid removed, asphalitine, depth separation need to be carried out, according to the similar principle that mixes, organic solvent is selected to make
For extractant.Extractant is added according to 1:1-1:3 (mass ratio) solid-to-liquid ratio by solvent tank 2, heating and temperature control is 40-
60 DEG C, stir 30-60min；
(5) oil remaining in greasy filth, colloid, asphalitine etc. are transferred in extractant under the action of extractant from mud,
It send through pumping to two-phase horizontal screw centrifuge 9, carries out the two-phase laminated flow of extract liquor, mud；
(6) extract liquor isolated, after separating into solvent recovery machine 13, solvent enters solvent recovery tank 14, and oil enters
Second crude oil temporary storage tank 15；The communicated band of mud is delivered to next processing unit；
(7) through second step treated greasy filth, minimizing is fairly obvious, and oil content, moisture content are decreased obviously, but at this time
Mud in can residual fraction extractant and the oil that is not extracted of part, therefore the communicated band of greasy filth is sent into vacuum drier 10,
The organic solvent and oil of evaporation enter solvent recovery tank 14 through condensing recovery, and body refuse enters body refuse collecting pit 11.It thoroughly solves to have
Solvent residual and the halfway problem of oil-sludge treatment, realize greasy filth minimizing, innoxious, are the recycling of next step greasy filth
Using laying a solid foundation.
Specific embodiment 1:
Illustrate the utility model specific embodiment by taking " three mud of refinery " in certain oil field as an example.Selected greasy filth is sticky in aterrimus
Shape, oil, mud, water are tightly combined, no lamination, measure greasy filth oil-containing 11.4% through gravimetric method and oven drying method, aqueous
35.6%, remaining is solid matter.
Using the above-mentioned greasy filth of 10kg is added in greasy filth collecting pit 5 in advance, 30kg process water is added by technique water storage tank 1
And 0.05kg greasy filth cleaning agent, 60 DEG C are heated to, and stir 30min at such a temperature.Sediment pump is opened, by greasy filth cleaning solution
Be sent into Three-phase decanter centrifuge 7 together and carry out oil, water, mud three phase separation: the oil isolated enters the first crude oil temporary storage tank 12；Water
Greasy filth collecting pit 5 is recycled to recycle；The communicated band 3 of silt is delivered to greasy filth agitator tank 8.Thereto by solvent tank 2
10kg greasy filth extractant is injected, is heated to 40 DEG C, and stir 30min at such a temperature.Sediment pump is opened, by greasy filth extract liquor one
Rise and be sent into two-phase horizontal screw centrifuge 9 progress extract liquor, mud two-phase laminated flow: the extract liquor isolated is separated through solvent recovery machine 13
Afterwards, solvent enters solvent recovery tank 14, and oil enters the second crude oil temporary storage tank 15；The communicated band of mud is delivered to vacuum drier 10.
The organic solvent and oil of evaporation enter solvent recovery tank 14 through condensing recovery, and mud is outer after 2h is dry to drain into body refuse collecting pit 11,
To further dispose.
Measuring that treated through gravimetric method and oven drying method, greasy filth oil content is 2.8%, moisture content 16.7%, without obvious
Extractant smell, treated greasy filth gross weight 7.1kg, greasy filth decrement 29% that treated.
Specific embodiment 2:
It chooses for the ground sludge in another oil field and illustrates specific example of the present invention.Greasy filth oil-containing 8.9%, it is aqueous
45.4%, remaining is solid matter.
It is being rejected in greasy filth after biggish stone, branch and house refuse in advance, processing technological flow and addition medicament
Ratio heats washing+solvent extraction and centrifuge separation with example 1, through adding medicine " after the disposing technique that combines, greasy filth oil-containing
1.7%, aqueous 15.4%, without obvious extractant smell, treated greasy filth gross weight 6.1kg, greasy filth decrement that treated
39%.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
