Description
Technical field
The present invention relates to technical field of oil extraction equipment, especially a kind of novel greasy filth Separation process arrangements.
Background technology
The processing of Sludge in Oilfields is a problem very severe under current Environmental Protection Situation, by taking Shengli Oil Field as an example,
Need to handle about 20 ~ 300,000 tons of oily sludge every year, oily sludge oil content it is high up to 20 ~ 30%, it is low less than 5% because former
The presence of oily composition, the processing for leading to oily sludge is increasingly complex, and conventional processing mode has burning, pyrolysis, hot water washed-out sand, surpasses
The modes such as sound wave cleaning treatment, wherein burning and exhaust gas being generated the methods of pyrolysis and increases carbon emission, hot water washed-out sand, ultrasound
The modes such as wave cleaning generally require combination surfactant, and waste water is generated after having handled, can also increase metal ion in sludge, is produced
Raw secondary pollution.
Invention content
The purpose of the present invention is aiming at the deficiencies in the prior art, using ideal separating medium, using its switching characteristic,
Greasy filth is detached, and recycles its liquid phase, achievees the purpose that realize disposal of oily sludge.Meanwhile system uses heat pump to not
Heating, cooling processing is carried out with process, can also further reduce energy consumption.
The present invention is realized by following technological means：1# agitator tanks pass through 1# stop valves, slush pump connection cooling point
From device, 2# agitator tanks connect cooling separator by 2# stop valves, slush pump, and pipeline is connected cooling separator by 1# water pumps all the way
Heat exchanger is connect, two road pipelines connect cooler by horizontal screw centrifuge, and pipeline connects cooling to heat exchanger by heat pump all the way
Device, cooler connection 2# water pumps, two road pipeline connection surge tanks, surge tank connects 1# agitator tanks respectively by oil storage tank and 2# is stirred
Mix tank.
Advantageous effect of the present invention：Reasonable design is practical, realizes the purpose of disposal of oily sludge, time saving and energy saving, reduces
Energy consumption improves productivity effect, and popularity is suitble to use.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific embodiment
As shown in Figure 1, a kind of novel greasy filth Separation process arrangements, mainly by 1# agitator tanks 1,2# agitator tanks 2,1# stop valves
3rd, 2# stop valves 4, slush pump 5, cooling separator 6, horizontal screw centrifuge 7, cooler 8, heat pump 9,1# water pumps 10, heat exchanger
11st, surge tank 12,2# water pumps 13 and oil storage tank 14 are formed；1# agitator tanks 1 connect refrigerated separation by 1# stop valves 3, slush pump 5
Device 6,2# agitator tanks 2 connect cooling separator 6 by 2# stop valves 4, slush pump 5, and 6 one road pipeline of cooling separator passes through 1# water
10 connection heat exchanger 11 of pump, two road pipelines connect cooler 8 by horizontal screw centrifuge 7, and 11 1 road pipeline of heat exchanger passes through
Heat pump 9 connects cooler 8, and cooler 8 connects 2# water pumps 13, two road pipeline connection surge tanks 12, and surge tank 12 passes through oil storage tank
14 connect 1# agitator tanks 1 and 2# agitator tanks 2 respectively.
Embodiment 1：
The present invention is to be detached and can recycled contained crude oil in oil sludge and sand to oil sludge and sand using dedicated separation medium, in the process
Separating medium have switching characteristic, aqueous solution can be with dissolving crude oil in 50 degrees centigrade, and it is Celsius that temperature is reduced to 20
It is insoluble with crude oil when spending, therefore can be readily recycled, waste water, waste liquid are not generated, and whole energy consumption is relatively low, maximum temperature
Only 55 degrees Celsius, the waste water of surfactant and metal ion containing there are many will not be generated as washed-out sand method, it will not picture
Burning method, pyrolysismethod need very high energy consumption like that, therefore can effectively substitute traditional oil sludge and sand such as washed-out sand method and burning method
Treatment process.
Oil sludge and sand is fed first into 1# agitator tanks 1 and 2# agitator tanks 2, here with adding the temperature of separating medium about
50 DEG C of water is sufficiently mixed, stirs, and two equipment alternate use, controls two by 1# stop valves 3,2# stop valves 4 and sets
Then by the castering action of slush pump 5, mixed slurry transportation is cooled down to cooling separator 6 for standby switching,
Refrigerant of the low-temperature receiver from 1# water pumps 10, and in this initial gross separation part oil, oil phase enters heat pump 8；Rest part enters
Cooler 7 carries out separation of solid and liquid, and solid is expelled directly out；Liquid phase also carries out further water-oil separating into heat pump 8, and oil phase is directly received
Collect and stored in 2# water pumps 13；Water phase is transported to heat exchanger 11 by 1# water pumps 9 and heats up, and heat source herein equally comes
From the medium of 1# water pumps 10；Water phase after heating enters surge tank 12, and passes through oil storage tank 14 and water phase is returned 1# agitator tanks 1
Next round processing is carried out with 2# agitator tanks 2.More than flow is connected by pipeline.
