The present invention forms by landing oil sump 1, strainer 2, liquor pump 3, high speed rotating bed 4, process furnace 5, thermo-chemical setting dihydration device 6, sludge sump 7, compound pump 8, pharmacy jar 9.
A kind of ground crude oil high speed centrifugation dewatering unit; Form by landing oil sump, strainer, liquor pump, high speed rotating bed, process furnace, thermo-chemical setting dihydration device, sludge sump, compound pump and pharmacy jar; Landing oil sump, strainer, liquor pump, high speed rotating bed, process furnace, thermo-chemical setting dihydration device is cascaded by preface; Thermo-chemical setting dihydration device oil outlet links to each other with good oil tank, and water outlet links to each other with the sewage jar; The outlet of the solid impurity of high speed rotating bed links to each other with sludge sump, the sewage outlet of high speed rotating bed with land oil sump and link to each other, sludge sump is higher than and lands oil sump, between be provided with overflow line; Advance at process furnace import or the oil sump that lands on the inlet line of liquor pump and be provided with chemicals dosing plant.
Land and deposit the moisture oil that lands in the oil sump, there is the coarse filtration structure this ingress, pond, makes through this structure and lands oil and obtain filtering; Ground crude oil arrives lift pump through strainer, promotes through lift pump and is transported to the high speed rotating bed, after handling through this rotating bed; Low wet oil, solid impurity and oily(waste)water are realized three phase separation; Low wet oil is transported to process furnace through pipeline, is provided with chemicals dosing plant in the process furnace ingress, after the process furnace heating; Low wet oil is transported to the thermo-chemical setting dihydration device; This device top links to each other with the gas inlet pipeline, and low wet oil purifies oil tank after treatment in self-cleaning oil outlet conveying is arrived at a station, and sewage arrives sewage plant through sewer pipeline.The solid impurity that comes out from high speed rotating bed bottom is transported to sludge sump, and sewage gets into and lands oil sump.Wherein chemicals dosing plant is made up of pharmacy jar and dosing pump, and the built-in emulsion splitter of pharmacy jar is transported to the process furnace source line after dosing pump promotes.
The high speed rotating bed is the round can type, and vertical ground is installed, and its top is provided with a ground crude oil import; This inlet links to each other with the outlet of forward liquor pump, and high speed rotating bed bottom is provided with high-speed electric expreess locomotive, and motor shaft links to each other with the high speed rotating bed; There is a low wet oil outlet at high speed rotating bed middle part, links to each other with the process furnace inlet, and a solid impurity outlet and a sewage outlet are arranged at the bottom; Solid outlet links to each other with sludge sump, sewage outlet with land oil sump and link to each other.
Compared with present technology the present invention has the following advantages:
1, this dewatering process is simple in structure, reasonable in design, and the equipment volume rootlet can form serial standardized product according to process lot size, and is on-the-spot quick and easy for installation, do not influence ordinary production.
2, adopt the high speed rotating bed, the impurity such as earth that will land in the oil separate, and have realized three phase separation, thereby will land the contaminative of oil drops to minimumly, makes it not influence the original system dehydration.
3, each equipment occupation of land of this system is few, and energy consumption is low, has reduced running cost, and obtains effect preferably.
