Description
The utility model relates to a kind of novel high-efficiency and energy-saving equipment that is used for oil field, the oil refinery dehydration of crude oil---material filling type earthing electrode electric dehydrator.
Electric dehydrator is the crude oil deep dehydrator that domestic and international oil field, refinery generally adopt, and it has played the irreplaceable effect of other non-electric field dehydration equipments.But the electric dehydrator of existing various form of structure is mainly used in handles conventional crude oil (proportion, viscosity less), and the heavy crude increasing for output still do not have more efficiently dehydration equipment at present.When utilizing conventional electric dehydration device processes heavy crude, ability drop (only being the 40-60% of Design Treatment amount), water cut in purified often take place to handle and deviate from phenomenons such as water oil content severe overweight, energy consumption increase exponentially.
Task of the present utility model is to provide a kind of novel material filling type earthing electrode electric dehydrator, and this kind electric dehydrator has stronger compliance to each quasi-oil, and conventional crude and heavy crude are all had good dehydrating effect.
The utility model is achieved in that it hangs suspender 3, insulating electrode rod 4, material filling type earthing electrode 5, wet oil distribution pipe 6, header 7, direct current pole plate 8 by regulating outside tank body 1, oil collecting pipe 2, the jar, suspender 9 is hung in a jar interior adjusting and oil baffle 10 is formed.Its assembling and architectural feature are: the interior upper, middle and lower portion of tank body 1 respectively flatly device oil collecting pipe 2(single tube is arranged), wet oil distribution pipe 6(4 root biserial) and header 7(biserial); In the opening that tank body 1 top evenly is provided with vertically respectively device a jar outer suspension suspender 3 and the insulating electrode rod 4 regulated arranged, suspender 3 by bearing pin respectively with direct current pole plate 8(lower floor between oil collecting pipe 2 and wet oil distributor 6) be connected; Hang suspender 9 top suspension rods and the welding of tank body 1 roof with interior adjusting of jar that suspender 3 is provided with at interval, the lower end is by bearing pin and direct current pole plate 8(upper strata) be connected; Insulating electrode rod 4 links to each other with 2 layers of direct current pole plate 8 respectively by lead; Be welded with material filling type earthing electrode 5 on wet oil distribution pipe 6 and the oil baffle 10.During work, wet crude enters 4 oil content pipe arrangements 6 respectively by wet oil inlet tube and header, by distribution pipe 6 wet crude is uniformly distributed in the jar along the tank body total length then.At this moment, oarse-grained free water sedimentation, the then even buoyance lift of wet oil, at first by filler battery lead plate 8, because the membrane of filler, broken bubble, collision, coalescence effect, make water droplet further gather into larger particles and sedimentation, the crude oil water content that enters weak electric field region by packing layer is controlled in the low scope.The low wet crude that enters weak electric field under the electric field force effect, than the drop of coarsegrain collide rapidly, coalescent and sedimentation, also rupture of membranes is agglomerated into larger particles and sedimentation to part floatingization water droplet owing to colliding under the electric field force effect.Like this, because the employing of material filling type grounding electrode plate, dehydrator gives water separation capability and is strengthened, and only has the very low floating shape oil of moisture content to enter high-strength DC electric field, prevented more highly aqueous direct impact effectively, guaranteed the stable of high-strength DC electric field battery lead plate.Clean oil through high-strength DC electric field effect is evenly collected along its total length by oil collecting pipe 2, and discharges through header and flowline, and the water of deviating from of tank body 1 bottom is then evenly collected and discharged through header and outlet pipe along its total length by header 7.The main design parameters of this kind electric dehydrator and technical-economic index are:
Design pressure: 0.4-1.6MPa, design temperature :≤150 ℃;
Accommodation: oil density≤0.95t/m
3, crude oil water containing≤20%;
Disposal ability: 100-120m
3/ h;
Water cut in purified :≤1%(viscous crude) ,≤0.5%(thin oil);
Deviate from the water oil content :≤2%;
Handle every t wet crude power consumption :≤0.38kwh.
The utlity model has modern design, reasonable, simple in structure, compliance is strong, treating capacity is big, dehydration multiple advantages such as quality is good, energy-conservation, is suitable for extensive use in oil field, each quasi-oil of refinery (particularly viscous crude) dewatering and desalting technology.
Accompanying drawing is a structural representation of the present utility model.(Fig. 1)
Below in conjunction with accompanying drawing enforcement of the present utility model is described further.
In the utility model, oil collecting pipe 2 is a single tube, with tank body 1 direct tube section with long, its top evenly has a series of bar-shaped troughs, the pipe range middle part has an oil drain out, the oil drain out place clean oil discharge pipe that is welded extends outside the tank body.Wet oil distribution pipe 6 is formed with the oil inlet pipe assembly welding that extends outside the tank body by 4 oil distributing pipes of biserial and header, and side direction and oblique direction down evenly have a series of oil outlets on it.Header 7 is that biserial water inlet pipe and the header gutter assembly welding outer with extending tank body forms, and its top evenly has a series of bar shaped water inlets.Jar outer regulate hang suspender 3 and jar in regulate that to hang suspender 9 upper and lower be suspension rod, the centre is the teflon insulation boatswain chair, there is screw thread on suspender 3 upper hanger tops in order to match with bolt.Material filling type earthing electrode 5 is formed by multilayer corrugated sheet assembly welding with holes, and its runner is cellular.It is the patented product seal with double-cone face electrode insulation rod of CN90226362 that insulating electrode rod 4 adopts the patent No..
