Description
Technical field
The utility model relates to a kind of crude oil electro-desalting dehydrator that the refining of petroleum industry is used.
Background technology
Crude oil must remove its contained Yan Heshui through electric desalting and dewatering device earlier before the refinery deep processing, to alleviate the work-ing life that the burn into of follow-up equipment is prolonged catalyzer.At present, both at home and abroad mostly oil field and the employed electric desalting and dewatering device of refinery are horizontal equipment, the set-up mode of battery lead plate mainly contain level with vertical two kinds.The disclosed crude oil electro-desalting dehydrator that battery lead plate vertically is set of Chinese patent CN1604808A, the axis parallel of battery lead plate and tank body, the effective cross section that has taken tank body basically is regional, in the hope of forming more electric field, improving the tank body space availability ratio.But this does not have positive effect for the ratio of desalinization and the dehydration rate that improve crude oil, because oil-water mixture stopped in electric field 1～2 second, can reach required ratio of desalinization and dehydration rate; In this case, to take the effective cross section zone of tank body and form more electric field be exactly unnecessary to battery lead plate.This scheme has caused the waste of battery lead plate material because of the height of battery lead plate is too high.
Summary of the invention
The purpose of the utility model provides a kind of crude oil electro-desalting dehydrator, to solve the too high problem that causes the battery lead plate waste of material of the existing height because of battery lead plate of existing crude oil electro-desalting dehydrator.
For addressing the above problem, the technical scheme that the utility model adopts is: a kind of crude oil electro-desalting dehydrator is provided with tank body; Tank body is provided with inlet tube, oil outlet pipe, rising pipe, X-former, is vertically installed with battery lead plate in the tank body, the axis parallel of battery lead plate and tank body; It is characterized in that: inlet tube is located at the bottom of tank body, and oil outlet pipe is located at the top of tank body, is positioned at the middle part of tank body axial length; The height of battery lead plate is 400～1000 millimeters, and the mid point of battery lead plate height is positioned on the horizontal plane through the tank body axial line, in one group of battery lead plate; The number of plies of battery lead plate is an odd number, ground connection of adjacent two-layer battery lead plate, and one links to each other with the X-former output terminal; The battery lead plate that is positioned at both sides in one group of battery lead plate links to each other tank ground with the X-former output terminal.
Adopt the utility model, have following beneficial effect: (1) is because the height of battery lead plate is lower, so can avoid the waste of battery lead plate material.(2) because the height of battery lead plate is lower, can be less with the distance between the tank body inner side-wall relative in one group of battery lead plate with it at the battery lead plate of both sides, can form electric field between said battery lead plate and the tank body inner side-wall with enough strength of electric field.The central region that the electric field that forms between above-mentioned electric field and the adjacent two layers battery lead plate traverses the tank body xsect, continuously, do not have a slit.All can receive effect of electric field when oil-water mixture is flowed from bottom to top in tank body, help improving the ratio of desalinization and the dehydration rate of crude oil.
The utility model is mainly used in desalting and dewatering raw oil.
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
