Abstract
A half cage type electrical desalter belongs to raw oil desalination and oil-water separation device and comprises a cylindrical desalter casing, an insulating electrode sleeve, a high-voltage leading-in rod, a raw oil input pipe, a raw oil output pipe, a water injection pipe, a water drainage pipe, an inner supporting seat, an insulating hang, a half cage type plate electrode, a desalter supporting base, and the like. The utility model is characterized in that the half cage type plate electrode is made up of two arched grate type cages with different radiuses and is coaxially fixed at the inner upper part of the desalter casing along the axial direction in an inserting and insulating manner, and the bastard faces of the arched grate type cages are parallel to a horizontal plane. The utility model integrates the structural advantages of a parallel-plate grate type plate electrode and a grate cage type plate electrode, makes full use of confined space inside the desalter, increases the electric field space between the two plate electrodes, reduces fluid flowing resistance, and prevents short circuit and tripping among polar plates.
Description
Technical field
The utility model belongs to crude oil desalting and oily water separating equipment.
Background technology
Contained salt is to be dissolved in the moisture content that crude oil wrapping in the crude oil.Petroleum chemical enterprise generally relates to the desalinating process of removing solubility salt in the crude oil, and desalinating process is to finish in the electrical desalter of special use.Its ultimate principle is: low viscosity crude oil after the preheating and hot water are injected electrical desalter, thorough mixing forms water solution of oil, make the solubility salt in the crude oil soluble in water, again to water solution of oil high-pressure electric field and add emulsion splitter, under the dual function of electrical forces and emulsion splitter, make oily water separation, get rid of brackish water, reach the purpose of crude oil desalting.This process is to carry out in electrical desalter continuously.
What generally adopt in the petroleum chemical enterprise at present, is cylindrical horizontal electrical desalter.Structure formation by battery lead plate in the tank body is divided into two kinds: a kind of is parallel flat comb formula electrode plate structure, and two battery lead plates of this structure can be horizontally disposed with also and can vertically be arranged in the tank body.Another kind is the squirrel-cage electrode plate structure, the cylindrical comb formula of two battery lead plates of this structure along tank body axially cover insert insulation and be fixed on jar intravital.The former is because of being subjected to the restriction of cylindrical tank skin, and electric field space is limited, and spatial electric field occupancy is lower in the tank body, and the desalting efficiency of crude oil is also low.Then fluid flow resistance is more apparent outstanding vertically to set up battery lead plate in this way, and production efficiency is restricted.The latter, be the squirrel-cage electrode plate structure in theory in the tank body spatial electric field occupancy increased, but because will constantly water filling in jar in the desalting treatment process, and crude oil has also been deviate from the moisture content that is being wrapped in demineralising process, these saliniferous moisture content all are deposited on the Lower Half of tank body, very easily cause short circuit between two-plate, the circuit trip device is stopped transport.This situation is recurrent in actual production process, thereby has influenced declining to a great extent of continuity production and actual output.
Summary of the invention
The purpose of this utility model is all the defective that remedies the electrical desalter of parallel flat comb formula electrode plate structure commonly used at present and squirrel-cage electrode plate structure, develop a kind of jar interior space that can make full use of and increase the electric field occupancy and can guarantee the continuity of desalinating process process again, and then the electrical desalter of enhancing productivity.
For achieving the above object, the technical solution of the utility model is: a kind of half cage electrical desalter is provided, it by cylindrical ladle bowl, insulated electrode sleeve pipe, high voltage electric import that rod, crude oil input tube, crude oil output tube, water injection pipe, water shoot, interior supporting seat, insulation are hung, half cage electrode, tank body outward base for supporting etc. form, wherein half cage battery lead plate is axially to insert insulation with axle sleeve by the arc comb formula cage of two different radiis along tank body to be fixed on top in the ladle bowl, and the string face of its arc comb formula cage is parallel with horizontal plane.
Compared with the prior art, the utility model combines the advantage of parallel flat comb formula battery lead plate and two kinds of structures of squirrel-cage battery lead plate, made full use of the finite space in the tank body, increased the electric field space between two battery lead plates, fluid flow resistance is little, prevented that the saliferous water surface rising that accumulates in the tank body bottom from very easily causing the possibility of short-circuit device tripping operation between two-plate, thereby guaranteed the continuity of production process, production efficiency can significantly improve.
Description of drawings
Fig. 1 is the radial section synoptic diagram of half cage electrical desalter structure.
Fig. 2 is the axial section synoptic diagram of half cage electrical desalter structure.
As shown in the figure, half cage electrical desalter be by cylindrical ladle bowl 1, insulated electrode cover 2, high voltage electric import rod 3, crude oil input tube 4, crude oil output tube 5, water injection pipe 6, water shoot 7, interior supporting seat 8,9, half cage battery lead plate 10 is hung in insulation and the outer base for supporting 11 of tank body constitutes.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing: with steel alloy weldering system one cylindrical ladle bowl 1, base for supporting 11, insulated electrode cover 2, crude oil input tube 4, crude oil output tube 5, water injection pipe 6, water shoot 7 outside the appropriate location of ladle bowl 1 fabrication and installation tank body.On ladle bowl 1 supporting seat 8 in the welding metal, insulation to be hung an end of 9 more fixedly connected with it, the other end is fixedlyed connected with half cage battery lead plate 10, also hangs internal layer half cage battery lead plate 10 9 fixing with outer half cage battery lead plate 10 through insulation again.Two-plate is connected with the external power source system by the high voltage electric leading-in rod 3 of insulated electrode cover 2 through lead.At last with two ball crown type alloy ladle bowl terminations and cylindrical ladle bowl 1 welded closure.Tank body is installed stable back crude oil input tube 4 and is connected with the crude oil preheating can, to receive the low viscosity crude oil of preheating, can regulate input by valve.Crude oil output tube 5 is accepted equipment with next and is connected, and can regulate work output by valve.Water injection pipe 6 is connected with the thermal water source, can regulate water injection rate by valve.Automatically controlled valve is installed on the water shoot 7 is connected the water displacement that to regulate brackish water, stably rest on certain altitude with water level and the oil water surface of guaranteeing brackish water, in order to avoid cause short circuit, assurance electric desalting effect stability with outer control system.
Tank body shell 1 can adopt 16MnR steel alloy sheet material, and tank diameter is controlled between 3～4M.
Insulation is hung 8 and can be adopted polytetrafluoroethylmaterial material.
Half cage battery lead plate, 10 available metal tubing or bar welding are made.
Half cage battery lead plate 10 can be installed one or more groups as one sees fit vertically according to the length of tank body and the treatment capacity of crude oil.
