Abstract
The utility model relates to a novel high-speed electro-desalting static mixer, belonging to the technical field of mechanical mixing in crude oil processing. The novel high-speed electro-desalting static mixer mainly comprises a barrel body with an inlet flange and an outlet flange at two ends as well as a plurality of mixing units. Each mixing unit also comprises semicircular, dish-shaped or curve-side trapezoidal vanes and is fixedly connected to the barrel body through flat steel with the length equal to that of the barrel body in series. Retainer rings formed by combining check rings and catch levers are welded among both ends of the barrel body and the mixing units. As the mixer with the structure can lead fluids repeatedly to rotate and flow among the mixing units and join, strike and cut for a plurality of times, thereby achieving the good mixing effect, and due to the dual fixing functions of the flat steel and the retainer rings, the mixer can be applied to high-speed electro-desalting systems with large viscosity, high flow speed and high requirements for mixing differential pressure.
Description
Technical field
The present invention relates to a kind of novel high speed electro-desalting static mixer, the static mixing device that especially a kind of pipe interior fluid mixes mutually is mainly used in the hybrid technology field of crude oil and water in the crude Treatment technology.
Background technology
Along with rapid economy development, people increase gradually to the demand of crude oil, and the oil property that makes exploitation come out becomes increasingly complex.Will certainly increase the weight of the burden of electro-desalting system when utilizing the traditional electrical desalting technology to handle these crude oil, therefore before crude oil enters electro-desalting, want fully to mix with certain washings earlier than row with regard to requiring.By mixing, profit is disperseed, increase the contact area between the profit, the salinity in the crude oil just is dissolved in the water, enters the electro-desalting high voltage electric field after profit mixes and separates, and the salinity in the crude oil just is separated with water.The effect of static mixer fully mixes crude oil with water exactly, and traditional static mixer can only be applied in the simple technology of some oil properties, and for the viscosity height, flow velocity is fast, and than great, the complicated oil product that salt content is high can not satisfy the mixed effect requirement.This is because traditional static mixer has only single a kind of mixed cell, and fixing in mix cylinder can not be satisfied the strength and stiffness requirement, major part is rushed in, and oil pipe results in blockage or more serious quality accident, thereby make the undercompounding of crude oil and water, can not form uniform oil-water emulsion, salinity can not fully be dissolved in and be removed in the water and do not reach desalting effect.
At above-mentioned prior art, retrieval is found, application number is that 2007201827286,87201156,911127560 and 962462195 domestic and international patent application all improves prior art, but all do not have from dealing with problems in fact, therefore when handling the complicated crude oil of high viscosity, high flow rate, high specific gravity and high salinity, all because of the constant intensity of its inner part and rigidity can not meet the demands in various degree quality accident appears.
Summary of the invention
The purpose of this utility model is the problem that the fixing requirement that can not satisfy strength and stiffness for the mix cylinder inner part that overcomes static mixer in the prior art is prone to when handling the complicated crude oil of high viscosity, high flow rate, high specific gravity and high salinity, has proposed a kind of novel high speed electro-desalting static mixer.It is S type mixed cell and X type mixed cell that this device adopts the mixed cell of two kinds of patterns, the cross arrangement of two kinds of pattern mixed cells can make not only that the mixing of crude oil and water reaches good mixed effect in the high speed electro-desalting system, satisfy high speed electro-desalting electric field desalination index, and on the structure of mixed cell, adopted double fixed, thereby solved the problem that mixed cell is flushed away in mixed process.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of novel high speed electro-desalting static mixer comprises mixer tube, is installed in the suction flange and the outlet(discharge) flange at mixer tube two ends and is built in mixer tube interior S type mixed cell and X type mixed cell.Described S type mixed cell and X type mixed cell are welded on the band steel of certain specification according to model, and are fixed on the mixer tube together by band steel.And it is angled between every group of blade of composition S type mixed cell or X type mixed cell.Between mixer tube two ends and S type and X type mixed cell, all be welded with the back-up ring of fixation.Back-up ring is to be combined by the baffle ring of certain specification and pin.
In high speed electro-desalting system, the novel high speed static mixer can directly be connected in the inflow pipeline.The washings pipeline can be installed in distance the last period of static mixer, makes crude oil and water have a segment distance to carry out premixed before entering static mixer, so more can improve the mixed effect in static mixer.After crude oil and water enter static mixer with certain flow rate, because being provided with two kinds of mixed cells in the static mixing tube is S type mixed cell and X type mixed cell, the cross arrangement of two kinds of pattern mixed cells, in the time of can making fluid and when left-handed and dextrorotation, not only push the fluid in the pipeline to periphery from the center, also push peripheral fluid to center, thereby formed good radial circular flow.This radial circular flow not only exists in cell cube, also is present in simultaneously in the space between the cell cube.Because the effect of radial circular flow, crude oil and water will produce in pipeline such as motions such as " bump ", " cutting ", " rotation ", " displacements ", increased the contact area of moisture and oil droplet on the one hand, break up and be dispersed in water droplet in the oil phase on the other hand, thereby reach good mixed effect, guarantee after the desalination of high speed technology of electric de-salting that salt content reaches technic index in the crude oil.
S type mixed cell in the utility model and the cross arrangement of X type mixed cell, and can determine following several models according to process conditions: SX type, SXS type, XS type, XSX type.The blade shape of S type mixed cell or X type mixed cell has semicircle, dish or bent limit trapezoidal.Angular range between every group of blade is 0～90 °, preferred 75 ° and 90 ° according to the practical operation experience.The structure one that plays the double fixed effect in static mixer is a band steel, and it is 20～50mm that its band steel specification has width, preferred 30mm; Its length equals mixer tube length; The 2nd, by the back-up ring that baffle ring and pin are formed, wherein baffle ring and pin all are to be made by the stainless steel round steel, and the diameter of baffle ring and pin can be Φ 10～Φ 40mm, preferred Φ 16.
The utility model beneficial effect is: 1. the present invention is simple in structure, be convenient to make, and good dispersion, volume is little, and flow is big, is a kind of efficient, energy-conservation, novel high speed electro-desalting static mixer.2. two kinds of mixed cell cross arrangements of the present invention and structurally adopted double fixed, be applicable to the complicated crude oil of handling high viscosity, high flow rate, high specific gravity and high salinity, and guaranteed the mixed effect of crude oil and washings, thereby guaranteed after the desalination of high speed technology of electric de-salting that salt content reaches technic index in the crude oil.
