Abstract
The invention relates to an on-line sand removing and washing out device for crude oil. The on-line sand removing and washing out device comprises a sand remover, a sand washing-out device, a solid-liquid cyclone separator, a collecting chamber, and a jet pump, and is suitable for removing sand from a crude oil transportation pipeline. The sand remover can discharge the sand in the crude oil passing through the pipeline from the top pipeline; the sand washing-out device can separate the oil sand discharged by the sand remover. According to technology disclosed by the invention, the oil sand can be transported, separated and conveyed outside, and further circularly cleaned; compared with the conventional technology, the technology is good in treatment effect, and can be used for quickly and efficiently transporting the oil sand; meanwhile, the whole sand removing system is free of a motion component, and compact in structure; the on-line sand removing and washing out device can solve the problem that the crude oil contains sand in the crude oil on-line transportation process, avoids the safety problem caused by the fact that crude oil contains sand to the subsequent process, realizes continuous production, and achieves a higher automation level.
Description
Technical field
The present invention relates to crude oil washing/COW field, particularly relate to a kind of crude oil online desanding washed-out sand equipment.
Background technology
In oil exploitation process, because viscosity of crude is large, inevitably make part fine sand enter surface gathering system, after crude oil enters storage tank, under low flow regime, the fine sand in crude oil slowly can deposit to tank base.After long-time, the floor area ratio of tank body is more and more lower, has to clear up.Tradition manner of cleaning up is mainly deposited at sand and manually enters tank body after at the bottom of tank and clear up, and not only wastes time and energy, and there is safety problem.
Summary of the invention
For the weak point existed in the problems referred to above, the invention provides a kind of crude oil online desanding washed-out sand equipment.
A kind of crude oil online desanding washed-out sand equipment, is characterized in that: desander, sand-washing device, solid-liquid cyclone separator, collecting chamber, jet pump;
Desander oil-in one end is placed in crude oil pipeline, and oil-containing oil-sand is discharged in lower end, and crude oil is discharged in upper end.When oil pipeline transportation, because its internal operating pressures is high, the solid-liquid cyclone separator at sand-washing device top can be delivered directly to by the oil-sand that desander sucks.
Its course of work is: crude oil enters desander by pipeline, produces eddy current after flowing through desander, makes to deposit oil-sand below it in certain area coverage and suspends and fluidisation; Fluidised oil-sand is inhaled in the discharge pipe of desander under the effect of desander vortex centers negative pressure, enters the solid-liquid cyclone separator at sand-washing device top through pipeline; Water sand mixture realizes Separation of Solid and Liquid under the effect of solid-liquid cyclone separator, and oil water mixture overflows from top, and the oil-sand that sub-argument goes out discharges the collecting chamber falling into sand-washing device container bottom bottom solid-liquid cyclone separator.
Beneficial effect of the present invention is:
By the change to the passive sand removing process using of tradition, add crude oil desanding washed-out sand equipment in feed-line, not only solve after crude oil enters downstream tank body deposition and need manually to enter tank body cleaning problem, the safety problem caused when turn avoid labor cleaning; Can continuous prodution be carried out, higher automatization level can be realized.

Detailed description of the invention
Desander oil-in one end is placed in crude oil pipeline, and oil-containing oil-sand is discharged in lower end, and crude oil is discharged in upper end.When oil pipeline transportation, because its internal operating pressures is high, the solid-liquid cyclone separator at sand-washing device top can be delivered directly to by the oil-sand that desander sucks.
When sand-washing device bottom collection room oil-sand is full of, desanding system stops the conveying of oil-sand, and sand-washing device to bring into operation removing oil pattern with regard to the valve opening device bottom.
For oil-sand is thoroughly cleaned, utilize the oil-sand solid that a pipeloop and the desander that is arranged on sand-washing device container bottom come again in circulating collection room, wherein pipeloop extends through the charging aperture of solid-liquid cyclone separator from sand-washing device container bottom, and in closed circuit, a jet pump is installed, to improve the flowing pressure of mortar fluid.
During concrete use: crude oil enters desander by pipeline, after flowing through desander, produce eddy current, make below it, in certain area coverage, to deposit oil-sand and suspend and fluidisation; Fluidised oil-sand is inhaled in the discharge pipe of desander under the effect of desander vortex centers negative pressure, enters the solid-liquid cyclone separator at sand-washing device top through pipeline; Water sand mixture realizes Separation of Solid and Liquid under the effect of solid-liquid cyclone separator, and oil water mixture overflows from top, and the oil-sand that sub-argument goes out discharges the collecting chamber falling into sand-washing device container bottom bottom solid-liquid cyclone separator.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
