Abstract
The utility model relates to a differential pressure sensor for the automatic control of the interface of liquid oils with water, which is characterized in that supporting bars (9) and (7) are fixed to the top part of a liquid storage tank (1), and the supporting bars (9) and (7) keep perpendicular to the bottom of the liquid storage tank. The utility model is suitable for the automatic control of interface of crude oil with water and the liquid level detection of crude oil in large oil storage tanks in order to output corresponding pressure signals.
Description
The utility model is the differential pressure pick-up of a kind of automatic controlling liquid oils and water termination, is specially adapted to crude oil and the automatic control of water termination and the Level Detection of detection and crude oil thereof in the large-scale oil storage tank, exports corresponding pressure signal.The pagoda type level pressure sensor was once arranged in the past, and it can only export a kind of liquid level pressure signal, is not suitable for the detection of tracer liquid oils and water termination.Advantage of the present invention is with the position of setting, and two level pressure sensors are installed, and therefore exports two different liquid level pressure signals, and this pressure signal is input to signal processing apparatus, can realize the automatic control of liquid oils and water termination.
The purpose of this utility model, be that crude oil contains certain moisture content in the time of will solving owing to exploitation, when crude oil is input to hold-up vessel, crude oil of Xing Chenging and water termination gradually, be difficult to mensuration and can not in time open the pipe valve that discharges water automatically, cause a jar inner product dilutional hyponatremia, reduce oil reserve, perhaps can not in time close the pipe valve that discharges water, a difficult problem that causes crude oil also to be lost automatically as water.
Therefore, the present invention is in time automatically to open the pipe valve that discharges water, and puts ponding in clean jar and improves the effective rate of utilization of storage tank and in time close the pipe valve that discharges water automatically, prevents the design proposal of crude oil loss.
Accompanying drawing is the structure diagram of the differential pressure pick-up of automatic controlling liquid oils and water termination, and it is made up of two pagoda type pressure transducers, i.e. sensor housing (2) and (3); Cramp bar (9) and (7); Leading difference pipe (10) and (8) forms.
In order to illustrate and convenience of calculation, on accompanying drawing, be provided with storage tank (1) and automatic pipe valve (4).The crude oil height value is (H1) in jar, oil density is (d), the density of water be upper control limit upper thread that (D), crude oil and water form be the lower limit parting line of (6), crude oil and water formation be (5), by upper control limit upper thread (6), the height that changes to lower limit parting line (5) is H2.Cramp bar (7) and (9) are fixed on the top of storage tank (1), but must keep vertical with the hold-up vessel bottom, and its sensor housing (3) is with the upper end of the breach of (2), respectively with consistent by upper control limit upper thread (6) and the lower limit parting line (5) set.Therefore the difference in height between sensor housing (3) and (2) just equals the difference in height of upper control limit upper thread (6) and lower limit parting line (5).Because the crude oil that when exploitation is moisture is divided into crude oil and water gradually, so lower limit parting line (5) rises to gradually with the upper control limit upper thread of setting (6) and overlaps, so H2, is changed to the height value of water by the height value of crude oil.
If: the static pressure of sensor housing (3) and (2) institute sensing is respectively (P3) and (P2), and by connecting pipe (8) and (10), is delivered to same signal processing apparatus.
〔P3〕＝dgH1┉┉┉（1） 〔P2〕＝（dgH1＋DgH2）┉┉┉（2）
(2)-(1); I.e. (P2)-(P3)=(dgH1+DgH2)-dgH1
＝DgH2
D is the density of water in the formula, can record, and g is an acceleration of gravity, and dgH1 is the static pressure value of crude oil.
(H2) is that the upper control limit upper thread (6) of setting and the difference in height so the DgH2 of lower limit parting line (5) are known numbers, if D is constant, DgH2 is a definite value, can be used as the control signal of the upper control limit upper thread of setting.This signal is delivered to signal processing apparatus, and this device sends instruction immediately, opens automatic pipe valve (4), begins to discharge ponding, reaches the purpose that automatic control discharges water.
Owing to discharge water automatically, upper control limit upper thread (6) drops to gradually with the lower limit parting line (5) of setting and overlaps, so H2 is changed to the height value of crude oil by the height value of water.
If: the static pressure of sensor housing (2) and (3) institute sensing is respectively (P2) (P3), and is delivered to same signal processing apparatus by connecting pipe (10) and (8).
〔P′2〕＝dgH1┉┉┉（3） 〔P′3〕＝（dgH1－dgH2）┉┉┉（4）
(3)-(4); I.e. (P ' 2)-(P ' 3)=dgH1-(dgH1-dgH2)
＝dgH2
D is the density of crude oil in the formula, so dgH2 is known number, if d is constant, dgH2 is the control signal that a definite value can be used as the lower limit parting line of setting.This signal is delivered to signal processing apparatus, and this device sends instruction immediately, closes automatic pipe valve (4), stop to discharge water, so crude oil and water termination can not continue to descend, and has controlled effectively and can not in time close discharge water pipe valve and the phenomenon of loss crude oil in the past.
Because in the storage tank, constantly input contains the crude oil of certain moisture content so the parting line (5) of crude oil and water, rise to upper control limit upper thread (6) gradually and overlap, the signal processing apparatus DgH2 value of getting back is sent instruction immediately, and automatic pipe valve unlatching is discharged water.
Realize the automatic control of large-scale oil storage tank ponding discharging so fully and prevent the automatic control that crude oil runs off, and often export the liquid level value dgH1 signal of crude oil, be input to signal processing apparatus, can detect the height value of crude oil exactly.
This is the hard nut to crack in oil field in all parts of the country, is to want to solve and the great technical task failing so far rationally to be solved always.
