Description
Technical field
The utility model is applied to gas field separator automatic drain system, can realize separator long-term safety automatic drain, specifically, is a kind of rock gas station separator automatic draining device.
Background technique
Electric ball valve automatic drain system is adopted in the separator blowdown of rock gas station, gas field, Yulin, and this system is made up of differential pressure fluid level transmitter, PLC control cabinet, electric ball valve and discharge opeing pipe valve three parts.Give the PLC control section when the two position signal of separator liquid level transmitter LT impression, export the alternating signal of 220V then and give electric ball valve, control the switch of electric ball valve, thereby realize the automatic control of separator blowdown.
Automatic Control Theory according to the separator blowdown, calculate the fluid level transmitter two position by containers size and change discharge opeing liquid measure once, and regularly carry out the demarcation of a lifting rate, by PLC director demon configuration, open number of times with electric ball valve and multiply by the inferior liquid measure of blowdown, be total metering of blowdown liquid measure.
Production practices proof separator electric ball valve automatic drain system failure rate is higher, the liquid phase error in dipping is big, and the normal operation rate is basically about 65%.Be forced to carry out manual discharge opeing when electric ball valve is malfunctioning, not only increased the workload of automatic-control instrument professional and technical personnel field maintenance, and control improperly slightly is easy to make pressurized gas to enter the sewage jar, brought security risk to production.
Summary of the invention
The purpose of this utility model is to provide a kind of rock gas station separator automatic draining device, and its maintenance and replacing are simple, convenient, need not debugging, the workload of deduction and exemption automatic-control instrument professional and technical personnel field maintenance; Rate of fault is low, long service life, the minimizing operative employee's of gas gathering station workload; Choke is tight, prevents that pressurized gas from entering the sewage jar, reduces security risk, reduces engineering construction investment and gas field and safeguards improvement expenses, reduces cost of production.
The utility model is achieved in that
Comprise separator 1, electric ball valve 3, measure water-meter 4, rock gas delivery valve 5, rock gas delivery valve 5 and electric ball valve 3 UNICOMs, measure water-meter 4 and rock gas drain valve 5 UNICOMs are equipped with separator 1 on the top of this device.
The utility model also adopts following technological scheme:
Replace rock gas drain valve 5 with knock out drum 8.
The bottom of knock out drum 8 is provided with plug 7.
Knock out drum 8, electric ball valve 3, knock out drum 8, measure water-meter 4, restriction orifice 6 be UNICOM successively.
Advantage of the present utility model is: implement rock gas drain valve automatic drain system and estimate that once investment is 2.32 ten thousand yuan, save 2.099 ten thousand yuan than electric ball valve automatic drain system, by a gas gathering station 3 separator (production separators are installed, two metering separators) calculate, only one of electric ball valve automatic drain system just can save 6.297 ten thousand yuan.It is 4.739 ten thousand yuan that electric ball valve adds restriction orifice automatic drain system estimation one-time investment, carries out separator electric ball valve automatic drain system of gas gathering station when transforming, and only needs about 0.32 ten thousand yuan of investment.
Maintenance and replacing are simple, convenient, need not debugging, have reduced or remitted the workload of automatic-control instrument professional and technical personnel field maintenance; Rate of fault is low, and long service life has reduced the operative employee's of gas gathering station workload; Choke is tight, has prevented that pressurized gas from entering the sewage jar, reduced security risk; Prolong the working life of electric ball valve, reduced the workload of the manual discharge opeing of the operative employee of gas gathering station, reduced the workload of automatic-control instrument professional and technical personnel field maintenance; Prevented that pressurized gas from entering sewage jar 2, reduced security risk.
Description of drawings
Accompanying drawing 1 is the utility model rock gas drain valve automatic draining device structure journey schematic representation;
Accompanying drawing 2 adds restriction orifice apparatus structure schematic representation for the utility model electric ball valve.
Embodiment
As shown in Figure 1, be rock gas drain valve pumping equipment, when the sewage of separator 1 bottom and condensate reach certain liquid level, rock gas drain valve 5 is opened the beginning discharge opeing automatically, sewage is under the driving of rock gas self pressure, can realize round-the-clock, automatically work continuously, make the connate water in the separator 1 realize having water just row, anhydrous full automation program of closing automatically, choke is tight, the automatic sedimentation dirt is carried out discharging regularly, after filtering through filter, realizes accurate metering to liquid measure by the measure water-meter of back.Rock gas drain valve 5 is in the automatic drain process, and big right gas drain valve 5 bottom liquids can't emptying, can leave suitable liquid level, has guaranteed the zero leakage of blowdown valve rock gas.At the liquid dirt and the dregs of its bottom deposit, can regularly remove by sewage draining exit.
As shown in Figure 2, electric ball valve adds the restriction orifice pumping equipment, the liquid of separating from separator 1, first knock out drum 8 of at first flowing through, bigger foul and impurity in the filter liquide, reduce residue, booty is to the wearing and tearing of electric ball valve 3 spools, after electric ball valve 3 is opened blowdown automatically, flow of liquid is filtered less solid particle and impurity through second knock out drum 8, prevent that restriction orifice 6 apertures are blocked, liquid by measure water-meter 4 metering after, through restriction orifice 6 current limliting blowdowns to sewage jar 2, the effect of restriction orifice 6 is to increase electric ball valve 3 downstream back pressures, reduces the front and back pressure reduction of electric ball valve 3.
According to the technological process of three kinds of separator automatic drain systems, the difference of pressing the required capital equipment of drainage system, three kinds of automatic drain technologies are carried out economic comparative analysis such as following table:
