Description
Technical field
The invention provides a kind of field produces device, especially a kind of gas and oil separating plant.
Background technology
Oil pumper contains crude oil and a small amount of natural gas from oil well produced Produced Liquid.Natural gas can be separated as fuel, the liquid in the conveyance conduit is heated, to reduce the oil transportation resistance.At present gas-liquid separator housing is arranged, bottom one side of housing is equipped with feed tube, and opposite side is equipped with drain pipe, and an end of escape pipe is positioned at the top other end of housing inner chamber and draws from the bottom of housing.Liquid forms the gas compartment after entering in the housing above the housing inner chamber, the gas in this space flows out through escape pipe.In the use procedure, when few or gas consumption was large when the gas flow that produces, the liquid in the housing rose, and can enter escape pipe and flowed out, and polluted, and produced and leaked, and is low with the security of gas, after escape pipe is blocked, can affect normal production.
Summary of the invention
Technical problem to be solved by this invention is, a kind of gas-oil separator is provided, and it can prevent that Produced Liquid from entering escape pipe.
The present invention realizes like this, a kind of gas-oil separator, it has housing, bottom one side of housing is equipped with feed tube, opposite side is equipped with drain pipe, dividing plate is arranged at the top at described housing inner chamber, the middle part of dividing plate is fixed with the tapered valve shell, the tapered valve outer casing underpart is caught the water drum body, in the tapered valve shell taper valve core is installed, the lower end of taper valve core is connected with ball float, top is equipped with guide post, between guide post and the tapered valve shell the first spring is installed, and the tapered valve shell above taper valve core has steam vent, the pressure-reducing valve shell also is installed above the dividing plate, in the pressure-reducing valve shell valve ball is installed, the second spring is arranged above the valve ball, pressure-reducing valve shell inner cavity and accumulator intracavity inter-connection, the accumulator inner chamber also is connected with the tapered valve shell inner cavity, also have hole for back flow on the tapered valve shell, the upper end of escape pipe is positioned at the dividing plate top, the lower end is communicated with the gas outlet, and the separation umbrella is arranged above the liquid outlet of described feed tube.
Also have dirt pocket at described dividing plate, dirt pocket with go out pipe and be connected.
Adopt the gs-oil separator of said structure, rational in infrastructure, good separating effect can prevent effectively that Produced Liquid from entering escape pipe, has avoided the environmental pollution that therefore causes, and has guaranteed the normal production in oil field.
Description of drawings
Fig. 1 is the schematic diagram of structure of the present invention.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present invention.
As shown in drawings, a kind of gas-oil separator of the present invention, it has housing 7, bottom one side of housing is equipped with feed tube 3, opposite side is equipped with drain pipe 24, dividing plate 9 is arranged at the top at described housing 7 inner chambers, the middle part of dividing plate is fixed with tapered valve shell 10, the tapered valve outer casing underpart is caught water drum body 20, taper valve core 19 is installed in the tapered valve shell, the lower end of taper valve core is connected with ball float 8, top is equipped with guide post 18, and the first spring 17 is installed between guide post and the tapered valve shell, and the tapered valve shell above taper valve core has steam vent 23, pressure-reducing valve shell 13 also is installed above the dividing plate, valve ball 15 is installed in the pressure-reducing valve shell, the second spring 16 is arranged above the valve ball, pressure-reducing valve shell inner cavity and accumulator 14 intracavity inter-connections, the accumulator inner chamber also is connected with the tapered valve shell inner cavity, also have hole for back flow 22 on the tapered valve shell, the upper end of escape pipe 6 is positioned at the dividing plate top, the lower end is communicated with gas outlet 4, and the umbrella 5 of separation is arranged above the liquid outlet of described feed tube.
During use, oil well produced liquid flows out through drain pipe in feed tube enters housing again.In the flow process, the gas in the Produced Liquid is from upwards flowing between tapered valve shell and the taper valve core, enters space more than the dividing plate through steam vent, flows out through escape pipe again.The partially liq of carrying secretly in the gas is fallen space below the dividing plate through hole for back flow.When the speed of gas discharging during greater than the speed of γ-ray emission, the liquid level of dividing plate below can rise, and ball float rises thereupon, the drive taper valve core moves up, with steam vent and hole for back flow sealing, liquid can not enter the space of dividing plate top, prevents that it from flowing out through escape pipe.At this moment, store the gas of certain pressure in the first spring pressurized, the accumulator.After finding that escape pipe is discharged without gas, escape pipe can be sealed, in the liquid of dividing plate below new γ-ray emission be arranged, liquid level can constantly descend, gas pressure in the space of dividing plate below constantly increases, when this pressure was increased to certain value, gas pressure overcame the pressure of the second spring, moves on the valve ball, gas enters the accumulator inner chamber through the pressure-reducing valve shell inner cavity, increase the gas pressure in the accumulator, ball float is descending with liquid level, and suffered pressure diminishes gradually.When ball float drops to certain position, taper valve core falls under the effect of the elastic force of the first spring, the pressure of gas in the accumulator and deadweight, break away from the tapered valve housing, gas in the space of dividing plate below is again from upwards flowing between tapered valve shell and the taper valve core, enter the above space of dividing plate, flow out through escape pipe again.So repetitive operation can guarantee that in the gas process, the liquid in the space below the dividing plate can not enter escape pipe, has prevented its leakage.
Described the first spring is installed between guide post and the tapered valve shell by the gear nose of guide post middle and lower part.
Also have dirt pocket 12 at described dividing plate 9, dirt pocket with go out to manage 11 and be connected.Like this, the dirt that the dividing plate top produces can enter dirt pocket, discharges through going out pipe again.Dirt pocket is arranged on the large-scale gs-oil separator usually with going out to manage.
Described accumulator is a casing.
On large-scale gs-oil separator, can Pressure gauge be set on the top of housing.
Described ball float is connected to the lower end of taper valve core by connecting rod 21.
Hole for back flow one end is close on the dividing plate upper surface, communicates with the space of dividing plate top.
Catch the partially liq that the water drum body is mingled with in can the gas with its inner chamber of flowing through and catch the formation drop, can drip after drop increases.
Below the described housing supporting leg 1 can be arranged.The bottom of housing can be communicated with sewage draining exit 2.
