Abstract
The utility model relates to a recovery device for tail gas of oil-field natural gas, and belongs to the oil-field natural gas exploitation and recovery machinery. The utility model solves the defect that the ignition lamp of the tail gas of the oil-field natural gas is burnt. A natural gas tail gas pipeline is connected with a pressure bin recovery device with a propelling pump in series. The gas natural gas of the natural gas tail gas pipeline is pressed into a pressure bin, and is cooled and pressurized to cause the gas natural gas to convert into the liquid natural gas. The liquid natural gas enters the natural gas transportation pipeline through the liquid natural gas extracting pump and the ball valve.
Description
Oil field of the present utility model Sweet natural gas device for recovering tail gas relates to oil and gas exploitation and reclaims machinery.
In the past, oil field Sweet natural gas tail gas is often put a day lamp and is burnt, and has wasted the energy.
The purpose of this utility model is to propose a kind ofly to reduce environmental pollution, and save energy reclaims Sweet natural gas, the oil field Sweet natural gas device for recovering tail gas of turning waste into wealth.
The technical scheme of oil field of the present utility model Sweet natural gas device for recovering tail gas is to be connected in series gas propulsive pumps and pressure storehouse by three check valves in the Sweet natural gas exhaust pipe, being provided with cooling cooling screen and liquid natural gas in the pressure storehouse and extracting piston pump; Sweet natural gas tail gas under the propelling pressure of gas propulsive pump, is pressed into the pressure storehouse in the Sweet natural gas exhaust pipe, along with the cooling of cooling cooling screen and the continuous increase of pressure in the pressure storehouse, Sweet natural gas can become liquid by gas, is extracted piston pump by liquid natural gas then and extracts away
Accompanying drawing 1 is the structural profile sketch of oil field of the present utility model Sweet natural gas device for recovering tail gas;
Accompanying drawing 2 is A-A cross-section structure sketches of oil field of the present utility model Sweet natural gas device for recovering tail gas;
Accompanying drawing 3 is that the liquid natural gas of oil field of the present utility model Sweet natural gas device for recovering tail gas is extracted piston pump C-C cross-section structure sketch;
Among the figure, pressure storehouse 8, by check valve 6, be connected in series mutually with natural gas line 4, cooling screen 9 is arranged to reduce temperature in the pressure storehouse 8, on the natural gas line 4 of inlet end one side in pressure storehouse 8, socket Sweet natural gas boost pump, this pump are connected by the fixed link 2 that injects chute 1 by inner sleeve 5, outer tube 3, inner sleeve 5 and the outer tube 3 of end band check valve 6 and form; The connection opening place of pressure storehouse 8 outlet sides, one side and natural gas line 4 is equipped with check valve 6, can play safety valve when 8 superpressures of pressure storehouse.When this Sweet natural gas boost pump advanced, its end check valve 6 can be closed, and the Sweet natural gas boost pump can be with ducted Sweet natural gas, and the breather check valve 6 by pressure storehouse 8 enters pressure storehouse 8, and when this Sweet natural gas boost pump retreated, its end check valve 6 was opened; At this moment, the check valve 6 in pressure storehouse 8 is closed under action of pressure, and the check valve 6 that ducted Sweet natural gas is opened by its boost pump end enters pipeline space; Circulation and so forth, ducted Sweet natural gas constantly is advanced in the pressure storehouse 8.Along with pressure constantly increases, temperature constantly descends, and when reaching certain numerical value, the natural gas in the pressure storehouse 8 will become liquid natural gas.
The mud hole 7 that is located in natural gas line 4 and the pressure storehouse 8 will be discharged impurity.
Liquid natural gas in the pressure storehouse 8 can be extracted piston pump by liquid natural gas and constantly extract, and backs down spherical valve 21 and enters the liquid natural gas pipeline thereby strengthen internal pressure.Liquid natural gas is extracted piston pump 10 and is made up of liquid recovery tube, piston 16, connecting rod 17, stroke machine 22, ball valve 21,, the stroke machine drives the reciprocating motion of the pistons with non-return valve function by connecting rod, continuous extracting liq Sweet natural gas, spherical valve can be opened under the pressure difference effect, and liquid natural gas is finally entered natural-gas transfer pipeline.
The connecting rod 17 of valve head 25 is fixed by cross shaft collar 26, dispose spring 13 between cross shaft collar 26 and the nut 27, cross shaft collar 26 is fixed on the piston 16 by fixed orifices 28, cooperatively interacting of the non-return valve function of piston and spherical valve function realized the continuous extraction and the recovery of liquid natural gas.
Oil field of the present utility model Sweet natural gas device for recovering tail gas.Can reduce environmental pollution, save energy reclaims Sweet natural gas, turns waste into wealth, and has exploitation to be worth.
