Description
Technical field
The utility model relates to a kind of well mouth of oil well residual gas recycling device, is specifically related to a kind of well mouth of oil well residual air and reclaims the supercharging gas injection device.
Background technology
At present, the most of oil field of China for small gas well think little of, for large-scale oil well all install at each oil well mouth that big-and-middle-sized residual air reclaims the supercharging gas injection device, cost is large, the power power consumption is large, payment imbalance etc., for small gas well without residual gas recycling device, so not only caused waste, and air has been caused to pollution.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, provide a kind of simple in structure, reasonable in design, easy for installation, simple to operate, can be according to residual air size automatic start-stop, compressor operating is stable, and the well mouth of oil well residual air of energy-saving and emission-reduction reclaims the supercharging gas injection device.
Its technical scheme is: well mouth of oil well residual air reclaims the supercharging gas injection device, comprise the aqueous vapor pre-separation cylinder with oil-gas mixture entrance, the lower end of described aqueous vapor pre-separation cylinder is provided with tapping valve, be provided with the gas-water separation baffle plate in described aqueous vapor pre-separation cylinder, described aqueous vapor pre-separation cylinder is connected with the input port of compressor by input channel, described input channel is provided with valve, be provided with the counterweight ball float opened and closed for by-pass valve control in described aqueous vapor pre-separation cylinder, described aqueous vapor pre-separation cylinder is provided with boost pressure controller, the delivery outlet of described compressor is connected with oil-gas pipeline by output channel, described output channel is provided with the pressure controller of giving vent to anger.
The temperature controller that is respectively equipped with radiator on described compressor and opens for controlling radiator.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, easy for installation, simple to operate, can be according to residual air size automatic start-stop, compressor operating be stable, energy-saving and emission-reduction.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, well mouth of oil well residual air reclaims the supercharging gas injection device, comprise the aqueous vapor pre-separation cylinder 2 with oil-gas mixture entrance 1, the lower end of described aqueous vapor pre-separation cylinder 2 is provided with tapping valve 3, be provided with gas-water separation baffle plate 4 in described aqueous vapor pre-separation cylinder 2, described aqueous vapor pre-separation cylinder 2 is connected with the input port of compressor 9 by input channel 5, described input channel 5 is provided with valve 6, be provided with the counterweight ball float 7 opened and closed for by-pass valve control 6 in described aqueous vapor pre-separation cylinder 2, described aqueous vapor pre-separation cylinder 2 is provided with boost pressure controller 8, the delivery outlet of described compressor 9 is connected with oil-gas pipeline by output channel 10, described output channel 10 is provided with the pressure controller 11 of giving vent to anger.
The temperature controller 13 that is respectively equipped with radiator 12 on described compressor 9 and opens for controlling radiator 12.Can play overtemperature prote, automatic heat radiation, protect effective.
The below that is positioned at oil-gas mixture entrance 1 in described aqueous vapor pre-separation cylinder 2 is provided with heat baffle plate 14.Can barrier gas flow downward by heat baffle plate 14, extended the application life of aqueous vapor pre-separation cylinder 2.
Operating principle: the well head natural gas enters aqueous vapor pre-separation cylinder 2 by oil-gas mixture entrance 1, after natural gas enters aqueous vapor pre-separation cylinder 2, after gas-water separation baffle plate 4 and aqueous vapor pre-separation cylinder 2 are removed impurity and liquid phase, through boost pressure controller 8 controlled pressures, enter the input port of compressor 9 through input channel 5 by valve 6, compressed machine 9 compressions are inputted on-the-spot oil-gas pipeline by the pressure controller 11 of giving vent to anger after boosting.When the liquid phase in aqueous vapor pre-separation cylinder 2 builds up to certain altitude, by counterweight ball float 7 valve-offs 6, open tapping valve 3 when stopping air inlet the liquid phase in aqueous vapor pre-separation cylinder 2 is discharged, after discharge opeing, counterweight ball float 7 is opened valve 6 and can be worked on.
Carry out gas-liquid separation due to natural gas before entering compressor, made into the natural gas of compressor relatively purely, guaranteed that compressor operating is stable, significantly extended maintenance period and the application life of compressor; Owing to having adopted admission pressure control, stablized the inlet pressure of compressor, also make well head pressure keep stable simultaneously; Can connect motor forward/backward rotation automatic straightening controller on compressor, the power supply wrong can be become a full member automatically like this, stable, easy to operate.
The utility model can be to energy recovery, improves effects of energy saving and emission reduction remarkable, realizes the sky discharge, prevents air pollution, and volume is little, lightweight, cost is low, simple to operate.
