Description
Technical Field
The utility model belongs to separator especially relates to an oil well oil storage tank natural gas recovery drying device.
Background
In the oil field operation, the less oil production block of liquid production volume and associated gas volume or the oil well block in alpine region are used for keeping in the oil well oil storage tank of producing crude oil, can save some associated natural gas, the natural gas that discharges through the oil storage tank can contain a large amount of light oil and fog, all be large-scale fixed to the recovery unit of associated natural gas at present, the technology processing mode is ageing, area is big, the energy consumption is big, the expense is big should not move, poor and difficult the washing to the drying effect of natural gas, many oil field districts are because of the tolerance is few, pressure is little, can't input the pipe network, only the evacuation burns off, not only waste resources but also can cause environmental pollution.
Disclosure of Invention
The utility model aims to overcome the not enough of prior art, provide an oil well oil storage tank natural gas recovery drying device.
The utility model discloses a drying device is retrieved to oil well oil storage tank natural gas comprises maintenance flange, casing, degreaser, defroster, overhauls flange central point and puts and be equipped with the gas outlet, go up fixed surface and have casing, lower fixed surface have a cyclone, casing top central point puts and is equipped with the gas outlet, and casing inside upper end is fixed with fixed extension board one, and the defroster is fixed at fixed extension board one upper surface, and casing inside lower extreme is fixed with fixed extension board two, and the degreaser is fixed at fixed extension board two upper surfaces.
As a further improvement of the utility model, more than one air inlet is arranged on the periphery of the upper part of the cyclone separating cylinder.
As a further improvement, the air outlet of the center of the maintenance flange is connected with a gas pipe, the gas pipe is positioned inside the cyclone separation cylinder, and the length of the gas pipe is less than that of the cyclone separation cylinder.
As a further improvement of the utility model, a criss-cross grid is arranged in the oil remover.
The natural gas recovery and drying device of the oil well oil storage tank effectively utilizes the associated natural gas in the oil storage tank to realize the purpose of heat preservation and self-supporting heating in winter, thereby not only solving the problem of supplying heating fuel, but also avoiding the waste of associated natural gas emptying resources; the device has high space utilization rate, is directly connected with the flange of the oil storage tank, can effectively utilize the gas phase space of the oil storage tank, and has more compact structure. The device is internally provided with a cyclone separation mechanism, an oil remover and a demister, so that the natural gas drying and separating effect is good; be equipped with in and overhaul the flange, it is more convenient that the device clearance is changed.

Detailed Description
The utility model discloses an oil well oil storage tank natural gas recovery drying device comprises maintenance flange 1, casing 4, degreaser 2, defroster 3, overhauls flange 1 central point and puts and is equipped with the gas outlet, the upper surface is fixed with casing 4, lower surface is fixed with cyclone separator 7, cyclone separator 7's upper portion ring is equipped with more than one air inlet 11, overhauls flange 1 central gas outlet department and is connected with gas-supply pipe 10, gas-supply pipe 10 is located cyclone separator 7 inside, and the length of gas-supply pipe 10 is less than cyclone separator 7's length, and the associated natural gas exists in the upper portion gas phase space in oil storage tank 12, fixes maintenance flange 1 on oil storage tank 12 upper portion, and cyclone separator 7 can be located the upper portion gas phase space in oil storage tank 12 simultaneously, utilizes the internal pressure of jar to send the natural gas into cyclone separator 7 interior upper portion from air inlet 11, then enters the gas pipe 10 from the bottom gas inlet end of the gas pipe 10 in the cyclone separation cylinder 7, and the larger liquid drops and the entrained crude oil are primarily separated by using the cyclone centrifugal principle.
The central position of the top end of the shell 4 is provided with an air outlet 9, the upper end inside the shell 4 is fixed with a first fixed support plate 5, the demister 3 is fixed on the upper surface of the first fixed support plate 5, the lower end inside the shell 4 is fixed with a second fixed support plate 6, the oil remover 2 is fixed on the upper surface of the second fixed support plate 6, and the oil remover 2 is internally provided with a vertically and horizontally staggered grid 8. The associated natural gas after preliminary separation enters the oil eliminator 2 through the gas delivery pipe 10 and the gas outlet hole at the central position of the maintenance flange 1, the associated natural gas is in charge contact with the grating 8 in the oil eliminator 2 by utilizing the convection impact principle to achieve the purpose of secondary separation, and finally enters the demister 3 to separate and dry the associated natural gas entrained with mist, so that the final drying purpose is realized, and the treated dry natural gas is discharged from the gas outlet 9 at the top end of the shell 4 and is used by a heating burner of an oil storage tank.
The device can be directly overhauled and the wearing parts can be replaced through the overhauling flange 1 externally, the operation in a closed space is avoided, and the potential safety hazard is reduced.
