Technical Field

[0001] This utility model relates to the field of oil and gas recovery technology, specifically to a cooling treatment device for oil and gas recovery. Background Technology

[0002] Oil and gas are generated during the volatilization of oil products during production, storage, transportation, and loading / unloading. This not only causes serious oil product losses but also affects air quality and human health, and brings many safety hazards. In order to eliminate safety hazards and improve energy utilization, oil and gas recovery is necessary. Oil and gas recovery uses cooling technology to separate oil and gas.

[0003] Currently, water-cooled cooling methods for oil and gas cooling have a large contact distance between the cooling pipes and the heat, which is not conducive to rapid heat exchange. In addition, the contact position between the heat and the cooling pipes is fixed, and the end of the cooling pipe closer to the heat suffers greater losses, which reduces the service life of the pipes. Therefore, we propose a cooling treatment device for oil and gas recovery to solve the above-mentioned problems. Utility Model Content

Both the upper and lower ends of the cooling pipe are connected to connecting pipes. The lower end of the cooling pipe is connected to a water outlet hose, which passes through the side of the cooling box.

[0007] A water pump is installed on the left side of the cooling box. The water pump has an inlet pipe connected to its inlet end and a water delivery hose connected to its outlet end. One end of the water delivery hose is connected to the upper end of the cooling pipe.

[0009] Preferably, the gas delivery pipes are arranged in a spiral shape, and the lowest end of the gas delivery pipes is connected to the oil outlet pipe.

[0010] Preferably, the cooling pipes are distributed at equal angles with respect to the longitudinal centerline of the gas transmission pipe, and the cooling pipes are interconnected by connecting pipes.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: a cooling treatment device for oil and gas recovery, including a cooling box 1, an oil storage tank 2 is provided inside the lower end of the cooling box 1, an oil drain pipe 3 is connected to the side of the oil storage tank 2, an oil outlet pipe 4 is connected to the upper part of the oil storage tank 2, an air supply pipe 5 is connected to the upper end of the oil outlet pipe 4, an air inlet pipe 6 is connected to the upper end of the air supply pipe 5, the air inlet pipe 6 penetrates the upper wall of the cooling box 1, and an exhaust pipe 7 is connected to the side of the oil outlet pipe 4.

[0025] Furthermore, the gas transmission pipe 5 is spirally distributed, and the lowest end of the gas transmission pipe 5 is connected to the oil outlet pipe 4, which can extend the oil and gas transmission time. Moreover, along the inclined gas transmission pipe 5, the oil can be concentrated into the oil outlet pipe 4, avoiding residue in the gas transmission pipe 5.

[0026] Furthermore, the exhaust pipe 7 is distributed at an angle and penetrates the upper wall of the cooling box 1, which can discharge excess gas and prevent it from accumulating in the cooling device.

[0027] A water pump 8 is installed on the left side of the cooling box 1. The water inlet of the water pump 8 is connected to the water inlet pipe 9, and the water outlet of the water pump 8 is connected to the water delivery hose 10. One end of the water delivery hose 10 is connected to the upper end of the cooling pipe 11. A motor 13 is installed at the upper end of the cooling box 1. The output end of the motor 13 is connected to the reciprocating screw 14. A connecting seat 15 is connected to the outside of the reciprocating screw 14. The end of the connecting seat 15 is connected to the connecting pipe 12. A heat sink 16 is installed on the side wall of the air delivery pipe 5. One end of the heat sink 16 passes through the cooling pipe 11. Both the upper and lower ends of the cooling pipe 11 are connected to the connecting pipe 12. The lower end of the cooling pipe 11 is connected to the water outlet hose 17. The water outlet hose 17 passes through the side of the cooling box 1.

[0028] Furthermore, the cooling pipes 11 are distributed at equal angles with respect to the longitudinal centerline of the gas transmission pipe 5, and the cooling pipes 11 are interconnected through connecting pipes 12, which allows cold water to flow continuously in the cooling pipes 11 to cool the oil and gas.

[0029] Furthermore, the heat sink 16 is evenly distributed on the gas supply pipe 5, and there is a gap between the heat sink 16 and the cooling pipe 11, which allows the heat sink 16 to transfer heat and realize rapid heat exchange between the gas supply pipe 5 and the cooling pipe 11.

[0030] Furthermore, the connecting pipe 12 has an arc-shaped structure, and the connecting pipes 12 distributed vertically are staggered, which can prolong the flow time of cold water in the cooling pipe 11, so that the cold water can fully contact the heat.

[0031] Specifically, when using this oil and gas recovery cooling device, the oil and gas are transported to the gas delivery pipe 5 through the inlet pipe 6, and the heat is concentrated at the heat sink 16. At the same time, the water pump 8 is connected to the power supply, and cold water is transported through the water inlet pipe 9. The cold water enters the cooling pipe 11 through the water delivery hose 10. The cooling pipe 11 passes through the heat sink 16, so it can quickly achieve heat exchange and cool the oil and gas in the gas delivery pipe 5. The separated oil is concentrated in the oil storage tank 2 through the oil outlet pipe 4. Since the gas delivery pipe 5 is spiral, it can ensure that the separated oil is concentrated in the oil outlet pipe 4 and enters the oil storage tank 2, avoiding residue in the gas delivery pipe 5. The excess gas is discharged through the exhaust pipe 7. After the cold water flows in the connecting pipe 12 and the cooling pipe 11, it is finally discharged from the water outlet hose 17, realizing the circulation of cold water.

[0032] When the motor 13 is powered on, the reciprocating screw 14 connected to the output end is rotated, thereby controlling the connecting seat 15 connected to the outside to move up and down reciprocally, which in turn controls the connecting pipe 12 and the cooling pipe 11 to move up and down reciprocally. The cooling pipe 11 slides inside the heat sink 16. Adjusting the contact section between the cooling pipe 11 and the heat sink 16 makes the cooling pipe 11 heat evenly, improving the service life of the cooling pipe 11. The movement of the cooling pipe 11 also enables dynamic heat dissipation, improving the cooling efficiency of the oil and gas. After separation, the valve on the oil drain pipe 3 can be opened to clean the oil. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
