[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See Figures 1-6 As shown, this utility model provides an oil-gas separator for oil depot oil-gas recovery, including an oil-gas separator box 1 and a digital display control panel 7. The oil-gas separator box 1 is provided with a cooling pipe structure 2 for cooling and recovering the introduced oil-gas. An electric fan 3 for air cooling the cooling pipe structure 2 is provided on the top side of the oil-gas separator box 1. An air outlet 9 is provided on the upper side of the oil-gas separator box 1. An inlet pipe 4 for introducing coolant is provided on the bottom side of the oil-gas separator box 1, and an outlet pipe 5 for discharging coolant is provided on the upper side of the oil-gas separator box 1.

[0031] See instruction manual attached Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the cooling pipe structure 2 includes four or more spiral cooling pipes 203 arranged in concentric circles. In practical applications, the concentric circle layout greatly optimizes space utilization efficiency, enabling the largest possible cooling area to be provided within the limited internal space of the oil-gas separator 1, thereby improving the efficiency of oil-gas cooling and recovery. The upper and lower ends of two adjacent spiral cooling pipes 203 are connected to each other in sequence to form a whole unidirectional pipe. This design, based on the concentric circle layout, ensures that the oil and gas can flow along a specific path in the cooling pipe, avoiding turbulence and short-circuit phenomena, ensuring that the oil and gas can fully exchange heat with the cooling medium, and effectively improving the cooling effect. The two ends of the spiral cooling pipes 203 extend from the upper side of the oil-gas separator 1 and are respectively connected to the inlet pipe 201 and the outlet pipe 202. The upper ends of the spiral cooling pipes 203 are connected to each other via upper connecting pipes 204, and the lower ends of the spiral cooling pipes 203 are connected to each other via lower connecting pipes 205. Each lower connecting pipe 205 has a collection pipe 206 connected to one side. The other end of the collection pipe 206 exits the oil-gas separator 1 and is connected to a drain pipe 207. An exhaust pipe 208 is installed on the upper side of the drain pipe 207. Each spiral cooling pipe 203 has a heat dissipation rib 13 on its inner side, and the cross-sectional shape of the heat dissipation rib 13 is arc-shaped. The lower connecting pipes 205, while connecting the spiral cooling pipes 203, also collect the condensed oil generated after cooling in each spiral cooling pipe 203 for subsequent discharge treatment.

[0032] An inner baffle 12 is installed between the outermost spiral cooling pipe 203 and the inner side of the oil-gas separator 1. The upper side of the inner baffle 12 is tightly and stably fixed to the inner top side of the oil-gas separator 1 by means of strong welding or high-strength bolts. The bottom side of the inner baffle 12 forms a ventilation gap with the inner bottom surface of the oil-gas separator 1, creating a special airflow channel. The air outlet 9 is located between the outer side of the inner baffle 12 and the inner side of the oil-gas separator 1. The air outlet 9 is precisely positioned between the outer side of the inner baffle 12 and the inner side of the oil-gas separator 1. This position was carefully chosen, as it works in conjunction with the ventilation gap to complete the ventilation and heat dissipation function of the entire equipment. After passing through the ventilation gap, hot air can be smoothly discharged to the outside of the oil-gas separator 1 through the air outlet 9, dissipating the heat generated during the cooling process in a timely manner, maintaining a suitable temperature inside the equipment, ensuring that the cooling pipe structure 2 can continuously and efficiently cool and recover oil and gas, and ensuring the stable operation of the entire oil-gas recovery system.

[0033] The top side of the oil-gas separator 1 is equipped with a baffle plate 8 to block and redirect the air outlet 9. The baffle plate 8 has an L-shaped cross-section. It effectively blocks the airflow that is directly discharged upward from the air outlet 9, preventing the airflow from flowing freely in all directions. The horizontal part extends above the air outlet 9, guiding the originally vertically upward airflow in a specific direction. This design not only prevents the discharged hot air from affecting surrounding equipment, but also optimizes the flow of surrounding air by utilizing the guiding effect of the airflow, thus assisting in the overall heat dissipation process of the equipment.

[0034] A first solenoid valve 10 is installed on the inlet pipe 4, and a second solenoid valve 11 is installed on the outlet pipe 5. The output terminal of the digital display control panel 7 is electrically connected to the input terminals of the first solenoid valve 10 and the second solenoid valve 11, respectively.

[0035] The support structure 6 includes several columns 601 fixedly installed on the bottom edge of the oil-gas separator 1. Each column 601 has a base plate 602 fixedly installed at its lower end, and the base plate 602 has several mounting holes 603.

[0036] Working principle:

[0037] Oil and gas cooling and recovery: Oil and gas enter the cooling pipe structure 2, which consists of multiple concentric spiral cooling pipes 203, through the intake pipe 201. The multiple spiral cooling pipes 203 are connected by an upper connecting pipe 204 and a lower connecting pipe 205 to form a unidirectional cooling pipe. Oil and gas enter through the intake pipe 201 and exit through the outlet pipe 202, completing the entire cooling process. The inner heat dissipation ribs 13 increase the heat dissipation area and improve cooling efficiency. An electric fan 3 provides air cooling to the cooling pipe structure 2. Simultaneously, coolant is introduced into the oil-gas separator 1 through the liquid inlet pipe 4. The coolant flows from bottom to top within the oil-gas separator 1 and exits through the liquid outlet pipe 5, further cooling the oil and gas and condensing and recovering the oil components. The air cooling and liquid cooling can be performed independently or simultaneously, depending on the actual situation.

[0038] Condensed oil collection and discharge: The condensed oil enters the collection pipe 206 through the lower connecting pipe 205 at the lower end of the spiral cooling pipe 203, and then flows into the drain pipe 207 for discharge. The exhaust pipe 208 is used to discharge the gas generated during the discharge process.

[0039] Ventilation and heat dissipation: The hot air generated by the air cooling system flows through the ventilation gap between the bottom side of the inner partition 12 and the bottom surface of the oil-gas separator 1, and is discharged to the air outlet 9. The baffle plate 8 blocks and redirects the air outlet 9 to optimize the ventilation effect.

[0040] Equipment installation and fixing: The oil-gas separator 1 is installed and fixed through the base plate 602 at the lower end of the bottom edge column 601 and the mounting hole 603.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
