Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas separation in a lubricating oil station, in particular to an oil and gas separation and recovery system for a lubricating oil station. Background Art

[0002] The lubrication oil station is a system for lubricating gas turbines and generators. It is used to provide the necessary lubricating oil to gas turbines and generators to ensure that the rotating parts of these equipment can be adequately lubricated and cooled during operation.

[0003] During the operation of the equipment, a certain amount of oil-gas mixture will be generated in the oil tank due to the friction and heating of the oil. If the oil-gas mixture is not discharged in time, it may cause the pressure in the oil tank to increase, thereby affecting the normal operation of the lubrication system. However, when the oil and gas are discharged, the oil will be discharged with the gas, causing environmental pollution. Based on this, the utility model proposes an oil-gas separation and recovery system for a lubricating oil station. Utility Model Content

The oil and gas are transported to the oil and gas separation device through the range hood. The filter layer is designed by utilizing the characteristics of smoke rising and oil falling, so as to achieve the effect of condensation, falling and collection of oil and gas while the gas is discharged.

[0006] The technical solution further defined in the utility model is:

[0007] Furthermore, the oil-gas separation device includes a vertical oil-gas separator, and the filter layer is located above the vertical oil-gas separator and close to the connection with the exhaust pipe.

[0008] Furthermore, the filter mesh layer is composed of stacked layers of wire mesh.

[0009] Furthermore, in the stacked wire meshes, the mesh holes of the adjacent upper and lower layers of wire meshes are staggered.

[0010] Furthermore, the oil outlet end of the oil-gas separation device is connected to an oil drain valve via a pipeline.

[0017] like Figure 2 As shown, when the oil tank 1 of the original lubricating oil station is discharged through the range hood 2 and the exhaust pipe 5, the oil-containing smoke is discharged to the outside at the same time, causing environmental pollution. Therefore, this embodiment provides an improved lubricating oil station oil and gas separation and recovery system to solve the problem of oil and gas overflow in the oil tank 1 of the oil station, see Figure 1 , specifically including a range hood 2 connected to the top of the oil tank 1 of the gas station. The range hood 2 of this embodiment is an exhaust fan. The exhaust end of the exhaust fan is connected to an oil-gas separation device 4 through a connecting pipe 3. The oil-gas separation device 4 is specifically a vertical oil-gas separator. The upper end thereof discharges the gas after oil-gas separation through an exhaust pipe 5, and the lower end is connected to an oil drain valve 7 through a pipe.

[0018] It should be noted that a filter mesh layer 6 is installed in the oil and gas separation device 4 in this embodiment, and the filter mesh layer 6 is installed near the connection of the exhaust pipe 5. The filter mesh layer 6 is specifically composed of stacked layers of wire mesh, wherein the mesh holes of adjacent upper and lower layers of wire mesh are staggered to increase the path of the gas when it is discharged upward. The multiple layers of wire mesh are integrated into a mesh filter mesh layer 6, which is conducive to further condensation and falling of residual oil and gas in the gas after oil and gas separation, thereby improving the separation effect and reducing pollution.

[0019] Specifically, in this embodiment, an oil collecting barrel 8 is placed below the oil drain valve 7 , and the oil drain valve 7 is used to regularly drain the oil in the oil-gas separation device 4 into the oil collecting barrel 8 .

[0020] It should be noted that, in this embodiment, a vertical oil-gas separator is taken as an example. In some other implementations, the oil-gas separation device 4 can also be a vertical tank body, and only the aforementioned multi-layer wire mesh integrated mesh filter layer 6 is installed above the tank body, which can also achieve the effect of oil and gas condensation and falling, thereby realizing oil and gas separation.

[0021] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
