[0022] Please refer to the attached Figure 1 , a device for separating oil fume from the exhaust gas of a thin oil station, comprising a first central pipe 1, a second central pipe 2, a flange 3, a separator 4, a lateral outlet pipe 5, a secondary collection pipe 6, a filter screen 7, a packing layer 8, a support device, and a discharge pipe 9. The first central pipe 1 is arranged in the middle of the separator 4, the first central pipe 1 extends to a position below the lower filter screen 7, the first central pipe 1 is connected to the second central pipe 2 through the flange 3, the lateral outlet pipe 5 is arranged on the upper side of the side wall of the separator 4, the secondary collection pipe 6 is arranged on the side wall position of the first central pipe 1, and the outlet end of the secondary collection pipe 6 is directly below the outlet end of the lateral outlet pipe 5. The filter screen 7 is symmetrically arranged above and below in the separator 4, the packing layer 8 is located in the middle position between the upper and lower filter screens 7, the packing layer 8 is a fine steel wool layer, the support device is arranged at the bottom position of the separator 4, and the discharge pipe 9 is arranged at the lower side position of the side wall of the separator 4.

[0023] With the above technical solution, the first central pipe 1 is connected to the smoking pipe of the thin oil station fan. After the oil product in the thin oil station returns to the oil tank after absorbing heat from the cooled equipment, the hot flue gas emitted is sucked away by the smoking fan and enters the separator 4 at high speed through the first central pipe 1 and the second central pipe 2. Specifically, the first central pipe 1 extends into the position below the lower filter net 7. Therefore, after the flue gas is discharged into the separator 4 and contacts the bottom of the separator 4, it will flow upward and fully contact the packing layer 8, enabling the packing layer 8 to adsorb and filter the oil ions in the flue gas. Then, the treated flue gas flows upward and is discharged through the lateral outlet pipe 5. The flue gas will contact the pipe wall of the lateral outlet pipe 5 again, enabling the pipe wall to adsorb the oil ions in the treated flue gas again. Since the diameter of the first central pipe 1 is larger than that of the secondary collection pipe 6, the jet principle is utilized to generate a certain negative pressure at the nozzle of the secondary collection pipe 6 inside the pipe of the first central pipe 1. Thus, the secondary collection pipe 6 will aspirate the flue gas discharged from the outlet of the lateral outlet pipe 5 again, causing the flue gas that has completed one treatment to flow back to the first central pipe 1 again, making it flow downward and contact the packing layer 8 for the second time to achieve secondary flue gas separation. The separated oil stains can be effectively collected, solving the problems of short adsorption time of the oil stain particles in the flue gas and small contact area with the packing layer 8. Most of the oil stain particles are filtered, adsorbed, and accumulated by the internal packing to form oil droplets, which then drip to the bottom of the separator 4 for storage and are regularly discharged and recycled through the discharge pipe 9.

[0024] Specifically, by setting the flange 3, when operations such as maintenance and replacement of the lower separator 4 are required, the entire separator 4 can be directly taken out by disassembling the flange 3, which is convenient for subsequent operations and improves the convenience of maintenance.

[0025] In some embodiments, the outlet end of the lateral outlet pipe 5 is inclined towards the outlet end of the secondary collection pipe 6, playing a certain guiding role to make the discharged flue gas flow towards the secondary collection pipe 6. The outlet end of the secondary collection pipe 6 is in the shape of an inverted horn to improve the suction effect.

[0026] In some embodiments, the support device includes support rods 10. The support rods 10 are evenly spaced at the bottom of the separator 4, and the number of support rods 10 is three. By setting the support rods 10, the support rods 10 support the separator 4. With the number of support rods 10 being three, a tripod shape is achieved, realizing a more stable support.

[0027] In some embodiments, two valves 11 are provided on the side wall of the separator 4.

[0028] It should be noted that the opening position of the upper valve 11 corresponds to the position of the packing layer 8. When the adsorption function of the packing layer 8 for oil ions is poor, the packing layer 8 can be replaced through the upper valve 11. The opening position of the lower valve 11 is located below the lower filter net 7. The staff can check the oil discharge situation after filtration through the lower valve 11, which is convenient for cleaning the adsorbed oil inside the separator 4 and avoiding blockage.

[0029] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
