[0027] Embodiment

[0028] Please refer to Figures 1-4 The present application is a double-oil-separation-cylinder oil-gas separator, comprising a base 200 and a separation cylinder assembly 100 screw-fitted on the upper part of the base 200.

[0029] The separation cylinder assembly 100 comprises an outer oil separation cylinder 101, an end cover 102 fixed on the top of the outer oil separation cylinder 101, an inner oil separation cylinder 103 passing through the middle position of the end cover 102, and a flow guide plate arranged inside the outer oil separation cylinder 101. The inner part of the outer oil separation cylinder 101 is concentrically provided with an inner container 106, which is screw-connected with the peripheral side of the inner oil separation cylinder 103. The outer oil separation cylinder 101 serves as an outer container, and the built-in flow guide plate is arranged staggered and inclined to increase the length of the airflow path and promote the coagulation of oil droplets.

[0030] The base 200 comprises a threaded ring 203 screw-seal connected with the bottom of the outer oil separation cylinder 101, a mounting ring 201 integrally connected with the threaded ring 203, an oil collection groove 204 fixed on the lower part of the mounting ring 201, a control valve 206 arranged at the bottom of the oil collection groove 204, and a heating element 205 arranged around the bottom of the peripheral side of the oil collection groove 204. The lower edge of the mounting ring 201 is fixed with a controller 202, which is connected with the heating element 205. The threaded ring 203 is used to fix the outer oil separation cylinder 101 on the base 200 to ensure the sealing property. The mounting ring 201 and the threaded ring 203 are designed integrally to provide stable support. The oil collection groove 204 collects the lubricating oil separated from the gas. The control valve 206 is used to control the discharge of the lubricating oil in the oil collection groove 204. The heating element 205 is arranged around the bottom of the oil collection groove 204 to prevent the lubricating oil from solidifying due to low temperature, maintain the fluidity and separation efficiency, and the controller 202 is responsible for monitoring and adjusting the working state of the heating element 205.

[0031] Specifically, the outer oil separator 101 and the inner liner 106 form a first oil-gas separation chamber, and the inner oil separator 103 has a second oil-gas separation chamber inside, with the bottoms of the first oil-gas separation chamber and the second oil-gas separation chamber communicating with each other; the first oil-gas separation chamber has a guide plate, which includes annular plate one 107 and annular plate two 108 arranged alternately. Both annular plate one 107 and annular plate two 108 are inclined and are arranged alternately. Annular plate one 107 is equidistantly arranged on the inner wall of the outer oil separator 101, while annular plate two 108 is equidistantly arranged on the outer wall of the inner liner 106. The surfaces of annular plate one 107 and annular plate two 108 are coated with an oleophilic and hydrophobic coating.

[0032] Furthermore, an air inlet pipe 104 is provided on the side of the end cap 102, and the air inlet pipe 104 is connected to the first oil-gas separation chamber; an exhaust pipe 105 is provided on the top of the inner oil separator 103, and at least one layer of filter medium 109 is embedded in the top of the inner oil separator 103. The filter medium 109 is composed of multiple layers of fiber materials with different pore sizes, and an electrostatic adsorption membrane is sandwiched between each layer.

[0033] The specific implementation scheme of this technical solution is as follows:

[0034] I. Intake Stage: Oil-containing compressed air enters the first oil-gas separation chamber through the intake pipe 104;

[0035] II. Preliminary separation: When the gas passes through the annular plate 107 and the annular plate 108, the oil droplets are promoted to coagulate and settle due to the oleophilic and hydrophobic coating on the surface of these plates. Larger oil droplets fall directly into the oil collection tank 204.

[0036] Third, secondary separation: After the initial separation, the gas enters the second oil-gas separation chamber in the inner oil separator 103. Here, the gas needs to pass through multiple layers of filter media 109, where the fibrous material and electrostatic adsorption membrane further capture the remaining tiny oil droplets.

[0037] IV. Exhaust Stage: The finally purified gas is discharged through the exhaust pipe 105 at the top of the inner oil separator 103 for subsequent use or further treatment.

[0038] V. Oil Management: The lubricating oil collected in the oil collection tank 204 can be discharged periodically through the control valve 206 for recycling or treatment. The heating element 205 is activated as needed to maintain the temperature inside the oil collection tank 204, prevent the lubricating oil from freezing, and also help improve the separation effect.

[0039] This technical solution effectively improves oil-gas separation efficiency through multiple separation mechanisms, reduces the amount of residual lubricating oil in compressed air, thereby protecting downstream equipment and extending their service life. In addition, the heating function helps adapt to different working environment conditions, ensuring the reliable operation of the separator.
