DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] In order to improve the oil filtration rate, Figure 1-4 As shown, the self-gravity spiral oil-gas separator described in the utility model includes:

[0034] Outer barrel 1;

[0035] The spiral part 2 is arranged in the outer barrel 1;

[0036] The vacuum pump 3 is arranged on the outer barrel 1 .

[0037] When in use, the outer barrel 1, the spiral part 2 and the vacuum pump 3 are used for oil and gas separation, so that the gas-containing oil is discharged downward by the spiral under the help of its own weight, and the centrifugal force generated by the spiral can help the oil and gas separation, and the oil in the separated gas is intercepted through the multi-channel filtering structure, so that the oil collection rate is better and the gas purity is higher.

[0038] To separate oil and gas, for example, Figure 2 , 3 As shown in , 4, the utility model also includes that the spiral portion 2 includes:

[0039] The bottom of the round barrel 201 is fixed to the center of the inner bottom of the outer barrel 1;

[0040] The exhaust middle cylinder 202 is arranged at the center of the cylinder 201;

[0041] The spiral blade 203 has an inner circumference fixed to the circumference of the exhaust middle cylinder 202 and an outer circumference fixed to the inner wall of the cylinder 201;

[0042] The lower plate 204 has a through hole at its center and is fixed to the top of the barrel 201;

[0043] The upper plate 205 is located on the top of the lower plate 204 and is fixed to the outer barrel 1;

[0044] A lower discharge pipe 206 connected to the lower plate 204;

[0045] The upper row of pipes 207 penetrates the lower plate 204 and is connected to the upper plate 205;

[0046] The oil inlet pipe 208 is connected to the barrel 201 and is located above the spiral blade 203 .

[0047] When in use, after the gas-containing oil enters the barrel 201 through the oil inlet pipe 208, based on its own weight, the oil will fall along the spiral path of the spiral blade 203, and due to the centrifugal force generated by the spiral blade 203, the oil will be quickly separated from the gas and fall to the bottom of the barrel 201 along with the spiral blade 203.

[0048] For example, Figure 3 As shown, the utility model also includes that the bottom outlet end of the exhaust middle cylinder 202 is connected with a conical filter 209, the outer periphery of the cylinder 201 is provided with a round bucket-shaped mesh cover 210, the inner periphery of the round bucket-shaped mesh cover 210 is fixed to the cylinder 201, and the outer periphery of the round bucket-shaped mesh cover 210 is fixed to the outer barrel 1.

[0049] When in use, the gas entering the exhaust middle cylinder 202 is filtered by the conical filter 209 to achieve further oil screening.

[0050] For example, Figure 3 As shown, the utility model also includes that the air outlet end of the lower pipe 206 is located at the bottom of the round bucket-shaped mesh cover 210, and the air inlet end of the upper pipe 207 is located at the top of the round bucket-shaped mesh cover 210.

[0051] When in use, the gas entering the upper plate 205 is filtered and filtered for oil twice through the round bucket-shaped mesh cover 210 .

[0052] For example, Figure 1 , 3 As shown, the utility model also includes that the air inlet end of the vacuum pump 3 is connected to an air inlet pipe 4, the air inlet pipe 4 is connected to the outer barrel 1, and the air inlet end of the air inlet pipe 4 is located at the top of the upper plate 205.

[0053] For example, Figure 1 As shown, the utility model also includes that the bottom of the outer barrel 1 and the bottom of the round barrel 201 are respectively connected with oil drain joints 5.

[0054] The oil discharge joint 5 is equipped with a one-way valve.

The vacuum pump 3 evacuates the air inlet pipe 4, so that a certain negative pressure is formed in the outer barrel 1 and at the top of the upper plate 205. Through the setting of the upper discharge pipe 207, a negative pressure environment is formed at the outer bottom of the spiral part 2 and the inside of the exhaust middle cylinder 202. After the gas-containing oil enters the barrel 201 through the oil inlet pipe 208, Based on the dead weight of the oil, the oil will fall along the spiral path of the spiral blade 203, and the centrifugal force generated by the spiral blade 203 will quickly separate the oil from the gas. As the spiral blade 203 falls to the bottom of the drum 201, due to the negative pressure inside the exhaust middle cylinder 202, the gas separated from the oil will be filtered by the conical filter 209, pass through the top of the lower plate 204, and enter the lower discharge pipe 206, and then pass through the round bucket-shaped mesh cover 210 for secondary filtration, enter the top of the upper plate 205, and be discharged from the air inlet pipe 4, so that the vacuum pump 3 pumps the gas to the gas collection equipment or pipeline to complete the oil and gas separation.
