Description

Technical Field

[0001] The invention belongs to the technical field of oil-gas separation, and in particular relates to an oil-gas separation device. Background Art

[0002] The oil-gas separation device is mainly used for oil-gas separation, so that the oil-gas mixture can complete the oil-gas two-phase separation, so that the gas contains less liquid and the liquid contains less gas. Oil-gas separation devices are usually divided into vertical and horizontal structures based on gravity separation. However, the horizontal structure usually occupies a large area and has certain limitations in use. The traditional vertical structure is based on the collision separation principle. The collision separation principle means that the airflow changes its flow direction and speed when encountering an obstacle, so that the droplets in the gas continue to coalesce at the obstacle. Due to the surface tension of the droplets, an oil film is formed. The gas continuously contacts and coalesces the small oil droplets into large oil droplets, which settle down by gravity, thereby achieving the purpose of separating the oil-gas mixture. However, there are the following defects in the oil-gas separation process:

[0003] During the circulation of oil and gas, the contact area between the oil and gas and the cold source and collision obstacles is small, which may result in a small probability of internal gas contact between the oil and gas, making it difficult to separate the internal oil molecules, resulting in poor oil and gas separation effect.

Meanwhile, a rotating ball is arranged under the convex arc plate at the bottom, so that the surface temperature of the convex arc plate and the rotating ball is relatively low.

An auxiliary condensation unit 406 is arranged below the fixed pipe 403, through which oil and gas continuously pass through the inner side of the raised annular wall 401. Since the temperature of the raised arc plate 404 is relatively low under the action of cooling water, the oil and gas are cooled and condensed. At the same time, the shape of the raised arc plate 404 increases the contact area, thereby improving the condensation effect.

[0033] The auxiliary condensation unit 406 includes a rotating ball 4064 arranged below the fixed pipe 403, the top wall of the rotating ball 4064 is in close contact with the bottom wall of the lowest raised arc plate 404, and the rotating ball 4064 and the raised arc plate 404 are used to increase the contact surface between the cold source and the oil and gas.

The rotating ball 4064 is rotatably installed inside the spherical groove 4062, and a flow gap 4066 is formed between the outer wall of the rotating ball 4064 and the inner wall of the spherical groove 4062. The top and bottom ends of the spherical groove 4062 are provided with end grooves 4063. The fixed pipe 403 and the bottom block 4061 are provided with a cooling flow unit 407.

The inner wall of the arc groove is in close contact with the bottom wall of the rotating ball 4064. The lowest raised arc plate 404 is in close contact with the top wall of the rotating ball 4064, so that the surface of the rotating ball 4064 is in a low temperature state. At the same time, the condensation area is further increased by the rotating ball 4064, and the scraper 4067 can scrape the oil on the surface of the rotating ball 4064, and at the same time make the surface without oil adhesion contact with oil and gas, thereby improving the oil and gas separation effect.

[0034] A raised annular wall 401 is provided on the inner wall of the separation tower 1, and the raised annular wall 401 is provided close to the edge of the raised arc plate 404. Bell mouths 402 are symmetrically provided at the upper and lower ends of the raised annular wall 401, and the diameter of the bell mouth 402 at one end close to the raised annular wall 401 is smaller than the diameter of the bell mouth 402 at the other end away from the raised annular wall 401.

[0035] The cooling circulation unit 407 includes two end communication grooves 4073 opened inside the bottom block 4061, and a circulation arc groove 4072 is opened at an equal angle between the upper and lower end communication grooves 4073. The circulation arc groove 4072 is set at an equal angle outside the circulation gap 4066. A circulation cavity 4071 is opened inside the fixed pipe 403, and connecting pipes 4074 are symmetrically installed on both sides of the bottom of the circulation cavity 4071. One end of the connecting pipe 4074 is connected to the upper end communication groove 4073, and the bottom end of the lower end communication groove 4073 is opened with a pipe fitting connection. The through groove 4075, the bottom end of the pipe connecting groove 4075 is connected to a return pipe 4076, and a cooling box is installed between one end of the return pipe 4076 and the top of the circulation cavity 4071. When the cooling water circulates, it continuously flows through the circulation arc groove 4072, and the circulation arc groove 4072 is located on the outside of the circulation gap 4066 between the inner wall of the spherical groove 4062 and the outer wall of the rotating ball 4064, so that the temperature in the circulation gap 4066 is lower, and because the circulation gap 4066 is narrow, the cooling effect on the oil and gas is better, further improving the condensation effect.

[0036] The top air inlet assembly 2 includes a top tube 201 installed on the top of the separation tower 1, a longitudinal tube 202 is installed on the top of the top tube 201, a transverse tube 203 is installed on one side of the longitudinal tube 202, the top of the fixed tube 403 passes through the top of the longitudinal tube 202, an upper rotating ring 204 is rotatably installed on the outer side of the fixed tube 403, a bottom plate 205 is installed on the top of the upper rotating ring 204, a rotating sleeve 207 is installed on the top of the bottom plate 205, and the rotating sleeve 207 is sleeved on the outer side of the fixed tube 403, a top plate 206 is arranged above the bottom plate 205, impeller blades 208 are installed at equal angles inside the bottom plate 205 and the top plate 206, and an air inlet groove 209 is opened at equal angles on the bottom plate 205.

[0037] The bottom storage assembly 3 includes a bottom box 301 fixedly installed at the bottom end of the separation tower 1, an exhaust hole 302 is opened at an equal angle on the top of the bottom box 301, a drain pipe 303 is installed at the bottom end of the bottom box 301, a valve is installed on the drain pipe 303, a lower rotating ring 304 is rotatably installed inside the bottom box 301, a knock-off plate 305 is installed at an equal angle on the inner side of the lower rotating ring 304, a connecting assembly 5 is arranged between the lower rotating ring 304 and the upper rotating ring 204, and an exhaust control assembly 6 is arranged above the exhaust hole 302.

[0038] The connecting component 5 includes tooth grooves 501 opened at equal angles on the outer side of the upper rotating ring 204 and the outer side of the lower rotating ring 304. One side of the upper rotating ring 204 and one side of the lower rotating ring 304 are meshed and connected with a gear set 502. The upper and lower gear sets 502 are connected by a rotating shaft 503, and the top of the rotating shaft 503 is fixedly connected to the output shaft of the second motor 504. The gear set 502 is rotatably installed on the mounting frame. The two mounting frames are respectively installed on the side walls of the top tube 201 and the side walls of the bottom box 301, and the second motor 504 is fixedly installed on the mounting frame.

[0039] The exhaust control component 6 includes an annular box 601 fixedly installed on the top of the bottom box 301, the annular box 601 is connected to each exhaust hole 302, an exhaust main pipe 602 is installed on the top of the annular box 601, a concentration detection sensor is installed inside the exhaust main pipe 602, a return pipe 603 is installed on one side of the exhaust main pipe 602, an exhaust branch pipe 604 is installed on the top of the exhaust main pipe 602, and electric ball valves are installed on the return pipe 603 and the exhaust branch pipe 604. When the treated oil and gas are discharged from the exhaust hole 302, they enter the annular box 601 and are discharged from the exhaust main pipe 602. When flowing through the exhaust main pipe 602, a concentration detection sensor is arranged inside the exhaust main pipe 602 to detect the concentration of oil molecules in the discharged oil and gas. When the concentration of oil molecules is high, the staff controls the electric ball valve on the return pipe 603 to open, so that the oil and gas are refluxed and condensed again. When the concentration of oil molecules is low, the staff controls the electric ball valve on the exhaust branch pipe 604 to open and discharge directly.

[0040] Working principle: When working, first connect the cooling water tank between the top of the circulation cavity 4071 and the end of the return pipe 4076. Driven by the water pump, the cooling water can circulate inside the circulation cavity 4071, the connecting pipe 4074, the end connecting groove 4073, and the circulation arc groove 4072.

[0041] Then, the second motor 504 is turned on to rotate the rotating shaft 503, and then the upper rotating ring 204 and the lower rotating ring 304 are driven to rotate continuously through the upper and lower gear sets 502;

[0042] After the upper rotating ring 204 drives the impeller blades 208 to rotate continuously, the air is driven to circulate continuously, thereby driving the oil and gas from the transverse tube 203 into the top tube 201, and then evenly passes through the air inlet groove 209 to enter the inner side of the raised ring wall 401. Since the rotating sleeve 207 is sleeved on the outer side of the fixed tube 403, and the temperature of the fixed tube 403 is relatively low under the action of cooling water, when the oil and gas evenly pass through the air inlet groove 209, the temperature drops, causing some oil molecules in the oil and gas to liquefy into droplets, and the droplets drip downward;

[0043] When the oil and gas continuously pass through the inner side of the raised annular wall 401, the raised arc plates 404 are equidistantly installed on the outer side of the fixed pipe 403, and the raised arc plates 404 have a lower temperature under the action of cooling water. When the oil and gas continuously pass through the raised arc plates 404, the top wall of the raised arc plates 404 bulges upward, thereby increasing the contact area between the oil and gas and the surface of the raised arc plates 404, so that the oil molecules in the oil and gas contact with the raised arc plates 404 and are liquefied, which facilitates the separation of the oil and gas.

[0044] At the same time, the lowermost raised arc plate 404 is in close contact with the top wall of the rotating ball 4064, so that the surface of the rotating ball 4064 is in a low temperature state. The rotating ball 4064 is set in a spherical shape, which further increases the contact area between the oil and gas and the cold source. At the same time, during the continuous rotation of the rotating ball 4064, the scraper 4067 scrapes the oil on the surface of the rotating ball 4064, and at the same time makes the surface without oil adherence contact with the oil and gas, so as to improve the oil and gas separation effect. After the oil and gas contact the top wall of the rotating ball 4064, they flow downward along the flow gap 4066 between the inner wall of the spherical groove 4062 and the outer wall of the rotating ball 4064, and the cooling water continuously passes through the flow arc groove 4072 outside the flow gap 4066. Since the oil and gas airflow is dispersed in the flow gap 4066, the contact effect between the oil molecules inside the oil and gas and the cold source is improved, and the oil and gas separation effect is improved;

[0045] Since the top walls of the raised arc plate 404 and the rotating ball 4064 are both raised, it is convenient for the liquefied oil to flow into the bottom box 301. At the same time, the lower rotating ring 304 rotates continuously to allow the knocking plate 305 to discharge the oil and oil droplets entering the bottom box 301, preventing the oil droplets from being re-discharged with the gas. Finally, the remaining gas is discharged from the exhaust hole 302. During the discharge process, the oil and gas concentration in the gas is detected and subsequent operations are performed.
