Description

Technical Field

[0001] The utility model relates to the technical field of oil separators, in particular to an oil separator. Background Art

[0002] The oil separator is a device that separates the crude oil and associated natural gas produced by the oil well. It is a key component that determines the quality of compressed air in the air compressor. The existing oil separators mainly include centrifugal oil separators, washing separators and filtering oil separators.

[0003] At present, a Chinese utility model with a publication number of CN202628065U discloses an oil separator, including a separator body, wherein an air inlet and an air outlet are provided at the top of the separator body, an oil return port is provided at the bottom of the separator body, an oil return pipe is provided on the oil return port, a filter device is provided in the separator body, the filter device is spirally arranged in the separator body, and a side flow isolation device is provided on the outside of the filter device.

[0004] The existing utility model spirally sets the filter device in the separator body to improve the separation efficiency. However, when the filter device is spirally set in the separator body, the oil stains adhering to the upper filter device will drip onto the lower filter device due to gravity, thereby affecting the filtering effect of the bottom filter device, and when the filtering effect of the filter device weakens, the entire filter device needs to be replaced, which greatly increases the cost of use and needs to be improved. Utility Model Content

[0005] The utility model aims to provide an oil separator, which has the advantages of simple structure, high separation and filtration efficiency, good separation effect and low replacement cost.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: an oil separator, including a separation tank body, a side wall of the separation tank body is fixedly provided with an input port for inputting oil-containing medium, and the top of the separation tank body is provided with an output port; the separation tank body is fixedly provided with a first porous plate at the upper part of the input port, and a second porous plate is fixedly provided at the lower part of the input port, a baffle for connecting the first porous plate and the second porous plate is fixedly provided on the input port, and the separation tank body is respectively provided with a first filter element assembly and a second filter element assembly along the vertical direction on the top of the first porous plate.

[0007] The utility model is further configured as follows: the first porous plate is configured to be inclined upward.

[0008] The utility model is further configured as follows: a drip tray for collecting oil condensed and dripping from the first porous plate is fixedly provided at the bottom of the first porous plate so that the oil on the first porous plate can be quickly condensed and dropped to the bottom of the separation tank body.

[0009] The utility model is further configured as follows: the second porous plate is arranged near the bottom of the separation tank body so as to prevent the oil-carrying medium from entering from the input port and contacting the oil deposited at the bottom of the separation tank body, thereby reducing the filtering efficiency.

[0010] The utility model is further configured as follows: the first filter element assembly is arranged along a vertical direction, and the second filter element assembly is arranged along a horizontal direction.

[0011] The utility model is further configured as follows: a viewing mirror is arranged at one end of the bottom of the separation tank body away from the input port, and a U-shaped baffle is fixedly arranged in the separation tank body for preventing the viewing mirror from being impacted by gas so as to extend the service life of the viewing mirror.

[0012] The utility model is further configured as follows: the first porous plate is evenly provided with a plurality of evenly distributed holes for evenly distributing the gas flow and reducing the gas flow rate so as to enhance the subsequent separation effect.

[0013] In summary, the utility model has the following beneficial effects:

[0014] 1. By arranging a first porous plate at the upper part of the input port and arranging a number of evenly distributed holes on the first porous plate, the oil-containing medium can evenly divide the gas flow and reduce the gas flow rate when passing through, and at the same time, the oil and impurities in the oil-containing medium are filtered for the first time. After the flow rate is reduced, the medium is evenly divided and passes through the second filter component and the first filter component in sequence, thereby enhancing the separation effect and improving the separation efficiency. At the same time, the first porous plate, the first filter element component and the second filter element component are respectively arranged in the limited space of the separation tank body, the porous plate performs the first separation on the oil-containing medium, and the first filter element component and the second filter element component perform the second and third separation on the oil-containing medium, and the separation efficiency and separation effect of the oil separator are improved through multiple filtrations;

[0015] 2. The first porous plate is tilted and a drip tray is provided at the bottom. The oil after preliminary filtration is condensed on the first porous plate. Due to the effect of gravity, the oil on the first porous plate drips into the drip tray for collection, so that the oil on the first porous plate can be quickly condensed and collected at the bottom of the container, avoiding too much condensed oil on the first porous plate to affect the efficiency of gas passage and the effect of initial separation. At the same time, the first porous plate, the baffle, the second porous plate and the U-shaped baffle form a closed space. The oil-containing medium directly passes through the first separation plate from the input port and enters the subsequent first filter element assembly and the second filter element assembly, avoiding the oil-containing medium from affecting each other in the separation tank body and reducing the separation effect. The second porous plate is set close to the bottom of the separation tank body, so that the medium will not directly contact the oil precipitated at the bottom after entering, and will not reduce the subsequent filtration efficiency.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0020] Example:

[0021] refer to Figure 1 to Figure 2 An oil separator comprises a separation tank body 1 arranged along a vertical direction, an input port 11 for inputting an oil-containing medium is fixedly provided on the side wall of the separation tank body 1, an output port 12 is opened on the top of the separation tank body 1, a first porous plate 2 is fixedly provided on the upper part of the input port 11 of the separation tank body 1, a plurality of uniformly distributed holes for evenly dividing the gas flow and reducing the gas flow rate so as to enhance the subsequent separation effect are evenly opened on the first porous plate 2, a second porous plate 3 is fixedly provided on the lower part of the input port 11, a baffle 4 for connecting the first porous plate 2 and the second porous plate 3 is fixedly provided on the input port 11, a first filter element assembly 5 and a second filter element assembly 6 are respectively provided on the top of the first porous plate 2 of the separation tank body 1 along the vertical direction, and a filter element assembly 6 is provided on the upper part of the first porous plate 2 of the separation tank body 1 by A first porous plate 2 is arranged on the upper part of the input port 11 and a plurality of evenly distributed holes are arranged on the first porous plate 2. When the oil-containing medium passes through, the gas flow rate can be evenly divided and the gas flow rate can be reduced. At the same time, the oil and impurities in the oil-containing medium are filtered for the first time. After the flow rate is reduced, the medium is evenly divided and passes through the second filter component and the second filter component in turn, thereby enhancing the separation effect and improving the separation efficiency. At the same time, the first porous plate 2, the first filter element component 5 and the second filter element component 6 are respectively arranged in the limited space of the separation tank body 1. The porous plate performs the first separation on the oil-containing medium, and the first filter element component 5 and the second filter element component 6 perform the second and third separations on the oil-containing medium. Through multiple filtrations, the separation efficiency and separation effect of the oil separator are improved.

[0022] refer to Figure 2Specifically, the first porous plate 2 is tilted upward, and a drip tray 7 is fixed at the bottom of the first porous plate 2 for collecting the oil condensed and dripping from the first porous plate 2 so that the oil on the first porous plate 2 can quickly condense and drop to the bottom of the separation tank body 1. The oil that has been initially filtered condenses on the first porous plate 2, and due to the effect of gravity, the oil on the first porous plate 2 drops into the drip tray 7 for collection, so that the oil on the first porous plate 2 can quickly condense and be collected at the bottom of the container, thereby avoiding too much condensed oil on the first porous plate 2 to affect the efficiency of gas passage and the effect of initial separation. The second porous plate 3 is set at a position close to the bottom of the separation tank body 1 to avoid the oil-containing medium from entering from the input port 11 and contacting the oil deposited at the bottom of the separation tank body 1, thereby reducing the filtration efficiency.

[0023] refer to Figure 1 Specifically, the first filter element assembly 5 is arranged along the vertical direction, and the second filter element assembly 6 is arranged along the horizontal direction. The medium preliminarily filtered by the first porous plate 2 first passes through the second filter element assembly 6. The second filter element assembly 6 is arranged along the horizontal direction to increase the contact area with the medium and thus increase the effect of the secondary filtration. The first filter element assembly 5 is arranged along the vertical direction to reduce the oil content adhering to each first filter element assembly 5 while performing three filtrations, thereby increasing the service life of the first filter element assembly 5 and reducing the cost of filter element replacement.

[0024] refer to Figure 1 Specifically, a sight glass 8 for observation is provided at one end of the bottom of the separation tank body 1 away from the input port 11, and a U-shaped baffle 9 is fixedly provided in the separation tank body 1 for preventing the sight glass 8 from being impacted by gas and thus extending the service life of the sight glass 8.

[0025] Brief description of the use process: the oil-containing medium enters from the input port 11 and passes through the first porous plate 2 to evenly divide the airflow and reduce the gas flow rate. At the same time, the oil and impurities in the oil-containing medium are filtered for the first time. After the flow rate is reduced, the medium is evenly divided and then passes through the second filter component and the first filter component in turn to perform secondary and tertiary filtration. The oil that has been initially filtered condenses on the first porous plate 2. Due to the effect of gravity, the oil on the first porous plate 2 drops into the drip tray 7 for collection, so that the oil on the first porous plate 2 can be quickly condensed and collected at the bottom of the container, avoiding too much condensed oil on the first porous plate 2 to affect the efficiency of gas passage and the effect of initial separation.
