Description

Technical Field

[0001] The present invention relates to the technical field of fuel gas-liquid separation, and in particular to a gas-liquid separation device and a separation method for fuel production. Background Art

[0002] The gas-liquid separation device for fuel production plays a key role in the fuel production process. Its main purpose is to effectively separate substances of different phases in the fuel mixture to ensure the purity and quality of the fuel.

[0003] The Chinese patent with the announcement number CN207786027U discloses a horizontal three-phase separator, including a horizontal tank body, an inlet pipe is arranged at the top of the inlet end of the horizontal tank body, an air outlet pipe is arranged at the top of the outlet end, and a water outlet pipe and an oil outlet pipe are arranged at the bottom, a rectifying orifice plate, an overflow plate, and a solid impurity baffle are arranged in the inner cavity of the horizontal tank body, a solid impurity discharge pipe is arranged at the bottom of the horizontal tank body between the rectifying orifice plate and the solid impurity baffle, a valve is arranged on the solid impurity discharge pipe, a solid impurity storage tank is arranged below the horizontal tank body, and the bottom of the solid impurity discharge pipe is connected to the top of the solid impurity storage tank. The part of the inner cavity of the horizontal tank body between the rectifying orifice plate and the inlet end cap is a buffer zone, the part between the rectifying orifice plate and the overflow plate is a separation zone, and the part between the overflow plate and the outlet end cap is an oil tank.

[0004] In the separation process of the above technical solution, the gas-liquid mixed fluid enters the buffer zone through the inlet pipe, and then enters the separation zone from the rectifying holes on the rectifying orifice plate for separation. The separated gas phase flows out through the outlet pipe, the water flows out from the water outlet pipe, and the oil phase overflows from the top of the overflow plate into the oil tank and then flows out through the oil outlet pipe. However, in the separation process of the above technical solution, the liquid mist droplets carried in the gas cannot be effectively separated. In the related technology, a mist collector is set at the inlet of the outlet pipe to filter the mist droplets contained in the gas, but the mist collector can only play a better filtering and separation role when the liquid content in the gas is small. When processing gas with a high liquid content, more droplets will be attached to the mist collector, increasing the resistance of the gas passing through, affecting the filtering efficiency, and the attached droplets will reduce the actual available capture area, clogging the capture pores, etc., resulting in poor filtering effect of the mist collector and unsatisfactory gas-liquid separation effect. In addition, the above technical solution cannot perform gas-liquid separation on the fuel gas mixture and has poor applicability.

[0005] Therefore, the art needs a gas-liquid separation device and separation method for fuel production to solve the above problems. Summary of the invention

[0006] The present invention provides a gas-liquid separation device and separation method for fuel production, aiming to solve the problem that the gas-liquid separation device in the related art has poor separation effect when the liquid content in the gas is high and cannot perform gas-liquid separation on the fuel gas mixture.

[0007] On the one hand, the present invention provides a gas-liquid separation device for fuel production, comprising a tank body and an overflow baffle disposed in the tank body, wherein a feed inlet, an oil outlet, a liquid outlet and a gas outlet are provided on the tank body, a mist collector is provided at the gas outlet, the axial direction of the tank body is defined as the left-right direction, a plurality of guide plates 1 evenly spaced along the left-right direction are provided between the feed inlet and the gas outlet, a stop plate is vertically inserted at the top of the guide plate 1, the stop plate is elastically connected to the guide plate 1 through an elastic member, and adjacent stop plates are fixedly connected through a connecting rod;

[0008] The tops of the guide plates 1 at the left and right ends are fitted with the tank body, and the vertical distances between the bottoms of the multiple guide plates 1 and the bottom of the tank body decrease from right to left. A guide plate 2 is arranged between two adjacent guide plates 1, and the guide plate 2 is rotatably connected to the tank body, and the position of the rotatable connection gradually decreases from right to left. A push structure is arranged between the guide plate 2 and the connecting rod, and a driving member for driving the guide plate 2 to rotate is arranged on the tank body;

[0009] When the guide plate 2 is in a vertical state, the connecting rod is pushed by the pushing structure to drive the stop plate to fit with the top of the tank body, and the guide plate 1 and the guide plate 2 form a serpentine channel 1. When the guide plate 2 rotates to overlap each other, a guide layer gradually rising from left to right is formed, and the elastic member drives the stop plate to separate from the tank body, and a serpentine channel 2 is formed between the guide plates 1.

[0010] Beneficial effect: The present invention forms a serpentine channel one through guide plates one and two. When processing a fuel-gas mixture, the flow path of the fuel-gas mixture in the tank body can be extended, and the contact area and time of the fuel-gas mixture with guide plates one and two can be increased. Liquid mist droplets in the fuel-gas mixture hit the surfaces of guide plates one and two under the action of inertial force, and are captured by guide plates one and two, thereby realizing gas-liquid separation of the fuel-gas mixture; the present invention forms a guide layer through guide plate two, and a serpentine channel two is formed between guide plates one. When processing an oil-gas-water mixture, the mixed gas in the mixture can rise and flow along the guide layer to the entrance of serpentine channel two, so that the gas moves along serpentine channel two, thereby capturing the liquid mist droplets in the gas on the surface of guide plate one, thereby realizing gas-liquid separation in the oil-gas-water mixture, thereby improving the applicability of the present invention, and improving the problem that when the content of liquid mist droplets in the gas is high, it is impossible to achieve good separation only by a mist catcher, thereby improving the separation effect of the gas-liquid mixture.

[0011] Preferably, the pushing structure includes a pushing plate in an inverted trapezoidal shape, which is fixedly connected to the connecting rod, and the two bottom corners of the pushing plate are set as rounded corners. The end of the guide plate 2 that contacts the pushing plate is provided with an arc surface. When the arc surface of the guide plate 2 contacts the inclined surface of the pushing plate, the pushing plate is driven to move upward by pushing the inclined surface of the pushing plate.

[0012] Preferably, a knocking rod is vertically slidably connected inside the guide plate one, the bottom end of the knocking rod passes through the guide plate one and is fixedly connected with a knocking head, and a driving component is provided inside the guide plate one to drive the knocking rod to move vertically so that the knocking head knocks the bottom of the guide plate one.

[0013] Beneficial effect: Since the liquid mist droplets in the gas-liquid mixture will continuously collide and stay on the guide plate one and the guide plate two, the wettability of the surface of the guide plate one and the guide plate two will be affected, and the liquid separation effect will be reduced. By setting a knocking rod and a knocking head, during operation, the knocking head is made to knock on the guide plate one, thereby accelerating the flow and separation of the liquid on the guide plate one, and improving the capture effect of the guide plate one on the liquid mist droplets.

[0014] Preferably, the knocking rod is elastically connected to the guide plate one along the vertical direction. When the knocking rod is not subjected to external force, the knocking head abuts against the bottom of the guide plate one. When the driving component drives the knocking rod to move downward to a preset position, the drive to the knocking rod is canceled, and the knocking rod moves upward under the action of the elastic force, and drives the knocking head to knock the bottom of the guide plate one.

[0015] Preferably, the driving assembly includes a guide groove and a sliding rod, the sliding rod is elastically connected and slidably cooperates with the corresponding stop plate in the horizontal direction, the guide groove is opened on the guide plate, and the sliding rod is fixedly connected with a guide block extending into the guide groove. When the stop plate moves downward, the sliding rod is driven to press the knocking rod downward. When the knocking rod moves downward to a preset position, the sliding rod is disengaged from the knocking rod, and the knocking rod moves upward to reset.

[0016] Beneficial effect: the movement of the knocking rod is driven by the movement of the stop plate, the structure is ingenious and compact, there is no need to add an additional driving source to drive the movement of the knocking rod, and the cost is saved.

[0017] Preferably, the guide groove includes a vertical section and an inclined section, the end of the sliding rod close to the knocking rod is fixedly connected to a pressing block, and the top of the knocking rod is fixedly connected to a fixed block, when the guide block moves downward along the vertical section, the sliding rod presses the fixed block downward through the pressing block, when the guide block moves to the lower end of the inclined section, the pressing block is out of contact with the fixed block, when the pressing block is located below the fixed block, the pressing block and the fixed block are respectively provided with inclined wedge surfaces on one side facing each other, when the pressing block moves upward until it contacts the inclined wedge surface of the fixed block, the inclined wedge surface pushes the pressing block to move in a direction away from the fixed block.

[0018] Preferably, a guide groove is provided on the right side of the guide plate 1 near the bottom, and the guide groove is inclined downward from the middle to the front and rear ends.

[0019] Beneficial effect: By setting the guide groove, the droplets gathered on the surface of the guide plate will enter the guide groove when flowing downward, flow along the guide groove in the forward and backward direction, and finally flow downward along the side wall of the tank to the bottom, avoiding the phenomenon that the droplets are dripping down from the bottom of the guide plate and are carried away by the airflow again.

[0020] Preferably, an inclined plate fixedly connected to the tank body is provided below the mist collector, and the inclined plate is inclined upward from the left end to the right end. When the guide plate 2 rotates to overlap each other, the guide plate 2 adjacent to the inclined plate overlaps the inclined plate.

[0021] Beneficial effect: The inclined plate and the second guide plate cooperate to form a guide layer to guide the flow of the rising gas, thereby preventing the gas from rising directly to the mist collector and being discharged from the gas outlet.

[0022] Preferably, a flow stabilizing baffle connected to the tank body is arranged between the feed port and the adjacent guide plate, a wave-breaking and bubble-eliminating device is arranged between the flow stabilizing baffle and the overflow baffle, the wave-breaking and bubble-eliminating device is installed at the bottom of the tank body, the air outlet is connected to an air outlet pipe, and a demister is arranged in the air outlet pipe.

[0023] On the other hand, the present invention also provides a gas-liquid separation method for fuel production, the gas-liquid separation method for fuel production uses the gas-liquid separation device for fuel production described in any one of the above preferred technical solutions, and the gas-liquid separation method for fuel production comprises the following steps:

[0024] The state of the guide plate 2 is adjusted according to the state of the fuel mixture. When the fuel mixture is a fuel-gas mixture, the guide plate 2 is driven to move to a vertical state by a driving member, and the fuel-gas mixture is passed into the tank body. The fuel-gas mixture flows from the serpentine channel 1 to the gas outlet. Liquid mist droplets in the fuel-gas mixture hit the guide plate 1 and the guide plate 2, and flow downward along the guide plate 1 and the guide plate 2, and gather at the bottom of the tank body.

[0025] When the fuel mixture is an oil-gas-water mixture, the guide plate 2 is driven by the driving member to rotate until it overlaps with each other, and the oil-gas-water mixture is passed into the tank body. The oil-gas-water mixture flows to the bottom of the tank body, and the mixed gas in the oil-gas-water mixture gathers upward and moves to the right side of the serpentine channel 2 under the guidance of the guide layer, and flows to the air outlet along the serpentine channel 2. The liquid mist droplets in the gas hit the side wall of the guide plate 1 and flow downward along the guide plate 1.

[0026] The beneficial effects of the gas-liquid separation method for fuel production are the same as the beneficial effects of the above-mentioned gas-liquid separation device for fuel production, and will not be repeated here.

[0027] The beneficial effects of the present invention are:

[0028] (1) The gas-liquid separation device for fuel production of the present invention can not only perform gas-liquid separation on oil-gas-water mixture, but also perform gas-liquid separation on fuel-gas mixture, thereby improving the applicability of the gas-liquid separation device for fuel production;

[0029] (2) The present invention forms a guide layer by overlapping the guide plate 2 and forms a serpentine channel 2 by the guide plate 1, thereby extending the residence time of the gas-liquid mixture in the tank body. In addition, the guide plate 1 can intercept and separate the liquid mist droplets, which is beneficial to improving the separation effect of the gas-liquid mixture and improving the problem that when the content of liquid mist droplets in the gas is high, it is impossible to achieve good separation only by the mist collector.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0042] like Figures 1 to 9 As shown, a gas-liquid separation device for fuel production of the present invention comprises a tank body 1 and an overflow baffle 11 arranged in the tank body 1. The axial direction of the tank body 1 is defined as the left-right direction. A feed port 12 is provided at the right end of the tank body 1, an oil outlet 13 and a liquid outlet 14 are provided at the bottom, and a gas outlet 15 is provided at the top. The liquid outlet 14 is located on the right side of the overflow baffle 11, the oil outlet 13 is located on the left side of the overflow baffle 11, and the gas outlet 15 is located on the right side of the overflow baffle 11. A flow stabilizing baffle 16 fixedly mounted on the tank body 1 is provided on the left side of the feed port 12, and a wave-proof bubble eliminator 17 is provided between the flow stabilizing baffle 16 and the overflow baffle 11. The wave-proof bubble eliminator 17 is installed at the bottom of the tank body 1. A mist catcher 18 fixedly mounted on the tank body 1 is provided below the gas outlet 15. The gas outlet 15 is connected to a gas outlet pipe 19, and a mist eliminator is provided in the gas outlet pipe 19.

[0043] Three guide plates 2 are arranged evenly spaced in the left-right direction between the feed port 12 and the gas outlet 15. The guide plates 2 are fixedly connected to the tank body 1, and the front and rear side walls of the guide plates 2 are respectively fitted with the inner wall of the tank body 1. The tops of the guide plates 2 at the left and right ends are fitted with the tank body 1. There is a gap between the top of the guide plate 2 in the middle and the top of the tank body 1. The vertical distances between the bottoms of the three guide plates 2 and the bottom of the tank body 1 decrease from right to left. A stop plate 3 is inserted vertically at the top of the guide plate 2, and the bottom of the stop plate 3 is elastically connected to the guide plate 2 through an elastic member. As an example, the elastic member is a spring 31. Adjacent stop plates 3 are fixedly connected by a connecting rod 4.

[0044] like Figure 2 and Figure 5As shown, a guide plate 2 5 is provided between two adjacent guide plates 1 2, the guide plate 2 5 is rotationally connected to the tank body 1, and the position of the rotational connection gradually decreases from right to left, and a driving member for driving the guide plate 2 5 to rotate is provided on the tank body 1. As an example, the driving member is a driving motor 51, the driving motor 51 is fixedly connected to the tank body 1, and the output end of the driving motor 51 is fixedly connected to the rotating shaft of the corresponding guide plate 2 5.

[0045] like Figure 2 and Figure 4 As shown, a push structure is provided between the guide plate 2 5 and the connecting rod 4, and the push structure includes a push plate 41 in an inverted trapezoidal shape, the top of the push plate 41 is fixedly connected to the connecting rod 4, and the two bottom corners of the push plate 41 are set as rounded corners. An arc surface 52 is provided at one end of the guide plate 2 5 that contacts the push plate 41.

[0046] When the guide plate 2 5 is in a vertical state, the arc surface 52 abuts against the bottom of the push plate 41, and the top of the stop plate 3 fits against the tank body 1 to block the gap between the top of the guide plate 1 2 and the tank body 1. The elastic part at the bottom of the stop plate 3 is in a stretched state, and the three guide plates 1 2 and the two guide plates 2 5 form a serpentine channel 1.

[0047] At this time, it is suitable to perform gas-liquid separation treatment on the fuel gas mixture, and the fuel gas mixture is introduced into the tank body 1, and the fuel gas mixture flows from the serpentine channel 1 to the gas outlet 15, and the liquid mist droplets in the fuel gas mixture hit the guide plate 1 2 and the guide plate 2 5, and flow downward along the guide plate 1 2 and the guide plate 2 5, gather at the bottom of the tank body 1, and are discharged from the liquid outlet 14. The gas flowing to the gas outlet 15 is discharged after being processed by the mist collector 18 and the demister.

[0048] When the guide plate 2 5 rotates counterclockwise from the vertical state to disengage from the push plate 41, the stop plate 3 moves downward under the elastic force of the elastic member, opening the gap between the top of the guide plate 1 2 in the middle and the tank body 1, and a serpentine channel 2 is formed between the guide plates 1 2. An inclined plate 10 fixedly connected to the tank body 1 is arranged below the mist catcher 18, and the inclined plate 10 is arranged upwardly inclined from the left end to the right end. When the guide plates 2 5 continue to rotate counterclockwise to overlap each other, the guide plate 2 5 on the left overlaps the inclined plate 10, and the inclined plate 10 and the two guide plates 2 5 form a guide layer that gradually rises from left to right.

[0049] At this time, it is suitable to separate the oil-gas-water mixture, and the oil-gas-water mixture is introduced into the tank body 1, and the oil-gas-water mixture flows to the bottom of the tank body 1, the oil floats to the liquid surface, and overflows from the top of the overflow baffle 11 to the left side of the overflow baffle 11, and is discharged from the oil outlet 13, the water is deposited below the oil, and is discharged from the liquid outlet 14, the mixed gas in the oil-gas-water mixture gathers upward, and part of the gas close to the overflow baffle 11 moves upward from the gap between the inclined plate 10 and the overflow baffle 11, and is directly discharged after being treated by the mist collector 18, and most of the gas moves to the right side of the serpentine channel 2 under the guidance of the guide layer, and flows along the serpentine channel 2 to the gas outlet 15, the liquid mist droplets in the gas hit the side wall of the guide plate 2, and flow downward along the guide plate 2 to the top of the guide layer, and the liquid dripping onto the guide layer flows along the guide layer to the bottom of the tank body 1.

[0050] When the guide plate 2 5 rotates from the inclined state until the arc surface 52 contacts the inclined surface of the push plate 41, the push plate 41 is driven to move upward by squeezing the inclined surface of the push plate 41 until the arc surface 52 moves to the bottom of the push plate 41, and the guide plate 2 5 moves to the vertical state.

[0051] like Figure 2 , Figures 5 to 7 As shown, since the liquid mist droplets in the gas-liquid mixture will continuously hit and stay on the guide plate 1 and the guide plate 2 5, the wettability of the surface of the guide plate 1 and the guide plate 2 5 will be affected, and the liquid separation effect will be reduced. Therefore, in this embodiment, a knocking rod 6 is vertically slidably connected inside the guide plate 1 2, and the bottom end of the knocking rod 6 passes through the guide plate 1 2 and is fixedly connected with a knocking head 61. A driving component for driving the knocking rod 6 to move vertically is provided inside the guide plate 1 2, so that the knocking head 61 knocks the bottom of the guide plate 1 2, causing the guide plate 1 2 to vibrate, and accelerating the separation of the liquid on the guide plate 2 2. The separation of the liquid on the guide plate 2 5 can be achieved by driving the guide plate 2 5 to rotate by the driving motor 51, changing the inclination angle of the guide plate 2 5, and causing the liquid attached to the guide plate 2 5 to flow rapidly.

[0052] Three knocking rods 6 are arranged in each guide plate 2 at intervals along the front-to-back direction. The knocking rods 6 are elastically connected to the corresponding guide plate 2 along the vertical direction through springs 62. When the knocking rods 6 are not subjected to external force, the knocking heads 61 abut against the bottom of the guide plate 2.

[0053] The driving assembly includes a guide groove 8 and a sliding rod 7. A mounting rod 32 extends from the bottom of the stop plate 3. The sliding rod 7 is slidably connected to the corresponding mounting rod 32 along the front-back direction, and a pressing block 71 is fixedly connected to one end of the sliding rod 7 close to the knocking rod 6. A spring 72 is connected between the pressing block 71 and the mounting rod 32. The guide groove 8 is provided on the guide plate 1 2, and a guide block 73 extending into the guide groove 8 is fixedly connected to the sliding rod 7. A fixed block 63 is fixedly connected to the top of the knocking rod 6. When the top of the stop plate 3 fits the top of the tank body 1, the sliding rod 7 is located above the knocking rod 6, and the pressing block 71 is located above the fixed block 63.

[0054] The guide groove 8 includes a vertical section 81 and an inclined section 82. When the stop plate 3 moves downward, it drives the sliding rod 7 to move downward, and the guide block 73 moves along the guide groove 8. The pressing block 71 drives the knocking rod 6 to move downward by squeezing the fixed block 63. When the guide block 73 moves along the vertical section 81 of the guide groove 8 to the inclined section 82, the groove wall of the inclined section 82 squeezes the guide block 73 to drive the sliding rod 7 to move away from the knocking rod 6. When the guide block 73 moves to the lower end of the inclined section 82, the pressing block 71 disengages from the fixed block 63, and the knocking rod 6 moves upward and resets under the elastic force of the spring 2 62, and the knocking head 61 at the bottom end of the knocking rod 6 knocks on the bottom of the guide plate 2.

[0055] When the pressing block 71 is located below the fixed block 63, the pressing block 71 and the fixed block 63 are respectively provided with an inclined wedge surface 64 on the side facing each other. When the stop plate 3 moves upward, the sliding rod 7 is driven to move upward. When the inclined wedge surface 64 on the pressing block 71 contacts the inclined wedge surface 64 on the fixed block 63, the inclined wedge surface 64 on the fixed block 63 pushes the pressing block 71 to move away from the fixed block 63, and the spring three 72 between the pressing block 71 and the mounting rod 32 is compressed. After the pressing block 71 passes over the fixed block 63, the pressing block 71 is reset under the elastic force of the spring three 72.

[0056] like Figure 3 and Fig. 9 As shown, when the gas-liquid mixture flows toward the gas outlet 15 through the serpentine channel 1 and the serpentine channel 2, the gas may re-carry the liquid droplets flowing down from the side wall of the guide plate 2. Therefore, in this embodiment, a guide groove 9 is provided on the right side of the guide plate 2 near the bottom, and the guide groove 9 is tilted downward from the middle to the front and rear ends. When the liquid droplets gathered on the surface of the guide plate 2 flow downward, they will enter the guide groove 9, flow in the front and rear directions along the guide groove 9, and finally flow downward along the side wall of the tank body 1 to the bottom, avoiding the phenomenon that the liquid droplets are re-carried away by the airflow when dripping down from the bottom of the guide plate 2.

[0057] A gas-liquid separation method for fuel production, using the gas-liquid separation device for fuel production in the above embodiment, the gas-liquid separation method for fuel production comprises the following steps:

[0058] The state of the guide plate 2 5 is adjusted according to the state of the fuel mixture. When the fuel mixture is a fuel-gas mixture, the guide plate 2 5 is driven to rotate to a vertical state by the driving motor 51, and the guide plate 1 2 and the guide plate 2 5 form a serpentine channel 1;

[0059] The fuel-gas mixture is introduced into the tank body 1, and the fuel-gas mixture flows from the serpentine channel 1 to the gas outlet 15, and the liquid mist droplets in the fuel-gas mixture hit the guide plate 1 2 and the guide plate 2 5, and flow downward along the guide plate 1 2 and the guide plate 2 5, and gather at the bottom of the tank body 1;

[0060] During operation, at every preset time interval, the guide plate 2 5 is driven by the driving motor 51 to rotate clockwise until it is separated from the pushing plate 41, so that the liquid droplets gathered on the right side of the guide plate 2 5 fall quickly, and at the same time, the stop plate 3 loses the pushing, and the stop plate 3 drives the sliding rod 7 to press the knocking rod 6 downward. After the knocking rod 6 is separated from the sliding rod, the knocking head 61 knocks the guide plate 1 2, accelerating the falling of the liquid droplets on the right side of the guide plate 1 2, and then drives the guide plate 2 5 to rotate counterclockwise to return to the vertical state;

[0061] The gas coming out of the serpentine channel 1 is discharged from the gas outlet pipe 19 after being processed by the mist catcher 18 and the demister, and the liquid gathered at the bottom of the tank body 1 is discharged from the liquid outlet 14;

[0062] When the fuel mixture is an oil-gas-water mixture, the guide plates 2 5 are driven counterclockwise by the driving motor 51 to overlap each other, the inclined plate 10 and the two guide plates 2 5 form a guide layer, and a serpentine channel 2 is formed between the guide plates 1 2;

[0063] The oil-gas-water mixture is introduced into the tank body 1, and the oil-gas-water mixture flows to the bottom of the tank body 1. The gas mixed in the oil-gas-water mixture gathers upward, and under the guidance of the guide layer, moves to the right side of the serpentine channel 2, and flows along the serpentine channel 2 to the gas outlet 15. The liquid mist droplets in the gas hit the side wall of the guide plate 1 2, and flow downward along the guide plate 2;

[0064] During operation, at each preset time interval, the guide plate 2 5 is driven by the driving motor 51 to rotate clockwise to a vertical state, and then rotated counterclockwise to an overlapping state, so that the stop plate 3 drives the sliding rod 7 to drive the knocking rod 6, so that the knocking head 61 knocks on the guide plate 1 2, accelerating the flow and shedding of the liquid on the guide plate 1 2;

[0065] The oil in the oil-gas-water mixture floats to the liquid surface and overflows from the top of the overflow baffle 11 to the left side of the overflow baffle 11 and is discharged from the oil outlet 13. The water is deposited under the oil and is discharged from the liquid outlet 14. The gas coming out of the serpentine channel 2 is processed by the mist collector 18 and the demister and then discharged from the gas outlet pipe 19.

[0066] The gas-liquid separation device for fuel production of the present invention can not only perform gas-liquid separation on oil-gas-water mixture, but also perform gas-liquid separation on fuel-gas mixture. The gas-liquid separation device for fuel production of the present invention has strong applicability.
