Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gas-liquid separation devices, specifically a low-temperature evaporation gas-liquid separation device. Background Technology
[0002] In low-temperature evaporation, steam is generated, and the evaporated gas carries liquid. Therefore, when the steam is discharged, the liquid carried in the steam is harmful. Thus, a gas-liquid separation process is required when the gas is discharged to prevent harmful liquid from being discharged along with the gas. Because of the difference in specific gravity between gas and liquid, when liquid and gas mix and flow together, if they encounter an obstruction, the gas will be deflected, while the liquid, due to inertia, will continue to have a forward velocity. The forward-moving liquid adheres to the obstruction wall and then, due to gravity, gathers and drips downwards.
[0003] However, existing low-temperature evaporation gas-liquid separation devices use a conical baffle with a diameter larger than the outlet pipe diameter. After the gas-liquid mixture passes through this baffle, it is deflected and enters the outlet pipe through the side space. However, some steam still passes directly through the side space without being deflected, which seriously affects the gas-liquid separation effect. Furthermore, the method of single-baffle collision adhesion is used. Since the subsequent rising force or flow force of the gas is less than the force when it first enters the equipment, the collision friction force is extremely weak. The liquid in the gas does not have a large inertial force to form an adhesive force, so the liquid in the gas cannot adhere and still flows directly with the gas. Even after deflection, it is difficult to ensure sufficient separation of the liquid, resulting in high humidity of the gas in the outlet pipe.
[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a low-temperature evaporation gas-liquid separation device. Utility Model Content
[0005] The purpose of this invention is to provide a low-temperature evaporation gas-liquid separation device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-temperature evaporation gas-liquid separation device, comprising a separation tank, an air inlet channel at the bottom of the separation tank, a top cover fixedly connected to the top of the separation tank by bolts, an exhaust pipe fixedly connected through the center of the surface of the top cover, a perforated mesh plate fixedly connected to the center of the outer surface of the exhaust pipe, a sealing cylinder fixedly connected to the lower surface of the perforated mesh plate, a collection bucket fixedly connected to the lower end of the inner opening of the sealing cylinder, a connecting ring fixedly connected to the edge of the lower surface of the sealing cylinder, and a guide cone fixedly connected to the lower end of the connecting ring.
[0007] Preferably, the lower end of the exhaust pipe is located inside the collection bucket, and the bottom end of the sealing cylinder is configured as an inclined surface sloping towards the center.
[0008] Preferably, the collection bucket has drainage channels extending through both the left and right sides of its surface, and the top cover is arc-shaped.
[0009] Preferably, the upper opening diameter of the guide cone is larger than the diameter of the connecting ring and the perforated mesh plate, and a valve pipe is fixedly connected to the bottom end of the guide cone.
[0010] Preferably, a crossbar is fixedly connected to the upper side of the inner surface of the exhaust tank, a guide rod is slidably provided through the middle of the surface of the crossbar, and a spring is sleeved on the upper surface of the crossbar and fixedly connected to the outer side of the guide rod.
[0011] Preferably, the upper ends of the guide rod and the spring are fixedly connected to the same sealing plate, and the lower end of the guide rod is fixedly connected to a limiting plate.
[0012] Preferably, the sealing plate is located on the upper side of the exhaust pipe, and the diameter of the sealing plate is the same as the outer diameter of the exhaust pipe, while the diameter of the limiting plate is larger than the diameter of the guide rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the arrangement of a top cover, exhaust pipe, perforated mesh plate, sealing cylinder, collection bucket, connecting ring and guide cone, achieves gas-liquid mixing by multiple deflections during gas-liquid separation, combined with liquid adhesion and capture, thereby blocking more liquid and maximizing the gas-liquid separation effect within a limited space. The gas-liquid separation efficiency is high, the gas-liquid separation is more thorough, and the working quality of gas-liquid separation is greatly improved. 2. This utility model, through the arrangement of a crossbeam, guide rod, spring, and sealing plate, allows the sealing plate to rise when dry gas is discharged from the exhaust pipe. This rise is caused by the gas pushing force, which in turn pulls the spring to extend and the guide rod to move upward. After the sealing plate rises, the exhaust pipe opens, ensuring that the gas can be discharged normally. When the device is not in use, the sealing plate slides steadily downward under its own weight using the guide rod, sealing the upper opening of the exhaust pipe. The spring pulls the sealing plate to close it stably, preventing the sealing plate from sliding freely and opening. This effectively seals the exhaust pipe opening, preventing dust from entering the equipment and causing pollution. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1-3 As shown, a low-temperature evaporation gas-liquid separation device includes a separation tank 1, an air inlet channel 2 at the bottom of the separation tank 1, a top cover 3 fixedly connected to the top of the separation tank 1 by bolts, an exhaust pipe 4 fixedly connected through the middle of the surface of the top cover 3, a perforated mesh plate 5 fixedly connected to the middle of the outer surface of the exhaust pipe 4, a sealing cylinder 6 fixedly connected to the lower surface of the perforated mesh plate 5, a collection bucket 7 fixedly connected to the lower end of the inner opening of the sealing cylinder 6, a connecting ring 8 fixedly connected to the edge of the lower surface of the sealing cylinder 6, and a guide cone 9 fixedly connected to the lower end of the connecting ring 8. The upper opening diameter of the guide cone 9 is larger than the diameter of the connecting ring 8 and the perforated mesh plate 5; the top cover 3 is designed as an arc shape; instruction manual attached. Figure 2 The arrows marked in the text indicate the direction of steam flow.
[0018] By adopting the above technical solution, the entire separation tank 1 is connected to the steam outlet of the evaporation equipment via the air inlet channel 2; The steam will be divided outwards at the inclined surface of the lower surface of the guide cone 9, and thus rise along the edge of the inner surface of the separator 1; Using the arc-shaped top cover 3, the steam will converge towards the center and first collide and rub against the exhaust pipe 4. Some of the liquid in the steam can adhere to the surface of the exhaust pipe 4, and the liquid will continuously converge and flow downward along the exhaust pipe 4. Under the flow restriction of the exhaust pipe 4, the steam will flow downward and penetrate the perforated mesh plate 5. When the steam penetrates the perforated mesh plate 5, it will rub and collide with the perforated mesh plate 5. The mesh strips of the perforated mesh plate 5 can adhere a large amount of liquid in the steam, so that the liquid gathers on the perforated mesh plate 5 and drips downward. Some of the steam is blocked by the perforated mesh plate 5 and flows to the surroundings, and then flows back downward. At this time, the steam flowing back downward is limited by the protruding part at the upper end of the guide cone 9, and then forms a swirling upward flow, thus completing a second repeated collision and friction, which can fully separate the steam and prevent some steam from escaping. The steam will eventually pass through the perforated mesh plate 5 and enter the sealing cylinder 6, where it will collide and rub against the inner wall of the sealing cylinder 6 to adhere to the liquid in the steam. At this point, the steam has undergone a multi-stage gas-liquid separation process of adhesion. The steam that finally enters the collection tank 7 will continue to collide and rub against the inner wall of the collection tank 7 to adhere to the remaining trace amount of liquid, thereby completely removing the liquid from the gas. After the dry gas gathers at the bottom of the collection tank 7, it is squeezed upward by the opposing collisions and rises through the exhaust pipe 4 to be discharged.
[0019] Furthermore, the lower end of the exhaust pipe 4 is located inside the collection bucket 7, and the bottom end of the sealing cylinder 6 is set as an inclined surface sloping towards the center.
[0020] By adopting the above technical solution, the bottom of the inclined surface of the sealing cylinder 6 increases the blocking area, improves the effect of blocking liquid, and also accelerates the rate at which liquid falls and accumulates.
[0021] Furthermore, drainage channels are provided on both the left and right sides of the surface of the collection bucket 7.
[0022] By adopting the above technical solution, the water collected inside the collection tank 7 can be discharged to the left and right sides through the drainage channel. Since it is located on the left and right sides and is filled with liquid, gas cannot pass through and will only continuously push the liquid out, while the air will only gather and rise to the center and be discharged through the exhaust pipe 4.
[0023] Furthermore, a valve pipe 10 is fixedly connected to the bottom end of the guide cone 9.
[0024] By adopting the above technical solution, the liquid discharged from the inside of the collection tank 7 is gathered inside the guide cone 9. After the top cover 3 is disassembled, the water can be completely discharged by opening the valve pipe 10.
[0025] Furthermore, a crossbeam 11 is fixedly connected to the upper side of the inner surface of the exhaust tank 4, and a guide rod 12 is slidably provided through the middle of the surface of the crossbeam 11. A spring 14 is sleeved on the upper surface of the crossbeam 11 and fixedly connected to the outer side of the guide rod 12. The upper ends of the guide rod 12 and the spring 14 are fixedly connected to the same sealing plate 15, and the lower end of the guide rod 12 is fixedly connected to a limiting plate 13. The sealing plate 15 is located on the upper side of the exhaust pipe 4, and the diameter of the sealing plate 15 is the same as the outer diameter of the exhaust pipe 4. The diameter of the limiting plate 13 is larger than the diameter of the guide rod 12.
[0026] By adopting the above technical solution, when the exhaust pipe 4 discharges dry gas, the gas pushing force will cause the sealing plate 15 to move upward and lift, thereby pulling the spring 14 to extend and the guide rod 12 to move upward. After the sealing plate 15 is lifted, the exhaust pipe 4 opens, ensuring that the gas can be discharged normally. When the sealing plate 15 rises, the limiting plate 13 at the bottom of the guide rod 12 will limit the maximum rising distance of the entire guide rod 12, thereby preventing the guide rod 12 from moving too high and disengaging from the limit of the cross frame 11; When the device is not in use, the sealing plate 15 slides steadily downward under its own weight using the guide rod 12 to seal the upper opening of the exhaust pipe 4. The spring 14 can pull the sealing plate 15 to close stably, preventing the sealing plate 15 from sliding randomly and opening.
[0027] Working Principle: When using this low-temperature evaporation gas-liquid separation device, the entire device is first connected to the steam discharge pipe of the evaporation equipment via the air inlet channel 2. Steam enters the separation tank 1 through the air inlet channel 2. The steam is divided at the inclined surface of the guide cone 9 and rises along the inner edge of the separation tank 1. With the help of the arc-shaped top cover 3, the steam converges towards the center and first collides and rubs against the exhaust pipe 4. Some of the liquid in the steam can adhere to the surface of the exhaust pipe 4. As the liquid continues to converge, it flows downward along the exhaust pipe 4. The remaining steam flows downward under the flow restriction of the exhaust pipe 4. As steam passes through the perforated mesh plate 5, it rubs and collides with the plate. The mesh strips of the perforated mesh plate 5 can adhere a large amount of liquid in the steam, causing the liquid to gather on the plate and drip downwards. Some steam is blocked by the perforated mesh plate 5 and flows outwards, creating a downward backflow. At this time, the downward backflowing steam is limited by the protruding part at the upper end of the guide cone 9, forming a swirling upward flow, thus completing a second round of collision and friction. Another part of the steam directly passes through the perforated mesh plate 5 and enters the sealing cylinder 6, where it collides and rubs against the inner wall of the sealing cylinder 6. The liquid in the steam adheres to the gas. At this point, the steam has undergone a multi-stage adhesion and gas-liquid separation process. The steam that finally enters the collection tank 7 continues to collide and rub against the inner wall of the collection tank 7, adhering to the remaining trace amount of liquid, thus completely removing the liquid from the gas. The dry gas then gathers at the bottom of the collection tank 7 and, through opposing collisions, rises and exits through the exhaust pipe 4. The liquid inside the collection tank 7 is discharged through the drainage channels on both sides and stored inside the guide cone 9. Simultaneously, when the dry gas is discharged through the exhaust pipe 4, the gas pushing force causes the sealing plate 15 to rise, thereby pulling the spring 14 to extend and... When the guide rod 12 moves upward and the sealing plate 15 is raised, the exhaust pipe 4 opens, ensuring that the gas can be discharged normally. When the device is not in use, the sealing plate 15 slides steadily downward under its own weight using the guide rod 12, and closes the upper opening of the exhaust pipe 4. The spring 14 can pull the sealing plate 15 to close stably, preventing the sealing plate 15 from sliding randomly and opening. This can stably and effectively seal the exhaust pipe 4 opening. At this time, the top cover 3 can be removed separately, and the liquid inside the guide cone 9 can be discharged by opening and closing the valve pipe 10. This is the working principle of the low-temperature evaporation gas-liquid separation device.
