Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of gas-liquid separation equipment, and in particular relates to a gas-liquid separation device. Background Art
[0002] The gas-liquid separation device is mainly used to efficiently separate the gas and liquid components in mixed media in industrial processes. Its core purpose is to achieve pure separation of the two phases through physical mechanisms such as gravity sedimentation, centrifugal force, inertial collision or filtration, thereby protecting downstream equipment from damage by gas-liquid mixed fluids, while recovering valuable resources and ensuring process safety and environmental protection standards. It is widely used in petrochemical, metallurgy, energy, environmental protection, pharmaceuticals, refrigeration and other fields.
[0003] At present, gas-liquid separation devices generally face contradictory defects in performance and cost in practical applications: on the one hand, although traditional simple separation devices have the advantages of simple structure and low initial investment, their separation efficiency is limited by the limitations of the physical mechanism itself. For example, the capture capacity of tiny droplets or low-density aerosols is insufficient, which makes it difficult to meet the needs of high-precision separation, and they are easily affected by working conditions such as flow fluctuations and pressure changes, resulting in poor separation stability. On the other hand, although high-performance separation equipment can significantly improve separation efficiency and accuracy, its internal structure is complex and requires reliance on precision components or special materials, resulting in a significant increase in equipment manufacturing costs, operation and maintenance energy consumption, and maintenance difficulties. For example, centrifugal separators require continuous power drive, and membrane separation systems have bottlenecks such as easy clogging and short life, which further push up the full life cycle cost. This technical dilemma of "high efficiency and low cost cannot be achieved at the same time" not only increases the difficulty of enterprise equipment selection decision-making, but also restricts the promotion and application of gas-liquid separation technology in emerging fields such as fine chemicals and clean energy, and has become a technical pain point that the industry urgently needs to break through.

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0026] In order to solve the problems of the existing gas-liquid separation device, such as the inability to achieve both high efficiency and low cost, the high manufacturing cost and operation and maintenance difficulty caused by the complex structure, the poor adaptability and the rising cost of the whole life cycle caused by the lack of intelligent control ability and the lack of modular design, the present invention provides a gas-liquid separation device. In order to further illustrate the structure of the present invention, the detailed description is as follows in conjunction with the drawings:
[0027] See also Figure 1 , a gas-liquid separation device comprises a cylinder 1, a float 2, a drain valve plate 3 and a partition plate 4. In this embodiment, the cylinder is composed of a cylinder body and a cylinder cover sealed and mounted on the cylinder body, and the interior of the cylinder forms an inner cavity, which is a chamber for gas-liquid separation.
[0028] The cylinder is provided with a gas-liquid inlet 1-1, a liquid outlet 1-2 and a gas outlet 1-3 connected to the inner cavity of the cylinder. That is, the gas-liquid inlet is used to input the gas-liquid mixture into the inner cavity, and the liquid outlet and the gas outlet are used to discharge the separated liquid and gas respectively. In this embodiment, the gas-liquid inlet and the liquid outlet are respectively arranged on both sides of the cylinder, and the gas outlet is arranged on the upper part of the cylinder. The exhaust pipe body 5 connected to the gas outlet is connected to the liquid inlet pipe body 6 connected to the gas-liquid inlet. Specifically, the gas-liquid inlet, the liquid outlet and the gas outlet are formed on the cylinder body. The gas outlet and the liquid inlet pipe body are right-angle elbows, and the horizontal sections of the gas outlet and the liquid inlet pipe body are connected to the cylinder body, and the vertical section is a common pipe body. This vertical section is a design of a common pipe body, so that the gas-liquid mixture flows in and the gas discharge after separation shares the vertical section of the same pipeline. This structure simplifies the pipeline layout and reduces the setting of independent gas exhaust pipes, thereby reducing the structural complexity and manufacturing cost of the system. It also helps to reduce the overall size of the equipment, making it more compact and suitable for application environments with limited space.
[0029] The partition plate is arranged between the gas-liquid inlet and the float and the drain valve plate, and the partition plate forms a barrier member for the gas-liquid mixture entering the gas-liquid inlet. In this embodiment, the partition plate divides the inner cavity of the cylinder into an overflow trough and a drain trough located on both sides, the gas-liquid inlet is connected to the overflow trough, the liquid outlet is connected to the drain trough, and the float and the drain valve plate are arranged in the drain trough. Two sewage outlets 1-4 are arranged at the lower part of the cylinder, and the two sewage outlets are connected to the overflow trough and the drain trough respectively. The gas-liquid mixture enters the overflow trough from the gas-liquid inlet, and the liquid level of the overflow trough rises and overflows from the top into the drain trough.
[0030] The discharge valve plate forms a sealing component for blocking the liquid outlet. The float is connected to the discharge valve plate, and the float drives the discharge valve plate to open and block the liquid outlet through floating and sinking actions. That is, as the liquid level in the drainage tank rises to a preset position, the float is pulled up by the buoyancy to open the discharge valve plate, and the liquid is discharged from the liquid outlet. After the liquid is discharged, the liquid level drops and causes the float to sink, and the discharge valve plate moves downward and blocks the liquid outlet again, thereby stopping the discharge. In the present embodiment, specifically, the liquid outlet is connected to the inner cylinder end 7 extending horizontally to the inner cavity of the cylinder, and the cross-section of the inner cylinder end is rectangular, which can be welded to the inner wall of the cylinder body. The end of the inner cylinder end is closed and provided with a vertically through valve port, the valve port is circular, the valve port is opened on the upper and lower cylinder walls of the inner cylinder end and the vertical projections overlap, and the valve ports are respectively equipped with discharge valve plates that realize sealing from top to bottom. An annular sealing seat 8 is installed on the upper part of the valve mouth of the inner cylinder end, and the annular sealing seat forms a wedge-shaped sealing ring surface that is wide at the top and narrow at the bottom. The outer edge of the drain valve plate forms a wedge-shaped sealing ring surface that is wide at the top and narrow at the bottom and is adapted to the wedge-shaped sealing ring surface. The annular sealing seat is fixed to the upper part of the upper cylinder wall and the upper part of the lower cylinder wall of the inner cylinder end by screws or welding. The drain valve plate is a circular valve plate, and an annular sealing groove is processed on the wedge-shaped sealing ring surface, and a sealing ring is installed in the sealing groove. The center position of the drain valve plate is connected to a vertical connecting rod 9, and the drain valve plate is connected to the float located above the inner cylinder end through the vertical connecting rod. The pressure (gas-liquid mixed medium) borne by the upper and lower drain valve plates described in the present invention is equal in magnitude and opposite in direction. Therefore, the upper and lower drain valve plates will not be affected by the pressure of the gas-liquid mixed medium, and the action of the drain valve plate is sensitive and reliable. In this embodiment, the float uses a cylindrical float.
[0031] The balancing weight 10 is installed on the floating body, and the balancing weight applies pressure to the drain valve plate to ensure the sealing force between the drain valve plate and the valve port (sealing seat) after the liquid level drops. The balancing weight is a mass block fixed to the lower part of the floating body by fasteners.
[0032] See also Figure 2, the drain valve plate is equipped with a vertical guide component, and the inner tube end is provided with a vertical guide structure adapted to the vertical guide component. The function of the vertical guide component is to ensure that the movement of the float and the drain valve plate is sensitive and stable, and to prevent the mechanism from being stuck or the seal from failing due to the deflection. In this embodiment, specifically, the vertical guide component is four guide rods 11 connected to the drain valve plate and extending vertically downward, and the vertical guide structure is formed by the inner hole edge of the annular sealing seat, and the inner hole edge of the annular sealing seat forms a radial limit structure for the combined structure of all guide rods. That is, the four guide rods form a circumferential enclosure combined structure, similar to the guide rod, the inner hole edge of the annular sealing seat is similar to the guide hole, and the four guide rods and the inner hole edge of the annular sealing seat form a vertical guide structure. This guide structure does not need to be equipped with an additional guide hole, and the valve port itself plays the role of the guide hole. Not only is the structure simple and the failure rate is low, but more importantly, it prevents the hidden danger of sealing failure caused by setting an independent guide hole at the inner tube end. This design greatly improves the service life of the device and reduces the failure rate. In order to improve the wear resistance of the guide rod, the guide rod is composed of a screw connected to the discharge valve plate and a rod sleeve mounted on the screw. The rod sleeve is made of wear-resistant material or is subjected to wear-resistant treatment.
[0033] In order to further improve the gas-liquid separation performance of this device, please refer to Figure 3 The separation device described in this embodiment is further modified by installing a step baffle 12 and an overflow orifice plate 13 in the overflow trough.
[0034] The step baffle is arranged on two opposite inner walls of the overflow trough, one of which is the entrance side of the gas-liquid mixture. The step baffle forms a staggered partition structure between the two inner walls, and the baffle forms a downward slope. The step baffle is located below the gas-liquid inlet as a whole. After the gas-liquid mixture enters the overflow trough, it turns back and flows downward on the step baffle. The step baffle structure forms staggered partitions in the overflow trough, so that the gas-liquid mixture turns back and flows downward along the baffle slope after entering the overflow trough, effectively prolonging the residence time of bubbles in the liquid phase and increasing their chances of floating and separation. At the same time, the staggered arrangement of the baffles changes the liquid flow path, reduces the overall flow rate, and allows smaller bubbles to have sufficient time to gather and merge into larger bubbles, thereby improving the separation efficiency. In addition, the downward-sloping baffle slope can guide the bubbles to gather upward, while the liquid phase continues to flow along the baffle, forming a clear gas-liquid separation interface. This structural design utilizes the principles of fluid dynamics to achieve a more efficient gas-liquid separation effect by controlling the flow rate, increasing the bubble residence time and optimizing the bubble aggregation process.
[0035] The overflow orifice plate is a horizontal perforated baffle plate located above the gas-liquid inlet in the overflow tank. The rising liquid will pass through the overflow orifice plate. The holes on the orifice plate allow the liquid to pass through in the form of a local jet, forming a pressure difference and micro-eddies, which help the bubbles to gather, merge and float up and escape at the orifice, while reducing the possibility of bubbles entering the subsequent flow channel with the liquid, further improving the gas-liquid separation efficiency.
[0036] Furthermore, a hole is opened at a position corresponding to the overflow groove in the barrel cover, and a hole plugging cover 14 is sealed and installed at the hole by means of fasteners. An ultrasonic vibrating rod 15 extending toward the lower part of the overflow groove is integrated on the hole plugging cover. A middle hole is opened at the center of the overflow orifice plate to make way for the ultrasonic vibrating rod. The ultrasonic vibrating rod is an existing known component, which works as an accessory and can further accelerate the aggregation or rupture of bubbles, thereby improving the gas-liquid separation efficiency.
