Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of gas-liquid separation equipment, and particularly relates to a baffled gas-liquid separation device. Background Technology
[0002] The baffled gas-liquid separator is mainly used in industrial processes to efficiently separate gas and liquid components in a mixed medium. Its core purpose is to achieve pure separation of the two phases through physical mechanisms such as gravity sedimentation, centrifugal force, inertial impaction, or filtration, thereby protecting downstream equipment from damage caused by the gas-liquid mixture, recovering valuable resources, and ensuring process safety and environmental compliance. It is widely used in petrochemical, metallurgical, energy, environmental protection, pharmaceutical, and refrigeration fields.
[0003] Currently, baffled gas-liquid separators generally face a contradictory performance-cost trade-off in practical applications. On the one hand, while traditional simple separation devices have the advantages of simple structure and low initial investment, their separation efficiency is limited by the inherent limitations of the physical mechanism itself. For example, they lack the ability to capture tiny droplets or low-density aerosols, making it difficult to meet the requirements of high-precision separation. Furthermore, they are easily affected by operating conditions such as flow fluctuations and pressure changes, resulting in poor separation stability. On the other hand, while high-performance separation equipment can significantly improve separation efficiency and precision, its complex internal structure requires precision components or special materials, leading to a substantial increase in equipment manufacturing costs, operation and maintenance energy consumption, and maintenance difficulty. For example, centrifuges require continuous power drive, and membrane separation systems suffer from bottlenecks such as easy clogging and short lifespan, further increasing the total life cycle cost. This technical dilemma of "incompatibility between high efficiency and low cost" not only increases the difficulty of equipment selection decisions for enterprises but also restricts the promotion and application of gas-liquid separation technology in emerging fields such as fine chemicals and clean energy, becoming a technical pain point that the industry urgently needs to overcome.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0024] To address the problems of current barrier-type gas-liquid separators, such as the trade-off between high efficiency and low cost, complex structure leading to high manufacturing and maintenance costs, insufficient intelligent control capabilities, and poor adaptability and escalating life-cycle costs due to a lack of modular design, this utility model provides a barrier-type gas-liquid separator. To further illustrate the structure of this utility model, a detailed description is provided below in conjunction with the accompanying drawings:
[0025] Please see Figure 1 A baffled gas-liquid separator includes a cylinder 1, a float 2, a drain valve plate 3, and a partition plate 4. In this embodiment, the cylinder consists of a cylinder and a cylinder cover sealed and installed on the cylinder body. The interior of the cylinder forms an inner cavity, which is the chamber for gas-liquid separation.
[0026] The cylinder body is equipped with a gas-liquid inlet 1-1, a liquid outlet 1-2, and a gas outlet 1-3, all communicating with the inner cavity of the cylinder. Specifically, the gas-liquid inlet is used to input the gas-liquid mixture into the inner cavity, while the liquid and gas outlets are used to discharge the separated liquid and gas, respectively. In this embodiment, the gas-liquid inlet and liquid outlet are located on both sides of the cylinder body, and the gas outlet is located at the top of the cylinder body. An exhaust pipe 5, connecting to the gas outlet, is connected to an inlet pipe 6, connecting to the gas-liquid inlet. Specifically, the gas-liquid inlet, liquid outlet, and gas outlet are formed within the cylinder body. The gas outlet and inlet pipe are right-angle bends; the horizontal sections of the gas outlet and inlet pipe connect to the cylinder body, while the vertical sections are shared pipes. This design, with a shared vertical pipe, allows the gas-liquid mixture to flow in and the separated gas to exit through the same vertical pipe section. This structure simplifies the pipe layout, reduces the need for independent gas discharge pipes, and thus reduces 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 space-constrained applications.
[0027] A partition plate is disposed between the gas-liquid inlet and the float and drain valve plate, forming a barrier against 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, and the liquid outlet is connected to the drain trough. The float and drain valve plate are disposed in the drain trough. The lower part of the cylinder is provided with two drain ports 1-4, which are respectively connected to the overflow trough and the drain trough. The gas-liquid mixture enters the overflow trough from the gas-liquid inlet, the liquid level in the overflow trough rises, and overflows from the top into the drain trough.
[0028] The drain valve plate forms a sealing component to block the liquid outlet. A float is connected to the drain valve plate, and the float's buoyancy drives the drain valve plate to open and block the liquid outlet. Specifically, as the liquid level in the drain tank rises to a preset position, the float rises under buoyancy, pulling the drain valve plate open, and liquid is discharged from the liquid outlet. After the liquid is discharged, the liquid level drops, causing the float to sink, and the drain valve plate moves downwards to block the liquid outlet again, thus stopping the discharge. In this embodiment, specifically, the liquid outlet connects to the inner cylinder end 7, which extends horizontally into the inner cavity of the cylinder. The cross-section of the inner cylinder end is rectangular and can be welded to the inner wall of the cylinder. The end of the inner cylinder end is closed and has a vertically penetrating valve port. The valve port is circular and is located on the upper and lower cylinder walls of the inner cylinder end, with their vertical projections coinciding. Each valve port is fitted with a drain valve plate that achieves a top-down sealing effect. An annular sealing seat 8 is installed on the upper part of the valve port at the inner cylinder end. The annular sealing seat forms a wedge-shaped sealing ring surface that is wider at the top and narrower at the bottom. The outer edge of the drain valve plate forms a wedge-shaped sealing ring surface that is wider at the top and narrower at the bottom, which 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 at the inner cylinder end by screws or welding. The drain valve plate is a circular valve plate, and an annular sealing groove is machined on the wedge-shaped sealing ring surface. A sealing ring is installed in the sealing groove. A vertical connecting rod 9 is connected to the center of the drain valve plate, and the drain valve plate is connected to a float located above the inner cylinder end through the vertical connecting rod. In this utility model, the pressure (gas-liquid mixture) borne by the upper and lower drain valve plates is equal in magnitude and opposite in direction. Therefore, the upper and lower drain valve plates are not affected by the pressure of the gas-liquid mixture, and the operation of the drain valve plates is sensitive and reliable. In this embodiment, a cylindrical float is selected.
[0029] A counterweight 10 is installed on the float. The counterweight 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 counterweight is a mass block fixed to the lower part of the float by fasteners.
[0030] Please see Figure 2The drain valve plate is equipped with vertical guide components, and the inner cylinder end has a vertical guide structure adapted to the vertical guide components. The function of the vertical guide components is to ensure the sensitive and stable movement of the float and the drain valve plate, and to prevent the mechanism from jamming or the seal from failing due to swaying. In this embodiment, specifically, the vertical guide components are four guide rods 11 connected to the drain valve plate and extending vertically downward. 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 limiting structure for all guide rod combinations. That is, the four guide rods form a circumferential enclosure combination structure, similar to guide rods, and the inner hole edge of the annular sealing seat is similar to a guide hole. The four guide rods and the inner hole edge of the annular sealing seat form a vertical guide structure. This guide structure does not require the addition of an additional guide hole; the valve port itself functions as a guide hole. This not only simplifies the structure and reduces the failure rate, but more importantly, it prevents the potential seal failure that exists with an independent guide hole at the inner cylinder end. This design significantly improves the service life of the device and reduces the failure rate. To improve the wear resistance of the guide rod, the guide rod consists of a screw rod connected to the drain valve plate and a sleeve for mounting the screw rod. The sleeve is made of wear-resistant material or is treated with wear resistance.
[0031] To further improve the gas-liquid separation performance of this device, please refer to [link / reference]. Figure 3 Further modifications were made to the separation device described in this embodiment. Specifically, a stepped baffle 12 and an overflow orifice plate 13 were added to the overflow trough.
[0032] A stepped baffle is installed on two opposing inner walls of the overflow tank, one of which is the inlet side of the gas-liquid mixture. The stepped baffle forms an alternating baffle structure between the two inner walls, with the baffles creating a downward slope. The entire stepped baffle is located below the gas-liquid inlet. After entering the overflow tank, the gas-liquid mixture flows downwards and is deflected by the stepped baffles. This stepped baffle structure, by creating alternating baffles within the overflow tank, causes the gas-liquid mixture to flow downwards along the baffle slope after entering the overflow tank, effectively extending the residence time of bubbles in the liquid phase and increasing their chance of rising and separating. Simultaneously, the alternating arrangement of the baffles changes the liquid flow path, reducing the overall flow velocity and allowing smaller bubbles sufficient time to aggregate and merge into larger bubbles, thereby improving separation efficiency. Furthermore, the downward-sloping baffle surface guides bubbles to aggregate upwards, while the liquid phase continues to flow along the baffle, forming a clear gas-liquid separation interface. This structural design utilizes fluid dynamics principles to achieve more efficient gas-liquid separation by controlling flow rate, increasing bubble residence time, and optimizing the bubble aggregation process.
[0033] The overflow orifice plate is a horizontal perforated baffle located above the gas-liquid inlet in the overflow channel. As the liquid level rises, it passes through the orifice plate. The perforations allow the liquid to pass through in a localized jet stream, creating a pressure difference and micro-vortices. This helps bubbles to gather, merge, and escape at the orifice, while reducing the likelihood of bubbles entering subsequent flow channels with the liquid. This further improves gas-liquid separation efficiency.
[0034] Furthermore, an opening is made at the position of the overflow channel corresponding to the bucket lid. A hole plug 14 is installed at the opening using fasteners. An ultrasonic vibrating rod 15 extending to the lower part of the overflow channel is integrated on the hole plug. A central hole is made 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. It works as an accessory and can further accelerate the aggregation or rupture of bubbles, thereby improving the gas-liquid separation efficiency.
[0035] Example 2
[0036] Please see Figure 4 The gas-liquid inlet is located at the top of the cylinder, the liquid outlet is located on the side of the cylinder, and the float and the drain valve plate are located below the gas-liquid inlet. The partition plate is located between the float and the gas-liquid inlet, and the partition plate forms an inclined guide plate that sinks to the side of the float at one end.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
