Technical Field

[0001] This utility model relates to the technical field of vehicle air supply systems, specifically to a gas-liquid separator and a central air supply system. Background Technology

[0002] As a key component of the central gas supply system, the gas-liquid separator's core function is to separate the liquid medium from the mixed gas, ensuring the dryness of the output gas and the stability of system operation.

[0003] In existing technologies, conventional gas-liquid separators mostly employ baffle collision or simple gravity settling methods for separation. Baffle separators rely on the inertial difference between gas and liquid for collision separation, but the liquid medium easily adheres to the baffle plates, forming an oil film or liquid film that hinders subsequent separation. Gravity settling has a weak ability to capture tiny droplets, resulting in a high droplet residue rate in the mixed gas and insignificant gas-liquid separation effect. Furthermore, existing gas-liquid separators have complex structures, and liquid discharge control often suffers from problems such as liquid residue or untimely discharge, affecting the stable operation of the system.

[0004] Therefore, it is necessary to provide new gas-liquid separators and a central gas supply system. Utility Model Content

[0005] In view of this, the present invention provides a gas-liquid separator and a central gas supply system that uses a turbine separator to throw liquid droplets toward the inner wall of the separation chamber by centrifugal force, thereby achieving efficient gas-liquid separation.

Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0025] like Figure 1 , Figure 2 As shown, this embodiment provides a gas-liquid separator 100 including an air inlet assembly 1, a separation assembly 2 disposed on one side of the air inlet assembly 1, a liquid collection assembly 3 communicating with the separation assembly 2, and a liquid outlet assembly 4. The air inlet assembly 1 is used to input a mixed gas containing liquid from a central gas supply system; the separation assembly 2 is used to separate the mixed gas containing liquid into gas and liquid; the liquid collection assembly 3 is used to collect the liquid output from the separation assembly 2; and the liquid outlet assembly 4 is used to discharge the liquid collected by the liquid collection assembly 3 from the gas-liquid separator 100.

[0026] In some embodiments, the air intake assembly 1 includes an air inlet 11 disposed at the top, an air intake chamber 12 communicating with the air inlet 11, and a partition plate 13 located at the bottom of the air intake chamber 12. The air inlet 11 is located at the top of the gas-liquid separator 100, with one end connected to a pipe of an external central air supply system and the other end directly communicating with the air intake chamber 12. The air inlet 11 is used to receive a liquid-containing mixed gas supplied from the central air supply system. The intake chamber 12 is a cavity structure with a certain volume. It accommodates the liquid-containing mixed gas input from the intake port 11, serving as an initial deceleration and buffer for the high-speed mixed gas supplied from the external central air source system. This reduces the direct impact of the mixed gas on the separation component 2, achieving buffering and flow stabilization. Consequently, the mixed gas enters the separation component 2 more smoothly and uniformly, creating favorable conditions for efficient separation and improving the final gas-liquid separation effect. Simultaneously, buffering reduces the impact of high-speed airflow and droplets on the separation component 2, extending the equipment's service life. A partition plate 13 is located at the bottom of the intake chamber 13 and separates the intake component 1 from the separation component 2. The partition plate 13 has multiple through-holes 131, evenly distributed in a circular pattern, and these holes communicate with the separation component 3. Multiple air inlets 131 are used to guide and transport the mixed gas after it has been buffered and stabilized by the air inlet chamber 12 to the separation component 2. Through multiple circumferentially evenly distributed air inlets 131, the originally concentrated airflow is dispersed into multiple fine and uniform airflows, so that the gas can enter the separation component 2 evenly and avoid the airflow from deviating to one side.

[0027] In some of these embodiments, such as Figure 3 As shown, the separation assembly 2 is located on one side of the intake assembly 1. The separation assembly 2 includes a separation chamber 21, a turbine separator 22 located at the top of the separation chamber 21, and an outlet 23. The separation chamber 21 is located below the intake assembly 1 and above the liquid collection assembly 3. The upper end of the separation chamber 21 is connected to the partition plate 12, and the lower end of the separation chamber 21 is directly connected to the liquid collection assembly 3. The turbine separator 22 is located at the top of the separation chamber 21. The top of the separation chamber 21 is connected to the intake chamber 12 through the partition plate 13 and the air inlet 131 on the partition plate 13. The separation chamber 21 provides a physical space for the centrifugal separation of the mixed gas, allowing the liquid in the gas to separate and flow along the cavity wall of the separation chamber 21 under the action of centrifugal force and gravity. The separation chamber 21 includes a confluence section 211 and an inlet section 212 located at the bottom. The confluence section 211 is inclined downward and tapered, used to guide the separated liquid through the inner wall of the confluence section 211 to the bottom of the separation chamber 21. The inlet section 212 is located in the lower region of the separation chamber 21. The inlet section 212 is expanded to optimize the liquid flow path, prevent liquid residue in the separation chamber 21, ensure efficient liquid collection, and improve the liquid discharge efficiency of the gas-liquid separator 100. The turbine separator 22 includes a turbine fan with a centrifugal structure, capable of high-speed rotation under airflow. The turbine separator 22 is fixed to the partition plate 13, and its position aligns with the positions of multiple air inlets 131. This allows the mixed gas entering through the air inlets 131 to drive the turbine fan of the turbine separator 22 to rotate, using centrifugal force to throw the liquid in the mixed gas towards the inner wall of the separation chamber 21, achieving efficient gas-liquid separation. Compared to simple gravity separation, centrifugal separation using the turbine separator 22 is more efficient. Furthermore, the turbine fan disperses the airflow, making it easier for droplets to be ejected, thus improving the separation effect. The rotating structure also has a flow-stabilizing effect, making the separation process more stable and continuous. Finally, under gravity, the liquid flows along the inner wall of the separation chamber 21 to the lower liquid collection assembly 3. The air outlet 23 is located on the inner wall of the separation chamber 23, and is positioned away from the confluence section 211. One end of the air outlet 23 is directly connected to the separation chamber 21, and the other end is connected to the gas output end of the central gas supply system. The air outlet 23 is used to output dry gas for use by the central gas supply system.

[0028] In some embodiments, the liquid collection assembly 3 includes a liquid collection chamber 31 and a valve 32 disposed at the bottom of the liquid collection chamber 31. The liquid collection chamber 31 is a hollow cavity structure, directly connected to the separation chamber 21. The liquid collection chamber 31 has a tapered structure and is used to collect liquid flowing from the separation chamber 21, serving as a temporary storage buffer and providing volume support for the subsequent drainage process. The valve 32 is disposed at the bottom of the liquid collection chamber 31 and connects the liquid collection chamber 31 to the drainage chamber 41 of the drainage assembly 4. The valve 32 can perform opening / closing actions, controlling the timing of liquid drainage from the liquid collection chamber 31. When open, it allows liquid to flow into the drainage chamber 41; when closed, it blocks the liquid flow, achieving controllable drainage.

[0029] In some embodiments, the liquid discharge assembly 4 includes a liquid discharge chamber 41, a liquid discharge port 42 communicating with the liquid discharge chamber 41, and a controller 43. The upper end of the liquid discharge chamber 41 is connected to a valve 32, and the lower end is connected to the liquid discharge port 42. The liquid discharge chamber 41 receives liquid flowing into the liquid collection chamber 31 through the valve 32, providing a buffer and channel for the liquid to be discharged to the liquid discharge port 42. The liquid discharge port 4 is connected to the liquid discharge chamber 41 and is located in the bottom region of the gas-liquid separator 100. The liquid discharge port 4 is used to discharge the liquid in the liquid discharge chamber 41 from the gas-liquid separator 100, completing the final discharge of the liquid. The controller 43 is connected to the valve 32 via an electrical signal. The controller 43 controls the opening and closing of the valve 32. The controller 43 receives liquid level signals or other control signals and automatically controls the opening and closing of the valve 32 to automate the discharge process, ensuring timely and accurate discharge, preventing liquid overflow or insufficient collection, and optimizing the overall efficiency of the gas-liquid separator.

[0030] The working process of the gas-liquid separator 100 of this utility model is as follows: the liquid-containing mixed gas from the external central gas supply system is input through the inlet 11 and enters the inlet chamber 12, where it undergoes initial deceleration and buffering, and the airflow speed decreases from an initial high speed to a stable state. The buffered gas is then dispersed into uniform fine streams through multiple inlet holes 131 arranged around the circumference of the partition plate 13, and enters the separation chamber 21 vertically. Subsequently, the multiple fine streams impact the centrifugal fan of the turbine separator 22, driving it to rotate at high speed and generate centrifugal force. Under centrifugal force, the liquid droplets in the mixed gas are thrown towards the inner wall of the separation chamber 21, realizing the gas-liquid separation. Initial separation: Dry gas flows upward along the inner wall of separation chamber 21 and is finally discharged through outlet 23 to the gas output end of the central gas supply system; then, the droplets attached to the inner wall of separation chamber 21 slide down the inclined surface of confluence section 211 under the action of gravity, and flow into the liquid collection chamber 31 below after being gathered by inlet section 212. The liquid collection chamber 31 temporarily stores and buffers the liquid; the controller 43 monitors the liquid level of the liquid collection chamber 31 in real time. When the liquid level reaches the preset threshold, it issues an opening command to control valve 32 to open, and the liquid flows from the liquid collection chamber 31 into the liquid outlet chamber 41 and is finally discharged through outlet 42; after the liquid level drops to the lower limit threshold, the controller 43 commands valve 32 to close, completing a single liquid discharge cycle.

[0031] The gas-liquid separator 100 of this utility model includes an air inlet assembly 1, a separation assembly 1 disposed on one side of the air inlet assembly 1, a liquid collection assembly 3 communicating with the separation assembly 1, and a liquid outlet assembly 4. The air inlet assembly 1 includes an air inlet 11 disposed at the top, an air inlet chamber 12 communicating with the air inlet, and a partition plate 13 located at the bottom of the air inlet chamber. The separation assembly 2 includes a separation chamber 21 and a turbine separator 22 fixed at the lower end of the partition plate 131. The liquid collection assembly 3 includes a liquid collection chamber 31 and a valve 32 disposed at the bottom of the liquid collection chamber 31. The liquid outlet assembly 4 includes a liquid outlet chamber 41, a liquid outlet 42 communicating with the liquid outlet chamber 41, and a controller 43. The gas-liquid separator 100 of this invention utilizes a turbine separator 22 that rotates at high speed under the action of airflow, using centrifugal force to throw liquid droplets against the inner wall of the separation chamber, achieving efficient gas-liquid separation, which is significantly more efficient than the traditional gravity separation method. The air inlet chamber 12 cooperates with the circumferentially distributed air inlet holes 131 to buffer and divert the high-speed entering mixed gas, so that the gas enters the separation component evenly, reducing impact, improving the separation effect and extending the equipment life. The liquid collection chamber 31 is connected to the liquid outlet component 4 through a valve 32. The controller 43 automatically controls the opening and closing of the valve according to the liquid level signal, realizing the timed and quantitative discharge of liquid, avoiding liquid retention or overflow, and improving the automation level of the system. The separation chamber 21 includes a confluence part 211 and an inlet part 212, which effectively guides the liquid flow to the liquid collection chamber, prevents liquid residue, and ensures smooth and efficient separation and drainage processes. The gas-liquid separator 100 of this invention has a simple structure, is easy to install, and has good versatility and practicality.
