Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separation technology, and in particular, it is a simple self-controlled liquid level gas-liquid separator. Background Technology

[0002] In a gas-liquid separator, due to the density difference between gas and liquid, when the gas and liquid flow together, the liquid, under the influence of gravity or when encountering an obstacle, will continue to move forward due to inertia, while the gas will be deflected. Typically, the liquid will sink, and the gas will rise and be expelled, thus achieving the separation effect.

[0003] Existing liquid ring pump gas-liquid separators are typically manufactured using metal materials with wall thicknesses ranging from 3mm to 20mm. The tank shape is mostly formed by rolling steel plates into a cylindrical shape and then welding them. Additional openings are required on the outer wall of the tank for welding flange fittings, and external level gauges and level sensors are installed to determine the liquid level. Furthermore, electrically controlled valves are needed to control the opening and closing of valves based on the liquid level signal, thereby controlling the replenishment and discharge of liquid and the liquid level. The problems are: complex structure, high manufacturing difficulty, heavy weight, high production cost, and high operating and maintenance costs. When used in simple liquid ring pump units such as vacuum priming devices, since the operation does not involve any hazardous gases or liquids and the exhaust pressure is zero, it is unnecessary to use such a high-strength, heavy gas-liquid separator. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes a simple self-controlled liquid level gas-water separator, which has a simple structure, light weight, is easy to install, and has low manufacturing and production costs.

[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:

[0006] A simple self-controlled liquid level gas-liquid separator includes a tank. An air outlet is provided on the upper end face of the tank. A water inlet and a vacuum pump water supply inlet are provided on the front of the tank. The water inlet is located in the middle of the front, and the vacuum pump water supply inlet is located in the lower part of the front. An air inlet is provided on the upper side of the tank, and an overflow outlet is provided in the middle of the back of the tank. Standard upper and lower clamp-sealed connectors are provided at the air outlet, air inlet, and overflow outlet. A float-type automatic water replenishment switch is provided at the water inlet and is located inside the tank.

[0007] Furthermore, the tank body is a cuboid or a cylinder.

[0008] Furthermore, the tank body is formed in one piece.

[0009] Specifically, the can is made of transparent plastic.

[0010] Specifically, the thickness of the tank body is 0.5mm-3mm.

[0011] Specifically, the float-type automatic water replenishment switch is connected to the first water supply pipeline, and the vacuum pump water supply port is connected to the second water supply pipeline.

[0012] This utility model has a simple structure, is lightweight, easy to install, and has low manufacturing and production costs. The tank is equipped with a float-type automatic water replenishment switch and an overflow port, which realizes automatic control of the liquid level in the tank. The tank body is made of plastic material and has a certain degree of transparency, making it easy to see the internal liquid level. It is particularly suitable for liquid ring pump units in simple working conditions such as vacuum water priming devices. Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 for Figure 1 Top view, Figure 3 for Figure 1 The right view, Figure 4 for Figure 1 AA cross-section diagram, such as Figures 1 to 4 As shown, a simple self-controlled liquid level gas-liquid separator includes a tank 1. An air outlet 2 is provided on the upper end face of the tank 1. A water inlet 3 and a vacuum pump water supply inlet 4 are provided on the front of the tank 1. The water inlet 3 is located in the middle of the front, and the vacuum pump water supply inlet 4 is located in the lower part of the front. An air inlet 5 is provided on the upper side of the tank 1, and an overflow outlet 6 is provided in the middle of the back of the tank 1. Standard upper and lower clamp-sealed connectors are provided on the air outlet 2, air inlet 5, and overflow outlet 6. A float-type automatic water replenishment switch 7 is provided on the water inlet 3 and is located inside the tank 1.

[0019] The tank body 1 is a cuboid or a cylinder. In this embodiment, the tank body 1 is a cylinder. The tank body 1 is integrally formed and is made of transparent plastic. In this embodiment, a first clamp-on standard upper and lower connector 8 is provided at the air outlet 2, a second clamp-on standard upper and lower connector 9 is provided at the air inlet 5, and a third clamp-on standard upper and lower connector 10 is provided at the overflow port 6. The air inlet 5 is connected to the liquid ring vacuum pump pipeline. The working water carried by the gas drawn by the liquid ring vacuum pump is discharged into the gas-water separator from the air inlet 5. The overflow port 6 discharges excess water from the gas-water separator.

[0020] The float-type automatic water replenishment switch 7 is connected to the first water supply pipeline, which is connected to a separate external water supply pipe. The vacuum pump water supply port 4 is connected to the second water supply pipeline, which is connected to the water supply hole at the bottom of the separator. The float-type automatic water replenishment switch 7 is an existing product that can be purchased from the market and used immediately. When the switch is turned on, the water in the pipe will replenish the air-water separator. Figure 5 A schematic diagram of a float-type automatic water replenishment switch, as shown below. Figure 5 As shown, when the float 7.1 rises, the trigger switch will stop water replenishment; conversely, when the float 7.1 falls, the switch will reopen to replenish water.

[0021] The thickness of tank 1 ranges from 0.5mm to 3mm, and in this embodiment, it is 1.8mm. The plastic material also possesses a degree of transparency, allowing easy observation of the liquid level inside tank 1, thus eliminating the need for an external level gauge. All external interfaces on the tank wall utilize standard upper and lower clamp-sealed connectors made of plastic material, requiring no welding and simplifying production. A float-type automatic water replenishment switch 7 and an overflow outlet are installed inside tank 1, enabling automatic control of the liquid level within the separator. This eliminates the need for electrically controlled valves and level sensors, effectively reducing potential points of failure and lowering production and maintenance costs.

[0022] During operation, water is first supplied to tank 1 via an automatic water replenishment device. Once the water level reaches a certain height, the automatic water replenishment device stops replenishing water. After the water level in the pump reaches the specified level, the liquid ring vacuum pump is activated. The working water carried by the gas drawn in by the liquid ring vacuum pump is discharged into tank 1. The gas separates under the action of gravity and inertia and is discharged from the gas outlet 2. Most of the water remains in tank 1 and flows back to the liquid ring vacuum pump for recycling through the vacuum pump water supply port 4. A small portion of the water is carried away as vapor with the gas. If the liquid level in tank 1 drops, the float-type automatic water replenishment switch 7 will automatically open to replenish fresh water. When the liquid level in tank 1 rises, the excess working fluid will be discharged from the pump through the overflow port 6. Since the vacuum water priming device generally does not operate continuously for long periods, the working fluid does not need to be cooled and can be recycled, achieving water conservation.

[0023] In summary, this utility model has a simple structure, is lightweight, easy to install, and has low manufacturing and production costs. The tank is equipped with a float-type automatic water replenishment switch and an overflow port, which realizes automatic control of the liquid level inside the tank. The tank body is made of plastic material and has a certain degree of transparency, making it easy to see the internal liquid level. It is particularly suitable for liquid ring pump units in simple working conditions such as vacuum water priming devices.
