For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0023] refer to Figure 1-Figure 3 , this embodiment provides a gas-liquid separator with a liquid level alarm device, including: a gas-liquid separation tank 12, a liquid level sensor 6, and an observation hole 2;

[0024] The inner wall of the gas-liquid separation tank 12 is provided with a partition 10 to divide the gas-liquid separation tank 12 into an upper tank and a lower tank; three liquid level sensors 6 are arranged inside the gas-liquid separation tank 12 along the height direction; one of the liquid level sensors is above the partition 10, and the others are below the partition; the signal output end of the liquid level sensor 6 is connected to the signal input end of the controller, and the signal output end of the controller is connected to the alarm device; the gas-liquid separation tank 12 is provided with the observation hole 2 on the side wall corresponding to the upper tank, for observing the water level of the upper tank;

[0025] The upper tank and the lower tank are connected through the first pipeline 1 and the third pipeline 5 respectively; the lower tank is connected to the outside through the second pipeline 3; T-type valves are respectively arranged on the first pipeline 1, the second pipeline 3 and the third pipeline 5.

[0026] The upper tank and the lower tank are respectively provided with maintenance holes and cover plates 7 for blocking the maintenance holes. When the gas-liquid separator works normally, the holes are blocked with the cover plates 7. When maintenance is performed, the cover plates 7 can be opened to perform cleaning and maintenance operations through the maintenance holes.

[0027] The top of the gas-liquid separation tank 12 is provided with an air inlet pipe and an exhaust pipe connected to the upper tank; the end of the air inlet pipe is lower than the end of the exhaust pipe. The gas-liquid separation tank 12 is provided with a pressure gauge 11 at the position corresponding to the upper tank. The gas-liquid mixture enters from the air inlet pipe 9, the gas is discharged from the exhaust pipe 8, and the liquid is separated downward by gravity and attached to the partition 10 and the gas-liquid separation tank 12. The partition 10 shortens the time for liquid separation. Open the T-valve on the third pipeline 5, close the T-valve on the second pipeline 3, and the liquid enters the lower tank from the upper tank; close the T-valve on the third pipeline 5, open the T-valve on the second pipeline 3, and the liquid is discharged from the lower tank; the first pipeline 1 and the two T-valves on the first pipeline 1 are used to balance the air pressure.

[0028] The gas-liquid separator with a liquid level alarm device provided in this embodiment solves the problem that the water level cannot be visually observed due to the metal shell of the traditional gas-liquid separator. The gas-liquid separator uses a liquid level sensor and an observation hole to observe the water level and realizes the liquid level alarm function.

[0029] The gas-liquid separator with a liquid level alarm device provided in this embodiment has a gas-liquid separation tank 12 that is not completely sealed, and a removable cover plate 7 is provided for easy maintenance; and the gas-liquid separation efficiency is relatively high: the partition plate 10 welded inside the gas-liquid separation tank body shortens the distance from the liquid to the tank body, and the force condition of the liquid remains unchanged (gravity), thereby shortening the liquid separation time and improving the gas-liquid separation efficiency.

[0030] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
