[0002] In wet-process phosphoric acid production plants, the water ring vacuum pumps in the vacuum system of each process play an extremely important role. Currently, the exhaust pipes of the water ring vacuum pumps in the vacuum system are designed for direct discharge. During the start-up and shutdown of the equipment, water vapor media inside the equipment will be sprayed out from the exhaust pipes, polluting the surrounding environment and posing significant safety and environmental hazards. Utility Model Content
[0003] The purpose of this invention is to provide a water ring vacuum pump gas-liquid separator for a wet-process phosphoric acid production device, which can effectively separate the gas and liquid media in the exhaust pipe of the water ring vacuum pump, thus completely solving safety and environmental protection issues.
[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a water ring vacuum pump gas-liquid separator for a vacuum system in a wet-process phosphoric acid production apparatus, comprising a separation shell and an exhaust port connector. The separation shell contains, from bottom to top, a first baffle plate, a second baffle plate, and a third baffle plate. The first and second baffle plates are fixed to the same side wall within the separation shell, while the third baffle plate and the exhaust port connector are fixed to the opposite side wall within the separation shell. One end of the plate is a fixed end, and the other end is a free end. The fixed ends of the first baffle plate, the second baffle plate, and the third baffle plate are fixed to the side wall inside the separation housing. The first baffle plate, the second baffle plate, and the third baffle plate are inclined downward from their fixed ends to their free ends. The exhaust port pipe is used to connect the exhaust pipe of the water ring vacuum pump to the outside. The exhaust port pipe is inserted inward between the first baffle plate and the second baffle plate. An exhaust pipe is fixedly connected to the top of the separation housing, and a return pipe is fixedly connected to the bottom of the separation housing.
[0005] In one embodiment, the angle between the first baffle and the vertical plane is 85°.
[0006] In one embodiment, the angle between the second baffle and the vertical plane is 87°.
[0007] In one embodiment, the third baffle plate makes an angle of 87° with the vertical plane.
[0008] In one embodiment, the fixed ends of the first baffle, the second baffle, and the third baffle are welded and fixed to the side wall of the separation shell.

[0012] The present invention achieves the following technical advantages over the prior art: This utility model provides a water ring vacuum pump gas-liquid separator for a wet-process phosphoric acid production apparatus. The gas-liquid medium in the exhaust pipe of the water ring vacuum pump is introduced into the separation shell through the exhaust port connector. It collides with the inner wall of the separation shell and undergoes initial gas-liquid separation under gravity. The liquid medium then flows downwards through the side wall of the separation shell and the first baffle plate, and returns to other equipment in the system through the return pipe. Due to inertia, a small amount of liquid medium moves with the upward-flowing gas. Under the obstruction of the second and third baffle plates and gravity, the gas and liquid medium separate again. The liquid medium flows downwards through the second and third baffle plates and the side wall of the separation shell to the bottom of the separation shell, and returns to other equipment in the system through the return pipe. The gas is discharged through the exhaust pipe at the top, achieving complete separation of the gas and liquid medium and thoroughly solving safety and environmental protection issues.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] The purpose of this invention is to provide a water ring vacuum pump gas-liquid separator for a wet-process phosphoric acid production device, which can effectively separate the gas and liquid media in the exhaust pipe of the water ring vacuum pump, thus completely solving safety and environmental protection issues.
[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] like Figures 1-2 As shown, this embodiment provides a water ring vacuum pump gas-liquid separator for a wet-process phosphoric acid production apparatus vacuum system, including a separation housing 1 and an exhaust port connector 2. Inside the separation housing 1, from bottom to top, are arranged a first baffle plate 3, a second baffle plate 4, and a third baffle plate 5. The first baffle plate 3 and the second baffle plate 4 are fixed to the same side wall inside the separation housing 1. The third baffle plate 5 and the exhaust port connector 2 are fixed to the other side wall inside the separation housing 1, opposite to the first baffle plate 3 and the second baffle plate 4. One end of the first baffle plate 3, one end of the second baffle plate 4, and one end of the third baffle plate 5 are all fixed ends. The other ends of the first baffle plate 3, the second baffle plate 4, and the third baffle plate 5 are all free ends. The fixed ends of the first baffle plate 3, the second baffle plate 4, and the third baffle plate 5 are fixed to the side wall inside the separation housing 1. The first baffle plate 3, the second baffle plate 4, and the third baffle plate 5 are inclined downward from their fixed ends to their free ends. The exhaust port pipe 2 is used to connect the exhaust pipe of the water ring vacuum pump to the outside. The exhaust port pipe 2 is inserted inward between the first baffle plate 3 and the second baffle plate 4. The top of the separation housing 1 is fixedly connected to the exhaust pipe 6, and the bottom of the separation housing 1 is fixedly connected to the return pipe 7.
[0020] In use, the exhaust pipe of the water ring vacuum pump is connected to the exhaust port connector 2. The gas-liquid medium in the exhaust pipe of the water ring vacuum pump is introduced into the separation shell 1 through the exhaust port connector 2. It collides with the inner wall of the separation shell 1 and undergoes preliminary gas-liquid separation under the action of gravity. Then, the liquid medium flows downward through the side wall of the separation shell 1 and the first baffle plate 3, and flows back to other equipment in the system through the return pipe 7. Under the action of inertia, a small amount of liquid medium will move with the upward-flowing gas. Under the blocking effect of the second baffle plate 4 and the third baffle plate 5 and the action of gravity, the gas-liquid medium will separate again. The liquid medium flows downward through the second baffle plate 4, the third baffle plate 5 and the side wall of the separation shell 1 to the bottom of the separation shell 1, and flows back to other equipment in the system through the return pipe. The gas is discharged from the exhaust pipe 6 at the top, realizing the complete separation of gas and liquid medium and completely solving the safety and environmental protection issues.
[0021] In this embodiment, the first baffle 3 forms an angle of 85° with the vertical plane. The second baffle 4 forms an angle of 87° with the vertical plane. The third baffle 5 forms an angle of 87° with the vertical plane. In actual use, other tilt angles can be set according to the actual situation.
[0022] In this embodiment, the fixed ends of the first baffle plate 3, the second baffle plate 4, and the third baffle plate 5 are welded and fixed to the side wall of the separation shell 1 to ensure the stability and reliability of the connection.
[0023] In this embodiment, the exhaust pipe 6 is located above the third baffle plate 5 and close to the fixed end of the third baffle plate 5, which can increase the baffle distance of the gas-liquid medium and improve the gas-liquid separation effect.
[0024] In this embodiment, the return pipe 7 is fixed to the side wall of the separation housing 1 and located below the first baffle plate 3 so that the separated liquid can be discharged smoothly.
[0025] In this embodiment, the separation shell 1, exhaust port pipe 2, first baffle 3, second baffle 4, third baffle 5, exhaust pipe 6, and return pipe 7 are all made of steel plate, such as Q235 steel plate. The working pressure is designed for atmospheric pressure, which makes it easy to manufacture, has a stable and reliable structure, low manufacturing cost, and is easy to maintain.
[0026] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
