Description

Technical Field

[0001] The utility model relates to the technical field of waste treatment, in particular to a liquid-oxygen-liquid separator. Background Art

[0002] Liquid oxygen is the form of oxygen in liquid state. It has important applications in aerospace, submarine and gas industries. Liquid oxygen is a light blue liquid with strong paramagnetism.

[0003] In the process flow of krypton-xenon refining, the raw liquid oxygen needs to enter the gas-liquid separator in the small cold box of the liquid oxygen pump. The liquid oxygen enters the medium-pressure liquid oxygen pump from the bottom of the gas-liquid separator for pressurization, and then is vaporized into room-temperature krypton-lean xenon gas through the vaporizer. It is then decompressed and sent to the heat exchanger to exchange heat with the krypton-lean xenon gas from the methane removal catalyst furnace to increase its temperature. It is then heated to the temperature required for the catalytic reaction by an electric heater and enters the methane removal catalyst furnace.

[0004] Since liquid oxygen evaporates very quickly at room temperature, the amount of oxygen evaporated in the gas-liquid separator is large, which can easily cause the gas pressure in the gas-liquid separator to be too high and cause damage, and it is also difficult to control the gas delivery rate.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1 The utility model provides a technical solution for a liquid oxygen liquid-liquid separator: a liquid oxygen liquid-liquid separator, comprising a gas-liquid separator 1, a gas outlet 5 is provided at the top of the gas-liquid separator 1, a liquid return port 3 is provided at the center of the bottom of the gas-liquid separator 1, a base 4 is fixedly installed outside the bottom of the gas-liquid separator 1, a vacuum layer 8 is arranged inside the side wall of the bottom of the gas-liquid separator 1, a pressure gauge 6 is connected to one side of the top of the gas-liquid separator 1, a feed port 2 is connected to the bottom of one side wall of the gas-liquid separator 1 and above the base 4, a plurality of umbrella plate separators 7 are evenly installed above the feed port 2 of the gas-liquid separator 1, a baffle 9 is fixedly installed at the top of the gas-liquid separator 1, a foam breaking net 10 is installed on the baffle 9, and a reflux pipe 11 is installed at the connection between the plurality of umbrella plate separators 7 and the side wall of the gas-liquid separator 1.

[0018] Furthermore, the foam breaking net 10 is installed on the baffle 9 in an annular structure, thereby increasing the movement path of the gas and improving the liquid removal effect.

[0019] Furthermore, a plurality of separation holes are provided on the umbrella plate separator 7, and the diameters of the separation holes on the plurality of umbrella plate separators 7 decrease from bottom to top, thereby improving the liquid removal effect.

[0020] Furthermore, a plurality of reflux pipes 11 are installed on the side wall of the gas-liquid separator 1 in a staggered manner to prevent the gas with liquid at the bottom from rising straightly and affecting the liquid removal.

[0021] Furthermore, a refrigerator may be installed in the base 4 in close contact with the side wall of the gas-liquid separator 1 .

[0022] Furthermore, the top and bottom of the gas-liquid separator 1 both adopt arc-shaped structures.

[0023] Embodiment: When the device is in use, the feed port 2 and the liquid return port 3 are connected to the liquid oxygen storage tank. The liquid oxygen in the liquid oxygen storage tank is pumped into the feed port 2 by a feed pump and enters the gas-liquid separator 1. Since part of the liquid oxygen will be vaporized into oxygen during the transmission process, the material entering the gas-liquid separator 1 from the feed port 2 is a gas-liquid mixture of liquid oxygen.

[0024] After the gas-liquid mixture enters the gas-liquid separator 1 from the feed port 2, the gas will rise mixed with some smaller liquid particles. After passing through the umbrella plate separator 7, the liquid particles are filtered, and the gas continues to rise. After being filtered through several layers of umbrella plate separators 7, it reaches the top of the gas-liquid separator 1, and passes through the foam breaking net 10 for the final step of liquid removal filtration before being discharged from the gas outlet 5.

[0025] The liquid particles retained by the filtration flow downward along the wall of the umbrella plate separator 7, fall into the edge of the lower umbrella plate separator 7 or fall into the bottom of the gas-liquid separator 1. The liquid falling into the edge of the lower umbrella plate separator 7 will eventually gather at the reflux pipe 11 under the action of gravity and flow down, and the liquid material will eventually gather at the bottom of the gas-liquid separator 1.

[0026] Due to the temperature of liquid oxygen, a vacuum layer 8 is provided on the inner wall surface at the bottom of the gas-liquid separator 1, which can reduce the heat conduction effect of the wall surface of the gas-liquid separator 1 and maintain the temperature of the liquid oxygen at the bottom of the gas-liquid separator 1. At the same time, a refrigerator can be installed in the base 4 to further control the temperature at the bottom of the gas-liquid separator 1, reduce the gasification of liquid oxygen at the bottom of the gas-liquid separator 1, prevent the liquid oxygen gasification rate at the bottom of the gas-liquid separator 1 from being too high, resulting in an increase in the pressure in the gas-liquid separator 1, and facilitate the control of the oxygen delivery rate.

[0027] The unvaporized liquid oxygen is pumped back into the liquid oxygen storage tank through the liquid return port 3 to complete the cycle.

[0028] When it is necessary to increase the oxygen delivery rate, the efficiency of the liquid delivery pump connected to the feed port 2 can be improved to increase the circulation of liquid oxygen in the circulation system. The faster the liquid oxygen moves, the higher the gasification rate and the higher the gas delivery efficiency.
