Description

Technical Field

[0001] The utility model relates to the technical field of helium separation and extraction, in particular to a decarbonization device for helium separation and extraction. Background Art

[0002] Helium is widely used in medical, semiconductor manufacturing, optical instruments, aerospace technology and other fields. However, the content of helium in natural gas is very rare. In the process of extracting helium, the separated helium also contains carbon gas, such as carbon dioxide. At this time, a decarbonization device is needed to separate the carbon gas from the helium to obtain high-purity helium.

[0003] A dehydration and decarbonization structure for helium recovery with announcement number CN212881877U is based on an original gas valve, on which a cooling condenser is installed, on which a first gas-water separator is installed, and on which a heat exchanger is connected to the first filter. A second gas-water separator and a second filter are installed on the cooler. The condenser, separator and filter are used in conjunction to condense, filter and separate the gas in turn, thereby realizing the function of decarbonization and purifying the helium.

[0004] There are still problems in the above-mentioned dehydration and decarbonization structure for helium recovery. The decarbonization device is composed of multiple structures. Multiple purification processes are required when decarbonizing helium. The operation is complicated and leads to a decrease in the decarbonization efficiency of helium. Therefore, a decarbonization device for helium separation and extraction is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology, the decarbonization device on the market is composed of multiple structures. Multiple purification processes are required when decarbonizing helium, which is complicated to operate and leads to a decrease in the decarbonization efficiency of helium. The utility model proposes a decarbonization device for helium separation and extraction.

[0006] The technical solution adopted by the utility model to solve its technical problem is: a decarbonization device for helium separation and extraction described in the utility model comprises a condenser body; a decarbonization mechanism is arranged on the inner side of the condenser body, a cooling mechanism is arranged on the circumferential surface of the condenser body, a carbon removal mechanism is arranged on the bottom side of the condenser body, and an air inlet is arranged at one end of the condenser body.

[0008] Preferably, the cooling mechanism includes a cooling tank, an input valve is fixedly installed at one end of the cooling tank, an output valve is fixed at the other end of the cooling tank, the input valve is fixed at one end of the circumferential surface of the condenser body, the output valve is fixed at the other end of the circumferential surface of the condenser body, and a hopper is fixed at the bottom end of the condenser body. By conveying coolant to the inside of the cooling tank, the coolant absorbs the heat inside the condenser body, thereby rapidly reducing the temperature inside the condenser body and solidifying the carbon-containing gas, thereby facilitating subsequent decarbonization treatment.

[0009] Preferably, the carbon discharge mechanism includes a hopper, a box body is fixed at the bottom end of the hopper, a feed port is provided on the circumferential surface of the bottom side of the condenser body, and the feed port is connected to the inner side of the hopper, a limiting groove is provided on the inner side of the box body, a sealing plate is slidably installed on the inner side of the limiting groove, an exhaust valve is fixed to the bottom end of the side surface of the box body, and a sealing ring is fixed at the contact position between the inner side of the box body and the sealing plate.

[0010] The utility model is beneficial in that:

[0011] 1. The utility model adopts a structural design of a decarbonization device for helium separation and extraction. By setting a decarbonization mechanism, gas is transported to the condenser body through a first one-way valve, and water vapor contained in the gas is removed through a waterproof breathable membrane. Then, with the cooperation of a valve seat and a spring, leakage can be prevented during gas transportation. Then, the gas flows inside the spiral blade. As the temperature decreases, the carbon-containing gas liquefies and condenses into a solid. Then, with the cooperation of a filter screen, it is filtered out, thereby realizing the decarbonization treatment of the helium. Then, the purified helium is output by a second one-way valve. The structure is small in size and easy to use, with a higher decarbonization efficiency, which solves the problem of complex structure and low decarbonization efficiency of the existing decarbonization device.

[0012] 2. The utility model adopts the structural design of a decarbonization device for helium separation and extraction.

[0026] Working principle: Helium is widely used in the fields of medical treatment, semiconductor manufacturing, optical instruments, aerospace technology, etc. However, the content of helium in natural gas is very rare. In the process of extracting helium, the separated helium also contains carbon gas, such as carbon dioxide. At this time, a decarbonization device is needed to separate the carbon gas from the helium to obtain high-purity helium. The existing decarbonization device is composed of multiple structures. When decarbonizing helium, multiple purification processes are required. The operation is complicated and leads to a decrease in the decarbonization efficiency of helium. In order to solve this problem, a decarbonization mechanism and a carbon discharge mechanism are set, and the input valve 13 is opened. The coolant is transported to the inside of the cooling tank 12, so that the coolant evaporates on the inside of the cooling tank 12, thereby absorbing the heat on the inside of the condenser body 1 to rapidly cool it down. After that, the evaporated coolant is output from the output valve 14, so that the heat absorbed by it is discharged to the external environment, ensuring that the temperature inside the condenser body 1 drops rapidly and constantly. At this time, gas is delivered to the condenser body 1 through the first one-way valve 3, and water vapor contained in the gas is removed through the waterproof breathable membrane 5. Then, with the cooperation of the valve seat 6 and the spring 8, leakage can be prevented during the gas delivery process. Then, the gas flows on the inside of the spiral blade 10. As the temperature decreases, the carbon-containing gas is liquefied and condensed into a solid. Then, with the cooperation of the filter 11, it is filtered out, thereby realizing the decarbonization of the helium. Then, the purified helium is output by the second one-way valve 4. At the same time, the carbon-containing gas condensed into a solid is discharged from the feed port 15, passes through the hopper 16 and falls onto the surface of the sealing plate 19. Then, the sealing plate 19 is pulled out at one end thereof, so that the solid condensed from the carbon-containing gas falls into the inside of the box body 17. As the temperature rises, it is gasified and removed through the exhaust valve 20, so as to prevent other impurities from being mixed into the helium during the removal of the carbon-containing gas, thereby solving the problem of complex structure and low decarbonization efficiency of the existing decarbonization device.
