Description

Technical Field

[0001] This utility model relates to the field of helium purification, and in particular to a high-pressure crude helium ultra-low temperature adsorption purification device. Background Technology

[0002] Helium, a scarce inert gas, possesses an extremely low boiling point, excellent chemical stability, and thermal conductivity, making it indispensable in high-end fields such as natural gas extraction, aerospace, semiconductor manufacturing, and low-temperature superconductivity. In the natural gas extraction industry, helium often exists as a by-product in natural gas, and its recovery and utilization can be achieved through natural gas helium extraction processes.

[0003] A search of Chinese patents revealed publication number CN220405209U, which discloses a helium cryogenic adsorber, relating to the technical field of helium adsorption devices. The adsorber includes an adsorber housing with a vacuum tube, a raw material gas inlet pipe, a regenerated gas outlet pipe, a regenerated gas inlet pipe, and a product gas outlet pipe. A heat exchange system and an adsorber body are fixed inside the adsorber housing. A cold-insulating jacket is provided on the outer wall of the adsorber body, and the interior of the adsorber body is filled with adsorbent packing material. The heat exchange system includes an adsorber heat exchanger, several intermediate circulation heat exchangers, and a feed / discharge heat exchanger. The adsorber heat exchanger is connected to the adsorber body, and the feed / discharge heat exchanger is connected to the raw material gas inlet pipe and the product gas outlet pipe. Several intermediate circulation heat exchangers connect the adsorber heat exchanger and the feed / discharge heat exchanger. This invention improves the heat exchanger efficiency by providing a cold-insulating jacket on the outer wall of the adsorber body and by incorporating multiple heat exchangers.

[0004] Existing purification devices are inconvenient for replacing adsorption materials. Generally, purification devices use molecular sieves and activated carbon for adsorption. The molecular sieves and activated carbon are located inside the tank. When replacing them, the tank needs to be disassembled, and then the molecular sieves and activated carbon need to be removed and replaced. Disassembly requires removing and installing a large number of bolts, which greatly increases the workload, reduces the efficiency of replacement, and is inconvenient to use, thus reducing practicality. In order to solve the above problems, we propose a high-pressure crude helium ultra-low temperature adsorption and purification device. Utility Model Content
