AI Technical Summary

Technical Problem

Existing helium recovery devices operate under negative pressure, causing outside air to seep in, diluting the helium, resulting in resource waste and high costs.

Method used

By maintaining a slightly positive pressure in the helium recovery system, using pressure sensors and multiple valves in tandem, the system prevents outside air from seeping in, and achieves efficient recycling of helium through a compressor and a high-pressure tank.

Benefits of technology

It significantly reduces helium consumption, lowers production costs, improves helium recovery efficiency, extends equipment life, and realizes both environmental and economic benefits of helium resources.
