The invention discloses an online recovery and purification system for waste helium in an aerostat. The online recovery and purification system comprises a helium gas compressor, an adsorption drying device, a membrane osmosis purifier and a helium gas purity analyzer, wherein an inlet of the helium gas compressor is connected with the aerostat, an outlet of the helium gas compressor is communicated with the adsorption drying device, an outlet of the adsorption drying device is connected with the membrane osmosis purifier, an outlet of the membrane osmosis purifier is communicated with the aerostat, the helium gas purity analyzer detects the purity of gas at the outlet of the membrane osmosis purifier, the membrane osmosis purifier is also communicated with one end of a three-way valve, a second end of the three-way valve is communicated with an inlet of the helium gas compressor, and a third end of the three-way valve is not occupied.
Description
technical field [0001] The invention relates to the field of helium recovery devices, in particular to an online recovery and purification system for waste helium in an aerostat. Background technique [0002] The interior of the aerostat is filled with helium, which provides buoyancy to the aerostat, making it lift into the air and float statically at a certain height in the sky. The mooring time of the aerostat is determined by the buoyancy generated by filling the helium inside. If the purity of the helium inside decreases, the buoyancy generated by it will decrease, and the mooring time will be shortened, and even lead to floating. Therefore, the purity of helium is very important for the high-altitude work of the aerostat. While the aerostat floats at high altitude for a long time, the sphere itself has the phenomenon of gas infiltration and leakage, and the internal helium is polluted by the infiltrated air, resulting in a decrease in purity, which in turn affects the ...
