Horizontal segment, and several gas vents 15 are equidistantly opened up in the horizontal segment.In gas phase collecting region 2, since hydrogen specific gravity is much smaller than argon
Gas, argon gas thus can natural subsidence and converge in the lower space of gas phase collecting region 2.Here argon gas under the action of air pump 7,
It is returned to liquid-phase collection area 8, and disturbance is applied to the fluid in liquid-phase collection area 8 by uniformly distributed gas vent 15 again and is made
With.From aperture flow out a large amount of argon gas bubbles under buoyancy, towards free surface at do macroscopic motion, make along journey in liquid phase
Still remaining a small amount of fine hydrogen bubble in collecting region 8 is further taken out of under the sweeping along and drive of these argon gas bubbles
Liquid-phase collection area 8 and be precipitated.
To sum up, the hydrogen isolated flows out the device from the hydrogen discharge 3 of the top, and the liquid isolated is by the device
The lowermost liquid storage well 9, via liquid outlet 10 flow out the device, realize and fill the hydrogen in gassiness viscous fluid from liquid phase
Divide isolated purpose.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model, these all will not influence the effect and patent practicability of the utility model implementation.
