Abstract
A filter including multiple tanks connected in series by connecting ducts. In the filter a flow of gaseous flows encounters multiple obstacles in it, an effect of which is efficiently to block constituents with heaviest molecular weight, without substantially hindering diffusion of lighter constituents. This may be obtained by internal baffles, or by a bank of finer ducts, for example at an inlet of the filter. Such a filter may find application to separation of hydrogen and radon produced by nuclear waste.
Claims9
A selective gas filter in which a flow of a heavy constituent in a blend of gases is hindered more than that of a light constituent, so as to slow and retain the heavy constituent to a greater degree, the filter comprising:
- multiple tanks arranged in series, and connected to one another by ducts;
- a single outlet duct for the gases;
- an interior of the filter forms a single internal path for the flow, thus there is no separation of the gases by a flow fork, and the tanks are occupied by successive baffles imposing a winding path.
