Method and apparatus for filtering atomic or molecular contaminants from a gas

摘要: Tubular or rod shaped pieces of a filter material having holding-back capability with respect to the contaminant are arranged in interior containing cylinder through which gas flows, so as provide passages for flow along surface pieces, latter being typically disposed their long dimension parallel direction flow. For prescribed pressure loss filter, maximum value should be obtained quantity that is equal length times second Stanton number divided by hydraulic diameter, term four volume space not occupied contact gas. The quotient transfer coefficient and velocity Favorable escape coefficients made available relatively low drop, can interposed main cooling line nuclear reactor removing contaminants radioactive caesium.
