DIAPHRAGM APPARATUS Russian patent published in 1994 - IPC

FIELD: diaphragm separation of chemically active liquids and gases. SUBSTANCE: casing accommodates bank of diaphragm members whose ends are fixed in movable and stationery tube plates. Movable plate has shell whose axial bore communicates with separated mixture pipe union; circular separating member in the form of metal diaphragm is connected over its external perimeter with casing and over its inner perimeter, with shell bottom near pipe union. Its distance δ from end cover surface is found from inequality d < 0,8(δ_s - Δ_e), where Δ_e is maximum bend of diaphragm, δ_s is maximum change in diaphragm member length. EFFECT: improved design. 4 cl, 3 dwg
