ION-EXCHANGE APPARATUS Russian patent published in 1995 - IPC

FIELD: cleaning matters from contaminations. SUBSTANCE: aid for improving exchange capacity of ion exchanger and solution removing system are integrated functionally and made in form of air-proof chamber, which is fixed inside the case and connected with systems for feeding working substance and collecting solution treated. One end of flexible hose is attached along the perimeter of hole, made in case. The other end of the hose is fixed along the perimeter of branch pipe, inside which elastic torus is mounted to be air-proof. The torus is embraced by flexible link. One end of the link is fixed inside branch pipe, the other one passes through central hole of the torus and connected with driving drum, which drum is mounted inside air-proof chamber. Reverse valve is mounted in wall of the branch pipe for passing solution worked through. Reciprocal displacement of branch pipe together with the hose provides alternate increment and decrease in pressure of medium, at which pressure sorption process is intensified, and exchange capacity of ion exchanger increases. EFFECT: improved efficiency of operation. 1 dwg
