ADSORPTIVE PLANT Russian patent published in 1996 - IPC

FIELD: medical and biological engineering. SUBSTANCE: plant consists of two parallel mounted columns with adsorbent connected with gas-feed pipeline by branch pipes, of throttle device and regulating unit consisting of unit of valves and unit for valve control. Unit of valves is equipped with additional valve for pressure leveling mounted between inlet branch pipes of columns. Unit for valve control has four switching members and three air relays of quick dropping. The outputs of first, second and third switching members are connected with inputs of first, second and third air relays of quick dropping. The output of first air time relay is connected with inputs of first and second switching members. The output of second air time relay is connected with input of third switching member whose output is connected with additional valve of pressure leveling. The output of third air time relay is connected with inputs of first and fourth switching members. The output of fourth switching member is connected with inputs of unit of valves and the input is connected with output of first switching member. EFFECT: enhanced quality of gas cleaning. 3 dwg
