DEVICE FOR ION-EXCHANGE PURIFICATION OF WATER Russian patent published in 2002 - IPC

FIELD: procedure of water purification by the ion- exchange method, applicable in boiler plants. SUBSTANCE: the device has a source water feed pipe-line with a pump, whose pressure line is connected to the input of a filter with reagent, actuator valve installed at the filter outlet, treated water pressure line, recirculation line with an actuating mechanism, recirculation flow control circuit comprising a flow transducer installed in the pump pressure line, and a governor whose inlet is connected to the flow transducer, and the outlet is connected to the actuating mechanism, connected to the filter inlet is a flexible pipe-line, step-like in filter height attached to which through a pipe connection are flat elastic rings with expansible packings, on whose inner surface provision is made for spiral curvilinear guides, has expansible packings tangentially connected to the flat elastic rings, installed before them in the cavity of the flat elastic rings are bimetallic pulsers made in the form of at least four bent blades freely fitted on an axle, whose opposite ends form an angle of 90 deg. EFFECT: enhanced efficiency of ion exchange and reduced consumption of reagents. 3 dwg
