<p>The invention concerns a regenerating process and device for a solution of spent dye. The device includes means (12) to separate the dye from a dilutant liquid, called dilutant (14), in order to obtain both a spent dye and the so-called clean dilutant (14), essentially without a spent dye; and means (22) to mix an amount of new dye (24) with the cleaned dilutant (14) in order to obtain a solution of new dye (16'). The device is characterised by the fact that the cleaned dilutant is passed through a refill (26a, 26b, 26c) of new dye (24). The invention allows a solution of dye to be regenerated very simply, in a close circuit, which is very valuable in the field of dye lasers especially for lithotricy.</p> |
