<p>PURPOSE:To enable a gas to contact with an absorbing solution efficiently, by introducing an unclean gas into a filter rotated and in contact with the absorbing soln. CONSTITUTION:An unclean gas produced in evaporation process of a photographic waste solution is led to the pipe 108. Passing the introduction part 105 of a container 106 contg. a gas absorbing solution and the connecting pipe 106c of the rotary filter 106, the gas is introduced into the hollow of the filter body 106a. While passing through the filter body 106a, the gas comes in contact with the absorbing solution cleaned, and exhausted through 104 to outside. The rotary filter 106 is rotated by a motor 107 so that the filter body 106a can be impregnated sufficiently with the absorbing soln. When the absorbing ability of the solution lowers, the solution is drawn out and a new absorbing solution is able to be supplied from upwards.</p> |
