CONCENTRATING APPARATUS

摘要

An apparatus for concentrating a dilute solution comprising a heat receiving thin plate which has a good thermal conductivity and is provided on its rear surface not facing a heat source with a liquid absorbing layer for absorbing a solution supplied thereto for concentration, and at least one condensation thin plate which has a good thermal conductivity and is provided with a liquid absorbing layer on at least one surface thereof, the heat receiving plate and the condensation plate or plates being arranged in parallel spaced relationship with each other and each of them being partly formed with at least one groove for supplying the solution to be concentrated to the liquid absorbing layers. A dilute solution supplied to and impregnated in the liquid absorbing layers through the grooves is concentrated by the heat supplied to the heat receiving plate or the latent heat of condensation released to the condensation plate.
