A multi-stage evaporation system enhanced by a gravity-reduced field consists of evaporation structures of multiple stages. There are three different operation modes, namely, a serial-connected air and parallel-connected solution mode, a serial-connected air and serial-connected solution mode, and a parallel-connected air and serial-connected solution mode. In the evaporation chambers, the solution directly contacts the air to transfer the heat and mass. The solution is sprayed on the rotating filling material, and is uniformly distributed under the action of the gravity-reduced field, which enhances the heat and mass transfer. The solution is gasified by absorbing the heat energy thereof. Meanwhile, the air can carry more water vapor after being heated by the solution and thus having an increased temperature, and take away the gasified solution, thereby achieving the purpose of evaporation. |
