Abstract
The invention belongs to the field of water purification equipment, particularly discloses a multi-stage plate-type solar membrane distillation system, and aims to solve the problem that an existing single-stage plate-type solar membrane distillation system does not utilize heat released by water vapor condensation. The multi-stage plate-type solar membrane distillation system comprises at least two single-stage plate-type solar membrane distillation devices, and in any two adjacent stages of single-stage plate-type solar membrane distillation devices, a condensation chamber of the previous stage of device is connected with a raw water chamber of the next stage of device through a heat conduction piece. Thus, heat released by condensation of water vapor in the condensation chamber of the previous stage of device can be transmitted to raw water in the raw water chamber of the next stage of device through the heat conduction piece, evaporation of the raw water is facilitated, condensation of the water vapor is facilitated, the heat released by condensation of the water vapor can be recycled, and the energy consumption is reduced. And compared with a single-stage system, the multi-stage system has higher energy efficiency and higher water yield per unit area.
Description
technical field [0001] The invention belongs to the field of water purification equipment, and in particular relates to a multi-stage plate type solar film distillation system. Background technique [0002] In today's world, hundreds of millions of people still drink untreated surface water or groundwater because they do not have the most basic water treatment facilities. In addition, the areas hit by natural disasters are often cut off from water and electricity, and the water supply for the victims cannot be guaranteed. Therefore, there is a great need for a simple and economical decentralized water purification device that is not driven by electricity. Since many water-scarce regions have abundant sunlight, technologies that use solar radiation to evaporate and condense raw water to collect distilled water are promising. [0003] For example, the journal ACS EST Engg. 2021, 1, 4, 770-779 and the US patent application US20210017048A1 disclose a single-stage panel solar f...
