Abstract

The invention discloses a plant bionic solar distiller, which belongs to the technical field of solar heat utilization and water treatment. The device mainly includes bionic hydrophilic roots, bionic stems, bionic petioles, bionic veins, and bionic leaves. The bionic leaf refers to the physiological structure of green plant leaves, and its internal structure includes a light-transmitting plate, a heat-insulating grid, a heat-absorbing plate, a hydrophilic fiber film, a bionic vein, a distillation film, a condensation interlayer, and a condensation plate. During the desalination process, sunlight passes through the light-transmitting plate, is absorbed by the heat-absorbing plate and is converted into heat energy and heats the seawater in the hydrophilic fiber membrane. The evaporated water vapor passes through the distillation membrane and is condensed into fresh water by the condensation plate below. This process refers to Transpiration of green plants. At the same time, the device uses the water potential difference and the capillary force of the hydrophilic material to simulate the water spit phenomenon of plants and avoid the accumulation of salt on the evaporation surface. The inventive device has the characteristics of compact structure, easy operation and sustainable operation.

Description

[0001] Technical field [0002] The present invention belongs to the field of solar thermal utilization and water treatment technology, specifically relates to a plant bionic solar still. Background [0003] Faced with the growing shortage of fresh water and fossil fuels, the use of solar energy for desalination to produce fresh water is a low-carbon and environmentally friendly solution. Interface solar seawater desalination technology greatly improves the thermal response rate and reduces the heat loss during the heating process by concentrating solar heat on the gas-liquid surface, and is considered a promising seawater desalination technology. However, during the evaporation process of interface seawater desalination, the accumulation of salt will block the water transmission path and reduce the heat absorption rate of the evaporation surface, so designing a structure that can efficiently supply water and drain salt is the key to improving the water production efficiency of int...
