Abstract

The invention discloses a plant bionic solar distiller, and belongs to the technical field of solar heat utilization and water treatment. The plant bionic solar distiller mainly comprises a bionic hydrophilic root, a bionic stem, a bionic petiole, a bionic vein and a bionic blade. The bionic leaf refers to the physiological structure of a green plant leaf, and the internal structure of the bionic leaf comprises a light-transmitting plate, a heat insulation grid, a heat absorption plate, a hydrophilic fiber membrane, bionic leaf veins, a distillation membrane, a condensation interlayer and a condensation plate. In the desalination process, solar rays penetrate through the light-transmitting plate, are absorbed by the heat absorption plate, are converted into heat energy and heat seawater in the hydrophilic fiber membrane, evaporated water vapor penetrates through the distillation membrane and is condensed into fresh water by the condensation plate below, and the process refers to the transpiration of green plants. And meanwhile, the plant bionic solar distiller simulates the water spitting phenomenon of the plant by utilizing the water potential difference and the capillary force of the hydrophilic material, so that the accumulation of salt on the evaporation surface is avoided. The plant bionic solar distiller has the advantages of being compact in structure, easy and convenient to operate and capable of running continuously.

Description

[0001] Technical field [0002] The invention belongs to the technical field of solar heat utilization and water treatment, and in particular relates to a plant bionic solar distiller. Background technique [0003] Facing the increasingly severe shortage of fresh water and fossil energy, using solar energy to desalinate seawater to produce fresh water is a low-carbon and environmentally friendly solution. Interface solar seawater desalination technology can greatly improve the thermal response rate and reduce the heat loss in the heating process by concentrating solar heat on the gas-liquid surface. It is considered to be a promising seawater desalination technology. However, during the evaporation process of interfacial seawater desalination, the accumulation of salt will block the water delivery path and reduce the heat absorption rate of the evaporation surface. key to efficiency. [0004] Green plants in nature can regulate the temperature of their leaves by continuously...
