Description

Multistage distiller Technical Field The utility model relates to the technical field of distillers, in particular to a multistage distiller. Background In recent years, solar photo-thermal driven interfacial evaporation technology has been widely focused by students, and the solar evaporation efficiency of an interfacial distiller can reach more than 80% by synthesizing new photo-thermal conversion materials and constructing an efficient thermal management strategy. In solar interfacial evaporation systems of conventional construction, the vapor generated by the distiller condenses and collects on the top glass cover surface, and this condensation design results in the latent heat of the vapor being totally dissipated to the environment and not recovered. On this basis, some scholars propose a multi-stage distillation device, and the structure of multi-stage distillation uses the latent heat released by steam condensation to strengthen the evaporation process, so that the latent heat released by steam can be recycled. For example, chiavazzo et al propose the initial use of the vapor enthalpy cycle method to produce passive evaporation devices with heat energy utilization efficiencies exceeding 100%, which are as high as 3kg m -2h-1 at one solar irradiation intensity (Chiavazzo, et al, 2018). Xu et al fabricated a ten-stage salt-free evaporator prototype using low cost materials and achieved 385% solar-to-vapor conversion efficiency and 5.78kg m -2h-1 (Xu, 2020) of the original record under a solar light irradiation, further reducing heat loss and significantly improving fresh water production from the device. However, the multi-stage device only uses the top surface to receive light, and cannot absorb sunlight from multiple directions, so that the actual water production efficiency is different from the theoretical efficiency to limit the commercial application of the multi-stage device, in addition, the prior multi-stage system has marginal effect, the latent heat of steam is gradually reduced along with the increase of the stage number, the utilization rate of the device is also reduced, and the heat loss of the side wall is an important factor influencing the efficiency of the device in the aspect of heat transfer. Therefore, the application provides a hemispherical multistage evaporator which receives light in all directions and can reduce heat loss of the side wall.
