A solar still that collects condensate based on capillary action

Abstract

Belonging to the technical field of water treatment, the invention discloses a capillary action-based solar distiller for collecting condensate water. The solar distiller comprises one or more solar distiller substructures superimposed vertically in order. Specifically, single solar distiller substructure comprises a bottom uncovered water tank, water collecting tanks, a condensation plate and a water storage baffle plate. The bottom uncovered water tank contains a liquid storage tank, and the condensation plate comprises a condensation surface and vertical droplet surfaces. The solar distiller provided by the invention can realize multi-stage utilization of water vapor waste heat on the basis of full utilization of solar energy resources, and at the same time can achieve fast absorption and transportation of condensate water by capillary action and aggregation of the condensate water, and can prevent sunlight scattering by water droplets from lowering the system efficiency, thus further enhancing the solar energy utilization on the basis of remarkably improving the water purification treatment efficiency. Moreover, the solar distiller also has the advantages of more compact structure, convenient operation, stronger environmental adaptability, low water purification cost, etc.

Description

technical field [0001] The invention belongs to the technical field of water treatment such as solar seawater desalination / purification of sewage, and more specifically relates to a solar distiller for collecting condensed water based on capillary action. Background technique [0002] Drinking water is one of the major issues facing the world, most of the health problems are caused by the lack of clean drinking water. In recent decades, insufficient rainfall around the world has led to an increase in the salinity of water bodies. Environmental pollution has further exacerbated the lack of clean fresh water. One of the most important means to solve the shortage of fresh water is seawater desalination. Generally speaking, seawater desalination technologies can be roughly divided into two categories: thermal desalination technology and membrane desalination technology. In thermal desalination technologies, fresh water is obtained by heating seawater to evaporate water and co...

AI Technical Summary

Problems solved by technology

[0004] However, there are still many problems with nanotechnology-based stills

On the one hand, because the water vapor in the distiller condenses directly on the glass cover to form condensed water, the condensed water scatters the incoming sunlight, thereby greatly reducing the use of solar energy. At the same time, the condensed water condenses under gravity Under the action, it drips into the seawater or sewage container, resulting in poor recovery of condensed water

On the other hand, the existing technology adopts a single-stage distiller, which cannot realize multi-stage utilization of solar energy, and at the same time, cannot realize the utilization of heat dissipation of seawater or sewage heated by solar energy. Although the evaporation efficiency is 80-90%, the comprehensive system Efficiency is only less than 30%
