A suspended distillation device based on nanomaterials and solar energy

Abstract

The invention belongs to the technical field of water treatment and discloses a suspension type distillation device based on a nanomaterial and solar energy. The distillation device comprises an uncovered water tank, a water tank cover, nano cloth and a water collection component, wherein a liquid storage tank is arranged below the uncovered water tank; the water tank cover is arranged on the uncovered water tank; part of the nano cloth is fit with the lower side of the water tank cover; part of the nano cloth is immersed in liquid in the liquid storage tank; the water collection component comprises a condensate tank; the condensate tank is an open hollow structure and is suspended on the liquid in the liquid storage tank; and a capillary structure is arranged on the surface on one side, facing towards the water tank cover, of the condensate tank. The device can achieve heat exchange of steam and water to be evaporated on the basis that a solar energy resource is made full use of; condensate water is absorbed and transported quickly by a capillary action at the same time; the scattering of sunlight by the condensate water is effectively avoided; and a utilization ratio of the solarenergy is further increased on the basis that the efficiency of water purification treatment is significantly improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment such as solar desalination / purification of sewage, and more specifically relates to a suspended distillation device based on nanomaterials and solar energy. 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 condense steam...

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, most of the existing technologies use air convection at the glass cover to reduce the temperature of water vapor to achieve condensation. However, during the condensation process, water vapor will release a lot of heat, and solar energy also provides a lot of heat. making condensation less effective
