Solar evaporator based on biomass hydrogel/nano carbon material and application of solar evaporator

Abstract

The invention relates to a biomass hydrogel / nano carbon material-based solar evaporator, which comprises a heat collection evaporator, a condenser and a water collector; the heat collection evaporator is used for converting solar radiation energy into heat energy to provide a heat source and heating seawater or water to be purified by using the heat source to generate steam; wherein the heat collection evaporator comprises a main body material and a fixator used for fixing the main body material, the main body material is a main body supporting framework with polyurethane (PU) sponge as a main body, and the supporting framework is filled with biomass hydrogel / nano carbon materials. The solar evaporator has a high evaporation rate, has a good removal effect on ions and organic dyes in seawater, and solves the bottleneck problem that the efficiency is reduced due to salt crystallization caused by long-term operation of a conventional evaporator. According to the technology, efficient evaporation of water and long-term operation of the evaporator are achieved, the water treatment effect is obvious, and long-term operation can be achieved. In addition, the evaporator is low in manufacturing cost, and cyclic utilization of natural resources is achieved.

Description

technical field [0001] The invention relates to a solar evaporator based on biomass hydrogel / nano carbon material and its application, which belongs to the technical fields of chemistry and environment. Background technique [0002] With the increasing shortage of fresh water resources, the use of unconventional water sources as a supplement to fresh water resources has received widespread attention. As a clean energy source, whether solar energy can be efficiently used to generate clean water has attracted the attention of many scholars. Solar light hot water evaporation is to use solar energy to heat water into water vapor and then collect it. The advantage of solar evaporators is that they can be used to desalinate seawater or produce fresh water stably in remote and backward areas without energy consumption. Since the natural evaporation is very slow, in order to increase the evaporation rate, several problems need to be solved when designing solar evaporators: ① Impro...
