Problems solved by technology

[0004] Traditional solar stills use lenses or mirrors to absorb solar energy. These materials cost $200 per square meter, and the energy conversion efficiency is only about 50%, and the work efficiency is lower at night and when the solar radiation is not ideal; and the stills are complicated to manufacture , poor durability, unable to scale up

Embodiment 1

[0025] Add 1.25g of ferric chloride into 50mL of absolute ethanol to obtain a brown ferric chloride solution (25mg / mL); dissolve 2g of pyrrole monomer in 78mL of absolute ethanol to obtain a pyrrole solution; product, see figure 2 , cut into a cylindrical structure when used, with an outer diameter of 80mm and a height of 30mm), soaked in ferric chloride solution (the thickness of the soaked part is 20% of the total thickness of the sponge), soaked for 5 minutes, took out the sponge and put it in a vacuum drying oven for 80 After drying at ℃ for 90 minutes, take it out, drop all the pyrrole solution on the part of the sponge soaked in ferric chloride, and put it in a vacuum drying oven again to dry at 105 ℃ for one hour; then take out the sponge, and soak the part of ferric chloride 7 ( figure 1 Middle) has turned black, and the other parts have not changed color, which is a porous water-absorbing material.

[0026] Two containers of the same size, A and B, were prepared. On...

Embodiment 2

[0029] Add 1.25g of ferric chloride to 50mL of absolute ethanol to obtain a brown ferric chloride solution (25mg / mL), and cut the sponge (melamine sponge, a commercially available product) into a cylindrical structure (outer diameter 80mm, height 30mm) ,See figure 2 , the same as the sponge in Example 1) soaked in ferric chloride solution (the thickness of the soaked part is 20% of the total thickness of the sponge), soaked for five minutes, took out the sponge and put it in a vacuum drying oven at 80°C for 90 minutes and then took it out , at this time the ethanol is completely volatilized; then put 5ml of pyrrole into the vacuum drying oven and keep the temperature at 80°C. The high temperature of the drying oven makes the pyrrole evaporate, and the pyrrole vapor will treat the whole sponge. Take out the sponge after 1 hour, and the sponge is treated with ferric chloride The treated part becomes black (MPF part), while the untreated part remains white in color (MF part, whi...

Embodiment 3

[0034] Prepare a transparent cover, a treatment chamber, and a sewage chamber according to conventional methods. The opening of the sewage chamber is the sewage inlet, and the conventional method of the treatment chamber is equipped with a clean water outlet pipe (4mm inner diameter, which can be covered with a hose); put porous water-absorbing materials into the sewage chamber. , the part containing polypyrrole faces upward, the sewage chamber is placed in the treatment chamber, and the transparent cover is placed on the treatment chamber to form a seal, so that an all-weather solar evaporation water purifier is obtained.

[0035] Prepare four identical all-weather solar evaporative water purifiers, two of which do not contain porous water-absorbing materials and only have solutions, defined as water purifier A and water purifier B, and two of which contain porous water-absorbing materials, defined as water purifier C , Water purifier D, the simulation demonstration of sewage ...

Abstract

The invention provides an all-weather solar evaporative water purifier. The all-weather solar evaporative water purifier comprises a transparent cover, a treatment cavity, a sewage cavity and a porouswater absorption material, wherein the porous water absorption material is located in the sewage cavity, and the sewage cavity is located in the treatment cavity; the transparent cover covers the treatment cavity; the sewage cavity is provided with a sewage inlet; and the treatment cavity is provided with a purified water outlet pipe. The efficient photothermal conversion performance, heat insulation performance and hydrophobic performance of black sponge and the good water absorption performance of a hydrophilic sponge material are fully utilized, so the evaporative water purifier has efficient solar evaporation efficiency and efficient self-evaporation effect. According to a preparation method in the invention, sunlight or simulated sunlight serves as a light source, other energy sources are not needed, so the method is environmentally friendly; and operation is easy, convenient and rapid. Wide space is provided for manufacturing an efficient, large-scale and durable solar steam system through integrated structure design of commercial polymer foam, and the evaporative water purifier can be widely applied to the industries of steam power generation, sewage treatment, seawater desalination and the like.

Description

technical field [0001] The invention relates to an all-weather water evaporation system utilizing solar energy, which can be widely used in petrochemical, pharmaceutical, sewage treatment, seawater desalination, food and other industries. Background technique [0002] Water is the basic material for the survival and development of human society, but the fresh water existing in rivers, lakes and groundwater that can be directly used by humans currently only accounts for 0.36% of the earth's water resources. With the rapid development of human society, water pollution has become a global problem. On the one hand, with the development of world urbanization and the gradual improvement of people's living standards, the discharge of domestic sewage is increasing; on the other hand, the development of industry has led to an increasing discharge of sewage, and the composition of sewage is becoming more and more complex. , not only contains a large amount of inorganic salts, but als...
