Embodiment 1

[0046] Example 1: Nano CuS sponge is used as photothermal conversion material, and ordinary glass is used to form a distilled water collector

[0047] Place the nano-copper sulfide sponge (10*10*0.3cm) on the surface of the foamed polyethylene wrapped by the clean cloth to form a light absorber, then put it into the water storage tray, use ordinary glass to form a distilled water collector, and seal the inclined cover plate . The simulated solar light was irradiated on the inclined cover plate for 4 hours continuously. A large amount of mist formed by fine water vapor appeared on the glass wall of the collector, and the transmittance of sunlight was greatly reduced. The purified water collected at the water outlet was used to calculate the production. rate, the yield of desalinated seawater is 0.91kg / m 2 / h, the ion concentration of the produced fresh water meets the World Health Organization (WHO) drinking water standard, and the photothermal conversion efficiency reaches 61...

Embodiment 2

[0048] Example 2: The CuS foam of the present invention is used as a light-to-heat conversion material, and a distilled water collector is composed of ordinary glass

[0049] Place the CuS foam (10*10*0.3cm) on the surface of the foamed polyethylene wrapped in a clean cloth to form a light absorber, then put it into the water storage tray, use ordinary glass to form a distilled water collector, and seal the inclined cover. When the simulated solar light was irradiated on the inclined cover plate for 4 hours continuously, mist formed by a large amount of fine water vapor appeared on the glass wall of the collector, and the transmittance of sunlight was greatly reduced. The yield of desalinated seawater is 0.97kg / m 2 / h, the ion concentration of the produced fresh water meets the WHO drinking water standard, and the light-to-heat conversion efficiency reaches 65%.

Embodiment 3

[0050] Example 3: Nano CuS sponge as photothermal conversion material, using SiO 2 AR-coated glass forms the distilled water collector

[0051] Place the nano CuS sponge (10*10*0.3cm) on the surface of the foamed polyethylene wrapped by the clean cloth to form a light absorber, and then put it into the water storage tray, and use SiO 2 AR-coated glass forms the distilled water collector and seals the beveled cover. The simulated solar light was irradiated on the inclined cover plate and worked continuously for 4 hours, and there was no obvious fog on the glass wall of the collector. The yield of desalinated seawater is 1.15kg / m 2 / h, the ion concentration of the produced fresh water meets the WHO drinking water standard, and the light-to-heat conversion efficiency reaches 78%.

Abstract

The invention discloses a solar water purifier based on interface solar photothermal conversion, which comprises a solar interface evaporator and a distilled water collector. body; the light absorbing body is a double-layer structure, which is composed of an upper layer of light-to-heat conversion material and a lower layer of heat insulating material, and a dust-free cloth is arranged between the upper layer and the lower layer of material; it is necessary to ensure that the dust-free cloth can continuously contact the storage The liquid level in the water tray to ensure that there is enough water transported to the absorber surface to ensure continuous evaporation. The invention only uses solar energy as the driving energy, does not need to consume other energy sources, and at the same time avoids the problem of replacing the filter element of the conventional water purifier. Sewage treatment and outdoor drinking water purification.

Description

technical field [0001] The invention belongs to the technical field of solar photothermal utilization and water purification, in particular to a solar water purifier based on interface solar photothermal conversion. Background technique [0002] With the rapid development of economy and society and the increasing environmental pollution, human beings have an increasing demand for clean water resources. At present, the water purification products on the market mainly use filtration to separate and obtain pure water. The filtration membranes are mainly divided into: ion exchange membrane, RO reverse osmosis membrane and ultrafiltration membrane. The filter element with the filter membrane as the core usually needs to be replaced after a period of use (3-24 months). The water purifier with this filtering method not only has high price of filter element consumables, but also requires external electric power to assist work. Therefore, a green and environmentally friendly water ...
