Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods, but it does not limit the present invention.

[0020] With reference to the accompanying drawings, the present invention is a water evaporation device that uses a lens to concentrate light, which mainly includes the following parts: a light collecting device, an evaporation condensation cover, an evaporation water collecting device, an evaporation generating device, a drainage rod and a water outlet.

[0021] The specific implementation is as follows:

[0022] (1) Before use, take out the evaporative condensing cover and the evaporative water collection device, spread them flat, and fill the middle layer with air. The parts are then assembled.

[0023] (2) Place the assembled evaporation device in the water source to be treated. Because the device is a hollow device, it will float on the water surface under the effect of buoyancy.

Abstract

The invention provides a simple and portable device for rapidly preparing purified water by utilizing solar energy, and belongs to the technical field of water evaporation. The device is mainly composed of a condensing lens, an evaporation and condensation cover, a water collecting device and a hydrothermal evaporation device. The steam condensation cover and the evaporated water collecting deviceare designed to be of a double-layer structure with a middle layer, the size of the device can be reduced after air is exhausted, and the device is convenient to carry. The device floats on the watersurface under the action of buoyancy, and water is absorbed to the photo-thermal conversion layer by capillary water absorption strips with high water absorption; the photo-thermal conversion layer is made of a dark-color and high-temperature-resistant light absorption material; the condensing lens is a convex lens and can condense a light source in the photo-thermal conversion process and then irradiate the photo-thermal conversion layer. The condensing lens can achieve efficient utilization of light, and then the photo-thermal conversion efficiency is improved. The vaporized water is liquefied on the inner wall of the condensation cover under the action of high temperature and then collected. Therefore, sewage purification, seawater desalination and other applications are realized.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a simple and portable device for rapidly preparing purified water by utilizing solar energy. Background technique [0002] By using water evaporation, the reuse of waste water and seawater desalination can be realized. Thereby alleviating the current shortage of fresh water resources in the world. [0003] The traditional solar water evaporation device vaporizes liquid water through direct sunlight, but due to the poor light absorption ability of water, and the large volume of water targeted by this method, the heat dissipation is fast, so the utilization rate of sunlight is low . In order to improve the utilization rate of sunlight, increase the evaporation rate. In recent years, a large number of researchers have devoted themselves to the study of photothermal conversion materials. Photothermal conversion materials are of course important for improving light utiliza...
