Device for performing sewage purification by utilizing solar energy based on photo-thermal conversion material

Abstract

The invention discloses a device for performing sewage purification by utilizing solar energy based on a photo-thermal conversion material. The device comprises a water collecting tank which is used for collecting condensed clean water; the upper end of a filtering container is provided with an opening serving as a water inlet, the lower end of the filtering container is sealed, and a filtering layer of the filtering container is arranged at the middle part of the filtering container; a water absorption material is inserted into a thermal insulation foam material, water is guided into the photo-thermal conversion material through capillary action, and the photo-thermal conversion material is horizontally placed on the upper surface of the thermal insulation foam material; an external quartz container and an internal container are communicated with the filtering container through a two-way guide pipe; the top of the external quartz container is conical; the internal water absorption material, the thermal insulation foam material and the photo-thermal conversion material are fixed in the internal container; the upper end of the internal container is opened, and the lower end of the internal container is sealed; and the internal container is fixed at the bottom of the external quartz container. By combination of filtration and a solar water evaporation technology, the device can realize treatment on various types of sewage.

Description

technical field [0001] The invention relates to the technical field of application of functional materials, in particular to a device for purifying sewage by utilizing solar energy based on photothermal conversion materials. Background technique [0002] With the development of the economy and the growth of the population, the pollution of the water body has been exacerbated, resulting in a serious shortage of water resources. Sewage includes industrial wastewater, domestic sewage, commercial sewage and surface runoff. Due to its complex composition and various types of pollutants, such as particulate matter, heavy metals, toxic organic substances, bacteria, pathogens, etc., it is difficult to achieve efficient sewage purification to obtain clean water. [0003] Solar energy is a green, clean, and renewable energy source. Based on photothermal conversion materials, the absorbed solar energy is effectively converted into thermal energy, which further heats water and collects ...
