AI Technical Summary

Technical Problem

Existing floating evaporators face problems such as reduced efficiency due to organic matter accumulation, biofilm formation hindering evaporation, and poor stability when treating high-concentration organic wastewater.

Method used

The photothermal evaporator, which employs a built-in buoyancy enhancer and a photocatalytic functional layer, achieves organic matter degradation and microbial inhibition through the synergistic effect of photothermal and photocatalysis, while ensuring the stable floating of the evaporator and avoiding accumulation.

Benefits of technology

While achieving efficient evaporation and concentration of brine, it simultaneously degrades organic pollutants, inhibits microbial growth, ensures long-term stable operation of the evaporator, and improves evaporation efficiency and stability.

Abstract

The utility model provides a kind of antibacterial anti-pollution floating type photo-thermal evaporator, and evaporator is by spherical or cylindrical core structure, the buoyancy enhancer being arranged in the inside of core structure and the photocatalytic function layer being loaded in the inner and outer surfaces of core structure constitute;Photocatalytic function layer is loaded in the porous structure of spherical or cylindrical sponge, sunlight simultaneously excites photo-thermal effect and photocatalytic effect, two processes are carried out on the same interface in cooperation, realizes the integrated processing of wastewater evaporation concentration and organic pollutant degradation.Photo-catalytic function layer continuously produces active oxygen species under solar irradiation, can efficiently kill the bacteria, algae and their spores attached to the surface of evaporator, prevent biofilm formation.Foam frame can limit the horizontal movement range of evaporator, prevent the accumulation of evaporator on water surface, maintain the high-flux evaporation efficiency of each evaporator.
