Abstract

The invention provides preparation equipment and a preparation process for photocatalytic ceramic spheres, relates to the field of photocatalytic ceramic sphere devices, and aims to prepare photocatalytic ceramic spheres and externally apply titanium dioxide (TiO2) to the spheres because the titanium dioxide (TiO2) is a photocatalyst, is high in photochemical stability, can mineralize organic pollutants and is free of secondary pollution. Because the photocatalysis technology has obvious effects in the field of water purification, especially wastewater treatment, is used for treating industrial sewage and urban domestic sewage and treating and inhibiting blue algae from decomposing cyanobacteria toxins, the characteristic that photocatalysis ceramic spheres can be used for stopping catalysis in natural light is fully utilized, and the surface of a photocatalysis reactor is made of a transparent material; natural light is fully utilized for photochemical reaction, the ceramic pellet loaded titanium dioxide photocatalyst produced by a mechanical film forming method (MCT) overcomes the defect that powder nano titanium dioxide is difficult to separate from a water body, the purification process is reliable, and centrifugal separation of the powder nano titanium dioxide is not needed.

Description

technical field [0001] The invention relates to the technical field of photocatalytic ceramic spheres, in particular to equipment and a preparation process for photocatalytic ceramic spheres. Background technique [0002] In the design and manufacture of water treatment equipment, make full use of the characteristics of photocatalytic ceramic balls that can be photocatalyzed in natural light, and use transparent materials on the surface of the photocatalytic reactor to make full use of natural light. It reflects that the interior can be designed and installed with an ultraviolet light source, which can play a role in that the catalytic efficiency of ultraviolet light is higher and the natural light condition is not good. [0003] The existing preparation methods of ceramic pellets mainly include mechanical method, granulation-rolling method, extrusion molding-rolling method, mold pressing method, melting method and sol-gel method, etc. In the process of preparing ceramic pe...
