Problems solved by technology

[0002] At present, the pure natural purification products on the market are mainly activated carbon and bamboo charcoal, but these two types of products only have a simple physical adsorption function, and cannot remove harmful substances such as formaldehyde and benzene. Sorption saturation occurs and even possible re-release under certain conditions

Abstract

The invention belongs to the technical field of environmental protection materials and relates to multi-functional photocatalyst diatom purification particles and a preparation method thereof. The preparation method includes the following steps of: uniformly stirring 50-70 parts of diatomite, 5-15 parts of attapulgite, 10-20 parts of zeolite powder, 5-10 parts of sepiolite, 5-8 parts of negative ion powder, 3-5 parts of far infrared ceramic powder, 20-30 parts of kaolin, 5-15 parts of nano-photocatalysts and proper deionized water, and then pelletizing the mixture; perform primary drying on pellets in a low-temperature drying furnace for 3-4 hours at a drying temperature of 100-300 DEG C; and activating the pellets in a high-temperature activating oven at a constant activation temperature of 550-650 DEG C for 2 hours. The prepared multi-functional photocatalyst diatom purification particles have higher porosity than activated carbon, and can decompose harmful substances such as formaldehyde, overcome the technical disadvantage that the activated carbon and other products only can adsorb but cannot decompose harmful substances and release negative oxygen ions and far infrared rays beneficial to a human body.

Description

technical field [0001] The invention belongs to the technical field of environmental protection materials, relates to a photocatalyst multifunctional diatom purification granule, and also relates to a preparation method of the purification granule. Background technique [0002] At present, the pure natural purification products on the market are mainly activated carbon and bamboo charcoal, but these two types of products only have a simple physical adsorption function, and cannot remove harmful substances such as formaldehyde and benzene. Adsorption saturation occurs and even re-release is possible under certain conditions. [0003] Although photocatalyst composite activated carbon has also appeared on the market, since the porosity of diatomite is 5000-6000 times that of activated carbon, and the diatomite purified particles with diatomite as the main raw material are formed by enrichment pore-forming technology. The pore size is more conducive to the attachment and adsorp...
