Material for catalytically decomposing formaldehyde and ammonia gas and formaldehyde removal and deodorization purifier prepared from material

Abstract

The invention discloses a material for catalytically decomposing formaldehyde and ammonia gas and a formaldehyde removal and deodorization purifier prepared from the material. The purifier comprises apurifier carrier and a formaldehyde and ammonia gas catalytic decomposition material arranged in the carrier, and the formaldehyde and ammonia gas catalytic decomposition material is prepared from the following raw materials: high-porosity manganese oxide fiber microspheres, an adhesive, clay, deionized water and functional powder for removing formaldehyde; the preparation method of the high-void-ratio manganese oxide fiber microspheres comprises the following steps: twisting and gathering manganese oxide fiber membranes with the width of 1.5 m and disorderly distributed internal fibers to form manganese oxide fiber bundles, cutting off, and extruding to form nano fiber microspheres with a porous structure, thereby providing more active sites for catalytic decomposition of formaldehyde; according to the prepared catalytic decomposition agent, manganese oxide serves as a carrier, manganese oxide is loaded, the formaldehyde decomposition effect is improved, rapid adsorption and decomposition of formaldehyde molecules can be achieved under the condition that energy such as photoelectricity is not needed, the purification efficiency is high, the effect is good and secondary pollutionis avoided.

Description

technical field [0001] The invention relates to the technical field of formaldehyde removal materials and equipment, in particular to a formaldehyde removal and deodorization purifier prepared by catalytically decomposing formaldehyde and ammonia gas materials and the same. Background technique [0002] The existing indoor formaldehyde removal methods mainly include activated carbon method, photocatalyst method and precious metal catalyst method. The activated carbon method can adsorb harmful substances. The duration of activated carbon is three to six months, and then it will be saturated and lose its activity. However, when the environmental conditions change, such as temperature rises, air pressure changes, etc., the adsorbed formaldehyde may be released again, causing secondary pollution. secondary pollution. The adsorption saturation of the activated carbon method is fast, and the activated carbon needs to be replaced frequently. The photocatalyst is the sharp mineral...

AI Technical Summary

Problems solved by technology

Noble metal catalysts for removing formaldehyde have good effect and slow deactivation, but many noble metal catalysts need to be heated to exert their effect. There are few noble metal catalysts for removing formaldehyde at room temperature on the market, and most of the noble metal catalysts are made of nano-scale platinum, which is expensive and common Families are unbearable, therefore, need a kind of catalytic decomposition formaldehyde ammonia gas material and its preparation formaldehyde deodorization purifier
