Self-adsorption air purification porous framework, preparation method and purification device

Abstract

The invention discloses a self-adsorption air purification porous framework, a preparation method and a purification device. The preparation method comprises the following steps of: preparing wood dust grains and mixing the wood dust grains with nano TiO2 powder, nano carbon powder and table salt grains; uniformly mixing the materials in a ball grinding mill; adding a silica sol binder and sufficiently agitating and mixing to prepare slurry; injecting the slurry into a mould to prepare a blank with the needed size; dissolving table salt out of the blank in water; drying the blank without the salt in a drying furnace at 100-150 DEG C; sintering the blank without the salt in a vacuum furnace at 300-400 DEG C; and preparing the porous framework. All parts are assembled to obtain the final product. Researches show that the porous framework obtained by the preparation method disclosed by the invention has a special space network topology structure; the framework has high porosity and relatively high compressive strength. The device disclosed by the invention can be used for purifying indoor air or discharging perfume or an aromatic into air.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a carbon-based composite material skeleton with a porous network structure for air purification based on the self-adsorption principle, a preparation method and a purification device. Background technique [0002] The main sources of indoor air pollution are: (1) Pollutants released by decoration materials; (2) Pollutants released by household appliances; (3) Air quality degradation caused by using air conditioners in relatively closed conditions; (4) Cooking oil heating Pollution gases and particles released indoors. As we all know, the most serious of the above pollution sources is the air pollution caused by decoration. After the house is decorated, harmful gases will be emitted indoors, such as formaldehyde, benzene, ammonia, etc. These harmful gases will affect the human respiratory system, cardiovascular system and nervous system. The system produces obvious adver...

Among these three methods, source control is the fundamental method to cure the root cause, and ventilation and dilution are also commonly used natural methods. However, when the above two methods are difficult to adopt, air purification is also an indispensable remedy.
