Air purification device based on biomass protein graphene nano composite material

Abstract

The invention relates to a device in the field of air purification, in particular to an air purification device based on a biomass protein graphene nano composite material. The device comprises a shell. A purification cavity, a gas inlet cavity and a multi-stage filter cavity are sequentially formed in the shell from bottom to top and are separated through perforated plates. A base is arranged at the bottom of the shell. A purified gas outlet structure is arranged at the top of the shell and communicated with the multi-stage filter cavity. Graphene aerogel net columns are detachably arranged in the purification cavity, a circulating water cavity is formed outside the graphene aerogel net columns, a water inlet is formed in the lower portion of the circulating water cavity, and a water outlet is formed in the upper portion of the circulating water cavity. The three-dimensional macroporous graphene aerogel placed in the graphene aerogel net column is used for adsorbing impurities in air, and the air is adsorbed, circularly washed and purified in cooperation with circulating water washing.

Description

technical field [0001] The invention relates to a device in the field of air purification, in particular to an air purification device based on a biomass protein-based graphene nanocomposite material. Background technique [0002] Airgel is composed of the solid part of the gel plus air, which itself is solid, and because the airgel is mainly air, it is much heavier than air. The three-dimensional structure of the multi-level porous graphene airgel is Using biomass protein as a template, graphene and other materials are formed into a graphene nanocomposite material with a certain spatial structure by introducing heteroatoms and self-assembly. At present, there is little research on the application of this composite material in the field of air purification. Contents of the invention [0003] In order to solve the problems in the prior art, the present invention discloses an air purification device based on a biomass protein-based graphene nanocomposite material.

Problems solved by technology

[0002]Aerogels are composed of the solid portion of the gel plus air, are themselves solids, and since aerogels are mostly air, they weigh significantly more than air , the three-dimensional structure of hierarchically porous graphene airgel is based on biomass protein as a template, and graphene and other materials are formed into a graphene nanocomposite material with a certain spatial structure by introducing heteroatoms and self-assembly. The synergistic effect between alkene and different materials is used to construct adsorption materials with higher performance. At present, there are few studies on the application of this composite material in the field of air purification.
