Abstract

The invention discloses a porous ceramic catalytic oxidizer, a preparation method thereof and a multipurpose efficient air purification device and belongs to the technical field of environments. A columnar ceramic pillar in the porous ceramic catalytic oxidizer takes diatomite as a main material, Fe-Cr-Al alloy wires are taken as support and internal heating wires, cotton and silk are taken as printing templates, a blank is prepared with a compression molding method, the Fe-Cr-Al alloy wires for support are powered on to assist in heating, and calcination in a high-temperature furnace is performed, and the porous ceramic catalytic oxidizer is prepared. The multipurpose efficient air purification device comprises the porous ceramic catalytic oxidizer, a catalytic oxidation electrode, a capturing catalytic oxidation net, a fan and a supply and regeneration device, the porous ceramic pillar of a special structure is supplied with an oxidizer by means of a concentric tube oxidizer supply technology and device, and cooperative treatment of chemical catalytic oxidation and electrocatalytic oxidation of harmful gas is realized in combination with the catalytic oxidation electrode and thecapturing catalytic oxidation net arranged behind the columnar ceramic pillar. The multipurpose efficient air purification device can realize efficient oxidation purification of multiple substances inair and waste gas and has higher economic and environmental benefits.

Description

technical field [0001] The invention belongs to the field of environmental technology, and relates to a porous ceramic catalytic oxidizer, a preparation method thereof, and a multipurpose high-efficiency air purification device. Background technique [0002] Air is the basis for human survival. Whether it is indoor air or outdoor air, its pollution will seriously affect people's survival and health. The main pollutants in indoor air are formaldehyde, benzene, toluene, TVOC, ammonia, carbon monoxide, ozone, benzo[a]pyrene B(a)P, PM2.5 and viral microorganisms. Outdoor air pollutants mainly include sulfur dioxide, nitrogen dioxide, ozone, particulate matter (including TSP, PM2.5 and PM10), etc. These pollutants mainly come from direct emissions from industrial production, daily life, fossil fuel combustion, etc., and The pollutants are regenerated after reacting in the atmosphere. [0003] At present, the commonly used methods in the field of indoor air purification are: mec...
