Abstract

The invention discloses a ceramic filter element added with carbon nano tubes. The ceramic filter element added with the carbon nano tubes is characterized by being prepared from the following raw materials in parts by weight: 15-17 parts of activated carbon, 10-13 parts of diatomite, 6-9 parts of cordierite, 2-3 parts of carbon nano tube, 3-5 parts of smashed cotton exocarp, 6-8 parts of smashed coconut shell, 7-9 parts of mica powder, 5-8 parts of clay, 8-10 parts of aluminium powder, 4-6 parts of zeolite, 1-2 parts of chitosan, 5-7 parts of modified coconut shell activated carbon and a defined amount of water. The ceramic filter element added with the carbon nano tubes is added with chitosan, so that the ceramic filter element added with the carbon nano tubes has good clarification and flocculation effects; the carbon nano tubes are added, so that the mechanical properties of the ceramic filter element can be improved; a mesoporous structure is formed, so that heavy metal ions in water can be effectively adsorbed and removed; modified coconut shell activated carbon is added, so that interspace is developed, the adsorption property is good, the strength is high, and the ceramic filter element added with the carbon nano tubes can be regenerated easily and is economical and durable; the purification efficiency is high, the service life is long, and the corrosion resistance is high, so that the ceramic filter element added with the carbon nano tubes can be used for air adsorption filtration or inspiration filtration by virtue of a car filter cleaner.

Description

technical field [0001] The invention relates to a filter material and a preparation method thereof, in particular to a ceramic filter element added with carbon nanotubes and a preparation method thereof. Background technique [0002] Filter materials are widely used, mainly used in coatings, inks, dyes, plastics, pharmaceuticals, electroplating, beverages, cosmetics, rubber, printing, electronic tube production, circuit board production, waste incineration, chemical production and other fields. The most common filter material is used in the air conditioning system. Now the air pollution in the environment is very serious, and the smog weather has brought great harm to people. The air adsorption filter material can absorb various harmful particles in the air, such as PM2.5 , prevent entering people's living or working environment, reduce the inhalation of harmful substances such as particulate matter in the human lungs, improve people's quality of life, and reduce the occurre...
