Embodiment Construction

[0012] A composite ceramic filter element is made of the following raw materials in parts by weight (kg):

[0013] Diatomaceous earth 14, activated carbon 38, carbon nanotube 2, silver nitrate 2, cocoic acid monoethanolamide 5, sodium metasilicate 7, propylene glycol 10, starch 5, ammonium bicarbonate 4, modified bentonite 20, water as appropriate.

[0014] Described modified bentonite is made by following method:

[0015] Calcinate bentonite at 520-540°C for 3-4 hours, take it out, cool it, soak it in 10-12% hydrochloric acid solution for 2-3 hours, then soak it in 10-12% sodium hydroxide solution for 1-2 hours , take it out, wash it with pure water, dry it and grind it into powder; then add aluminum nitride equivalent to 40% of the weight of bentonite, 18% of apocynum powder, 3% of alum powder, 3% of zeolite powder, 4% of brown sugar powder, mix and stir for 30-40 minutes, and then spray 7% bentonite weight Cross-linking agent TAC , Stir at 12000-15000 rpm ...

Abstract

The invention provides a composite ceramic filter core and a preparation method thereof. The composite ceramic filter core is prepared from 12 to 14 parts of diatomite, 36 to 38 parts of active carbon, 2 to 3 parts of a carbon nanotube, 1 to 2 parts of silver nitrate, 4 to 5 parts of coconut oil monoethanolamide, 7 to 9 parts of sodium metasilicate, 8 to 10 parts of propylene glycol, 3 to 5 parts of starch, 3 to 4 parts of ammonium bicarbonate, 20 to 25 parts of modified bentonite and a proper amount of water. The carbon nanotube used in the invention can improve mechanical properties of the ceramic filter core; meanwhile, the multiwalled carbon nanotube has a mesoporous structure and can effectively absorb and remove heavy metal ions in water. The composite ceramic filter core provided by the invention can be used for air filtration of an air-conditioning system, water filtration and inhalation filtration of an automobile filter and is applicable to a variety of places with a severe environment.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to a composite ceramic filter element and a preparation method thereof. Background technique [0002] Filter materials are widely used in chemical industry, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries; the most common ones are automotive air filters, which are used to filter the air entering the engine, and remove particulates and particles in the air. Mechanical impurity components are blocked, preventing these components from entering gasoline, diesel or engine oil, and ensuring the normal operation of the engine. There are also a large number of filter materials used in air conditioning systems. Now the environmental air pollution is very serious, which greatly endangers human health. Air filter materials can absorb various harmful particles in the air, prevent them from entering people's living or working environments, a...
