Embodiment Construction

[0011] A filter element for filtering harmful gases, made of the following raw materials in parts by weight (kg):

[0012] Polyethylene powder 4, bamboo charcoal powder 20, sepiolite powder 12, diatomite 6, sodium carbonate 1, soybean oil 6, starch 2, sodium dodecylbenzene sulfonate 2, clay 30, modified attapulgite 12, Appropriate amount of water.

[0013] Described modified attapulgite is made by following method:

[0014] Calcinate attapulgite at 450-500°C for 3-4 hours, take it out, cool it, soak it in 10-12% hydrochloric acid solution for 1-2 hours, take it out, wash it with pure water, dry it and grind it into powder; Add aluminum nitride equivalent to 40% of the weight of attapulgite, 23% of Gynostemma powder, 3% of aluminum hydroxide, 3% of zirconium fluoride, 3% of graphite, 4% of sodium bicarbonate, mix and stir for 30- After 40 minutes, spray silane coupling agent KH550 equivalent to 15% of the weight of attapulgite, and stir at 12000-15000 rpm for 60-80 minute...

Abstract

The invention discloses a filter core used for filtering harmful gas and a preparation method thereof. The filter core comprises following raw materials, by weight, 2 to 4 portions of polyethylene powder, 18 to 20 portions of bamboo charcoal powder, 12 to 14 portions of meerschaum powder, 4 to 6 portions of diatomite, 1 to 2 portions of sodium carbonate, 4 to 6 portions of soybean oil, 2 to 3 portions of starch, 1 to 2 portions of sodium dodecyl benzene sulfonate, 30 to 35 portions of white clay, 10 to 12 portions of modified attapulgite and an appropriate amount of water. The filter core is high in purification efficiency, less in pressure loss, and long in service life; is resistant to high temperature and corrosion; is capable of removing micro dust in the air; can be used for air filtration of air conditioning systems, water filtration, and suction filtration of vehicle filter cleaners; and is suitable for places with poor environmental conditions.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to a filter element for filtering harmful gases 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 enviro...
