Embodiment Construction

[0012] An activated carbon fiber filter element is made of the following raw materials in parts by weight (kg):

[0013] Sodium petroleum sulfonate 3, activated carbon fiber 14, clay 10, clay 12, silver nitrate 2, polyvinyl alcohol 5, dimolybdenum boride 3, ammonium molybdate 1, zinc powder 2, iron powder 2, brown sugar 4, calcium carbonate powder 7. Modified bentonite 15. Appropriate amount of water.

[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 brown sugar, 3% of zeolite powder, and 4% of carbonized Tungsten powder, mixed and stirred for 30-40 minutes, and then spray...

Abstract

The invention provides an active carbon fiber filter core and a preparation method thereof, and is characterized in that: the filter core is prepared from the following raw materials, in parts by weight: 3-4 parts of sodium petroleum sulfonate, 12-14 parts of active carbon fibers, 8-10 parts of clay, 12-14 parts of hargil, 1-2 parts of silver nitrate, 5-7 parts of polyvinyl alcohol, 2-3 parts of molybdenum boride, 1-2 parts of ammonium molybdate, 1-2 parts of a zinc powder, 1-2 parts of an iron powder, 4-6 parts of brown sugar, 5-7 parts of a calcium carbonate powder, 10-15 parts of modified bentonite, and a proper amount of water. Silver nitrate has a bactericidal effect, and at the same time, active carbon has better effect of adsorption of impurity microparticles; and the filter core has high strength, is not easy to damage, has the outstanding advantages of high purification efficiency, high temperature resistance, low pressure loss, corrosion resistance, and long service life, and can also remove micro-dust in air.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to an activated carbon fiber filter core 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...
