Problems solved by technology

[0003] In recent years, air purification nets have been widely recognized and applied by people. The filter system mainly uses non-woven fabric or paper to filter particle dust, activated carbon to absorb harmful odors, etc. This method is theoretically effective, but due to the physical characteristics of these materials The decision has obvious defects, such as once activated carbon is combined with water molecules in the air, it loses the ability to effectively adsorb, so the use time is short and the capacity is poor.

Embodiment 1

[0022] Example 1 Preparation of far-infrared adsorption particles

[0023] The far-infrared adsorption particles are prepared by the following method:

[0024] 1) Use a roasting furnace to heat graphite to 500-1000°C, and generate graphite "worms" after heating and expansion; the outer wall of "worms" has holes, and these holes are interconnected to form a network void structure, which greatly increases the adsorption of harmful gases;

[0025] 2) Use a roaster to heat tourmaline tourmaline to 500-1000°C to remove impurities and purify it;

[0026] 3 ) Using the surfactant alkanolamide, mix the expanded graphite obtained in step 1) with the tourmaline tourmaline obtained in step 2) in a mass ratio of 1:1 under ultrasonic conditions, add ammonium acetate metal salt solution, and continue ultrasonication , mixed into a uniform far-infrared adsorption liquid;

[0027] 4) Transfer the far-infrared adsorption liquid in step 3) into an autoclave, raise the tem...

Embodiment 2

[0029] Embodiment 2 Preparation of air purification filter screen

[0030] 1) Preparation of activated carbon: Use dry high-quality coconut shells, use an internal heating high-temperature rotary furnace and pass in water vapor for activation, keep the temperature at 400-600°C, and make activated carbon particles with black blocky appearance and cool to room temperature.

[0031] 2) Preparation of the filter screen: Use paper, plastic or aluminum materials to make a honeycomb filter screen support, and adhere a breathable and leak-proof high-density mesh material on one side; use the coconut shell activated carbon particles obtained in step 1) Microwaves are directly heated to 100-150°C, and after drying, the far-infrared adsorption particles obtained in Example 1 are evenly distributed in the honeycomb support in a ratio of 1:10; Net stand.

Embodiment 3

[0032] Example 3 Preparation of air purification filter

[0033] Use papery, plastics or aluminum material to make honeycomb filter screen support, and adhering ventilative and leak-proof high-density mesh material on one side, then evenly put in embodiment 1 gained far-infrared adsorption particles and The coconut shell activated carbon granule of embodiment 2 gained, finally use the air-permeable leakage-proof high-density mesh material to block the filter screen support after feeding.

Abstract

The invention relates to an air purification filter screen. The air purification filter screen comprises a rectangle frame, a filter screen support, a filter material and upper and lower-layer protecting nets, wherein the filter screen support and the filter material are arranged between the upper and lower-layer protecting nets; the air purification filter screen is characterized in that effective active substances of the filter material comprises active carbon granules and far infrared adsorbing granules, and the mass ratio of expanded graphite to tourmaline in the far infrared adsorbing granules is 1 to 1. The air purification filter screen provided by the invention has the advantages that far infrared rays can be continuously released, the effective acting time of activated carbon in the filter material is prolonged, and the eliminating role on natural bacteria in the air can be realized.

Description

technical field [0001] The invention relates to a filter net, in particular to an air purification filter net. Background technique [0002] With the rapid development of industrial production, the urban environment is increasingly polluted from all aspects, and the bodies of residents living in the city are affected by air pollution. Due to the decline in outdoor air quality, it also affects the quality level of air in the city. Research and development A filter system that efficiently and quickly filters dust in the air and reduces and kills pathogenic microorganisms in the air will play a positive role in human health. [0003] In recent years, air purification nets have been widely recognized and applied by people. The filter system mainly uses non-woven fabric or paper to filter particle dust, activated carbon to absorb harmful odors, etc. This method is theoretically effective, but due to the physical characteristics of these materials Determination has obvious defec...
