AI Technical Summary

Problems solved by technology

These methods are often cumbersome or not efficient enough or cost too much or have other side effects
For example, spraying peracetic acid against SARS virus is troublesome to spray on a large area, and peracetic acid decomposes quickly and it is difficult to maintain the effect for a long time. Spraying too much smells bad, and even some people have allergic reactions

Embodiment 1

[0016] in an area of ​​15m 2 , in a closed room with a floor height of 3m, the air volume is about 45m 3 , put a 50W fan. Under normal circumstances, the air volume of this fan is about 18m 3 / minute. Put a piece of multi-layer glass fiber (total thickness is about 1mm) on the air inlet with about 1% weight of potassium permanganate and 0.1% sulfuric acid adhered on it with aluminum sol; filter material clamped by polyethylene mesh on both sides , when the fan is turned on, due to the increased resistance, the air volume is reduced by about 3 / 4, and the air circulation volume is about 4.5m 3 , about 45m in 10 minutes 3 The air (equivalent to the volume of the room) passes through the filter material, and the volume of air circulating through the fan per hour is about six times the volume of the room. After the fan is turned on for four hours, most of the dust, bacteria and viruses in the room can be removed.

Embodiment 2

[0018] In a room with an area of ​​20m 2 , in a room with a floor height of about 2.6m, the air volume is about 52m 3 , install a detached air conditioner, install a piece of filter material similar to Example 1 on the return air outlet of the air conditioner, and most of the dust, bacteria and viruses in the room can be removed after the air conditioner is started for four hours.

Abstract

The invention provides a kind of air filtering and purifying material and the using method. It is made up of strong oxidizer and non-volatile acid or alkalis which are attached on spongy ventilate carrier material that is oxytolerant acid proof. The method is: puts the material at the entrance or outlet of ventilate pipe in fan or conditioner. The invention uses the strong oxidisability of the strong oxidizer and acid or alkali environment to sterilize virus or bacteria, and eliminate the organic contamination and harmful material such as amine. It can be used in air sterilization and purification of hospital, home, hotal, office building, meeting room, train, plane, ship and so on.

Description

Technical field: [0001] The invention belongs to the technical field of air purification materials, and in particular relates to an air filtration purification material capable of killing viruses and bacteria in the air and removing pollutant molecules. Background technique: [0002] Air disinfection and purification are of great importance to human health. The air often contains organic or inorganic substances harmful to human health such as viruses, bacteria or other pathogens, as well as formaldehyde, organic solvents and ammonia. Viruses and bacteria in the air are often killed by spraying peracetic acid, chlorine dioxide, or boiling vinegar, Chinese herbal medicine, or using ozone, or using ultraviolet radiation, and also commonly used methods such as activated carbon adsorption for air purification. These methods are often cumbersome or not efficient enough or cost too much or have other side effects. For example, spraying peracetic acid against SARS virus is trouble...
