Multifunctional air purifier with functions of oxygen supplement and carbon dioxide absorption and oxygen supplement and carbon dioxide absorption method

Abstract

A multifunctional air purifier with functions of oxygen supplement and carbon dioxide comprises six function modules. The air purification module is used for killing bacteria and viruses and degrading various pollutants such as formaldehyde and benzene by high-energy positive oxygen ions generated by an ionization tube; high-energy negative oxygen ions can clear various suspended particles in air, such as PM2.5. The chemical oxygen production module supplements oxygen by using calcium peroxide and the like as oxygen producing agent. The CO2 absorption and PM2.5 removal module is capable of removing inorganic pollutants such as carbon dioxide and various suspended particles in air, including PM2.5, by calcium hydroxide and water in oxygen production waste liquid. The vehicular power module provides three USB interfaces and a standard power interface (+5V / 500mA). The harmful gas alarm module has the function of warning on over-standard density of carbon monoxide, methylbenzene, ammonia and the like. The electronic control module is used for controlling ordered operation of a whole system.

Description

Technical field [0001] The present invention relates to a kind of air purifier, relate in particular to a kind of oxygen (O 2 ), absorbing carbon dioxide (CO 2 )'s multifunctional air purifier consists of six functional modules. Among them: the air purification module uses the high-energy positive oxygen ions generated by the ionization tube to kill bacteria and viruses, degrades various pollutants such as formaldehyde and benzene, and the high-energy negative oxygen ions to remove suspended particles including PM2.5; the chemical oxygen production module uses calcium peroxide etc. as an oxygen generator to supplement oxygen; CO 2 The absorption / PM2.5 removal module uses calcium hydroxide and water in the oxygen waste liquid to remove inorganic pollutants such as carbon dioxide and various suspended particles in the air including PM2.5; the vehicle power supply module provides three USB interface standard power sockets ( +5V / 500mA); the harmful gas alarm module provides ala...

AI Technical Summary

Problems solved by technology

[0005] (1) Oxygen-generating equipment is not installed, and there is nothing that can be done to reduce the oxygen content of the air in the confined space;

[0006] (2) For carbon dioxide (CO 2 ) has no purification ability, while CO in the air 2 Elevated levels can cause symptoms such as headache, nausea, and dyspnea;

[0007] (3) Air purifiers based on room temperature catalytic oxidation technology and photocatalytic technology mostly use a variety of nanomaterials, and during production and use, if nanoscale material particles enter the human body, they will be harmful to humans;

[0008] (4) Various types of air purifiers mostly use various filters such as HEPA filters and activated carbon, and filters and activated carbon are consumables that need to be replaced frequently, which makes the operation and maintenance costs of the air purifier a heavy burden for users economic burden;

[0009] (5) Some air purifiers need to use ultraviolet light and ozone to purify the air, and if the ultraviolet light leaks or the ozone concentration exceeds the standard, it will cause serious harm to the human body, and it is very difficult to accurately control the ozone concentration

The reason is that people cannot smell the most dangerous CO, and the current car and car air purifiers generally do not have the function of detecting and alarming the carbon monoxide and nitrogen oxides that the occupants of the car most need to prevent in the exhaust gas.
