Problems solved by technology

[0005] The physical ventilation method is to discharge harmful gases to the outside through the flow of air. This is a simple formaldehyde treatment method. The disadvantage is that the release cycle of formaldehyde and other toxic gases is long, which generally takes three to fifteen years. It is obviously unrealistic for a new car to be idle for more than three years
[0015] At present, the purification efficiency of the commonly used car air purifiers on the total volatile organic compounds in the car, especially the purification efficiency of formaldehyde, still needs to be improved

Embodiment 1

[0072] Use the above-mentioned car air purifier to purify the air in the five-seat new car whose formaldehyde and other VOCS gases exceed 4 times the national standard. The first filter screen 110 of the vehicle-mounted air cleaner includes a first mesh plate 112 and active potassium permanganate carried by the first mesh plate 112, the particle diameter of the active potassium permanganate is about 4mm, and the dosage It is 50g; The second filter screen 120 includes the second mesh plate and the activated alumina carried by the second mesh plate, the particle diameter of the activated alumina is about 4mm, and the consumption is 50g; the third filter The net 130 includes a third mesh plate and a 13X molecular sieve carried by the third mesh plate, the particle size of the 13X molecular sieve is about 4mm, and the dosage is 100g; the filter frame 12 is placed in the cavity for The plurality of filter screens 10 are carried, and the plurality of filter screens 10 are arranged o...

Embodiment 2

[0075] Use the above-mentioned vehicle-mounted air cleaner to purify the same indoor space as that of Embodiment 1; the difference between Embodiment 2 and the vehicle-mounted air cleaner of Embodiment 1 is that the second filter screen 120 is close to the air outlet 90, The third filter screen 130 is disposed between the first filter screen 110 and the second filter screen 120 .

[0076] Experiments have proved that it only takes 1.5 hours to purify the above-mentioned harmful gas exceeding the standard by 4 times in the car to be lower than the national standard.

Abstract

The invention provides a vehicle-mounted air purifier. The vehicle-mounted air purifier comprises a shell, a plurality of filter screens, a filter screen rack power supply unit and at least one fan; the shell comprises a first end cover, a side wall and a second end cover, and the first end cover, the side wall and the second end cover jointly form a cavity; the plurality of filter screens comprise a first filter screen, a second filter screen and a third filter screen; the first filter screen comprises a first screen plate and active potassium permanganate borne by the first screen plate; thesecond filter screen comprises a second screen plate and activated aluminum oxide borne by the second screen plate; the third filter screen comprises a third screen plate and a 13X molecular sieve carried by the third screen plate; the filter screen frame is arranged in the cavity and used for bearing a plurality of filter screens, and the plurality of filter screens are arranged on the filter screen frame in parallel; the power supply unit is arranged in the cavity, is positioned on the upper surface of the second end cover and is electrically connected with the fan; and at least one air outlet is formed in the first end cover, and at least one fan is arranged in a corresponding one of the at least one air outlet.

Description

technical field [0001] The invention belongs to the field of air purification, in particular to a vehicle-mounted air purifier. Background technique [0002] At present, raw materials containing total volatile organic compounds such as formaldehyde, ammonia, benzene, toluene, and xylene are widely used in the fields of decoration, furniture manufacturing, adhesive manufacturing, textile manufacturing, and automobile manufacturing. These volatile toxic gas pollutants are recognized by the World Health Organization as toxic substances that cause continuous damage to the human body. The main hazards are the stimulation and damage to the human respiratory system, nervous system, and skin and mucous membranes. Among them, formaldehyde has high reactivity, and can undergo nucleophilic addition reaction with molecules with hydroxyl, sulfhydryl, and amino groups, prevent the synthesis of nuclear proteins in the human body, and inhibit cell division and the synthesis of nucleus and c...
