Embodiment 1

[0026] (1) Under laboratory conditions, formaldehyde, benzene, toluene, xylene, and TVOC generators are used to generate harmful gases in a confined space, and the concentration of formaldehyde in the indoor air used for the adjustment experiment is 0.15 mg / m 3 , Benzene concentration is 0.2 mg / m 3 , toluene concentration is 0.2 mg / m 3 , The concentration of xylene is 0.2 mg / m 3 , TVOC concentration is 0.6 mg / m 3 . (2) The diameter of activated carbon particles used in the experiment is 3mm, and the total mass of activated carbon is 500g. The air first enters the device from the air inlet of the device, and the activated carbon inside the device can fully contact with the air, and the harmful components in the air are absorbed by the activated carbon. (3) The gas treated by the equipment of the present invention is discharged from the gas outlet. After testing, the formaldehyde concentration of the outlet gas is 0.01 mg / m 3 , Benzene concentration is 0.01 mg / m 3 , toluen...

Embodiment 2

[0028] (1) The formaldehyde concentration in the indoor air used in the experiment is adjusted to 0.12 mg / m by a gas generator 3 , Benzene concentration is 0.2mg / m 3 , toluene concentration is 0.15 mg / m 3 , The concentration of xylene is 0.15 mg / m 3 , TVOC concentration is 0.5 mg / m 3 . (2) The diameter of activated carbon particles used in the experiment is 3mm, and the total mass of activated carbon is 500g. The air first enters the interior of the equipment from the air inlet of the equipment of the present invention, the activated carbon inside the equipment can fully contact with the air, and the harmful components in the air are absorbed by the activated carbon. (3) The gas treated by the equipment of the present invention is discharged from the gas outlet. After testing, the formaldehyde concentration of the outlet gas is 0.01 mg / m 3 , Benzene concentration is 0.02 mg / m 3 , toluene concentration is 0.01 mg / m 3 , The concentration of xylene is 0.01 mg / m3 , TVOC con...

Embodiment 3

[0030] (1) The formaldehyde concentration in the indoor air used in the experiment is adjusted to 0.12 mg / m by a gas generator 3 , Benzene concentration is 0.2mg / m 3 , toluene concentration is 0.3 mg / m 3 , The concentration of xylene is 0.3 mg / m 3 , TVOC concentration is 1.5 mg / m 3 . (2) The diameter of activated carbon particles used in the experiment is 3mm, and the total mass of activated carbon is 500g. The air first enters the interior of the equipment from the air inlet of the equipment of the present invention, the activated carbon inside the equipment can fully contact with the air, and the harmful components in the air are absorbed by the activated carbon. (3) The gas treated by the equipment of the present invention is discharged from the gas outlet. After testing, the formaldehyde concentration of the outlet gas is 0.01 mg / m 3 , Benzene concentration is 0.02 mg / m 3 , toluene concentration is 0.03 mg / m 3 , The concentration of xylene is 0.03 mg / m 3 , TVOC con...

Abstract

The invention discloses vehicle-mounted air purification equipment without replacement of a filter element. A dust removal filter screen, an on-off sealing valve I, an activated carbon filter layer and an induced draft fan are sequentially arranged inside the equipment; the on-off sealing valve I and the on-off sealing valve II are turned on; and multiple activated carbon heating wires are arranged inside the activated carbon filter layer, a vacuum pump is arranged above the activated carbon filter layer, and the vacuum pump is also connected with an exhaust emission pipe. The vehicle-mounted air purification equipment disclosed by the invention has an activated carbon regenerating function, and activated carbon regeneration treatment can be carried out when activated carbon in the equipment is saturated in adsorption, so that the problems of physical adsorption saturation, secondary pollution, high usage cost and the like are avoided, and the activated carbon can be used for a long time. After treatment by virtue of the vehicle-mounted air purification equipment disclosed by the invention, content of formaldehyde, benzene, methylbenzene, dimethylbenzene, TVOC and the like in the air in a vehicle is obviously lowered, the vehicle-mounted air purification equipment disclosed by the invention is high in purification efficiency and can continuously operate for a long time, the defects such as adsorption saturation and secondary pollution of other air purifiers are avoided, and the aim of purifying the air in the vehicle is achieved.

Description

technical field [0001] The invention relates to an air purification device, in particular to an air purification device for automobiles. Background technique [0002] With the improvement of people's living standards and the rapid development of the automobile industry, automobiles have become an indispensable means of transportation in people's daily life, and the air quality in the car has attracted more and more attention. However, a variety of reasons lead to poor air quality in the car, which is not suitable for human breathing. [0003] Due to the raw material problems of new car interiors and other items, the content of formaldehyde, benzene, toluene, xylene, TVOC, etc. in the air in the car often exceeds the standard. Excessive levels of these harmful gases often cause red eyes, itchy eyes, throat discomfort or pain, sound Hoarseness, sneezing, chest tightness, wheezing, dermatitis, etc. In addition, when the air conditioner in the car is turned on, the space insid...
