Embodiment 1

[0029] (1) Under laboratory conditions, formaldehyde, benzene, toluene, xylene, and TVOC generators are used to generate harmful gases in a closed room, and the indoor air used for the adjustment experiment has a formaldehyde concentration of 0.3 mg / m 3 , Benzene concentration is 0.3 mg / m 3 , toluene concentration is 0.4 mg / m 3 , The concentration of xylene is 0.4 mg / m 3 , TVOC concentration is 1 mg / m 3. (2) The diameter of activated carbon particles used in the experiment is 3mm, and the total mass of activated carbon is 4kg. The air first enters the interior of the equipment from the air inlet of the equipment of the present invention, and the activated carbon inside the equipment is arranged in a track shape, so that it 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 ...

Embodiment 2

[0031] (1) The formaldehyde concentration in the indoor air used in the experiment is adjusted to 0.4 mg / m by a gas generator 3 , Benzene concentration is 0.4mg / m 3 , toluene concentration is 0.4 mg / m 3 , The concentration of xylene is 0.4 mg / m 3 , TVOC concentration is 1 mg / m 3 .

Abstract

The invention discloses filter element replacement-free air purifying equipment which comprises a housing and a power supply as well as an air inlet switch seal valve, an air inlet dedusting filter screen, an activated carbon filter layer, an air outlet dedusting filter screen, an air outlet switch seal valve and an induced draft fan which are successively arranged in the housing; a plurality of activated carbon heating devices are arranged in the activated carbon filter layer which is also connected to a vacuum pump. The vacuum pump is also connected to a combustion catalyst. The filter element replacement-free air purifying equipment disclosed by the invention has a function of regenerating activated carbon. When the activated carbon in the equipment reaches adsorption and saturation, the activated carbon can be automatically regenerated, so that problems of physical adsorption and saturation, secondary pollution, high using cost and the like are avoided. Through verification, contents of formaldehyde, benzene, methylbenzene and the like in indoor air are remarkably reduced if the air is treated by the filter element replacement-free air purifying equipment. The filter element replacement-free air purifying equipment disclosed by the invention is high in purifying efficiency and can operate continuously for a long time, avoids the defects, such as adsorption and saturation and secondary pollution, of other air purifiers, and achieves the purpose of purifying indoor air.

Description

technical field [0001] The invention relates to an air purification device, in particular to an air purification device without replacing filter elements. Background technique [0002] With the improvement of people's living standards and the development of society, air quality has attracted more and more attention. The content of formaldehyde, benzene, toluene, xylene, TVOC, etc. in the air often exceeds the standard. The excessive content of these harmful gases often causes red eyes, itchy eyes, throat discomfort or pain, hoarse voice, sneezing, chest tightness, asthma, dermatitis, etc. The current air purification methods include filtration, photocatalysis, oxidation and other methods. In the filtration method, a variety of filter components including activated carbon filters and HEPA high-efficiency filter membranes are used to purify the air. The main principle of activated carbon filter adsorption and filtration is to use the filter The adsorption holes on the watch e...
