Abstract

The utility model relates to a cleaning device which is especially used for purifying volatile organic matter in indoor air. An active carbon filtration layer is arranged between an air inlet and a clean air outlet. The thickness of the adsorption layer of granular activated carbon is greater than 5 centimeters and the filtration layer is coated by a filtration layer with high efficiency The utility model can improve contaminated indoor air quality and effectively improve health level of people.

Description

Air cleaning unit
The utility model is a kind of air cleaning unit, particularly is specifically designed to the purifier of volatile organic matter in purifying the air of a room.
Existing indoor air purification technology mainly contains two classes, and a class is anion and ozone generation technology; Another kind of is the high efficiency filter technology.Anion and ozone generation technology are to rely on electronic installation to produce anion and ozone, allow the electric charge of ozone ion in conjunction with airblrne particulates, thereby the suspended particles in gathering and the settle air (being dust), pollute for airborne smell or other organic matters, it relies on the oxidation of ozone to carry out oxidation, thereby reaches the purpose of removing organic matter pollution in the air.The shortcoming of this clarifier is that ozone itself also is a kind of harmful substance, even under low concentration, the people is also arranged to ozone allergy.Its ability that purifies air is also very poor, and to the volatile organic matter (VOC) of low concentration, when 10ppb was following, ozone can't react with these organic matters as most of organic concentration, thereby did not remove the effect of these materials.The high efficiency filter technology is to adopt a kind of high efficiency particulate air filter (HEPA), and this filter has the high efficiency filter layer, can remove airborne suspended particulate substance (being dust) effectively, and the dust rate of removing reaches 99%.But the major function of this filter be remove dust and with particle like the dust-like, as pollen, fiber fines, part mould etc.It does not have the purification filtering ability to volatile organic matter in the room air.Though some HEPA air purifier has increased the material that partially absorbs smell,, thereby can not remove the volatile organic matter in the room air effectively because the adsorption area of these materials is limited.In sum, in the existing indoor air cleaner, do not have a kind ofly can be used for special purifying volatile organic compound, volatile organic matter then causes the biggest factor of room air pollution exactly, particularly newly-decorated room, VOC is the subject matter that is detrimental to health.
The purpose of this utility model is, overcome the shortcoming of above-mentioned air cleaning unit structure, provide a kind of novel air purifier at volatile organic matter in the room air (VOC), the volatile organic matter of low concentration in purifying the air of a room specially, thereby solve existing air purifier and can not effectively solve airborne low concentration VOC problem, purify air, ensure human health.
The purpose of this utility model is to realize like this.Air cleaning unit includes housing, and housing bottom surface or side have air intake place 1, and housing top or side have clean air outlet 4 and electronic control part 5, also has activated carbon filter layer 3 between air intake place 1 and clean air outlet 4.
The adsorbent layer thickness of granular active carbon must be greater than 5 centimetres; Can be enclosed with high efficiency filter layer 2 outside the activated carbon filter layer 3.
Housing top can have direction control 6.
Air purifier can manufacture the vertical type cylinder shape, also can be rectangular formula or positive mode box structure.No matter adopt which kind of structure, the adsorbent layer thickness of its granular active carbon must be greater than 5 centimetres.
The present invention adopts the mode of flow filtration to purify the air of a room.By efficient pump drainage blower fan room air is sucked clarifier, cleaned air passes is discharged by exhaust outlet.The core of clarifier is an absorption inner core that the sp act charcoal is housed, and the thickness of this special absorption inner core must can hold the granular active carbon greater than 5000 grams, so that the gas that passes through has enough time of staying on active carbon greater than 5 centimetres.Otherwise effective adsorption of Low Concentration volatile organic matter (VOC).Air purifier can arbitrarily move indoor, and the mode that sucks air can be from all directions, can be from bottom surface, the side air inlet of cylinder, and from the top or the side exhaust, also can be from the bottom surface or the side air inlet of box-shaped, from the exhaust of top rear face.Gas is key of the present invention at enough residence times of adsorption layer.The design and the design of this a large amount of activated carbon adsorption layers that adopt for the VOC of adsorption of Low Concentration are that present any air purifier is unexistent.Be specifically designed to the pollution of the VOC (volatile organic matter) of cleaning room air with the air purifier of the design's manufacturing, it can be with most VOC absorption of indoor pollution air, remove.Even import VOC concentration is about 10ppb, also can reach 90% the purifying rate of removing VOC.This air purifier is used for indoor air purification,, can effectively improves level of human health improving the IAQ that has polluted greatly.
The utility model is provided by following examples and accompanying drawing thereof.
Accompanying drawing 1 is the cylindric purifier structural representation of the utility model.
Accompanying drawing 2 is the utility model rectangle purifier structural representations.
1 air intake place, 2 high efficiency filter layers, 3 activated carbon filter layers, 4 clean air outlets, 5 Electronic Control, the control of 6 directions.
Embodiment 1: see accompanying drawing 1.
Air cleaning unit is designed to a kind of cylindric clarifier, includes housing, and is high 50 centimetres, 38 centimetres of diameters; The housing bottom surface has air intake place 1, and housing top has clean air outlet 4 and electronic control part 5, direction control 6.Dress ring-type activated carbon filtration absorbent core 3 between air intake place 1 and clean air outlet 4.Filter course 3 is wrapped with high efficiency filter layer 2.The adsorbent layer thickness of granular active carbon must be greater than 5 centimetres; Particle size is the 2-8 order, and loadings is 9080 grams, and air-breathing and air exhauster ability is the 14--25 cubic meters per minute.Air-flow enters from the bottom, through annular activated carbon adsorption layer, gets rid of from the clarifier top-side again.When using this clarifier, directly test in import (bottom) contaminated air VOC concentration and the outlet VOC concentration that purifies air, its concentration is, benzene drops to 0.3ppb from 2.0ppb, and toluene drops to 0.5ppbv from 20ppbv, and other organic matter is removed more than 90% respectively.
Embodiment 2: see accompanying drawing 2.
Air purifier is a kind of rectangle clarifier, is of a size of 50 centimetres of 30 cm x, 33 cm x.Case side has been worn air porch 1, has clean air outlet 4 above the housing.Other structures are the same.Air sucks from a side, purify the back air from directly over send.Activated carbon adsorption layer is 7 centimetres of 27 cm x, 30 cm x, interior dress coconut shell mould active carbon 9080 grams.Active carbon is a graininess, particle diameter 2-8 order.Suction tolerance is the 15-20 cubic meter.Activated carbon filter layer does not wrap up the high efficiency filter layer outward, and other structure is the same.This clarifier is placed one 12 square metres office, volatile organic matter carrene 10ppb is arranged in the former air of office, benzene 5ppb, toluene 12ppb, tetrachloro-ethylene 5ppb, other organic alkane 20ppb.After running in a day 24 hours, carrene is reduced to 0.5ppb, and benzene is less than 0.2ppb, and toluene is less than 2ppb, and tetrachloro-ethylene is less than 0.5ppb, and other organic alkane is less than 5ppb.
