Description
Technical field
The present invention provides a kind of removable heating adsoption catalysis module, belongs to field of air purification device.
Background technology
At present, in room air, gaseous contaminant is mainly derived from indoor decorating and refurnishing materials, especially with wood-based plate for very, wraps
Including plywood, core-board, medium density fibre board (MDF) and particieboard etc., main cause is that this type of finishing material employs urea-formaldehyde resin
As binding agent, Lauxite in use can the slow gaseous contaminant such as release formaldehyde, time span is up to many decades.
Its rate of release under the conditions of hot and humid of what is more important can substantially be accelerated, and is Summer Indoor formaldehyde in air, TVOC etc.
The main source of gaseous contamination chemicals.All kinds of decoration materials such as wall paper, wallpaper, paint, coating etc. and floor glue, mould
Veneer, plywood, emulsion paint, synthetic fibers, binding agent etc. all can discharge formaldehyde.
Zhuan Xiaohong (Zhuan Xiaohong. the release rule research [D] of Indoor decoration and typical pollutant；Northeastern University,
2010.) choose that market, supermarket, household city, board library, cinema, railway station waiting room 6 class be representational large-scale and super large
Totally 18 relative analyses of type indoor public places sum up the pollution regularity of distribution of indoor public places.A () typical indoor is public
Place each index exceeding standard situation is relevant with functional areas in place, and chemical index is mainly with carbon dioxide, ammonia, formaldehyde, TVOC
And benzopyrene (BaP) to exceed standard be main, and have its each source of release and release rule, in place, the concentration of these indexs is by temperature
Impact etc. physical property index.B () Newly decorated rooms formaldehyde in indoor air exceeds standard seriously, exceeding standard rate is 80%, the highest exceeds standard
Nearly 10 times.Benzene homologues is with the pollution of toluene and dimethylbenzene as principal character, and benzene exceeding standard rate is 2%, pollutes the most universal；Toluene exceeds standard
10%；Dimethylbenzene exceeds standard 23%.In the non-Newly decorated rooms of one hundred houses, formaldehyde pollution is the most extremely serious, and exceeding standard rate is 62%.Surpassing of benzene
Mark rate is still 2%, and the exceeding standard rate of toluene and dimethylbenzene is all down to 3%, pollutes and does not the most have universality, and therefore benzene homologues does not have length
Reach the pollution timeliness of several years.(c) respectively choose 50 families fit up 1 week, 1 month, its room air carries out by the room of more than 3 months
VOCs detects, and finds that VOCs concentration is gradually lowered with the prolongation of finishing time, and after 3 months, exceeding standard rate reduces to 26% from 68%.3
The VOCs component still suffered from after Yue 59 kinds, wherein 31 kinds have pollution universality, and in component, great majority are toxicant.(d) with
Formaldehyde, benzene homologues are that object of study carries out release rule by cycle or time period in climate box and analysis of Influential Factors finds:
Different plates source PARA FORMALDEHYDE PRILLS(91,95), benzene homologues release rule do not make significant difference, and rise high-temperature and can accelerate the release speed of formaldehyde, benzene homologues
Rate, the release changing humidity PARA FORMALDEHYDE PRILLS(91,95) and benzene homologues does not makes significant difference, new wind be passed through the release rule that can temporarily change formaldehyde
But the deenergized period of benzene homologues will not be shortened.Form aldehyde release has chronicity, and by calculating medium finishing, 15m2Left and right
In room, Form aldehyde release at least needs about 16 years.
Currently for purified treatment many employings air purifier of gaseous contaminant in room air, it is at formaldehyde and TVOC
In processing procedure, many employing absorption filter element especially activated carbon adsorption filter elements are main, generally with column charcoal filled honeycomb plate, coconut husk
Particles filled cellular board, spherical carbon filled honeycomb plate are main.Core Feature material used by this kind of processing mode mainly activity
Charcoal, uses the initial stage can reach preferable clean-up effect at depurator, owing in air, exhaust gas constituents is complicated, and the absorption of activated carbon
Finite capacity, i.e. can reach saturation in the shortest time, on the one hand makes depurator lose its original performance, and What is more
Depurator itself can be caused to become waste gas volatile source, give and use environment to cause secondary pollution.In addition, directly by seed activity
The filter element that charcoal (30～60 mesh) prepares with the gluing compound suppressing of non-woven fabrics is also currently used main flow filter element, such as PHILIPS Co.
AC4076 air purifier i.e. uses such pattern, but is combined because this filter element is many with HEPA filter cloth, and HEPA filter cloth is because holding dirt
Measuring limited is affected greatly by humidity, and then the related active carbon filter core replacement cycle shortens.
In sum, it is too short the most all to there is the life-span in traditional air purifier, and filter element needs that frequently changes to lack
Falling into, use cost is too high.
Summary of the invention
