Description
Technical field
The invention belongs to Techniques for Indoor Air Purification field, purify particularly to a kind of wall hanging type air with hot recycling
Device structure design and its purification method.
Background technology
With the high speed development of Chinese Urbanization, the newly-built enormous amount of annual building, increasing Novel decoration material
And chemical products are applied to interior decoration dress and drill.It is organic that these new indoor finishing materials often discharge a large amount of volatility
The pollutant such as thing (vocs) and formaldehyde, cause serious indoor pollution.According to statistics, after finishing, formaldehyde and vocs in newly constructed house
Content major part is exceeded.
Volatile organic matter (vocs) and comfortable, the healthy and work efficiency of formaldehyde appreciable impact people.Volatility is organic
Thing causes stimulus to the sense organ to human body, so that human body sensory is dried, stimulates eye mucosa, nasal mucosa, respiratory tract and skin etc.；Make one to produce
Headache, the discomfort such as weak, drowsy.The pollutant such as alcohol, aromatic hydrocarbon and aldehydes can produce thorn to mucosa and upper respiratory tract
Swash；A lot of VOC such as benzene, tetrachloroethylene, trichloroethane, trichloro ethylenes etc. may be related to cancer.
Additionally, formaldehyde is typical pollutant in China room.Oneself confirmation formaldehyde of World Health Organization (WHO) is carcinogenic and teratogenesis
Material, for potentially one of strong mutagen.Long Term Contact low dosage formaldehyde can cause chronic respiratory tract disease, causes nasopharynx
Cancer, colon cancer, menoxenia etc..Especially, formaldehyde is bigger for child, anemia of pregnant woman's harm, may result in the pregnancy syndrome of anemia of pregnant woman,
Cause neonatal chromosome disorder, leukemia so that teenager memory and intelligence decline etc..
The time more than 80% in life of people lives indoors.Therefore, the pollutant such as indoor vocs and formaldehyde are carried out
Purify particularly necessary.For this reason, it may be necessary to choose suitable air purifier to eliminate the harm to human body for these indoor pollutants.
Current indoor purification techniques mainly includes ventilation, absorption, photochemical catalytic oxidation and plasma technology etc..Wherein adsorption material
Expect, the no advantage such as harmful side product relatively low due to having cost, be most widely used in the market.However, due to adsorbing material
Adsorption capacity is limited, often needs adsorbing material to be taken out to be desorbed, otherwise will have a strong impact on clean-up effect, and make adsorption air
The life cycle of depurator is shorter, and frequent adsorbing material of changing bothers.When this makes adsorption cleaning device be difficult to realize longer
Between application.Therefore, need solution this key issue of adsorbent saturation in technique badly.
It is known that: it is the commonly used method of skilled person that adsorbing material is desorbed using heating, in order to overcome
Adsorption cleaning device needs frequently to change the defect of adsorbing material, and the method according to adsorbing material heating desorption, currently has public affairs
Open document and record the new-type adsorption cleaning device integrating with thermal desorption function, such as number of patent application is:
201510898501.0 a kind of wall-mounted air purification device based on hot recycling and its purification method, user selects as needed
To indoor purifying or force ventilation, when selecting to indoor purifying function, in work process, blowdown after thermal desorption will be carried out, be elected to
Select a good opportunity tool ventilation function when, will outdoor fresh air introduce indoor, but this wall-mounted air purification device and its purification method exist as follows
Defect: (1) because only that in heating desorption (hot recycling mode period), being possible to pressure in closing closed cabin excessive, and by
Be arranged in anti-device damage relief valve depurator closed cabin air purifying room to indoor wall on, once therefore relief valve
Open pressure release, just let out air high for Cabin contamination thing concentration to interior, make indoor composition secondary pollution, and work as air cleaning
Air cock between room and thermal regeneration room is closed and thermal regeneration room is led to outdoor air cock and is in closing shape
State, when that is, depurator is in purification pattern, the electrical heating wire heating control circuit out of control generation high temperature indoor to thermal regeneration, and
The indoor temperature sensor of thermal regeneration damages again, the pressure of the indoor generation of the thermal regeneration now closed be possible to excessive and
Damage device, because be arranged on air purifying room can not possibly work to relief valve on indoor wall this moment；(2) can not will adsorb
Dust on low efficient filter is arranged to outdoor；(3) the air being provided in air purifying room top because opening under blowdown pattern
Valve, and close the air cock being provided in air purifying room bottom, therefore the air containing pollutant of air cleaning interior desorption can not
Can be completely exhausted out, it is also possible to arrange to interior, forming secondary pollution；(4) it is provided in air cleaning because open under fresh air pattern
The air cock of room bottom, and close the air cock being provided in air purifying room top, therefore outdoor fresh air can not possibly be through air channel master
Introduce indoor after filtering module purifies in body, but purify straight-through interior without filtering module；(5) because using pure timing blowdown, fixed
When the time there may be long or too short, such as winter there may exist the overlong time of timing, and summer there may exist timing
The heat that time passes in nacelle does not dissipate.
Content of the invention
The purpose of the present invention is for overcoming oneself to have the weak point of technology, proposing a kind of wall hanging type air with hot recycling
Depurator and its purification method, have and will not control row to indoor formation secondary pollution with timing plus temp measuring method during pressure release
Dirty time length, selects first to carry out automatic deliming process to air purifier when opening corresponding modes, treats that automatic deliming processes knot
Bundle enters the selected pattern opened.
Automatically remove on filter dust function and
In order to realize above-mentioned purpose, the technical scheme is that
A kind of wall-mounted air purification device with hot recycling, comprising: closed cabin, blower fan, the first automatically controlled air cock to
