Description
Technical field
The invention belongs to Techniques for Indoor Air Purification field, purify particularly to a kind of wall hanging type air based on hot recycling
The design of device structure and purification method thereof.
Background technology
Along 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 exceeds standard.
Volatile organic matter (VOCs) and comfortable, the healthy and work efficiency of formaldehyde appreciable impact people.Volatility is organic
Human body is caused stimulus to the sense organ by thing, makes human body sensory be dried, exciting eye mucosa, nasal mucosa, respiratory tract and skin etc.；People is made 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；Such as benzene, tetrachloroethylene, trichloroethane, trichloro ethylene etc. may be relevant to cancer for a lot of VOCs.
Additionally, formaldehyde is typical pollutant in China room.Oneself confirmation formaldehyde of World Health Organization (WHO) is carcinogenic and teratogenesis
Material, for one of potential 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 degradation under teenager memory and intelligence.
Time more than 80% in life of people lives in indoor.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 of these indoor pollutants.
Current indoor purification techniques mainly includes ventilation, absorption, photochemical catalytic oxidation and plasma technology etc..Wherein adsorption material
Expect relatively low owing to having cost, without advantages such as harmful side products, be most widely used in the market.But, due to adsorbing material
Adsorption capacity is limited, 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 frequently changes adsorbing material trouble.When this makes adsorption cleaning device be difficult to realize longer
Between application.Therefore, solution adsorbent this key issue saturated in technique is needed badly.
It is known that: adsorbing material is used that to add thermal desorption be the commonly used method of skilled person, in order to overcome
Adsorption cleaning device needs frequently to change the defect of adsorbing material, and the method adding thermal desorption according to adsorbing material, currently has public affairs
Open document record and integrate the new-type adsorption cleaning device with thermal desorption function, as number of patent application is:
201510898501.0 a kind of based on hot recycling wall-mounted air purification device and purification method, user selects as required
To indoor purifying or force ventilation, when selecting indoor purifying function, work process will carry out blowdown after thermal desorption, elected
Select a good opportunity tool ventilation function time, by indoor for outdoor Leads to new breeze, but this wall-mounted air purification device and purification method thereof exist as follows
Defect: (1) because only that when adding thermal desorption (hot recycling mode period), its is possible to pressure in closing closed cabin excessive, again by
The air purifying room of closed cabin of depurator it is arranged on indoor wall in anti-device damage relief valve, therefore once relief valve
Open pressure release, just air high for Cabin contamination substrate concentration is let out to indoor, 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 closedown shape
State, when i.e. 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 thermal regeneration indoor generation now closed the most excessive and
Damage device, can not work because be arranged on air purifying room relief valve on indoor wall this moment；(2) can not will adsorb
Dust on low efficient filter is arranged to outdoor；(3) because of the air being provided in air purifying room top opened under blowdown pattern
Valve, and close the air cock being provided in bottom air purifying room, thus air cleaning indoor desorption can not containing pollutant air
Can be completely exhausted out, it is also possible to row, to indoor, forms secondary pollution；(4) it is provided in air cleaning because of open under new wind pattern
Air cock bottom room, and close the air cock being provided in air purifying room top, therefore outdoor new wind can not be through air channel master
Introduce indoor after filtering module purifies in body, but purify straight-through indoor without filtering module；(5) because using pure timing blowdown, fixed
Time the time there may be long or too short, as there may exist winter timing overlong time, there may exist summer timing
The heat that time passes in nacelle does not dissipates.
Summary of the invention
It is an object of the invention to, for overcoming oneself to have the weak point of technology, propose a kind of wall hanging type air based on hot recycling
Depurator and purification method thereof, when there is pressure release will not to indoor formation secondary pollution and automatically except on filter dust function with
And add temp measuring method control of sewage disposal time length with timing.
In order to realize above-mentioned purpose, the technical scheme is that
A kind of wall-mounted air purification device based on hot recycling, including: closed cabin, blower fan, the first automatically controlled air cock to
