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
Device structure design and air 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, causes 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 formaldehyde significantly affect the comfortable, healthy of people and operating efficiency.Volatility is organic
Thing causes stimulus to the sense organ to human body, so that human body sensory is dried, stimulates eye mucous membrane, schneiderian membrance, respiratory tract and skin etc.；Make one to produce
Headache, the discomfort such as weak, drowsy.The pollutants such as alcohol, aromatic hydrocarbon and aldehydes can produce thorn to mucous membrane and the upper respiratory tract
Swash；A lot of VOC such as benzene, tetrachloro-ethylene, trichloroethanes, trichloro ethylenes etc. may be related to cancer.
Additionally, formaldehyde is typical pollutant in China room.Oneself confirmation formaldehyde of the World Health Organization is carcinogenic and teratogenesis
Material, for potentially one of strong mutagen.Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, causes nasopharynx
Cancer, colon cancer, paramenia etc..Especially, formaldehyde is bigger for children, pregnant woman's harm, may result in the pregnancy syndrome of pregnant woman,
Cause neonatal chromosome disorder, leukaemia so that teenager's memory and intelligence decline etc..
The time more than 80% in life of people lives indoors.Therefore, the pollutants 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 sorbing material
Adsorption capacity is limited, often needs sorbing 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 clarifier is shorter, and frequent sorbing 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 the commonly used method of skilled person that sorbing material is desorbed using heating, in order to overcome adsorption cleaning
Device needs frequently to change the defect of sorbing material, and the method according to sorbing material heating desorption, currently has open source literature to record
Integrate the new-type adsorption cleaning device with thermal desorption function, such as number of patent application is：201510898501.0 a kind of base
In wall-mounted air purification device and its purification method of hot recycling, user selects to indoor purifying or force ventilation as needed,
When selecting to indoor purifying function, blowdown after thermal desorption will be carried out in the course of work, when tool ventilation function is selected a good opportunity in choosing, by room
Outer Leads to new breeze is indoor, but this wall-mounted air purification device and its purification method have following defect：(1) because only that heating
During desorption (hot recycling mode period), be possible to pressure in closing closed cabin excessive, and due to anti-device damage relief valve
The air purifying room of closed cabin being arranged on clarifier on indoor wall, once therefore relief valve open pressure release, just will in cabin dirt
The high air of dye thing concentration is let out to interior, makes indoor composition secondary pollution, and when between air purifying room and thermal regeneration room
Air valve be closed and thermal regeneration room lead to outdoor air valve be closed, that is, clarifier is in purification
During pattern, the electrical heating wire heating control circuit out of control generation high temperature indoor to thermal regeneration, and the indoor temperature of thermal regeneration
Sensor damages again, and the pressure of the thermal regeneration interior generation now closed is possible to excessive and damages device, because this moment
It is arranged on air purifying room can not possibly work to relief valve on indoor wall；(2) can not will adsorb the ash on low efficient filter
Dirt is arranged to outdoor；(3) the air valve being provided in air purifying room top because opening under blowdown pattern, and close and be provided in
The air valve of air purifying room bottom, therefore the air containing pollutant of air cleaning interior desorption can not possibly be completely exhausted out, and also may be used
Can arrange to interior, form secondary pollution；(4) the air valve being provided in air purifying room bottom because opening under fresh air pattern, and
Close the air valve being provided in air purifying room top, therefore after outdoor fresh air can not possibly purify through filtering module in duct main
Introduce indoor, but purify straight-through interior without filtering module；(5) because using pure timing blowdown, timing there may be long
Or too short, such as winter there may exist the overlong time of timing, and summer there may exist the heat that time of timing crosses in nacelle and dissipates
Not.

(2),
(2) the deliming stage, control processor unit controls blower fan antiport by control signal, makes air cleaning indoor
Air-flow from top to bottom flows, and room air, through set air channel air inlet clean room on air cleaning chamber upper wall, from top to bottom flows
Dynamic, with outside atmosphere on air channel set by thermal insulation board lower end between heated regeneration room and air purifying room to thermal regeneration room bulkhead
Communicate set air channel, arrange to outdoor, thus the dust adsorbing on low efficient filter is entered outside atmosphere, treat deliming stage running
Time reaches and enters ventilating stage (1) during 10min；
3) when the cleansing phase of purification pattern and the ventilating stage of fresh air pattern run, control processor unit passes through stream
Quantity sensor is continued to monitor to air mass flow in cabin and is compared with the air mass flow threshold values setting, when monitoring that air mass flow is less than
Air mass flow threshold values 80% when, assert air purifier in air flow not smooth, control processor unit carries out alarm.
Compared with prior art, clarifier proposed by the present invention has following significant beneficial effects：
The clarifier of the present invention and its air purification method achieve and not only realize efficiently renewable VOCs and formaldehyde are inhaled
Enclosure material is desorbed, also to low efficient filter deliming, because ensure that blowdown with timing plus temp measuring method control of sewage disposal time length
Terminate temperature and indoor temperature in cabin to be adapted, and because relief valve is installed on the bulkhead of thermal regeneration room by through wall
Be connected with outside atmosphere it is achieved that whenever temperature control cause cabin inner high voltage can pressure release, and will not be to room during pressure release
If interior form secondary pollution it is achieved that when the ventilating stage of the cleansing phase of purification pattern and fresh air pattern runs flow not smooth
Carry out alarm.Structure is simple, a kind of easy to operate, safety and stability, there is provided permanently effective mode purifying the air of a room.
