Description
Technical field
The invention belongs to Techniques for Indoor Air Purification field, in particular to a kind of wall hanging type air purification based on hot recycling
The design of device structure and its purification method.
Background technique
With the high speed development of Chinese Urbanization, annual building creates enormous amount, more and more Novel decoration materials
And chemical products are applied to interior decoration dress and drill.It is organic that these new indoor finishing materials often release a large amount of volatility
The pollutants such as object (VOCs) and formaldehyde, cause serious indoor pollution.According to statistics, after finishing, formaldehyde and VOCs in newly constructed house
Content is largely exceeded.
Volatile organic matter (VOCs) and formaldehyde significantly affect comfortable, the healthy and working efficiency of people.Volatility is organic
Object causes stimulus to the sense organ to human body, keeps human body sensory dry, stimulation eye mucous membrane, schneiderian membrance, respiratory tract and skin etc.；It makes one to generate
The discomfort such as headache, out of strength, drowsy.The pollutants such as alcohol, aromatic hydrocarbon and aldehydes can generate thorn to mucous membrane and the upper respiratory tract
Swash；Many volatile organic compounds such as benzene, tetrachloro-ethylene, trichloroethanes, trichloro ethylene etc. may be related to cancer.
In addition, formaldehyde is typical pollutant in China room.Oneself confirmation formaldehyde of the World Health Organization is carcinogenic and teratogenesis
Substance, for one of potential strong mutagen.Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, cause nasopharynx
Cancer, colon cancer, paramenia etc..Particularly, formaldehyde is bigger for children, pregnant woman's harm, can lead to the pregnancy syndrome of pregnant woman,
Cause neonatal chromosome disorder, leukaemia, so that teenager's memory and intelligence decline etc..
People be more than in life 80% time life indoors.Therefore, the pollutants such as indoor VOCs and formaldehyde are carried out
It purifies particularly necessary.For this reason, it may be necessary to choose suitable air purifier to eliminate harm of these indoor pollutants to human body.
Current indoor purification techniques mainly includes ventilation, absorption, photochemical catalytic oxidation and plasma technology etc..Wherein adsorption material
Material due to have cost is relatively low, the advantages such as no harmful side product are most widely used in the market.However, due to adsorbent material
Adsorption capacity is limited, and adsorbent material will often be taken out by, which needing, is desorbed, and otherwise will seriously affect clean-up effect, makes adsorption air
The life cycle of clarifier is shorter, and frequently replacement adsorbent material trouble.When this makes adsorption cleaning device be difficult to realize longer
Between application.Therefore, it needs the solution adsorbent in technique and is saturated this critical issue.
It is known that: using heating desorption to adsorbent material is the method that skilled person generallys use, in order to overcome
Adsorption cleaning device needs to frequently replace the defect of adsorbent material, and according to the method for adsorbent material heating desorption, currently there is public affairs
It opens document and records the new-type adsorption cleaning device integrated with thermal desorption function, such as number of patent application are as follows:
201510898501.0 a kind of wall-mounted air purification device and its purification method based on hot recycling, user selects as needed
To indoor purifying or force ventilation, when selection is to indoor purifying function, blowdown after thermal desorption will be carried out in the course of work, will be elected to
Select a good opportunity tool ventilation function when, outdoor fresh air is introduced it is indoor, but the wall-mounted air purification device and its purification method exist it is as follows
Defect: (1) because only that when (hot recycling mode period) is desorbed in heating, closing that be possible to pressure in closed cabin excessive, and by
The air purifying room of the closed cabin of clarifier is mounted on relief valve in anti-device damage on indoor wall, once therefore relief valve
Pressure release is opened, just the highly concentrated air of Cabin contamination object is let out to interior, makes indoor composition secondary pollution, and work as air cleaning
Air valve between room and heating regeneration room is in close state and heats regeneration room and leads to outdoor air valve in closing shape
When state, i.e. clarifier are in purification pattern, indoor electric heating wire heating control circuit generation high temperature out of control is regenerated to heating, and
Heating regenerates indoor temperature sensor and damage again, at this time the pressure of the closed interior generation of heating regeneration room be possible to it is excessive and
Device is damaged, because being mounted on air purifying room relief valve on indoor wall this moment can not work；(2) cannot will adsorb
Dust on low efficient filter is arranged to outdoor；(3) because what is opened under blowdown mode is the air being arranged at the top of air purifying room
Valve, and closing is the air valve of air purifying room bottom to be arranged in, therefore the air containing pollutant being desorbed in air cleaning room can not
It can be completely exhausted out, it is also possible to arrange to interior, form secondary pollution；(4) because what is opened under fresh air mode is arranged in air cleaning
The air valve of room bottom, and closing is the air valve being arranged at the top of air purifying room, therefore outdoor fresh air can not be through air duct master
Interior is introduced in body after filtering module purification, but purifies straight-through interior without filtering module；(5) fixed because using pure timing blowdown
When the time there may be too long or too short, if winter there may be the overlong time of timing, summer there may be timing
The heat that time passes in nacelle does not dissipate.
Summary of the invention
The purpose of the present invention is propose a kind of wall hanging type air based on hot recycling to overcome oneself to have the shortcoming of technology
