Description

A kind of wall-mounted air purification device and its implementation

Technical field

The invention belongs to Techniques for Indoor Air Purification field, the wall-mounted air purification device structure of more particularly to hot recycling is set Meter and its implementation.

Background technology

With the high speed development of Chinese Urbanization, the annual newly-built enormous amount of building, increasing Novel decoration material And chemical products are applied to interior decoration dress and drilled.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 is largely exceeded.

Volatile organic matter (VOCs) and formaldehyde significantly affect comfortable, the healthy and operating efficiency of people.Volatility is organic Thing causes stimulus to the sense organ to human body, dries human body sensory, stimulates eye mucous membrane, schneiderian membrance, respiratory tract and skin etc.；Make one to produce The discomfort such as headache, weak, drowsy.The pollutants such as alcohol, aromatic hydrocarbon and aldehydes can produce thorn to mucous membrane and the upper respiratory tract Swash；Many VOC such as benzene, tetrachloro-ethylene, trichloroethanes, trichloro ethylenes 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 Material, for one of potential strong mutagen.Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, trigger nasopharynx Cancer, colon cancer, paramenia etc..Especially, formaldehyde is bigger for children, pregnant woman's harm, can cause the pregnancy syndrome of pregnant woman, Cause neonatal chromosome disorder, leukaemia so that teenager's memory and intelligence decline etc..

The time life more than 80% in life of people is indoors.Therefore, the pollutants such as indoor VOCs and formaldehyde are carried out Purify particularly necessary.For this reason, it may be necessary to suitable air purifier is chosen 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 the advantage such as no harmful side product, is most widely used due to relatively low with cost in the market.However, due to sorbing material Adsorption capacity is limited, and sorbing material will often be taken out by, which needing, is desorbed, and otherwise will be had a strong impact on clean-up effect, and be made adsorption air The life cycle of clarifier is shorter, and frequently changes sorbing material trouble.When this make it that adsorption cleaning device is difficult to realize longer Between application.Therefore, this key issue of solution adsorbent saturation in technique is needed badly.

It is well-known:It is the method that skilled person generally uses that heating desorption is used to sorbing material, in order to overcome The defects of adsorption cleaning device needs frequently to change sorbing material, and the method being desorbed is heated according to sorbing material, currently there are public affairs Open document and record the new-type adsorption cleaning device integrated with thermal desorption function, as number of patent application is： 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 heating is desorbed (hot recycling mode period), close that to be possible to pressure in closed cabin excessive, and by In anti-device damage with relief valve be arranged on clarifier closed cabin air purifying room to interior wall on, once therefore relief valve Pressure release is opened, just the high air of Cabin contamination thing concentration is let out to interior, makes indoor composition secondary pollution, and work as purification of air Air valve between room and thermal regeneration room is closed and the air valve of outdoor is led in closing shape in thermal regeneration room When state, i.e. clarifier are in purification pattern, to the electrical heating wire heating control circuit generation high temperature out of control in thermal regeneration room, and Temperature sensor in thermal regeneration room damages again, in the thermal regeneration room now closed caused pressure be possible to it is excessive and Device is damaged, because being arranged on air purifying room this moment can not possibly work to relief valve on the wall of interior；(2) because using nothing Have by indoor/outdoor temperature-difference much, air initial temperature is indoor air temperature in cabin when proceeding by thermal desorption, so working as room When outer temperature is more than indoor temperature, it is impossible to using outside air temperature as air is initially warm in cabin when proceeding by thermal desorption Degree, that is, the air of outdoor high temperature can not be introduced when proceeding by thermal desorption in cabin, make air initial temperature and outdoor in cabin high The air themperature of temperature is consistent, therefore when outdoor temperature is more than indoor temperature, now using at the beginning of air in cabin when proceeding by thermal desorption Beginning temperature is the method for indoor air temperature, makes not save during desorption；(3) because that is opened under blowdown pattern is provided in air Air valve at the top of clean room, and the air valve for being provided in air purifying room bottom is closed, therefore be desorbed in purification of air room Air containing pollutant can not possibly be completely exhausted out, it is also possible to arranged to interior, formed secondary pollution；(4) because opening under fresh air pattern The air valve of air purifying room bottom is provided in, and closes the air valve being provided at the top of air purifying room, thus it is outdoor new Wind can not possibly introduce interior after filtering module purification in duct main, but purify straight-through interior without filtering module；Because Using pure timing blowdown, timing there may be it is long or too short, as winter there may exist the overlong time of timing, summer The heat that time of timing pass in nacelle is there may exist not dissipate；(6) do not have and other removed to adsorbing dust on low efficient filter Dirt function；Because thermal desorption need one or two hour, and use air purifier to during indoor air purification set when pair Indoor air purification institute's cumulative time reaches when needing desorption time of setting, and pause is adopted to indoor air purification, is desorbed Blowdown, it is well known that：It typically someone will exist in room when purifying room air, therefore can be influenceed during desorption blowdown is carried out Indoor people cannot breathe cleaned air.And it is well-known, only in purification of air or ventilation, air purifier just can work for interior Make under corresponding pattern, otherwise, air purifier is in holding state, waits user to open corresponding modes, i.e. purification of air Device selects purification pattern to open, then into the purification pattern course of work, used in holding state, wait corresponding modes operation, user Family selection fresh air pattern is opened, then into the fresh air pattern course of work；When user closes purification pattern and fresh air pattern, air is net Change device and enter holding state.

It is well-known:Indoor air temperature is typically below 40 DEG C, and otherwise people normally can not live indoors.
