Description
Technical field
The present invention relates to multicellular metal foil indoor gas filter in application and structure.
Background technology
At present along with the progress of construction material, the raising of energy-saving building technology level and construction standards, the seal of architectural exterior-protecting construction is become better and better, and indoor air environment quality more and more needs force ventilation.Along with the development of China's green building, and people are to the attention of indoor air quality, have and independently VMC is set in building, and indoor air quality monitoring system is set, according to the change of the various pollutant levels such as CO, particle, formaldehyde of indoor, in good time unlatching VMC or air cleaning unit, reach the object controlling indoor air quality and building energy conservation, but the VMC that there be limited evidence currently of has construction and installation such.
IAQ should come into one's own all the more, adopts the air purifier of Techniques for Indoor Air Purification manufacture to be just used widely.At present, air purifier reaches 27% in the popularity rate of the U.S., Japan 17%, Europe 42%, Korea S 70%, and China is less than 0.2%.Current existing air purifier producer and air purifier multifarious, but usual existing air purifier technology is simple, and function singleness, is difficult to the demand meeting user's higher standard.China starts late in air purifier market, and also immature, compared with developed countries, the popularity rate of Chinese air purifier is quite low, and the current domestic air purifier market base is lower, and environmental quality worse and worse.
Porous metal material is a kind of material being usually used in industrial gasses and filtering, its metal body is formed through high temperature sintering by microscopic, spherical body (being commonly called as powder), metal inside all directions are connected by fine aperture and form, be that a kind of high-quality is breathed freely steel, air or any gas can be made to permeate smoothly and to pass.But this material is used for the filtration of industrial gasses or liquid at present, be not applied in indoor air filtration.
Summary of the invention
The invention provides the application of a kind of multicellular metal foil in indoor gas filters and structure, enter indoor various gases to filter and to purify, and the exchange etc. of indoor gas, improve indoor air quality, reduce and pollute.
The application of multicellular metal foil of the present invention in indoor gas filters, multicellular metal foil can be the film or very thin platy structure that are made up of porous metal material.Multicellular metal foil can be that the metal being matrix phase by solid solution alloy is formed on material composition, can ensure that multicellular metal foil has flexibility like this, and in the 2.3rd of paper " progress of Ti-Al intermetallic compound porous material; river Yao etc.; Chinese material is in progress; the 29th volume, the 3rd phase, in March, 2010 " the, save the preparation technology describing a kind of Ti-Al intermetallic compound paper mold film simultaneously.Because the paper mold film of above-mentioned porous is made up of Ti-Al intermetallic compound, therefore multicellular metal foil is also a kind of material with rigidity simultaneously.The preparation method of flexible, porous metal forming is documented in the application documents of Chinese patent 201410608980.3, does not describe in detail at this.
Exactly because the various characteristics of above-mentioned multicellular metal foil, therefore wherein a kind of application mode described multicellular metal foil is located at the ventilating opening place of room inside/outside, enters indoor air filter outdoor.When outdoor air enters indoor by ventilating openings such as windows, air can filter impurity wherein, dust etc. by the microscopic pinholes in multicellular metal foil, then makes the air after purification enter indoor, reaches the object improving IAQ.
In order to improve the mobility of room air, avoid the pollution grows worse of room air self, described multicellular metal foil can be respectively equipped with in described ventilating opening place at least at two diverse locations in the interior space, and the division of air inlet and air outlet is done to the ventilating opening of diverse location.Simultaneously extractor fan can also be set at ventilating opening and/or air outlet place, to accelerate the circulation of air, enter indoor air simultaneously and to get back the filtration of multicellular metal foil, make indoor air remain clean like this.
Another kind of is be located on the gas passage of indoor air outlet device by described multicellular metal foil to the application mode of multicellular metal foil.Described air outlet device includes and is positioned at indoor ventilation fan, air-conditioning, air freshening device and combustion gas distribution apparatus etc., is located at by multicellular metal foil on the path of the gas such as air inlet, air outlet process, when air by time air is filtered.When multicellular metal foil is located on combustion gas distribution apparatus, can carry out contaminant filter to combustion gas, make combustion gas more clean, efficiency of combustion is higher, also can solve the insufficient problem of burning that general combustion gas fire hole out-of-shape and skewness cause simultaneously.
On this basis, the filtration body thickness of preferred multicellular metal foil is 5 ~ 200 μm, can have good guarantee like this to the light transmission of whole metal forming, and also can strengthen its flexibility, makes it more easily be connected with relevant device or fit.
Further, the filter opening average pore size of multicellular metal foil filtration body is 0.05 ~ 100 μm, and porosity is 15 ~ 70%, can remove the impurity that in gas, particle is greater than 0.1 μm like this, rejection reaches 99.99%, extremely effectively reduces the pollution effect of PM2.5.
Present invention also offers the structure of a kind of multicellular metal foil in indoor gas filters, comprising above-mentioned multicellular metal foil, comprise filtration body at described multicellular metal foil, and be located at the syndeton of filtration body edge for adapting with other device.
Wherein a kind of concrete structure is, described syndeton is the clamp structure adapted with the ventilating opening place screen window of room inside/outside.Described clamp structure can for can overturn the structure clamping screen window edge, or the independent structure that multicellular metal foil and screen window edge can be clamped, and can also be the hook structure hanging over screen window upper edge or its both sides of hook.
The another kind of structure of syndeton can be interface arrangment, and such as common draw-in groove connection or buckle connection etc., select accordingly according to different applied environments.
Preferably, be at least respectively equipped with described syndeton on the relative edge edge of the filtration body of multicellular metal foil, multicellular metal foil uniform force can be made like this, not easily accidental movement.
The application of multicellular metal foil of the present invention in indoor gas filters and structure, can carry out contaminant filter and gas purification to entering indoor various gases, and in the exchange of indoor gas, increase substantially indoor air quality, reduce air pollution.Test is learnt, the present invention can remove the particle that in air, particle is greater than 0.1 μm, and rejection reaches 99.99%, also can ensure enough gas property passed through simultaneously.
Below in conjunction with the detailed description of the invention of embodiment, foregoing of the present invention is described in further detail again.But this should be interpreted as that the scope of the above-mentioned theme of the present invention is only limitted to following example.Without departing from the idea case in the present invention described above, the various replacement made according to ordinary skill knowledge and customary means or change, all should comprise within the scope of the invention.
