Abstract
The invention discloses a method for purifying indoor air by means of a fan. A filter net is arranged at an air outlet of the fan. The filter net is provided with a connecting piece and can be fixedly connected with a front mesh enclosure of the fan. The filter net is provided with a filtration purification unit. Circulated air is processed through the filtration purification unit. The filtration purification unit comprises a first adsorption component, a catalytic component and a second adsorption component which are stacked in a front-back mode. A catalyst can remove benzene, methylbenzene, dimenthylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acraldehyde in air to make the concentration smaller than 0.05 microgram/cubic meter, and meanwhile the content of microorganisms in circulating gas is remarkably lowered.
Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of method utilizing fan to purify the air of a room.
Background technology
At present, along with expanding economy, domestic big city haze weather gets more and more, and along with increasing of haze weather, the quality of room air also declines thereupon.
Haze, also claims the particle such as dust, sulfuric acid, nitric acid, organic hydrocarbon compounds in gray haze (smog) air that air also can be made muddy.The horizontal visibility of object is called mist or mist (Mist) in this phenomenon of 1000-10000 rice.Formed mist time atmospheric humidity should be saturated (when existing if any a large amount of nuclei of condensation, relative humidity not necessarily reach 100% just may occur saturated).Due to the mist scattering of aqueous water or ice crystal composition light and wavelength relationship not quite, thus mist seems to be creamy white or Bluish white and grey.Sulfur dioxide, nitrogen oxide and pellet are the main compositions of haze.
The harm that haze produces human body is as follows:
(1) on the impact of respiratory system
The constituent of haze is very complicated, comprises hundreds of Atmospheric Chemistry particulate matter.The particulate that the mainly diameter be wherein harmful to health is less than 10 microns, as mineral grain thing, sea salt, sulfate, nitrate, Organic aerosol particle, fuel and automobile exhaust gas etc., it directly can enter and stick in human respiratory tract and alveolar.Especially submicron particle can be deposited in upper and lower respiratory tract and alveolar respectively, causes the illness such as acute rhinitis and acute bronchitis.For chronic respiratory disease patients such as bronchial astehma, chronic bronchitis, obstructive emphysema and COPDs, haze weather can make state of an illness acute attack or acute exacerbation.If be in this environment for a long time also can bring out lung cancer.
(2) on the impact of cardiovascular system
Haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, normal blood circulation can be hindered, cause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, angina pectoris, miocardial infarction, heart failure etc. may be brought out, make chronic bronchitis occur cor pulmonale etc.
In addition, thick fog weather pressure ratio is lower, and people can produce a kind of sensation of agitation, and blood pressure can increase naturally to some extent.On the one hand often temperature is lower the greasy weather again, and some hypertension, patients with coronary heart disease go to suddenly cold outdoor from warm indoor, blood vessel expands with heat and contract with cold, and blood pressure also can be made to raise, cause the generation of apoplexy, myocardial infarction.The careful reply so heart and brain blood patient must take medicine on time.
(3) haze weather also can cause that surface layer is ultraviolet to be weakened, and make the increased activity of the infectiousness germ in air, infectious disease increases.
(4) child growth is unfavorable for.Because sunshine in greasy weather reduces, children's Ultraviolet radiation is not enough, and in body, vitamin D generates not enough, greatly reduces, serious meeting causes Infant Rickets, children growth slows down to the absorption of calcium.
Meanwhile, along with the raising of people's living standard, the interpolation of interior decoration, new furniture also significantly increases.But in interior decoration and furniture, inevitably use various glue or paint, thus cause distributing various organic pollution to indoor, the such as material such as formaldehyde, benzene.
At present, for the process of these indoor pollutants, be mostly to adopt various air purifier and charcoal absorption etc., but the increase of these equipment, careat can be taken, thus increase cost.
Existing fan, is only used to rotary air, brings the circulation of air, and the fan of market does not have any purification function.
So how utilizing existing fan, purify room air, is one of this area problems faced.
Summary of the invention
The object of the invention is to propose one and utilize existing fan, also catalysis is carried out to air, by the harmful substance in air, such as nitrogen oxide, oxycarbide, organic odor contamination such as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde etc., carry out decomposing, being oxidized or/and adsorb, bactericidal purifying is carried out to air, ensures indoor air cleaning.
For reaching this object, the present invention by the following technical solutions:
A kind of method utilizing fan to purify the air of a room, it arranges screen pack at fan outlet place, described screen pack possesses connector, can be fixedly connected with the front mesh enclosure of fan, described screen pack possesses filtration, purification unit, the air circulated is through the process of described filtration, purification unit, and described filtration, purification unit comprises the first adsorption element, catalytic member and the second adsorption element that front and back superpose.
