Description
One, technical field
The present invention relates to a kind of air purifier and purposes, belong to daily life fields such as public health with photocatalyst and nano-antibacterial effect.
Two, background technology
Along with expanding economy, the environmental pollution that industrial production is brought is on the rise, and people's living space but is faced with great challenge.The outburst of spring and summer in this year " SARS " not only makes the economic development of human life security and society be subjected to great impact, has caused unprecedented fear on people.Because the sudden and infectiousness of breathing problem often makes people hard to guard against, so its natural calamity that influences more than other also will be bound to arouse fear.Be accompanied by enriching constantly of material life, people also improve gradually to the requirement of living environment.
Chinese patent 01274135 " nanometer photocatalytic air purifying sterilization machine " is to adopt the porous nano-photo catalytic film of multi-layer transparent to improve contact area, but effect and not obvious, area only can increase 1-2 doubly.
Chinese patent 02277049.6 " efficiency light catalyst air purifying device " reaches the purpose that purifies air by three metafiltration nets and photocatalyst grizzly bar.By increasing the number of plies of filter screen, though can improve the rejection rate to dust in the air effectively, this increase is extremely limited, and along with the increase of filter screen, the clarifier volume increases, and the resistance of air also increases, and energy consumption increases.
Chinese patent 02139299 " high adsorption air processor " has the fiber of high adsorption photochemical catalyst and the composite particles of active carbon and nanometer to reach clean-up effect efficiently by metal sieve plate, load.The main feature of this device is a high adsorption, but fiber is too big to the resistance of air; And ultraviolet permeability is poor, and the photocatalytic of nano-catalyst can not be given full play to, so sterilization effect is undesirable.
Three, summary of the invention
The objective of the invention is to propose a kind of air purifier and purposes with photo-catalytic nano effect at the deficiencies in the prior art, be characterized in organic functions such as filterability is strong, kill bacteria, inhibition bacteriological aftergrowth, degradation of formaldehyde, can be used for the office building, auditoriums, hotels of family, hospital, school and communal facility by having.
Purpose of the present invention is realized by following technical measures:
Air purifier with photocatalyst and nano-antibacterial effect, be characterized in that this clarifier is made up of the uviol lamp that installing band lamp socket in the printing opacity cylinder of isolating baffle plate, multi-layer fiber filter, multi-layer porous ceramic wafer, being complementary with the ceramic wafer center drilling and the printing opacity cylinder is housed in cabinet and the cabinet, by pipeline with each is installed connector and device connects and composes air purifier integral body.
Isolating baffle plate separates filter element and photocatalysis chamber, and baffle plate is connected with cabinet, only stay a side that air duct is arranged, the filter chamber is provided with the multi-layer fiber filter, multi-layer porous ceramic wafer is equipped with in the photocatalysis chamber, the porous ceramics particle of filling 20-80% between the ceramic wafer.Door is established in the cabinet front, and cabinet one side is provided with air inlet and blower fan, and the cabinet top cover is provided with the air draft plate, establishes the uviol lamp of band lamp socket in the middle of the top cover, and uviol lamp inserts in the printing opacity cylinder.Control panel is provided with power switch, transfers wind and timing knob.
The printing opacity cylinder is that good glass of ultraviolet permeability or plastics are made.
Clarifier cabinet inwall scribbles gold redrock nano-titanium dioxide.Fiber filter plate and porous ceramic plate are fiber and pottery is composited with the nano photo-catalytic material.Ceramic particle is that natural minerals diatomite, sepiolite and/or the zeolite of nano photo-catalytic material nanometer anatase titania, Nano Silver and nano zine oxide and porous is composited.The ceramic particle particle diameter is 2-20mm, porosity＞50%, specific area＞20M
2/ g, density＜1.5g/cm
3
The relative humidity of photocatalysis chamber is 95～99.5%.
Performance indications of the present invention:
1, the killing rate to common bacteria such as Escherichia coli, staphylococcus in the air reaches more than 99%.
2, to the organic degradation rates such as formaldehyde in the room air more than 99%.
Air purifier of the present invention is used for the office building, auditoriums, hotels of family, hospital, school and communal facility.
The present invention compared with prior art has following advantage:
1) contact area of air and catalyst is big: the nano compound stephanoporate ceramic particle of employing is that high-activity nano titanium dioxide, Nano Silver and nano zine oxide and porous natural minerals are composited; Particle is in suspended state in the purification process, and as the 20 square metres of calculating of specific area by 100 gram catalyst grains, every gram catalyst grains, the total contact area of air and catalyst is: 20M
2* 100=200M
2, and concerning multi-layer sheet, no matter how to increase the number of plies, several square metres only of its total contacts area.So its contact area is dozens or even hundreds of times of prior art.
2) air prolongs its time of staying in clarifier by stratum granulosum.
3) because the particle porosity height adds that particle is in suspended state, so ultraviolet light strengthens the photolytic activity increase in intergranular permeability.
4) be high humility in the catalyst chamber: from the photocatalysis principle of catalyst, under action of ultraviolet light, nano titanium oxide can have the 402.8MJ/mol reaction with the hydroxyl radical free radical HO that water forms can, be higher than all kinds of chemical bond energys in the organic compound, be the strongest in the oxidation base that exists in the water body, its energy oxidation most organic pollutants and part inorganic pollution makes it finally to be degraded to CO
2, H
2Innocuous substances such as O, and kill bacteria, virus etc.Therefore the steam in the catalyst chamber can form moisture film at particle surface, helps the carrying out of photocatalysis sterilization process.
5) the clarifier inwall is the gold redrock nano-titanium dioxide coating: because gold redrock nano-titanium dioxide has very strong covering power and anti-ultraviolet ability, therefore the clarifier inwall applies and both can prevent that ultraviolet ray from leaking behind the gold redrock nano-titanium dioxide and cause injury to the people, it is indoor simultaneously ultraviolet ray to be fixed on photocatalysis, can improve its catalytic efficiency, cut down the consumption of energy.
