Description
Technical field
The utility model belongs to air purification field, is more particularly to a kind of photoelectrocatalysis synergistic air purification device.
Background technique
Global environmental pollution and ecological disruption, has forced people to give enough concerns to environment.Wherein due to work
Atmosphere pollution caused by the discharge of industry, the vehicles etc. directly influences people's lives quality and health.Meanwhile by
The direct shadows such as the City Building syndrome caused by modern residential environment and interior decoration etc., room conditioning disease, organic contamination
It rings and arrives people's health and life security.People attempt to pass through various effective ways purifying ambient air quality.With regard to room air
For purification, the air purifier used both at home and abroad at present mainly uses active carbon adsorption technology, ozone purification technology, anion
Dedusting technology and high voltage electrostatic technique.Nuisance adsorption storage can only cannot be decomposed or be gone by active carbon adsorption technology
It removes.Once therefore adsorption saturation, needs replacing adsorbent material, and finally do not eliminate harmful substance, only by them from one
A place is transferred to another place.Since above method working principle is limited, the material for filtering absorption will be replaced often,
Otherwise it will affect the clean-up effect to air, or even secondary pollution can be generated.Ozone technology has sterilization, deodorization, but right
The removal efficiency of organic pollutant is low.More it is worth noting that, ozone of high concentration itself is harmful to human body and environment.It utilizes
Ozone technology purifies the air of a room, and people must can just enter the room after outdoor etc. is shut down every after a certain period of time.Anion and high pressure
Electrostatic technique is a kind of physical action process, can remove the flue dust in air, but to dirt caused by chemistry, biology and microorganism etc.
Dye not can be removed purification.
The developing direction that purified treatment is Current air pollution Treatment process is carried out to air using photocatalysis.Photocatalysis skill
Art has the advantage that (1) reaction condition is mild relative to other technologies such as filtering, absorption, carries out at normal temperatures and pressures；(2)
Majority of organic pollutants can be degraded to small-molecule substance.A large amount of result of study confirms that the technology can be in normal temperature and pressure item
Under part non-selectivity will difficult to degrade and toxic organic compound it is degradable be CO2And H2Inorganic pollution is aoxidized or is reduced to by O
Innocuous substance becomes in recent years the most active one of research field in the world.The basic principle of multiphase photocatalysis technology are as follows:
As semiconductor light-catalyst (such as TiO2Deng) light that is greater than forbidden bandwidth by energy irradiate when, electronics (e in valence band?)
It is excited, forbidden band of jumping over enters conduction band, and positively charged hole (h is left in valence band+).Photohole has strong oxidizing property, light
Raw electronics has strong reducing property, can the pollutant of direct oxidation and reduction adsorption on the surface, or be adsorbed on catalyst surface
On O2、OH?And H2O reacts, and generating has the active hydroxyl radical free radical of elevated chemical (OH) and H2O2, and then will have
Machine contaminant degradation, by killing bacteria.
Photocatalysis technology also has its limitation: due to electron-hole pair recombination rate height, hydroxyl radical free radical in photocatalytic process
Yield is lower, leads to that ideal removal effect can not be obtained when photochemical catalytic oxidation advanced treating organic matter.
Only inhibit the compound of electron-hole pair, photocatalysis efficiency could be improved.Countries in the world have all put into a large amount of people
Power and material resources conduct in-depth research this, and produce many outstanding research achievements.The work of forefathers is mainly from two sides
To starting with: first is that being modified from photochemical catalyst to photochemical catalyst is changed, for example, by suitably increasing photocatalyst crystals
The means such as defect, proper metal ion are adulterated, precious metal surface deposits, the coupling of two or more semiconductors can make catalyst
Itself forms effective charge carrier trap, and the separation service life of electrons and holes is made to extend part nanosecond.Second is that from outside
Condition, which is set out, changes light-catalysed condition, for example, in organic wastewater photocatalysis treatment, the use of electron capture agent can will be electric
Son and hole are completely separated, and are effective means for inhibiting electrons and holes compound；In addition, photocatalysis method is helped using electricity, in electricity
Electron-hole pair is separated by force under field action, the yield of hydroxyl radical free radical can be effectively improved.In the prior art, electricity helps light
Catalysis technique is used for the degradation treatment of organic wastewater, because electricity helps photocatalysis not only to need photocatalysis anode, photocatalysis cathode,
It also needs to immerse photocatalysis anode and photocatalysis cathode in electrolyte and just be able to achieve.Therefore, PHOTOCATALYTIC AIR-PURIFYING is being utilized
In the prior art, it yet there are no the relevant report for helping photocatalysis technology to carry out air cleaning using electricity.
Summary of the invention
The purpose of the utility model is to provide a kind of photoelectrocatalysis synergistic air purification device, which is not necessarily to
Photocatalysis anode and photocatalysis cathode immersion electrolyte can be achieved with electricity and help light-catalyzed reaction, to effectively inhibit electronics-sky
Cave pair it is compound, improve photocatalysis efficiency, the pollutant in air and bacterium can be efficiently removed, finally obtain clean sky
Gas.
