A kind of integrated combined air air purifying apparatus

Technical field

Technical field of air purification is the utility model is related to, especially a kind of integrated combined air air purifying apparatus.

Background technology

With the deterioration of air quality, haze weather phenomenon occur increasing (such as the northern area of China haze weather It is presented go out the phenomenon that increasingly aggravates), directly jeopardize the health of people, how to ensure that people can live in an air It is major issue urgently to be resolved hurrily at present in the preferable environment of quality；And capital equipment of the air purifier as purification air, Increasingly favored by people.At present, the targeted target contaminant of air purifier mainly has two classes：One kind is tool There is the particulate matter of certain particle diameter, mainly including PM10, PM2.5, pollen, airborne dust, dust etc.；Another kind of deposited with molecular size Gaseous contaminant, wherein, be most the formaldehyde distributed in finishing material or furniture by people's attention, meanwhile, also have Some gaseous inorganic oxides and the VOCs of other compositions etc..In industry, usually using to the particle using PM2.5 as representative Thing and to by the gaseous contamination that represents of formaldehyde as clean-up effect quantitative assessment is carried out to the performance of a clarifier as index.

In the prior art, mainly there are filtering type and net two kinds of the formula of electricity for the purification style that particulate matter is taken.

Wherein, filtering type is the particulate matter intercepting system formed with coarse filtration, refined filtration, ultrafiltration HEPA films etc.；And the net formula of electricity Refer to carry out absorption interception to particulate matter using electrostatic dust collection equipment.Filter screen needs generally there are using the clarifier of filtering type The defects of periodic replacement, its long-term use of cost are higher.And the clarifier of the net formula of electricity is used typically to be discharged using positive high voltage Technology and negative high voltage discharge technology, when using positive high voltage discharge technology, the operating voltage of the high voltage power supply of clarifier is general not 9KV is can exceed that, the purifying property that this is resulted in for particulate matter is not ideal enough, i.e.,：Particulate matter CADR values are not high；It is meanwhile positive high The defects of electricity also has one to become apparent is pressed to be：Caused cation can overflow with the circulation of air in positive high voltage electric discharge Go out, and the cation overflowed has harm to the health of human body.Compared with the clarifier of positive high voltage electric discharge, negative high voltage electric discharge During although clarifier is not in drawbacks described above, but negative high voltage discharges, its ozone output can be more smelly than what positive high voltage discharged Oxygen yield is much higher, and ozone content is too high still to damage to the health of human body.

Plasma for purification formula clarifier can simultaneously particulate matter and gaseous contaminant, the purification to particulate matter is wide Well known electrostatic precipitator technology, and the purification to gaseous contaminant mainly for target contaminant be VOCs, it purifies former Reason is exactly substantially catalytic purification, is on the one hand during plasma is produced, electrion produces moment high-energy, beats The chemical bond of some pernicious gas molecules is opened, it is resolved into harmless molecule；On the other hand it is comprising substantial amounts of in plasma High energy electron, ion, excited state particle and the free radical isoreactivity ion with strong oxidizing property, the average energy of these active ions Amount is above the bond energy of gas molecule, when they and pernicious gas molecule collide, can open the chemical bond of gas molecule, together When can also produce substantial amounts of OH, HO₂, the free radical such as O and the extremely strong ozone of oxidisability, these oxidizing substances with it is harmful Chemical reaction occurs for gas molecule so as to generate harmless products.

Photocatalysis formula clarifier is then to trigger and promote photocatalysis oxidation reaction by light irradiation photochemical catalyst, is realized organic The decomposition of thing, it mainly includes four courses of reaction：First, the generation in photoinduced electron and hole；2nd, O₂、H₂O and organic matter are being urged Agent surface attachment；3rd, the generation of oxidant；4th, the catalytic decomposition of organic matter.Must be in light on general such air purifier The leading portion configuration particulate matter of catalytic process intercepts filter screen, in case light source or photocatalyst surface by Particulate Pollution, cause light to be urged Change failure.
