1、“HEPA高效過濾技術(shù)”濾凈效能好
HEPA是一種國際公認(rèn)最好的高效濾材,HEPA過濾器由一疊連續(xù)前后折疊的亞玻璃纖維膜構(gòu)成(空氣凈化機(jī)中常用PP,聚丙烯材質(zhì)),形成波浪狀墊片用來放置和支撐過濾界質(zhì)。HEPA高效率微粒濾網(wǎng)的濾凈效能與其表面積成正比。目前HEPA空氣凈化裝置的HEPA高效率微粒濾網(wǎng)均是多層折疊,展開后面積比折疊時(shí)增加十幾倍到幾十倍,濾凈效能十分出眾。
HEPA is an internationally recognized best high efficiency filter material, HEPA filter is composed of a stack of continuous before and after folding sub-glass fiber membrane (commonly used in air purifier PP, polypropylene material), the formation of a wavy gasket used to place and support the filtration boundary material.The filter efficiency of HEPA particulate filter is proportional to its surface area.At present, HEPA air purification device HEPA high efficiency particulate filter is multi-layer folding, after the expansion of the area than folding increased by ten times to dozens of times, filtration efficiency is very outstanding.
凈化原理:微粒慣性原理和擴(kuò)散原理。
Purification principle: particle inertia principle and diffusion principle.
HEPA凈化技術(shù)優(yōu)點(diǎn):
過濾顆粒物的效果非常明顯!對(duì)微粒的捕捉能力較強(qiáng),孔徑微小,吸附容量大,凈化效率高,并具備吸水性,針對(duì)0.3微米的粒子凈化率為99.97%。如果用它過濾香煙煙霧,那么過濾的效果幾乎可以達(dá)到100%。2.5μm以上的顆粒,僅需F8的就可以過濾效果達(dá)到99%以上了。
The effect of filtering particulate matter is very obvious!It has strong ability to capture particles, small pore size, large adsorption capacity, high purification efficiency, and has water absorption, and the purification rate for 0.3 micron particles is 99.97%.If it is used to filter cigarette smoke, it is almost 100% effective.For particles above 2.5μm, only F8 can filter more than 99%.
HEPA凈化技術(shù)缺點(diǎn):
我國塵土比較嚴(yán)重,HEPA的使用壽命可能相對(duì)縮短,也就意味著HEPA過濾器需要經(jīng)常更換以及使用成本高。目前,空氣凈化行業(yè)中的風(fēng)速普遍不是在HEPA的合適風(fēng)速下工作,潔凈室這類要求高的場(chǎng)所保證HEPA的凈化效率在0.3-0.5m/s左右,實(shí)際使用中的風(fēng)速都是遠(yuǎn)高于這個(gè)值。
China's dust is more serious, the service life of HEPA may be relatively shortened, which means that HEPA filters need to be replaced often and the use of high cost.At present, the wind speed in the air purification industry is generally not the right wind speed in the work of HEPA, clean room such high requirements of the place to ensure that the purification efficiency of HEPA in 0.3-0.5m/s, the actual use of wind speed is much higher than this value.
2、“靜電集塵技術(shù)”,無耗材除塵
靜電集塵技術(shù)是利用高壓靜電吸附的原理,將空氣中的污染物過濾,同樣作為基礎(chǔ)凈化技術(shù),被廣泛應(yīng)用于室內(nèi)空氣凈化器上。
Electrostatic dust collection technology is the use of high voltage electrostatic adsorption principle, the air pollutants in the filter, also as a basic purification technology, is widely used in indoor air purifiers.
凈化原理:高壓強(qiáng)電場(chǎng)的作用,顆粒物吸附在負(fù)極板或者正極板,異種電荷相互吸引。
Purification principle: the effect of high voltage and strong electric field, particles adsorbed on the negative plate or positive plate, dissimilar charges attract each other.
靜電集塵技術(shù)優(yōu)點(diǎn):
高效去除空氣中的微粒污染物,如灰塵、煤煙、花粉、香煙味和廚房油煙等,同時(shí)還可有效吸附空氣中的氣態(tài)污染物及濾除空氣中的致病微小生物,無耗材,清洗可重復(fù)使用,真正的環(huán)保;
Efficient removal of particulate pollutants in the air, such as dust, soot, pollen, cigarette smell and kitchen lampblack, but also can effectively adsorb gaseous pollutants in the air and filter out pathogenic small organisms in the air, no supplies, cleaning can be reused, real environmental protection;
靜電集塵技術(shù)缺點(diǎn):
容易產(chǎn)生臭氧,而且只對(duì)顆粒物等大粒子氣體有效果,主要用于除塵,而對(duì)于去除甲醛、苯系物、TVOC等裝飾裝修造成的化學(xué)污染幾乎沒有效果,相當(dāng)于初中效過濾網(wǎng),凈化本質(zhì),還屬于物理凈化,有害物質(zhì)并沒有被化學(xué)分解。
It is easy to produce ozone, and only has an effect on large particle gases such as particulate matter, which is mainly used for dust removal. It has almost no effect on the removal of chemical pollution caused by formaldehyde, benzene series, TVOC and other decoration. It is equivalent to the filter screen of junior high school effect, which is purification essence, and also belongs to physical purification, and harmful substances are not decomposed chemically.
3、“活性炭吸附技術(shù)”,吸附能力很強(qiáng)
活性炭分為椰殼類、果殼類和煤炭類三種,吸附能力以椰殼類活性炭最強(qiáng)。
Activated carbon is divided into coconut shell, nut shell and coal three kinds, the adsorption capacity of coconut shell activated carbon is the strongest.
凈化原理:活性炭多孔結(jié)構(gòu),比表面積大,能吸附小顆粒物質(zhì)。
Purification principle: activated carbon porous structure, large specific surface area, can absorb small particles
活性炭優(yōu)點(diǎn):對(duì)所有的空氣污染物都具有凈化作用。吸附能力很強(qiáng),能夠有效吸附室內(nèi)空氣中的有害物質(zhì)(諸如粉塵、微粒、游離分子、細(xì)菌等)。
Advantages of activated carbon: all air pollutants have a purification effect.Strong adsorption capacity, can effectively absorb harmful substances in indoor air (such as dust, particles, free molecules, bacteria, etc.).
活性炭缺點(diǎn):活性炭只是屬于物理過濾,污染物并沒有被消除,只能暫時(shí)吸附,并且隨溫度、風(fēng)速升高,所吸附的污染物就有可能游離出來,所以要經(jīng)常更換過濾材料,避免吸附飽和。
Activated carbon disadvantages: activated carbon is just a physical filtration, pollutants have not been eliminated, can only be temporarily adsorbed, and with the temperature, wind speed rise, the adsorption of pollutants may be free, so often replace the filter material, avoid adsorption saturation.
4、負(fù)離子技術(shù),煙霧沉降、補(bǔ)充“空氣維生素”
通過負(fù)離子發(fā)生器,產(chǎn)生大量的負(fù)離子,也叫負(fù)氧離子,具有鎮(zhèn)靜、催眠、鎮(zhèn)痛、增食欲、降血壓等功能。雷雨過后,人們感到心情舒暢,就是空氣的負(fù)離子增多的緣故??諝庳?fù)離子能還原來自大氣的污染物質(zhì)、氮氧化物、香煙等產(chǎn)生的活性氧(氧自由基)、減少過多活性氧對(duì)人體的危害;中和帶正電的空氣飄塵無電荷后沉降,使空氣得到凈化。
Through the negative ion generator, produce a large number of negative ions, also called negative oxygen ions, with sedation, hypnosis, analgesia, appetite, drop blood pressure and other functions.The increase in negative ions in the air is the reason why people feel good after a thunderstorm.Air anion can reduce the reactive oxygen species (oxygen free radicals) produced by pollutants from the atmosphere, nitrogen oxides and cigarettes, and reduce the harm of excessive reactive oxygen species to human body.Neutralize positively charged air drift dust without charge after settling, so that the air is purified.
凈化原理:正負(fù)電荷中和,以及負(fù)離子的還原作用。
Purification principle: positive and negative charge neutralization, as well as reduction of negative ions.
負(fù)離子優(yōu)點(diǎn):
對(duì)二手煙等顆粒物沉降作用明顯,因此一程度上能除煙味,主要是因?yàn)榭諝庵械臒熿F顆粒物減少,煙味的顆粒物沉降到地面,更多的是屬于物理凈化。對(duì)人體有抗氧化、抗衰來、增強(qiáng)人體免疫力、增強(qiáng)自愈能力的作用,能有效增強(qiáng)血液攜氧能力20%左右并有效促進(jìn)人體新陳代謝改善睡眠,對(duì)殺菌有一定的作用。
The sedimentation effect of second-hand smoke and other particles is obvious, so to some extent, it can remove the smell of smoke, mainly because the smoke particles in the air are reduced, the smoke particles settle to the ground, more belongs to the physical purification.It has the function of anti-oxidation, anti-aging, enhancing human immunity and self-healing ability. It can effectively enhance the oxygen carrying capacity of blood by about 20% and effectively promote human metabolism and improve sleep. It has a certain effect on sterilization.
負(fù)離子缺點(diǎn):
負(fù)氧離子起凈化作用過程中主要是“物理凈化”,空氣中的污染物被轉(zhuǎn)移到地上了;負(fù)氧離子在空氣中壽命很短,所以需要持續(xù)釋放;對(duì)因裝飾裝修造成的甲醛苯系物等污染凈化效果則很一般,所以需要您區(qū)別選擇。
Negative oxygen ions play a role in the process of purification is mainly "physical purification", the pollutants in the air are transferred to the ground;Negative oxygen ions have a short life in the air, so they need to be released continuously.For the decoration caused by formaldehyde benzene series pollution purification effect is very general, so you need to choose.
5、臭氧,殺菌除味迅速徹底
活性氧技術(shù)是基于臭氧發(fā)生器的應(yīng)用,也是種基礎(chǔ)凈化技術(shù),凡是離子發(fā)生器基本都能釋放出一定濃度的臭氧,也被廣泛應(yīng)用于絕大多數(shù)的空氣凈化器中。
Reactive oxygen technology is based on the application of ozone generator, is also a basic purification technology, all ion generator can release a certain concentration of ozone, is also widely used in the vast majority of air purifiers.
在使用臭氧殺菌的凈化器時(shí),務(wù)必要嚴(yán)格注意臭氧的產(chǎn)生率是否符合國家標(biāo)準(zhǔn)(國家衛(wèi)生部規(guī)定的臭氧安全濃度為0.1ppm,工業(yè)衛(wèi)生標(biāo)準(zhǔn)為0.15ppm),同時(shí)使用臭氧發(fā)生器凈化室內(nèi)空氣時(shí)人員必須離開,消毒完畢開窗通風(fēng)半小時(shí)以上。
In the use of ozone sterilization of the purifier, be sure to pay strict attention to the ozone production rate is in line with the national standard (the Ministry of Health prescribed ozone safety concentration of 0.1ppm, industrial hygiene standards for 0.15ppm), at the same time the use of ozone generator to purify indoor air personnel must leave, disinfection completed more than half an hour window ventilation.
凈化原理:臭氧的強(qiáng)氧化性,可以氧化有機(jī)物、臭味分子,氧化微生物的功能結(jié)構(gòu)使失活。
Purification principle: strong oxidation of ozone, can oxidize organic matter, odor molecules, oxidize the functional structure of microorganisms so that inactivation.
臭氧凈化的優(yōu)點(diǎn):
臭氧對(duì)細(xì)菌的滅活反應(yīng)很迅速、殺菌的徹底性也是不容懷疑的,合理使用時(shí)是國際公認(rèn)的最環(huán)保最徹底有效的凈化方式。當(dāng)其濃度達(dá)到一定值后,殺菌消毒甚至可以瞬間完成。
Ozone on the bacterial inactivation reaction is very rapid, sterilization thornness is not doubt, reasonable use is the international recognized the most environmental protection and the most thorough and effective way of purification.When its concentration reaches a certain value, sterilization can even be completed instantly.
臭氧凈化的缺點(diǎn):
超標(biāo)的臭氧對(duì)人體健康有嚴(yán)重危害!高濃度的臭氧,會(huì)造成咽喉腫痛、胸悶咳嗽、引發(fā)支氣管炎和肺氣腫、造成神經(jīng)中毒、破壞人體的免疫機(jī)能等。由于臭氧有強(qiáng)烈刺激性,人們?cè)诟械讲贿m時(shí)早已避開,因此在使用過程中一般不會(huì)出現(xiàn)中毒現(xiàn)象。
Excessive ozone is a serious hazard to human health!High concentration of ozone, will cause sore throat, chest tightness cough, cause bronchitis and emphysema, cause nerve poisoning, destroy the immune function of the human body.Because ozone has strong irritation, people have long avoided when they feel uncomfortable, so in the process of use generally will not appear toxic phenomenon.
6、“光觸媒催化分解技術(shù)”有紫外線才能發(fā)揮作用
光催化技術(shù),是一種利用新型的復(fù)合納米高科技功能材料的技術(shù),就是指光催化反應(yīng)。
Photocatalytic technology, is a use of new composite nanometer high-tech functional materials technology, refers to the photocatalytic reaction.
光催化凈化原理:在光源照射下,光觸媒能夠利用特定波長光源的能量產(chǎn)生催化作用(氧化還原反應(yīng)),使周圍的氧氣及水分子激發(fā)成具高活性的自由基,這些自由基,也有說法叫“光等離子體”,幾乎可分解所有對(duì)人體或環(huán)境有害的有機(jī)物質(zhì)及部分無機(jī)物質(zhì)。(光觸媒(Photocatalyst),也稱為光催化劑(Light catalyst),是一類以二氧化鈦(TiO2)為代表的,在光的照射下自身不起變化,卻可以促進(jìn)化學(xué)反應(yīng),具有催化功能的半導(dǎo)體材料的總稱。)
Photocatalytic purification principle: under the light irradiation, the light catalyst catalyzed to be able use energy from the specific wavelength light source (REDOX reaction), the surrounding of inspired oxygen and water molecules into a highly reactive free radicals, these free radicals, also have is called "plasma" light, almost all or harmful to the environment to the human body can be decomposed organic material and part of inorganic substances.Photocatalyst, also known as Light catalyst, is a kind of titanium dioxide (TiO2) as a representative, under the irradiation of Light itself can not change, but can promote chemical reaction, has the catalytic function of semiconductor materials.
光催化優(yōu)點(diǎn):光催化技術(shù)具有廣譜性的實(shí)用性效果,凈化效率較高。
Photocatalytic advantages: Photocatalytic technology has a wide spectrum of practical effect, high purification efficiency.
光催化缺點(diǎn):光觸媒必須在紫外線的照射下才能發(fā)揮作用。這意味著,一是必須另外加上紫外燈發(fā)射紫外線(波長在254nm或者365nm),但是過多的紫外線對(duì)人體有傷害,所以要避免紫外線燈裸露;二是,光觸媒必須能和紫外線接觸,所以顆粒物多的環(huán)境,光觸媒是會(huì)“冬眠”的。
Disadvantages of photocatalysis: photocatalyst must be in the ultraviolet radiation to play a role.This means that, first, the ultraviolet lamp must be added to emit ultraviolet radiation (wavelength in 254nm or 365nm), but too much ultraviolet radiation is harmful to the human body, so the ultraviolet lamp should be avoided;Second, the photocatalyst must be able to contact with ultraviolet light, so the environment with more particles, the photocatalyst will "hibernate".
7、“分子絡(luò)合技術(shù)”治理室內(nèi)裝修污染效果明顯
分子絡(luò)合技術(shù)是目前能夠真正有效徹底去除室內(nèi)裝修污染,尤其是化學(xué)污染的技術(shù)。該技術(shù)首先對(duì)室內(nèi)裝修污染甲醛、苯、氨等污染物進(jìn)行收集、捕捉,再通過甲醛捕捉劑和水組成的絡(luò)合分解體系,分別將甲醛和氨等氣態(tài)短分子鏈物質(zhì),迅速絡(luò)合轉(zhuǎn)化為不可逆的長分子鏈固態(tài)物質(zhì),并分解生成氨鹽,結(jié)聚、沉淀于水中清除分離,排放出清潔空氣。

Solution containing complex ions or similar components, need to be replaced regularly, especially in the new residence when the degree of pollution is high replacement frequency.Produce new solution, direct discharge of secondary pollution to the environment;
8、“低溫非對(duì)稱等離子體空氣凈化技術(shù)”超節(jié)能、超環(huán)保
低溫非對(duì)稱等離子體空氣凈化技術(shù),目前主要通過介質(zhì)阻擋放電實(shí)現(xiàn),即DBD低溫等離子,現(xiàn)在主要存在2中,一種是正高負(fù)低的DBD低溫等離子,凈化能力強(qiáng),主要用在工業(yè)凈化和無人環(huán)境凈化;另一種是負(fù)高正低的DBD低溫等離子,簡(jiǎn)稱NBD等離子(negative ion high DBD),主要應(yīng)用在人居環(huán)境,人機(jī)共存環(huán)境。
Low-temperature asymmetric plasma air purification technology is mainly realized through dielectric barrier discharge, that is, DBD low temperature plasma. Now there are mainly 2. One is positive high negative low DBD low temperature plasma, which has strong purification ability and is mainly used in industrial purification and unmanned environment purification.The other is the negative ion high DBD low temperature plasma, referred to as NBD plasma (negative ion high DBD), mainly used in human living environment, human-machine coexistence environment.
凈化原理:低溫非對(duì)稱等離子體空氣凈化技術(shù)能使空氣中大量等離子體之間逐級(jí)撞擊,產(chǎn)生電化學(xué)反應(yīng),對(duì)有毒有害氣體及活體病毒、細(xì)菌等進(jìn)行快速降解,從而高效殺毒、滅菌、去異味、消煙、除塵,且無毒害物質(zhì)產(chǎn)生

低溫等離子優(yōu)點(diǎn):
該技術(shù)在凈化室內(nèi)空氣時(shí),可人機(jī)共存,同比可以節(jié)約80%的電能,又終身免拆洗。具有快速消殺病毒、超強(qiáng)凈化能力、高效祛除異味、消除靜電功能、增加氧氣含量等特點(diǎn)。

低溫等離子缺點(diǎn):
作為尚未普及一項(xiàng)新技術(shù),目前技術(shù)成熟的廠家并不多,基于該技術(shù)的產(chǎn)品不多,并且存在價(jià)格上的不透明。德國碧歐、韓國SP、美國BOX,國內(nèi)浙江、福建也有幾家很不錯(cuò)。
As a new technology that has not yet been popularized, there are not many manufacturers with mature technology at present. There are not many products based on this technology, and the price is not transparent.Germany, SP, South Korea, the United States BOX, Zhejiang, Fujian also have several very good.
此處的低溫等離子,指負(fù)高正低的低溫等離子,即NBD類型。
簡(jiǎn)要總結(jié):
通過一種空氣凈化技術(shù)就可以完美地解決所有空氣污染的問題,目前是不存在的,面對(duì)不同的污染源我們需要選擇最適合的空氣凈化技術(shù)產(chǎn)品,同時(shí)也要結(jié)合自己的實(shí)際情況選擇合適的產(chǎn)品。最好是選擇CCM值比較高的凈化機(jī),這樣產(chǎn)生的耗材小,對(duì)環(huán)境污染比較小。
