跟著大家對室內(nèi)空氣質(zhì)量重要性知道的進步,空氣過濾已成為許多家庭的需求,包含運用于居處的供暖與通風(fēng)空調(diào)體系(HVAC)、便攜式空氣凈化器和真空吸塵器,因而空氣過濾的發(fā)展趨勢是供給更優(yōu)秀的過濾功能和更長運用周期的更領(lǐng)先的過濾體系。在這些運用中,各種過濾體系運用了不一樣技能和規(guī)模廣泛的過濾介質(zhì)。一臺專有過濾設(shè)備下降顆粒物濃度的功率是設(shè)備的過濾功率及其空氣處理量的函數(shù)。
As you know the importance of progress on indoor air quality, air filtration has become a lot of family needs, including heating and ventilation and air conditioning used in home system (HVAC), portable air purifier and vacuum cleaner, and development trend of air filter is for better filtering function and longer cycle by using more advanced filtration system. In these applications, various filtering systems employ different skills and a wide range of filtering media. The power of a proprietary filtration equipment to decrease particle concentration is a function of the equipment's filtration power and its air handling capacity.
這篇文章論說的是最新的關(guān)于商用和居處HVAC、便攜式空氣凈化器和真空吸塵器的過濾介質(zhì)立異技能。由于這些運用,使過濾介質(zhì)具有卓越功能的技能取得了突破性的進展。運用該過濾介質(zhì)技能可到達最小過濾值(MERV)16級過濾水平而壓下降于MERV10過濾器。與別的商品過濾器比較,由功能優(yōu)秀的介質(zhì)制成的便攜式空氣凈化器可使高效空氣過濾(HEPA)的潔凈空氣輸出率(CADR)進步10%～30%;真空吸塵器運用由新研發(fā)的過濾介質(zhì)制成的過濾器,其功能有極大的進步。

空氣中的顆粒物與空氣凈化.有確切的科學(xué)數(shù)據(jù)標(biāo)明,高度污染的環(huán)境可嚴(yán)重危害公眾健康。最新的研討顯現(xiàn)顆粒物濃度與死亡率成正比,在顆粒物濃度較高的城市中日子的人比在顆粒物濃度較低的城市中日子的人壽命短。死亡率與細(xì)微顆粒物的濃度有關(guān)。呈現(xiàn)明顯的環(huán)境空氣污染,特別是在許多市區(qū)內(nèi)呈現(xiàn)煙霧,致使大家認(rèn)為室內(nèi)的空氣比周圍的空氣潔凈。但是很多的研討標(biāo)明,室內(nèi)某些空氣污染物的濃度大于室外。依據(jù)近來20年以來的科學(xué)研討,室內(nèi)空氣質(zhì)量對人類健康疑問有嚴(yán)重的影響,如發(fā)作頭疼、厭惡、呼吸體系感染病和別的病癥。考慮到大多數(shù)人,特別是嬰兒和老年人,在戶內(nèi)(或在家、校園或在作業(yè)場合)的時刻達80%～90%,健康疑問起因于室內(nèi)污染物的可能性添加。由于每個人天天吸入10～20m3的空氣,呼吸體系是生物氣溶膠和別的顆粒物質(zhì)的首要進進口和堆積處。
Particulate matter in the air and air purification. Exact scientific data indicate that highly polluting environments can seriously endanger public health. Recent studies show that particle concentration is directly proportional to mortality, and in cities with higher concentrations of particulates, people live shorter days than those in cities with lower concentrations of particulates. The mortality rate is related to the concentration of fine particles. Air pollution is obvious, especially in many urban areas, which results in the fact that indoor air is cleaner than the surrounding air. But many studies show that indoor air pollutants are more dense than outdoors. According to recent 20 years of scientific research, indoor air quality has a serious impact on human health problems, such as headache, aversion, respiratory infections and other diseases. In view of the fact that most people, especially infants and the elderly, have 80% to 90% hours indoors (or at home, on campus or at work), health problems arise from the possibility of indoor pollutants. As each person inhaled 10 to 20m3 of air every day, the respiratory system is the primary inlet and accumulation of aerosols and other particulate matter.
室內(nèi)空氣污染物是空氣中的有害物質(zhì),其規(guī)模從顆粒物到有機/無機化合物和氡氣,這篇文章內(nèi)容僅觸及榜首部分:顆粒物(包含生物氣溶膠)。顆粒物是被用來描繪非常小的固體或液體顆粒的專門名詞,其顆粒尺度約0.005～500μm。各個顆粒在巨細(xì)、化學(xué)組分和物理功能上都能夠各不相同。大氣氣溶膠濃度和室內(nèi)顆粒物濃度密切有關(guān)。根據(jù)這一研討,能夠得出室內(nèi)空氣比室外空氣有更高顆粒物濃度的定論。大家活動在空氣相對密閉的大廈內(nèi)將增大濃度的差別。大家發(fā)現(xiàn),室內(nèi)和室外顆粒物巨細(xì)分布類似,但室內(nèi)亞微米級顆粒物的份額更大。室內(nèi)顆粒物可由室外空氣、抽煙、火爐、壁爐、居住者的活動、地毯、帷幕和寵物等而引入。
Indoor air pollutants are hazardous substances in air, ranging in size from particulate matter to organic / inorganic compounds and radon gas. This article touches only the first part: particulate matter (including biological aerosols). Particles are special terms used to describe very small solid or liquid particles whose particle sizes range from about 0.005 to 500 m. Each particle is different in size, chemical composition, and physical function. Atmospheric aerosol concentration is closely related to indoor particulate matter concentration. According to this study, it can be concluded that indoor air has higher particle concentration than outdoor air. Everyone will be in the air relatively airtight building will increase the difference in concentration. It is found that indoor and outdoor particles are similar in size and distribution, but the share of submicron particles in the interior is greater. Indoor particulates can be introduced by outdoor air, smoking, stoves, fireplaces, occupants' activities, carpets, curtains and pets.
關(guān)于有吸煙者的居處,室內(nèi)/室外可吸入的顆粒物濃度比規(guī)模為1.1～4.4。很明白,吸煙者是室內(nèi)顆粒物的首要制造者,而別的室內(nèi)顆粒物來歷,例如烹諧和打掃衛(wèi)生,對室內(nèi)/室外顆粒物濃度比的影響大不相同。室內(nèi)污染源甚至在無煙的家庭里也可能使PM2.5的濃度(顆粒物空氣動力學(xué)直徑<2.5μm)進步,由10μg/m3到每立方米數(shù)百微克。在本項研討中平均室內(nèi)顆粒物濃度是PM2.5=11.8μg/m3,且稍高于室外濃度;而室內(nèi)有機碳均勻含量大大高于室外濃度,分別為7.8和3.0μg/m3,這意味著室內(nèi)活動或許對室內(nèi)有機碳的含量有嚴(yán)重影響。在同一項研討中,研討了室內(nèi)和室外PM2.5相對毒性,發(fā)現(xiàn)室內(nèi)吸收毒素均勻含量為3.3EU/mg,高于室外含量2.0EU/mg。
A smoker's abode, indoor / outdoor respirable particulate concentration than the scale of 1.1 ~ 4.4. It is clear that smokers are the primary producers of indoor particulates, while other indoor sources of particulate matter, such as cooking, coordination and cleaning, have very different effects on indoor / outdoor particle concentration ratios. Indoor sources of pollution, even in smoke-free homes, may also improve PM2.5 concentrations (particulate matter, aerodynamic diameter, <2.5, m), ranging from 10 g/m3 to hundreds of micrograms per cubic meter. In this study the average indoor particle concentration is PM2.5=11.8 g/m3, and slightly higher than the outdoor and indoor uniform concentration; organic carbon content is much higher than outdoor concentrations were 7.8 and 3 g/m3, which means that the content of indoor activities may have serious impact on indoor organic carbon. In the same study, the relative toxicity of indoor and outdoor PM2.5 was studied. It was found that the content of indoor absorbed toxin was 3.3EU/mg, which was higher than that of outdoor 2.0EU/mg.
由于室內(nèi)活動和從外部環(huán)境的進入,通常顆粒巨細(xì)在0.01～20μm之間改變,空氣清潔設(shè)備能削減該尺度規(guī)模內(nèi)的顆粒物濃度;而亞微米級顆粒的鏟除是非常關(guān)鍵的,由于更小的顆粒物能被吸入到呼吸道的深處并在肺泡區(qū)占據(jù)數(shù)年,或許可溶解顆粒會被吸收而進入血液。
As the indoor activities and from entering into the external environment, usually the particle size changes between 0.01 ~ 20 m, air cleaning equipment can reduce the scale of particle concentration; and the eradication of sub micron particles is very important, because the particles can be inhaled into smaller suction way and in the depths of the call the alveolar zones occupy a number of years, or permission of dissolved solids will be absorbed into the blood.
室內(nèi)空氣污染對公共衛(wèi)生晦氣影響的最新知道推動了對高功能空氣凈化商品繼續(xù)不斷的需求。現(xiàn)在用戶請求商品在相同的空氣流速下進步過濾功率、削減運用周期費用、體積更小和功能牢靠。
The latest knowledge of the adverse effects of indoor air pollution on public health has prompted continued demand for highly functioning air cleaning products. Now, the user requests the product to increase filtering power at the same air flow rate, reduce the use cycle cost, smaller size and reliable function.
商用和居處HVAC體系廣泛地運用空氣過濾器來維護居住者和設(shè)備免受空氣的顆粒物侵蝕,需求有更高的過濾功率,特別是過濾亞微米級顆粒物。典型的MERV15～16過濾器在空氣外表速度2.5m/s下操作時,初始壓降大于150Pa,致使運用時期的高能耗本錢,約占設(shè)備總本錢的80%,不可能到達運用周期本錢(LCC)的請求。為了削減運用周期本錢,開發(fā)了壓降明顯下降的過濾器。
Commercial and home HVAC system widely used air filter to maintain the occupants and equipment from particulate air filtration erosion, demand higher power, especially the sub micron particle filter. Typical MERV15 ~ 16 filter operation in the air surface speed 2.5m/s, initial pressure drop is greater than 150Pa, resulting in the use of the period of high energy consumption costs, accounting for about 80% of the total cost of the equipment, may not reach the use cycle cost (LCC) request. To reduce cycle cost, a filter with a significant drop in pressure has been developed.
用于機械式空氣凈化器的褶型過濾器通常是由玻璃纖維或駐極改性的合成過濾介質(zhì)制成,過濾功率可到達HEPA級?？諝鈨艋鞯墓δ苡肅ADR表述,能夠經(jīng)過運用低壓降和堅持相同功率的過濾器而使CADR明顯進步。
A pleated filter used in a mechanical air purifier, usually made of fiberglass or electret modified synthetic filter media, with filtration power of HEPA. The function of the air purifier is expressed in CADR, which can make CADR obvious progress after using low voltage drop and adhering to the same power filter.
上述情況與可重復(fù)運用的非袋式、借助于離心力從氣流中除掉部分塵粒的旋轉(zhuǎn)式真空除塵器類似。用過濾功率和除塵性質(zhì)類似但壓力較低的過濾介質(zhì)代替ePTFE薄膜制成濾筒式過濾器的打褶濾筒時,真空除塵器的功能也能得以改進。
The above is similar to a rotary vacuum cleaner which can be reused in a non bag type and with the aid of centrifugal force to remove some of the dust particles from the air stream. The vacuum cleaner can be improved by using a filter medium with a similar filter power and a low pressure, instead of a ePTFE film, which is made into a pleated cartridge for a cartridge filter.
