Definitions

  • the present invention relates to an air sterilization device having a hydroxyl radical generating device, and in more detail, to an air sterilization device having an optimal condition for generating hydroxyl radical ( ⁇ OH) and thereby generating a maximum hydroxyl radical per unit time
  • ⁇ OH hydroxyl radical
  • This is an air sterilization device that can effectively remove carbon monoxide, sulfur dioxide, nitrogen dioxide and other air pollutants or bacteria that are pollutants in the air.
  • the device used to satisfy this desire is an air purifier or an air sterilization device.
  • Contaminated air contains volatile organic compounds, and mold (ultrafine bacteria) is attached to the volatile organic compounds.
  • Bacteria as single-celled organisms, usually inhabit humid environments. If people inhale air contaminated by volatile organic compounds and spores generated from bacteria and mold, it will become the root cause of various diseases. Bacteria and mildew will cause allergies and cause systemic infections. The cell walls of bacteria and mildew protect against physical-chemical external attacks.
  • Mite dust has been the subject of research in the field of biology for centuries. So far, more than 30,000 species have been identified.
  • hydroxyl free radical hydroxyl free
  • the base is the main cleansing agent in the atmosphere that eliminates various pollutants such as carbon monoxide, sulfur dioxide, and nitrogen dioxide. Hydroxyl radicals in nature exist in the air at a density of 2 to 20 million (per 1cc air, per second basis).
  • the first way is to suck in the air in the purification target space to make it pass through the filter and absorb or decompose the pollutants in the air through the filter. This is the most commonly used method. In the case of using this method for a long time, it is necessary to replace it with a new filter regularly. This kind of maintenance management is necessary, but because the characteristics of the filter are not perfect, the reliability of the air purification capacity in this way Not high.
  • the second method is to increase the ion concentration in the air by using an ion generating device.
  • the current air purifiers that use this method only generate negative ions. Although the effects of purification and sterilization by negative ions can reach a certain level, they are not accurate. Mastering the amount of negative ion emissions is not only that, but the effect associated with the strong removal of planktonic bacteria in the air is not high.
  • the third way is to use plasma cluster ion (Plasma Cluster Ion, PCI) technology.
  • plasma ion air purification technology using plasma charge will be used, that is, by discharging negative ions and positive ions into the air And through the chemical reaction with the harmful substances in the air to decompose the harmful substances or inactivate the harmful substances, thereby purifying the air.
  • the present invention provides the most effective removal of carbon monoxide, sulfur dioxide, nitrogen dioxide, etc., which are pollutants in the air, by realizing the formation structure with the best conditions for generating hydroxyl radicals and thereby generating the largest hydroxyl radicals per unit time
  • An air sterilization device for air pollutants or bacteria for air pollutants or bacteria.
  • An air sterilization device includes: an outer cover formed with an air flow path; an ozone generating portion that generates ozone particles to supply to the air flow path; and a filter cartridge that receives ozone generated by the ozone generating portion to discharge the contained ozone And hydroxyl radical bubbles; an ultrasonic generating section connected to the filter cartridge to generate ultrasonic waves; a blower fan for supplying air to the air flow path of the housing; and a power supply section for supplying the ozone generating section , The power of the ultrasonic generator and the fan.
  • the cover includes: a first flow path for guiding air supplied from the above-mentioned blower fan; a second flow path for guiding gas in bubbles generated by the solution in the filter cartridge; and a third flow path such that the first flow path The air flowing in and the gas in the second flow path are mixed.
  • An air sterilization device further includes: a photocatalytic substance coated on at least one of the second flow path and the third flow path; and a light source configured on the second flow path to irradiate the photocatalytic substance below 390 nm Of ultraviolet light.
  • An air sterilization device further includes a pump connected to the ozone generating unit to supply a part of ozone to the filter cartridge.
  • the pump only works for a part of the time during the operation of the ozone generating part, that is, only 5 minutes to 10 minutes per hour.
  • a filter cartridge of an air sterilization device includes: a tank for accommodating a solution; a diffusion tube connected to a pump to supply ozone into the solution; and an evaporation portion that absorbs the solution and vaporizes the solution.
  • the filter cartridge of the air sterilization device includes: a first tank for containing a solution; a second tank; a diffusion tube connected to the pump to supply ozone to the lower part of the first tank; The upper part of one tank is connected to the lower part of the second tank to supply the gas in the solution of the first tank to the second tank; and the evaporation part absorbs the solution of the second tank to vaporize the solution.

Description

空气杀菌装置 技术领域
本发明涉及具有羟基自由基产生装置的空气杀菌装置，更详细地，涉及通过实现具有产生羟基自由基(·OH)的最佳条件的空气杀菌装置并由此在单位时间内产生最大羟基自由基来最有效地去除作为空气中的污染物质的一氧化碳、二氧化硫、二氧化氮等各种空气污染物质或细菌的空气杀菌装置。
背景技术
随着工业化的发展及城市化、人口集中现象加剧，人类每天呼吸所需的空气的污染问题日趋严重。人类每天使用的化石燃料必然向空气排出对人类有害的污染物质，病毒或细菌等的病原性微细物质等在空气中的浓度也变高，导致人们想呼吸清洁空气的愿望越发强烈。为了满足这种欲望而使用的装置为空气净化器或空气杀菌装置。
受污染的空气中包含挥发性有机化合物，而且在这种挥发性有机化合物附着有霉(超微细细菌类)，细菌作为单细胞生物，通常栖息在潮湿的环境中。若人吸入因从细菌和霉产生的挥发性有机化合物和孢子而受到污染的空气，则将成为各种疾病的根源。细菌和霉将引发过敏并引起系统性的感染。细菌和霉的细胞壁起到避免受到物理-化学性的外部攻击的作用。
霉或酵母对Gram氏阳性细菌和Gram氏阴性细菌之间的杀菌混合物具有抵抗力。同样，具有甲壳质的外部骨骼的螨虫类通过栖息在受污染的环境来成为室内微尘，从而对人体产生伤害。螨虫类的微尘在几个世纪以来始终成为生物学领域的研究对象，目前为止，已确认有30000种以上。
空气中的污染物质大多通过呼吸来被人吸入并成为各种疾病的根源，当前所知的在对污染物质进行自然净化的过程中起到最重要的作用的是“羟基自由基”，羟基自由基是消除一氧化碳、二氧化硫、二氧 化氮等各种污染物质的大气中的主要净化剂(cleansing agent)。自然界中的羟基自由基以200～2000万个(每1cc空气、每秒基准)的密度存在于空气中。
通常，当前广泛使用的空气净化器及杀菌装置大体分为以下几种。
第一种方式通过吸入净化对象空间的空气来使其经过过滤器并通过过滤器来吸附或分解空气中的污染物质，这是最普遍使用的方式。在长期使用这种方式的情况下，需定期用新的过滤器进行更换，这种维护管理是必须的，但由于过滤器的特性并不完善，因而采用这种方式的空气净化能力的可靠性并不高。
第二种方式为通过使用离子产生装置来增加空气中的离子浓度的方式，当前采用这种方式的空气净化器仅产生负离子，虽然通过负离子进行净化及杀菌的效果可达到一定水平，但无法准确掌握负离子排放量，不仅如此，与强力去除空气中的浮游细菌相关的效果并不高。
第三种方式为使用等离子体团簇离子(Plasma Cluster Ion，PCI)技术的方式，在这里，将采用通过利用等离子体电荷进行的等离子离子空气净化技术，即，通过向空气中排放负离子和正离子并借助与空气中的有害物质之间的化学反应来分解有害物质或使有害物质灭活，从而净化空气。
但是，到目前为止尚未准确探明通过这种方式进行的空气净化过程中的等离子体团簇离子活动的化学原理，不仅如此，无法准确分析离子产生量，因而杀菌效果的可靠性低，目前为止，尚未在微生物学角度上完整地探明正面效果、负面效果。

外罩100包括：第一流路110，用于引导从送风扇500供给的空气；第二流路120，用于对在纯水滤筒内的纯水中所产生的气泡中的气体进行引导；以及第三流路130，使得在第一流路110中流动的空气和第二流路120中的气体相混合。第一流路110的截面积随着远离送风扇逐渐变小，第二流路120的截面积的一部分恒定，但随着靠近第一流路110逐渐变大。第三流路130的截面积随着原理第一流路110和第二流路120逐渐变大。空气在第一流路110中以乱流(Turbulent Flow)方式流动，在第三流路130中以层流(Laminar Flow)方式流动。
第一流路110中的空气通过文丘里效应来吸入在第二流路120中的气泡中所产生的气体。
光催化物质140(例如，TiO 2)涂覆于第二流路120和第三流路130中的至少一个的内壁。
光源150(例如，紫外线发光二极管(UV(Ultra Violet)LED))配置于第二流路120来向光催化物质照射390nm以下的紫外线，由此与通过第二流路120及第三流路130的气体中所包含的过氧化氢(H 2O 2)产生反应，来生成羟基自由基(2OH-)。
臭氧产生部200与第一流路110相连接，始终向第一流路110供给通过高电压产生的臭氧。
本发明一实施例的空气杀菌装置可包括用于向滤筒300投入在臭氧产生部200所产生的一部分臭氧的泵700。
泵700通过与臭氧产生部200相连接的臭氧吸入管710吸入在臭氧产生部200产生的一部分臭氧来通过与滤筒300相连接的臭氧供给管720向滤筒300进行供给。
泵700在臭氧产生部200的工作时间内仅工作一部分时间，例如，每小时仅工作5分钟至10分钟，以此向滤筒300供给臭氧。由此，可在滤筒300内生成充足的过氧化氢，可防止因向滤筒300过度投入臭氧而使羟基自由基的生成量变少的情况。
参照图4，本发明一实施例的滤筒300包括：罐310，用于收容溶液；扩散管320，与臭氧供给管720相连接来向溶液内供给臭氧；以及蒸发部330，吸收溶液来使溶液汽化并向第二流路120流动。
蒸发部330的一部分通过形成于罐310的第一贯通孔340来向作为罐310的外部的第二流路120内露出，剩余一部分配置于罐310内。
蒸发部330吸收溶液并以气体状态向第二流路120供给一部分溶液。蒸发部330由吸湿性材料形成，例如，由选自包括纤维素、纸及海绵组中的一种来形成。
并且，滤筒300可包括通过形成于罐310来用于收容超声波产生部400的槽350。
滤筒300还可包括膜过滤器360，膜过滤器360对在罐310所形成的第二贯通孔341进行涂覆来使源自溶液的气泡中的气体通过，而溶液则无法通过。滤筒300可包括用于投入溶液并通过盖子被盖上的溶液投入口342。
滤筒300的溶液为纯水(DI：Deionized water)或浓度为1％的过氧化氢水。在滤筒300内的溶液不足的情况下，可打开盖子来通过溶液投入口342重新供给纯水或过氧化氢水。
膜过滤器360可包括具有约14亿个/cm 2的气孔并由聚四氟乙烯(polytetrafluoroethylene，ePTFE)形成的多个薄膜。例如，膜过滤器360可为戈尔特斯。
参照图5，本发明另一实施例的滤筒300包括：第一罐311及第二罐312，用于收容溶液；扩散管320，与臭氧供给管720相连接来向第一罐311的下部供给臭氧；连接管321，与第一罐311的上部和第二罐312的下部相连接来向第二罐312供给第一罐311的溶液中的气体；以及蒸发部330，吸收第二罐312的溶液来使溶液汽化并向第二流路120内供给。
蒸发部330的一部分通过形成于第二罐312的第一贯通孔340来向作为第二罐312的外部的第二流路120内露出，剩余一部分配置于第二罐312内。
蒸发部330通过吸收溶液来以气体状态向第二流路120供给一部分溶液。蒸发部330由吸湿性材料形成，例如，由选自包括纤维素、纸及海绵组中的一种来形成。
并且，滤筒300可包括形成于第一罐311及第二罐312中的至少 一个来收容超声波产生部400的槽350。
滤筒300还可包括膜过滤器360，膜过滤器360对在第二罐312所形成的第二贯通孔341进行涂覆来使源自溶液的气泡中的气体通过，而溶液则无法通过。滤筒300可包括用于向第一罐311及第二罐312中的至少一个投入溶液并由盖子被盖上的溶液投入口342。
超声波产生部400插入于滤筒300的槽350来产生超声波。超声波产生部400通过向罐内的溶液施加超声波来分解作为溶液的水，从而生成OH -/H +等的自由基。超声波产生部400通过产生频率在15Khz～10Mhz之间的超声波来向空气中施加，从而使螨虫、酵素、酶的骨架变脆弱。
以下，参照附图，说明本发明一实施例的空气杀菌装置生成羟基自由基的动作。
表1为与通过本发明的空气杀菌装置产生的羟基自由基的生成原理相关的表。
表1
Figure PCTCN2018112481-appb-000001
参照图1至图4，滤筒300包含通过溶液投入口342供给的溶液，例如纯水。泵700通过臭氧吸入管710吸入在臭氧产生部200产生的一部分臭氧来通过臭氧供给管720向滤筒300供给。
向滤筒300供给的臭氧在20℃的温度下以570mg/L的溶解度溶解于作为溶液的纯水。在泵700以3mg/hr的速度向滤筒300投入臭氧来在作为滤筒300的溶液的纯水对臭氧进行10分钟的泡沫化的情况下，进入到溶液中的臭氧达到0.5mg。在滤筒300中的溶液为50mL的情况下，溶液中的臭氧达到0.5mg，在每1mL的溶液中溶解0.01mg的臭氧，在每1L的水中溶解0.01g的臭氧。
若在20℃的温度下投入20分钟的臭氧，则以0.25mg的量溶解于溶液。在此情况下，在滤筒300中的溶液为50mL的情况下，溶解于溶液的臭氧的浓度将达到0.005mg/mL。在这种状态下，若经过20分钟，则臭氧的浓度将减半，达到0.0025mg/mL，再经过20分钟，则臭氧的浓度将再减半，达到0.00125mg/mL。在经过1个小时之后，所溶解的臭氧的浓度将达到1.25mg/l。这种臭氧浓度是足够与水产生反应来生成过氧化氢的量。
通过如上所述的反应式，臭氧通过与水产生反应来产生羟基自由基。
反应式1：O 3+H 2O→H 2O 2+O 2
反应式2：O 3+H 2O 2→OH -+HO 2 ++O 2
用一个反应式表示两个反应则是，
反应式3：2O 3+H 2O→2O 2+OH -+HO 2 +
并且，HO 2 ++O 2→2O 2+OH-→3O 3+H 2O→4O 2+2OH -
滤筒300通过两个连锁反应来生成羟基自由基。
首先，臭氧和水产生反应来生成过氧化氢并生成氧。接着，所生成的过氧化氢和臭氧产生反应来生成两种自由基OH -和HO 2 +。在作为滤筒300内的溶液的脱盐水包含1％的过氧化氢的情况下，通过与向滤筒300投入的臭氧产生反应来更快地生成上述两种自由基和氧。
另一方面，在臭氧和空气向滤筒流入的情况下，空气将包含氮，将在溶液内与臭氧产生不同反应。首先，在滤筒300的溶液内，氮和杂质被氧化来形成硝酸并被溶解。接着，臭氧和水产生反应来根据反应式生成氧和羟基自由基。
参照图5，本发明另一实施例的滤筒300包括：第一罐311及第二罐312，用于收容溶液；扩散管320，与臭氧供给管720相连接来向第一罐311的下部供给臭氧；连接管321，与第一罐311的上部和第二罐312的下部相连接来向第二罐312供给第一罐311的溶液中的气体；以及蒸发部330，吸收第二罐312的溶液来使溶液汽化并向第二流路120内供给。
首先，泵700通过臭氧吸入管710吸入在臭氧产生部200产生的一部分臭氧来通过臭氧供给管720向滤筒300的第一罐311进行供给，从而产生泡沫。氮和杂质与臭氧产生反应来使得被氧化的物质在作为第一罐311的溶液的纯水内被溶解为硝酸。
接着，从第一罐311排出的干净的臭氧通过连接管321向第二罐312供给。去除杂质的臭氧通过与第二罐312中的水产生反应来生成氧和羟基自由基(2O 2+OH -+HO2 +)。
通过这种过程，如同表1所示，在过滤器300中生成通过臭氧、过氧化氢及水产生的自由基(O 2+OH -+HO2 +)(参照在第三列第一行及第三列第二行中记载的自由基)。
接着，滤筒300的蒸发部330通过吸收水蒸汽(和/或过氧化氢)来向第二流路120供给。
并且，滤筒300的膜过滤器360向第二流路120供给作为从通过第二贯通孔341的溶液的气泡中产生的气体的氧、臭氧及自由基(OH -、H +、O -、HO 2 +)。
向第二流路120供给的水蒸汽(和/或过氧化氢)、氧及臭氧通过光催化物质140(例如，TiO 2)和光源150(例如，紫外线发光二极管)产生反应来生成羟基自由基(2OH -)(参照记载于表1中的第一列及第二列的自由基)。
送风扇500使得向第一流路110内投入的空气和从臭氧产生部200排出的臭氧混合。在通过第一流路110的过程中与臭氧相混合的空气在经过第二流路120的过程中产生文丘里效应，来与第二流路120内的水蒸汽(和/或过氧化氢)、臭氧及羟基自由基相混合并向第三流路供给。
向第三流路130供给的水蒸汽(和/或过氧化氢)及臭氧通过光催化物质140(例如，TiO 2)和光源150(例如，紫外线发光二极管)产生反应来生成羟基自由基(2OH -)(参照记载于表1中的第一列及第二列的自由基)。
另一方面，向滤筒100的槽350插入的超声波产生部400通过产生超声波来分解滤筒300内的水，由此产生OH -/H +等的自由基，并通过在第一流路110、第二流路120及第三流路130内使水蒸汽(和/或过氧化氢)产生振动来生成羟基自由基(参照记载于表1中的第六列的自由基)。
通过如上所述的过程产生的羟基自由基与空气一同向第三流路130的外部排出。
本发明的空气杀菌装置在臭氧产生部200产生臭氧，但向第三流路130外部排出的臭氧浓度将根据UL 867的规定来控制在危险控制范围0.001ppm～0.05ppm。
尤其，在臭氧产生部200产生的臭氧通过物理-化学连锁反应来与滤筒300内的溶液及紫外线产生反应，超声波产生部400分解水分子并产生共鸣，通过从送风扇500供给的空气来稀释臭氧，可借助通过紫外线光源和光催化物质产生的反应来充分减少臭氧浓度。
以使臭氧在从本发明的空气杀菌装置的第三流路130相隔5cm的位置达到0.0001g～0.5g的范围的方式调节送风扇500和臭氧产生部200。通过调节送风扇500的风速来以使过氧化氢数达到0.001g～0.5g范围的方式进行汽化，以每cc排放500000～20000000个羟基自由基的方式进行调节。
根据羟基自由基的标准浓度基准(WEL)，每1.4mg/m 3(1ppm)的过氧化氢生成的羟基自由基的量为(1.4mg/m 3)/(34g/mol)＝0.0000411moles/m 3。
由于0.0000411moles/m 3×6.23×10 23＝2.56×10 19molecules/m 3，因而若一个过氧化氢分子生成两个羟基自由基分子，则羟基自由基的最大排放量为2.56×10 19×2＝5.12×10 19/m 3，即，5.12×10 13/mL。
本发明的空气杀菌装置因过氧化氢而可生成(0.008mols)×(6.023×10 23)×2＝9.63×10 21个羟基自由基。若使装置持续工作60天，则将每日平均得到1.6×10 20个的羟基自由基。
当将配置本发明的空气杀菌装置的空间设为300m 3，因过氧化氢而将产生1.6×10 20个/1天/300m 3＝5.33×10 17个/1m 3/1天，相当于5.33×10 11mL/天，这远不能达到上述的标准排放限度。
因此，本发明的空气杀菌装置将通过由多种路径生成的臭氧来生成大量的羟基自由基。
臭氧产生部200通过由高电压电路和控制器驱动的陶瓷电极来生成臭氧，所生成的臭氧通过泵700来被引向滤筒300内部，将在滤筒300内产生气泡。并且，为了对因臭氧和水之间的反应而造成的基于过氧化氢的羟基自由基生成量进行补充，臭氧产生部200将持续向第一流路110供给臭氧。并且，还在滤筒300内部生成臭氧。
另一方面，若因第二流路120中的空气流而被吸入的O -自由基及氧分子和臭氧在作为光催化物质和LED光源所在的反应空间的第二流路120和第三流路130汇合，则使得在滤筒300产生的臭氧和过氧化氢水在生成羟基自由基方面更有效地起到作用。并且，在作为反应空间的第二流路120和第三流路130中产生的空气的乱流(Turbulent Flow)将有助于臭氧和过氧化氢充分混合。
为了在所有羟基自由基生成过程中起到帮助，超声波产生部400将电能转换为机械能来向滤筒300施加超声波。通过向滤筒300内的溶液施加超声波，来产生使水分解成作为OH -/H +等的自由基的强力氧化剂的物理-化学反应。
由此获得的自由基与通过臭氧的分解过程生成的其他自由基组(水蒸汽、氧化水、臭氧、氧等沿着蒸镀有光催化物质(TiO 2)的第二流路120和第三流路130来与空气流一同流入并通过与390nm以下的紫外线之间的连锁反应而生成的自由基)产生反应，并使由此生成的羟基自由基被喷射到空气中。
本发明的空气杀菌装置为了使所生成的羟基自由基能够和负离子一同尽量向宽广的空间散开，以层流的方式向第三流路130的外部排 放。
并且，本发明的空气杀菌装置在滤筒300内的溶液或水的余量达到规定量以上的情况下工作，若在规定量以下的水平，则不进行工作并显示警告标志。
为此，虽然未图示，但本发明的空气杀菌装置可在滤筒300还包括光源、反射部及设置于反射部的传感部，上述传感部对从光源发出并在反射部反射的光进行检测。
若光在滤筒内的溶液或水中往复则将使光量减少，在滤筒内的溶液减少的情况下，传感部接收的光量将增加，由此将提醒需重新投入溶液或需更换滤筒。
以上，仅为本发明较佳的具体实施方式，但发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书的保护范围为准。
