Description

个人座舱通风照明装置
本申请要求于2015年12月18日提交的、申请号为201510960268.4的中国专利申请的优先权，在此以参见的方式引入该申请的全部内容。
技术领域
本发明涉及一种个人座舱通风照明装置，更具体来说，本发明涉及一种将利用光触媒的原理对通风管道中的空气的净化与个人座舱的照明相结合的个人座舱通风照明装置。
背景技术
民用客机座舱的空气品质直接影响到乘客的舒适性，有资料表明空气品质不佳会使得机组人员和乘客普遍存在疲劳、头疼和咽喉疼痛等问题。另一方面，为了节省能源而采用的空气再循环系统将座舱排出的空气重新导入座舱进行通风，使空气品质的问题更加严重。
众所周知，光触媒是一种在光的照射下，自身不发生变化，但却能促进化学反应的物质。光触媒在光的照射下，可使材料表面所吸附的氧和水分活性化，产生具有氧化能力极强的自由氢氧基和活性氧，发生氧化反应，以使有机物、细菌、病毒等彻底分解为二氧化碳和水。
光触媒空气净化技术是当前国际上治理环境污染的理想技术。其中，光触媒净化效果优异与否的关键便在于能否更大程度地提高污染空气与光触媒的接触面积以及能否更大程度地保证光触媒表面得到足够的光照射。另外，上述光触媒不仅可以是通过照射紫外光而发生激发的光触媒，也可以是通过照射其它的光(例如可见光)而发生激发的光触媒。
另外，现有的光触媒净化装置按结构主要可分为单流道式、单流道型拓展表面式、蜂窝流道叠加式以及拓展光源式这几种类型。以下，将分别对每种类 型的装置进行简单说明。
(1)单流道式
单流道式结构是典型的光触媒装置结构。在单流道式的光触媒装置中，仅包含一个流道，流道壁面涂有光触媒涂层，而在流道中心布置紫外线灯，通过激发光触媒来实现光催化氧化反应过程。
上海理工大学的金宁等人将初级过滤、高效过滤、活性炭过滤及光触媒催化过滤集成为一个装置进行了研究。这种集成装置1A的结构如图1所示。空气由圆柱筒10A的侧壁10A1进入，在设于内部的风机20A的作用下，空气会先后经过多层过滤网(初效过滤网30A、HEPA高效过滤网40A、活性炭过滤网50A)，到达内层的附着有TiO2(光触媒)的滤网60A上。由于在集成装置1A的圆柱筒10A的中心布置有紫外线双灯管70A，因此，光触媒处于激发状态，污染气体在经过光触媒时会发生氧化还原反应，由此利用多重过滤整体上实现空气净化的过程。
但是，如图1所示，单流道式的缺点在于污染空气与光触媒(TiO2)接触的面积小，因此，其发生反应的反应面积也较小。
(2)单流道型拓展表面式
如上所述，由于单流道式的光触媒装置的反应面积较小，因此，为了提高污染空气与光触媒的反应面积，提出了单流道型拓展表面式结构其中，上述单流道型拓展表面式结构是在单流道式结构的基础上，采用了其它形式的载体，以取代单纯的流道壁面来作为光触媒的附着表面。这种方式增加了光触媒的表面积，由此能够提高装置的反应效率。
闫其年等人对导流回旋风道形式的光触媒装置进行了研究。这种导流回旋风道形式的光触媒装置1B的结构如图2所示。相对于单流道式的光触媒装置，这种导流回旋风道形式的光触媒装置1B采用隔板(未图示)，形成螺旋流道20B。TiO2涂层(光触媒涂层)除了喷涂在管道壁11B上之外，还喷涂附着在隔板上，由此来提高反应面积。四支(在此仅示出了两支)不同辐射波长的紫 外灯管31A、32A布置于装置中央轴线方向，由此来形成谐振光源，以使光触媒处于高强度激发状态。在图2所示的导流回旋风道形式的光触媒装置1B中，由于流道长度与涂层面积均有较大程度地拓展，因此，这两个因素也成为反应效率提高的关键。
此外，赵刚为铁路客车设计了丝网式的光触媒装置，其结构如图3所示。这种丝网式的光触媒装置1C安装于回风管路(未图示)上，呈扁平的抽屉式结构。流道的出口与入口距离较小，且两个端面各布置有一层金属丝网结构。TiO2涂层(光触媒涂层)附着于丝网上，受到流道中间布置的两支紫外灯管10C照射后达到激发状态。由于此装置特殊的外形要求，使得其涂层布置于垂直流道方向，又考虑到不可阻塞流道，因此采用了丝网结构。但是丝网结构对面积拓展有限，并非理想载体形式，导致装置的单次通过反应效率较低。因此，图3所示的这种丝网式的光触媒装置1C的结构仅适用于可重复回风且污染气体浓度较低的情况。
另外，单兴刚等人进行了光催化的实验研究。该研究采用的实验装置为玻璃管套筒的结构形式，在内层的石英管中安装紫外灯管，在外层的玻璃管套筒中填充小玻璃珠颗粒。将TiO2(光触媒)以涂层形式喷涂附着在小玻璃珠上，而形成为填充床的形式，由此能大幅拓展反应面积。
但是，上述三种情形的单流道型拓展表面式的光触媒装置均存在如下缺点：在流道中流动的空气会受到较大的流阻，在对流阻较为敏感的通风系统领域，如交通工具的通风系统中，很可能不满足流阻要求。
(3)蜂窝流道叠加式
蜂窝流道结构与拓展表面式结构同样，都是为了增大反应表面而提出的。但是，由于蜂窝流道较为密集，无法在每个流道内部布置紫外光源，因此，只能在通道的入口与出口位置放置紫外灯管。另外，考虑到光线的照射范围的局限性，流道又不可设置得过长，由此，也就出现了较短的蜂窝流道结构与紫外灯叠加的所谓蜂窝流道叠加式的结构。
北航王浚课题组为旅客机座舱设计的光触媒装置1D就属于这种蜂窝流道 叠加式的结构，其结构如图4所示。采用蜂窝流道的目的，是考虑到与填充床以及图3所示的金属网等形式的结构相比，蜂窝流道式结构的流阻要低得多。另外，将TiO2涂层(光触媒涂层)30D喷涂附着在每个蜂窝流道10D的壁面位置，利用多组紫外灯20D与多个蜂窝流道10D的叠加结构，能使大部分蜂窝通道10D中的紫外线光照条件良好，由此能实现较大的反应效率。
另外，鹿院卫等人同样研究了这种蜂窝流道叠加式结构。所采用的蜂窝流道层板尺寸为300mm×300mm，厚度为6mm，蜂窝孔密度为250×250单元/m2。经过计算验证，研究提出蜂窝通道最佳纵横比为1.5，这个结构比例下，可保证光强得到充分利用。此外，谷昌军等人也对这种结构进行了研究。与鹿院卫等人不同的是，谷昌军等人采用了陶瓷网取代了金属网，同样也取得了较好的实验效果。
但是，上述三种情形的蜂窝流道叠加式的光触媒装置也同样存在如下缺点：在流道中流动的空气会受到较大的流阻，在对流阻较为敏感的通风系统领域，如交通工具的通风系统中，很可能不满足流阻要求。
(4)拓展光源式
除了上述较为常规的光触媒装置类型，还有些研究者另辟蹊径，通过对光路拓展的方式使得光强分布更加均匀，以此提高反应效率。
冯巧莲等人提出了采用光纤作为拓展光源的想法，其构想的光触媒装置1E如图5所示。光纤LF替代了风机BL的叶片，插在风机BL的轮毂H上。而在光纤LF的表面，则覆盖有TiO2的涂层。轮毂中央布置有紫外灯管20E，分布于径向的光纤束可将紫外光源延展至涂层部位，激发光触媒发生光催化反应。但是，此想法并未通过实物实现，其实际效果如何有待验证。
叶剑人则提出了以SiO2为光触媒的载体,其制成的光触媒装置1F如图6所示。实验时，需先制备SiO2的三维骨架，其后将TiO2涂层附着于骨架上，并将骨架以填充床形式安置于装置内部。载体附近布置有紫外灯管。由于光源可通过SiO2扩展光路，因此这种形式的光触媒也属于光源拓展型，对反应效率的提高有很大帮助。
另外，目前光触媒的应用主要集中在民用领域，用于净化房间内空气，提高空气质量。在航天领域中，污染气体的控制目前仍主要采用的是热催化氧化反应器。具体来说，是通过将气体加热至300℃～500℃的高温，并通过催化剂的作用促使VOC等污染气体被氧化为CO2和H2O。而在航空领域中，污染气体的控制目前则仍主要采用臭氧转换器对O3与VOC进行处理，其原理与航天领域中采用的传统的高温催化氧化反应器类似，只是反应条件上会存在一些差异。
同时，光催化氧化反应器相较于传统的高温催化氧化反应器，具有能耗低、结构简单的优点，因而具有良好的应用前景。
通过上述介绍可知，在以往仍然无法存在一种光触媒装置，既能最大程度地提高污染空气与光触媒的接触面积，又能最大程度地保证光触媒表面得到足够的光照射。
因此，如何能够设计一种能够利用满足上述条件的光触媒净化技术，实现提升民用客机座舱的空气品质的结构便成为亟待解决的技术问题。
同时，还希望设计出的上述结构同时能够使在供通风空气流动的通风流道中流动的气流所受到的流阻满足对流阻要求较高的通风系统领域，例如飞机通风系统设计领域。
发明内容
本发明为解决上述技术问题而作，其目的在于提供一种个人座舱通风照明装置，其不仅能最大程度地提高污染空气与光触媒的接触面积，而且能最大程度地保证光触媒表面得到足够的光照射，同时，通过与个人座舱的照明相结合，来实现机舱内部空间的合理利用。
为了实现上述技术问题，本发明提供一种个人座舱通风照明装置，包括装置主体外壳和个人照明组件，所述个人照明组件用于提供个人座舱的照明，其特征是，由所述装置主体外壳的内周面与所述个人照明组件的外周面围起的空间构成通风流道，所述通风流道具有供气入口和供气出口，来 自上游进风部件的空气从所述供气入口流入所述通风流道，并从所述供气出口排出至所述个人座舱所在的空气环境中，在所述装置主体外壳的内周面涂敷有光触媒涂层，在所述个人照明组件的外周面布置有光触媒激发光源，通过所述光触媒激发光源激发所述光触媒涂层，利用光催化氧化反应，对在所述通风流道中流动的所述空气进行净化。
通过如上所述构成，由于将利用光催化氧化反应进行的空气净化与个人座舱的照明相结合，因此，一方面能够实现光触媒的空气在航空、航天领域的应用，另一方面，无需像现有技术这样，另外设置热催化氧化反应器，通过将空气净化与个人座舱的照明结合，实现机舱内部空间的合理利用。
本发明的第二方面的个人座舱通风照明装置是在本发明的第一方面的个人座舱通风照明装置的基础上，其特征是，所述通风流道的靠所述供气入口及所述供气出口一侧的流道的截面积均小于所述通风流道的用于进行所述光催化氧化反应的部分处的流道的截面积。
通过如上所述构成，由于所述通风流道的靠所述供气入口及所述供气出口一侧的流道的截面积均小于所述通风流道的用于进行所述光催化氧化反应的部分处的流道的截面积，因此，能使通风流道呈现出窄-宽-窄的形式，相应地，通风流道中流动的空气流速也会产生快-慢-快的变化。
另外，由于在通风流道的宽幅位置对应地设置有光触媒激发光源和光触媒涂层，由此，能够在保证从供气出口流出的经净化后的空气的流速能够达到所要求的水平的同时，使得进入通风流道中的空气在通风流道(个人座舱通风照明装置)内停留的时间得以增长，因而也使得发生光触媒反应的空气的比例提高。

通过如上所述构成，由于通过旋转上述手动旋钮，能够按压或是释放上述调节弹簧，以使调节弹簧所在的上述个人照明组件(的上述灯罩壳)上下移动，来减小或是增大供气入口141的截面积(开度)，并调节风量(进风量和出风量)，因此，坐在个人座舱上的乘客能够根据自身的需求调节风量，从而能够提高乘坐者的舒适度。
本发明的第五方面的个人座舱通风照明装置是在本发明的第四方面的个人座舱通风照明装置的基础上，其特征是，所述个人照明组件还具有照明光源，所述灯罩壳还具有聚光部分，该聚光部分用于使所述照明光源发出的光会聚。

通过如上所述构成，由于净化后的空气经过所述引导件与所述个人照明组件间的引导流路，流至所述手动旋钮的个人通风喷嘴处，随后流出至所述个人座舱通风照明装置的外部，因此，能使净化后的空气通过个人通风喷嘴排放到更大的范围。

另外，由于将装置主体外壳设计成球状，因此，个人座舱通风照明装置能够在通过连接机构对该个人座舱通风照明装置进行收纳的空间内以一定的角度转动，由此，能够实现从个人通风喷嘴处排放的净化后的空气的方向调节。

具体实施方式
以下，参照图7至图9，对本发明的个人座舱通风照明装置100进行 说明。其中，图7是示意表示本发明实施方式的个人座舱通风照明装置100的结构的示意图，图8是对图7所示的个人座舱通风照明装置100的结构原理进行说明的图，其中示出了装置主体外壳110、个人照明组件120、流量调节机构130、供通风空气流动的通风流道140、光触媒激发光源150、光触媒涂层160等构件，图9是示意表示设置在图8所示的个人座舱通风照明装置100中的激发光源安装面上的光触媒激发光源150布置的展开示意图。
如图7所示，本发明一实施方式的个人座舱通风照明装置100包括装置主体外壳110、个人照明组件120、流量调节机构130。上述个人座舱通风照明装置100是将通风功能和照明功能结合的装置。由装置主体外壳110的内周面和个人照明组件120的外周面(下面有时也称为“激发光源安装面”)围起的空间构成供通风空气流动的通风流道140。
如图7和图8所示，上述个人照明组件120具有照明光源121和灯罩壳122。上述照明光源121例如是LED灯，但不局限于此，也可以是其它任意合适的光源。如图7所示，上述灯罩壳122作为一例，例如具有呈柱状的灯罩壳主体122a、聚光部分122b以及呈柱状的激发光源安装部分122c，其中，上述聚光部分122b用于使照明光源121发出的光会聚，以提供更明亮的光照。另外，上述光触媒激发光源150布置在上述激发光源安装部分122c的外表面、即激发光源安装面上。
上述流量调节机构130具有手动旋钮131、调节弹簧132以及调节基座133。上述手动旋钮131设置在装置主体外壳110的出口端，并形成为能相对于装置的轴线旋转。在上述手动旋钮131的内部形成有靠装置外部一侧的开口比靠装置内部一侧的开口大的个人通风喷嘴131a。上述调节弹簧132形成在上述灯罩壳122的灯罩壳主体122a与激发光源安装部分122c之间，调节弹簧132的一端与上述手动旋钮131连接，另一端连接在上述灯罩壳122a的顶端。上述调节基座133设置在装置主体外壳110的入口端。
上述调节基座133与上述装置主体外壳110的入口端间形成有用于使空气从上游通风管路等部件流入至个人座舱通风照明装置100的通风流道 140的供气入口141，上述个人照明组件120(在本实施方式中，更具体来说是个人照明组件120的灯罩壳122b的聚光部分122b)与上述装置主体外壳110的出口端间形成有供空气流出通风流道140的供气出口142。在供气入口141与供气出口142间的流道中，对流过其中的空气进行净化。另外，在上述装置主体外壳110的出口端还设置有引导件111，从供气出口142流出的净化后的空气经过引导件111与个人照明组件120间的引导流路，流至手动旋钮131的个人通风喷嘴131a处，随后流出至个人座舱通风照明装置100的外部。
通过旋转上述手动旋钮131，能够按压或是释放上述调节弹簧132，以使调节弹簧132所在的上述个人照明组件120(的上述灯罩壳122)上下移动，来减小或是增大供气入口141的截面积(开度)，并调节风量(进风量和出风量)。
在装置主体外壳110的内表面，形成有光触媒涂层160。上述光触媒涂层160例如可以涂在装置主体外壳110的整个内表面，也可以根据光触媒激发光源150的设置位置进行调整。
如图9所示，在本实施方式中，多个光触媒激发光源150在整个圆周上彼此间隔开一定间隔地布置在呈柱状的激发光源安装部分122c的外周面(激发光源安装面)上。
在本实施方式中，较为理想的是，如图7所示，使装置主体外壳110呈球状，并且使个人照明组件120呈柱状。通过这样，能使通风流道140呈现出窄-宽-窄的形式。相应地，通风流道140中流动的空气流速也会产生快-慢-快的变化。
另外，装置主体外壳110也可以如图8所示形成为使靠通风流道140的供气入口141一侧的径向宽度小于位于通风流道140的用于进行光触媒净化的部分处的径向宽度。另外，虽未图示，但同样地，装置主体外壳110的靠通风流道140的供气出口142一侧的径向宽度也小于位于通风流道140的用于进行光触媒净化的部分处的径向宽度。由此，根据图8所示的结构，也能够使通风流道140呈现出窄-宽-窄的形式，具有与图7所示的结构相当 的技术效果。
另外，由于在通风流道140的宽幅位置对应地设置有光触媒激发光源150和光触媒涂层160，由此，能够在保证从供气出口142流出的经净化后的空气的流速能够达到所要求的水平的同时，使得进入通风流道140中的空气在通风流道140(个人座舱通风照明装置100)内停留的时间得以增长，因而也使得发生光触媒反应的空气的比例提高。
除此之外，将装置主体外壳110设计成球状，使得个人座舱通风照明装置100能够在通过连接机构对该个人座舱通风照明装置100进行收纳的空间内以一定的角度转动，由此，能够实现从个人通风喷嘴131a处排放的净化后的空气的方向调节。
另外，由于进入到通风流道140(个人座舱通风照明装置100内部)的(污染)空气在经过由光触媒激发光源150进行了照射后的光触媒涂层160时，能够利用光催化氧化反应，实现对(污染)空气中的一部分VOC气体的去除，从而实现空气净化功能。
接着，参照图10和图11，对本发明的个人座舱通风照明装置100的变形例进行说明。
在本变形例中，对于与上述实施方式相同或相当的构件标注相同的标号，并省略其详细说明。另外，仅对与上述实施方式不同的构造、形状等进行展开说明。
在上述实施方式中，对装置主体外壳110整体呈大致球状(图7)、个人照明组件120整体呈柱状的情况进行了说明，其中，个人照明组件120整体既可以呈大致圆柱状，也可以呈大致四棱柱这样的方柱状。
另外，在本发明中，只要形成为使通风流道140中的用于进行光触媒净化的流道的截面积大于通风流道140的供气入口141及供气出口142处的流道的截面积，则装置主体外壳110和个人照明组件120的整体形状可以适当地选择。
例如，在图8中，示出了装置主体外壳110的靠通风流道140的供气 入口141及供气出口142一侧的径向宽度均小于位于通风流道140的用于进行光触媒净化的部分处的径向宽度，而个人照明组件120整体呈柱状的结构，但本实用新型不局限于此，例如也可以如图10所示，使个人照明组件120整体呈锥台形状。只要能够在保证从供气出口142流出的经净化后的空气的流速能够达到所要求的水平的同时，使得进入通风流道140中的空气在通风流道140(个人座舱通风照明装置100)内停留的时间得以增长即可。
在如图10所示这样的结构中，灯罩壳122整体(特别是激发光源安装部分122c)呈锥台状，当如图11这样俯视观察时，多个光触媒激发光源150在整个灯罩壳122的外周上彼此间隔开一定间隔地布置在激发光源安装部分122c的外周面(激发光源安装面)上。
当然，光触媒激发光源150也可以形成在激发光源安装部分122c的整个外周面上，这点是自不待言的。
熟悉本领域的技术人员易于想到其它的优点和修改。因此，在其更宽泛的上来说，本发明并不局限于这里所示和所描述的具体细节和代表性实施例。因此，可以在不脱离如所附权利要求书及其等价物所限定的总体发明概念的精神或范围的前提下做出修改。
例如，在本发明的实施方式中，示出了上述调节弹簧132的另一端连接在上述灯罩壳122a的顶端的情况，但本发明不局限于此，也可以连接在灯罩壳122a的其它部分，除此之外，只要通过调节弹簧132的按压、释放，能使个人照明组件120相对于装置主体外壳110(个人座舱通风照明装置100)上下移动，则调节弹簧132与个人照明组件120连接的连接位置不局限于灯罩壳122a的顶端，也不局限于灯罩壳122a。
