Description
技术领域
本发明涉及一种可高效除去挥发性有机气体的立式室内空气净化器。
背景技术
人们的一生中至少超过一半的时间是在室内度过的，由于室内空间有效，同室外的空间交换较少，室内环境本身不仅没有自然净化能力，而且由于室内装演、空调器等使用的普及以及人们的日常生活，不断地向室内空间排放着污染物质，其中主要是挥发性有机物、固体悬浮颗粒物和气溶胶等，其中主要的污染物包括甲醛和苯系物，这些污染物质的存在，不仅使人产生不良感觉，而且还影响着人们的身体健康，因此随着人们生活水平的提高和空气污染程度的加剧，室内空气污染问题已经越来越受到人们的广泛关注。目前，室内空气净化的方法目前国内外主要采用单纯机械吸附式、静电式、化学(或物理)吸附式、负离子式及光催化式等，由于单纯的机械吸附和静电除尘对于空气净化的效果有限，主要是用于去除悬浮的颗粒物，对于有机污染的净化程度不高，因此已经逐渐被淘汰。而其他几项技术下的产品也各有优缺点，分别适应于不同的污染物净化和不同的客户要求，例如吸附式净化器根据所选吸附材料的特点，可以吸附特定的甚至大部分有机污染物，但存在吸附材料的饱和问题，需要进行材料的再生和更换，对于颗粒物浓度较高的场合，由于颗粒物的堵塞，将影响吸附材料的吸附能力，而负离子有利于有机物的分解，使之形成基本无害的二氧化碳、水和其他无机物，并且还具有一定的空气清新作用，有助于提高空气的品质和舒适度，但反应过程中的产物也在某种程度上对人体产生不利的影响，其对细菌病毒及化学污染物的控制能力也非常有限；几年来，一种快速发展的技术是建立在纳米光催化剂基础上的光催化净化技术，通过纳米光催化剂的催化作用，在紫外线甚至自然光的照射下，对于有机污染物进行分解，并具有较好的杀菌作用，但由于具体作为一种单元操作过程还是有局限性，例如净化效率比较低，实际应用时去除污染物能力有限。因此，需要根据日益增长的生活水平，不断开发出新的功能更多、效果更好、生产成本更低、使用更方便的产品，以满足人们的需要。
发明内容
为克服现有技术的上述缺陷，本发明提供了一种可高效除去挥发性有机气体的立式室内空气净化器，这种净化器可以消除室内空气中的各种主要污染物，这种净化器结构简单，适应方便，净化效果好。
本发明实现上述目的的技术方案是：一种内可高效除去挥发性有机气体的立式室内空气净化器，包括壳体，其壳体内自下到上依次分为臭氧氧化室、光催化反应室和吸附室，所述臭氧氧化室内设有臭氧紫外灯，所述臭氧紫外灯下方设有过滤层，所述光催化反应室内设有光催化紫外灯，所述光催化紫外灯的上方和下方均设有光催化剂滤网，所述吸附室内设有吸附层，所述壳体上顶部设有出风口，下部侧面设有进风口，所述进风口连接于所述过滤层下方的壳体内空间。
本发明的有益效果是：空气自进风口进入壳体内，经过过滤层后滤除其中颗粒物，然后经过臭氧紫外灯附件，臭氧紫外灯所发的紫外光照射产生臭氧，形成强氧化作用，灭活空气中的微生物，并使挥发性有机气体氧化分解为无机物，空气流继续向上移动，经过光催化滤网时，与滤网上的光催化剂碰撞，其中的残存的挥发性有机气体分子与光催化剂上的.OH反应，继续分解，同时，空气中臭氧也被滤网分解，形成氧分子，然后空气流进入吸附层，其中的挥发性有机气体分子被吸附，经过这些净化处理后，从出风口流出。
由于本发明先设有了过滤层，将空气中的颗粒物滤除，不仅仅起到了对颗粒物的净化作用，而且还避免了颗粒物对后续处理过程的危害；由于经过了臭氧氧化和光催化反应，使得空气中的挥发性有机气体分子被分解，两种反应的作用相互协同和补充，可以更为全面的消除各种挥发性有机气体，避免了因单一处理对某些有机物效果不佳的现象，使净化更为全面和彻底，经过这些净化后，进入吸附室的空气中的挥发性有机气体的污染物浓度将大大降低，需要吸附的污染物质量少，因此大幅度提高了吸附材料的使用寿命，避免了因频繁更好吸附材料所带来的麻烦和费用；经过三重的对挥发性有机气体的去除，可以获得很高的净化效果。
