Description

一种多通道去除气载微生物粒子净化器 技术领域
本发明涉及室内空气净化领域，可用于对室内空气中微生物粒子进行收集净化，并灭活收集后的微生物粒子。
 背景技术
目前空气净化器内主要使用HEPA滤网对气载颗粒进行收集净化。这种方法可以高效过滤粒子，但HEPA滤网为多孔介质，在吸附水蒸气或颗粒的水分之后，极易成为微生物繁殖的场所，一旦这些微生物气溶胶化而进入室内空气中，将造成空气的二次污染。UVC紫外灯对微生物有高效的灭活杀菌效果，然而HEPA滤网的多孔结构将阻碍紫外光射入，难以保证杀灭微生物所需的紫外光剂量。采用惯性撞击原理设计的颗粒收集或净化装置可将气载微生物收集到固体表面，有利于UVC紫外灯的照射。为实现较理想的粒子收集效果，惯性撞击的气流速度很大，噪音也较大。但是用于室内气载微生物净化的洁净空气量却是动态变化的，如何保证不同空气流量下良好的粒子收集效果，是困扰行业由来已久的一个难题。本发明提出一种多通道粒子惯性撞击净化器，通过串级净化单元通道开启数目的联动，来满足当需求的净化器运行风量改变时，净化器对微生物粒子的撞击收集仍然有良好的效果，并辅以UVC灯的照射，实现不同运行风量下良好的空气微生物净化效果。
 技术问题
针对以上现有技术存在的问题，本发明公开了一种多通道去除气载微生物粒子净化器。
 技术解决方案
具体技术方案为：
一种多通道去除气载微生物粒子净化器，包括过滤模块，离心风机和壳体；所述过滤模块至少包括两个净化单元，每个净化单元结构相同，所述净化单元包括风阀、气流射流器、颗粒收集板；空气通过风阀沿气流通道进入气流射流器；所述气流射流器上有多个射流喷嘴，空气流经喷嘴形成高速气流并撞击到颗粒收集板上；所述颗粒收集板上有多个凹槽，每个凹槽位置与射流喷嘴位置一一对应。
进一步地，所述过滤模块的不同净化单元之间通过风阀独立控制是否开启该净化单元的气流通道。当净化器风量发生变化时，通过控制净化单元的开启个数，从而控制气流流过喷嘴后的射流速度稳定不变。
进一步地，所述净化器至少包括两个串联在一起的过滤模块，不同过滤模块之间前后设置，大压头风机，如离心风机，设在过滤模块之间，用于降低风机运行的噪音对室内的影响。
进一步地，所述过滤模块还包括紫外杀菌灯，至少一个紫外杀菌灯设置于净化单元的气流射流器和颗粒收集板的空隙间，紫外杀菌灯直接照射颗粒收集板上的凹槽，对收集板的微生物粒子灭活。
进一步地，所述净化器在装置不同运行风量下，通过联动控制装置，控制不同层级过滤模块的净化单元风阀开启的个数，使气流射流速基本不变，且不同层级过滤模块的净化单元风阀开启的个数相同。
进一步地，所述风阀设置在每个净化单元气流通道的进风端或出风端，射流喷嘴沿空气走向可为渐缩通道，以对空气进行加速。
 有益效果
本发明的创新点和有益效果为：每层过滤模块内设置了多个净化单元，每个净化单元设有调节风阀，控制该净化单元通道的开度及开闭。净化单元内设置射流器和颗粒收集板。射流器上有多个喷嘴，每个喷嘴流量可达到十几立方米每小时，气流流通过后，微生物粒子将被颗粒收集板收集。颗粒收集板上的收集槽可为凹形结构，可以适当减少微生物粒子的反弹。通过风阀对净化单元通道的控制以保证净化器风量改变时，流过每个加速喷嘴的气流射流速度基本不变，净化单元的过滤效率也就基本不变。从而使本净化器成为一种可分档调节风量、且保持气载微生物粒子良好净化效果、并具有较低噪音水平的净化装置。
每个净化单元内置有紫外杀菌灯，可照射收集槽表面，对收集板内微生物粒子进行长时间、大剂量照射灭活，获得良好的杀菌消毒效果。每个净化单元的收集板和射流器可进行拆卸清洗，以保持长时间运行后净化效果不下降，具有维护方便、运行费用低的优势。
 附图说明
图1为本发明的主结构图；
图2为本发明的一个过滤模块剖面图；
1第一层过滤模块；2第一层过滤模块某一净化单元；3风阀；4气流射流器；5紫外杀菌灯；6颗粒收集板；7大压头风机；8第二层过滤模块；9第二层过滤模块某一净化单元。
 本发明的实施方式
本发明将通过调节每层过滤模块上净化单元通道开启的个数，保证净化器各档风量下净化单元内气流的射流速度基本不变，下面结合附图阐述本发明的具体结构和实施方法。
一种多通道去除气载微生物粒子净化器，如图1所示。包括过滤模块1，离心风机6和壳体。所述过滤模块1至少包括两个净化单元2，所述净化单元由风阀3、气流射流器4、颗粒收集板5组成。射流器内有喷嘴，收集板内有收集槽，所述风阀设1置在各个通风通道中，可旋转启闭和调节开度。
一、气流流向：当净化器风机启动时自上而下吸入气流，气流进入每层风阀开启的净化单元通道，经射流器的喷嘴形成高速射流，使气流中的粒子因惯性被收集到圆弧凹槽的收集板中。紫外灯照射收集槽，对被收集的微生物颗粒进行灭活。
二、风阀的调节：当风机转速最大时，每层过滤模块净化单元的风阀全部都打开，风量最大，上述气流通过所有净化单元的射流喷嘴。当净化器风量减少时，每层过滤模块上只有部分净化单元开启，通过联动控制，使不同层过滤模块上开启的净化单元数目相同，上述气流通过开启的净化单元的射流喷嘴，即使总风量改变仍保持喷嘴通道内气流射流速度基本不变。当风机转速最小时，每层过滤模块上只有一个净化单元开启，使喷嘴通道内气流射流速度仍基本不变，维持良好的颗粒撞击收集效果。
