Description

一种空气过滤装置 技术领域
本发明属于空气治理设备技术领域，具体涉及一种空气过滤装置。
 背景技术
 室内空气中除了灰尘还有一定的污染物，例如SO 2、NO 2、HCL、HF、NH₃等，这些污染物用普通的过滤方法无法去除。
传统的空气过滤设备主要通过滤芯等结构实现过滤，滤芯为耗材，更换成本较高，而且滤芯的阻力大，影响空气过滤的速度，不适合大面积场所使用。另外采用净化液作为空气过滤方法的设备一般直接把空气通入到净化液中进行反应过滤，此方法中空气和净化液的接触面积较小，过滤效果有很大的提升空间。
现有的空气净化设备功能一般单一，具备加湿功能的也是直接叠加一个加湿器模块，没有在过滤同时加湿的处理。
 技术问题
本发明目的之一是在污染较轻的室内实现过滤的同时加入加湿功能；本发明目的之二是在污染较重的室内实现二级过滤。
 技术解决方案
针对背景技术提出的问题，本发明提出一种空气过滤装置，技术方案如下：
 一种空气过滤装置，包括车体，其中，车体上固定有若干净化装置，净化箱，所述净化装置内部两侧设置有静电板，净化装置顶部设置进风口，进风口底部设置进气扇；净化装置底部内侧设置排气扇，排气扇出口连通出气管，出气管伸入到净化箱中，净化箱中装有净化液，净化液为水或者氢氧化钠溶液，净化箱顶部设置防溅网，所述出气管在净化箱中分为若干连通的喷雾管，每个喷雾管和一个吸管连通，所述吸管底端插入净化液底部，吸管顶端嵌入到喷雾管中，吸管顶端成斜面且迎气流方向高，背气流方向低，所述净化液为水，过滤同时实现自然加湿；所述净化液为氢氧化钠溶液，实现物理化学两级过滤。。
进一步的，净化装置底部外侧设置排污口。
进一步的，防溅网为双层结构，靠近液面的底层孔隙大于顶层孔隙，底层和顶层之间设有间隙。
进一步的，间隙中加有过滤包。
进一步的，净化箱内，防溅网底部设置有斜面。
进一步的，净化箱内部通路中设置除雾器。
进一步的，净化箱底部外侧设置排液口。
 有益效果
本装置结构简单，二级过滤结构使本装置的过滤效果更好，净化箱中加入水可以满足常规使用，在过滤过程中实现加湿功能。净化箱中加入NaOH溶液可清除多种污染物，适用于室内污染严重的情况，同时喷雾设计加大了空气和液体的接触面积，提高了过滤效果，独特的防溅设计有效的防治气雾溢出。
 附图说明

 图2是本发明实施例1净化箱内部结构示意图；
 图3是本发明防溅网结构示意图；
 图4是本发明实施例2净化箱内部结构示意图；

 本发明的实施方式
实施例1，使用条件，当室内空气质量较好且需要加湿的时候，过滤的同时进行加湿操作，一种空气过滤装置，车体上对称固定有两个净化装置2，车体中间设置净化箱6，净化装置内部两侧设置有静电板9，净化装置顶部设置进风口3，进风口底部设置进气扇4；净化装置底部内侧设置排气扇8，排气扇出口连通出气管5，出气管伸入到净化箱中，净化箱中装有水，净化箱顶部设置防溅网12，防溅网为双层结构，靠近液面的底层孔隙大于顶层孔隙，底层和顶层之间设有间隙。出气管在净化箱中分为若干连通的喷雾管10，每个喷雾管和一个吸管11连通，所述吸管底端插入净化液底部，吸管顶端嵌入到喷雾管10中，吸管顶端成斜面，迎气流方向高，背气流方向低，。
接通电源，打开装置，静电过滤为成熟的现有技术，空气由进风口吸入，经过净化装置内部，灰尘等颗粒被吸附到静电板上，过滤后的气体由出气管排出，通入到净化箱中。由于吸管顶端嵌入到喷雾管中，迎气流方向高，背气流方向低形成负压，依据伯努利原理，水被吸上来和空气夹杂在一起形成气雾，一方面增加了水和空气的接触面积，进一步提升了灰尘的吸附，使过滤效果更好，另一方面，给空气加湿，使排出的空气含水量增加，过滤同时起到自然加湿的效果。
净化装置底部外侧设置排污口，当需要对静电板清理的时候，打开进气口用工具刮掉静电板上灰尘，从排污口排出。
净化箱内，防溅网底部设置有斜面，有助于凝聚的水滴流回净化箱。
净化箱底部外侧设置排液口，换水时可以打开排液口进行排水，打开防溅网进行加水。
实施例2，使用条件，当室内空气污染较严重，净化箱中加入氢氧化钠溶液，净化箱内部通路中设置除雾器，除雾器为常用器件，属于现有技术通过多个紧密排列的波形板实现除雾；同时防溅网为双层结构，靠近液面的底层孔隙大于顶层孔隙，底层和顶层之间设有间隙，间隙中加有过滤包，过滤包中可以是和氢氧化钠溶液反应的固体粉末，例如碳酸氢钠粉末，碳酸氢钠和氢氧化钠反应生成碳酸钠和水，用于吸附极少量的氢氧化钠水雾，防止溢出污染。其他描述同实施例1。
使用时，接通电源，打开装置，空气由进风口吸入，经过净化装置内部，灰尘等颗粒被吸附到静电板上，过滤后的气体由出气管排出，通入到净化箱中。由于吸管顶端嵌入到喷雾管中，吸管迎气流方向高，背气流方向低形成负压，依据伯努利原理NaOH溶液被吸上来和空气夹杂在一起形成气雾，增加了NaOH和空气的接触面积，进一步提升了过滤效果，可以消除空气中的SO 2、NO 2、HCL、HF、NH₃等有害气体，还可以消除CO 2，使过滤效果更好。过滤后的气体从防溅网排出，防溅网中设置碳酸氢钠过滤包，吸附溢出的少量氢氧化钠水雾。净化箱内，防溅网底部设置有斜面，有助于凝聚的NaOH液滴流回净化箱。净化箱的整体结构，气路路径以及雾化器保证了大部分NaOH液雾凝聚回流，极少溢出部分由过滤包吸附，避免溢出污染。
此外，应当理解，虽然本说明书按照实施方式加以描述，但并非每个实施方式仅包含一个独立的技术方案，本领域技术人员应当将说明书作为一个整体，各实施例中的技术方案也可以经适当组合，形成本领域技术人员可以理解的其他实施方式。
 工业实用性
通过选用不同净化液适用于污染较轻的室内和污染较重的室内，实用性强。
