Description

车载净化新风装置
技术领域
车载净化新风装置，特别一种安装在车辆发动机舱内货舱外，向乘员舱供应净化新风的集成化总成。
背景技术
现有的绝大多数车载新风装置，只有一个滤网，或极少量的活性炭。这种滤网的容尘量很低，很快就会堵塞，需要经常更换。只能实现对于颗粒物的过滤，不能长期有效过滤空气中的气相污染物，特别是在低速行驶中，公路上车辆排出的废气就会进入乘员舱，对成员产生伤害。这种障碍使得大多数情况下司乘人员选择使用内循环，而由于乘员舱空间狭小，人员密集，很容易引起舱内二氧化碳迅速富集，往往只要30分钟，就能达到3000---4000ppm，造成司乘人员缺氧、注意力下降、嗜睡，进而影响驾驶安全和舒适度，甚至影响健康。
从技术层面上分析，造成这些问题的核心是：1、滤网的容尘量不足，2、缺乏对气相污染物有效的过滤措施。
发明内容
上述问题的出路在于选择一种容尘量巨大，可恢复、可免维护的滤材；增加气相污染物处理净化环节。根据这个原理，本发明就是根据这个原理提出的一种解决方案。
车载净化新风装置，由中空纤维膜滤芯、滤芯壳体、风机马达、气罩、反吹阀、通气阀、消杀器、高压气囊、反吹高压气源、气体处理盒、出气口组成；本装置总成安装在车的发动机舱内或舱外，所述出气口与乘员舱相通；
所述中空纤维膜滤芯安装在所述滤芯壳体中，所述滤芯壳体是一个周围布满2---10mm通孔的薄壳体；
所述滤芯壳体内装有消杀器，所述消杀器是臭氧发生器和紫外线发生器，所述消杀器只在发动机关闭时才运行；
所述中空纤维膜滤芯的上端部与气罩相连接，所述气罩上接有反吹阀和通气阀或反吹与通气结合的三通阀；
所述通气阀的另一端通过管路连接到风机马达的进风端，所述风机马达的出风端通过管路连接气体处理盒的进风端，所述气体处理盒是一个填充了活性炭或分子筛气体处理填料的盒体，这些气体处理填料的总量为50克---100000克，所述气体处理盒采用可拆卸安装结构，所述气体处理盒的另一端有有出气口，所述出气口与乘员舱的空气循环系统连接，将新风送入乘员舱；
所述反吹阀的进气端通过管路与高压气囊连接，高压气囊通过管道与高压气源连接，所述高压气源是一个压力为0.3---0.8mpa的高压气泵或车载的压缩空气接头；
所述气罩上连接的反吹阀和通气阀或反吹与通气结合的三通阀，被程序控制，在过滤工况和反吹工况两种状态之间交替工作。
所述中空纤维膜滤芯，是聚四氟乙烯中空纤维膜组成的集束，其膜丝直径2---10mm。
本发明车载净化新风装置采用的中空纤维膜滤芯，是聚四氟乙烯中空纤维膜，其膜丝直径2---10mm。
附图说明
图1是一个车载净化新风装置的原理结构示意图。图中(1) 中空纤维膜滤芯；(2)滤芯壳体；(3) 消杀器；（4）气罩；(5) 反吹高压气源；（6）高压气囊；（7）反吹阀；(8) 通气阀； (10)风机马达；(11) 气体处理盒；(12) 出气口。
具体实施
由于采用了中空纤维膜滤芯，特别是聚四氟乙烯中空纤维膜，具备了对于粉尘的微克级过滤精度和极大的容尘量，同时采用了反吹结构，滤芯可以实现免维护、免更换长期运行，直至伴随车辆寿命终生。采用了消杀器，可以有效杀灭滤芯上的病原体，保障了新风的安全性。采用了大容量的活性炭、分子筛等气体处理填料，可以彻底吸收二氧化硫、一氧化碳、氮化物、VOC等有害物质，保障了新风的气体成分洁净度。由于粉尘被彻底过滤，使得活性炭等微孔吸附材料的寿命大幅度延长。实验室试验和车辆现场试验表明，在低速、长时间行驶时，乘员舱的空气质量有了根本性的改善。
