Abstract
本实用新型涉及一种空气净化装置，具体为车辆防噪空气过滤器，包括过环形风道，环形风道有入风口；所述的环形风道中心有环形圈，所述的环形圈由半环形过滤圈和半环形挡风圈组成；所述的半环形挡风圈位于入风口一侧；所述的环形圈之内安装有环形的光触媒板，光触媒板上有通孔，光触媒板两侧有紫外线灯管，光触媒板中心有出风口，所述的出风口位于半环形挡风圈一侧。本实用新型提供的车辆防噪空气过滤器，空气从入风口进入环形风道，将空气的速度降低，延长空气停留时间，并降低风速，减轻噪声。
Description
技术领域
[0001]本实用新型涉及一种空气净化装置，具体为车辆防噪空气过滤器。
背景技术
[0002]高铁或者动车在运行时车体内需保持良好的通风以保证电器元件的可靠工作。车内通风换气是通过机车车体上若干个风机强制排气，由车体两侧侧墙百叶窗进气来实现的。在侧墙百叶窗上都装有空气过滤器用于滤除空气中的沙尘。但是由于车速较快，在进风时候，风速大，容易产生噪声。
实用新型内容
[0003]针对上述技术问题，本实用新型提供一种降低噪声的空气过滤器，具体的技术方案为:
[0004] 车辆防噪空气过滤器，包括过环形风道，环形风道有入风口 ；所述的环形风道中心有环形圈，所述的环形圈由半环形过滤圈和半环形挡风圈组成;所述的半环形挡风圈位于入风口一侧;所述的环形圈之内安装有环形的光触媒板，光触媒板上有通孔，光触媒板两侧有紫外线灯管，光触媒板中心有出风口，所述的出风口位于半环形挡风圈一侧。
[0005]本实用新型提供的车辆防噪空气过滤器，空气从入风口进入环形风道，将空气的速度降低，延长空气停留时间，并降低风速，减轻噪声。
附图说明
[0006]图1是本实用新型的结构示意图。
具体实施方式
[0007]结合附图说明本实用新型的具体实施方式，如图1所示，车辆防噪空气过滤器，包括过环形风道2，环形风道2有入风口 I;所述的环形风道2中心有环形圈，所述的环形圈由半环形过滤圈3和半环形挡风圈6组成;所述的半环形挡风圈6位于入风口 I一侧;所述的环形圈之内安装有环形的光触媒板5，光触媒板5上有通孔，光触媒板5两侧有紫外线灯管7，光触媒板5中心有出风口 4，所述的出风口 4位于半环形挡风圈6—侧。
[0008]所述的车辆防噪空气过滤器，车厢外的空气从入风口 I进入环形风道2，将空气的速度降低，从入风口 I另外一侧半环形过滤圈3进入环形圈，去除灰尘，然后在环形圈内再经过光触媒板5和紫外线灯管7，通过光分解作用，去除空气中有毒有害物质，净化空气，提高车间内的空气质量。最后从出风口4排出，入风口 1、半环形过滤圈3、出风口4的位置相互错开，可以延长空气停留时间，并降低风速，减轻噪声。
Claims (2)
1.车辆防噪空气过滤器，其特征在于:包括过环形风道(2)，环形风道(2)有入风口( I);所述的环形风道(2)中心有环形圈，所述的环形圈由半环形过滤圈(3)和半环形挡风圈(6)组成;所述的半环形挡风圈(6)位于入风口(I)一侧;所述的环形圈之内安装有环形的光触媒板(5)，光触媒板(5)上有通孔，光触媒板(5)两侧有紫外线灯管(7)，光触媒板(5)中心有出风口(4)。
2.根据权利要求1所述的车辆防噪空气过滤器，其特征在于:所述的出风口(4)位于半环形挡风圈(6)—侧。
