具体实施方式
路灯是公路和城市大街小巷道路两旁必不可少的照明设施，特别是马路两旁的路灯能够最先和机动车尾气接触的设施，每天被数以万计的汽车的排放的尾气弥漫在路灯周围。相关技术中的路灯仅具有照明功能，却不具有消除霾的作用，如果路灯能够具有消除霾的作用，将对于保护环境将起到巨大作用，同时，也有望无需限号，保证人们正常出行。
如图1-图7所示，本实施例提供一种路灯，该路灯为除霾式，所述除霾式路灯不仅具有提供照明的功能，而且还具有除霾功能，能够有效清除马路上机动车辆排放的尾气，防止雾霾产生，起到保护环境的作用。
在一实施例中，请参见图1，图1是路灯的结构示意图。除霾式路灯包括灯杆1、灯罩2、灯罩电线支架管3、照明灯4以及空气净化装置，灯罩2通过灯罩电线支架管3安装于灯杆1，照明灯4安装于灯罩2，照明灯4设置为提供照明，风机14设置于灯杆1，通过风机14对待净化空气进行净化。待净化空气为汽车尾气和 大气雾霾等。本实施例中的除霾式路灯的灯杆1，也可以替换为电力电杆、移动通信天线钢杆、户外广告牌钢杆、道路两旁设置为提示驾驶员行车注意信息的警示牌支撑杆、红绿灯支撑杆和摄像头支撑杆等。
在一实施例中，该除霾式路灯还设有风机14，空气净化装置设置于灯杆1内部，在其他实施例中空气净化装置也可以设置在灯杆1外部，但是空气净化装置设置在灯杆1外部时，会影响除霾式路灯的美观。灯杆1上设有出风口15和进风口18，并且出风口15和进风口18通过风机14与外界大气连通，风机14位于进风口18和出风口15之间，空气净化装置位于进风口18和风机14之间。本实施例中，出风口15、风机14、空气净化装置和进风口18由上至下依次设置在灯杆1上，在其他实施例中，出风口15、风机14、空气净化装置和进风口18也可以沿水平方向依次设置，或者沿L型方向依次设置。
灯杆1可以通过地脚螺栓38安装在马路两旁的地面上，也可以在马路两旁的地面下预先埋设基础底座，将灯杆1可以通过地脚螺栓38固定在底座上。运行时，风机14运转，灯杆1内部形成负压，机动车尾气和大气雾霾等待净化空气经进风口18被吸入灯杆1内部，被灯杆1内配置的空气净化装置净化，清除待净化空气中的有害颗粒和有害气体，净化后的空气由出风口15排向大气。
灯杆1上还设有风机段13和进风段17，风机段13和进风段17均位于灯杆1内部，风机14安装于风机段13，进风口18设置于进风段17。灯杆1还包括配电箱5和电缆6，电缆6设置为与市电连接，配电箱5设置为对风机14以及空气净化装置内部的用电部件供电。该灯杆1顶部还设有风帽16，风帽16设置为将灯杆1内部的空腔顶部的开口遮蔽。由于路灯配置在马路两旁，与机动车近在咫尺，机动车尾气实时被吸入灯杆1内部，并通过空气净化装置消除尾气中的有害颗粒和有害气体。
空气净化装置可以通过水洗、过滤、吸附、静电除尘、负离子、等离子或三元催化、光氢离子、催化燃烧、生物、紫外线、光分解或光融媒等空气净化装置对待净化空气进行净化，设计灯杆1时，不仅要顾及灯杆1的整体美观，也要考虑除霾的效果。考虑到当空气净化装置采用上述不同方式的净化方案，体积的大小也不相同，因而灯杆1的直径大小，应该按照空气净化装置的具体体积进行合理配置。
除霾式路灯还包括PM2.5检测控制装置41，PM2.5检测控制装置41设置为控制风机14和空气净化装置的开启或关闭，从而可以实现自动消除机动车尾气和 大气雾霾。如果是控制一条除霾式路灯线路(包括多个除霾式路灯)，为了节省投资，那么PM2.5检测控制装置41可以集中设置一个或多个，进行多点PM2.5监控后，根据PM2.5值，统一控制该条除霾式路灯线路中多个除霾式路灯的风机14和空气净化装置的开启或关闭，实现智能除霾控制。
请参见图2，图2是喷淋水洗大气净化路灯结构示意图。除霾式路灯的空气净化装置包括至少一个喷嘴7、储液罐9、喷淋泵11和喷淋液管道12，储液罐9内储存有喷淋液10，储液罐9与喷淋泵11连接，喷淋泵11通过喷淋液管道12与至少一个喷嘴7连接，喷嘴7位于风机14和进风口18之间，喷嘴7能够将喷淋液10喷出并形成喷淋水雾8，喷淋水雾8设置为对待净化空气进行水洗净化。储液罐9设置于灯杆1内部的底端，经喷嘴7喷出的喷淋液10落入到储液罐9内。本实施例中，该除霾式路灯设有两个喷嘴7，两个喷嘴7沿高度方向上下设置。本实施例对于喷嘴7的具体个数并不进行限定，对于设置有多个喷嘴7时，多个喷嘴7的位置关系也不限定，例如，还可以将多个喷嘴7沿同一水平面间隔设置，还可以纵向垂直间隔设置。本实施例中，喷淋泵11位于储液罐9的喷淋液10内，该喷淋泵11为潜水泵，在其他的实施例中，该喷淋泵11也可以设置于储液罐9外部，可以为抽水水泵。
喷淋泵11运转，喷淋液10经喷淋液管道12送入每个喷嘴7，多个喷嘴7向下喷淋水雾8，此时风机14同时运行，机动车尾气和大气雾霾等待净化空气从进风口18被吸入灯杆1内，随着待净化空气向上方流动，待净化空气与喷淋水雾8逆向摩擦洗涤，由于汽车尾气中的有害气体易溶于水，所以尾气和PM2.5溶于喷淋液10中而被清除，净化后的清洁空气经出风口15吹向大气。
如图8所示，该除霾式路灯还包括浊度检测控制装置39，储液罐9上设有供液端和排液端，供液端设有供水电磁阀19，排液端设有排水电磁阀20，储液罐9内设有水位控制装置40，浊度检测控制装置39设置为检测喷淋液10的浊度并控制排水电磁阀20的开启或关闭，在一实施例中，当喷淋液10中PM2.5和污染物及污垢系数达到设定值时，由浑浊度检测控制装置39自动控制排水电动阀20打开和关闭，将污水排放至城市下水管道37中统一由污水处理厂处理，水位控制装置40设置为检测喷淋液10的液位高度并控制供水电磁阀19的开启或关闭，供水电磁阀19具体由配电箱5内配置的智能自动控制系统打开并向储液罐9内注入自来水。在一实施例中，当储液罐9内自来水注入到一定容积后由储液罐9内配置的液位控制器自动关闭供水电磁阀19，停止注入自来水。
该除霾式路灯还包括气水分离器21和电缆线护套管22，其中，气水分离器21设置在风机14下方，并位于多个喷嘴7的上方，因为喷嘴7喷淋出的喷淋水雾8容易在风机14的驱动下从出风口15排到外界，造成储液罐9无法回收该部分喷淋液10，而通过设置气水分离器21，能够有效阻止喷淋水雾8的消耗。电缆线护套管22固定在灯杆1侧壁上，并且沿竖直方向延伸，由于灯杆1内部处于水气环境中，为了保证供电安全，供给风机14电力的电缆穿设于电缆线护套管22内。
当环境温度较低时，自来水可以用防冻液替代。在一实施例中，当室外温度大于0℃时，储液罐9内注入的喷淋液10是水，在一实施例中喷淋液10为自来水；当室外温度不大于0℃时，储液罐9内注入的喷淋液10是防冻液。附图2所示的喷淋水洗大气净化除霾式路灯，该路灯的净化效果非常理想，能够有效消除汽车尾气和大气PM2.5，因大气中的臭氧O3、二氧化硫、二氧化氮、甲醛等有害气体易溶于水，所该除霾式路灯还可以消除大气中的臭氧O3、二氧化硫、二氧化氮和甲醛等有害气体。
请参见图3，图3是大气过滤净化路灯结构示意图。该除霾式路灯的空气净化装置包括依次设置的初效过滤段23、中效过滤段25和高效过滤段27，本实施例中，初效过滤段23、中效过滤段25和高效过滤段27沿待净化空气的流动方向依次设置，待净化空气能够依次经过初效过滤段23、中效过滤段25和高效过滤段27，初效过滤段23包括至少一个初效过滤器24，中效过滤段25包括至少一个中效过滤器26，高效过滤段27包括至少一个高效过滤器28，初效过滤器24、中效过滤器26和高效过滤器28均设置为对待净化空气进行净化。空气净化装置运行时，汽车尾气和大气雾霾等待净化空气由风机14驱动，先经初效过滤段23，通过初效过滤器24初步过滤后再经中效过滤段25，通过中效过滤器26过滤最终经高效过滤段27，利用高效过滤器28高效滤除PM2.5。
请参见图4，图4是过滤和活性炭吸附大气净化路灯结构示意图。该净化除霾式路灯和图3所示的净化除霾式路灯的区别在于，该净化除霾式路灯的空气净化装置还包括设置在初效过滤段23和中效过滤段25之间的活性炭颗粒过滤段29，活性炭颗粒过滤段29包括活性炭颗粒吸附装置30，在初效过滤器24和中效过滤器26之间通过活性炭颗粒过滤段29的活性炭颗粒吸附装置30对机动车尾气和大气中的有害气体进一步净化。
请参见图5，图5是静电除尘大气净化路灯结构示意图。该净化除霾式路灯的空气净化装置包括高压放电电极32，灯杆1的内部设有静电除尘段31，高压放 电电极32设置于静电除尘段31，高压放电电极32设置为对待净化空气进行净化。高压放电电极32包括间隔设置的两个放电极板。静电除尘是利用高压直流电场使空气中的气体分子电离，产生大量的电子和离子，在电场力的作用下向两级移动，在移动的过程中碰到气流中的粉尘和细菌，使气流中的粉尘和细菌成为荷电，荷电颗粒在电场力的作用下，向与自身电荷相反的放电极板运动；在电场力的作用下，空气中的自由离子同样要向两极移动，电压越高，电场强度就越高，离子的运动速度越快。由于离子的运动，两个放电极板间形成了电流。当电压升高到一定数值后，两个放电极板附近的离子获得较高的能量和速度，创击空气中的中性原子时会分解成为正、负离子，就是所谓的空气电离，称为电晕放电，空气成了导体，高强电压蒱获附带细菌颗粒和PM2.5的颗粒，以实现除尘。通过风机14循环汽车尾气和大气雾霾等待净化空气，达到了净化目的。但是静电除尘对空气中有害气体净化能力有限。
请参见图6，图6是负离子大气净化路灯结构示意图。该除霾式路灯的空气净化装置包括负离子生成芯片34，灯杆1的内部设有负离子净化段33，负离子生成芯片34设置于负离子净化段33，负离子生成芯片34设置为对待净化空气进行净化。运行时由负离子净化段33中的负离子生成芯片34模拟大自然原理释放等同大自然生态级别的负离子，这些负离子粒径小，活性高，自然扩散性强，无需借助风机外吹，就可以扩散至4-5米的距离，负离子从出风口15排出，对空间内的PM2.5等颗粒物进行有效的的净化。由于需要净化马路两旁的汽车尾气和大气雾霾，在一实施例中，通过配置风机增大负离子的扩散净化距离，本实施例配置风机14，以增加除霾式路灯净化面积。
请参见图7，图7是三元催化大气净化路灯结构示意图。该除霾式路灯的空气净化装置包括三元催化装置36，灯杆1的内部设有三元催化净化段35，三元催化装置36设置于三元催化净化段35，三元催化装置36设置为对待净化空气进行净化。三元催化通过氧化和还原化学反应作用，将汽车尾气和大气雾霾中的颗粒物转变为无害的二氧化碳、氮气和水。其中，三元催化剂是由贵金属铂、铑、钯并由载体制成。
