Description
技术领域
本发明涉及汽车尾气净化技术领域,具体是一种汽车尾气净化及余热回收一体化装置。
背景技术
在经济快速发展的大背景下,近年来中国汽车保有量保持在10%以上增幅,截至2015年10月底,我国机动车保有量为2.76亿辆,其中汽车1.69亿辆。众所周知,汽车在行驶的过程中会产生大量的有害气体,常以烟雾形式出现,其主要的污染物为碳氢化合物、氮氧化合物、一氧化碳、二氧化硫、醛、含铅化合物、及固体颗粒物等。现有汽车尾气排放标准不一,主要靠三元催化器、电喷、提高燃油标准等,来降低尾气排放。也有一些新的汽车尾气处理方法,如超声负氧离子处理、臭氧水雾喷净化等,但其安装不便,需要对汽车多部件进行改装,以满足其使用条件。
发明内容
鉴于以上所述现有技术的缺陷和不足之处,本发明要解决的技术问题在于提供一种汽车尾气净化及余热回收一体化装置,能对汽车尾气的余热进行有效回收,并为汽车尾气净化装置提供动力,其目的在于利用汽车尾气余热进一步净化汽车尾气。
本发明解决技术问题采用如下方案:
本发明为汽车尾气净化及余热回收一体化装置,包括变径排气管、热电转化装置、臭氧发生装置、负离子除烟雾装置和自动稳压模块。所述热电转化装置紧贴并固定在变径排气管上,且分布于上下表面。所述臭氧发生装置和负离子除烟雾装置分别位于变径排气管左右两侧,通过隔热材料与变径排气管接触。所述自动稳压模块为12V自动升降压稳压恒流模块,其输入端通过导线与热电转化装置连接,输出端与臭氧发生装置和负离子除烟雾装置连接。
所诉热电转化装置包括硅脂导热片、温差发电片、散热片和散热涡扇。所述硅脂导热片的一面直接与变径排气管接触,另一面与温差发电片接触,从而实现热量在两者之间均与传递,提高传热效率。所述散热片位于温差发电片上方,且在散热片上方添加散热涡扇进行强制散热。
所述臭氧发生装置包括高压脉冲发生器、臭氧发生管和气泵。所述高压脉冲发生器通过导线与臭氧发生管连接,在臭氧发生管内产生臭氧。所述臭氧发生管进气口与气泵连接,出气口与变径排气管连接并伸入排气管内,从而将产生的臭氧输送至排气管,与尾气中的一氧化氮、一氧化碳和二氧化硫等有害气体反应,达到净化尾气的目的。
所述负离子除烟雾装置包括负高压发生器和两个碳纤维毛刷,所述负高压发生器通过导线与两个碳纤维毛刷连接,所述碳纤维毛刷固定在变径排气管内壁上,通电后,碳纤维毛刷尖端产生的负高压电晕将在变径排气管内激发大量负氧离子,中和带正电荷的烟雾颗粒,使其沉降下来,达到除烟雾的目的。
进一步地,所述变径排气管内壁上添加翅片,以增大传热面积,从而提高热电转化效率。
本发明的有益效果是:
(1)本发明通过热电转化装置,巧妙地利用汽车尾气余热来净化汽车尾气,达到节能环保的目的。
(2)本发明采用臭氧和负离子两套净化装置,分别针对汽车尾气中的有害气体和烟雾颗粒,具有双重净化效果。
(3)本发明结构紧凑,一体化程度高,可直接串联在汽车排气管上使用,安装方便。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1A和图1B为本发明立体结构示意图。
图2为本发明剖视的内部结构示意图。
在附图中:1.变径排气管,2.热电转化装置,3.臭氧发生装置,4.负离子除烟雾装置,5.自动稳压模块,6.翅片,201.硅脂导热片,202.温差发电片,203.散热片,204.散热涡扇,301.高压脉冲发生器,302.气泵,303.臭氧发生管,401.负高压发生器,402.碳纤维毛刷。
具体实施方式
下面结合附图,将详细描述本发明的技术方案。
参见图1A、图1B和图2,本发明所述的汽车尾气净化及余热回收一体化装置,包括1.变径排气管,2.热电转化装置,3.臭氧发生装置,4.负离子除烟雾装置,5.自动稳压模块,6.翅片,201.硅脂导热片,202.温差发电片,203.散热片,204.散热涡扇,301.高压脉冲发生器,302.气泵,303.臭氧发生管,401.负高压发生器,402.碳纤维毛刷。
如图1A所示,所述热电转化装置包括硅脂导热片201、温差发电片202、散热片203和散热涡扇204。所述硅脂导热片201的一面直接与变径排气管1接触,另一面与温差发电片202接触,从而实现热量在变径排气管1和温差发电片202之间均匀传递,提高传热效率。所述散热片203位于温差发电片202上方,且在散热片203上方还添加散热涡扇204进行强制散热,进一步增大温差发电片202冷热面的温差,提高发电效率。
如图1A所示,所述臭氧发生装置包括高压脉冲发生器301、臭氧发生管303和气泵302。所述高压脉冲发生器301通过导线与臭氧发生管303连接,在臭氧发生管303内产生臭氧。所述臭氧发生管303进气口与气泵302连接,出气口与变径排气管1连接并伸入变径排气管1内,从而将产生的臭氧(具有极强的氧化性)输送至排气管,与尾气中的一氧化氮、一氧化碳和二氧化硫等有害气体发生氧化还原反应,将其转化为无毒气体,而未反应的臭氧又会在高温尾气下逐渐降解为氧气,从而达到净化尾气的目的。
参见图1B和图2,所述负离子除烟雾装置包括负高压发生器401和两个碳纤维毛刷402,所述负高压发生器401通过导线与两个碳纤维毛刷402连接,所述碳纤维毛刷402固定在变径排气管1内壁上。通电后,碳纤维毛刷402尖端产生的负高压电晕将在变径排气管1内激发大量负氧离子,来中和带正电荷的烟雾颗粒,使其失去电荷而沉降下来,随尾气落到地面变为灰尘,从而达到除烟雾的目的。
如图2所示,在变径排气管1内壁上下表面,添加沿尾气流动方向分布的翅片6来增大传热面积,以提高传热效率,其最终目的是为了提高尾气的热电转化效率。
本实施例中,自动稳压模块5具体是12V自动升降压稳压恒流模块,其主要作用是将温差发电片输出的变化的电压转化为稳定的12V输出,供给臭氧发生装置和负离子除烟雾装置使用。
本发明为汽车尾气净化及余热回收一体化装置,可直接串连到车辆的尾气排放管道上,可应用于不同的汽车,适应性高,能有效净化汽车尾气中的有害气体和烟雾颗粒,有利于改善空气质量。所以,本发明克服了现有技术中的种种缺点和不足,具有很好的推广价值。
以上对本发明实施例所提供的一种汽车尾气净化及余热回收一体化装置进行了详细介绍,对于本领域的一般技术人员,依据本发明实施例的思想,在具体实施方式及应用范围上均会有改变之处,综上所述,本说明书内容不应理解为对本发明的限制,凡依本发明设计思想所做的任何改变都在本发明的保护范围之内。
