具体实施方式
下面结合附图和具体实施例对本发明作进一步说明，以使本领域的技术人员可以更好地理解本发明并能予以实施，但所举实施例不作为对本发明的限定。
参照图1-4所示，一种燃料电池汽车尾气检测装置，包括箱体9，所述箱体9上设有进气管、油水分离器1、过滤组件3、氢气检测组件7以及空气泵16，所述进气管与所述油水分离器1连接，所述油水分离器1与排水组件连接，所述油水分离器1将尾气内的水分从排水组件排出，所述油水分离器1通过第一管与过滤组件3连接，所述过滤组件3将尾气中的杂质进行过滤，所述过滤组件3通过第二管与氢气检测组件7连接，所述氢气检测组件7通过第三管与空气泵16连接，所述空气泵16出风端与出气管连接；
还包括泄压排气管，所述泄压排气管与第二管相通，所第二管上设有一支 管，所述支管上设置有压力传感器5，所述泄压排气管的出气口处设置有用于启闭出气口的安全阀6，当压力传感器5检测到的系统压力大于氢气检测组件允许的范围值时，安全阀6自动开启进行泄压。
本发明采用油水分离器1将尾气内的水分从排水组件排出，过滤组件3将尾气中的杂质进行过滤，避免汽车尾气中含有的大量水分和灰尘等杂质影响气体检测的准确性，有效确保后续氢气检测组件7测试精度不受影响；为了保证检测装置的测量精度，压力传感器5可对检测尾气压力进行实时检测和反馈，确保装置使用寿命及测试精度，当管路内压力值超过尾气检测允许值，安全阀6打开进行泄压，从而保证流量在一定范围，进一步保证检测精度。
还包括标气检测组件4，所述标气检测组件4包括检测管以及检测接口，所述检测管与第二管相通，所述检测接口设置在所述检测管上，所述检测接口与外部校调设备连接，所述外部校调设备对所述氢气检测组件7进行校调。
传感器的精度会随着时间的推移，精度会产生一定的偏差。因此，隔一段时间就需要对氢气检测部件校调。若将部件从系统中拆除再单独进行校调对使用者会非常的不方便。本发明提出增加标气检测接口以供对氢气检测组件7的校调，极大地提高检测精度以及校调便捷性。
所述箱体9内设置有加热丝15、温度传感器12以及风扇，所述箱体9上设有支架，所述支架上设置有温度传感器12，所述箱体9上开设有通孔，所述通孔上设置有风扇。
所述箱体9包括外箱13和内箱14，所述外箱13与所述内箱14之间设置有绕线槽，所述加热丝15设置在所述绕线槽上，所述外箱13与所述内箱14之间设置有导热胶。
尾气检测装置的工作环境一般都是在室外。检测装置受环境温度的影响比较大。当环境温度低于水溶液的结冰点时，油水分离器1以及排水组件会产生 结冰现象。影响装置功能的实现。因此，整套系统内置箱体9是恒温箱，从而减少环境温度对装置的影响。
外箱13与内箱14之间的加热丝15和风扇可对整体装置进行温度调控，可满足客户不同环境测试要求，提高了测试的可靠程度，取样速度也显著加快，检测范围更加全面，通过不同温度对尾气进行检测，提高检测的准确性。
所述排水组件包括蓄水容器2、进水管21以及出水管22，所述进水管21一端与油水分离器1连接，另一端插设在所述蓄水容器2内，所述出水管22穿设在所述蓄水容器2底部，所述出水管22的入水端高度高于所述进水管21的出水端。
所述油水分离器1与所述蓄水容器2中液位之间的距离L大于400㎜。
所述蓄水容器2内设置有初始水位H，所述初始水位的高度大于所述进水管21的出水端的高度H1，且低于出水管22的入水端高度H2。
由于燃料电池发动机的特殊性，它排放的尾气湿度接近100％RH，尾气经过油水分离器1过滤后，蓄水容器2会积存大量的水，因此，水需要及时的排出，否则水会倒灌至管路中，损坏部件，因此要求排水管路需要常开。
另外，蓄水容器2中保持的水量不能过少、蓄水容器2与油水分离器1之间的距离L也要大于一定值，因为管路与外部环境存在压差，蓄水容器2中的水或者空气会被吸入管路中，从而稀释标气乃至损坏部件。
本发明利用蓄水容器2内的初始水位的水压隔绝外界大气进入系统管路，
同时保证蓄水容器2中的水位H大于(H1+t)mm(条件：蓄水容器2直径Dmm，管路直径dmm满足{(D/d)^2}*t≥400)，本实施例较优的方案为所述蓄水容器2中的水位H大于H1+5mm(条件：蓄水容器2直径100mm，管路直径10mm)。油水分离器1与蓄水容器2之间的距离L要大于400mm。从而保证有水能够吸 入管路并形成一定的压差。
当检测装置工作时，进水管21与外部大气压之间形成一定的压差，蓄水容器2中的水被吸入进水管21。当外部大气压与水压达到平衡时，进水管21中的液位将保持恒定。特别地，当尾气经过油水分离器1，水被分离出来后会经过进水管21流至蓄水容器2中，当蓄水容器22中的水位大于H2时，蓄水杯中的水经过出水管22道排出。
氢气检测组件7与工控机10电性连接，所述工控机10上设置有启动按钮、显示屏以及警示灯。
氢气检测组件7检测到的数据通过CAN通信一方面能够发送到工控机10，进行氢气浓度的实时显示。另外，也能发送到整车系统11，为燃料电池发动机计算效率提供数据支持。
所述氢气检测组件7包括第一传感器和第二传感器，所述第一传感器为高量程低精度传感器，所述第二传感器为低量程高精度传感器。
氢气检测时采用先使用高量程低精度传感器进行检测，在通过低量程高精度传感器检测，可极大地提高检测准确性，保证测试结果的可靠性。
本发明还包括蓄电池8，所述油水分离器1、过滤组件3、氢气检测组件7、空气泵16、加热丝15、温度传感器12、风扇标气检测组件4以及工控机10电性连接，所述箱体9上设置有电源开关17，所述电源开关17与所述蓄电池8电性连接。
使用时，按下设备的电源开关17，工控机10开启，测试界面打开，测试界面见附图3。系统进行自检，温度传感器12上报箱体9温度数据给工控机10，工控机10判断是否需要对箱体9进行加热保温。当温度达到要求范围(≥10℃)后，测试前的准备工作完成，界面准备灯亮绿灯，界面启动按钮变亮。
按下电源开关17，蓄电池8给氢气检测组件7以及空气泵16通电，空气泵16启动，从而管路与外部环境形成压力差，燃料电池汽车尾气被吸入测试机台管路，完成气体采样。采样气体首先经过油水分离钻进进行干燥处理，分离出来的水通过进水管21进入蓄水容器2，干燥后的尾气经过过滤器组件去除气体中的大颗粒物杂质。经过干燥及过滤的尾气通过管路输送到氢气检测钻进中，检测尾气中所含的氢气浓度值经过CAN通信上传至工控机10以及整车系统11完成数据的上传，完成在界面上显示时间-氢气浓度曲线。最后，检测后的气体通过出气管排出。
当检测气体的氢气浓度值大于设定值时，工控机10上的报警灯亮起。
以上所述实施例仅是为充分说明本发明而所举的较佳的实施例，本发明的保护范围不限于此。本技术领域的技术人员在本发明基础上所作的等同替代或变换，均在本发明的保护范围之内。本发明的保护范围以权利要求书为准。
