Description

一种列车及其压缩气体处理设备及方法
本申请要求于2017年12月20日提交中国专利局、申请号为201711387396.X、发明名称为“一种列车压缩气体处理设备及方法”、以及于2017年12月20日提交中国专利局、申请号为201721800116.9、发明名称为“一种列车压缩气体处理设备及列车”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及列车压缩气体使用技术领域，特别涉及一种列车及其压缩气体处理设备及方法。
背景技术
随着我国在动车、高铁领域的不断发展，乘坐的人次和开设的车次也越来越多，因为人们都在追求着更加便利、更加快捷以及更加舒适和安全的出行方式，因此，如何在保证高铁、动车安全性能的基础上，尽可能的提高便利、舒适性是本领域技术人员不断研究的方向。
我们乘坐的高铁或动车，不仅设置有电子制动设备，也设置有备用的气动制动设备，既然是气动的制动设备，其使用的是具有一定气压的压缩气体。而在列车正式使用前，都需要经过各种测试，通常在列车正常行驶时，是利用车载空压机来进行气体的压缩，但在测试时出于其它设备的考虑，空压机的供电暂不正常，即在测试时空压机无法正常工作。
为解决上述技术缺陷，现有技术采用由外部供给具有一定气压的压缩气体，并将该压缩气体直接通入列车上某个气体传输管路中，往往由于通入的压缩气体的气体质量不达标，会对流经的气体传输管路或流经元器件造成不好的影响，而在外部增设气体处理设备的成本又过高。
所以，如何提供一种无需在外部增设气体处理设备、充分利用车载设备对输入的压缩气体进行处理的列车压缩气体处理设备是本领域技术人员亟待解决的问题。

具体实施方式
本申请的核心是提供一种列车压缩气体处理设备及处理方法，通过在合适的位置设置压缩气体的外输入口，先后经过过滤装置和干燥装置对输入的压缩气体进行处理，以使经过处理后的压缩气体符合预设气体质量要求和含水量低至预设比例。能够充分利用车载设备对输入的压缩气体进行处理，无需在外部增设压缩气体处理设备，减少测试和运维成本、延长各相关元器件的使用寿命。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然， 所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。
以下结合图1至图4详细描述本申请实施例提供的列车压缩气体处理设备的具体实现方式。其中，图1为本申请实施例所提供的一种列车压缩气体处理设备的设置示意图；图2为本申请实施例所提供的一种外输入口的设置示意图；图3为本申请实施例所提供的另一种外输入口的设置示意图；图4为本申请实施例所提供的一种过滤装置的结构流程示意图。
该列车压缩气体处理设备具体包括：
外输入口10，用于接收外部输入的压缩气体；
在本申请中，该外输入口10用于接收由列车外部的进行气体压缩操作后得到的具有一定气压的压缩气体。由于在列车测试过程中，无法启用车载空压机在列车上执行该气体压缩操作(电压不足)，但又需要进行压缩气体在列车内的测试工作，故一般采用外部的空压机完成这一过程，但通常仅进行压缩操作得到的压缩气体未达到列车正常使用的要求，而在测试环境下增设气体处理设备会显著提升测试和运维成本。
故本申请利用设置于合适位置的外输入口10，即该外输入口10位于后续车载气体处理设备的前端，能够充分利用车载气体处理设备的固有硬件性能，因为无论如何一定会在列车上设置有车载的气体处理设备。而且不能随便在列车上找一个气体传输管路20的入口，因为在不经过气体处理设备的处理之前，不符合要求的压缩空气不仅无法很好的使用，还有可能对其它元器件造成损伤。
例如，压缩气体中可能携带有固体小颗粒和其它杂质，同时也不确定该压缩气体中水分的含量，而较高水分含量的气体很容易使不耐腐蚀的元器件生锈，从而使得这些元器件性能下降甚至损坏。
可选的，外输入口10可以设置于列车中预设车厢的车体表面，以便测试时通入，因为在常见的8车厢列车中，可能只需设置一套压缩气体处理设备，该设备具体设置于哪节车厢，可以根据实际情况灵活选择。
进一步的，还可以设置多个外输入口10，例如在该车厢车体表面的左右两侧各设置一个，也可以统一设置在一侧，而是否需要设置更多外输入口10，可以根据实际情况结合特殊要求灵活考虑和选择。
可选的，外输入口10的输入端朝向斜上方，与水平面存在预设倾角。即外输入口10的朝向可以如图2所示，即与平行于水平面的车体外壳水平面存在角度为α的倾角，也可以简单的垂直或平行于车体外壳水平面。存在一个倾角的方案区别于垂直或平行的方案，好处在于，不至于超出车厢顶部太高，也不至于延伸出车厢宽度太远。
考虑到这是设置在车体外壳表面的一个装置，而列车可能会在多种天气状况下行驶，如图2所示的方案易在雨雪天气时从外输入口10进入雨水，从而伴随着列车的运动进入后续的气体传输管路20，这样容易存在危险。因此，可以设置外输入口10的输出端与气体传输管路20的输入端旋转连接，即其输入端能够相对于气体传输管路20的输入端旋转至朝向斜下方的位置。即该外输出口10可以逐渐从图2所示的朝向旋转至图3所示的朝向，由斜向上的朝向改变至斜向下的朝向，这样一来就可以很好的避免易进雨水的问题。
气体传输管路20，与外输入口10相连，用于传输压缩气体；
该气体传输管路20的主要任务是将从外输入口10进入的外部压缩气体通过自身传输至车载压缩气体处理设备，同时也是一个缓冲装置，以防特殊情况下从外输入口进入的危险物。进一步的，还可以在该气体传输管路20上设置一系列传感器和阀门，传感器可以包括用于测量外部输入的压缩空气的气压大小的气压传感器等，阀门则可以作为一个手动控制通断的安全装置，若万一气体传输管路20的哪个部位突然断裂，可以通过阀门来减少损害。这些装置都可以灵活添加，并不做具体限定。
过滤装置30，与气体传输管路20的输出端相连，用于滤除压缩气体中含有的杂质，直至过滤后的压缩气体的质量达到预设气体质量要求。
为实现过滤装置30的目的，在一个实施例中过滤装置30可以如图4所示，具体包括：
过滤器31，与气体传输管路20的输出端相连，用于滤除压缩气体中含有的杂质；
气体质量检测器32，与过滤器31的输出端相连，用于检测过滤后的压缩气体的质量是否达到预设气体质量要求，并根据检测结果生成并发送相应的导向信号；
导向装置33，用于根据接收到的导向信号，与过滤器返回管34或干燥传输管35的输入端相连，其输入端与气体质量检测器32的输出端相连，其第一输出端331与过滤器返回管34的输入端相连，其第二输出端332与干燥传输管35的输入端相连；
过滤器返回管34，与过滤器31的输入端相连，用于传输未达到预设气体质量要求的压缩气体；
干燥传输管35，与干燥装置40的输入端相连，用于传输达到预设气体质量要求的压缩气体。
具有两种工作模式：
在第一工作模式下，导向装置33接收到将未达到预设气体质量要求的压缩气体导向过滤器31的导向信号，第一输出端331与过滤器返回管34相连，并断开第二输出端332与干燥传输管35的连接；
在第二工作模式下，导向装置33接收到将达到预设气体质量要求的压缩气体导向干燥装置40的导向信号，第二输出端332与干燥传输感35相连，并断开第一输出端331与过滤器返回管34的连接。
即通过图4所示的导向装置搭配可选择连接的两条管路，分别将未达到预设气体质量要求的压缩气体传回过滤器31和将达到预设气体质量要求的压缩气体传向干燥装置40，以此达到完成过滤器的过滤目的，得到达到预设气体质量要求的压缩气体。
干燥装置40，与过滤装置30相连，用于干燥达到预设气体质量要求的压缩气体，直至干燥后的压缩气体的水分比率降低至预设比率；
干燥装置40的目的与过滤装置30的目的大体相同，区别于过滤装置30对杂质的过滤以达到预设气体质量要求，干燥装置40在于将达到预设气体质量要求的压缩气体中含有的水分降低至预设比例，以防止对流经的其它元器件造成损伤。
相应的，也可以应用如过滤装置30大体一致的装置，即适应性的选用： 干燥器、水分含量检测器、导向装置、干燥器返回管以及内输出口传输管等装置，至于在能够实现相同目的的条件下选用何种型号的元器件，并不对此进行限定，可以根据实际情况进行灵活选择，以最合适的元器件来实现功能。
更进一步的，本实施例只简单论述了存在过滤装置30和干燥装置40的情况，不同车型、不同行驶环境下的列车可能会适应性的增加或减少某些气体处理设备，且具体以何种方式与其它元器件建立连接，并不进行具体限定，在无需付出创造性劳动的前提下，应均在本申请的保护范围内。
内输出口50，与干燥装置40相连，用于输出水分比率降低至预设比率的压缩气体。
进一步的，该列车压缩气体处理设备还可以包括：
列车执行机构，与内输出口50相连，用于利用输出的压缩气体执行各种列车制动操作。
以上各功能装置应用在实际列车中，可以得到如图8所示的气路原理图，该气路原理图即是包括上述各功能装置的一种列车压缩气体处理设备。
图中的两侧的为两个外输入口，用于当列车停放在车库或停车场时，通过这两个外输入口外接压缩气体风源向列车提供压缩空气。.09和.10为两个球阀，在无需使用外接风源时通常处于关断位置，在需要使用外接风源时将其置于导通位，.04为列车车载使用的双塔干燥器，.08为车载过滤器，其它均是一些附属设备的型号和参数，在此不再赘述。
本申请旨在利用设置在车载压缩气体处理设备附近的外输入口，承接只有气压达标的外接风源，能够充分利用车载压缩气体处理设备，使得进入列车内部的压缩气体质量得到的保证，有效避免了外接风源污染列车内部元器件现象的出现，同时也无需地方设置成本高昂的压缩气体处理设备。
基于上述技术方案，本申请实施例提供的列车压缩气体处理设备，通过在合适的位置设置压缩气体的外输入口，先后经过过滤装置和干燥装置对输入的压缩气体进行处理，以使经过处理后的压缩气体符合预设气体质量要求和含水量低至预设比例。能够充分利用车载设备对输入的压缩气体进行处理，无需在 外部增设压缩气体处理设备，减少测试和运维成本、延长各相关元器件的使用寿命。
以下结合图5，图5为本申请实施例所提供的一种列车压缩气体的处理方法的流程图。
为实现上述目的，本申请还提供了一种列车压缩气体的处理方法，应用于如实施例一所描述的列车压缩气体处理设备，包括：

本步骤建立在S302的判断结果为不处于该正常参数范围内的基础上，判定过滤装置30处于异常状态，并对过滤装置30进行维护。
本实施例旨在采集到的过滤装置的各种工作参数，并对各种工作参数与正常情况下这些工作参数应处于的正常范围做比较，若不处于正常范围，则认定该过滤装置的某些部分有可能已经出现一些问题，故应在重大故障发生前提前进行维护或更换。
相同的，也可以在干燥装置40上采用相同的方法来对干燥装置40的工作状态进行判定，并根据结果对干燥装置40进行维护，在此不再赘述。
