Description

震荡与除气泡结构及超声波液体浓度测试装置 技术领域
本公开涉及浓度测试装置技术领域，例如涉及一种震荡与除气泡结构及超声波液体浓度测试装置。
背景技术
柴油发动机以较高的马力在各行各业得到了广泛的应用。相对于汽油发动机而言，柴油在缸体内的高温作用下，生成氮氧化物，造成氮氧化物排放量高的问题，一直困扰产业界。由于人们对于环保要求的逐年提高，世界各国相继立法规定了发动机的排放标准，推动着各国发动机厂家对于尾气的处理技术的研究。
目前，我国已经强制使用国IV标准的发动机，并且配合相应的尾气处理技术。其中在全球起主导作用的技术路线是选择性催化还原(Selected Crystal Reduction，SCR)和排气再循环(Exhaust Gas Recirculation，EGR)+柴油颗粒过滤器(Diesel Particulate Filter，DPF)技术，其中又以SCR最为成熟与普遍。中国国内几家大的发动机厂家均选用了SCR系统这一技术路线，它是利用化学物质对于发动机尾气排放物质进行反应，进而生成对人体无害的物质。尿素或基于尿素的溶液经常被用在汽车应用中来减少汽车尾气中的有害物质排放，其中有害物质的主要的成分就是氮氧化物。化学反应方程式：NO X+NH 3→N 2+H 2O(N 2和H 2O是自然界空气中无害的物质)。
SCR系统包括尿素罐装载着柴油机尾气处理液和SCR催化反应罐。SCR系统的运行过程是：当发现排气管中有氮氧化物时，尿素罐自动喷出柴油机尾气处理液，柴油机尾气处理液和氮氧化物在SCR催化反应罐中发生氧化还原反应，生成无污染的氮气和水蒸气排出。
随着国四标准或者更高汽车尾气排放标准的全面执行，所有重型商用车必须按照SCR系统或者等同排放后处理装置，而国内绝大部分主机厂选择SCR系统，因而必须使用车用尿素。尿素使用过程中必须保持一定的浓度范围，才可以充分地将尾气中的氮氧化物转化为水和氮气。车用尿素溶液中尿素浓度的过高，会发生反应不充分，带来二次NH 3污染；尿素浓度过低，则达不到排放标准。
今后，随着配合车载诊断系统(On-Board Diagnostic，OBD)强制执行，在排放不达标、不装载柴油机尾气处理液、纯度不够或质量伪劣时，车辆会被限制扭矩，甚至限制启动，都会发生车辆发动机自动减速。同时，质量伪劣的柴油机尾气处理液会污染SCR催化反应罐中的催化剂，造成严重后果。因此，随着国六的实施，尿素浓度超声波液体浓度测试装置成为强制执行部件。
相关的测量液体浓度的超声波液体浓度测试装置，通过超声波发生装置、超声波接受装置以及超声波液体浓度测试装置控制系统的协同，可以实时地确定超声波液体浓度测试装置所在腔体内的溶液的浓度或者质量。但是，该装置无法在测量过程中消除影响测量精度的因素。例如，汽车运行过程中探头受到振动冲击造成的瞬时冲击过大，探头损坏或寿命降低，被测液体温度较高或者添加液体造成的气泡附着于超声发生与接受面等。探头受到的冲击大，会造成被测声波偏移较大的问题；气泡会造成超声信号的大幅衰减；进而造成声波偏移与信号衰减，都带来浓度测量不准确问题。因此，相关的超声波液体浓度测试装置测量得到的尿素液浓度测量结果精度不高、可靠性低。
