Description

粉尘监测方法、系统及信号处理装置 技术领域
本发明涉及气固分离技术领域，具体而言，涉及可与气固分离过程配套的粉尘监测方法、粉尘监测系统以及粉尘监测系统的信号处理装置。
背景技术
为了对气固分离设备尤其是通过过滤部件拦截气流中的粉尘以实现气固分离(一般还会通过反吹控制部件对过滤部件进行周期性反吹以使粉尘从过滤部件上脱离从而恢复过滤部件的透气性)的气固分离设备(例如滤袋除尘器)的气固分离效率进行监测，可以在气固分离设备的净气输出侧安装粉尘检测部件，从而通过粉尘检测部件对气固分离设备输出的净气粉尘浓度进行测量，当发现气固分离设备输出的净气粉尘浓度升高到一定程度后，可以认为气固分离设备异常，这时往往需要对气固分离设备中的过滤部件进行检查，查找过滤部件是否存在具有可导致粉尘泄露的破损或者与密封部件之间的密封不良等过滤部件异常问题。
为了对气固分离设备的气固分离效率进行更有效的监测，需要选用适宜的粉尘检测部件。在公开号为CN107643149A、名称为“一种除尘器袋漏定位及故障诊断系统”的中国专利申请文件中提出用微电荷原理探测器(参见该专利申请文件说明书第4页、第[0041]段、第4行)作为粉尘检测部件。另外，该专利申请文件还提供了将反吹控制与粉尘检测部件配合运用从而实现不仅能够判断气固分离设备中过滤部件是否异常同时还能够从气固分离设备的众多过滤部件中将异常的过滤部件定位在一定范围内的技术，即异常过滤部件的定位技术。
工业上的气固分离系统常常包含多个分别作为气固分离单元的气固分离设备。通常，这样的气固分离系统的各气固分离单元的净气输出侧分别与同一汇流通道连接，从而通过该汇流通道将这些气固分离单元输出的净气汇集起来并集中向外输送。若需要对各气固分离单元的气固分离效率进行监测，目前采取的方法是分别在这些气固分离单元的净气输出口或者这些气固分离单元的净气输出口与汇流通道连接的净气输送通道上安装粉尘检测部件，总之就是要将粉尘检测部件设于汇流通道之前，从而确保各气固分离单元的净气输出侧都存在与之对应的粉尘检测部件。

下面结合附图和具体实施方式对本发明做进一步的说明。本发明附加的方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本发明的实践了解到。

具体实施方式
下面结合附图对本发明进行清楚、完整的说明。本领域普通技术人员在基于这些说明的情况下将能够实现本发明。在结合附图对本发明进行说明前，需要特别指出的是：
本发明中在包括下述说明在内的各部分中所提供的技术方案、技术特征，在不冲突的情况下，这些技术方案、技术特征可以相互组合。
此外，下述说明中涉及到的本发明的实施例通常仅是本发明的一分部实施例而不是全部实施例，因此，基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其他实施例，都应当属于本发明保护的范围。
关于本发明中术语和单位：本发明的说明书和权利要求书及有关的部分中的术语“包括”、“包含”、“具有”以及它们的任何变形，意图在于覆盖不排他的包含。本发明中的“气固分离”，是指气体与气体中固体颗粒物的分离。此外，本发明中的其他相关术语和单位，均可基于本发明相关内容得到合理的解释。
图1为本发明的粉尘监测系统的一个实施例中信号获取部与信号处理部连接示意图。如图1所示，本发明的粉尘监测系统包括信号获取部110、信号传输部120和信号处理部130；其中，信号获取部110用于通过分别位于不同气固分离单元净气输出侧的粉尘检测部件111获取目标信号，信号传输部120用于输送由信号获取部110获取的目标信号，信号处理部130用于接收由信号传输部120输送的目标信号、进行信号处理并输出监测结果。
图2为本发明的粉尘监测系统的一个实施例中粉尘检测部件部署示意图。结合图1和 图2所示，本发明的粉尘监测系统中的信号获取部110的粉尘检测部件111具体部署在同时与所述不同气固分离单元210的净气输出侧连接的汇流通道220上并分别设置在该汇流通道220上各个用于与所述不同气固分离单元210的净气输出侧连接的连接点之后。
其中，所述不同气固分离单元210包括至少两个一般为三个以上气固分离单元210。这些气固分离单元210可以是采用任何一种气固分离手段实现气固分离作用的气固分离单位。目前已知的气固分离手段很多，常见的有重力除尘、旋风除尘、电除尘、滤袋除尘、陶瓷滤芯除尘、金属滤芯除尘等等。
所述汇流通道220的常规结构为横截面为圆形或矩形的净气总管。但是，由于气固分离系统设计的多样性，汇流通道220也可能被设计为非常规结构。例如，在一个包括多个滤袋除尘器的气固分离系统中，每一个滤袋除尘器均作为一个气固分离单元，在这些滤袋除尘器的一侧设有一个横截面为矩形并向前延伸的通道，这些滤袋除尘器沿着该通道的长度方向间隔排列在该通道的外侧，该通道内有一块隔板将通道分别上下两层空间，下层空间作为原气输入通道与各滤袋除尘器的原气输入侧连通(“原气”是指待气固分离处理的气体)，而上层空间则作为所述汇流通道220与各滤袋除尘器的净气输出侧连通，此外，该隔板相对于水平面还具有一定的倾斜角度，从而使原气输入通道的横截面面积沿原气输入方向由大变小、汇流通道220的横截面面积沿净气输出方向由小变大。显然，上述汇流通道220就属于一种非常规结构的汇流通道。
前文中还采用了“上述信号获取部110的粉尘检测部件111具体部署在同时与所述不同气固分离单元210的净气输出侧连接的汇流通道220上并分别设置在该汇流通道220上各个用于与所述不同气固分离单元210的净气输出侧连接的连接点之后”的描述或限定。这样的描述或限定可以理解为：在汇流通道220上任意相邻连接点(具体指与气固分离单元210连接的连接点)之间都部署有粉尘检测部件111；但是，该汇流通道220上任意相邻连接点之间并非只能部署一个粉尘检测部件111。
作为汇流通道220上任意相邻连接点之间部署超过一个粉尘检测部件111的一个例子，为：出于冗余设计的考虑，在汇流通道220上各相邻连接点之间部署了两个粉尘检测部件111。这时，可认为这两个粉尘检测部件均与一气固分离单元210对应。
此外，还存在这样的可能，即汇流通道220上任意相邻连接点之间看起来部署了两个以上粉尘检测部件，但它们实际上仍为一个粉尘检测部件。例如，若某粉尘检测部件需要结合两个以上的传感器探头才能获得目标信号，这时，即使这两个传感器探头被分别安装在了汇流通道220上任意相邻连接点之间的不同部位，但是，这两个传感器探头实质上仍 然属于同一个粉尘检测部件。
本发明的粉尘监测系统中，粉尘检测部件111优选采用以获取的气流中的粉尘颗粒物在经过该粉尘检测部件的感应探头时在该感应探头上产生的电信号为目标信号的粉尘检测部件。从目前已知的气固分离领域粉尘检测技术来看，上述这类粉尘检测部件检测精度较高，并且较为适合在本发明的粉尘监测系统中应用。本说明书“背景技术”部分引用的一篇现有技术所采用的微电荷原理探测器，也属于这类粉尘检测部件。
上述这类粉尘检测部件主要可分为几种具体的类型：一种是以获取气流中的粉尘颗粒物撞击所述感应探头时在该感应探头上产生的撞击电流信号为目标信号的粉尘检测部件；另一种以获取气流中的粉尘颗粒物从所述感应探头旁边掠过时在该感应探头上产生的感应电流信号为目标信号的粉尘检测部件；还有一种以同时获取上述撞击电流信号和感应电流信号为目标信号的粉尘检测部件。
针对上述几种粉尘检测部件，建议可以从美国奥本费尔升有限公司(英文名：Auburn FilterSense LLC)制造的商品名称为TRIBO的粉尘检测部件中选用。奥本费尔升有限公司的前身为奥本系统有限公司(英文名：Auburn system LLC)，是上述几种粉尘检测部件及配套技术开发和应用的先驱和优秀供应商。
当然，粉尘检测部件111并非只能采用以获取的气流中的粉尘颗粒物在经过该粉尘检测部件的感应探头时在该感应探头上产生的电信号为目标信号的粉尘检测部件。尽管不同粉尘检测部件的原理有所不同，但是，为了提高粉尘检测的准确度，提升被检测气固两相流的流动均匀性以及粉尘分布的均匀性总是有利的。
本发明的粉尘监测系统中，信号传输部120可以采用所有适用的数据传输手段。但为了尽可能的避免干扰，建议通过抗干扰的信号线将信号获取部110的信号输出端口与信号处理部130的信号输入端口连接。
本发明的粉尘监测系统中，信号处理部130既可以由独立且分别与各粉尘检测部件111对应连接的信号处理单元组成，也可以是一个同时与各粉尘检测部件111连接的信号处理装置，该信号处理装置一般被配置成具有必要硬件和软件的用户终端。
此外，本发明的粉尘监测系统的信号获取部110、信号传输部120和信号处理部130还可以集成为一体，或者部分集成为一体。
本发明的粉尘监测系统用于执行这样的粉尘监测方法，该方法包括：信号获取部110通过分别位于不同气固分离单元210净气输出侧的粉尘检测部件111获取目标信号；信号传输部120输送由信号获取部110获取的目标信号；信号处理部130接收由信号传输部 120输送的目标信号、进行信号处理并输出监测结果。
一般而言，本发明的粉尘监测方法中所述信号处理部130的信号处理工序包括至少根据信号传输部120提供的目标信号并通过预设策略来判断所述不同气固分离单元210中各气固分离单元210输出的净气粉尘浓度是否出现异常状态的第一处理。
当通过所述第一处理将不同气固分离单元210中的至少一个气固分离单元210输出的净气粉尘浓度判断为异常状态时，信号处理部130输出的监测结果可表达为可指向相应气固分离单元210异常的通知。所述通知可以是指向相应气固分离单元210异常的报警或提示。
若所述不同气固分离单元210中各气固分离单元210均为通过过滤部件拦截气流中的粉尘以实现气固分离、通过反吹控制部件对过滤部件进行周期性反吹以使粉尘从过滤部件上脱离的气固分离单元(如滤袋除尘单元、陶瓷滤芯除尘单元等)，鉴于当气固分离单元210中的过滤部件存在异常的情况下进行反吹时会导致净气粉尘浓度显著提高这个在本说明书背景技术中引用的CN107643149A中已经提到的现象，在此基础上，所述第一处理可至少根据反吹控制部件提供的用于表征各气固分离单元是否存在反吹行为的信息和信号传输部提供的目标信号并通过预设策略来判断所述不同气固分离单元中各气固分离单元基于自身反吹而引发的净气粉尘浓度变化是否出现净气粉尘浓度异常状态。
当通过所述第一处理将不同气固分离单元中的至少一个气固分离单元基于自身反吹而引发的净气粉尘浓度变化判断为净气粉尘浓度出现异常状态时，所述信号处理部输出的监测结果还可表达为可指向相应气固分离单元中过滤部件异常的通知。
本发明的粉尘监测系统和粉尘监测方法，由于将信号获取部110的粉尘检测部件111部署在了同时与所述不同气固分离单元210的净气输出侧连接的汇流通道220上并分别设置在该汇流通道220上各个用于与所述不同气固分离单元210的净气输出侧连接的连接点之后，因此，在汇流通道220上任意相邻连接点之间都部署有粉尘检测部件111并且任意粉尘检测部件111都与该粉尘检测部件111所属的相邻连接点中上游的那个连接点连接的气固分离单元210对应，从而可使所述不同气固分离单元210中各气固分离单元210输出的净气中的粉尘状况(如粉尘浓度变化)被对应的粉尘检测部件111获取，最后实现对粉尘状况的监测。
另外，由于汇流通道220中气流运动更为规则，且汇流通道220中粉尘均匀性较高，将粉尘检测部件部署在汇流通道220上容易获取更为真实的目标信号，提高粉尘检测的准确度。
而根据本说明书背景技术部分记载的内容可知，现有技术是将粉尘检测部件设于汇流通道之前。但本发明的发明人发现：气固分离单元至汇流通道之间的净气输送通道长度一般较短且存在变向，导致气流运行不规则，另外，净气中未被分离出的粉尘在气固分离单元至汇流通道之间的净气输送通道中无法充分扩散，导致气固分离单元至汇流通道之间的净气输送通道中的粉尘分布不均匀，因此，若将粉尘检测部件部署在气固分离单元至汇流通道之间的净气输送通道上，可能导致检测准确度较低。
下面结合图1、图2、图4和图5，对本发明的粉尘监测系统的一个实施例以及应用该实施例的粉尘监测方法进行具体说明。
如图2所示，气固分离系统200包括排成一排的多个气固分离单元210，其中每个气固分离单元210即为一个滤袋除尘器(带有反吹功能)。
由这些气固分离单元210组成的气固分离部的一侧具有一个沿这些气固分离单元210的排列方向直线延伸并作为汇流通道220的净气总管，各气固分离单元210(按汇流通道220的气流方向，各气固分离单元210依次为气固分离单元210A、气固分离单元210B、气固分离单元210C……)分别通过各自的净气输送通道230与汇流通道220连接。
各净气输送通道230的一端与对应的气固分离单元210的净气输出端连接、另一端与汇流通道220连接(连接处即为汇流通道220上各个分别用于与这些气固分离单元210的净气输出侧连接的连接点)。此外，各净气输送通道230上均设有阀门240。
参见图2所示，上述这些气固分离单元210以及与这些气固分离单元的净气输出侧连接的连接点沿汇流通道220的气流方向依次间隔排列。
上述气固分离系统200的基本工作过程为：
首先，原气(“原气”是指待气固分离处理的气体)分别进入各气固分离单元210并通过滤袋进行过滤，过滤后的净气经过各净气输送通道230(此时各净气输送通道230上的阀门240均打开)后进入汇流通道220中，然后通过汇流通道220输出。
然后，依次对各气固分离单元210进行离线清灰。其中，对一个气固分离单元210进行离线清灰包括：
先在反吹控制部件的指令下关闭气固分离单元210A的净气输送通道230上的阀门240；
然后通过反吹控制部件指令反吹装置向气固分离单元210A的中通入反吹气流，从而通过反吹气流对滤袋进行反吹以使粉尘从滤袋上脱离；
反吹结束后，反吹控制部件指令反吹装置停止向气固分离单元210A的中通入反吹气 流；
然后反吹控制部件再指令气固分离单元210A的净气输送通道230上的阀门240打开；
最后，气固分离单元210A恢复原先的过滤状态。
此后，依次对气固分离单元210B、气固分离单元210C……执行与上述操作相同的操作。
如图1、图2所示，在上述气固分离系统200上安装粉尘监测系统，该粉尘监测系统包括信号获取部110、信号传输部120和信号处理部130；其中，信号获取部110的多个粉尘检测部件111部署在图2中的汇流通道220上并分别设置在该汇流通道220上各个用于与各个滤袋除尘器的净气输出侧连接的连接点之后。
按汇流通道220的气流方向，各粉尘检测部件111依次为粉尘检测部件111A、粉尘检测部件111B、粉尘检测部件111C……，其中，粉尘检测部件111A与气固分离单元210A对应，粉尘检测部件111B与气固分离单元210B对应，粉尘检测部件111C与气固分离单元210C对应，以此类推。
图4为本发明的粉尘监测系统的一个实施例中粉尘检测部件构造示意图。上述粉尘检测部件111均采用图4所示的粉尘检测部件。
该粉尘检测部件111是一种以获取气流中的粉尘颗粒物撞击所述感应探头时在该感应探头上产生的撞击电流信号为目标信号的粉尘检测部件。具体选用奥本费尔升有限公司(英文名：Auburn FilterSense LLC)制造的商品名称为TRIBO的粉尘检测部件。
如图4所示，粉尘检测部件111的感应探头插入汇流通道220中。
图5为本发明的粉尘监测方法的一个实施例的流程示意图。如图5所示，基于上述粉尘监测系统实施如下粉尘监测方法，该包括：
步骤S101:信号获取部110通过分别位于各气固分离单元210净气输出侧的粉尘检测部件111获取目标信号。
步骤S102：信号传输部120输送由信号获取部110获取的目标信号。
步骤S103：信号处理部130接收由信号传输部120输送的目标信号、进行信号处理并输出监测结果。
其中，步骤S103具体包括：
步骤S103A：根据信号传输部120输送的目标信号判断是否有气固分离单元210出现净气粉尘浓度异常状态。
针对此步骤，由于在汇流通道220上任意相邻连接点之间都部署有粉尘检测部件111 并且任意粉尘检测部件111都与该粉尘检测部件111所属的相邻连接点中上游的那个连接点连接的气固分离单元210对应(粉尘检测部件111A与气固分离单元210A对应，粉尘检测部件111B与气固分离单元210B对应，粉尘检测部件111C与气固分离单元210C对应，以此类推)，从而可使各气固分离单元210输出的净气粉尘浓度变化被对应的粉尘检测部件111获取，实现对净气粉尘浓度异常状态的监测。
显而易见，通过粉尘检测部件111A获得的目标信号可判断气固分离单元210A是否出现净气粉尘浓度异常状态。
而通过粉尘检测部件111B获得的目标信号可判断气固分离单元210B是否出现净气粉尘浓度异常状态。但需要指出的是：尽管气固分离单元210A若出现净气粉尘浓度异常状态会对粉尘检测部件111B获得的目标信号造成一定影响，但是，由于在汇流通道220中位于粉尘检测部件111B之前的管道内气固分离单元210A输出的净气与气固分离单元210B输出的净气发生了汇流，使得气固分离单元210A输出的净气中的粉尘被稀释，导致上述影响的效果降低，因此，就使得通过粉尘检测部件111B获得的目标信号判断气固分离单元210B是否出现净气粉尘浓度异常状态成为可能。
同理，通过粉尘检测部件111C获得的目标信号可判断气固分离单元210C是否出现净气粉尘浓度异常状态。
鉴于气固分离单元210与粉尘检测部件111的对应性以及粉尘检测部件111在汇流通道220上的部署方式，还可以通过附加手段来进一步确保根据信号传输部120输送的目标信号判断是否有气固分离单元210出现净气粉尘浓度异常状态的准确性。
上述的附加手段可以是：对某气固分离单元210输出的净气粉尘浓度是否出现异常状态的判断是通过对与该气固分离单元210对应的粉尘检测部件111所获取的目标信号以及在所述汇流通道220上位于与该气固分离单元210对应的粉尘检测部件111上游或/和下游的至少一个粉尘检测部件111所获取的目标信号进行关联判断后作出的。对此，将在本发明下一实施例中予以具体说明。
步骤S103B：当通过步骤S103A判断某气固分离单元210出现净气粉尘浓度异常状态时，根据反吹控制部件提供的用于表征气固分离单元210是否存在反吹行为的信息判断出现净气粉尘浓度异常状态的气固分离单元210是否进行了反吹。
该步骤中，信号处理部130需要接收反吹控制部件提供的用于表征气固分离单元210是否存在反吹行为的信息，从而判断出现净气粉尘浓度异常状态的气固分离单元210是否进行了反吹。
步骤S103C：当通过步骤S103B判断出现净气粉尘浓度异常状态的气固分离单元210进行了反吹时，根据反吹控制部件提供的与所述汇流通道220连接并用于向该汇流通道220输送净气的净气输送通道上的阀门240的启闭信息判断出现净气粉尘浓度异常状态的气固分离单元210所对应的阀门240是否开启。
根据反吹控制部件提供的与所述汇流通道220连接并用于向该汇流通道220输送净气的净气输送通道上的阀门240的启闭信息，如果出现净气粉尘浓度异常状态的气固分离单元210所对应的阀门240是在该气固分离单元210出现净气粉尘浓度异常状态之前的设定时间内开启，说明该气固分离单元210输出的净气粉尘浓度出现异常状态是由该气固分离单元210自身反吹而引发的。
步骤S103D：当通过步骤S103C判断出现净气粉尘浓度异常状态的气固分离单元210所对应的阀门240开启从而确定气固分离单元210输出的净气粉尘浓度出现异常状态是由该气固分离单元210自身反吹而引发后，信号处理部130输出监测结果，该检测结果表达为可指向出现净气粉尘浓度异常状态的气固分离单元210中过滤部件异常的通知。
下面结合图1、图3和图6，对本发明的粉尘监测系统的另一个实施例以及应用该实施例的粉尘监测方法进行具体说明。
如图3所示，气固分离系统包括排成一排的多个气固分离单元210(参见标号“210”的虚线框)，其中每个气固分离单元210包含两个过滤器211，每个过滤器211均为滤袋除尘器。
每个滤袋除尘器中安装有多组气固分离组件211A，每一组气固分离组件211A包括多个滤袋以及可同时对这些滤袋进行脉冲反吹清灰的反吹装置，每个滤袋除尘器中的多组气固分离组件211A按顺序先后进行脉冲反吹清灰。
由这些气固分离单元210组成的气固分离部的中间具有一个沿这些气固分离单元210的排列方向直线延伸并作为汇流通道220的净气总管，每个气固分离单元210的两个过滤器211均相对设置于汇流通道220的左右两侧。
所述汇流通道220上与任意一个气固分离单元210的净气输出侧连接的连接点包含分别与该气固分离单元210的两个过滤器211各自的净气输出侧对应连接的子连接点。各子连接点与对应的过滤器211之间的净气输送通道上均设有阀门240。
此外，汇流通道220沿其气流方向(即图3中从左向右的方向)通道横截面积逐渐增大(图中未示出)，以便使汇流通道220的通道横截面积随着更多净气的汇入而增大，从而将汇流通道220内的压力和流速维持在较为一致的范围内。
具体而言，为便于制造，所述汇流通道220分为不同管段，同一管段内的管道直径相同，不同管段的管道直径沿所述汇流通道的气流方向逐渐增大。其中，相邻管段之间结合处最好靠近汇流通道220上相邻两个分别与相邻气固分离单元210的净气输出侧连接的连接点之间的中间点，从而使管道直径变径位置尽可能远离所述连接点。
上述气固分离系统的基本工作过程为：
首先，原气分别进入各气固分离单元210的两个过滤器211并通过滤袋进行过滤，过滤后的净气经过各净气输送通道(此时各净气输送通道上的阀门240均打开)后进入汇流通道220中，然后通过汇流通道220输出。
然后，依次对各气固分离单元210进行在线清灰。其中，对一个气固分离单元210进行在线清灰包括：
先通过反吹控制部件指令汇流通道220最上游的气固分离单元210中的其中一个过滤器211的其中一组气固分离组件211A的反吹装置向该气固分离组件211A中通入脉冲反吹气流，从而通过脉冲反吹气流对该气固分离组件211A中的各个滤袋进行脉冲反吹清灰以使粉尘从这些滤袋上脱离；
对上述气固分离组件211A的脉冲反吹清灰结束后，反吹控制部件又指令下一组气固分离组件211A的反吹装置执行同样的过程，这样依次对一个过滤器211中的所有气固分离组件211A进行脉冲反吹清灰后，再继续对气固分离单元210的另一过滤器211进行脉冲反吹清灰。
当一个气固分离单元210中的两个滤器211均完成脉冲反吹清灰后，再继续对其他气固分离单元210进行在线清灰。
如图1、图3所示，在上述气固分离系统上安装粉尘监测系统。该粉尘监测系统包括信号获取部110、信号传输部120和信号处理部130。其中，信号获取部110的多个粉尘检测部件111部署在图3中的汇流通道220上并分别设置在该汇流通道220上各个用于与各气固分离单元210的净气输出侧连接的连接点之后。
该实施例的粉尘监测系统中，在所述汇流通道220上、位于沿该汇流通道220的气流方向最下游的连接点之后，沿气流方向间隔设置有两个粉尘检测部件111。
该实施例的粉尘监测系统中的粉尘检测部件111与前一实施例中的粉尘检测部件采用相同的粉尘检测部件。
此外，靠近相邻管段之间结合处的粉尘检测部件111优选设置于该相邻管段中管道直径较小的管段上，从而更好确保粉尘检测部件111获得目标信号较高的准确性。
图6为本发明的粉尘监测方法的一个实施例的流程示意图。如图6所示，基于上述粉尘监测系统实施如下粉尘监测方法，该方法包括：
步骤S101:信号获取部110通过分别位于各气固分离单元210净气输出侧的粉尘检测部件111获取目标信号。
步骤S102：信号传输部120输送由信号获取部110获取的目标信号。
步骤S103：信号处理部130接收由信号传输部120输送的目标信号、进行信号处理并输出监测结果。
其中，步骤S103具体包括：
步骤S103A：根据信号传输部120输送的目标信号判断是否有气固分离单元210出现净气粉尘浓度异常状态。
其中，对任意固分离单元210(下称目标单元)输出的净气粉尘浓度是否出现异常状态的判断是通过对与该目标单元对应的粉尘检测部件111所获取的目标信号以及在所述汇流通道220上位于与目标单元对应的粉尘检测部件111下游的至少一个粉尘检测部件111所获取的目标信号进行关联判断后作出的，从而提高判断准确性。
具体而言，若目标单元不是这些固分离单元210中最下游的固分离单元210，则对该目标单元输出的净气粉尘浓度是否出现异常状态的判断是通过对与该目标单元对应的粉尘检测部件111所获取的目标信号以及在所述汇流通道220上位于与目标单元对应的粉尘检测部件111下游的两个粉尘检测部件111所获取的目标信号进行关联判断后作出的。并且，与目标单元对应的粉尘检测部件111和汇流通道220上位于目标单元下游的两个粉尘检测部件111即一共三个粉尘检测部件111之间依次相邻设置。
若目标单元是这些固分离单元210中最下游的固分离单元210，对该目标单元输出的净气粉尘浓度是否出现异常状态的判断是通过对与该目标单元对应的粉尘检测部件111所获取的目标信号以及在所述汇流通道220上位于与目标单元对应的粉尘检测部件111下游的一个粉尘检测部件111所获取的目标信号进行关联判断后作出的。
图7为本发明的粉尘监测方法的一个实施例的关联判断流程示意图。如图7所示，上述关联判断具体包括(以目标单元为非最下游的固分离单元210为例)：
步骤S201：进行对与目标单元对应的粉尘检测部件111所获取的目标信号是否达到设定条件的第一判断。
步骤S202：进行对在所述汇流通道220上位于与目标单元对应的粉尘检测部件111下游的两个粉尘检测部件111所获取的目标信号是否达到设定条件的第二判断。
步骤S203：进行根据第一判断和第二判断的结果对目标单元输出的净气粉尘浓度是否出现异常状态的第三判断。
第三判断时，当第一判断和第二判断的判断结果均为是时作出目标单元输出的净气粉尘浓度出现异常状态的判断结果；当第一判断和第二判断的判断结果均为否时作出目标单元输出的净气粉尘浓度未出现异常状态的判断结果；当第一判断和第二判断的判断结果存在矛盾时执行步骤S204，根据预设分析策略作出分析判断结果。
步骤S204：根据第一判断和第二判断的判断结果总和中是与否所出现的多数者来作出目标单元输出的净气粉尘浓度是否出现异常状态的分析判断结果。
例如，如图8所示，进行第一判断时，与目标单元对应的粉尘检测部件111所获取的目标信号表示为以时间为横坐标、粉尘浓度为纵坐标的曲线(图8中最上面的曲线)，该曲线中出现的一个波峰解释为粉尘浓度的突然增加，若其峰值超过设定的阈值，第一判断的结果则为“是”(否则第一判断的结果为“否”)，具体表示目标单元对应的粉尘检测部件111获取的目标信号达到了设定条件。进行第二判断时，与上述粉尘检测部件111相邻的一个粉尘检测部件111所获取的目标信号表示为以时间为横坐标、粉尘浓度为纵坐标的曲线(图8中中间的曲线)，该曲线中出现的一个波峰解释为粉尘浓度的突然增加，该波峰的出现时间在图8中最上面的曲线的波峰出现时间之后且两者间隔时间为ΔT，若图8中中间的曲线的波峰的峰值超过设定的阈值且间隔时间ΔT也处于合理范围内(即与粉尘通过相关两个粉尘检测部件111的经验时间相差在一定范围内)，则判断结果为“是”；同理，可判断后续粉尘检测部件111获取的目标信号是否达到了设定条件。
若第一判断和第二判断的判断结果总和全部为是或两个为是，则作出目标单元输出的净气粉尘浓度出现异常状态的分析判断结果。否则作为目标单元输出的净气粉尘浓度未出现异常状态的分析判断结果。
上述步骤S204还可以包含将所获取的目标信号与所述分析判断结果相矛盾的粉尘检测部件判断为故障的环节，这时，信号处理部130还可输出指向相应粉尘检测部件故障的通知。
如图6所示，当通过上述步骤S103A判断某气固分离单元210出现净气粉尘浓度异常状态时，还将进行以下操作：
步骤S103B：根据反吹控制部件提供的用于表征气固分离单元210是否存在反吹行为的信息判断出现净气粉尘浓度异常状态的气固分离单元210是否有任意一个气固分离组件211A处于启动反吹后一定时期内且其他气固分离组件211A还未开始反吹。
若将一气固分离单元210中任意一个处于启动反吹后一定时期内且其他气固分离组件211A还未开始反吹的气固分离组件211A称为目标组件，则步骤S103B实际上就是判断出现净气粉尘浓度异常状态的气固分离单元210中是否有目标组件。
步骤S103C：若通过步骤S103B判断出现净气粉尘浓度异常状态的气固分离单元210中有目标组件，则认为该气固分离单元210输出的净气粉尘浓度出现异常状态是由该气固分离单元210中的目标组件的反吹而引发的，信号处理部130输出监测结果，该检测结果表达为可指向出现净气粉尘浓度异常状态的气固分离单元中的目标组件的过滤部件异常的通知。
