Description

一种微电荷感应装置及一种除尘***A micro-charge induction device and a dust removal system 技术领域technical field
本申请的实施例涉及微电荷感应装置(Triboelectric instrument)以及相关的除尘***、除尘***的监测方法、除尘***监测设备、除尘***监测装置、计算机可读存储介质和辅助零部件。Embodiments of the present application relate to a micro-charge induction device (Triboelectric instrument) and a related dust removal system, a monitoring method for a dust removal system, a monitoring device for a dust removal system, a monitoring device for a dust removal system, a computer-readable storage medium, and auxiliary components.
背景技术Background technique
微电荷感应装置(Triboelectric instrument或Triboelectric sensor)是一种通过微电荷感应来探测气流中的颗粒物(固体颗粒物或液体颗粒物)从而获得如颗粒物流量等信息的装置。市面上的代表商品有奥本***(Auburn systems)公司的TRIBO系列产品。Triboelectric instrument or Triboelectric sensor is a device that detects particles (solid particles or liquid particles) in the airflow through micro-charge induction to obtain information such as particle flow. Representative products on the market include TRIBO series products from Auburn systems.
微电荷感应装置主要包括探头(Probe)和信号处理***。其中，探头在使用时***目标空间并在目标空间中的颗粒物经过该探头时产生并输出电流信号，该电流信号作为信号处理***的输入信号；信号处理***则通过对该输入信号的处理获得用于表征颗粒物流量等情况的信息。这里的“目标空间”，可以看作特定的气流流道。无论称作目标空间还是气流流道，总之可以将它们概略的理解为，用于输送气流的壳结构中的气流输送空间或通道。The micro-charge sensing device mainly includes a probe (Probe) and a signal processing system. Among them, the probe is inserted into the target space when in use and generates and outputs a current signal when the particles in the target space pass through the probe, and the current signal is used as the input signal of the signal processing system; Information used to characterize the flow of particulate matter, etc. The "target space" here can be regarded as a specific airflow channel. Regardless of whether they are called target spaces or air flow passages, they can be roughly understood as air flow delivery spaces or passages in the shell structure used to deliver air flow.
现有微电荷感应装置的探头设计为长度较短的探棒。这种形式的探头探测范围比较有限。当有多个不同独立探测区域时，需要数量与独立探测区域数量相应的微电荷感应装置，这时，使用这些微电荷感应装置的成本将非常高昂。此外，当一个独立探测区域的空间大小相比于一个探头而言特别大时，该探头对于这个独立探测区域的探测准确度较低。The probe of the existing micro-charge induction device is designed as a probe with a shorter length. This form of probe detection range is relatively limited. When there are multiple different independent detection areas, the number of micro-charge sensing devices corresponding to the number of independent detection areas is required, and at this time, the cost of using these micro-charge sensing devices will be very high. In addition, when the spatial size of an independent detection area is particularly large compared with that of a probe, the detection accuracy of the probe for this independent detection area is low.
此外，现有微电荷感应装置常常采用探头与信号处理***一体的设计，也有的采用探头与信号处理***分开但探头与信号处理***之间通过专用信号传输线进行较短距离连接的设计。因此，现有微电荷感应装置往往存在受工程现场影响而安装使用受限的难题。In addition, the existing micro-charge induction devices often adopt the integrated design of the probe and the signal processing system, and some adopt the design that the probe and the signal processing system are separated, but the probe and the signal processing system are connected by a short distance through a dedicated signal transmission line. Therefore, the existing micro-charge induction devices often have the problem of limited installation and use due to the influence of the engineering site.

图2为本申请实施例提供的一种微电荷感应装置示意图，该微电荷感应装置可以用于图1所示的控制***。如图2所示，该微电荷感应装置包括探头111和信号处理***112，所述探头111使用时***目标空间(或特定的气流流道)中并在目标空间中的颗粒物经过该探头111时产生并输出电流信号，所述电流信号用作信号处理***112的输入信号。FIG. 2 is a schematic diagram of a micro-charge sensing device provided by an embodiment of the present application, and the micro-charge sensing device can be used in the control system shown in FIG. 1 . As shown in Figure 2, the micro-charge induction device includes a probe 111 and a signal processing system 112, the probe 111 is inserted into the target space (or a specific air flow channel) during use and when the particles in the target space pass through the probe 111 A current signal is generated and output, which is used as an input signal to the signal processing system 112 .
所述探头111可以基于以下的机制而产生电流信号：一，流动过程中的颗粒物接触探头111而在探头111上产生接触电流信号；二，流动过程中的颗粒物从探头111旁边掠过时在探头111上产生感应电流信号。目前能够从市面上获得的微电荷感应装置中，有的微电荷感应装置的信号处理***112无法对所述感应电流信号进行有效处理，因此这类微电荷感应装置实际上是利用上述机制一所产生的电流信号,但是，这类微电荷感应装置往往不够灵敏，测量精度低。也有微电荷感应装置的信号处理***112能够对所述感应电流信号进行有效处理，例如奥本***(Auburn systems)公司的TRIBO系列的微电荷感应装置，这时，这种微电荷感应装置既可以同时利用上述机制一和机制二所产生的电流信号，也可以选择只利用上述机制二所产生的电流信号。类似于TRIBO系列的微电荷感应装置这类微电荷感应装置测量精度更高。为了仅仅利用机制二所产生的电流信号，可以在探头111表面覆盖一层绝缘材料，此时，流动过程中的颗粒物即使接触探头111也不会在相互接触的颗粒物与探头之间产生电荷迁移，因而不会在探头111上产生接触电流信号。仅仅利用机制二所产生的电流信号的好处之一在于：将探头111表面覆盖一层绝缘材料起到保护探头的作用，并且避免使用过程中探头111与构成所述气流流道的壳部件之间被附着在探头111上的物质(例如导电的颗粒物或气流中析出的导电液体)或因其他原因导通引起短路。The probe 111 can generate a current signal based on the following mechanisms: one, the particles in the flow process contact the probe 111 to generate a contact current signal on the probe 111; two, the particles in the flow process pass by the probe 111 generate an induced current signal. Among the currently available micro-charge sensing devices on the market, the signal processing system 112 of some micro-charge sensing devices cannot effectively process the induced current signal, so this type of micro-charge sensing device actually utilizes the above-mentioned mechanism. However, such micro-charge sensing devices are often not sensitive enough and have low measurement accuracy. There is also a signal processing system 112 of a micro-charge sensing device that can effectively process the induced current signal, such as the micro-charge sensing device of the TRIBO series of Auburn systems (Auburn systems), at this time, this micro-charge sensing device can either The current signals generated by the above-mentioned mechanism 1 and mechanism 2 are used at the same time, or only the current signal generated by the above-mentioned mechanism 2 can be selected. Micro-charge sensing devices like the TRIBO series have higher measurement accuracy. In order to only use the current signal generated by the second mechanism, a layer of insulating material can be covered on the surface of the probe 111. At this time, even if the particles in the flow process touch the probe 111, there will be no charge migration between the particles in contact with the probe. Therefore, no touch current signal will be generated on the probe 111 . One of the advantages of using only the current signal generated by the second mechanism is that: the surface of the probe 111 is covered with a layer of insulating material to protect the probe, and to avoid the gap between the probe 111 and the shell components forming the airflow channel during use. Substances attached to the probe 111 (such as conductive particles or conductive liquid precipitated in the gas flow) or conduction due to other reasons cause a short circuit.
为了提高探头111对目标空间中的颗粒物探测的准确性，通常需要在目标空间与该目标空间的外部环境之间进行电磁屏蔽，防止目标空间的外部环境中的颗粒物流动对探测产生干扰。通常，目标空间的壳结构可由钢板等金属材料制作，这样，所述目标空间与该目标空间的外部环境之间就要可以通过该壳结构实现电磁屏蔽。当然，也可以在目标空间与该目标空间的外部环境之间设置其他屏蔽结构或材料来实现电磁屏蔽。In order to improve the accuracy of the probe 111 in detecting particles in the target space, electromagnetic shielding is generally required between the target space and the external environment of the target space to prevent the flow of particles in the external environment of the target space from interfering with the detection. Usually, the shell structure of the target space can be made of metal materials such as steel plates, so that electromagnetic shielding can be realized between the target space and the external environment of the target space through the shell structure. Certainly, other shielding structures or materials may also be arranged between the target space and the external environment of the target space to realize electromagnetic shielding.
由于探头111产生并输出的电流信号是十分微弱的，要使这个电流信号能够被后续设备(例如所述PLC控制器120)所处理，同时确保这个电流信号受到尽可低的干扰和/或其他导致信号失真的不利影响，需要将探头111产生并输出的电流信号通过信号处理***112进行处理，以输出能够被后续设备(例如所述PLC控制器120)所处理的准确信号。专利号为US5448172的专利文件中提供了一种信号处理***，该信号处理***包括变送器(converter means)，其基本作用就是对探头111产生并输出的电流信号进行放大。通常，信号处理***112用于输出标准工业信号，如4-20毫安电流或1-5伏电压的信号。信号处理***112的输出信号通常可以是用来表征微电荷感应装置探测到的颗粒物流量的。Since the current signal generated and output by the probe 111 is very weak, the current signal should be processed by subsequent equipment (such as the PLC controller 120), while ensuring that the current signal is subject to as little interference and/or other As a result of adverse effects of signal distortion, the current signal generated and output by the probe 111 needs to be processed by the signal processing system 112 to output an accurate signal that can be processed by subsequent equipment (such as the PLC controller 120 ). Patent No. US5448172 provides a signal processing system, the signal processing system includes a converter (converter means), the basic function of which is to amplify the current signal generated and output by the probe 111. Typically, the signal processing system 112 is used to output standard industrial signals, such as 4-20 mA current or 1-5 volt signals. The output signal of the signal processing system 112 can generally be used to characterize the particle flow detected by the micro-charge sensing device.
图3为本申请实施例提供的一种除尘***的结构示意图，该除尘***可以使用图1所示的控制***。如图3所示，所述除尘***包括除尘单元组200，所述除尘单元组200包含至少两个除尘单元210，所述至少两个除尘单元210中各除尘单元210均设有独立净气箱211，各所述独立净气箱211组成目标空间。FIG. 3 is a schematic structural diagram of a dust removal system provided by an embodiment of the present application. The dust removal system may use the control system shown in FIG. 1 . As shown in Figure 3, the dust removal system includes a dust removal unit group 200, the dust removal unit group 200 includes at least two dust removal units 210, and each dust removal unit 210 in the at least two dust removal units 210 is provided with an independent clean air box 211. Each of the independent clean air boxes 211 forms a target space.
所述至少两个除尘单元210中的各除尘单元210通常为通过过滤元件212对气流中的颗粒物进行物理拦截的除尘单元，此时，这些除尘单元210还可以分别设置用于对自身过滤元件212进行反吹再生的反吹***，并且，所述至少两个除尘单元210中任一除尘单元210的反吹***通常可与所述至少两个除尘单元210中的其余除尘单元210的反吹***错时运行，这样，当一个除尘单元210的反吹***正在运行时其他除尘单元210还可以正常的进行工作(除尘)。Each dust removal unit 210 in the at least two dust removal units 210 is usually a dust removal unit that physically intercepts particulate matter in the airflow through a filter element 212. A blowback system for blowback regeneration, and the blowback system of any one dust removal unit 210 in the at least two dust removal units 210 can usually be combined with the blowback systems of the remaining dust removal units 210 in the at least two dust removal units 210 Staggered operation, like this, when the blowback system of a dust removal unit 210 is running, other dust removal units 210 can also work normally (dust removal).
所述过滤元件212可以是布袋、滤筒等各类由具有透过性的材料(如膨体聚四氟乙烯、多孔陶瓷)制成的部件。 所述反吹再生是除尘单元恢复过滤元件212透过性的惯用手段，广泛应用于布袋除尘器、滤筒式除尘器等通过过滤元件对气流中的颗粒物进行物理拦截的过滤器中。The filter element 212 can be a cloth bag, a filter cartridge and other various components made of permeable materials (such as expanded polytetrafluoroethylene, porous ceramics). The back-blowing regeneration is a common method for the dust removal unit to restore the permeability of the filter element 212, and it is widely used in filters such as bag filter and cartridge filter that physically intercept the particulate matter in the airflow through the filter element.
当任何一个过滤元件212存在破损时，对该过滤元件的反吹再生往往会导致该过滤元件212上的破损部位暴露，进而引发所在除尘单元210的净气箱211中的颗粒物浓度的突然升高。此外，过滤元件212的破损也容易导致对应除尘单元210的净气箱211中颗粒物沉积，反吹再生时也会引起对应净气箱211中颗粒物浓度升高。而由于所述至少两个除尘单元210中任一除尘单元210的反吹***与所述至少两个除尘单元210中的其余除尘单元210的反吹***是错时运行的，如果在某一除尘单元210的反吹***运行的对应时间中探测到对应独立净气箱211中颗粒物浓度的突然升高，则可以定位出可能发生过滤元件破损的除尘单元210。When any filter element 212 is damaged, the blowback regeneration of the filter element will often cause the damaged part on the filter element 212 to be exposed, thereby causing a sudden increase in the concentration of particulate matter in the clean air box 211 of the dust removal unit 210 . In addition, the breakage of the filter element 212 may also easily lead to the deposition of particulate matter in the clean air box 211 corresponding to the dust removal unit 210 , and the concentration of particulate matter in the corresponding clean air box 211 will also increase during back-blowing regeneration. And because the blowback system of any dust removal unit 210 in the at least two dust removal units 210 and the blowback systems of the remaining dust removal units 210 in the at least two dust removal units 210 are staggered operation, if in a certain dust removal unit If a sudden increase in the particle concentration in the corresponding independent clean air box 211 is detected during the operation of the back blowing system at 210, the dust removal unit 210 that may be damaged by the filter element can be located.
在上述除尘***的一个可选实施方式中，所述除尘单元组200的所述至少两个除尘单元210中各除尘单元210分别为一个布袋除尘器。各布袋除尘器中，过滤元件212采用布袋，多个布袋悬挂在布袋除尘器内的孔板214下方，孔板214上方为独立净气箱211，孔板214下方为原气箱。各布袋除尘器的原气箱分别通过对应的进气阀221与进气管220连接，各布袋除尘器的独立净气箱211分别通过对应的排气阀231与排气管230连接。当进气管220汇聚至同一管道时，该同一管道可称为进气总管；当排气管230汇聚至同一管道时，该同一管道可称为排气总管。各布袋除尘器的反吹***包括喷吹管213、脉冲阀、气包和控制部件，每根喷吹管213上间隔排列的各喷口分别对应一排布袋中的各布袋的上端开口，且每根喷吹管213通过一个脉冲阀连接到对应的气包，控制部件主要用于控制脉冲阀的开启和关闭。In an optional embodiment of the above dust removal system, each dust removal unit 210 of the at least two dust removal units 210 in the dust removal unit group 200 is a bag filter respectively. In each bag filter, the filter element 212 adopts a cloth bag, and a plurality of cloth bags are hung below the orifice plate 214 in the bag filter. Above the orifice plate 214 is an independent clean air box 211, and below the orifice plate 214 is a raw air box. The raw air box of each bag filter is connected to the intake pipe 220 through the corresponding inlet valve 221, and the independent clean air box 211 of each bag filter is connected to the exhaust pipe 230 through the corresponding exhaust valve 231 respectively. When the intake pipes 220 converge into the same pipe, the same pipe may be called an intake manifold; when the exhaust pipes 230 converge into the same pipe, the same pipe may be called an exhaust manifold. The blowback system of each bag filter includes blowing pipe 213, pulse valve, air bag and control components. The nozzles arranged at intervals on each blowing pipe 213 correspond to the upper openings of each bag in a row of cloth bags, and each nozzle The blowpipe 213 is connected to the corresponding air bag through a pulse valve, and the control part is mainly used to control the opening and closing of the pulse valve.
上述除尘单元组200运行时，待除尘气体(原气)从进气管220、进气阀221进入原气箱，然后在原气箱中受到布袋的过滤，过滤后的已除尘气体(净气)进入对应的独立净气箱211，然后经排气阀231、排气管230输出。上述各布袋除尘器的反吹再生的过程为：当任意一个布袋除尘器需要进行反吹再生时，首先关闭该需要进行反吹再生的布袋除尘器对应的排气阀231，然后控制部件控制该需要进行反吹再生的布袋除尘器的各脉冲阀按先后顺序依次开启，当一个脉冲阀开启时，对应气包中的压缩气体迅速从相应喷吹管213的各个喷口喷出并进入对应一排布袋中实现这一排布袋的反吹再生，直至每一排布袋均完成反吹再生，这时，一个布袋除尘器的反吹再生完成。当一个布袋除尘器的反吹再生完成后，再打开该布袋除尘器的排气阀231，这时，这个布袋除尘器又可以重新开始工作(过滤)。通过重复上述方式进行另一个布袋除尘器的反吹再生，直到全部布袋除尘器完成反吹再生。由此可见，上述除尘***中任意一个布袋除尘器的反吹***与其余布袋除尘器的反吹***是错时运行的。When the above-mentioned dedusting unit group 200 is in operation, the gas to be dedusted (raw gas) enters the raw gas box from the intake pipe 220 and the intake valve 221, and then is filtered by a cloth bag in the raw gas box, and the filtered dedusted gas (clean gas) enters The corresponding independent clean air box 211 is then output through an exhaust valve 231 and an exhaust pipe 230 . The process of back blowing and regeneration of the above-mentioned bag filters is as follows: when any bag filter needs to perform back blow regeneration, first close the exhaust valve 231 corresponding to the bag filter that needs to perform back blow regeneration, and then the control unit controls the The pulse valves of the bag filter that need back blowing and regeneration are opened in sequence. When a pulse valve is opened, the compressed gas in the corresponding air bag is quickly ejected from each nozzle of the corresponding blowing pipe 213 and enters the corresponding row of bags Realize the back-flush regeneration of this row of bags until each row of bags has completed the back-flush regeneration. At this time, the back-flush regeneration of a bag filter is completed. After the back blowing regeneration of a bag filter is completed, the exhaust valve 231 of the bag filter is opened, and at this moment, the bag filter can start working (filtering) again. By repeating the above method, carry out the back blowing regeneration of another bag filter until all the bag dust collectors complete the back blowing regeneration. It can be seen that the back blowing system of any bag filter in the above dust removal system and the back blowing system of the other bag filters are operated at staggered times.
正如上面描述的，当任意一个布袋除尘器需要进行反吹再生时，首先关闭该需要进行反吹再生的布袋除尘器对应的排气阀231，然后才会启动反吹，这种反吹方式通常称为“离线反吹”。离线反吹仅仅是目前已知的一种反吹方式，而目前已知的另一种反吹方式为“在线反吹”。在线反吹时，进行反吹再生的布袋除尘器所对应的排气阀231处于开启状态。上述除尘***并不限于采用“离线反吹”。As described above, when any bag filter needs to be regenerated by back blowing, first close the exhaust valve 231 corresponding to the bag filter that needs to be regenerated by back blowing, and then start back blowing. Called "offline blowback". Off-line backflush is only one known backflush method, and another known backflush method is "online backflush". During online back blowing, the exhaust valve 231 corresponding to the bag filter performing back blowing regeneration is in an open state. The above-mentioned dedusting system is not limited to the use of "off-line backflushing".
上面的描述中已经指出，当任何一个布袋存在破损时，对该布袋的反吹再生往往会导致该布袋上的破损部位暴露，进而引发所在布袋除尘器的净气箱211中的颗粒物浓度的突然升高。此外，该布袋的破损也容易导致所在布袋除尘器的净气箱211中颗粒物沉积，反吹再生时也会引起颗粒物浓度升高。因此，该除尘***可以使用上述控制***以便及时发现除尘***中可能存在布袋破损的布袋除尘器，甚至是找出可能存在布袋破损的布袋除尘器中具体哪一些布袋可能发生破损。由此，需要将上述控制***应用在该除尘***中。It has been pointed out in the above description that when any bag is damaged, the back blowing regeneration of the bag will often lead to the exposure of the damaged part of the bag, which will cause a sudden increase in the concentration of particulate matter in the clean air box 211 of the bag filter. raised. In addition, the breakage of the bag also easily leads to the deposition of particulate matter in the clean air box 211 of the bag filter where it is located, and the concentration of particulate matter will also increase during backflush regeneration. Therefore, the above-mentioned control system can be used in the dust removal system to detect in time the bag filters that may have damaged bags in the dust removal system, and even find out which bags in the bag filters that may have damaged bags may be damaged. Therefore, it is necessary to apply the above-mentioned control system to the dust removal system.
作为将上述控制***应用在该除尘***中的一种具体实施方式，上述控制***的PLC控制器120可以对除尘***中所述至少两个除尘单元210的反吹***进行控制，这时，各脉冲阀将作为所述仪器仪表130中的设备而与PLC控制器120的对应输出端口连接，从而通过PLC控制器120来控制这些脉冲阀的开闭。此外，各排气阀231以及其他可能的设备也可以分别作为所述仪器仪表130中的设备而与PLC控制器120的对应输出端口连接。而所述控制***的微电荷感应装置110可以部署在所述至少两个除尘单元210中各独立净气箱211中或所述排气总管中。当所述控制***的微电荷感应装置110部署在所述至少两个除尘单元210中各独立净气箱211中时，通过微电荷感应装置 110探测各独立净气箱211中的颗粒物浓度变化；当所述控制***的微电荷感应装置110部署在排气总管中时，通过微电荷感应装置110探测排气总管中的颗粒物浓度变化。这样，通过PLC控制器120既能够获得所述至少两个除尘单元210的反吹信息，又能够获得微电荷感应装置110的信号处理***112的输出信息，进而通过过所述反吹信息能够确定所述至少两个除尘单元中各除尘单元的反吹***的运行时机，通过所述输出信息能够确定探测到的颗粒物瞬时流量随时间的变化(这里，颗粒物浓度与颗粒物流量是相关的概念，均能够反映颗粒物的多少)，最后根据所述反吹信息与输出信息确定当探测到的颗粒物瞬时流量异常升高时对应运行反吹***的除尘单元，从而能够找到可能存在过滤元件破损的除尘单元。As a specific implementation of applying the above-mentioned control system to the dust removal system, the PLC controller 120 of the above-mentioned control system can control the blowback systems of the at least two dust removal units 210 in the dust removal system. At this time, each The pulse valves will be connected to corresponding output ports of the PLC controller 120 as devices in the instrumentation 130 , so that the opening and closing of these pulse valves are controlled by the PLC controller 120 . In addition, each exhaust valve 231 and other possible devices may also be connected to corresponding output ports of the PLC controller 120 as devices in the instrumentation 130 . The micro-charge induction device 110 of the control system can be deployed in each independent clean air box 211 of the at least two dust removal units 210 or in the exhaust main pipe. When the micro-charge sensing device 110 of the control system is deployed in each independent clean air box 211 in the at least two dust removal units 210, the micro-charge sensing device 110 detects the change in the concentration of particulate matter in each independent clean air box 211; When the micro-charge sensing device 110 of the control system is deployed in the exhaust manifold, the micro-charge sensing device 110 detects changes in the concentration of particulate matter in the exhaust manifold. In this way, the back-blowing information of the at least two dust removal units 210 can be obtained through the PLC controller 120, and the output information of the signal processing system 112 of the micro-charge sensing device 110 can be obtained, and then through the back-blowing information can be determined The operation timing of the blowback system of each dust removal unit in the at least two dust removal units, the output information can be used to determine the change of the detected particle instantaneous flow rate with time (here, particle concentration and particle flow are related concepts, both It can reflect the amount of particulate matter), and finally, according to the backflush information and output information, determine the dust removal unit corresponding to the operation of the backflush system when the instantaneous flow rate of the detected particulate matter is abnormally increased, so that the dust removal unit that may have a damaged filter element can be found.
例如，在采用上述离线反吹方案的情况下，当所述控制***的微电荷感应装置110部署在所述至少两个除尘单元210中各独立净气箱211中时，当获得所述至少两个除尘单元210中其中一个除尘单元210所对应的排气阀231在该除尘单元210反吹结束后开启的信息时，如果部署于该除尘单元210的独立净气箱211的微电荷感应装置110监测到颗粒物瞬时流量异常升高，则可以认为该除尘单元210中可能存在过滤元件破损。又如，在采用上述离线反吹方案的情况下，当所述控制***的微电荷感应装置110部署在所述排气总管中时，当获得所述至少两个除尘单元210中其中一个除尘单元210所对应的排气阀231在该除尘单元210反吹结束后开启的信息时，如果部署于所述排气总管的微电荷感应装置110随即监测到颗粒物瞬时流量异常升高，则可以认为该除尘单元210中可能存在过滤元件破损。For example, in the case of adopting the above-mentioned off-line backflushing scheme, when the micro-charge induction device 110 of the control system is deployed in each independent clean air box 211 of the at least two dust removal units 210, when the at least two When the exhaust valve 231 corresponding to one of the dust removal units 210 in the dust removal unit 210 is opened after the dust removal unit 210 is blown back, if the micro-charge induction device 110 deployed in the independent clean air box 211 of the dust removal unit 210 If an abnormal increase in the instantaneous flow rate of particulate matter is detected, it can be considered that there may be damage to the filter element in the dust removal unit 210 . As another example, in the case of adopting the above-mentioned offline backflushing scheme, when the micro-charge sensing device 110 of the control system is deployed in the exhaust main pipe, when one of the at least two dust removal units 210 is obtained When the exhaust valve 231 corresponding to 210 is opened after the dust removal unit 210 is blown back, if the micro-charge sensing device 110 deployed in the exhaust main pipe immediately detects an abnormal increase in the instantaneous flow rate of particulate matter, it can be considered that the There may be a broken filter element in the dust removal unit 210 .
然而，现有微电荷感应装置的探头设计为长度较短的探棒，这种形式的探头探测范围比较有限，如果将使用这种形式的探头的微电荷感应装置110部署在各独立净气箱211中，则每一个独立净气箱211均需要至少一个微电荷感应装置110，这时，使用这些微电荷感应装置的成本将非常高昂；而如果将使用这种形式的探头的微电荷感应装置110部署排气总管中，由于探头的探测范围本来就比较有限，加上排气总管的通道的横截面面积又比较大，因此该探头对于排气总管而言的探测准确度较低。However, the probes of the existing micro-charge induction devices are designed as probes with a shorter length, and the detection range of this type of probe is relatively limited. 211, then each independent clean gas box 211 all needs at least one micro-charge sensing device 110, at this moment, the cost of using these micro-charge sensing devices will be very high; and if the micro-charge sensing device of this form of probe will be used In 110 deployment of the exhaust main pipe, since the detection range of the probe is relatively limited, and the cross-sectional area of the passage of the exhaust main pipe is relatively large, the detection accuracy of the probe for the exhaust main pipe is relatively low.
此外，现有微电荷感应装置常常采用探头与信号处理***一体的设计，也有的采用探头与信号处理***分开但探头与信号处理***之间通过专用信号传输线进行较短距离连接的设计。因此，现有微电荷感应装置往往存在受工程现场影响而安装使用受限的难题。In addition, the existing micro-charge induction devices often adopt the integrated design of the probe and the signal processing system, and some adopt the design that the probe and the signal processing system are separated, but the probe and the signal processing system are connected by a short distance through a dedicated signal transmission line. Therefore, the existing micro-charge induction devices often have the problem of limited installation and use due to the influence of the engineering site.

下面将以使用电缆1111制作探头111的第一微电荷感应装置110A说明第一微电荷感应装置110A的安装过程以及安装后的第一微电荷感应装置110A。The installation process of the first micro-charge sensing device 110A and the installed first micro-charge sensing device 110A will be described below with the first micro-charge sensing device 110A using the cable 1111 to make the probe 111 .
一个探头大致上的安装过程为：先在预先设计需要探头111两端分别所在的独立净气箱的内壁上安装牵拉装置113，所述牵拉装置113用于对电缆1111进行牵拉以使电缆1111能够安装在所述壳结构中。然后将一根电缆1111的第一端所在的第一段通过第一转折加工形成第一转折段1112，所述第一转折段1112与所述电缆1111的本体之间形成第一线环1113，所述第一线环1113用于连接对应的牵拉装置113(可以将第一转折段1112穿过对应牵拉装置113上的孔从而使第一线环1113与对应牵拉装置113连接)。所述第一转折段1112再通过第二转折加工形成第二转折段1114，所述第二转折段1114与所述本体之间的夹角＞0°且＜180°，这时，第二转折段1114相当于从电缆1111的本体上分岔出来，因此，第二转折段1114刚好可以用作所述信号传输线1124的至少一段，用以实现电流信号的输出。关于第二转折段1114与信号处理***112之间的连接，可以参考前述“第一微电荷感应装置的信号处理***”部分中的内容，在此不再赘述。此后，将电缆1111的第二端所在的第二段通过第三转折加工形成第三转折段，所述第三转折段与所述电缆1111的本体之间固结并形成第二线环，所述第二线环用于连接对应的牵拉装置(可以将第三转折段穿过对应牵拉装置上的孔从而使第二线环与对应牵拉装置连接)。这样，就能够通过电缆1111第一端处用于连接第一线环1113的牵拉装置113和电缆1111第二端处用于连接第二线环的牵拉装置使电缆1111安装在所述壳结构中。可见，上述安装过程施工并不复杂，能够做到简便快捷。The general installation process of a probe is as follows: first install the pulling device 113 on the inner wall of the independent clean air box where the two ends of the probe 111 are pre-designed, and the pulling device 113 is used to pull the cable 1111 so that Cables 1111 can be installed in the shell structure. Then, the first section where the first end of a cable 1111 is located is processed through the first turning process to form a first turning section 1112, and a first loop 1113 is formed between the first turning section 1112 and the body of the cable 1111, The first wire loop 1113 is used to connect the corresponding pulling device 113 (the first turning section 1112 can be passed through the hole on the corresponding pulling device 113 so as to connect the first wire loop 1113 to the corresponding pulling device 113 ). The first turning section 1112 forms a second turning section 1114 through a second turning process, and the angle between the second turning section 1114 and the body is >0° and <180°. At this time, the second turning section The section 1114 is equivalent to branching out from the main body of the cable 1111, therefore, the second turning section 1114 can just be used as at least one section of the signal transmission line 1124 to realize the output of the current signal. As for the connection between the second turning section 1114 and the signal processing system 112 , reference may be made to the content in the aforementioned "Signal Processing System of the First Micro-charge Sensing Device", and details are not repeated here. Thereafter, the second section where the second end of the cable 1111 is located is processed through a third turning process to form a third turning section, and the third turning section is solidified with the body of the cable 1111 to form a second wire loop. The second wire loop is used to connect the corresponding pulling device (the third turning section can be passed through the hole on the corresponding pulling device so that the second wire loop is connected with the corresponding pulling device). In this way, the cable 1111 can be installed in the shell structure through the pulling device 113 at the first end of the cable 1111 for connecting the first loop 1113 and the pulling device at the second end of the cable 1111 for connecting the second loop middle.

第二微电荷感应装置的安装Installation of the second micro-charge induction device
下面将以使用电缆1111制作探头111的第二微电荷感应装置110B说明第二微电荷感应装置110B的安装过程以及安装后的第二微电荷感应装置110B。The installation process of the second micro-charge sensing device 110B and the installed second micro-charge sensing device 110B will be described below by using the cable 1111 to make the probe 111 to the second micro-charge sensing device 110B.
一个探头大致上的安装过程为：先在排气管230的内壁上布置安装牵拉结构115。然后将一根电缆1111的第一端所在的第一段通过第一转折加工形成第一转折段，所述第一转折段与所述电缆1111的本体之间形成第一线环，所述第一线环用于连接对应的牵拉结构115A(可以将第一转折段穿过对应牵拉装置115上的孔从而使第一线环与对应牵拉装置115A连接)。所述第一转折段再通过第二转折加工形成第二转折段，所述第二转折段与所述本体之间的 夹角＞0°且＜180°，这时，第二转折段相当于从电缆1111的本体上分岔出来，因此，第二转折段刚好可以用作所述信号传输线1124的至少一段，用以实现电流信号的输出。关于第二转折段与信号处理***112之间的连接，可以参考前述“第一微电荷感应装置的信号处理***”部分中的内容，在此不再赘述。此后，将电缆1111的第二端依次穿过牵拉装置115B的电缆穿孔、牵拉装置115C的电缆穿孔和牵拉装置115D的电缆穿孔，每穿过一个电缆穿孔时即需要对电缆1111进行转折加工；其中，将电缆1111的第二端所在的第二段通过第三转折加工形成第三转折段，所述第三转折段与所述电缆1111的本体之间固结并形成第二线环，所述第二线环具体用于连接牵拉装置115D(可以将第三转折段穿过牵拉装置115D上的孔从而使第二线环与牵拉装置115D连接)。这样，就使得所述电缆1111通过这些牵拉结构115牵引而在所述横截面上曲折布设。可见，上述安装过程施工并不复杂，能够做到简便快捷。The general installation process of a probe is as follows: first arrange and install the pulling structure 115 on the inner wall of the exhaust pipe 230 . Then, the first section where the first end of a cable 1111 is located is processed through the first turning process to form a first turning section, and a first wire loop is formed between the first turning section and the body of the cable 1111, and the first turning section The wire loop is used to connect the corresponding pulling structure 115A (the first turning section can be passed through the hole on the corresponding pulling device 115 so as to connect the first wire loop to the corresponding pulling device 115A). The first turning section is then processed through a second turning section to form a second turning section, and the angle between the second turning section and the body is >0° and <180°. At this time, the second turning section is equivalent to Branched out from the main body of the cable 1111 , therefore, the second turning section can just be used as at least one section of the signal transmission line 1124 to realize the output of the current signal. As for the connection between the second turning section and the signal processing system 112 , reference may be made to the aforementioned content in the “Signal Processing System of the First Micro-charge Sensing Device”, and details will not be repeated here. Thereafter, the second end of the cable 1111 is sequentially passed through the cable hole of the pulling device 115B, the cable hole of the pulling device 115C and the cable hole of the pulling device 115D, and the cable 1111 needs to be turned every time it passes through a cable hole. Processing; wherein, the second section where the second end of the cable 1111 is located is processed through a third turning process to form a third turning section, and the third turning section is consolidated with the body of the cable 1111 to form a second wire loop, The second wire loop is specifically used to connect the pulling device 115D (the third turning section can be passed through the hole on the pulling device 115D so as to connect the second wire loop to the pulling device 115D). In this way, the cables 1111 are pulled by the pulling structures 115 to be arranged in a meandering manner on the cross section. It can be seen that the construction of the above installation process is not complicated, and can be done simply and quickly.
