技术领域
本申请涉及布袋除尘器脉冲阀控制技术领域，具体涉及一种布袋除尘器脉冲阀的控制电路。
背景技术
脉冲布袋除尘器是在布袋除尘器的基础上，改进的新型高效脉冲袋式除尘器，为了进一步完善脉冲袋式除尘器，改后的脉冲袋式除尘器保留了净化效率高、处理气体能力大、性能稳定、操作方便、滤袋寿命长和维修工作量小等优点。现有的布袋除尘器脉冲阀控制存在以下问题：(1)布袋除尘器脉冲阀单点控制，即采用点对点控制方案，通过PLC/DCS模块的一个开关量输出点开关触发一个脉冲阀，但由于脉冲阀数量较多，所需PLC/DCS模块数量就多，在控制系统搭建，控制柜制作，柜体安装，施工调试等方面增加很多的制作和施工工作量，尤其浪费电缆材料，施工材料，人工等，不利于工程的造价与施工进展，同时浪费很多资源，对日后设备维护也增加不少的工作量。(2)布袋除尘器脉冲阀矩阵控制，采用中间继电器组组成的矩阵电路，进行分组工作，虽然一定程度上减少了控制中的PLC/DCS输出点，但在传统的矩阵电路中容易造成脉冲阀的误动作，因此在每一脉冲阀的回路中串联了一个二极管，根据二极管的单向导通性，有效解决了脉冲阀的误动作，但该种电路无法监控当前脉冲阀的工作状态，且无法释放脉冲阀动作后残余感应电流，导致二极管工作寿命严重缩短，且无法毫秒级精确控制脉冲阀开关时间，严重影响除尘器的清灰效果。(3) 脉冲控制仪或现场总线控制，需要就地设置控制箱，且对运行环境及通讯要求极高，但除尘器顶部运行环境存在高灰尘、大振动的特点，假设就地控制箱通讯出现故障，该控制箱内所有脉冲阀都无法正常工作，虽然能解决部分材料及设备问题，但仍然未解决可靠性和精确性的问题。

实施例
本申请实施例提供一种布袋除尘器脉冲阀的控制电路，如图1所示，布袋除尘器脉冲阀包括多个仓室脉冲阀组，每个仓室脉冲阀组包括多个脉冲阀。
如图2所示，本申请实施例的布袋除尘器脉冲阀的控制电路包括：控制模块1、行选矩阵控制电路2、列选矩阵控制电路3。
如图2所示，控制模块1包括两个输入端、多个第一输出端及多个第二输出端，控制模块1的第一输入端与外接电源的正极供电端连接，控制模块1的第二输入端与外接电源的负极供电端连接；行选矩阵控制电路2具有多个输入端及多个输出端，行选矩阵控制电路2的每个输入端均与控制模块1的一个第一输出端连接；列选矩阵控制电路3包括一个公共输入端、一个公共输出端、多个非公共输入端及多个非公共输出端，列选矩阵控制电路3的公共输入端与行选矩阵控制电路2的一个输出端连接，列选矩阵控制电路3的公共输出端与一个仓室脉冲阀组的每个脉冲阀的第一端连接，列选矩阵控制电路3的每个非公共输入端均与控制模块1的一个第二输出端连接，列选矩阵控制电路3的每个非公共输出端与同一个仓室脉 冲阀组的一个脉冲阀的第二端连接。
具体地，本申请实施例的行选矩阵控制电路2的输入端与输出端成对出现，且行选矩阵控制电路2的输入端数量及其输出端数量与布袋除尘器所包含的仓室脉冲阀组数量相同，每个列选矩阵控制电路3对应一个仓室脉冲阀组，即列选矩阵控制电路3的数量与仓室脉冲阀组数量相同，每个列选矩阵控制电路3的非公共输入端与非公共输出端成对出现，且每个列选矩阵控制电路3的非公共输入端数量与非公共输出端数量，与其所对应的仓室脉冲阀组所包含的脉冲阀数量相同。
示例性地，若布袋除尘器内包括2个仓储脉冲阀组(仓储脉冲阀组#A及仓储脉冲阀组#B)，仓储脉冲阀组#A及仓储脉冲阀组#B均包含3个脉冲阀，则本申请实施例的控制模块1包括两个第一输出端，两组第二输出端，每组第二输出端均包含3个第二输出端，行选矩阵控制电路2包括2个输入端、2个输出端，本申请实施例包括两个列选矩阵控制电路3(列选矩阵控制电路#31及列选矩阵控制电路#32)，列选矩阵控制电路#31的公共输入端与行选矩阵控制电路2的一个输出端连接，列选矩阵控制电路#31的公共输出端与仓储脉冲阀组#A的每个脉冲阀的第一端连接，列选矩阵控制电路#31的每个非公共输入端与控制模块1的一组第二输出端内的对应第二输出端连接，列选矩阵控制电路#31的每个非公共输出端与仓储脉冲阀组#A的相应脉冲阀的第二端连接，同理，列选矩阵控制电路#32的公共输入端与行选矩阵控制电路2的一个输出端连接，列选矩阵控制电路#32的公共输出端与仓储脉冲阀组#B的每个脉冲阀的第一端连接，列选矩阵控制电路#32的每个非公共输入端与控制模块1的一组第二输出端内的对应第二输出端连接，列选矩阵控制电路#32的每个非公共输出端与仓储脉冲阀组#B的相应脉冲阀的第二端连接。
进一步地，控制模块1通过控制行选矩阵控制电路2的相应输入端与外接电源的负极供电端连通，以选择对应的仓室脉冲阀组；控制模块1通过控制相应的列选矩阵控制电路3的相应的非公共输入端与外接电源的正极供电端连通，以选择对应的脉冲阀。
具体地，本申请实施例的控制模块1通过选通行选矩阵控制电路2内部电路使得脉冲阀的第一端先与外接电源接通，然后再通过选通列选矩阵 控制电路内部电路使得脉冲阀的第二端再与外接电源接通。即本申请实施例的控制模块1通过矩阵的方式对全部脉冲阀进行控制，将每个仓室脉冲阀作为矩阵的一行，每个仓室脉冲阀所包含的脉冲阀作为该行的每列的元素，本申请实施例的控制模块1通过选通行矩阵控制电路内部电路，对待控脉冲阀进行行定位，通过选通列矩阵控制电路内部电路，对待控脉冲阀进行列定位。
示例性地，若布袋除尘器内包括2个仓储脉冲阀组(仓储脉冲阀组#A及仓储脉冲阀组#B)，仓储脉冲阀组#A包含3个脉冲阀(脉冲阀#A1、脉冲阀#A2、脉冲阀#A3)及仓储脉冲阀组#B包含3个脉冲阀(脉冲阀#B1、脉冲阀#B2、脉冲阀#B3)，列选矩阵控制电路#31与仓储脉冲阀组#A对应，列选矩阵控制电路#32与仓储脉冲阀组#B对应，当需要脉冲阀#A1动作时，首先控制模块1控制行选矩阵控制电路2中与列选矩阵控制电路#31的公共输入端连接的输出端，与外接电源的负极供电端接通，由于列选矩阵控制电路#31的公共输入端与公共输出端可以由一条公共线直连，因此，脉冲阀#A1～脉冲阀#A3的第一端均依次通过列选矩阵控制电路#31的输出端、列选矩阵控制电路#31的输入端、行选矩阵控制电路2与外接电源的负极供电端连通，至此实现对仓储脉冲阀组定位，即实现对脉冲阀#A1的行定位。然后控制模块1控制列选矩阵控制电路#31中与脉冲阀#A1的第二端连接的非公共输出端所对应的非公共输入端，与外接电源的正极供电端接通，由于列选矩阵控制电路#31的非公共输出端及非公共输入端之间的电路内部仅具有单向导电性、不具备开关性，因此只要非公共输入端与外接电源的正极供电端接通，则所对应的非公共输出端与外接电源的正极供电端接通，故，脉冲阀#A1的第二端通过列选矩阵控制电路#31与外接电源的正极供电端连通，至此实现对脉冲阀#A1的列定位。经过上述过程，脉冲阀#11的第一端、第二端分别与外接电源的负极供电端、正极供电端连接，脉冲阀#A1得电动作。
在一具体实施例中，如图3所示，行选矩阵控制电路2包括：多个行选控制电路21，其中，每个行选控制电路21的输入端均与控制模块1的一个第一输出端连接，每个行选控制电路21的输出端与一个列选矩阵控制电路3的公共输入端连接。
具体地，本申请实施例的行选控制电路21的数量与仓室脉冲阀组的数量相同，控制模块1通过选通相应的行选控制电路21，使得对应的仓室脉冲阀组内的脉冲阀的第一端与外接电源的负极供电端接通。
示例性地，若布袋除尘器内包括2个仓储脉冲阀组(仓储脉冲阀组#A及仓储脉冲阀组#B)，则行选控制电路21的数量为2个(行选控制电路#21及行选控制电路#22)，其中，行选控制电路#21与仓储脉冲阀组#A对应，行选控制电路#22与仓储脉冲阀组#B对应。
在一具体实施例中，如图4所示，行选控制电路21包括：第一二极管D1及第一熔断器FR1，其中，第一二极管D1的阴极(IN1端)与控制模块1的一个第一输出端连接，第一二极管D1的阳极与第一熔断器FR1的第一端连接，第一熔断器FR1的第二端(OUT1端)与一个列选矩阵控制电路3的公共输入端连接。
具体地，当控制模块1选通行选控制电路21时，该行选控制电路21的第一二极管D1的阴极与外接电源的负极供电端连通，该行选控制电路21的第一熔断器FR1的第二端与该行选控制电路21对应的仓室脉冲阀组内全部的脉冲阀的第一端连通，由此，将选定的仓室脉冲阀组内全部的脉冲阀的第一端与外接电源的负极供电端连通。此外，第一二极管D1反向设置，从而保证工作电流方向只能由行选控制电路21的输出端流向其输入端，电流单向流动，有效防止脉冲阀误动作。
在一具体实施例中，如图5所示，列选矩阵控制电路3包括：公共电路31及多个列选控制电路32。
如图5所示，公共电路31的输入端与行选矩阵控制电路2的第一输出端连接，公共电路31的输出端与一个仓室脉冲阀组的每个脉冲阀的第一端连接；每个列选控制电路32的输入端均与控制模块1的一个第二输出端连接，每个列选控制电路32的输出端与同一个仓室脉冲阀组的一个脉冲阀的第二端连接。
本申请实施例的公共电路31为一条公共线，其直接将公共输入端与公共输出端连通，当公共输入端通过行选控制电路21与外接电源的负极供电端连通后，所对应的仓室脉冲阀组内全部的脉冲阀的第一端通过公共输出端、公共输入端、行选控制电路21与外接电源的负极供电端连通。
本申请实施例的一个列选矩阵控制电路3与一个仓室脉冲阀组对应，列选控制电路32的数量与该仓室脉冲阀组的脉冲阀的数量对应，示例性地，若布袋除尘器内包括2个仓储脉冲阀组(仓储脉冲阀组#A及仓储脉冲阀组#B)，则行选控制电路21的数量为2个(行选控制电路#21及行选控制电路#22)，列选矩阵控制电路3的数量为2个(列选矩阵控制电路#31及列选矩阵控制电路#32)，其中，行选控制电路#21、列选矩阵控制电路#31与仓储脉冲阀组#A对应，行选控制电路#22、列选矩阵控制电路#32与仓储脉冲阀组#B对应。若仓储脉冲阀组#A内包括3个脉冲阀(脉冲阀#A1～脉冲阀#A3)，则列选矩阵控制电路#31包括3个列选控制电路32(列选控制电路#321～列选控制电路#323)，列选控制电路#321～列选控制电路#323分别与脉冲阀#A1～脉冲阀#A3相对应。
基于上述举例，当需要脉冲阀#A1动作时，控制模块1首先将行选控制电路#21的输入端与外接电源的负极供电端连通，至此，脉冲阀#A1～脉冲阀#A3的第一端通过列选矩阵控制电路#31的公共电路31、行选控制电路#21与外接电源的负极供电端连通，实现对脉冲阀#A1的行定位，然后控制模块1将列选控制电路#321的输入端与外接电源的正极供电端连通，至此，脉冲阀#A1的第二端通过列选控制电路#321与外接电源的正极供电端连通，脉冲阀#A1得电动作。
在一具体实施例中，如图6所示，每个列选控制电路32包括：第二二极管D2及第二熔断器FR2，其中，第二二极管D2的阳极与控制模块1的一个第二输出端连接，第二二极管D2的阴极与第二熔断器FR2的第一端连接；第二熔断器FR2的第二端与同一个仓室脉冲阀组的一个脉冲阀的第二端连接。
具体地，本申请实施例的列选控制电路32中设置正向的第二二极管D2，保证工作电流方向只能由输入端流向输出端，电流单向流动，有效防止脉冲阀误动作。并且设置第二熔断器FR2，保证工作电流不过载短路等故障。
具体地，每个列选控制电路32还包括：续流电路，其中，续流电路的第一端与第二二极管D2的阴极连接，续流电路的第二端与公共电路31的输入端、输出端连接。其中，每次脉冲阀开关动作后，续流电路充分释放 脉冲阀动作后存在残余感应电流。
具体地，如图6所示，每个续流电路包括：续流电阻R及续流二极管D3，其中，续流二极管D3的阴极通过续流电阻R与第二二极管D2的阴极连接，续流二极管D3的阳极与公共电路31的输入端、输出端连接。
具体地，本申请实施例的续流回路不仅具有续流功能还具有监控功能，将续流二极管D3为发光二极管，以监控脉冲阀动作状态。
具体地，如图6所示，列选矩阵控制电路3还包括：第三二极管D4，其中，第三二极管D4的阳极与公共电路31的输入端、输出端连接，第三二极管D4的阴极与每个续流电路的第二端连接。
在一具体实施例中，如图7所示，布袋除尘器脉冲阀的控制电路还包括：供电电源4，供电电源4的两个供电端与控制模块1的两个输入端对应连接。其中，供电电源4的功能等同于上述外接电源，在此不再赘述。
本申请实施例提供的布袋除尘器脉冲阀的控制电路，可以通过固化封装二极管印刷电路模块化，使得矩阵式控制电路结构简单，安装检修替换方便可靠，具有防尘、防振、防水功能更加适应布袋除尘器应用环境。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引申出的显而易见的变化或变动仍处于本申请创造的保护范围之中。
