沥青拌和设备(沥青混合料搅拌设备)的主要生产工艺流程包括：冷骨料的上料输送装置为烘干装置持续输送初配的冷骨料，烘干装置和主除尘装置为设备提供混合料核心物质-热骨料，热骨料经热骨料提升装置送至位于主楼最上层的热骨料筛分装置，分选后的热骨料按粒径大小分别存储于各热骨料仓，热骨料、沥青和矿粉分别计量后加入搅拌装置，搅拌后的成品料则存入成品仓，等待装车区的装卸车放料运输。在这些生产环节中，会产生粉尘或沥青烟等污染源，其中尤其在非封闭的冷骨料的上料和输送(冷骨料上料输送装置)、热骨料的筛分和存储(热骨料筛分存储装置)、热骨料的计量(骨料计量装置)、沥青供给(沥青供给装置)、混合物的搅拌(搅拌装置)以及成品料的存储和装卸(成品仓和装车区)等环节，所产生的粉尘或沥青烟容易发生逸散，对空气质量及人体健康危害较大。
目前已采取一些措施来减少沥青拌和设备排放物的危害，然而，这些措施通常对粉尘和沥青烟分别进行处理，结构复杂，功能冗余，现场改造成本较高，并且，其中对沥青烟的处理，一般仅对装车区的沥青烟进行处理，且仅能较为有效地去除沥青烟中的油滴和VOC(Volatile Organic Compounds，挥发性有机化合物)中的一种，而难以同时有效地去除油滴和VOC，净化效果有限。

沥青烟捕集装置22，用于捕集沥青供给装置14、搅拌装置16及成品处理装置17中的至少一个所逸散的沥青烟；
混合装置25，入口与粉尘捕集装置21的出口和沥青烟捕集装置22的出口均连通，并用于供粉尘捕集装置21所捕集的粉尘及沥青烟捕集装置22所捕集的沥青烟在其中混合；和
第一净化装置26，入口与混合装置25的出口连通，并用于除去由混合装置25流出的气体中的颗粒物，颗粒物包括粉尘及粉尘与沥青烟油滴的结合物。
基于上述设置，净化设备2可以分别利用粉尘捕集装置21和沥青烟捕集装置22实现对所利用粉尘和待净化沥青烟的捕集，而所捕集的粉尘可以在混合装置25中与所捕集的沥青烟结合，对沥青烟中的油滴进行粘附包裹，将油滴转化为可过滤净化的“固态化”颗粒物，且粉尘和转化成的“固态化”颗粒物可以进一步进入第一净化装置26中，被第一净化装置26除去，从而实现对所逸散粉尘的回收利用，以及对所逸散沥青烟中油滴的有效净化。
由于只需利用同一第一净化装置26，即可同时实现对所捕集粉尘和所捕集沥青烟中油滴的去除，而无需分别设置不同的净化装置来除去粉尘和沥青烟油滴，因此，不至于因为净化装置数量较多而造成功能冗余，结构较为简单，成本也较低。
在另一些实施方式中，净化设备2可以还包括粉尘监测装置23，粉尘监测装置23用于监测粉尘捕集装置21所捕集粉尘的参数。其中，所捕集粉尘的参数可以包括所捕集粉尘的浓度、流速或压力等中的一个或多个。这样，可以在利用所捕集的粉尘净化所捕集的沥青烟的过程中，及时地了解粉尘的捕集情况，方便准确地确定所捕集粉尘的总量。
而在又一些实施方式中，净化设备2也可以包括沥青烟监测装置24，沥青烟监测装置24用于监测沥青烟捕集装置22所捕集沥青烟的参数。其中，所捕集沥青烟的参数可以包括所捕集沥青烟的浓度、流速或压力等中的一个或多个。这样，可以在利用所捕集的粉尘净化所捕集的沥青烟的过程中，及时地了解沥青烟的捕集情况，方便准确地确定所捕集沥青烟的总量。
或者，净化设备2还可以同时包括粉尘监测装置23和沥青烟监测装置24，基于此，不仅可以确定所捕集粉尘总量，同时也可以确定所捕集沥青烟总量，这样，便于基于监测结果确定所捕集粉尘总量是否满足所捕集沥青烟总量的净化需求，进而便于在所捕集粉尘总量无法满足所捕集沥青烟总量的净化需求时，采取进一步的措施。
例如，本公开的净化设备2可以在包括粉尘监测装置23和沥青烟监测装置24的同时，还包括补粉装置2a，补粉装置2a用于根据粉尘监测装置23和沥青烟监测装置 24的监测结果，在粉尘捕集装置21所捕集的粉尘总量无法满足沥青烟捕集装置22所捕集的沥青烟总量的需求时，向混合装置25中补充粉尘。该补粉过程可以在沥青拌和系统的控制装置2b的控制下完成。基于此，本公开可以更可靠地利用粉尘实现对所捕集沥青烟中油滴的充分净化。
其中，为了方便确定所捕集粉尘总量是否满足所捕集沥青烟总量的需求，在基于监测结果判断所捕集粉尘总量是否满足所捕集沥青烟总量的需求之前，还可以预先建立沥青烟总量与净化沥青烟所需粉尘总量之间的对应关系表，且在判断所捕集粉尘总量是否满足所捕集沥青烟总量的需求时，基于监测结果和对应关系表来判断所捕集粉尘总量是否满足所捕集沥青烟总量的需求。而在基于监测结果和对应关系表来判断所捕集粉尘总量是否满足所捕集沥青烟总量的需求时，可以基于监测结果确定所捕集粉尘总量和所捕集沥青烟总量，并根据所确定的所捕集沥青烟总量，在对应关系表中确定所需要的粉尘总量，且比较所需要的粉尘总量与所捕集的粉尘总量，若需要的粉尘总量大于所捕集的粉尘总量，则判断所捕集的粉尘总量无法满足所捕集沥青烟总量的需求。
另外，为了实现对沥青烟更好的净化效果，本公开的净化设备2可以被构造为不仅能够净化沥青烟中的油滴，还能够净化沥青烟中的VOC气体。例如，在一些实施方式中，净化设备2可以还包括第二净化装置27，第二净化装置27的入口与第一净化装置26的出口连通，并用于净化由第一净化装置26流出的气体中的VOC气体。通过在第一净化装置26的下游进一步设置第二净化装置27，本公开可以既实现对粉尘和沥青烟油滴的净化，又实现对沥青烟中VOC气体的净化，从而实现对沥青拌和设备1排放物的固-液-气三相净化，有效改善净化效果。
下面结合图1-4所示的各实施例对本公开予以进一步地说明。
首先，结合图1所示的实施例予以说明。
如图1所示，在该实施例中，沥青拌和系统包括沥青拌和设备1和净化设备2，净化设备2连通沥青拌和设备1和烟囱3，用于对沥青拌和设备1的粉尘和沥青烟等排放物进行净化。
沥青拌和设备1(或称沥青混合料搅拌设备)用于在规定的温度下将干燥加热的不同粒径骨料、填料和沥青等按照设计配比混合搅拌成均匀的混合料，其包括冷骨料上料输送装置11、烘干装置(图中未示出)、主除尘装置(图中未示出)、热骨料提升装置(图中未示出)、热骨料筛分存储装置12、沥青供给装置14、计量装置13、 搅拌装置16和成品处理装置17等。
其中，冷骨料上料输送装置11用于实现冷骨料的上料和输送，其包括冷料斗111和冷料输送装置112，冷料输送装置112用于将冷料斗111中的冷骨料输送至烘干装置。冷料输送装置112例如可以包括冷料输送皮带机构等。
烘干装置用于对冷骨料进行加热和烘干。烘干装置例如可以包括干燥滚筒，干燥滚筒可以以逆流加热的方式将冷骨料加热烘干到一定温度。
主除尘装置用于对烘干装置排出的高温含尘烟气进行一定的净化，净化后的烟气通常排入大气，且主除尘装置还可以用于收集烘干装置排出的粗粉，所收集的粗粉与由烘干装置流向热骨料提升装置的细粉一起，被热骨料提升装置提起。
热骨料提升装置用于将由烘干装置和主除尘装置所提供的热骨料输送至位于主楼顶层的热骨料筛分装置121。
热骨料筛分存储装置包括热骨料筛分装置121和热骨料仓122，分别用于对热骨料进行筛分和存储，以便于按照不同规格进行存储。例如，热骨料筛分装置121可以将热骨料筛分为5种规格，并分别存入五个热骨料仓122中。热骨料筛分装置121可以包括振动筛。
生产沥青混合料，除了需要骨料，还需要沥青和粉料等。沥青供给装置14即用于提供所需要的沥青，其包括重油储罐142和沥青储罐141，分别存储重油和沥青。重油储罐142和沥青储罐141需要被加热，以提供热沥青。
存储于热骨料仓122中的热骨料，以及沥青供给装置14所提供的热沥青和粉料供给装置所提供的粉料，在被搅拌装置16搅拌之前，还需进行称量，以满足设定配比的要求。计量装置13即用于称量热骨料、沥青和粉料等，其包括骨料计量装置131、沥青计量装置(图中未示出)和粉料计量装置(图中未示出)等，以分别实现对热骨料、沥青和粉料的称重。
经过称重的热骨料、沥青和粉料，依据事先设定的顺序投入到搅拌装置16中，被搅拌装置16搅拌均匀，形成混合料，即成品料。
成品处理装置17对成品料进行后处理。例如，成品处理装置17可以包括成品仓171，以实现对成品料的存储；或者，也可以包括装车区172，以对成品料进行装车外运。
在沥青拌和设备1的上述各装置中，冷骨料上料输送装置11、热骨料筛分存储装置12和计量装置13均会逸散较多的粉尘，而沥青供给装置14、搅拌装置16和成品 处理装置17均会逸散较多的沥青烟。
为了减少沥青拌和设备1排放物的危害，目前通常对所逸散的粉尘和沥青烟分别进行处理，其中，一般单独设置表面预涂粉尘或吸附剂的除尘器，利用除尘器表面预涂的粉尘或吸附剂来去除沥青烟中的油滴，而所逸散的粉尘则采用其他的净化装置进行净化，这一方面造成净化装置较多，结构复杂，装置冗余；另一方面，粉尘和油滴的净化效果受到一定的限制，净化效率也较低；又一方面，在粉尘或吸附剂吸附饱和时，经常需要停机补粉或吸附剂，这种间歇作业模式，难以适应沥青拌和设备1长时间持续作业的工况；再一方面，沥青烟中的VOC气体并未得以处理。
有鉴于此，该实施例将为沥青拌和设备1所配备的净化设备2构造为能够利用沥青拌和设备1自身所逸散的粉尘来净化沥青拌和设备1所逸散的沥青烟中的油滴，并对沥青烟中的VOC气体进行净化。
具体地，如图1所示，在该实施例中，净化设备2包括粉尘捕集装置21、沥青烟捕集装置22、混合装置25、第一净化装置26、第二净化装置27和驱动装置28等。
其中，驱动装置28用作整个净化设备2的动力设备，其为粉尘和气体等的流动提供动力，方便沥青拌和设备1排出的粉尘和气体等经由净化设备2流向烟囱3。驱动装置28可以包括风扇等吹风装置或引风机281等引风装置，其中引风装置可以提供更充足的动力，驱动实现更顺畅的流动过程。当驱动装置28包括引风装置时，引风装置可以布置于第一净化装置26的下游并与第一净化装置26的出口连通。由图1可知，在该实施例中，驱动装置28的入口通过第二净化装置27与第一净化装置26的出口连通，且驱动装置28的出口通过烟囱3与大气连通，这样，在驱动装置28的作用下，沥青拌和设备1所排放的粉尘和沥青烟可以分别顺利地被粉尘捕集装置21和沥青烟捕集装置22所捕集，并均能够顺利地流入混合装置25，并进一步被第一净化装置26和第二净化装置27净化，之后净化后的烟气也可以流入空气中。
粉尘捕集装置21用于捕集沥青拌和设备1所排放的粉尘，供净化沥青烟所需。由图1可知，在该实施例中，粉尘捕集装置21的入口与冷骨料上料输送装置11、热骨料筛分存储装置12和计量装置13均连通，用于对冷骨料上料输送装置11、热骨料筛分存储装置12和计量装置13所逸散的粉尘进行捕集，且粉尘捕集装置21的出口通过粉尘输送管路29a与混合装置25连通，以将所捕集的粉尘输送至混合装置25中。
由于如前所述，冷骨料上料输送装置11、热骨料筛分存储装置12和计量装置13为沥青拌和设备1粉尘逸散较多的部位，因此，该实施例的粉尘捕集装置21对这几 处均进行粉尘捕集，可以实现对沥青拌和设备1所逸散粉尘较充分地回收利用，减少粉尘的无组织排放。
沥青烟捕集装置22用于对沥青拌和设备1所排放的沥青烟进行捕集，以待净化。由图1可知，在该实施例中，沥青烟捕集装置22的入口与沥青供给装置14、搅拌装置16和成品处理装置17均连通，用于对沥青供给装置14、搅拌装置16和成品处理装置17所逸散的沥青烟进行捕集，且沥青烟捕集装置22的出口通过沥青烟输送管路29b与混合装置25连通，以将所捕集的沥青烟输送至混合装置25中，与粉尘混合。
由于如前所述，沥青供给装置14、搅拌装置16和成品处理装置17为沥青拌和设备1沥青烟逸散较多的部位，因此，该实施例的沥青烟捕集装置22对这几处均进行沥青烟捕集，相对于仅对成品处理装置17的装车区172的沥青烟进行捕集的情况，可以实现对沥青拌和设备1所逸散沥青烟更充分地捕集和净化，更有效地减少沥青烟的无组织排放，且净化设备2的利用率也较高。
粉尘捕集装置21或沥青烟捕集装置22可以通过使目标保持于微负压状态，来实现对粉尘或沥青烟的捕集。
混合装置25用于实现粉尘和沥青烟的混合，以使粉尘能够与沥青烟中的油滴结合，将油滴转化为可净化的“固态化”颗粒物，方便第一净化装置26净化。由图1可知，在该实施例中，混合装置25布置于粉尘捕集装置21及沥青烟捕集装置22与第一净化装置26之间，其入口与粉尘捕集装置21的出口和沥青烟捕集装置22的出口均连通，同时，其出口与第一净化装置26的入口连通。基于此，粉尘捕集装置21所捕集的粉尘以及沥青烟捕集装置22所捕集的沥青烟均能够流入混合装置25中，并不断混合，使得粉尘颗粒物与沥青烟油滴发生粘附作用，粉尘对整个油滴进行包裹，这不仅可以实现对粉尘的初步去除，还可以将油滴转化为可过滤净化的“固态化”颗粒物，实现对沥青烟中液体有害物的去除，且沥青烟油滴被包裹后的混合气体可以进一步流入第一净化装置26中，被第一净化装置26净化。
第一净化装置26用于去除粉尘和被粉尘包裹的油滴等固态物质，以对由混合装置25流出的气体进行一次净化。由图1可知，在该实施例中，第一净化装置26布置于混合装置25与第二净化装置27之间，其入口与混合装置25的出口连通，且其出口与第二净化装置27的入口连通。基于此，由混合装置25流出的携带粉尘和由油滴转化而来的“固态化”颗粒物在气流的作用下可以进入第一净化装置26中，由该第一净化装置26除去粉尘和由油滴转化而来的“固态化”颗粒物，进一步过滤排放物 中的固态颗粒物，该过程为干式净化过程，无二次污染，且能自动清灰；而被第一净化装置26净化后的烟气可以进一步流入第二净化装置27中，被第二净化装置27净化。
第二净化装置27用于去除烟气中的VOC气体，通过净化烟气中的致癌及恶臭气体，来对由混合装置25流出的气体进行再一次净化。如图1所示，在该实施例中，第二净化装置27布置于第一净化装置26与驱动装置28之间，其入口与第一净化装置26的出口连通，且其出口与驱动装置28的入口连通。基于此，经第一净化装置26净化过的烟气可以流入第二净化装置27中，由该第二净化装置27过滤其中的致癌及恶臭气体，实现对排放物中气态有害物的去除，且过滤净化后的气体可以在驱动装置28的作用下经由烟囱3排入大气中。
可见，通过设置粉尘捕集装置21、沥青烟捕集装置22、混合装置25、第一净化装置26、第二净化装置27和驱动装置28，该实施例的净化设备2能够利用所捕集的沥青拌和设备1自身在冷骨料上料输送、热骨料筛分存储、以及计量等工艺流程中所产生的粉尘来净化沥青加热、混合料搅拌及放料过程中所逸散的沥青烟，工艺简单，油滴去除率高，也无二次污染，且在混合装置25、第一净化装置26和第二净化装置27的配合作用下，净化设备2能够对排放物实施固-液-气三相净化，对沥青拌和设备1全工艺流程进行较全面且较彻底地净化，有效控制粉尘、烟尘、沥青烟油滴和气态VOC的有组织排放和无组织排放，减少排放物对环境及人员健康的危害，实现沥青混合料绿色环保的生产过程。
另外，如图1所示，为了因防止所捕集的粉尘无法满足所捕集沥青烟的净化需求而影响对沥青烟的净化效果，该实施例的净化设备2中还设有粉尘监测装置23、沥青烟监测装置24和补粉装置2a，粉尘监测装置23、沥青烟监测装置24和补粉装置2a在控制装置2b的控制下，协调工作，以在所捕集的粉尘无法满足所捕集沥青烟的净化需求时，及时响应。
具体地，由图1可知，在该实施例中，粉尘监测装置23和沥青烟监测装置24分别设置在粉尘输送管路29a和沥青烟输送管路29b中，并分别用于监测粉尘捕集装置21所捕集粉尘及沥青烟捕集装置22所捕集沥青烟的浓度、流速及压力等参数；补粉装置2a与混合装置25连通，用于向混合装置25中补充粉尘；控制装置2b则与粉尘监测装置23、沥青烟监测装置24和补粉装置2a均电连接，其基于粉尘监测装置23和沥青烟监测装置24的监测结果，判断粉尘捕集装置21所捕集的粉尘总量是否满足 沥青烟捕集装置22所捕集的沥青烟总量的需求，并在粉尘捕集装置21所捕集的粉尘总量无法满足沥青烟捕集装置22所捕集的沥青烟总量的需求时，控制补粉装置2a向混合装置25中补充粉尘。基于此，可以使净化设备2能够更可靠地实现对所捕集沥青烟的充分净化。且由于无需停机补粉，因此，能够更好地适应沥青拌和设备1长时间持续作业的工况。
其中，粉尘监测装置23或沥青烟监测装置24可以包括激光监测装置、滤膜过滤装置等，实现对粉尘或沥青烟的实时监测。补粉装置2a可以包括粉罐和喷吹系统等。而补给粉则可以来源于烘干滚筒除尘器回收粉或抑烟剂等亲油属性固体颗粒物粉末(粒径≤75μm)。
更具体地，参照图5，可以预先建立沥青烟总量与净化全部沥青烟所需粉尘总量之间的对应关系表，并将该对应关系表存储于控制装置2b中，并且，控制装置2b中可以同时存储粉尘输送管路29a和沥青烟输送管路29b的截面积；工作过程中，由粉尘监测装置23和沥青烟监测装置24分别监测当前时刻输送管路内粉尘和沥青烟的浓度、流速、压力等参数，进而控制装置2b根据公式：单位时间回收颗粒物总量＝浓度*流速*截面积，来计算粉尘输送管路29a内单位时间回收粉尘颗粒物总量及沥青烟输送管路29b内单位时间回收沥青烟总量；根据沥青烟输送管路29b内单位时间回收沥青烟总量，在沥青烟总量与净化所需粉尘总量之间的对应关系表中确定净化当前时刻沥青烟总量所需要的粉尘总量，判断粉尘输送管路29a内单位时间回收粉尘总量是否小于净化当前时刻沥青烟总量所需要的粉尘总量，如果判断为否，则继续监测；如果判断为是，则计算净化当前时刻沥青烟总量所需要的粉尘总量与粉尘输送管路29a内单位时间回收粉尘总量之差，并传递补给信号至补粉装置2a，控制补粉装置2a喷入不足的粉尘量，以使在所捕集粉尘和所补充粉尘的共同作用下，能够较为彻底地去除沥青烟中的油滴。
接下来结合图2-4所示的实施例予以说明。为了简化描述，以下仅对这几个实施例与图1所示实施例及这几个实施例彼此之间的不同之处进行说明。
在图2所示的实施例中，粉尘捕集装置21仅包括第一粉尘捕集装置211，该第一粉尘捕集装置211用于捕集冷骨料上料输送装置11所逸散的粉尘，且该第一粉尘捕集装置211与冷骨料上料输送装置11的冷料斗111和冷料输送装置112均连通，用于捕集冷料斗111和冷料输送装置112所逸散的粉尘。基于此，该实施例的粉尘捕集装置21仅捕集热骨料上料输送装置11所逸散的粉尘，且在捕集热骨料上料输送装置11 所逸散的粉尘时，同时捕集冷料斗111和冷料输送装置112所逸散的粉尘。
该第一粉尘捕集装置211的出口通过第一粉尘输送管路291与混合装置25连通。
相应地，在该实施例中，粉尘监测装置23仅包括第一粉尘监测装置231，用于监测第一粉尘捕集装置211所捕集粉尘参数。由图2可知，该第一粉尘捕集装置211设置于第一粉尘输送管路291中。
另外，在该实施例中，沥青烟捕集装置22包括第一沥青烟捕集装置221和第二沥青烟捕集装置222，第一沥青烟捕集装置221用于捕集沥青供给装置14所逸散的沥青烟，而第二沥青烟捕集装置222用于捕集搅拌装置16及成品处理装置17中的至少一个所逸散的沥青烟。
具体地，由图2可知，第一沥青烟捕集装置221的入口与沥青供给装置14的沥青储罐141和重油储罐142(具体为沥青储罐141和重油储罐142的呼吸口)均连通，同时，其出口通过第一沥青烟输送管路293与混合装置25连通；而第二沥青烟捕集装置222则入口与搅拌装置16和成品处理装置17的成品仓171和装车区172均连通，同时其出口通过第二沥青烟输送管路294与混合装置25连通。基于此，该实施例的沥青烟捕集装置22，可以分别通过第一沥青烟捕集装置221和第二沥青烟捕集装置222，来实现对沥青加热和混合料搅拌及成品料放料装车等环节所逸散沥青烟的捕集。
相应地，为了实现对第一沥青烟捕集装置221及第二沥青烟捕集装置222所捕集沥青烟参数的监测，如图2所示，在该实施例中，沥青烟监测装置24包括第一沥青烟监测装置241和第二沥青烟监测装置242，且二者分别设置于第一沥青烟输送管路293和第二沥青烟输送管路294中。这种情况下，在确定所捕集沥青烟总量时，需要基于第一沥青烟监测装置241和第二沥青烟监测装置242的结果来确定，其中可以把第一沥青烟监测装置241所监测到的浓度和流速与第一沥青烟输送管路293的截面积相乘，得到第一沥青烟捕集装置221所捕集的沥青烟总量，并把第二沥青烟监测装置242所监测到的浓度和流速与第二沥青烟输送管路294的截面积相乘，得到第二沥青烟捕集装置222所捕集的沥青烟总量，再将第一沥青烟捕集装置221所捕集的沥青烟总量与第二沥青烟捕集装置222所捕集的沥青烟总量相加，得到最终的所捕集沥青烟总量。
此外，与图1所示实施例的不同之处还在于，在该实施例中，第一净化装置26、第二净化装置27及驱动装置28分别被具体实施为除尘器261、VOC净化机271和引风机281。除尘器261可以选用布袋除尘器、滤筒除尘器、塑烧板除尘器、电除尘器 或电袋复合除尘器等。
利用同一除尘器261来对粉尘和沥青烟进行净化，相对于针对粉尘和沥青烟分别设置不同的除尘器的情况，可以有效简化结构，减少装置冗余，降低成本。并且，单独设置一除尘器261作为第一净化装置26，而不将主除尘器兼用作第一净化装置26，可以减少净化设备2对沥青拌和设备1正常生产流程的影响。同时，不捕集烘干除尘环节所产生的粉尘，也可以更好地适应烘干除尘环节需要稳定风量风压配比的特点。
图3所示实施例与图2所示实施例的主要不同之处在于，粉尘捕集装置21和粉尘监测装置23的结构不同。
其中，在该实施例中，粉尘捕集装置21不再包括第一粉尘捕集装置211，而仅包括第二粉尘捕集装置212，该第二粉尘捕集装置212用于捕集热骨料筛分存储装置12和计量装置13中的至少一个所逸散的粉尘。具体地，如图3所示，该实施例的第二粉尘捕集装置212，其入口与热骨料筛分存储装置12的热骨料筛分装置121和热骨料仓122以及计量装置13的骨料计量装置131均连通，同时其出口通过第二粉尘输送管路292与混合装置25连通。基于此，该实施例的粉尘捕集装置21对热骨料筛分存储装置12和计量装置13所逸散的粉尘均进行捕集，却不再捕集热骨料上料输送装置11所逸散的粉尘，且在捕集热骨料筛分存储装置12和计量装置13所逸散的粉尘时，同时捕集热骨料筛分装置121、热骨料仓122和骨料计量装置131所逸散的粉尘。
而相应地，该实施例的粉尘监测装置23不再包括第一粉尘监测装置231，而仅包括第二粉尘监测装置232，该第二粉尘监测装置232设置在第二粉尘输送管路292中，用于监测第二粉尘捕集装置212所捕集粉尘的参数。
图4所示实施例与图2和图3所示实施例的不同之处主要在于，在该实施例中，粉尘捕集装置21同时包括第一粉尘捕集装置211和第二粉尘捕集装置212，且粉尘监测装置23同时包括第一粉尘监测装置231和第二粉尘监测装置232。这种情况下，在确定所捕集粉尘总量时，需要基于第一粉尘监测装置231和第二粉尘监测装置232的结果来确定，其中可以把第一粉尘监测装置231所监测到的浓度和流速与第一粉尘输送管路291的截面积相乘，得到第一粉尘捕集装置211所捕集的粉尘总量，并把第二粉尘监测装置232所监测到的浓度和流速与第二粉尘输送管路292的截面积相乘，得到第二粉尘捕集装置212所捕集的粉尘总量，再将第一粉尘捕集装置211所捕集的粉尘总量与第二粉尘捕集装置212所捕集的粉尘总量相加，得到最终的所捕集粉尘总量。
以上所述仅为本公开的示例性实施例，并不用以限制本公开，凡在本公开的精神 和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
