Description

一种便于调节流量的锅炉旁路烟道组件及其使用方法 技术领域
本发明涉及火力发电技术领域，尤其涉及一种便于调节流量的锅炉旁路烟道组件及其使用方法。
 背景技术
火力发电，利用可燃物在燃烧时产生的热能，通过发电动力装置转换成电能的一种发电方式。火力发电按其作用分单纯供电的和既发电又供热的。按原动机分汽轮机发电、燃气轮机发电、柴油机发电。按所用燃料分，主要有燃煤发电、燃油发电、燃气发电。为提高综合经济效益，火力发电应尽量靠近燃料基地进行。火力发电中存在着三种型式的能量转换过程：燃料化学能→蒸汽热能→机械能→电能简单的说就是利用燃料发热，加热水，形成高温高压过热蒸汽，然后蒸汽沿管道进入汽轮机中不断膨胀做功，冲击汽轮机转子高速旋转，带动发电机转子（电磁场）旋转，定子线圈切割磁力线，发出电能，再利用升压变压器，升到系统电压，与系统并网，向外输送电能。最后冷却后的蒸汽又被给水泵进一步升压送回锅炉中重复参加上述循环过程。
现有的锅炉旁路烟道，在工作时，无法做到对烟气流量的调节，并且无法做到对烟气中的灰尘及油污进行有效的处理，会使得烟气中的油污进入脱硝装置内部，对脱硝装置的使用寿命造成影响，造成了一定程度的资源浪费，给电厂的使用带来麻烦，为此我们提出一种便于调节流量的锅炉旁路烟道组件及其使用方法来解决上述问题。
发明内容
本发明的目的是为了解决现有技术中无法做到对烟气流量的调节，并且无法做到对烟气中的灰尘及油污进行有效的处理，会使得烟气中的油污进入脱硝装置内部，对脱硝装置的使用寿命造成影响，造成了一定程度的资源浪费，给电厂的使用带来麻烦的问题，而提出的一种便于调节流量的锅炉旁路烟道组件及其使用方法。
为了实现上述目的，本发明采用了如下技术方案：
一种便于调节流量的锅炉旁路烟道组件，包括：
管道，所述管道的侧壁安装有流量调节挡板，所述管道的内侧壁安装有清理装置；
驱动装置，所述驱动装置用于驱动所述清理装置工作，所述驱动装置设置在所述管道的内侧壁；
过滤组件，所述过滤组件用于对烟气进行处理，所述过滤组件设置在所述管道的内侧壁；

优选地，所述清理装置包括液管、波纹管、撞击板、喷口、复位弹簧和连接板；所述液管与所述管道的侧壁通过轴承相连接，所述液管的外侧壁与所述连接板的端部固定连接，所述液管与所述撞击板通过所述波纹管相连接，所述撞击板的外侧壁与所述连接板的内侧壁滑动连接，所述复位弹簧的端部与所述撞击板的底部固定连接，所述复位弹簧的端部与所述液管的外侧壁固定连接，所述喷口开设在所述撞击板的端部。
优选地，所述驱动装置包括叶片和转轴；所述叶片的端部与所述转轴的外侧壁固定连接，所述叶片的侧壁与所述管道的内侧壁相贴合，所述转轴的端部与所述管道的侧壁通过轴承相连接。
优选地，所述过滤组件包括滤筒、通孔和挤压板；所述滤筒的端部与所述管道的侧壁通过轴承相连接，所述通孔贯穿所述滤筒的侧壁，所述挤压板的端部与所述滤筒的内侧壁固定连接。
优选地，所述传动组件包括主动皮带轮、皮带和从动皮带轮；所述主动皮带轮的内侧壁与所述驱动装置的输出轴固定连接，所述皮带的内侧壁与所述主动皮带轮的外侧壁相贴合，所述从动皮带轮的内侧壁与所述过滤组件的外侧壁固定连接，所述从动皮带轮的外侧壁与所述主动皮带轮的内侧壁相贴合。

优选地，所述挤压板的侧壁与所述撞击板的端部相贴合。
一种便于调节流量的锅炉旁路烟道使用方法，其步骤如下所述：
根据需要进入烟气的量自动调节流量调节挡板的大小，这时烟气管道开始进入烟气；
通过烟气的流动带动叶片转动，叶片的转动将会通过转轴带动传动组件工作；
通过传动组件的工作带动滤筒转动，滤筒通过传动齿轮带动清理装置进行工作，使得滤筒正转，对灰尘和油污进行过滤，清理装置反转；
清理装置的反转使得液管的转动在离心力的作用下，将液箱内的乳化液通过液管经过波纹管流入撞击板内，最后经过喷口喷向滤筒的内侧壁，实现对烟气内油污的乳化；
在滤筒转动的过程中，由于滤筒的正转和清理装置的反转，使得挤压板能够挤压撞击板向内滑动，在挤压板无法挤压撞击板时，撞击板将会在复位弹簧的作用下向外移动，使得撞击板撞击滤筒，使得被乳化后的油污和灰尘振动掉落；
在脱硝入口烟气温度达到要求后，控制关断型挡板对管道进行关闭。
相比现有技术，本发明的有益效果为：
1、本发明通过管道开始进入烟气时，通过烟气的流通带动叶片进行转动，进而带动转轴转动，通过转轴的转动经过传动组件带动滤筒转动，滤筒的转动将会通过传动齿轮带动液管反向转动，滤筒的转动实现对烟气中的灰尘以及油污进行过滤，液管的转动将会带动连接板转动，使得撞击板始终与滤筒的内侧壁相贴合，并且由于液管和撞击板的转动，使得液管和撞击板内的乳化剂在离心力的作用下经过喷口喷向滤筒，实现对滤筒粘附的油污进行乳化功能，防止油污堆积在滤筒的外表面，导致滤筒的堵塞影响管道的功能，使得管道能够长时间稳定工作。
2、本发明由于滤筒的转动带动液管的反转，在滤筒的内侧壁设置的挤压板与撞击板的端部相互挤压时，将会使得撞击板沿连接板的内侧壁向内滑动，当挤压板无法在此挤压撞击板时，撞击板将会在复位弹簧和离心力的作用下撞击滤筒，使得滤筒粘附的灰尘以及经过乳化剂乳化的油污能够在滤筒的振动下，滴落下来，并且经过滤筒的旋转离心力使得滤筒上粘附的乳化后的油污快速甩下，实现了对经过管道内的烟气的净化，防止经过管道排出的烟气对脱硝装置的脱硝效率及使用寿命造成影响，保证了脱硝装置的稳定工作，节约了资源。
3、在需要对烟气的流量进行调节时，通过控制流量调节挡板便可实现对烟气流量的调节，低负荷工况可通过调节其开度增加适当的烟气阻力，以保证足够的烟气流入旁路烟道，以保证进入脱硝装置入口烟气温度能够达到要求。

一种便于调节流量的锅炉旁路烟道使用方法，其步骤如下：
根据需要进入烟气的量自动调节流量调节挡板2的大小，这时烟气管道1开始进入烟气；
通过烟气的流动带动叶片51转动，叶片51的转动将会通过转轴52带动主动皮带轮61转动，进而通过皮带62带动从动皮带轮63转动；
通过从动皮带轮63的转动带动滤筒81转动，滤筒81通过传动齿轮7带动清理装置9进行工作，使得滤筒81正转，对灰尘和油污进行过滤，液管91反转；
清理装置9的反转使得液管91的转动在离心力的作用下，将液箱4内的乳化液通过液管91经过波纹管92流入撞击板93内，最后经过喷口94喷向滤筒81的内侧壁，实现对烟气内油污的乳化；
在滤筒81转动的过程中，由于滤筒81的正转和清理装置9的反转，使得挤压板83能够挤压撞击板93向内滑动，在挤压板83无法挤压撞击板93时，撞击板93将会在复位弹簧95的作用下向外移动，使得撞击板93撞击滤筒81，使得被乳化后的油污和灰尘振动掉落；
在脱硝入口烟气温度达到要求后，控制关断型挡板3对管道1进行关闭，此时流量调节挡板2处于关闭状态。
