Description

水泥窑窑尾及旁路放风余热锅炉 技术领域
发明涉及水泥熟料生产线纯中低温余热回收领域，更具体地涉及一种水泥窑窑尾及旁路放风余热锅炉。
背景技术
水泥企业是国民经济生产中的能源消耗大户，水泥行业已被列为国家节约资源的重点领域之一。在国务院提出加快建设节约型社会的政策背景下，提高水泥行业的节约型制造和应用水平，建立节约型水泥工业体系意义重大。在当前国内外能源供需矛盾突出的情况下，节能降耗已成为水泥行业必须完成的课题，水泥窑纯中低温余热回收技术使这个问题得以很好的解决。在水泥窑纯中低温余热回收领域，余热锅炉是关键性设备，而余热锅炉的设计更是重中之重，其不仅关系到水泥窑余热回收系统对水泥生产线余热的回收效率，同时也关系到余热回收系统能否长期稳定高效运行。
在水泥生产过程中，由窑尾预热器排出的烟气，品位低，流量大，含尘浓度高，废气中粉尘浓度较大(约100g/Nm 3)，且粉尘的粘附性较强。为了回收该低品位的废气余热，在窑尾设置了窑尾余热锅炉(简称SP炉)。由水泥窑窑尾烟室取出的旁路放风烟气，品味相对较高，流量中等，含尘浓度高，废气中粉尘浓度极大(约500g/Nm 3)，且粉尘的粘附性较强。旁路放风烟气作为一种新的节能回收模式，被应用于生产实践中，在窑尾设置了旁路放风余热锅炉(简称PH炉)。余热烟气中含有大量的粉尘，当烟气通过余热锅炉进行热交换时，将不同程度的附着在锅炉传热面管的表面而阻碍热传递降低余热锅炉热效率；同时烟气在余热锅炉内流动的沿程阻力增大，从而额外增加二次能源消耗。
目前水泥窑窑尾及旁路放风余热锅炉，大多采用立式锅炉，立式锅炉的传热面管采用水平横排布置，此种结构传热面管外表面容易积灰，积灰较多后会降低锅炉传热面管换热效率。
发明内容
本发明针对现有技术的不足，提供一种水泥窑窑尾及旁路放风余热锅炉，其将传热面管由现有技术中水平横排布置改变为垂直竖排布置，并在该竖排布置的传热面管底部配装振打除灰装置，使得传热面管在竖向为一整体；由此可知：本发明在传热面管底部施加振打，即可使得传热面管表面的积灰从上到下依次跌落，有效地降低传热面管的表面积灰，从而维持传热面管长期工作过程中的传热效率稳定性。
为实现以上的技术目的，本发明将采取以下的技术方案：
一种水泥窑窑尾及旁路放风余热锅炉，包括呈立式结构布置的锅炉本体、设置于锅炉本体烟道内的传热面管以及传热面管所配装的振打除灰装置，所述的传热面管以竖排方式布置于锅炉本体烟道内，各传热面管在竖向一体设置，而振打除灰装置设置在传热面管竖直方向的底部或者靠近传热面管竖直方向的底部设置。
作为本发明的进一步改进，本发明所述传热面管悬挂安装在通风梁上，而通风梁的两端分别与用于支撑锅炉本体的锅炉钢架连接，以使通风梁横跨地设置在锅炉本体烟道内；所述传热面管的平面延展方向与锅炉钢架的长度延伸方向相平行。
作为本发明的进一步改进，本发明所述传热面管通过悬吊机构悬挂安装在通风梁上；该悬吊机构包括吊座、连接板以及轴组件；吊座与通风梁固定连接，连接板一端通过轴组件与吊座连接，另一端则通过轴组件与用于夹持安装传热面管的夹马装置连接。
作为本发明的进一步改进，本发明所述的悬吊机构为两组，振打除灰装置为一个；且振打除灰装置沿锅炉本体烟道的中部布置，而两组悬吊机构对称地设置在振打除灰装置的两侧；每组悬吊机构中，包括若干个与传热面管一一对应设置的悬吊机构。
作为本发明的进一步改进，本发明所述夹马装置包括两片夹马，分别为宽夹马、窄夹马；宽夹马、窄夹马的相对面上均对应设置有与传热面管竖直方向节距相同的半圆形凹面，以使宽夹马、窄夹马抱箍于传热面管的表面。
作为本发明的进一步改进，本发明所述振打除灰装置包括支架、转动轴、密封传动箱、内部振打杆以及外部振打杆，其中：内部振打杆固定安装在传热面管竖直方向的底部；密封传动箱焊固于锅炉本体的外侧壁上，且密封传动箱内设置有外部振打杆，该外部振打杆与大气接触侧设置有柔性密封组件；所述外部振打杆与所述内部振打杆在锅炉本体烟道内侧同轴地无间隙接触布置；所述转动轴与调频电机的动力输出端连接，且转动轴通过设置于锅炉本体烟道内的支架支撑，该转动轴上顺序设置有若干振打锤组件。
作为本发明的进一步改进，本发明所述的传热面管设置为水平往复曲折的蛇形结构。
作为本发明的进一步改进，本发明所述的传热面管为多组，各组传热面管相互平行。
作为本发明的进一步改进，本发明所述传热面管为顺列或者错列布置。
根据以上的技术方案，相对于现有技术，本发明具有以下的优点：
1.本发明改变了立式锅炉中传热面管的布置方式，由横排改变成竖排，并在传热面管底部配装振打清灰装置，使得振打清灰时，传热面管作为整体进行清灰操作，振动传递效果好，清灰效果明显；其上的积灰由上至下依次跌落，可以防止传热面管表面积灰，有效地避免产生由此造成的传热面管换热效率降低的现象。
2.结构简单紧凑，密封性能好，减少系统漏风量，大幅提高换热效率。
3.设备运行稳定可靠，减小系统维护工作量，降低设备运维成本。
4.可调频次(变频)的机械方法振打，有效降低了所述余热锅炉自耗能，进一步提高余热锅炉系统的经济效益。

所述的振打方法是通过所述振打除灰装置7的若干振打锤组件13顺序对所述外部振打杆17进行水平方向的振动冲击，通过外部振打杆17传导予焊固于传热面管3上的内部振打杆11，进而使传热面管3以一定频率振动。水泥窑窑尾及旁路放风余热锅炉采用立式框架结构，传热面管3竖直悬吊在锅炉钢架2的通风梁6底面，余热锅炉的烟气入口到烟气出口依次为蒸汽过热器，蒸发器及软水加热器。
本发明的传热面管3采用蛇形光管或膜式管，传热面管3与传热面管3之间采用顺列或错列布置，通过竖直方向的双轴悬吊结构设置，传热面管3沿通风梁6通风冷却的水平方向可自由晃动，有效提高振打除灰装置7的清灰效果，大大提高锅炉本体的热效率。
本发明方案所公开的技术手段不仅限于上述技术手段所公开的技术手段，还包括由以上技术特征任意组合所组成的技术方案。
以上述依据本发明的理想实施例为启示，通过上述的说明内容，相关工作人员完全可以在不偏离本项发明技术思想的范围内，进行多样的变更以及修改。本项发明的技术性范围并不局限于说明书上的内容，必须要根据权利要求范围来确定其技术性范围。
