Description

一种防腐收尘烟囱 技术领域
本发明涉及烟囱， 进一步是指具有无腐、 收尘、 节能功能的烟囱。 背景技术
近年来， 为保护环境， 将冶炼、 发电、 化工等行业产生的含有害物二氧 化硫的烟气在其进入烟 @前即进行湿法脱硫， 从而使烟温下降至露点以下； 但由此产生的酸液沿烟 @内壁下流， 极易使内衬腐烂导致筒体开裂。
为解决这一问题， 一般的方法是在烟囱内装设内衬， 内衬造价昂贵。 例 如一个 60万千瓦火电厂的 210米烟囱， 内衬投资竟需 1000万元， 且此法也 只不过是一个便于更换的措施而已， 是治表不治本的办法。
还有一种解决方式， 如中国专利 CN85108753 公开了一种烟道呈切线方 式与烟囱筒体连接的烟 ，中国专利 CN200920066079公开了一种烟道呈弧线 方式与烟囱筒体连接的节能烟囱， 在很大程度上具有无腐、 收尘、 节能的功 能， 然而， 部分烟囱由于位置局限， 其烟道无法采用切线方式或弧线方式与 烟囱筒体相连， 因此， 有必要对烟道与烟囱筒体的连接方式进行适应性地改 良。
另外， 现有的烟囱， 特别是无腐收尘节能烟囱， 其烟道由烟囱的管心线 接入烟囱或是弧线平滑接入 （如切线进入烟囱）， 其进到烟囱本体的入口 （即 进烟口） 均为矩形。 这种矩形入口的结构形式对烟囱结构强度不利， 且设计 要求高， 投资大。 发明内容 为了克服现有的部分烟囱的进烟道无法采用切线或弧线方式与烟囱筒体 相连的不足， 本发明旨在提供一种无腐收尘节能烟囱， 该烟囱的烟道采用非 切线的直线或非弧线的曲线方式与烟囱筒体相连， 其烟气流通顺畅， 且造价 相对低廉， 具有无腐、 收尘、 节能的功能。
为了实现上述目的， 本发明所采用的技术方案是： 所述无腐收尘节能烟 囱包括烟囱筒体和设在所述烟囱筒体下部的进烟口， 其结构特点是， 进烟道 为位于烟 @筒体下端外侧的非弧形的曲线烟道或位于烟 @筒体下端外侧且与 该烟囱筒体非切线连接的直线烟道， 该曲线烟道或直线烟道的出口与所述烟 囱筒体内壁平滑连接， 所述曲线烟道或直线烟道的进烟方向与邻接的烟囱筒 体内壁螺旋线弧旋方向为同向。
为了改善烟囱筒体进烟道的结构形式， 增强烟囱结构强度， 设在所述烟 囱筒体下部的进烟口的的径向截面形状为圆形或椭圆形。 所述进烟口的的径 向截面形状也可以为多边形或带倒圆角的多边形。 尤其是所述进烟口的的径 向截面形状可以为矩形， 包括正方形。
为了进一步地提高烟气流的流通效果， 所述进烟口的一侧设有置于烟囱 筒体内的导流板， 该导流板与烟囱筒体相连接的一端与该导流板另一端所构 成的平面 b相对于出口导流板处烟囱筒体切线的夹角 a为 20° ~90° 。更进一 步地， 所述导流板优选为直板或曲线板， 更优选为弧形板， 当导流板为弧形 板时， 该弧形导流板的为弧背 （凸面） 朝向烟囱轴心方向， 便于对烟尘进行 贴壁导流。
所述进烟口优选为一个或两个， 其径向截面形状均为圆形或椭圆形。 当 一个烟 @设置两个进烟口时， 最好将该两个进烟口相互平行布置， 以使进入 的烟尘可以以相同的旋向在烟囱筒体中进行无腐收尘节能的目的； 也可由一 个进烟口单向进入的烟尘形成旋流， 同样达到无腐收尘节能的目的。 对于有 两个进烟口的现有烟囱， 还需要保证两进烟口的导流板相互平行布置， 便于 烟气在烟 @筒体内产生同旋向的旋流。
在所述进烟口的另一侧开有一个缺口。
进一步地， 上述烟囱筒体由下至上有不同的坡比。
藉由上述结构， 上述结构的烟囱， 突破传统设计， 将进烟烟道做成非弧 线的曲线烟道或非切线的直线烟道， 参见图 4， 它能使烟气在烟囱筒体内回旋 形成外旋流和内漩流； 烟气自曲线烟道或直线烟道通过进烟口进入烟囱筒体， 能在进入烟囱筒体前， 于曲线烟道或直线烟道中预先产生良好的旋转， 有助 于提高除尘效率， 使总压损失小、 烟气含尘量大为降低， 而且烟羽刚度大； 烟气进入烟囱后， 可继续维持螺旋上升。 由于烟气流螺旋上升离心作用， 烟 气流内尚存的少量尘埃颗粒主要分布在烟道中心。 烟气发生冷凝与所含尘粒 有关， 首先是依赖与尘粒形成冷凝核， 然后逐渐扩大形成全局冷凝。 由于尘 粒多集中在烟道中心， 故冷凝多发生在烟道中轴一带， 而近壁烟流仍能维持 未饱和状态， 壁面干燥， 不受冷凝液体腐蚀。
与现有烟囱相比， 本发明的有益效果是： 本发明为一种高效无腐收尘节 能烟囱， 其结构稳定度高， 环保效果好； 本发明烟囱与同高度、 同排放量常 规烟囱相比， 环保效果提高 25-45% , 自身阻力低 20% , 因而可降低引风机动 力消耗 8.5 %左右； 烟气在筒内回旋， 相当于旋风除尘器， 可收尘 30%-80%； 还使得烟 @内衬不腐蚀， 使用寿命大大延长， 且造价相对低廉。
通过把烟囱进烟口改为圆形或椭圆形， 使烟囱本体的结构简单、 稳定， 下面结合附图和实施例对本发明作进一步阐述。 附图说明
