Abstract

本发明是一种锅炉钢珠除灰装置。现有的锅炉钢珠除灰装置中存在着一个较普遍的缺点，就是设在烟道外或烟道内露点以下温度处的储珠斗中，钢珠遇水易锈结成块，即便是只锈成核桃大小的结块，也足以堵塞喷嘴或其它出口，造成除灰中断。而且据调查分析，钢珠中的水一般不易消除。本发明的特征是：在锅炉温度达露点以上700℃以下的空间位置处，设置了一套钢珠不易生锈的储珠设备，同时为实现钢珠除灰的自动化创造了条件。

Description

本发明属于锅炉钢珠除灰装置。
目前在工业锅炉行业中广泛使用的钢珠除灰技术，最早见于美国专利，如US-2665118、US-329197。其较蒸汽吹灰和空气吹灰技术具有较大的优越性，特别是对烧油锅炉中形成的粘性积灰和牢固性积灰，使用钢珠除灰往往能取得较好的效果。现行钢珠除灰装置多是使用空气（或蒸气）通过喷嘴输送钢珠的，但是这种钢珠除灰技术中存在着一个较普遍的缺点。就是钢珠遇水锈结成块的问题，钢珠锈结成块以后，往往需要操作人员将储珠设备拆开，钎凿锤打方能松开，即便是只锈成核桃大小的结块，也足以堵塞喷嘴或其它出口，造成除灰中断。如1976年水利电力出版社出版的《燃油锅炉燃烧设备及运行》一书介绍的使用压缩空气或蒸汽通过喷嘴输送钢珠的钢珠除灰装置，就是将储珠斗设置在锅炉烟道以外的，这种储珠方法钢珠极易锈结成块，又如;在日本专利JP-58-217112（A）中，公开了一种水泥厂废热锅炉灰除设备和方法，这种方法是用颗粒状物料代替钢珠对热交换器表面进行除灰的，这些颗粒状物料随同清除下来的灰垢一起做为制造水泥的原料。显然，在这种除灰方法中，如果采用钢珠代替颗粒状物料，钢珠仍会锈结成块。
据调查，现行钢珠除灰设备中，水的来源主要是烟气凝结、附着在钢珠表面的SO3从空气中吸水、省煤器泄漏水等，一般不易消除。
本发明的目的是：设计一种利用锅炉本身温度在露点以上的余热去干燥钢珠的储珠斗，以解决钢珠锈结问题。同时力求使钢珠在储珠斗内始终处于松散状态，为减少操作人员的体力劳动，实现钢珠除灰的自动化创造条件。
本发明的技术解决方案是：一种锅炉钢珠除灰装置，它包括储存钢珠的储珠斗，控制储珠斗内钢珠下落的落珠门;散布下落钢珠的散布器;收集下落的钢珠和除下的烟灰的灰斗;分离来自灰斗的钢珠和烟灰的灰珠分离器;用空气（或蒸汽）来赋于钢珠动能的喷嘴;输送钢珠的升珠管及用于分离来自升珠管的钢珠与空气（或蒸汽）的气珠分离器;其特征在于：本发明的储珠斗安装在锅炉烟道内锅炉烟气露点以上，700℃以下温度的空间位置处。
本发明的储珠斗是底部为锥度110°-118°的圆锥斗。
本发明的装在储珠斗下的支承架，一端固定，另一端装有热膨胀补偿器和固定用的弹簧减震器。
因为本发明将储珠设备装在了锅炉烟道或通有锅炉烟气的保温容器内，所以本发明和已知的锅炉钢珠除灰装置相比具有如下优点：
本发明采用喷嘴输送钢珠，比美国专利US-2665118、US-329197中公开的采用机械传动的方法减少设备，而且节约能源;本发明与《燃油锅炉燃烧设备及运行》一书介绍的在炉外储存钢珠的方法相比，具有钢珠不会锈结成块，易于自动控制的优点;本发明与日本专利JP-58-217112（A）相比，具有钢珠不会锈结成块，因而不必采用颗粒状物料代替钢珠的优点，因为在JP-58-217112（A）中所公开的废热锅炉除灰装置中，如采用钢珠代替颗粒状物料，则钢珠会锈结成块。本发明还有其它积极效果：首先，它用较少的投资就可以彻底解决钢珠遇水生锈结块的问题，使钢珠除灰装置正常运转。其次，由于钢珠在运行的锅炉中始终处在一定炉温的干燥状态下，排列松散，无任何粘连、锈结现象，这样在除灰时就不象以往的钢珠除灰装置那样需操作人员经常打开储珠 设备进行观查或消除锈块，所以它便于实现钢珠除灰的自动化控制，再次，它可以延长两次除灰的时间间隔和采用不定期除灰。现行的锅炉钢珠除灰装置，需要每天都进行除灰，若不这样储珠斗内的钢珠很可能结成一个很大的锈块。另外，据有关资料反应，不论正负压除灰，每次除灰只可使锅炉排烟温度下降1-2℃，却需要消耗较多的除灰动力能源，再有，每天除灰，受热面在钢珠长期、频繁的冲刷下磨损也较大，本发明可以选择一个最佳除灰时间间隔，使除灰按最经济的时间、次数运行。这样即可以减少除灰次数，节约除灰的动力能源，减少受热面的局部磨损，又可以保证除灰，降低锅炉的排烟温度。
附图说明：下列附图描述了本发明的几个实施例。图1中所标示的明细号码为本说明书和权利要求书统一使用的号码。
图2为本发明的钢珠除灰装置在烟道顶部位置;
图3为本发明的钢珠除灰装置在烟道中部位置;
图4为本发明的钢珠除灰装置在烟道下部位置;
图5为本发明的钢珠除灰装置在烟道顶部与气珠分离器加装在一起的位置。
实施例：图1是一套装在锅炉尾部省煤器烟道顶端的储珠设备。储珠斗（8）是一个锥底为117℃的圆锥斗。用两根钢梁制成支承架（9），支承架（9）一端焊在烟道壁上，一端装有滑动式热补偿器（11）和蝶形弹簧减震器（12）。储珠斗放在两根钢梁支架之间的中间位置处。在储珠斗的上方，落珠管的末端装有一个密封阀（7），用它防止带水空气的进入。储珠斗的下方装有一个落珠门（10）。密封阀（7）和落珠门（10）均采用滚筒式开关阀，以防止发生卡珠现象，其开关柄用万向节头连接操纵杆于烟道之外。该点的炉温为370℃左右，因此储珠斗（8）、密封阀（7）、支承架（9）、落珠门（10）均用普通碳钢制造。
下面参照附图1的实施例说明本发明的操作过程：这里所讲的操作过程是钢珠从停车状态（此时落珠门（10）是关闭的，储珠斗（8）内储满钢珠，密封阀（7）是关闭的），操作到工作状态后，再恢复到停车状态。
开启吹动钢珠工作的压缩空气或蒸汽阀门向钢珠吹灰系统中引入压缩空气或蒸汽，通过连接在炉外的操作杆开启落珠门（10）和密封阀（7），此时钢珠除灰装置进入工作状态：钢珠自然落下，经散布器（13）后，均匀地分布在锅炉尾部受热面上，将受热面上的积灰清除，除灰后钢珠落入灰斗（1）。灰斗底部的灰珠分离器（2）将灰与钢珠分离，分离后的烟灰随锅炉烟气进入烟囱，钢珠则由灰珠分离器（2）漏出落进收集器（3）然后进入喷嘴（4），压缩空气或蒸汽将钢珠沿升珠管（5）输送到气珠分离器（6）内，气珠分离器（6）将钢珠与压缩空气或蒸汽分离，分离后的压缩空气或蒸汽排入大气，钢珠沿落珠管经密封阀（7）落入储珠斗（8）中，循环往复除灰，受热面的积灰清除干净后，首先关闭落珠门（10），待钢珠除灰系统中的钢珠全部输送到储珠斗（8）中以后，关闭密封阀（7），然后关闭压缩空气或蒸汽阀门，除灰结束，钢珠除灰装置进入停车状态。钢珠数量减少后，通过收集器（3）装添钢珠。
本发明中在锅炉温度达露点以上，700℃以下的空间位置处加装的储珠斗设备，是既可以装在锅炉炉室内露点以上，700℃以下的空间位置处，也可以装在锅炉炉室外通有露点以上烟气，并加有保温容器的空间位置处，其装在锅炉炉室内的空间位置处，主要是指工业锅炉尾部省煤器烟道内的不同位置处。具体位置可以装在烟道的顶部，也可以装在烟道的中部，还可以装在烟道的下部。储珠斗设备装在锅炉炉室外通有露点以上烟气，并加有保温容器的空间位置处，其随意性较大，可以在原有的收集器（13）上外加一个保温容器，也可以装在烟道的顶部气珠分离器下边（如图5所示），不论装在什么地方均可以方便使用，减少原材料为原则。
本发明中的储珠斗底部之所以设计成锥度为110°-118°的圆锥斗，是为了自然顺利落珠，防止钢珠受热膨胀后产生“穹窿”现象。该角度是实际测定出来的。
本发明的装在储珠斗下的支承架（9），一端固定，另一端装有热膨胀补偿器（11）和固定用的弹簧减震器（12）。这是因为钢结构的支承架受热后膨胀较大，若不加热膨胀补偿器，很可能会出现支承架弯曲现象，造成储珠斗位移，加装弹簧减 震器是为了减少储珠斗随运行中的锅炉一起震动。
本发明中的装在储珠斗上的密封阀（7）和储珠斗下的落珠门（10），随储珠斗一起装入烟道内或保温容器内。这是为了保证储珠斗具有隔水功能，不发生结露现象，由于密封阀和落珠门装入烟道或保温容器内，受热膨胀后很可能产生位移，使开关柄与操纵杆不同心，卡住开关柄，因此用万向节头将开关柄与操纵杆连接于烟道或保温容器之外。
本发明的储珠斗（8）、密封阀（7）、支承架（9）和落珠门（10）均用金属制造。选用什么材质主要应视储珠设备所处位置的炉温而定。一般情况下选用普通碳素钢即可，特殊情况下也可选用高温钢和不锈钢。
