实施方式 1 :
如图 1所示本发明第一实施方式的复合燃烧锅炉, 包括锅炉 31, 复合炉膛 24, 将燃料经添料装置 28送入锅炉燃烧室 29中的炉排 30上进行燃烧, 再经箱 式集热器 27生产热水或蒸汽, 燃烧后的炉渣经炉排 30排出锅炉 31外进入复合 炉膛 24的旋转炉条 40上进行燃烧, 再经箱式集热器 26生产热水或蒸汽, 锅炉 31中燃料燃烧时排出的烟尘经回烟风机 23, 回烟口 42导入复合炉膛 24的回烟 室 41中, 与风机经进气口 43压入的空气混合, 并穿过旋转炉条 40在有较高炉 温的炉渣中进行二次燃烧, 二次燃烧后的废气经脱硫除尘后排放大气中, 炉渣经 复合炉膛 24的粗排渣口 34排出至排渣装置 21上排出。
根据上述结构烟尘经循环流程,燃料和一次燃烧后的烟尘废气在复合炉膛 24 的高温炉渣中进行二次燃烧, 两次燃烧后排出的废气中没有可燃气体和颗粒, 另 外由于立体复合炉膛燃料较厚且呈焦炭状故炉温很高,远超过二恶英分解所需的 温度, 因而消除了环境污染, 节约了能源, 还降低了温室气体的排放。
实施方式 2:
如图 1所示本发明第一实施方式的复合燃烧锅炉, 包括锅炉 31, 复合炉膛 24, 将燃料经添料装置 28送入锅炉燃烧室 29中的炉排 30上进行燃烧, 再经管 式集热器 33生产热水或蒸汽, 燃烧后的炉渣经炉排 30排出锅炉 31外进入复合 炉膛 24的旋转炉条 40上进行燃烧, 再经管式集热器 32生产热水或蒸汽, 锅炉 31中燃料燃烧时排出的烟尘经回烟风机 23, 回烟口 42导入复合炉膛 24的回烟 室 41中, 与风机经迸气口 43压入的空气混合, 并穿过旋转炉条 40在有较高炉 温的炉渣中进行二次燃烧, 二次燃烧后的废气经脱硫除尘后排放大气中, 炉渣经 复合炉膛 24的粗排渣口 34排出至排渣装置 21上排出。
根据上述结构烟尘经循环流程,燃料和一次燃烧后的烟尘废气在复合炉膛 24 的高温炉渣中进行二次燃烧, 两次燃烧后排出的废气中没有可燃气体和颗粒, 另 外由于立体复合炉膛燃料较厚且呈焦炭状故炉温很高,远超过二恶英分解所需的 温度, 因而消除了环境污染, 节约了能源, 还降低了温室气体的排放。
实施方式 3:
如图 3所示本发明第三实施方式的复合燃烧锅炉,包括复合炉膛 24,传动电 机 35, 传动装置 36, 粗排渣口 34, 排渣装置 21, 炉渣在复合炉膛 24中进一步 燃烧后经传动电机 35带动传动装置 36旋转,从而带动旋转炉条旋转将炉渣排出 复合炉膛 24外, 其中颗粒较小的炉渣直接从旋转炉条间空隙落下, 较大块的炉 渣经旋转炉条转动至粗排渣口 34处排至排渣装置 21上排出。
根据上述结构由于旋转炉条间空隙有限因此大块的炉渣不可能从旋转炉条 的空隙间落下,通过开设粗排渣口 34可防止大块炉渣在复合炉膛 24内形成堵塞。 实施方式 4:
如图 4-5所示, 本发明的第四实施方式的定向助燃风冷式旋转炉条包括 旋转炉条壳 19、 电机 12、 风机 13、 传动装置 11风机泵 14, 在炉膛 1的下 方是旋转炉条壳 19, 旋转炉条壳 19上有组装式排渣板或排渣齿 5, 设置在旋 转炉条壳 19的齿座 39上, 旋转炉条壳 19上有孔与炉条风室 6相通, 旋转 炉条壳 19的轴端经传动装置 11与电机 12联接,若干个旋转炉条壳 19间经 联动装置连接, 轴端与壳体经轴套或轴承 9联接, 内侧有一带密封盖 10的 小风室并有管道与炉膛 1的风室 2相通, 旋转炉条壳 19的另一端内径两端 与中轴 18通过两轴套或轴承 7和 17联接, 外段有密封盖 16、 中轴 18在外 侧有孔经管道 15 , 与炉膛风室 2相通, 外端与电机 13、 风机 14联接, 中轴 18在旋转炉条壳 19的内部或外侧有与中轴固定在一起的定向凹板 8, 幵口 朝向炉膛 1, 炉膛内侧有耐火材料 20, 炉膛 1外壳一侧有透明观察窗 3, 内 置隔尘网 4, 炉膛底部有回烟室 22, 回烟室 22上有回烟孔 23, 炉膛 1的至 少一侧有粗排渣孔 21。
根据上述结构, 由于定向凹板 8的开口始终朝向炉膛方向,故对炉膛中 的燃料燃烧起助燃作用, 同时对旋转炉条壳 19起到降温的作用延长了使用 寿命, 防止了炉条壳的变形, 电机 12旋转经传动装置 11 带动旋转炉条壳 19旋转, 旋转炉条壳 19与中轴 18间有轴套或轴承 7和 17故中轴 18和定 向凹板 8可以固定不转, 在风机 13、 泵 14的作用下使炉膛 1的炉膛风室 2 和旋转炉条壳 19的炉条风室 6中充满有一定压力的空气并经孔或槽吹向炉 膛 1中, 增强了燃烧效果,通过在旋转炉条壳 19上设置组装式排渣板或排渣 齿 5可有效地提高旋转炉条壳 19的使用寿命, 降低成本减少维修费用, 旋 转落灰提高效率, 并使锅炉立体燃烧成为可行,立体燃烧的炉膛 1中炉温较 高可有效分解不易燃烧的有毒气体如二恶英从而使垃圾焚烧发电以无污染 排放得以实现。
以上虽然以一个锅炉 31与一个复合炉膛 24的组合为例进行了说明,但是本 发明也可具有多个锅炉或多个复合炉膛分别配置, 旋转炉条又分 1旋转炉条上 设置有组装式排渣板或排渣齿,若干个旋转炉条间有传动装置连接并有电机带动 旋转; 2旋转炉条上设置有组装式排渣板或排渣齿, 旋转炉条为中空有风机与之 相通, 旋转炉条上有孔与外部相通, 至少有一个旋转炉条的外端连接有风机, 若 干个旋转炉条间有传动装置连接并有电机带动旋转; 3旋转炉条上设置有组装式 排渣板或排渣齿,旋转炉条为中空有风机与之相通,旋转炉条上有孔与外部相通, 旋转炉条的内侧设置有定向凹板, 定向凹板开口始终朝向炉膛, 至少有一个旋转 炉条的外端连接有风机,若干个旋转炉条间有传动装置连接并有电机带动旋转的 多种不同的旋转炉条配置在复合炉膛中的方式进行设置。
以上所述的优选实施方式是说明性的而不是限制性的,在不脱离本发明的主 旨和基本特征的情况下, 本发明还可以以其他方式进行实施和具体化, 本发明的 范围由权利要求进行限定,在权利要求限定范围内的所以不同结构都落入本发明 的范围内。
