Description

一种垃圾与半干污泥协同焚烧处理方法与装置 技术领域
本发明涉及垃圾焚烧，尤其涉及一种垃圾与半干污泥协同焚烧处理方法与装置。
背景技术
近年来我国城市化进程发展迅速。按现在的增长速度预测，2010年我国城市生活垃圾将达到2.64亿吨，2030年为4.09亿吨，2050年为5.28亿吨。我国城市生活垃圾产量同步快速增长。全国城市人均生活垃圾产量440公斤，每年总量1.6亿多吨，占世界总量的1/4以上，且以每年8％-10％的速度增长，环境污染日益严重。城市生活垃圾常规处理方法有填埋、堆肥和焚烧发电。填埋法由于成本低，技术成熟，管理方便等优点而在垃圾处理中得到了广泛的应用。但填埋的垃圾并没有进行无害化处理，残留着大量的细菌病毒，垃圾的渗漏液会污染破坏土壤和地下水资源，直接威胁到环境安全和公众健康。其中垃圾焚烧发电因处理较彻底、减容量大、处理时间短、占地面积小、回收热能等优点，而倍受关注，得到较快的发展。截止2016年2月，全国在运行的垃圾焚烧厂已达231座。
另一方面随着我国城镇化和工业化进程的加快，污泥产量大幅增加，而处理不当会导致严重的环境污染问题。焚烧污泥可将污泥中的水分和有机质全部去除，杀灭一切病原体，并能最大限度地降低污泥体积，减少污染物排放，成为了处理处置污泥的有效手段。近年来生活垃圾产量与热值快速增加，焚烧垃圾可以为污泥的焚烧提供足够的热量。根据相关规定已有或规划建有 生活垃圾焚烧发电厂的城市，宜优先选择采用污泥与生活垃圾混合焚烧方式处理处置污泥，既可以利用垃圾焚烧厂的焚烧和尾气处理设备，又可以节省投资和运行成本。污泥与生活垃圾混合焚烧发电实现了污泥处理“减量化、稳定化、无害化”的目的，具有良好的经济效益。

所述余热锅炉8连接汽轮发电机11；余热锅炉8内的水加热后产生蒸汽，并推动汽轮发电机11发电；
所述湿污泥配送单元包括污泥仓10、螺旋运输机9；螺旋运输机9将污泥仓10内的湿污泥运送至炉膛后拱，湿污泥在重力作用下散落至炉膛内的炉排6上。
在炉膛入口处设置有将外部空气吹入炉膛内的二次风机5，促进炉膛内气体未燃尽物二次燃烧，在二次风机5的回吹扰流作用下，烟气相互卷吸，以此延长850～900℃的烟气在炉膛出口区域停留时间；
所述炉排6自上而下依次分为干燥段A、热解段B、固定碳燃烧段C、固 定碳燃尽段D。
所述脱酸反应塔12还连接有一石灰供给仓14；所述脱酸反应塔12与布袋除尘器16之间的管路上还连接有一活性炭供给仓15。
所述垃圾配送单元包括垃圾仓2、抓吊装置3；抓吊装置3用于将垃圾仓2内的垃圾抓吊至进料斗，垃圾由进料斗进入炉膛内的炉排6上；
所述余热锅炉8、脱酸反应塔12、布袋除尘器16的下部的飞灰由灰仓13统一收集。
所述炉排6的底部设有送风机7，用于给炉膛内送风，使膛炉内垃圾充分燃烧；所述垃圾仓2的底部还设有用于收集垃圾中液体的渗滤液收集池1；炉排6的下方设有炉渣池4。

接着，从余热锅炉8排出的烟气进入脱酸反应塔12，与来自石灰供给仓14的消石灰微粒接触发生中和反应后，再经过来自活性炭供给仓15的活性炭吸附烟气中夹带的颗粒物后，烟气经过布袋除尘器16，烟气中的颗粒物和反应物最终在布袋除尘器16中被捕集，烟气经引风机17进入烟囱中排入大气中。

(3)焚烧产生的炉渣，可被二次利用，用作建筑原材料，如水泥、砖和混凝土等建筑材料，保护环境，实现污泥处置的资源化利用；
综合以上，本发明技术手段简便易行、环保效果好、经济效益高的优点，可广泛地适用于工业和城市生活垃圾与污泥焚烧，应用前景较广。

    在炉膛内的垃圾及湿污泥经过一次风和炉膛辐射的作用下，在炉排上完成干燥、热解、固定碳燃烧和固定碳燃尽这四个燃烧过程，焚烧产生的高温烟气进入余热锅炉(8)内，对余热锅炉(8)的水加温并形成蒸汽，蒸汽推动汽轮发电机(11)；
    接着，从余热锅炉(8)排出的烟气进入脱酸反应塔(12)，与来自石灰供给仓(14)的消石灰微粒接触发生中和反应后，再经过来自活性炭供给仓(15)的活性炭吸附烟气中夹带的颗粒物后，烟气经过布袋除尘器(16)，烟气中的颗粒物和反应物最终在布袋除尘器(16)中被捕集，烟气经引风机(17)进入烟囱中排入大气中。
