Description

一种用于燃烧炉回喷系统的沥滤液预处理系统 技术领域
本发明涉及一种污水处理装置，更具体地说，涉及一种用于燃烧炉回喷系统的沥滤液预处理系统。
背景技术
随着垃圾焚烧技术在中国的逐步推广，为防止焚烧过程中产生的'二次污染'，垃圾沥滤液必须经过处理达标后才能排放，因此沥滤液的处理技术受到国内外环保界的广泛关注。
在目前没有经济可靠工艺的情况下，部分已投运的垃圾焚烧厂将沥滤液运往城市污水处理厂与生活污水混合处理；还有部分厂家采用高运行费用的工艺。
纵观国内外沥滤液处理现状，主要工艺有回喷法、生化法、 MBR 法等以及上述方法的综合运用。其中回喷法相对其他方法工艺简单、成本低，为西方发达国家广泛采用。但是回喷法适合于沥滤液产量少、垃圾热值高的场合。对于热值较低的垃圾则不适合，否则会造成焚烧炉炉膛温度过低、甚至熄火的状况。
西方发达国家由于垃圾中厨余物少，热值高，沥滤液产量少，一般采用将沥滤液回喷焚烧炉进行高温氧化处理。由于沥滤液较少，平时将沥滤液集中在池内，当垃圾热值较高时，用高压泵将沥滤液加压经自动过滤器、回喷系统喷入焚烧炉进行处理，当垃圾热值较低时停止。
中国城市生活垃圾的厨余物多、含水率高、热值较低，焚烧法处理垃圾时必须将新鲜垃圾在垃圾储坑中储存 3~5 天进行发酵熟化，以达到沥出水份、提高热值的目的，才能保证后续焚烧炉的正常运行，因此其沥滤液污染物浓度高、水质变化大、带有强烈恶臭，呈黄褐色或灰褐色。
现有技术中垃圾沥滤液通过简单过滤后直接喷入炉膛内的沥滤液预处理方式主要针对的是国外垃圾沥滤液量少，杂质少的工况设计。但中国垃圾的含水率太高，沥滤液产量大，现有技术的沥滤液预处理方式对国内垃圾沥滤液量大，杂质多的工况不能适应。导致整套系统维护工作量很大，系统可靠性很低。
发明内容

在本发明所述用于燃烧炉回喷系统的沥滤液预处理系统中所述一次连接管道的进液口设置在所述一次过滤装置中，并位于所述沥滤液池的沥滤液面以下。

在本发明所述用于燃烧炉回喷系统的沥滤液预处理系统中所述一次过滤装置包括拼接成框体的过滤网。
在本发明所述用于燃烧炉回喷系统的沥滤液预处理系统中所述一次过滤装置的顶面开放并位于所述沥滤液池的液面上，一侧通过连接件固定安装在所述沥滤液池的侧壁上。
在本发明所述用于燃烧炉回喷系统的沥滤液预处理系统中所述二次过滤装置的海拔高度大于所述中间储存罐的海拔高度；所述中间储存罐的海拔高度大于所述沥滤液池的海拔高度。
在本发明所述用于燃烧炉回喷系统的沥滤液预处理系统中所述中间储存罐底部设有排污管道，所述中间储存罐的排污管道的出口连接至所述沥滤液池。
在本发明所述用于燃烧炉回喷系统的沥滤液预处理系统中所述中间储存罐的上部设有溢流管，所述溢流管的出口连接至所述沥滤液池。
