Description

一种用于垃圾焚烧发电厂沥滤液回喷燃烧的双流体喷枪 技术领域
本发明涉及一种垃圾焚烧发电厂沥滤液回喷设备，尤其涉及一种用于垃圾焚烧发电厂沥滤液回喷燃烧的双流体喷枪。
背景技术
我国垃圾焚烧处理过程中，垃圾沥滤液产生量大、有机物及氨氮浓度高，采用生化处理难度大，是垃圾焚烧工程主要处理技术难题之一。目前垃圾沥滤液主要处理方法为生化处理、直接或混合其他介质喷入焚烧炉进行燃烧(即回喷处理)。其中，生化处理投资、运行成本高，且工艺后段含有高浓度盐分的浓缩液难以处理。而相比其它垃圾沥滤液处理工艺，回喷方式相对更为简单，投资成本低，便于操作，是相对更为经济、可靠、彻底的处理方法。
现有回喷处理技术中，采用压缩空气或其他均质流体对沥滤液进行雾化的双流体喷枪最为常用(一种垃圾焚烧炉渗滤液回喷脱硝装置CN201520775711.6；生活垃圾渗滤液浓缩回喷系统CN201420805092.6；一种雾化喷枪CN201410007791.0等)，上述喷枪是固定在墙壁上，将沥滤液喷射入炉膛焚烧处理。
垃圾焚烧发电厂沥滤液双流体喷枪常工作在垃圾沥滤液高盐、高有机质含量、且焚烧炉膛内高温、多尘环境下，在正常工况下，容易产生堵塞，特别是在焚烧炉因调整工作负荷停喷、少喷时，经常发生堵塞而出现故障。当出现故障时，由于喷枪是固定在墙壁上并处于炉膛内工作位，喷头及喷枪极易在炉膛高温环境下烧损，更换不便，使用寿命有限。
发明内容
为了解决以上问题，本发明提出一种用于垃圾焚烧发电厂沥滤液回喷燃烧的双流体喷枪，采用压缩空气作为动力源，使双流体喷枪在沥滤液喷头堵塞时，能够自动退出炉膛，保护喷枪及喷头不被烧损，提高喷枪的使用寿命，并且，双流体喷枪在自动进入或退出炉膛之后，能够自动打开或关闭双流体的管道阀门，进一步提高安全性和可靠性。
