背景技术
目前有多种的卧式燃料裂解炉尾气的排放与处理系统，但这些系统在使用过程中在短期内就会出现管道及设备严重破损，及水温过高致使水泵报废等现象，其主要是源于没有考虑到热气流带动碳尘粒引发对管道及设备的破坏性冲击力的问题，同时在排放尾气的过程中还含有较大的黑烟与高温排放。如中国专利申请号为 CN02147836.8 授权公开文本中就提到了一种 再生橡胶生产工艺尾气净化方法，主要是从再生橡胶动态脱硫罐排出的含水汽、微量恶臭及有害的可燃气体通过管道送入一、二级热交换器降温、减压，后进入气体膨胀器、气体吸收塔，并以碱液吸收硫化氢，气体吸收塔出来的尾气通入循环吸收分离器，以碳酸钠溶液吸收硫化氢，并进行气液分离，循环吸收分离器排出的干燥废气通入焚烧炉，焚烧炉排出的尾气经冲激式水浴除硫除尘器吸收二氧化硫，之后尾气经烟囱排入大气。此发明的再生橡胶生产工艺尾气净化方法能大量节约能源，减少燃煤消耗，环保效果好，减少环境污染，同时改善操作工人的劳动环境，避免有害气体对人们的伤害。虽然可以减少尾气中含有污染大气的成份，但并不能有效除去尾气中含有的碳尘粒及降低整个尾气的高温。

另外，还包括有烟气排放系统，所述的烟气排放系统包括有三部分，下部是圆桶型罐体 9 ，罐体项部通过管道连接中部的热交换器 8 ，上部的气体排放管道 16 与热交换器相通连接，热交换器主要是将由下部上升而来的热水蒸汽起到气相分离的作用，随便气体继续向上通过上部的气体排放管道。其中，所述的下部罐体 9 与混合管道 54 的出口相连接，下部罐体 9 上设置有湿性碳尘渣口 90 及出水口 92 ，所述的气体排放管道 16 内也设置有可喷碱水的环型喷雾咀 162 ，喷雾咀中设置有碱性喷雾用水，同样是石灰水或者已稀释的氢氧化钠水；经前面多道装置的处理，在此处尾气中尚残余有二氧化碳存在，因此，在该环形喷雾喷咀以喷雾方式向下喷淋碱性水时与二氧化碳再次接触生成碳酸盐类物质。
另外还设置有可使热交换器 8 中的循环水、气固分离器 2 中的循环水及碳渣过滤器 4 中的循环水循环的循环水冷却系统；该循环水冷却系统包括有冷却塔 7 、下部罐体 9 上的出水口 92 为热水出口，热水出口直接水渣池 17 ，同时与水渣池 17 连接设置有过滤式沉渣池 12 ，碳渣过滤器 4 的排液固管 40 排出的液渣通往过滤式沉渣池 12 ，过滤式沉渣池 12 中的水通过循环冷却水泵 11 进出冷却塔 7 ；另外与所述冷却塔 7 连接有热循环水泵 13 ，该水泵 13 同时与热交换器 8 、气固分离器 2 及碳渣过滤器 4 的热交换器水管 15 及前级循环水管 14 相连接。其中所述的气体排放管道 16 及热交换器 8 上设置有相通的后级循环碱性冷水管 10 ，该后级循环碱性冷水管 10 与循环水冷却系统相接，循环水冷却系统还外接有冷水补给管 19 ，从而从系统出水口 92 流出的热水（ 40 － 6 0 ℃ ）进入水槽，再经过冷却塔的冷却进行水过滤系统处理后循环处理，如水温超过设定温度时，再由另外的冷水设备制冷补给。
