对已生产的焦炉,如何从操作、设备上降低焦炭的水分?要求水分控制在7%以下。

降低焦炭水分: 1、从配煤和焦炉加热制度控制焦炭气孔大小,气孔多少和大小会影响焦炭的吸水性。 2、从熄焦工艺严格控制熄焦水量、时间、熄焦车焦炭均匀性(结焦均匀、熄焦焦车来回移动、焦车控水),杜绝或减少二次大水管灭焦情况 3.晾焦台焦炭均匀卸焦,凉焦时间长点, 4、焦炭水分取样要有代表性,及时送样化验。

之前我们有过焦油质量很差,水分、密度、甲苯不溶物、灰分都超标。水分脱不出来,往焦油内加入破乳剂,进行打循环脱水。

低水分熄焦技术,可控到5%以下

4楼,低水分熄焦,是否存有红焦?

去除干熄焦,低水分熄焦肯定有红焦,能做到四五个水分,但对焦台破坏较大

低水熄焦这种技术其实最关键的不是红焦问题,在熄焦塔内飞溅才是最难处理的。

低水熄焦将水分控制在7%完全不是问题。如果控制在6~7%焦台上应该没有什么红焦,4~6%时个别区域会有一些。
