目前,冷却炽热焦炭的方法有两种:(1)湿熄焦工艺:用水直接冷却炽热焦炭,焦炭温度从大约1,000℃冷至100℃以下,产生的水蒸气含有污染物,除去大部分砂尘后排入大气;(2)干熄焦工艺:惰性气体(氮气、烟道气、或空气燃烧焦炭所产生废气)通过炽热焦炭,将热焦冷却;被加热的惰性气体用于加热锅炉产生蒸气等。一、干熄焦工艺发展概况干熄焦工艺在国外已有60年的发展历史。首先开始工业性干熄焦试验的是瑞士。 1.瑞士的沙耳法第一个干熄焦设计发表于1917年,称为沙耳法(Sulzer)。第二次世界大战以来共有54
At present, there are two ways to cool red hot coke: (1) The wet quenching process: direct cooling of hot coke with water. Coke temperature is cooled from about 1,000 ℃ to below 100 ℃. The generated steam contains pollutants to remove most of sand and dust (2) CDQ process: inert gas (nitrogen, flue gas, or air-generated coke combustion gas) through the hot coke, the hot coke cooling; heated inert gas used to heat the boiler to generate steam Wait. First, the development of CDQ technology CDQ process in foreign countries have 60 years of development history. The first to start an industrial CDQ test is Switzerland. 1. The first CDQ design from the Czar of Switzerland was published in 1917 as Sulzer. A total of 54 since the Second World War
