Research and Application of Ash Water Treatment Technology in Three High Coal Powder Coal Pressure Gasification Process
The ash water produced by the coal pressurized gasification unit of Jinergy Holdings Equipment Manufacturing Group Huayu Energy Chemical Shanxi Co.,Ltd.contains high suspended solids,colloids,solid particles,hardness,COD,ammonia nitrogen and other substances,and the temperature is relatively high,generally around 85℃.The recycling of grey water concentrates pollutants,leading to scaling and blockage of pipelines in the gasification furnace grey water system,which seriously affects the long-term stable operation of the system.After adding a hardness removal system to the grey water system,the problem of pipeline scaling caused by suspended solids,colloids,solid particles,and high hardness in the grey water has been effectively solved,achieving safe,stable,and long-term operation of the system.
