The waste heat of blast furnace slag water was obtained by negative pressure flash technology,and the extracted negative pressure steam was used as the power source of lithium bromide refrigerator to produce cold water,cold water en-ters the front dehumidifier of blast furnace blower to achieve blast air dehumidification.The negative pressure steam technol-ogy of extracting residual heat from blast furnace slag water is combined with the blast furnace blast dehumidification tech-nology of lithium bromide refrigeration,which solves the problem of equipment clogging caused by solid impurities in the process of utilization of blast furnace slag water,and also puts forward higher requirements for the design,control and main-tenance of equipment and pipelines.
