Background
The blast furnace slag flushing water is a large amount of high-temperature slag generated after the blast furnace ironmaking process is cooled by a slag pool, and a large amount of high-temperature hot water at 70-90 ℃ can be generated in the cooling process. The blast furnace slag flushing water is used as a low-temperature waste heat source and has the characteristics of stable temperature and large flow. At present, the waste heat recovery and utilization mode of the blast furnace slag flushing water mainly comprises heating. The waste heat of the blast furnace slag flushing water is mainly used for heating in winter, but has some problems: 1) And (5) directly heating. Slag washing water contains a large amount of impurities, is easy to cause blockage, abrasion and corrosion when entering a pipe network, and has huge heat supply network system and very difficult cleaning. 2) And (5) indirectly heating. The heat exchanger is adopted for heat exchange heating, but the scheme needs to additionally purchase the heat exchanger of the slag flushing water, meanwhile, the slag flushing water is corrosive and can corrode heat exchange equipment, and particulates such as water slag can block equipment such as valves and the heat exchanger in the system, so that the service life of the heat exchange equipment is shortened. Wastewater treatment technologies are ubiquitous in steel enterprises, and environmental regulations becoming strict make wastewater zero discharge in the steel industry a necessary trend, and membrane technologies are widely applied to the wastewater zero discharge. The ultrafiltration, nanofiltration and reverse osmosis membranes have higher requirements on the temperature of water, and the water inlet temperature is generally controlled to be about 20 ℃. However, in winter, if no measures are taken, the temperature of the water entering the water tank cannot reach the temperature, so the water temperature is low, and 1) the water yield is reduced under the condition that other conditions are the same; 2) The flux of the membrane is affected, the permeation efficiency is further reduced, and the pollution and blockage are increased, so that the service life of the membrane is shortened.
