The invention discloses a
slag water
quenching method and device, aiming at solving the problem of bad safety of
slag water
quenching treatment method in the prior art. According to the method,
slag is distinguished and treated according to volume. The method comprises the following steps: putting slag to a
processing station by a slag tipping unit, and turning on a pelletizer; cooling and crushing the slag with a
stream of water by the pelletizer, and tipping the processed slag onto a grid
sieve; letting the slag with large
diameter enter in a slag collecting pit, crushing and recovering steel
scrap, and letting the rest slag enter the slag collecting
pool; letting the slag with small
diameter enter in the slag collecting
pool, and stirring and grabbing to a dripping slag bin. The device comprises the slag tipping unit, the pelletizer, the grid
sieve, the slag collecting pit, the slag collecting
pool, a turbid circulating
water circulation system, and the dripping slag bin. The method and device disclosed herein have high safety, satisfy the requirements of steel-making,
sintering and other processes for recycling slag with proper
granularity, and are suitable for the field of steel-making technology.
