[0027] In order to further understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0028] A method for treating blast furnace slag that can directly obtain high-temperature dry slag provided by the present invention is as follows: liquid blast furnace slag flows into the upper water slag tank 1, and the liquid blast furnace slag is washed and cooled by water sprayed from high-pressure water nozzles. Due to thermal stress, the slag is The slag-water mixture 3 is broken into small particles of about 4 mm, and the slag-water mixture 3 flows down along the upper slag tank 1 by gravity; during the flow, the granulated blast furnace slag in the slag-water mixture 3 exchanges heat with water, After the temperature drops to 400-800°C, it falls on the special mesh conveyor belt 4, and the end of the upper water slag tank 1 is equipped with a terminal slag retaining net 6 to ensure that the...
