Problems solved by technology

[0002] Blast furnace ironmaking in the metallurgical industry produces a large amount of high-temperature liquid slag. At present, the water quenching method is mainly used to deal with the slag. etc., this method needs to consume a lot of water during the treatment process, and a large amount of H will be produced during the treatment process 2 S and SO x and other harmful gases, serious environmental pollution
The dry granulation that has appeared so far is more representative of the wind quenching method and the centrifugal method. The wind quenching method uses a high-power granulation fan to generate high-speed airflow to blow off and granulate the liquid blast furnace slag, which consumes a lot of power and has huge and complicated equipment. , large area, high investment and operating costs, when the flow of liquid blast furnace slag changes, the wind speed and air volume are not easy to coordinate
The centrifugal method relies on the centrifugal force generated by the high-speed rotation of the turntable or cup to granulate the liquid blast furnace slag. The particle size distribution of the granulated slag is relatively uniform, but the reliability of the granulation device rotating at high speed at high temperature is poor, and the granulation effect It is sensitive to the temperature and flow changes of liquid blast furnace slag, and the effect of adjusting the speed alone is not ideal
[0003] Since the blast furnace slag is intermittently discharged at the same blast furnace slag outlet, that is, one slag outlet is discharged after about 2 hours for another slag discharge, and the existing granulation system takes a long time to clean, and it is difficult to achieve granulation Sustainability

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0029] In this embodiment, a high-temperature slag granulation system can receive high-temperature slag and perform granulation treatment on the slag, and the processed slag can be used for secondary use.

[0030] Such as figure 1 As shown, the granulation system includes a slag tank 1 , a first regulating brick 2 , a second regulating brick 3 , and a granulating device 4 .

[0031] The slag trough 1 includes a slag trough straight section 5 and a slag trough inclined section 6. The slag trough straight section 5 is vertically fixedly connected to the top of the slag trough inclined section 6. In order to slow down the impact velocity of incoming slag, a The horizontal straight section 7 of the slag...
