The high-temperature molten slag waste heat high-efficiency recycling device comprises a stock bin, a soaking bin and supports, the bottom end of the stock bin is connected with a material guide port, the input end of the soaking bin is connected with the material guide port, the bottom end of the soaking bin is fixedly connected with the plurality of supports, a material disturbing rod is arranged inside the stock bin, a driving motor is installed on the upper surface of the stock bin, the output end of the driving motor is connected with a driving shaft, the material disturbing rod is connected with the driving shaft, a filter plate is arranged at the bottom end in the stock bin, the material guide port is matched with the filter plate in position, a soaking fan is arranged at the bottom end of the soaking bin, the output end of the soaking fan is connected with a second air guiding pipe, and the air port output end of the second air guide pipe is connected with a shunt pipe. According to the high-temperature molten slag waste heat high-efficiency recycling device, a first cooling pool and a second cooling pool are used for treating waste heat separately, waste heat utilization of different links can be conducted, and the adaptability is higher when the device is used in cooperation.

Description

technical field [0001] The invention relates to the technical field of industrial waste slag treatment equipment, in particular to a high-efficiency recycling device for waste heat of high-temperature slag. Background technique [0002] The converter steelmaking process is carried out in a molten reaction medium. The slag is the product of the pyrometallurgical steelmaking process. It refers to the glassy non-metallic substance coated on the surface of the molten metal after iron ore is smelted. It is mainly composed of metallurgical raw materials. The main function of the slag is to capture the oxidation products of impurity elements in the crude metal and separate the oxidation products from the main metal. During steelmaking, the added The slag-forming flux is fused with the oxidation products of impurity elements in the raw materials to form slag, which can not only remove S and P, but also absorb non-metallic inclusions, but the slag will also cause the following three ...

[0002] The converter steelmaking process is carried out in a molten reaction medium. The slag is the product of the pyrometallurgical steelmaking process. It refers to the glassy non-metallic substance coated on the surface of the molten metal after iron ore is smelted. It is mainly composed of metallurgical raw materials. The main function of the slag is to capture the oxidation products of impurity elements in the crude metal and separate the oxidation products from the main metal. During steelmaking, the added The slag-forming flux is fused with the oxidation products of impurity elements in the raw materials to form slag, which can not only remove S and P, but also absorb non-metallic inclusions, but the slag will also cause the following three hazards: first, erosion and Flush the furnace lining to reduce the service life of the furnace lining; second, lose molten steel and reduce the recovery rate; third, take away heat and increase smelting energy consumption

[0003] At present, the waste heat recovery of high-temperature slag is insufficient, and the flexibility of use is not high, resulting in a waste of thermal energy. Industrial production and daily life usually require the support of thermal energy, which is difficult to cooperate and make perfect use of. Therefore, a high-temperature slag is required.
