[0002] The gasification furnace slag is the product generated by a series of decomposition and combination reactions of mineral substances in coal during the coal gasification process. The traditional treatment method of the gasification furnace slag is to bury it underground, which is simple and low in cost, but occupies land resources and may pollute the soil and groundwater. At present, in order to meet the green and low-carbon resource development concept, the gasification furnace slag is processed to realize resource recycling, which has the advantages of environmental protection and economy.

[0003] During the processing and treatment of the gasification furnace slag, the gasification furnace slag needs to be calcined to remove a small amount of organic matter, moisture and oxides and other impurities in the gasification furnace slag, so as to activate the gasification furnace slag and improve the utilization degree of the gasification furnace slag. The equipment for calcining the gasification furnace slag mostly adopts a calcining furnace, such as the Chinese patent document with the publication number CN216347786U, which discloses a slag calcining device.

The gasification furnace slag is placed below the car bottom furnace during calcination, and the car bottom furnace completes the calcination during movement. However, since the thermocouple of the car bottom furnace conducts heat from top to bottom, and the gasification furnace slag is stacked in layers, the gasification furnace slag on the surface that has been calcined will insulate heat, so that the gasification furnace slag in the lower layer cannot be completely heated, and the impurities in the gasification furnace slag cannot be completely removed, resulting in incomplete activation of the gasification furnace slag. Furthermore, during subsequent processing such as crushing or dissolution after calcination, the gasification furnace slag may accumulate at the inlet of the crusher or be difficult to dissolve, thereby posing a risk of blocking the equipment.
