Abstract

A dry granulation rotating disc is applied to a granulation chamber for dry granulation, the rotating disc comprises a shell, a water tank, a water inlet pipe and a rotating pipe body, the upper end face of the shell is a surface for receiving molten slag, the upper end of the rotating pipe body is vertically connected to the lower end of the shell, a pipe cavity of the rotating pipe body is communicated with the interior of the shell, the lower end of the rotating pipe body penetrates into the water tank, and the water tank is arranged in the water tank. The water inlet pipe is arranged in the rotating pipe body, the upper end of the water inlet pipe extends into the shell, and the lower end of the water inlet pipe extends out of the water tank. According to the dry-method granulation rotating disc, the rotating disc adopts an open type water cooling mode, the water inlet pipe does not rotate along with the rotating disc and the rotating pipe body, and a rotating connector is not needed.

Description

technical field [0001] The invention relates to the technical field of smelting slag treatment, in particular to a dry granulation turntable. Background technique [0002] High-temperature liquid slag is a by-product of the steel production process. Its discharge temperature is as high as 1500°C and contains a large amount of high-temperature waste heat. The sensible heat and low-temperature waste heat resources of high-temperature liquid slag have not been well recycled so far. Slag dumping causes waste of resources, pollutes the environment, destroys the ecological landscape, occupies land, and has not been well utilized. The slag treatment methods at home and abroad mainly include hot stuffing, hot splashing, water quenching, wind quenching, and roller method. However, the above-mentioned methods have more or less disadvantages such as large investment, large land occupation, heavy environmental pollution, and poor treatment effect. Contents of the invention [0003] ...
