Abstract

The invention discloses a primary cooling section device and method for slag granulation. The primary cooling section device for slag granulation is arranged between a granulation chamber and discharge equipment and comprises an inner ring and an outer ring, wherein the inner ring and the outer ring are each of a jacket structure, and cooling water is introduced into a jacket; an annular space is formed between the outer wall of the inner ring and the inner wall of the outer ring; multiple circles of water-cooling turnover plate structures are arranged in the annular space, and the multiple circles of water-cooling turnover plate structures are sequentially and alternately mounted on the outer wall of the inner ring and the inner wall of the outer ring from top to bottom; the cooling water is introduced into the water-cooling turnover plate structures; and slag particles descend in the annular space from top to bottom in a broken line mode and are cooled through the water-cooling turnover plate structures. According to the primary cooling section device and method, high-temperature slag particles granulated and cooled by the granulation chamber can be further cooled, so that the condition of secondary adhesion of the slag particles due to over-high temperature and transient accumulation is avoided.

Description

technical field [0001] The invention relates to the technical field of slag granulation devices, in particular to a device and method for the primary cooling section of slag granulation. Background technique [0002] The main equipment for slag granulation generally includes: a granulation chamber (with a granulation turntable inside) and discharge equipment. In the actual use process, the inventors of the present application found that due to the influence of factors such as slag temperature, viscosity, and granulation turntable speed, the particle size of the slag particles thrown out by the granulation turntable is often too large, and the slag particles in the granulation chamber Insufficient cooling, the internal temperature of the particles is still high, and the accumulation of high-temperature slag particles in the discharge equipment for a short time is prone to secondary adhesion and other problems. Contents of the invention [0003] Based on this, the object of...
