Problems solved by technology
[0003] Pouring high-temperature molten slag directly into the pool will lose a lot of recyclable heat, resulting in waste of heat resources, and the water consumption is large, so water needs to be replaced. The presence of large-volume high-temperature molten slag occupies a large space and is inconvenient. Increase its cooling speed, and some of the slag granulation degree is not completely eliminated in the injection granulation structure of some high-temperature molten slag spray granulation equipment, resulting in the granulation structure to be improved

The invention belongs to the technical field of granulating devices, and particularly relates to a high-temperature melting furnace slag jetting and granulating device which comprises a hopper frame,a dropping pipe, a circular arc strip hole, a graphite slip ring, air injection fine holes, a cylindrical filter drum, a sealed cap, a T-shaped ring plug, a guiding pipe, a heat absorbing pipe, a tank, an air injecting pipe, an annular frame, a jetting cylinder, a stopping cylinder, a sliding chute, a reset spring, a strip-shaped hole and a convex block. The high-temperature melting furnace slag jetting and granulating device provided by the invention is reasonable in design; a high-temperature melting furnace slag is jetted and granulated by adopting high-speed saturated steam jetting and a tornado flow state, so that furnace slag particles with large mass volume are continuously granulated conveniently; meanwhile, the high-temperature melting furnace slag is favorably cooled, so that a heat absorption recycling function is realized; the granulated particles can be conveniently concentrated and accumulated together so as to be treated; and through the four air injection fine holes annularly distributed in the bottom part in the jetting cylinder, a steam flow in the jetting cylinder flows at the tornado state.
Description
technical field [0001] The invention belongs to the technical field of granulation devices, in particular to a jet granulation device for high-temperature molten slag. Background technique [0002] Metallurgy, phosphorus chemical industry, energy conservation and environmental protection and other fields all produce high-temperature molten slag as a by-product in the production process. These high-temperature molten slags have the characteristics of high temperature and high enthalpy, and belong to high-quality waste heat resources. For example, blast furnace slag is a blast furnace ironmaking The temperature of the by-products discharged from the blast furnace is 1450-1650 ℃, and the heat enthalpy is about 1870MJ / t. Therefore, the waste heat recovery and comprehensive utilization of high-temperature molten slag are done well, which is an effective way to save energy and reduce consumption in related industries. [0003] Pouring high-temperature molten slag directly into the...
