Abstract

The invention discloses a system and a method for generating steam by directly utilizing sensible heat of a high-temperature sintering ore material. The system mainly comprises a steam generator which is placed under a discharge port of the high-temperature sintering ore material of a sintering machine. The method comprises the following steps: the sintering ore material at the temperature of about 1000 DEG C is discharged from the sintering machine and is crushed through a crusher, and the sintering machine falls into a furnace hearth of a steam generator and passes through an overheat steam pipe, a heater water pipe and a vertical evaporation pipe which are arranged in the furnace hearth from top to bottom; the sintering ore material is discharged from the bottom after being cooled to be below 150 DEG C through direct contact heat conduction of the sintering ore material and a be-heated pipe, heat radiation and convection heat transfer of air flow which is sucked by an exhaust fan and is heated through a sintering ore material layer in the furnace hearth from bottom to top; the water and the steam in the pipe are heated to generate overheat steam at the temperature of over 500 DEG C for power generation; and finally, the cooling of the high-temperature sintering ore material is completed in one device and the overheat steam is generated by utilizing sensible heat. The system and the method have compact structure, high utilization ratio of sensible heat and wide energy-saving application prospect in the field of metallurgical industry.

Description

Technical field:

[0001] The invention relates to cooling of high-temperature solid materials and recovery of sensible heat, in particular to a system and method for directly cooling high-temperature sintered ore materials and utilizing the sensible heat to generate steam. Background technique:

[0002] High-temperature solid materials produced in many industrial production processes, such as sinter, slag, ore, and solid materials, need to be cooled. The sensible heat of high-temperature solid materials released during the cooling process is heat energy that can be recycled. In the metallurgical industry, the temperature of the sintered ore produced by the sintering machine is as high as 1000°C, and it must be cooled before it can enter the next smelting process. In order to utilize the heat energy released during the process of cooling high-temperature minerals, the existing traditional method is to move the high-temperature minerals on a ring or belt-type slag cooler, and a...
