Problems solved by technology

In the process of pressure hot stuffiness, the temperature of steel slag entering the tank is greater than 300°C to meet the process requirements. Excessively high tank temperature not only prolongs the time of pressure hot stuffiness, but also easily causes safety problems

Abstract

The invention discloses a steel slag waste heat utilization device and an operation mode thereof, and belongs to the field of recycling equipment. According to the technical scheme, the operation modeis characterized by comprising the steps that firstly, high-temperature blocky steel slag rolled and crushed by a roller press is discharged to a conveying tool; then, the high-temperature blocky steel slag is conveyed to a high position through the conveying tool and loaded into a high-temperature blocky steel slag heat taking device through a feeding port of the high-temperature blocky steel slag heat taking device; then, a fan supplies air, and cold air is fed into the high-temperature blocky steel slag heat taking device through an air distribution device of the high-temperature blocky steel slag heat taking device and exchanges heat with the high-temperature steel slag in the high-temperature blocky steel slag heat taking device; then, high-temperature air obtained after heat exchange and temperature rise is discharged from a hot air outlet in the top of the high-temperature blocky steel slag heat taking device and then introduced into a hot waste heat boiler for waste heat utilization; and then, the fan stops supplying air, and the cooled steel slag is discharged from a discharging port in the bottom of the high-temperature blocky steel slag heat taking device and loaded into a steel slag tank car. Therefore, effective utilization of steel slag waste heat is realized.

Description

technical field [0001] The invention belongs to the field of recycling equipment, and in particular relates to a steel slag waste heat utilization device and its operation mode. Background technique [0002] Roller crushing of steel slag-waste heat self-decomposition with pressure hot stuffy process technology, realized the continuous, equipment and automation of steel slag treatment for the first time in my country. The processing process is mainly divided into two steps: high-temperature molten steel slag at about 1400 ℃ enters roll crushing area, water cooling while rolling crushing. The steel slag after rolling crushing and cooling is about 800°C; the steel slag at about 800°C enters the pressure-heated stuffy tank (7), and is cooled intermittently in a closed environment to complete the powdering of steel slag and the separation of slag and steel. In the process of pressure hot stuffiness, the temperature of steel slag entering the tank is greater than 300°C to meet the...
