Environment cleaning, heat extraction and dry treatment system and process for high-temperature metallurgical slag

Abstract

The invention relates to an energy-saving, environment-friendly and safe environment cleaning, heat extraction and dry treatment system and an energy-saving, environment-friendly and safe environmentcleaning, heat extraction and dry treatment process for high-temperature metallurgical slag. The system comprises a sealed cabin, an annular rotating platform board, a slag ladle tipping machine, a steel slag flattening machine, a rotating chopper machine, a steel slag raising machine, a suspended slag discharging scraper machine and an air distribution plough, wherein the sealed cabin and the annular rotating platform board form a closed annular tunnel type closed space through rigid sealing and flexible sealing, the slag ladle tipping machine, the steel slag flattening machine, the rotatingchopper machine and the steel slag raising machine are sequentially arranged in the closed space, are connected and fixed with ground foundation via bolts through bearing seats and supports, stretch across two sides of the width direction of the annular rotating platform board and serve as main slag treatment equipment of the system; the suspended slag discharging scraper machine is fixed on a bracket upright post of the sealed cabin through a truss, stretches across the width position of the annular rotating platform board, and serves as tail slag discharging equipment of the system; and theair distribution plough is arranged in front of the suspended slag discharging scraper machine. The system has the advantages of high power, few faults, small maintenance amount and the like.

Description

technical field [0001] The invention relates to the technical field of metallurgical slag treatment, in particular to an energy-saving, environmentally friendly and safe high-temperature metallurgical slag environment cleaning, heat extraction, and dry treatment system and process. Background technique [0002] As we all know, more than ten percent of high-temperature slag will be produced in the process of iron and steel smelting, and the effective treatment of a large amount of high-temperature slag has always been the goal pursued by people, especially those with metallurgical aspirations; for this reason, many high-temperature slag treatment schemes have been researched and designed. But still can not meet the requirements and effects of aspects such as environmental protection, safety, energy saving. Contents of the invention [0003] The present invention aims to solve the above problems, thereby providing an energy-saving, environmentally friendly, and safe high-tem...
