Novel energy-saving emission-reduction sintering machine system and sintering method

Abstract

The invention relates to a novel energy-saving emission-reduction sintering machine system and a sintering method. The novel energy-saving emission-reduction sintering machine system comprises a sintering machine room, wherein flue gas circulating systems are arranged on the two side faces of the sintering machine room, sintering flue gas generated by the sintering machine room is discharged through a flue after dedusting and desulfuration, sintered minerals in the sintering machine room are crushed, are cooled, and are screened in a finished product screening room I, a finished product screening room II and a finished product screening room III in sequence to obtain finished product broken particles, the finished product broken particles are conveyed to a finished product storage yard, broken particles which are not screened out in the finished product screening room III enter a burdening room, spraying is carried out minerals prepared in the burdening room through a urine solution spraying device, the minerals are mixed through a primary mixing room and a secondary mixing room in sequence, and the mixed minerals are evenly arranged in the sintering machine room through a mixed material distribution device to be sintered. The novel energy-saving emission-reduction sintering machine system and the sintering method make full use of waste heat, reduce energy consumption of the sintering technology, and remarkably reduce emission of organic pollutants such as NOx and dioxin.

Description

technical field [0001] The invention relates to the technical field of mineral sintering and sintering equipment, in particular to a novel energy-saving and emission-reducing sintering machine system and a sintering method. Background technique [0002] Sintering is an important process in the production chain of iron and steel complexes. With the development of the iron and steel industry, the demand for iron ore is increasing. However, there are fewer and fewer rich ores that are directly put into the furnace for ironmaking, and a large amount of lean ore resources must be mined and used. Smelting lean ore directly into the furnace will deteriorate the production index of the blast furnace. Therefore, lean ore is processed to obtain concentrate powder through mineral processing. The fine ore produced during the mining and processing of concentrate and rich ore needs to be agglomerated before it can be used in blast furnace ironmaking. The function of the sintering machi...
