Sintering oxygen enrichment system

Abstract

The invention discloses a sintering oxygen enrichment system. The sintering oxygen enrichment system comprises an oxygen production pressure adjusting station; medium-pressure oxygen is fed to a sintering factory through a pipe network after being adjusted the pressure by the oxygen production pressure adjusting station, and is conveyed to an oxygen adjusting valve through a pipe at the sintering factory; an oxygen flow meter is mounted in front of the oxygen adjusting valve; and then, the oxygen is conveyed to an oxygen quick cutting valve through a pipe, is conveyed to a gas mixer through a pipe, and is fed in two combustion assisting fans through pipes. The sintering oxygen enrichment system has the following beneficial effects: the sintering oxygen enrichment system facilitates to reduce the internal circulation reverse ore rate and increase the sintering yield, and can increase the sintering yield by above 10%; meanwhile, an oxygen-enriched ignition process is adopted to prominently improve the sintering ignition quality and to achieve obvious effects on increment of sintering ores, energy conservation and improvement of the product quality; and in addition, for sintering factories using blast furnace gas and difficult to obtain other calorific value gas to ignite, the oxygen-enriched ignition technology is adopted to also achieve prominent improvement effects.

Description

technical field [0001] The invention relates to the field of sintering oxygen enrichment, in particular to a sintering oxygen enrichment system. Background technique [0002] Sintering ignition refers to a process of sintering concentrate powder and rich ore powder with different components and particle sizes into blocks in a large-scale ferrous metallurgical sintering plant, and partially eliminating harmful impurities such as sulfur and phosphorus contained in the ore. Sintering ignition generally requires the use of blast furnace gas as fuel and mixed combustion with air. With the continuous development of sintering ignition technology, some new problems have appeared in the actual application of traditional sintering ignition, such as the low temperature of sintering ignition furnace, Poor ignition quality not only affects the quality of sintered ore, but also easily causes the quality of sintered products to be unstable. Therefore, it is necessary to design a sintered o...

Problems solved by technology

Sintering ignition generally requires the use of blast furnace gas as fuel and mixed combustion with air. With the continuous development of sintering ignition technology, some new problems have appeared in the actual application of traditional sintering ignition, such as the low temperature of sintering ignition furnace, The ignition quality is poor, which not only affects the quality of sintered ore, but also easily causes the quality of sintered products to be unstable, so it is necessary to design a sintered oxygen-enriched system to solve the above problems
