摘要
随着我经济日益腾飞,环境问题越来越受到重视,而钢铁企业二氧化硫的排放总量仅赐予燃煤电厂。本文结合钢铁行业烧结烟气的特点,评述了目前几种烧结烟气脱硫技术,指出钢铁企业烧结烟气脱硫要结合烧结烟气的特点和钢铁企业的实际情况,按照循环经济的模式,实现资源、回收。截止到目前为止,由于二氧化硫污染治理费用高,国内尚无成熟可靠的专项技术措施,钢铁企业的烧结机大多没有设置专项脱硫装置。因此,在当前全均面积大幅度曾加的情况下,加大烧结烟气水平脱硫专项技术装备的研究开发,尽快解决烧结机脱硫问题,已成为钢铁企业实现循环经济和可持续发展的重大课题。

ABSTRACT
I take off with the economy, more and more attention to environmental issues, and iron and steel enterprises dioxide emissions of coal-fired power plant is only given. In this paper, iron and steel industry sintering flue gas characteristics, review the current number of sintering flue gas desulfurization technology, pointed out that the iron and steel enterprises should sintering flue gas desulfurization characteristics of sintering flue gas and the actual situation of iron and steel enterprises, according to the mode of circular economy, resource recovery. As of now, due to the high cost of sulfur dioxide pollution control, there is no reliable national special technical measures of the sintering machine iron and steel enterprises do not have any specific desulfurization device settings. Therefore,
Sintering machine in the current national average size of a substantial increase in cases has increased the level of sintering flue gas desulfurization equipment, special technical research and development, as soon as possible to resolve the issue desulfuration sintering machine, iron and steel enterprises have e a circular economy and sustainable development topics
Keywords: Environment; sintering flue gas; technical measures; device equipment
引言
铁矿粉烧结是将含或细粒料进行高温加热,在不完全熔化的条件下烧结成块的过程。它是许多物理化学变化的综合过程,这个过程错综复杂,在积分中设置更段的时间内,烧结料就因强烈的热交换从70℃以下被加热到1200-1400℃,
