十多年前,我们已经研制了无污染节能型烧结方法。这种新技术已应用于住友金属工业公司小仓钢铁厂烧结面积为222米~2的No.3烧结设备中。该设备于1981年11月投入生产,运转一直良好。这种设有脱硫脱氮废气循环式烧结设备的优点如下: (1) 进入大气的废气量显著减少(约是过去的1/3)。(2) 空气污染控制设备如电除尘器和脱硫设备的规格显著减小(设备费用约是过去的1/3)。(3) 废气温度从150℃降低到100℃,提高了电除尘器的效率。(4) 焦粉配比降低(约4%). (5) 废热回收量显著增加(约30%)。(6) 电耗减少(约40%)。
Ten years ago, we have developed a pollution-free energy-saving sintering method. This new technology has been used in Sumitomo Metal Industries Co., Ltd. Kokura Iron Works sintering area of 222 m ~ 2 No.3 sintering equipment. The equipment was put into production in November 1981 and has been operating well. The advantages of this desulfurization and denitrification exhaust gas recirculation sintering equipment are as follows: (1) The amount of exhaust gas entering the atmosphere is significantly reduced (about one third of the past). (2) Specifications of air pollution control equipment such as electrostatic precipitators and desulphurization equipment are significantly reduced (equipment cost is about 1/3 of the past). (3) The temperature of the exhaust gas is reduced from 150 ° C to 100 ° C, which increases the efficiency of the electrostatic precipitator. (4) Reduced coke ratio (about 4%) (5) Significant increase in waste heat recovery (about 30%). (6) reduce power consumption (about 40%).
