燃煤电厂海水烟气脱硫工艺原理初探

PRIMARY RESEARCH ON THE PRINCIPLE OF SEAWATER FLUE GAS DESULPHURIZATION FOR POWER

海水烟气脱硫工艺是利用天然的纯海水（燃煤电厂可直接利用电厂的冷却循环水）作为烟气中ＳＯ２的吸收剂，无需其它任何添加剂，也不产生任何废弃物，具有技术成熟、工艺简单、系统运行可靠、脱硫效率高（理论脱硫效率可达９８％）和投资运行费用低等特点，目前在一些国家和地区已得到日益广泛的应用。本文是在部分模拟试验的基础上，对海水烟气脱硫工艺进行了简单的阐述。

The process of flue gas desulphurization by seawater is utilizing seawater as the absorbent of SO 2 in the flue gas without any additive and any yield of waste,which is characterized by proven technology,simple process,reliable operation,high efficiency of desulphurization and low operational cost.Based on the simulated experiment,the principle of the process was introduced in the paper.
