摘要/Abstract

摘要： 某600 MW燃煤机组为实现超低排放改造，将原脱硫塔除雾器（二级屋脊式除雾器+一级管式除雾器）改造更换为冷凝式除雾器。该冷凝式除雾器由三级屋脊式高效除雾器和冷凝湿膜层组成，另设有由喷淋冷却水泵及闭式冷却设备组成的塔外冷却站。在100%和50%负荷工况下，通过调整冷却站运行模式，控制冷凝湿膜层投运或退出，现场测试了不同工况下脱硫系统雾滴排放量及整体协同洗尘效率和SO₃脱除率。测试结果表明，冷却站换热量对冷凝式除雾器运行效果有较大的影响，提高冷却站换热量有助于提高雾滴、烟尘及SO₃的脱除效果。

Abstract: In order to realize the ultra-low emissions, a 600 MW coal-fired unit is retrofitted by replacing the original demister in desulphurization tower (two-stage roof type demister plus one-stage tubular demister) with the condensed mist eliminator. The condensed mist eliminator consists of three-stage ridge-type high-efficiency demister and condensed wet layer. In addition, a cooling station outside the tower composed of a spray cooling water pump and a closed cooling equipment is provided. The droplet emissions as well as overall collaborative efficiency of dust collection and SO₃ desulfurization efficiency of whole desulfurization system were tested under 50% and 100% working conditions respectively by adjusting the operating mode of outside cooling tower of the condensing demister. The test results show that the thermal capacity of the cooling station has significant influence on the operation performance of the condensing mist eliminator. Enhancing the heat transfer at the cooling station is helpful to improve the removal efficiency of droplet, dust and SO₃.

Key words: coal-fired power unit, desnifurization system, condensing mist eliminator, cooling station, synergistic dust removal, performance evaluation of synergistic removal
