摘要

基于高湿烟气降温时大量水蒸气冷凝过程中的相变团聚和潜热释放

设计开发了集除尘、节水和汽化潜热回收一体化的湿式相变凝聚系统

并在首次独立应用后

实现了280 t/h燃煤锅炉粉尘超低排放。该系统布置在湿法烟气脱硫系统(WFGD)与烟囱之间

采用锅炉补水(除盐水)作为冷却介质

在脱除烟气颗粒物同时

实现深度节水和烟气余热回收。实际应用结果表明:在90%负荷和75%负荷2个测试工况下

该系统对颗粒物的脱除效率分别为53.05%、71.11%

颗粒物排放质量浓度均低于5 mg/m~3

最大收水量为4.32 t/h

最高回收热量为3.59 MW。

Abstract

The wet phase transition agglomeration system(WPTA) integrating dust removal

water saving

and latent heat recovery for vaporization is designed and developed based on the phase transition agglomeration and latent heat release during the condensation of large quantities of water vapor when the high humidity smoke is cooled. After the first independent application

ultra-low dust emission from 280 t/h coal-fired boiler is achieved.The system is arranged between the wet flue gas desulfurization system(WFGD) and the chimney

and the make-up water for boiler is used as the cooling medium. The system removes particulates from smoke and achieves deep water saving and waste heat recovery. After application of WPTA

the field measurement results show that under two test conditions of 90% load and 75% load

the particulate removal efficiencies of WPTA is 53.05% and 71.11%

respectively. The particulate emission concentration is lower than 5 mg/m~3

the maximum mass of recovery water is 4.32 t/h and the maximum mass of heat recovery is 3.59 MW.
