摘要

选取一个100 MW燃煤电厂对氯化铜改性氧化铝和氯化铜改性沸石进行喷射脱汞实验

应用EPA 30B标准方法对静电除尘器(ESP)前后烟气中的汞价态分布进行了采样和测试.研究了吸附剂喷射量对烟气中汞脱除率的影响.现场测试的汞平衡结果为77.1%～111.5%.经修正的汞平衡结果表明

吸附剂喷射量越大

脱汞率越高.改性氧化铝的脱汞率最高可达30.6%

改性沸石的脱汞率最高可达29.2%.喷射非碳基吸附剂后烟气中元素汞(Hg0)显著下降

在喷射量为0.22 g·m-3时

两种吸附剂可将烟气中Hg0比例由40%降低至22%左右

减少的Hg0主要转化为HgP.非碳基吸附剂与湿法脱硫(WFGD)系统协同使用可以有效减少Hg0向大气中的排放.

Abstract

The mercury removal from the flue gas discharged from a 100 MW coal-fired power plant in China by non-carbon sorbents CuCl2 impregnated alumina and zeolite were experimentally investigated in this paper. When the sorbent were added into

the mercury speciation in flue gas across ESP was directly sampled and analyzed using EPA 30B standard method. The effect of injection rate was studied. The mercury balances measured on-site were between 77.1%—111.5%

and the results of mercury balance after correction suggested that the rates of mercury removal increased with increase of injecting amounts

and was up to 30.6% for modified alumina and 29.2% for modified zeolite. The Hg0 content in flue gas reduced considerably after sorbent injection

and decreased from 40% to 22% when the sorbent injection rate was 0.22 g·m-3. Non-carbon sorbent injection combined with WFGD system could be an effective technology for controlling mercury emission of coal-fired power plant.
