山西焦煤西山煤電(dian)武(wu)鄉西山發電(dian)有限責任公司此次改造(zao)采用SPC—3D脫硫(liu)(liu)除塵(chen)一體(ti)化技(ji)術(shu)和脫銷增加(jia)一層催化劑方案。對(dui)脫硫(liu)(liu)吸收塔采用液壓整體(ti)提升(sheng)技(ji)術(shu)抬高了3.6m，對(dui)原(yuan)凈煙(yan)道(dao)進(jin)行(xing)了改造(zao)，更(geng)換(huan)容量小(xiao)的設備。增加(jia)了管(guan)式除塵(chen)器。工(gong)程脫硫(liu)(liu)采用石(shi)灰石(shi)—石(shi)膏石(shi)濕(shi)法脫硫(liu)(liu)技(ji)術(shu)，脫硝(xiao)采用SCR選擇性催化還(huan)原(yuan)技(ji)術(shu)，煙(yan)氣中(zhong)的氮氧化物經過(guo)脫硝(xiao)反應器大(da)大(da)降低。經驗(yan)收測(ce)量，二氧化硫(liu)(liu)排(pai)(pai)放(fang)濃度(du)從(cong)(cong)200mg/Nm3減(jian)(jian)為35mg/Nm3，氮氧化物排(pai)(pai)放(fang)濃度(du)從(cong)(cong)100mg/Nm3減(jian)(jian)為50mg/Nm3以內(nei)，煙(yan)塵(chen)排(pai)(pai)放(fang)濃度(du)從(cong)(cong)30mg/Nm3減(jian)(jian)為2—3mg/Nm3。
通過改(gai)造，兩家(jia)電廠(chang)也將走出(chu)一條清潔(jie)發(fa)(fa)展(zhan)、綠色(se)發(fa)(fa)展(zhan)之路，為當(dang)地(di)的環境(jing)保護作出(chu)應(ying)有(you)貢獻。改(gai)造完(wan)成后，兩家(jia)電廠(chang)也將得到政府的專項補貼、電量獎勵。
