當(dāng)前煙氣脫硝除塵凈化技術(shù)主要分別在脫硝單元和除塵單元完成:脫硝過(guò)程主要包括基于V-W-Ti催化體系的選擇性催化還原（SCR）以及選擇性非催化還原技術(shù)（SNCR）;除塵過(guò)程則包括濕法除塵、電除塵、過(guò)濾除塵等多種工藝技術(shù)。脫硝與除塵單元的獨(dú)立運(yùn)行不僅增加占地空間,還顯著提升設(shè)備投資和運(yùn)行成本。因此,如何將煙氣脫硝除塵一體化,縮短工藝流程,降低工藝成本,是當(dāng)前煙氣脫硝除塵凈化領(lǐng)域發(fā)展的一個(gè)重要方向。當(dāng)前的研究主要集中于脫硝除塵工藝耦合與優(yōu)化以降低工程和操作成本,但是由于當(dāng)前脫硝與除塵工藝的相對(duì)獨(dú)立性,如何在同一單元實(shí)現(xiàn)燃燒煙氣脫硝除塵凈化依然是該領(lǐng)域面臨的重大挑戰(zhàn)。催化濾芯或催化濾袋,可實(shí)現(xiàn)脫硝與除塵單元在同一操作單元內(nèi)完成,可顯著降低煙氣脫硝除塵的工藝和運(yùn)行成本,并成為當(dāng)前煙氣凈化領(lǐng)域的一個(gè)新興熱點(diǎn)方向。針對(duì)中高溫?zé)煔鈨艋?本文首先研發(fā)了可同時(shí)去除NOx和灰塵的V-W-Mo-Ti催化濾芯,并在實(shí)驗(yàn)室和中試現(xiàn)場(chǎng)進(jìn)行測(cè)試。研究了催化劑漿料,催化劑負(fù)載量和空速,以進(jìn)一步優(yōu)化催化濾芯以獲得更好的SCR活性和工業(yè)實(shí)用性。此外,在實(shí)驗(yàn)室條件下研究了粉塵對(duì)催化活性和壓降的影響,作為中試應(yīng)用的數(shù)據(jù)支持。2...
