按制造廠提供的夾緊尺寸重新夾緊設(shè)備，尺寸應(yīng)均勻一致，壓緊尺寸的偏差應(yīng)不大于±0．2N(mm)(N。為板片總數(shù)），兩壓緊板間的平行度應(yīng)保持在2mm以內(nèi)。②在外漏部位上做好標(biāo)記，然后換熱器解體逐一排查解決，重新裝配或更換墊片和板片。③將開換熱器解體，對板片變形部位進(jìn)行修理或者更換板片。在沒有板片備件時可將變形部位板片暫時拆除后重新組裝使用。④重新組裝拆開的板片時，應(yīng)清潔板面，防止污物粘附著于墊片密封面。板式換熱器串液產(chǎn)生原因：①由于板材選擇不當(dāng)導(dǎo)致板片腐蝕產(chǎn)生裂紋或穿孔。②操作條件不符合設(shè)計要求。③板片冷沖壓成型后的殘余應(yīng)力和裝配中夾緊尺寸過小造成應(yīng)力腐蝕。④板片泄漏槽處有輕微滲漏，造成介質(zhì)中有害物質(zhì)（如C1）濃縮腐蝕板片。形成串液?，F(xiàn)場分析發(fā)現(xiàn)，系統(tǒng)運(yùn)行溫度、流量和濃度等工藝參數(shù)均超出設(shè)計條件，使用溫度遠(yuǎn)超出材料的適用范圍。采用飽和蒸汽作為一次側(cè)熱源的板式換熱器在運(yùn)行過程中容易發(fā)生板片腐蝕。導(dǎo)致產(chǎn)品串液。這是由于蒸汽溫度較高，設(shè)備運(yùn)行中很容易造成橡膠密封墊在高溫下失效，引起蒸汽外漏并在二道密封區(qū)域急速冷凝。隨著外漏的不斷進(jìn)行，冷凝殘液越聚越多，局部形成cl質(zhì)量濃度較高區(qū)域。 </p><p> 從而造成NH3泄漏以及NOx脫除不完全，使其易被氧化為SO3。SO3在空預(yù)器冷段(溫度177～232℃)濃縮成酸霧，腐蝕受熱面。在SCR反應(yīng)器出口SO3與逃逸的氨反應(yīng)生成***氫氨。在SO2氧化率的控制方面，主要取決于催化劑V2O5中的含量，釩的擔(dān)載量不能太高，通?？刂圃?%左右可減少SO2氧化。此外，采用提高催化劑活性組分。如WO3)含量，亦可***SO2氧化。這一點在脫硝系統(tǒng)安裝完成后，運(yùn)行中基本沒有調(diào)節(jié)手段。煙氣流場優(yōu)化煙氣流場的不均勻?qū)?dǎo)致脫硝系統(tǒng)出口氨逃逸率局部超標(biāo)，加快空預(yù)器傳熱元件上***氫氨的沉積。在氨逃逸量的控制方面可利用計算流體力學(xué)軟件優(yōu)化設(shè)計，對SCR脫硝裝置入口煙氣流量和流速分布進(jìn)行模擬，確定導(dǎo)流葉片的類型、數(shù)量和位置，同時，在運(yùn)行中針對經(jīng)常的運(yùn)行工況進(jìn)行調(diào)勻試驗。以使入口煙氣流速、溫度和濃度均勻；同時調(diào)整噴氨格柵各個噴口，使NH3混合均勻，保證脫硝出口的NOx含量和NH3均勻，避免局部氨逃逸量超標(biāo)，**終減少氨逃逸量。運(yùn)行中，由于機(jī)組負(fù)荷變化較大，雖然經(jīng)過調(diào)勻試驗，但無法保證在所有的工況下煙氣流場均穩(wěn)定均勻。因此，必然發(fā)生氨逃逸率局部偏大，長期低負(fù)荷運(yùn)行將造成空預(yù)器堵塞的可能性加大。板式空氣預(yù)熱器占地面積小。</p><div
