style="text-indent:25px">換熱器是將熱流體的部分熱量傳遞給冷流體的設(shè)備，又稱(chēng)熱交換器。換熱器是化工、石油、動(dòng)力、食品及其它許多工業(yè)部門(mén)的通用設(shè)備，在生產(chǎn)中占有重要地位。換熱器在形式上可分為臥式換熱器與立式換熱器兩種，它們的區(qū)別主要有：立式換熱器：穩(wěn)定安全，需要垂直鋪設(shè)，通常采用塔狀結(jié)構(gòu)；占地少，安裝空間凈高要求高，一般≮3.5m，要求塔裙高度較高，操作需要平臺(tái)，拆卸清洗比較麻煩；結(jié)構(gòu)緊湊，配管容易；冷熱兩種流體一般逆流；傳熱系數(shù)較大，加熱滯留時(shí)間短，換熱效果較好。福州板或換熱器組裝換熱器時(shí)也可采用螺旋扁管與光管混合方式。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="福州板或換熱器,換熱器" src="https://tyunfile.71360.com/UploadFile/wxmyzb/637395774114291808/1294943.png"></div><p style="text-indent:25px">陶瓷換熱器傳熱效率高，節(jié)能效果明顯，用以預(yù)熱助燃空氣或加熱某些過(guò)程的工藝氣體，可節(jié)約一次能源，燃料節(jié)約率可達(dá)30%－55%，并可強(qiáng)化工藝過(guò)程，明顯提高生產(chǎn)能力。陶瓷換熱器的生產(chǎn)工藝與窯具的生產(chǎn)工藝基本相同，導(dǎo)熱性與抗氧化性能是材料的主要應(yīng)用性能。它的原理是把陶瓷換熱器放置在煙道出口較近，溫度較高的地方，不需要摻冷風(fēng)及高溫保護(hù)，當(dāng)窯爐溫度1250-1450℃時(shí)，煙道出口的溫度應(yīng)是1000-1300℃，陶瓷換熱器回收余熱可達(dá)到450-750℃，將回收到的的熱空氣送進(jìn)窯爐與燃?xì)庑纬苫旌蠚膺M(jìn)行燃燒，這樣直接降低生產(chǎn)成本，增加經(jīng)濟(jì)效益。</p><p style="text-indent:25px">熱換器的鈍化處理：酸洗結(jié)束后，板式熱交換器表面的水垢和金屬氧化物絕大部分被溶解脫落，暴露出嶄新的金屬，極易腐蝕，因此在酸洗后，對(duì)換熱器板片進(jìn)行鈍化處理。清洗水垢的具體步驟沖冼：酸洗前，先對(duì)換熱器進(jìn)行開(kāi)式?jīng)_洗，使換熱器內(nèi)部沒(méi)有泥、垢等雜質(zhì)，這樣既能提高酸洗的效果，也可降低酸洗的耗酸量。將清洗液倒入清洗設(shè)備，然后再注入換熱器中。酸洗：將注滿酸溶液的換熱器靜態(tài)浸泡2h，然后連續(xù)動(dòng)態(tài)循環(huán)3-4h，其間每隔0.5h進(jìn)行正反交替清洗。酸洗結(jié)后，若酸液ph值大于2，酸液可重復(fù)使用，否則，應(yīng)將酸洗液稀釋中和后排掉。換熱器適用于冷熱流體溫度差不大,且殼程不需機(jī)械清洗時(shí)的換熱操作。</p><div

style="text-indent:25px">換熱器的冷凝器也有立式及臥式兩種。臥式和立式冷凝器二者除安放位置和水的分配不同外，水的溫升和用水量也不一樣。立式冷凝器的冷卻水是沿著重力沿管內(nèi)壁往下的流，只能是單行程，故要得到足夠大的傳熱系數(shù)，就必須使用大量的水。臥式冷凝器是用泵將冷卻水壓送到冷卻管內(nèi)，故可制成多行程式冷凝器，且冷卻水可以得到足夠大的流速和溫升。所以臥式冷凝器用少量的冷卻水就可以得到足夠大的傳熱效果。但過(guò)分地加大流速，傳熱系數(shù)增大不多，而冷卻水泵的功耗卻明顯增加。直接接觸式換熱器又被稱(chēng)為混合式換熱器，這種換熱器是兩種流體直接接觸，彼此混合進(jìn)行換熱的設(shè)備。福州板或換熱器</p><p style="text-indent:25px">換熱器當(dāng)浮頭出的鉤圈拆除后，即可將管束從殼體內(nèi)抽出。福州板或換熱器</p><p style="text-indent:25px">噴淋式換熱器：這種換熱器是將換熱管成排地固定在鋼架上，熱流體在管內(nèi)流動(dòng)，冷卻水從上方噴淋裝置均勻淋下，故也稱(chēng)噴淋式冷卻器.噴淋式換熱器的管外是一層湍動(dòng)程度較高的液膜，管外給熱系數(shù)較沉浸式增大很多.另外，這種換熱器大多放置在空氣流通之處，冷卻水的蒸發(fā)亦帶走一部分熱量，可起到降低冷卻水溫度，增大傳熱推動(dòng)力的作用.因此，和沉浸式相比，噴淋式換熱器的傳熱效果大有改善。套管式換熱器套管式換熱器是由直徑不同的直管制成的同心套管，并由U形彎頭連接而成.在這種換熱器中，一種流體走管內(nèi)，另一種流體走環(huán)隙，兩者皆可得到較高的流速，故傳熱系數(shù)較大.另外，在套管換熱器中。福州板或換熱器</p><p
