style="text-indent:25px">換熱器在石油、化工、輕工、制藥、能源等工業(yè)生產(chǎn)中，常常用作把低溫流體加熱或者把高溫流體冷卻，把液體汽化成蒸汽或者把蒸汽冷凝成液體。換熱器既可是一種單元設(shè)備，如加熱器、冷卻器和凝汽器等；也可是某一工藝設(shè)備的組成部分，如氨合成塔內(nèi)的換熱器。換熱器是化工生產(chǎn)中重要的單元設(shè)備，根據(jù)統(tǒng)計，熱交換器的噸位約占整個工藝設(shè)備的20%有的甚至高達30%，其重要性可想而知。換熱器的大量使用有效的提高了能源的利用率，使企業(yè)成本降低，效益提高。福建換熱器價位噴淋式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。</p><div

style="text-indent:25px">完善的換熱器在設(shè)計或選型時應(yīng)滿足以下基本要求：（1）合理地實現(xiàn)所規(guī)定的工藝條件；（2）結(jié)構(gòu)安全可靠；（3）便于制造、安裝、操作和維修；（4）經(jīng)濟上合理。浮頭式換熱器的一端管板與殼體固定，而另一端的管板可在殼體內(nèi)自由浮動，殼體和管束對膨脹是自由的，故當(dāng)兩張介質(zhì)的溫差較大時，管束和殼體之間不產(chǎn)生溫差應(yīng)力。浮頭端設(shè)計成可拆結(jié)構(gòu)，使管束能容易的插入或抽出殼體。（也可設(shè)計成不可拆的）。這樣為檢修、清洗提供了方便。但該換熱器結(jié)構(gòu)較復(fù)雜，而且浮動端小蓋在操作時無法知道泄露情況。因此在安裝時要特別注意其密封。</p><p style="text-indent:25px">管殼式換熱器，研究表明工業(yè)水無論是淡水還是海水，都會有各種離子和溶解的氧氣，其中氯離子和氧的濃度變化，對金屬的腐蝕形狀起重要作用。另外，金屬結(jié)構(gòu)的復(fù)雜程度也會影響腐蝕形態(tài)。因此，管板與列管焊縫的腐蝕以孔蝕和縫隙腐蝕為主。從外觀看，管板表面會有許多腐蝕產(chǎn)物和積沉物，分布著大小不等的凹坑。以海水為介質(zhì)時，還會產(chǎn)生電偶腐蝕。化學(xué)腐蝕就是介質(zhì)的腐蝕，換熱器管板接觸各種各樣的化學(xué)介質(zhì)，就會受到化學(xué)介質(zhì)的腐蝕。另外，換熱器管板還會與換熱管之間產(chǎn)生一定的雙金屬腐蝕。間壁式換熱器是應(yīng)用較為普遍的換熱器。</p><div

style="text-indent:25px">管殼式換熱器由殼體、傳熱管束、管板、折流板（擋板）和管箱等部件組成。殼體多為圓筒形，內(nèi)部裝有管束，管束兩端固定在管板上。進行換熱的冷熱兩種流體，一種在管內(nèi)流動，稱為管程流體；另一種在管外流動，稱為殼程流體。為提高管外流體的傳熱分系數(shù)，通常在殼體內(nèi)安裝若干擋板。擋板可提高殼程流體速度，迫使流體按規(guī)定路程多次橫向通過管束，增強流體湍流程度。換熱管在管板上可按等邊三角形或正方形排列。等邊三角形排列較緊湊，管外流體湍動程度高，傳熱分系數(shù)大；正方形排列則管外清洗方便，適用于易結(jié)垢的流體。管殼式換熱器內(nèi)部裝有平行管束或者螺旋管，管束兩端固定于管板上。福建換熱器價位</p><p

style="text-indent:25px">對于一些新系統(tǒng)來說，不能馬上與換熱器進行交替使用，首先需把新的系統(tǒng)在指定的時間段運行，讓它有了一個運行模式后，此時方可以把換熱器并入系統(tǒng)中使用，這樣做的目的完全是為了避免管網(wǎng)中的雜質(zhì)破壞換熱器設(shè)備。行業(yè)狀況：換熱器在石油、化工、輕工、制藥、能源等工業(yè)生產(chǎn)中，常常用作把低溫流體加熱或者把高溫流體冷卻，把液體汽化成蒸汽或者把蒸汽冷凝成液體。換熱器既可是一種單元設(shè)備，如加熱器、冷卻器和凝汽器等；也可是某一工藝設(shè)備的組成部分，如氨合成塔內(nèi)的換熱器。福建換熱器價位</p><p
