化工設(shè)備換熱器之列管式換熱器1、換熱器結(jié)構(gòu)原理列管式換熱器是目前化工生產(chǎn)上應(yīng)用廣的一種換熱器。它主要由殼體、管板、換熱管、封頭、折流擋板等組成。所需材質(zhì)，可分別采用普通碳鋼、紫銅、或不銹鋼制作。在進(jìn)行換熱時，一種流體由封頭的連結(jié)管處進(jìn)入，在管中流動，從封頭另一端的出口管流出，這稱之管程；另一種流體由殼體的接管進(jìn)入，從殼體上的另一接管處流出，這稱為殼程列管式換熱器。為增加殼程流體流速，往往在殼內(nèi)安裝一些數(shù)目與管束相互垂直的折流擋板。折流擋板不僅不會讓流體短路、增加流體流速，還迫使流體按規(guī)定路徑多次錯流通過管束，使湍動程度大為增加。常用的折流擋板有圓缺形和圓盤形兩種，前者較為常用。2、種類（1）固定管板式換熱器（2）浮頭式換熱器（3）填料函式換熱器（4）U型管式換熱器。

管程結(jié)構(gòu)①換熱管規(guī)格和排列的選擇換熱管直徑越小，換熱器單位體積的傳熱面積越大。因此，對于潔凈的流體管徑可取小些。但對于不潔凈或易結(jié)垢的流體，管徑應(yīng)取得大些，以免堵塞?？紤]到制造和維修的方便，加熱管的規(guī)格不宜過多。按選定的管徑和流速確定管子數(shù)目，再根據(jù)所需傳熱面積，求得管子長度。實際所取管長應(yīng)根據(jù)出廠的鋼管長度合理截用。我國生產(chǎn)的鋼管長度多為6m、9m，故系列標(biāo)準(zhǔn)中管長有，2m，3m，，6m和9m六種，其中以3m和6m更為普遍。同時，管子的長度又應(yīng)與管徑相適應(yīng)，一般管長與管徑之比，即L/D約為4～6。管子的排列方式有等邊三角形和正方形兩種（圖，圖）。與正方形相比，等邊三角形排列比較緊湊，管外流體湍動程度高，表面?zhèn)鳠嵯禂?shù)大。正方形排列雖比較松散，傳熱效果也較差，但管外清洗方便，對易結(jié)垢流體更為適用。如將正方形排列的管束斜轉(zhuǎn)45°安裝，可在一定程度上提高表面?zhèn)鳠嵯禂?shù)。②管板固定管板式換熱器的兩端管板采用焊接方法與殼體連接固定。管板的作用是將受熱管束連接在一起，并將管程和殼程的流體分隔開來。③封頭和管箱封頭封頭有方形和圓形兩種，方形用于直徑小的殼體(一般小于400mm)，圓形用于大直徑的殼體。
