殼管式換熱器-固定管板

殼管式換熱器技術(shù)參數(shù)

殼管式換熱器是工業(yè)領(lǐng)域應(yīng)用廣泛的換熱設(shè)備之一,適用于高壓、高溫及復(fù)雜介質(zhì)工況,其核心參數(shù)如下:

一、主要技術(shù)參數(shù)

參數(shù) 典型值/范圍 備注
設(shè)計標(biāo)準(zhǔn) ASME VIII Div.1 / TEMA / GB 151 國際通用標(biāo)準(zhǔn)
換熱面積 1~2000 m2 可定制非標(biāo)尺寸
設(shè)計壓力(殼程/管程) 0.6~15 MPa (6~150 bar) 超高壓型可達30 MPa
設(shè)計溫度 -196°C ~ +600°C 深冷至高溫全覆蓋
殼體材質(zhì) 碳鋼(Q345R)/ SS304 / SS316L / 哈氏合金 耐腐蝕選項
管束材質(zhì) SS304 / SS316L / 銅鎳合金 / 鈦 抗結(jié)垢設(shè)計
管徑/管長 Φ10~Φ50 mm / 1~12 m U型/直管可選
管板連接方式 焊接/脹接/焊接+脹接 防泄漏設(shè)計
管程數(shù) 1~8程 多流程優(yōu)化溫差
折流板類型 單弓/雙弓/圓盤式 控制殼程流態(tài)
接口標(biāo)準(zhǔn) ANSI / DIN / GB / JIS法蘭 DN25~DN1000

二、結(jié)構(gòu)特點

  • o 多流程設(shè)計 – 通過增加管程數(shù)提升傳熱溫差(ΔT)。
  • o 抗振防沖蝕 – 折流板優(yōu)化殼程流體分布,減少管束振動。
  • o 模塊化維護 – 可拆卸管束(浮頭式/AES型)便于清洗。
  • o 強化傳熱 – 可選波紋管、螺旋槽管等高效傳熱管。

三、典型應(yīng)用

  • o 石油化工:原油預(yù)熱、反應(yīng)器冷卻、溶劑冷凝
  • o 電力能源:鍋爐給水加熱、凝汽器
  • o 制藥食品:發(fā)酵罐控溫、巴氏殺菌
  • o 船舶工程:中央冷卻系統(tǒng)

四、選型需提供的參數(shù)

  • o 1.介質(zhì)特性(成分、相態(tài)、腐蝕性、結(jié)垢傾向)
  • o 2.工藝參數(shù)(流量、入口/出口溫度、壓力)
  • o 3.壓降限制(殼程/管程允許壓降)
  • o 4.清洗要求(是否需要可拆卸設(shè)計)

五、優(yōu)勢

  • o 高壓高溫適應(yīng)性 – 高可承受30 MPa/600°C極端工況。
  • o 長壽命 – 材料耐腐蝕+結(jié)構(gòu)抗疲勞設(shè)計。
  • o 靈活配置 – 支持多流程、多材質(zhì)組合。

六、與其它換熱器的區(qū)別

對比項 殼管式換熱器 板式換熱器 板翅式換熱器
承壓能力 高(≤30 MPa) 中(≤2.5 MPa) 中(≤8 MPa)
適用溫度 -196°C ~ +600°C -50°C ~ +200°C -269°C ~ +200°C
緊湊度 低(體積大) 極高
維護成本 中(可拆卸式較高) 低(板片易清洗) 高(全焊接難維修)
注:殼管式換熱器需根據(jù)工藝需求選擇固定管板(BEM)、浮頭式(AES)或U型管(BEU)等類型。
