2．間壁傳熱式換熱器。冷、熱流體通過(guò)管子、板等壁面進(jìn)行熱量交換的傳熱操作過(guò)程的換熱器,是較普通的也較常用的換熱器,冷、熱流體都是流體,可以是空氣、煙氣、蒸汽、水。 3．蓄熱式換熱器。系間歇傳熱,在廢熱再生器中是切實(shí)可行有效的回收廢熱的方式,常被用于回收燃燒氣體的廢熱以及蒸汽等用量不均時(shí)作為調(diào)節(jié)手段。把板式換熱器的壓緊螺柱卸掉后，汕尾換熱器定制，汕尾換熱器定制，即可松開(kāi)板束，卸下板片，進(jìn)行機(jī)械清洗。汕尾換熱器定制</p><div style="width:100%;text-align:

style="text-indent:25px">板式換熱器的設(shè)計(jì)特點(diǎn) 1、高效節(jié)能：其換熱系數(shù)在3000～4500kcal/m2·°C·h，比管殼式換熱器的熱效率高3~5倍。 2、結(jié)構(gòu)緊湊：板式換熱器板片緊密排列，與其他換熱器類(lèi)型相比，板式換熱器的占地面積和占用空間較少，面積相同換熱量的板式換熱器*為管殼式換熱器的1/5。 3、容易清洗拆裝方便：板式換熱器靠夾緊螺栓將夾固板板片夾緊，因此拆裝方便，隨時(shí)可以打開(kāi)清洗，同時(shí)由于板面光潔，湍流程度高，不易結(jié)垢。 4、使用壽命長(zhǎng)：板式換熱器采用不銹鋼或鈦合金板片壓制，可耐各種腐蝕介質(zhì)，膠墊可隨意更換，并可方便在、拆裝檢修。 5、適應(yīng)性強(qiáng)：板式換熱器板片為**元件，可按要求隨意增減流程，形式多樣；可適用于各種不同的、工藝的要求。 6、不串液，板式換熱器密封槽設(shè)置泄液液道，各種介質(zhì)不會(huì)串通，即使出現(xiàn)泄露，介質(zhì)總是向外排出。深圳換熱器費(fèi)用哪家便宜換熱器的價(jià)格主要由商品附加值決定。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

</p><p style="text-indent:25px">板式換熱器的特點(diǎn)：1、對(duì)數(shù)平均溫差大。2、占地面積小，結(jié)構(gòu)緊湊，清洗方便。3、重量輕，板片的厚度一般在0.4-0.7密碼。4、傳熱系數(shù)高，板片的波紋能使流體在較小的流速下產(chǎn)生湍流。5、可改變換熱面積或流程組合，增加或減少板片數(shù)量即可達(dá)到所需要的換熱面積，改變板片的排港列，可適用于不同的換熱器。換熱器外漏的原因是：①夾緊尺寸不到位、各處尺寸不均勻（各處尺寸偏差不應(yīng)大于3 mm）或夾緊螺栓松動(dòng)。② 部分密封墊脫離密封槽，密封墊主密封面有臟物，密封墊損壞或板式換熱器密封墊片老化。③ 板片發(fā)生變形，組裝錯(cuò)位引起跑墊。④在板片密封槽部位或二道密封區(qū)域有裂紋。實(shí)例：北京、青海和新疆等地的多個(gè)熱力站均采用飽和蒸汽作為一次側(cè)熱源供暖，由于蒸汽溫度較高，在設(shè)備運(yùn)行初期系統(tǒng)不穩(wěn)定的情況下，橡膠密封墊在高溫下失效，引起蒸汽外漏。板式換熱器兩種流體可實(shí)現(xiàn)純逆流，一般為順流或逆流方式。</p><div
