基于石油、化工、電力、冶金、船舶、機(jī)械、食品、制藥等行業(yè)對(duì)換熱器穩(wěn)定的需求增長，我國換熱器行業(yè)在未來一段時(shí)期內(nèi)將保持穩(wěn)定增長，2011年至2020年期間，我國換熱器產(chǎn)業(yè)將保持年均10-15%左右的速度增長，到2020年我國換熱器行業(yè)規(guī)模有望達(dá)到1500億元[3]。折疊編輯本段類別劃分適用于不同介質(zhì)、不同工況、不同溫度、不同壓力的換熱器，結(jié)構(gòu)型式也不同，換熱器的具體分類如下：一、按傳熱原理分類1、間壁式換熱器間壁式換熱器是溫度不同的兩種流體在被壁面分開的空間里流動(dòng)，通過壁面的導(dǎo)熱和流體在壁表面對(duì)流，兩種流體之間進(jìn)行換熱。間壁式換熱器有管殼式、套管式和其他型式的換熱器。間壁式換熱器是目前應(yīng)用**為***的換熱器。2、蓄熱式換熱器蓄熱式換熱器通過固體物質(zhì)構(gòu)成的蓄熱體，把熱量從高溫流體傳遞給低溫流體，熱介質(zhì)先通過加熱固體物質(zhì)達(dá)到一定溫度后，冷介質(zhì)再通過固體物質(zhì)被加熱，使之達(dá)到熱量傳遞的目的。蓄熱式換熱器有旋轉(zhuǎn)式、閥門切換式等。3、流體連接間接式換熱器流體連接間接式換熱器，是把兩個(gè)表面式換熱器由在其中循環(huán)的熱載體連接起來的換熱器，熱載體在高溫流體換熱器和低溫流體之間循環(huán)，在高溫流體接受熱量。</p><p> 上海板換板式換熱器用途：一直致力于熱交換領(lǐng)域的解決方案，多年來不斷優(yōu)化板式換熱器的應(yīng)用性能和工藝流程，目前已服務(wù)于冶金、鋼鐵、暖通、化工、船舶、食品、石油等不同的工況，在熱交換領(lǐng)域占有重要位置。公司現(xiàn)有16大系列、20余品種的熱交換設(shè)備，主要產(chǎn)品包括可拆卸板式熱交換器、寬通道全焊接板式熱交換器、煙氣冷凝器、板式空氣預(yù)熱器、T&P混合板式換熱器、板框式熱交換器等。公司擁有發(fā)明、實(shí)用新型專利及著作權(quán)等三十余項(xiàng)，技術(shù)人員占公司員工總數(shù)40%以上。公司是首批獲得板式熱交換器產(chǎn)品節(jié)能注冊(cè)證的企業(yè)，也是《板式換熱器行業(yè)標(biāo)準(zhǔn)》起草單位之一，擁有安全注冊(cè)證、特種設(shè)備制造許可（壓力容器）、ASME、<span>S、CE、BV、ABS、GL、NK等證書，獲得中檢協(xié)頒發(fā)的企業(yè)證書，連續(xù)兩年獲得“中國年度板式換熱器**品牌”稱號(hào)，并成為中國城鎮(zhèn)供熱協(xié)會(huì)、中國有色金屬協(xié)會(huì)、中國華電電廠級(jí)會(huì)員等會(huì)員。板式換熱器產(chǎn)品介紹。</p><div

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；可適用于各種不同工藝的要求。6)不串液，板式換熱器密封槽設(shè)置泄液道，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。3鈦制板式換熱器產(chǎn)品系列鈦制板式換熱器主要有汽-液型鈦板冷凝器和液-液型鈦板換熱器2類。各種型號(hào)換熱器有相應(yīng)的產(chǎn)品規(guī)格系數(shù)，依其技術(shù)性能可供選擇。這標(biāo)志著我國已擁有較強(qiáng)的鈦制板式換熱器設(shè)備的設(shè)計(jì)、制造能力[1]。4鈦制板式換熱器在海水淡化中的應(yīng)用淡水約占地球水資源的3%，通過海水淡化獲取新的淡水資源是今后世界用水的一大趨勢(shì)。在解決沿海地區(qū)淡水資源緊張的諸多方法當(dāng)中，海水淡化是一種切實(shí)可行且有效的辦法。其中多級(jí)閃蒸(Muiti-StageFl，縮寫為MSF)海水淡化技術(shù)占有主導(dǎo)地位。其生產(chǎn)能力為全世界海水淡化總產(chǎn)量的56%。世界上規(guī)模在4000t/d以上的海水淡化裝置中，MSF裝置占。目前，單機(jī)容量比較大的MSF裝置是意大利SIR/EU-TECO公司生產(chǎn)的，出力為36000t/d，安裝在意大利本土[2]。海水淡化技術(shù)在我國還處于起步階段，目前*有少量的小型反滲透裝置，而大容量蒸餾裝置(包括多級(jí)閃蒸MSF、多效蒸發(fā)ME、蒸汽壓縮蒸餾VC等)的開發(fā)生產(chǎn)才剛剛開始。板式換熱器可以應(yīng)用于各個(gè)行業(yè)。湖南供暖換熱器電話</p><p

固定管板式換熱器的兩端應(yīng)留出足夠的空間以便能抽出和更換管子。并且，用機(jī)械法清洗管內(nèi)時(shí)。兩端都可以對(duì)管子進(jìn)行刷洗操作。U形管式換熱器的固定頭蓋應(yīng)留出足夠的空間以便抽出管束，也可在其相對(duì)的一端留出足夠的空間以便能拆卸殼體。換熱器不得在超過銘牌規(guī)定的條件下運(yùn)行。應(yīng)經(jīng)常對(duì)管，殼程介質(zhì)的溫度及壓降進(jìn)行監(jiān)督，分析換熱管的泄漏和結(jié)垢情況。管殼式換熱器就是利用管子使其內(nèi)外的物料進(jìn)行熱交換、冷卻、冷凝、加熱及蒸發(fā)等過程，與其他設(shè)備相比較，其余腐蝕介質(zhì)接觸的表面積就顯得非常大，發(fā)生腐蝕穿孔結(jié)合處松弛泄漏的危險(xiǎn)性很高，因此對(duì)換熱器的防腐蝕和防泄漏的方法也比其他設(shè)備要多加考慮，當(dāng)換熱器用蒸汽來加熱或用水來冷卻時(shí)，水中的溶解物在加熱后，大部分溶解度都會(huì)有所提高，而***鈣類型的物質(zhì)則幾乎沒有變化。冷卻水經(jīng)常循環(huán)使用，由于水的蒸發(fā)，使鹽類濃縮，產(chǎn)生沉積或污垢。又因水中含有腐蝕性溶解氣體及氯離子等引起設(shè)備腐蝕，腐蝕與結(jié)垢交替進(jìn)行，激化了鋼材的腐蝕。因此必須經(jīng)過清洗來改善換熱器的性能。由于清洗的困難程度是隨著垢層厚度或沉積的增加而迅速增大的，所以清洗間隔時(shí)間不宜過長，應(yīng)根據(jù)生產(chǎn)裝置的特點(diǎn)，換熱介質(zhì)的性質(zhì)。河南傳熱系數(shù)高換熱器電話</p></p><br
