style="text-indent:25px">換熱器選用要點(diǎn)：1、根據(jù)已知冷、熱流體的流量，初、終溫度及流體的比熱容決定所需的換熱面積。初步估計(jì)換熱面積，一般先假定傳熱系數(shù)，確定換熱器構(gòu)造，再校核傳熱系數(shù)K值。2、選用換熱器時(shí)應(yīng)注意壓力等級，使用溫度，接口的連接條件。在壓力降，安裝條件允許的前提下，管殼式換熱器以選用直徑小的加長型，有利于提高換熱量。3、換熱器的壓力降不宜過大，一般控制在0.01～0.05MPa之間；4、流速大小應(yīng)考慮流體黏度，黏度大的流速應(yīng)小于0.5～1.0m/s；一般流體管內(nèi)的流速宜取0.4～1.0m/s；易結(jié)垢的流體宜取0.8～1.2m/s。5、高溫水進(jìn)入換熱器前宜設(shè)過濾器。大型換熱器廠家直銷換熱器的折流檔板還迫使流體按規(guī)定路徑多次錯(cuò)流通過管束。</p><div

style="text-indent:25px">由于板式熱交換器流通截面較小，結(jié)垢后容易產(chǎn)生堵塞，使板式熱交換器的換熱效率降低，影響了設(shè)備的安全和用戶的正常用熱。因此，解決板式熱交換器的清洗，防止水垢的形成，將成為確保安全生產(chǎn)和經(jīng)濟(jì)運(yùn)行的重要課題。板式熱交換器結(jié)垢堵塞的主要原因及其危害板式熱交換器在使用過程中，由于水處理設(shè)備運(yùn)行不當(dāng)，水質(zhì)控制不達(dá)標(biāo)，將不合格的軟化水注入供熱系統(tǒng)中，使水中的鈣、鎂、碳酸鹽遇熱后分解為碳酸鈣和氫氧化鎂沉淀物黏結(jié)在換熱器的受熱面上，形成了堅(jiān)硬的水垢。由于水垢的導(dǎo)熱性能差，造成了換熱器換熱效率的降低以及熱能的嚴(yán)重浪費(fèi)，從而影響了供熱的效果，給供熱單位造成了嚴(yán)重的負(fù)面影響。</p><p style="text-indent:25px">扁管換熱器，通常稱為麻花管換熱器。螺旋扁管的制造過程包括了“壓扁”與“熱扭”兩個(gè)工序。改進(jìn)后的麻花管換熱器同傳統(tǒng)的管殼式換熱器一樣簡單，但有許多激動(dòng)人心的進(jìn)步，它獲得了如下的技術(shù)經(jīng)濟(jì)效益：改進(jìn)了傳熱，減少了結(jié)垢，真正的逆流，降低了成本，無振動(dòng)，節(jié)省了空間，無折流元件。由于管子結(jié)構(gòu)獨(dú)特使管程與殼程同時(shí)處于螺旋運(yùn)動(dòng)，促進(jìn)了湍流程度。該換熱器總傳熱系數(shù)較常規(guī)換熱器高40%，而壓力降幾乎相等。組裝換熱器時(shí)也可采用螺旋扁管與光管混合方式。該換熱器嚴(yán)格按照標(biāo)準(zhǔn)制造。凡是用管殼式換熱器和傳統(tǒng)裝置之處均可用此種換熱器取代。它能獲得普通管殼式換熱器和板框式傳熱設(shè)備所獲得的比較好值。估計(jì)在化工、石油化工行業(yè)中具有廣闊的應(yīng)用前景。換熱器為提高傳熱系數(shù)，容器內(nèi)可安裝攪拌器。</p><div

style="text-indent:25px">換熱器是一種在不同溫度的兩種或兩種以上流體間實(shí)現(xiàn)物料之間熱量傳遞的節(jié)能設(shè)備，是使熱量由溫度較高的流體傳遞給溫度較低的流體，使流體溫度達(dá)到流程規(guī)定的指標(biāo)，以滿足工藝條件的需要，同時(shí)也是提高能源利用率的主要設(shè)備之一。換熱器行業(yè)涉及暖通、壓力容器、中水處理設(shè)備，化工，石油等近30多種產(chǎn)業(yè)，相互形成產(chǎn)業(yè)鏈條。數(shù)據(jù)顯示2010年中國換熱器產(chǎn)業(yè)市場規(guī)模在500億元左右，主要集中于石油、化工、冶金、電力、船舶、集中供暖、制冷空調(diào)、機(jī)械、食品、制藥等領(lǐng)域。換熱器在化工、石油、動(dòng)力、食品及其它許多工業(yè)生產(chǎn)中占有重要地位。廣州換熱器品牌有哪些</p><p

style="text-indent:25px">板式熱交換器結(jié)垢的清洗方式：清洗劑的選擇，目前采用的是酸洗，它包括有機(jī)酸和無機(jī)酸。有機(jī)酸主要有：草酸、甲酸等。無機(jī)酸主要有：鹽酸、硝酸等。根據(jù)換熱器結(jié)垢和工藝、材質(zhì)和水垢成分分析得出：換熱器流通面積小，內(nèi)部結(jié)構(gòu)復(fù)雜，清洗液若產(chǎn)生沉淀不易排放。換熱器材質(zhì)為鎳鈦合金，使用鹽酸為清洗液，容易對板片產(chǎn)生強(qiáng)腐蝕，縮短換熱器的使用壽命。通過反復(fù)試驗(yàn)發(fā)現(xiàn)，選擇甲酸作為清洗液效果較好。在甲酸清洗液中加入緩沖劑和表面活性劑，清洗效果更好，并可降低清洗液對板片的腐蝕。河南換熱器價(jià)格</p></p><br
