2、如果用污水作冷卻介質(zhì)，或回收污水的余熱，或介質(zhì)內(nèi)含有粒狀固體物時，要在換熱器入口端裝上過濾器或除污器，以免堵塞換熱器，深圳容積式換熱器工廠。 3、冷卻水（被加熱）溫度超過40℃時，應(yīng)盡可能先進行軟化處理，以免換熱器結(jié)垢，影響傳熱效果。 4、檢查管線連接是否正確，避免兩種介質(zhì)相混，引起不良后果。 5、開車前嚴格檢查冷、熱介質(zhì)的進口閥門是否關(guān)閉，深圳容積式換熱器工廠，出口閥門是否開啟。 6、完成上述工作后可開機。開車先啟動冷、熱介質(zhì)的泵，慢慢地打開冷介質(zhì)的進口閥，然后打開熱介質(zhì)的進口閥，深圳容積式換熱器工廠，使介質(zhì)緩慢地流入換熱器，以免溫度過高。 7、檢查所有密封面及所有焊縫處有無滲漏等不正常的現(xiàn)象。 8、緩慢地升溫，同時測定和計算是否滿足工藝要求。滿足后即可進入正常操作。使用換熱器注意事項:開機前應(yīng)先檢查整個管路聯(lián)接系統(tǒng)以及所要求的流體進出口聯(lián)接形式。深圳容積式換熱器工廠</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

style="text-indent:25px">換熱器在使用中應(yīng)注意哪些事項？（1）換熱器在新安裝或檢修完工之后必須進行試壓合格后才能使用。（2）換熱器在開工時要先通冷流后通熱流，在停工時要先停熱流后停冷流。（3）啟用過程中，冷卻水排氣閥應(yīng)保持打開狀態(tài)，以便排出全部空氣，啟用結(jié)束后應(yīng)關(guān)閉。換熱器（，是將熱流體的部分熱量傳遞給冷流體的設(shè)備，又稱熱交換器。換熱器在化工、石油、動力、食品及其它許多工業(yè)生產(chǎn)中占有重要地位，其在化工生產(chǎn)中換熱器可作為加熱器、冷卻器、冷凝器、蒸發(fā)器和再沸器等，應(yīng)用普遍。</p><p style="text-indent:25px">板式換熱器清洗水垢的工藝要求:1)酸洗溫度：提升酸洗溫度有利于提高除垢效果．如果溫度過高就會加劇酸洗液對換熱器板片的腐蝕，通過反復(fù)試驗發(fā)現(xiàn)，酸洗溫度控制在60~E為宜。 2)酸洗液濃度：根據(jù)反復(fù)試驗得出，酸洗液應(yīng)按甲酸81．O％、水17．O％、緩沖劑1．2％、表面活性劑0．8％的濃度配制，清洗效果很好。3)酸洗方法及時間：酸洗方法應(yīng)以靜態(tài)浸泡和動態(tài)循環(huán)相結(jié)合的方法進行。酸洗時間為先靜態(tài)浸泡2 h，然后動態(tài)循環(huán)3～4 h。在酸洗過程中應(yīng)經(jīng)常取樣化驗酸洗濃度，當相鄰兩次化驗濃度差值低于0．2％時，即可認為酸洗反應(yīng)結(jié)束。4)鈍化處理：酸洗結(jié)束后，板式換熱器表面的水垢和金屬氧化物絕大部分被溶解脫落，暴露出嶄新的金屬，極易腐蝕，因此在酸洗后，對換熱器板片進行鈍化處理。換熱器是熱量由溫度較高的流體傳遞給溫度較低的流體，使流體溫度達到流程規(guī)定的指標。</p><div

style="text-indent:25px">換熱器選型需要考慮的因素：1.根據(jù)工藝介質(zhì)的換熱要求及所建裝置的水源、電力情況，進行換熱器技術(shù)經(jīng)濟比較，以確定使用風冷卻器的合理性；2.根據(jù)熱介質(zhì)要求的冷卻終溫、環(huán)境條件，確定換熱器的型式；3.按經(jīng)驗總傳熱系數(shù)初步估算所需的換熱面積，選擇風冷卻器型號；4.根據(jù)工藝介質(zhì)的操作條件及物性，對初選型號進行精確核算：管內(nèi)膜傳熱系數(shù)及阻力降、管外傳熱系數(shù)及阻力降、總傳熱系數(shù)、有效平均溫差，進而計算所需傳熱面積。 5.根據(jù)裝置生產(chǎn)特點，綜合考慮換熱器的安裝布置、使用方式等方面。6.還有使用時的噪音、振動、腐蝕、維護等各方面綜合考慮。板水加熱器的主要控制參數(shù)為水加熱器的單板換熱面積、總換熱面積、設(shè)計壓力、工作壓力、熱媒參數(shù)等。深圳容積式換熱器工廠</p><p
