style="text-indent:25px">目前我國(guó)使用范圍較普遍、制作安裝技術(shù)較成熟的是拱頂儲(chǔ)罐、浮頂儲(chǔ)罐和臥式儲(chǔ)罐。拱頂儲(chǔ)罐是指罐頂為球冠狀、罐體為圓柱形的一種鋼制容器。拱頂儲(chǔ)罐制造簡(jiǎn)單、造價(jià)低廉，所以在國(guó)內(nèi)外許多行業(yè)應(yīng)用較為普遍，較常用的容積為 1000 -10000m 3 ，國(guó)內(nèi)拱頂儲(chǔ)罐的較大容積已經(jīng)達(dá)到 30000m 3 。罐底：罐底由鋼板拼裝而成，罐底中部的鋼板為中幅板，周邊的鋼板為邊緣板。邊緣板可采用條形板，也可采用弓形板。一般情況下，儲(chǔ)罐內(nèi)徑< 16.5m 時(shí)，宜采用條形邊緣板，儲(chǔ)罐內(nèi)徑≥ 16.5m 時(shí)，宜采用弓形邊緣板。罐壁：罐壁由多圈鋼板組對(duì)焊接而成，分為套筒式和直線式。套筒式罐壁板環(huán)向焊縫采用搭接，縱向焊縫為對(duì)接。拱頂儲(chǔ)罐多采用該形式，其優(yōu)點(diǎn)是便于各圈壁板組對(duì)，采用倒裝法施工比較安全。直線式罐壁板環(huán)向焊縫為對(duì)接。優(yōu)點(diǎn)是罐壁整體自上而下直徑相同，特別適用于內(nèi)浮頂儲(chǔ)罐，但組對(duì)安裝要求較高、難度亦較大。罐頂：罐頂有多塊扇形板組對(duì)焊接而成球冠狀，罐頂內(nèi)側(cè)采用扁鋼制成加強(qiáng)筋，各個(gè)扇形板之間采用搭接焊縫，整個(gè)罐頂與罐壁板上部的角鋼圈（或稱鎖口）焊接成一體。浙江化工立式儲(chǔ)罐化工儲(chǔ)罐材料具有良好的防腐蝕性能。</p><div

style="text-indent:25px">儲(chǔ)罐一般位于石油化工、鋼鐵工業(yè)等區(qū)域，空氣中的酸性氣體在雨水中溶解或夏季用于冷卻的噴水中溶解，導(dǎo)致鋼質(zhì)表面液膜下的氧去極化反應(yīng)。當(dāng)溫度周期性下降時(shí)，溶解在電解液中的水會(huì)凝結(jié)儲(chǔ)罐外表面，形成連續(xù)的電解質(zhì)溶液膜層，從而引起腐蝕。儲(chǔ)罐外壁的一種腐蝕主要是底板外壁的大氣電化學(xué)腐蝕。這主要是由于大氣中水、氧、溫差的變化，沿海鹽霧、化學(xué)氣氛等腐蝕性氣體的腐蝕，以及紫外線對(duì)涂層的老化破壞所致。儲(chǔ)罐防腐除銹有儲(chǔ)罐內(nèi)壁防腐除銹，也有儲(chǔ)罐外壁防腐除銹，一般來(lái)講儲(chǔ)罐外壁防腐除銹要比內(nèi)壁防腐除銹簡(jiǎn)單的多，因?yàn)楣摅w（各種罐體）內(nèi)部因有部分殘留油氣，特別是有些油氣的極限不高時(shí)很容易引發(fā)安全事故，所以內(nèi)壁防腐防爆級(jí)別高于油罐外壁防腐。</p><p

style="text-indent:25px">傳統(tǒng)的儲(chǔ)罐加熱方式是這樣的：采用罐內(nèi)安裝列管式或盤管式加熱器，使罐內(nèi)粘稠液體通過(guò)與熱媒體（一般以飽和蒸汽為熱媒體）的交換，實(shí)現(xiàn)對(duì)粘稠液體的升溫，降低液體粘度，改善其流動(dòng)性，以便于泵的輸送。傳統(tǒng)儲(chǔ)罐加熱方式使用的很多年，不免越來(lái)越顯現(xiàn)它的弊端： 1、換熱效率低，蒸汽耗量大。傳統(tǒng)罐內(nèi)加熱器對(duì)粘稠液體的加熱是一種靜置式的自然對(duì)流換熱，其放熱系數(shù)極低。由于換熱效率低，泠凝水溫度高，常常隨著大量蒸汽排除。同時(shí)由于在加熱管表面的粘稠液體溫度過(guò)高，在換熱管高溫面長(zhǎng)時(shí)間滯留，極容易產(chǎn)生分解物，結(jié)聚于換熱管表面，容易結(jié)焦，嚴(yán)重阻礙熱量的傳遞，也影響換熱效率。 2、加熱過(guò)程不經(jīng)濟(jì)。當(dāng)只需要倒出少量粘稠液體時(shí)，也要對(duì)整個(gè)罐內(nèi)的粘稠液體全部進(jìn)行加熱，加熱的數(shù)量是該次使用量的幾倍，使大量的蒸汽做了無(wú)用功。 3、罐內(nèi)各部分粘稠液體溫度不均衡。靠近加熱器的粘稠液體溫度較高，遠(yuǎn)離加熱器的粘稠液體溫度較低，抽取粘稠液體的溫度更低，嚴(yán)重影響了出油的流動(dòng)性。 4、影響粘稠液體質(zhì)量。反復(fù)對(duì)罐內(nèi)粘稠液體進(jìn)行加熱，加熱過(guò)程中產(chǎn)生大量細(xì)小的分解物，對(duì)粘稠液體質(zhì)量產(chǎn)生一定的影響，增加了后期處理的成本。儲(chǔ)存液體或氣體的鋼制密封容器即為鋼制儲(chǔ)罐。浙江化工立式儲(chǔ)罐</p><p

style="text-indent:25px">腐蝕是發(fā)生泄漏的重要因素之一。國(guó)內(nèi)外曾發(fā)生多起因油罐底部腐蝕造成的漏油事故。對(duì)原油儲(chǔ)罐內(nèi)腐蝕情況初步調(diào)查的結(jié)果表明，罐底腐蝕情況嚴(yán)重，大多為潰瘍狀的坑點(diǎn)腐蝕 , 主要發(fā)生在焊接熱影響區(qū)、凹陷及變形處，罐頂腐蝕次之，為伴有孔蝕的不均勻各方面腐蝕，罐壁腐蝕較輕，為均勻點(diǎn)蝕，主要發(fā)生在油水界面，油與空氣界面處。相對(duì)而言，儲(chǔ)罐底部的外腐蝕更為嚴(yán)重，主要發(fā)生在邊緣板與環(huán)梁基礎(chǔ)接觸的一面。浮盤沉底事故是浮頂油罐生產(chǎn)作業(yè)時(shí)非常忌諱的嚴(yán)重惡性設(shè)備事故之一。該類事故的發(fā)生，一方面反映了設(shè)計(jì)、施工、管理等方面的嚴(yán)重缺陷，另一方面又將造成大量原油泄漏，嚴(yán)重影響生產(chǎn)、污染環(huán)境并構(gòu)成火災(zāi)隱患。好用的化工立式儲(chǔ)罐</p></p><br
