一、儲罐檢測的周期
儲(chu)(chu)罐(guan)(guan)屬于(yu)特種(zhong)設備,需(xu)(xu)要定期進行(xing)檢(jian)(jian)(jian)驗(yan)檢(jian)(jian)(jian)測,以免(mian)留下(xia)安全(quan)隱患,儲(chu)(chu)罐(guan)(guan)的(de)(de)(de)檢(jian)(jian)(jian)驗(yan)分為(wei)外(wai)部檢(jian)(jian)(jian)驗(yan)和(he)(he)內(nei)(nei)部檢(jian)(jian)(jian)驗(yan),外(wai)部檢(jian)(jian)(jian)驗(yan)是指罐(guan)(guan)內(nei)(nei)貯存有(you)介質(zhi)的(de)(de)(de)情況(kuang)(kuang)下(xia),對(dui)罐(guan)(guan)的(de)(de)(de)各(ge)個部位部件(jian)進行(xing)檢(jian)(jian)(jian)驗(yan),包括目視檢(jian)(jian)(jian)驗(yan)、聲發射檢(jian)(jian)(jian)驗(yan)、沉降(jiang)觀(guan)測等;內(nei)(nei)部檢(jian)(jian)(jian)驗(yan)為(wei)罐(guan)(guan)內(nei)(nei)的(de)(de)(de)介質(zhi)清空之后,對(dui)罐(guan)(guan)的(de)(de)(de)各(ge)個部位部件(jian)進行(xing)檢(jian)(jian)(jian)驗(yan),包括底板背面腐(fu)蝕(shi)狀況(kuang)(kuang)檢(jian)(jian)(jian)測、焊縫無損檢(jian)(jian)(jian)測、真空箱檢(jian)(jian)(jian)測等。儲(chu)(chu)罐(guan)(guan)的(de)(de)(de)檢(jian)(jian)(jian)測周(zhou)(zhou)期需(xu)(xu)要根據儲(chu)(chu)罐(guan)(guan)的(de)(de)(de)技(ji)術使(shi)用條件(jian)來確定和(he)(he)計算,一(yi)般正常情況(kuang)(kuang)下(xia),檢(jian)(jian)(jian)測周(zhou)(zhou)期為(wei):外(wai)部檢(jian)(jian)(jian)查(cha)每年(nian)至少一(yi)次(ci),內(nei)(nei)部檢(jian)(jian)(jian)查(cha)每3年(nian)至少一(yi)次(ci),全(quan)面檢(jian)(jian)(jian)查(cha)每6年(nian)至少一(yi)次(ci)。若(ruo)(ruo)儲(chu)(chu)罐(guan)(guan)使(shi)用年(nian)限(xian)達到15年(nian)以上,則(ze)每兩年(nian)則(ze)需(xu)(xu)進行(xing)一(yi)次(ci)內(nei)(nei)外(wai)部檢(jian)(jian)(jian)驗(yan),若(ruo)(ruo)使(shi)用年(nian)限(xian)達20年(nian),則(ze)每一(yi)年(nian)至少進行(xing)一(yi)次(ci)內(nei)(nei)外(wai)部檢(jian)(jian)(jian)查(cha)。
二、儲罐呼吸閥工作原理
儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)呼(hu)(hu)吸(xi)(xi)閥是安(an)裝在儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)頂上(shang)(shang)的(de)部(bu)(bu)件,主要用來滿足(zu)儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)大小呼(hu)(hu)吸(xi)(xi)的(de)通(tong)氣要求(qiu),一般(ban)(ban)由(you)壓力(li)閥和(he)真空閥兩部(bu)(bu)分組(zu)成(cheng),它的(de)作用是在一般(ban)(ban)情(qing)況下,保持儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)的(de)密閉性(xing),在一定(ding)程(cheng)度上(shang)(shang)減(jian)少儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)內(nei)儲(chu)(chu)(chu)(chu)存物質(zhi)的(de)蒸發損(sun)耗;在必要時(shi),它又能自(zi)動通(tong)氣,調節平衡儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)內(nei)外(wai)(wai)壓力(li),對(dui)儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)起到安(an)全(quan)作用,其工(gong)作原理是:當罐(guan)(guan)(guan)(guan)(guan)內(nei)介質(zhi)的(de)壓力(li)在呼(hu)(hu)吸(xi)(xi)閥的(de)控制操(cao)作壓力(li)范圍之內(nei)時(shi),呼(hu)(hu)吸(xi)(xi)閥不工(gong)作,保持儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)的(de)密封(feng)性(xing);當往(wang)罐(guan)(guan)(guan)(guan)(guan)內(nei)補(bu)充(chong)介質(zhi),使罐(guan)(guan)(guan)(guan)(guan)內(nei)上(shang)(shang)部(bu)(bu)氣體(ti)空間的(de)壓力(li)升高(gao),達(da)到呼(hu)(hu)吸(xi)(xi)閥的(de)操(cao)作正壓時(shi),壓力(li)閥被頂開(kai),氣體(ti)從呼(hu)(hu)吸(xi)(xi)閥呼(hu)(hu)出口逸出,使罐(guan)(guan)(guan)(guan)(guan)內(nei)壓力(li)不在繼續增高(gao);罐(guan)(guan)(guan)(guan)(guan)外(wai)(wai)的(de)大氣將頂開(kai)呼(hu)(hu)吸(xi)(xi)閥的(de)負壓閥盤,將儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)中的(de)空間和(he)大氣進行隔絕,從而(er)保護儲(chu)(chu)(chu)(chu)罐(guan)(guan)(guan)(guan)(guan)的(de)安(an)全(quan)。
三、儲罐類型有哪些
儲罐的種類眾多,按照不同的分類方法可分為不同類型:1、按位置歸類:可分成地上儲罐、海上儲罐、半地下儲罐、地下儲罐、海底儲罐等。2、按油品歸類:可分成原油儲罐、食用油罐、潤滑油罐、燃油儲罐、消防水罐等。3、按用途歸類:可分成原料罐、成品罐、中間產品罐、廢料罐等。4、按方式歸類:可分成立式儲罐、球形儲罐、雙曲線儲罐(滴形儲罐)、臥式儲罐、懸鏈式儲罐(無力矩儲罐)等。5、按溫度歸類:常溫儲罐、低溫儲罐、高溫儲罐。6、按壓力歸類:常壓儲罐、低壓儲罐、高壓儲罐。7、按儲罐材料歸類:聚乙烯儲罐、橡膠儲罐、玻璃鋼儲罐、陶瓷儲罐、聚丙烯儲罐、不銹鋼儲罐等。8、按容量歸類: 50m3以上為大型儲罐,多為立式儲罐;50m3以下的為小型儲罐。如果您需要購買儲罐,可以先來了解一下儲罐十大品牌。
四、貯罐和儲罐的區別
貯(zhu)(zhu)罐(guan),讀作zhù guàn,是(shi)(shi)貯(zhu)(zhu)存各(ge)種(zhong)液體(ti)原料(liao)、半成(cheng)(cheng)品或成(cheng)(cheng)品的設備(bei),它(ta)和儲(chu)罐(guan)實際上并沒有什么(me)區別(bie),是(shi)(shi)同(tong)一(yi)物體(ti)的兩(liang)個不同(tong)稱呼。從字面意(yi)思(si)上來看,貯(zhu)(zhu)是(shi)(shi)儲(chu)存的意(yi)思(si),如貯(zhu)(zhu)存、貯(zhu)(zhu)藏、貯(zhu)(zhu)積;儲(chu)是(shi)(shi)積蓄的意(yi)思(si),如儲(chu)蓄、儲(chu)備(bei)、儲(chu)金、儲(chu)放(fang)、儲(chu)運(yun),它(ta)們都有存放(fang)的意(yi)思(si);通過(guo)查詢定義也(ye)發現(xian)二(er)者是(shi)(shi)差(cha)不多的,貯(zhu)(zhu)罐(guan)指用于貯(zhu)(zhu)存各(ge)種(zhong)液體(ti)原料(liao)、半成(cheng)(cheng)品或成(cheng)(cheng)品的設備(bei),儲(chu)罐(guan)是(shi)(shi)用以存放(fang)酸、醇、氣體(ti)等提煉的化(hua)學物質的設備(bei)。因此,綜上所述,貯(zhu)(zhu)罐(guan)和儲(chu)罐(guan)實際上是(shi)(shi)同(tong)一(yi)種(zhong)物體(ti)的兩(liang)個不同(tong)稱呼,二(er)者實際上并沒有什么(me)區別(bie),用儲(chu)罐(guan)或貯(zhu)(zhu)罐(guan)都可以。
