液體的儲(chǔ)存 liquid storage
液體二氧化碳的儲(chǔ)存屬于帶壓（壓力不低于0.8Mpa）儲(chǔ)存。儲(chǔ)存期間除壓力表、液位計(jì)、安全閥應(yīng)投入使用外，其他閥門應(yīng)處于關(guān)閉狀態(tài)。當(dāng)儲(chǔ)罐壓力超過2.1Mpa時(shí)，開啟V7排氣閥降壓。但應(yīng)注意：內(nèi)罐的壓力不得降至低于0.8Mpa，否則將引起液體二氧化碳轉(zhuǎn)變?yōu)楦杀?br>Liquid carbon dioxide storage with pressure (pressure not less than 0.8Mpa) storage. During the storage, the pressure gauge,level gauge, safety valve should be put into use, the other valves should be closed. When the tank pressure exceeds 2.1Mpa, open the V7 exhaust valve buck. However, it should be noted that the pressure inside the tank must not drop below 0.8Mpa, otherwise liquid carbon dioxide will be converted to dry ice.

二氧化碳儲(chǔ)罐的結(jié)構(gòu)和安全特性
夾層封結(jié)后真空度規(guī)范為有效容積：小于等于10m3真空度≤ 2Pa大于10m3小于等于50m3真空度≤3Pa大于50m3小于等于100m3真空度≤
5Pa以精深的技能它作用主要是用來儲(chǔ)存：油田清洗機(jī)，液態(tài)二氧化碳(LCO2功能方面：絕熱資料選用熱態(tài)下的珠光砂充填?yuàn)A層并抽真空。共同的填充技術(shù)，質(zhì)量保證許諾，以達(dá)到的絕熱作用。
為真空粉末絕熱型式低溫液態(tài)二氧化碳儲(chǔ)罐構(gòu)造為表里容器構(gòu)成的雙層容器。可分臥式和立式兩類，內(nèi)容器資料選 16MnDR外容器資料可根據(jù)用戶區(qū)域不一樣選 Q235-B或 16MnR內(nèi)、外容器夾層充填絕熱資料珠光砂并抽真空。
安全閥定時(shí)校驗(yàn)時(shí)可封閉一側(cè)，低溫液體二氧化碳儲(chǔ)罐選用 組合、安全體系閥”運(yùn)用兩組安全閥一起作業(yè)。另一側(cè)持續(xù)作業(yè)，保證儲(chǔ)罐的安全運(yùn)轉(zhuǎn)。

常見故障的處理 Common fault handling

1.內(nèi)罐壓力異常長高 Inner tank pressure abnormally high
1.1可能是V3回氣閥開度過大或閥門失靈，應(yīng)減小閥門開度或檢修閥門。
May be V3 return valve opening is too large or valve failure, should reduce the valve opening or valve repair.
1.2可能是S1、S2安全閥失靈，到啟動(dòng)壓力不啟動(dòng)，應(yīng)檢查安全閥。
may be S1, S2 safety valve failure, to start the pressure does not start, check the safety valve.
1.3可能是壓力表指示不準(zhǔn)確，應(yīng)校驗(yàn)壓力表。
may be pressure gauge indicates inaccurate, should verify the pressure gauge.
2.液位計(jì)指示不真實(shí) Level gauge instructions are not true
2.1可能是液位計(jì)失靈，應(yīng)檢修液位計(jì)。
may be the level gauge failure, should be maintenance level gauge
2.2可能是液位計(jì)接頭處泄漏，應(yīng)檢修接頭連接處，排除泄漏。
It may be a leak at the head of the liquid level gauge. It should repair the connection of the joint and eliminate the leakage
3.蒸發(fā)率高，外殼體凝水結(jié)霜 High evaporation rate, the outer shell condensate frost
3.1可能是珠光砂未填實(shí)或下沉，應(yīng)補(bǔ)充珠光砂，重新抽真空。
may be unfilled or sinking of pearl sand, pearl sand should be added and re-evacuated.
3.2可能是真空度惡化，應(yīng)進(jìn)行真空檢漏，重新抽真空。
may be a deterioration of the vacuum, vacuum leak detection should be carried out, re-vacuum.
4.管道閥門液體流動(dòng)不暢或堵塞 pipeline valve fluid flow or blocked
可能是液體二氧化碳形成干冰的原因造成，應(yīng)停止使用，用熱空氣加溫管閥至?xí)惩橹埂ay be caused by the formation of dry ice, should stop using, with hot air heating pipe valve until smooth.
