低溫儲罐是我公司七大事業(yè)中心之一---深冷容器事業(yè)中心主要產(chǎn)品，具有有5-200立方米立、臥式低溫液體儲罐（液化天然氣儲罐LNFG，液氧儲罐LO2，液氮儲罐LN2，液氬儲罐LAr2，二氧化碳儲罐LCO2）。
低溫儲罐是貯存低溫液化天然氣、液氧、液氮、液氬、液態(tài)二氧化碳等介質(zhì)的貯存壓力容器。低溫儲罐為雙層固定真空粉末絕熱儲罐（貯槽）。液化天然氣、液氧、液氮、液氬內(nèi)膽原料選用不銹鋼，二氧化碳儲罐為16MnDR），外膽原料為Q345R或許16MnR。外表防腐涂層選用噴砂除銹、吹掃、噴涂等工藝，同時選用了挪威進口佐敦涂料，保證5年油漆不脫落。

低溫儲罐在內(nèi)容器與外容器之間的夾層選用熱態(tài)下的珠光砂為絕熱材料并抽真空，以到達的絕熱作用。
低溫儲罐產(chǎn)品主要用于液化天然氣、液氧、液氮、液氬以及二氧化碳等氣體的低溫液態(tài)存儲。1立方米液體能夠代替130支氣體鋼瓶。它能夠替代每天用氣瓶往返運輸，節(jié)約很多的人力物力。

維護與檢修 Maintenance and repair
【產(chǎn)品詳情圖片】
1.儲罐的使用與維護，應(yīng)按“壓力容器安全技術(shù)監(jiān)察規(guī)程”要求和本說明進行。
The use and maintenance of the storage tank shall be carried out according to the requirements of the Pressure Vessel Safety Technical Supervision Regulations and these instructions
2.日常檢查與維護 Daily inspection and maintenance
儲罐在運行過程中，要經(jīng)常檢查安全閥、壓力表、液位計工作是否正常，閥門管路是否有泄漏，外部有無異?，F(xiàn)象，發(fā)現(xiàn)問題及時處理。
During operation of the tank, check the safety valve, pressure gauge and liquid level meter regularly, whether the valve line is leaking, whether there is any abnormal phenomenon outside, and find the problem to be handled in time.
3.定期校驗 Regular verification
3.1安全閥整定壓力不大于2.27Mpa，每年至少校驗一次，并加鉛封，作好記錄。
Safety valve setting pressure is not more than 2.27Mpa, at least once a year, and add seals, make a record.
3.2定期檢查夾層真空度，未裝低溫介質(zhì)的情況下真空度應(yīng)低于65Pa，裝有低溫介質(zhì)的情況下，真空度應(yīng)低于10Pa為合格。
Regularly check the sandwich vacuum, the vacuum should be less then 65Pa without vacuum medium; with a low temperature medium, the vacuum should be less than 10Pa for the pass.

結(jié)構(gòu)說明 Structure Description
1. 泄放裝置 Discharge device
2. 內(nèi)膽 Liner
3.保溫層(珠光砂) Insulation (pear sand)
4.外殼 Shell
5.儀表(差壓計、氧壓表、組合閥) Meter (differential pressure gauge, oxygen pressure gauge, combination valve)

說 明Description:
⑴本儲罐的操作系統(tǒng)多集中于儲罐底部，儀表系統(tǒng)及組合閥設(shè)置在筒壁，便于觀察操作.
The operating system of the tank and more concentrated in the bottom of the tank, instrument system and valve combination set in the cylinder wall, easy to observe the operation.
(2) 內(nèi)膽設(shè)置有兩個安全閥S1、S2，夾層泄壓裝置B。
There are two safety valves S1, S2 inside the liner, sandwich pressure relief device B.
(3) 連接形式：進液口→2＂螺紋連接，排液閥→2＂螺紋連接，抽空口→法蘭.
Connection: inlet → 2 "thread connection, drain valve → 2" thread connection, exhaust port → flange.

液體的儲存 liquid storage
液體二氧化碳的儲存屬于帶壓（壓力不低于0.8Mpa）儲存。儲存期間除壓力表、液位計、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)儲罐壓力超過2.1Mpa時，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.
