株洲二氧化碳储罐

液体的储存 liquid storage
液体二氧化碳的储存属于带压（压力不低于0.8Mpa）储存。储存期间除压力表、液位计、安全阀应投入使用外，其他阀门应处于关闭状态。当储罐压力超过2.1Mpa时，开启V7排气阀降压。但应注意：内罐的压力不得降至低于0.8Mpa，否则将引起液体二氧化碳转变为干冰。
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.

二氧化碳储罐的结构和安全特性
夹层封结后真空度规范为有效容积：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来储存：油田清洗机，液态二氧化碳(LCO2功能方面：绝热资料选用热态下的珠光砂充填夹层并抽真空。共同的填充技术，质量保证许诺，以达到的绝热作用。
为真空粉末绝热型式低温液态二氧化碳储罐构造为表里容器构成的双层容器。可分卧式和立式两类，内容器资料选 16MnDR外容器资料可根据用户区域不一样选 Q235-B或 16MnR内、外容器夹层充填绝热资料珠光砂并抽真空。
安全阀定时校验时可封闭一侧，低温液体二氧化碳储罐选用 组合、安全体系阀”运用两组安全阀一起作业。另一侧持续作业，保证储罐的安全运转。

常见故障的处理 Common fault handling
【产品详情图片】
1.内罐压力异常长高 Inner tank pressure abnormally high
1.1可能是V3回气阀开度过大或阀门失灵，应减小阀门开度或检修阀门。
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安全阀失灵，到启动压力不启动，应检查安全阀。
may be S1, S2 safety valve failure, to start the pressure does not start, check the safety valve.
1.3可能是压力表指示不准确，应校验压力表。
may be pressure gauge indicates inaccurate, should verify the pressure gauge.
2.液位计指示不真实 Level gauge instructions are not true
2.1可能是液位计失灵，应检修液位计。
may be the level gauge failure, should be maintenance level gauge
2.2可能是液位计接头处泄漏，应检修接头连接处，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.蒸发率高，外壳体凝水结霜 High evaporation rate, the outer shell condensate frost
3.1可能是珠光砂未填实或下沉，应补充珠光砂，重新抽真空。
may be unfilled or sinking of pearl sand, pearl sand should be added and re-evacuated.
3.2可能是真空度恶化，应进行真空检漏，重新抽真空。
may be a deterioration of the vacuum, vacuum leak detection should be carried out, re-vacuum.
4.管道阀门液体流动不畅或堵塞 pipeline valve fluid flow or blocked
可能是液体二氧化碳形成干冰的原因造成，应停止使用，用热空气加温管阀至畅通为止。May be caused by the formation of dry ice, should stop using, with hot air heating pipe valve until smooth.
