大庆二氧化碳储罐

二氧化碳储罐材料
绝热性能
绝热材料选用热态下的珠光砂充填夹层并抽真空，夹层封结后真空度标准为：
有效容积：小于等于 10m 3 真空度≤ 2Pa ，大于 10m 3 小于等于 50m 3真空度≤ 3Pa ，大于 50m 3 小于等于 100m 3 真空度≤ 5Pa ，以精湛的技术，独特的填充工艺，质量保证承诺，以达到的绝热效果。
安全技术特性
低温液体二氧化碳储罐采用 “组合、安全系统阀”使用两组安全阀同时工作，在安全阀定期校验时可关闭一侧，另一侧继续工作，确保储罐的安全运行。
操作系统
储罐内容器上部设置了压力表，差压式液位计和液位对照表，可以随时掌握内容器储存量及压力变化，便于充装及排液时的操作。
检测系统
储罐下部设置了储罐真空检测、真空规管及真空阀可定期或随时用真空计进行检测夹层真空度，确保储罐的安全运行。

维护与检修 Maintenance and repair
【产品详情图片】
1.储罐的使用与维护，应按“压力容器安全技术监察规程”要求和本说明进行。
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.日常检查与维护 Daily inspection and maintenance
储罐在运行过程中，要经常检查安全阀、压力表、液位计工作是否正常，阀门管路是否有泄漏，外部有无异常现象，发现问题及时处理。
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.定期校验 Regular verification
3.1安全阀整定压力不大于2.27Mpa，每年至少校验一次，并加铅封，作好记录。
Safety valve setting pressure is not more than 2.27Mpa, at least once a year, and add seals, make a record.
3.2定期检查夹层真空度，未装低温介质的情况下真空度应低于65Pa，装有低温介质的情况下，真空度应低于10Pa为合格。
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.

充液的操作 filling operation
【标题】
充液分为充液和补充充液。
充液的操作如下：
Filling fluid is divided into the first filling and filling fluid.
The first filling operation is as follows:
2.1.1 储罐吹除置换干净达到要求后，将充液管线与储罐的充液接头连接，液位计组合阀处于平衡状态准备充液。
After the tank blows off to replace the cleanliness meets the requirements, the filling liquid line is connected with the liquid filling joint of the tank, and the liquid level gauge combination valve is in an equilibrium state to be filled.
2.1.2充入与液体二氧化碳纯度相同的气体，使罐内压力达到0.8 Mpa以上，方可进行充液。 filled with the same purity of liquid carbon dioxide gas, the tank pressure reached 0.8 Mpa above, before filling.
2.1.3 将充液管线接通槽车，先开启V5残液阀，排出管线内的杂质气体后，再开启V1进液阀和V7排气阀，V8液位计组合阀处于全开状态，显示液位计读数进行充液。
The filling liquid line connected tanker, first open the V5 raffinate valve, exhaust gas impurities within the pipeline, and then open the V1 inlet valve and V7 exhaust valve, V8 level gauge combination valve is fully open state, Display level meter readings are filled.
2.1.4 在充液过程中，当液位计指示液位接近标定值时，可间断开启V4充满指示阀，如有液体喷出，应立即停止充液，关闭V4充满指示阀。
During the filling process, when the liquid level gauge indicates the liquid level approaches the calibration value, the V4 may be intermittently opened to indicate the valve. If any liquid is ejected, liquid filling should be stopped immediately and the V4 valve should be closed.
2.1.5关闭V1进液阀和V7排气阀，打开V5残液阀，拆下充液管线，充液结束。
补充充液的操作与充液的操作方法相似，不同点是补充充液时一开始就可以大量充液。
Close the V1 inlet valve and the V7 exhaust valve, open the V5 residual valve, remove the filling line, and fill with liquid.
The procedure for replenishing the priming solution is the same as for the first priming procedure, except that the priming solution can be replenished extensively from the beginning.
