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.

【变量3】【变量2】【变量1】

1、高纯二氧化碳主要用于电子工业，二氧化碳激光器、检测仪器的校正气及配制其它特种混台气，在聚乙烯聚合反应中则用作调节剂。
2、固态二氧化碳广泛用于冷藏奶制品、肉类、冷冻食品和其它转运中易的食品，在许多工业加工中作为冷冻剂，例如粉碎热敏材料、橡胶磨光、金属冷处理、机械零件的收缩装配、真空冷阱等。
3、气态二氧化碳用于碳化软饮料、水处理工艺的pH控制、化学加工、食品保存、化学和食品加工过程的惰性保护、焊接气体、植物生长剂，在铸造中用于硬化模和芯子及用于气动器件。
还应用于杀菌气的稀释剂（即用氧化乙烯和二氧化碳的混台气作为杀菌、杀虫剂、熏蒸剂，广泛应用于医疗器具、包装材料、衣类、毛皮、工厂、文物、书籍的熏蒸）。
4、液体二氧化碳用作致冷剂，飞机、和电子部件的低温试验，提高油井采收率，橡胶磨光以及控制化学反应，也可用作灭火剂。
5、超临界状态的二氧化碳可以用作溶解非极性、非离子型和低分子量化合物的溶剂，所以在均相反应中有广泛应用

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.
