大庆15立方二氧化碳储罐

液体的排放 liquid discharge
【产品详情图片】
2.4.1液体二氧化碳的正常排放是在储罐增压后，开启V2排液阀，V3回气阀，液体二氧化碳便流入汽化器汽化，供使用点使用。
The normal discharge of liquid carbon dioxide is after pressurization of the tank, open the V2 drain valve, V3 return valve, the liquid carbon dioxide will flow into the vaporizer vaporization for use point.
2.4.2为满足排液过程的稳定压力，应按“储罐的增压”操作方法进行增压。
In order to meet the steady pressure of the drainage process, it should be pressurized according to the method of "pressurized tank".

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

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.
