二氧化碳储罐的长处
二氧化碳储罐是储存液态二氧化碳介质的储存压力容器。
二氧化碳储罐内胆原料选用16MnDR,二氧化碳罐外胆原料为Q245R或者Q345R。
二氧化碳罐选用“组合、安全体系阀”运用两组安全阀一起作业,在安全阀定时校验时可关闭一侧,另一侧持续作业,保证二氧化碳罐的安全运转。
二氧化碳罐选用热态下的珠光砂为绝热材料并抽真空,公司以共同的技术保证质量,以达到绝热作用。
二氧化碳罐具有运用寿命长、构造紧凑、占地面积少、集中控制、操作和维修便利等特色。
二氧化碳罐的规划压力为2.2MPa
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.

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.

性能特点
低温容器的性能 [2] 与特点工业用的液氮在低温度下由氮气加压变为无色液体,低温容器则此时液氮温度是很低的,然后用钢瓶盛放,然后再把钢瓶放到常温下,由于环境温度升高,则瓶内盛放的液氮温度升高,也变成常温,那么液氮在瓶内的压力会变得更高.
但是在实际情况下,要么钢瓶保温效果非常好,要么有卸压安全阀门,要么钢瓶开口放置时间非常短。钢瓶内温度不可能达到常温。
工业用的液氮在低温度下由氮气加压变为无色液体,则此时液氮温度是很低的,然后用钢瓶盛放,然后再把钢瓶放到常温下,低温储罐由于环境温度升高,则:
瓶内盛放的液氮会发生相变,即汽化,由液态氮变成气态氮,钢瓶压力升高,这个时候里面的温度还是液氮和气氮共存的温度,一般为-196℃,吸收外界热量温度继续升高则压力继续升高,卸压安全阀将会起作用,进行卸压,如果不卸压,只是升温,液氮在钢瓶内的压力就会便的非常高,造成高压容器爆炸。
液氮储罐保温效果是非常好的,液氮在里面可以保存1个月不汽化完。
