二氧化碳储罐的定能特点
1. 安全运转: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封闭一侧,另一侧持续作业,保证储罐的安全运转。
3. 功能安稳牢靠:液态二氧化碳储罐具有功能安稳、操作保护便当、发动时间短、运转平稳等长处,产品全国。
二氧化碳储罐压力不能低于1.4MPa作业,二氧化碳液体在低于0.7MPa时会构成干冰,一旦构成干冰,储罐就很麻烦了,里边二氧化碳液体凝结成冰,将很难处理。
你所说的是二氧化碳储罐在运用过程中压力不断下降,为了避免不断下降压力,你如今需要添加一套二氧化碳子增压体系,此体系构成有两个有些;
为了维持低温情况,储罐有必要装备制冷机,当温度上升时,敞开制冷机,使二氧化碳储罐内温度下降到规划温度。在储罐上装备有压力表,一起为了便利用户运用,储罐上还装配了一台主动指示液面、称重计量的存量。
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.

2 储罐的操作Tank operation
【产品详情图片】
储罐的操作分为充液、贮存、增压、排液等过程,每个过程必须做到:V6三通截止阀(连接安全阀)和V8液位计组合阀始终处于全开状态。罐内压力不应高于2.16Mpa,压力不应低于0.8Mpa .
The operation of the tank is divided into filling, storage, pressurization, drainage and other processes, each process must be: V6 three-way valve (connecting safety valve) and V8 level gauge combination valve is always in the fully open state. Tank maximum pressure should not exceed 2.16Mpa, the minimum pressure should not be less than 0.8Mpa.

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.

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.

低温液体储槽的年检:
1、原始资料审查
⑴、对产品的出厂技术文件审查,包括内筒、外筒的材质证书和复验报告,不锈钢焊接工艺评定报告,焊缝探伤报告(含焊接返修部位的探伤报告),水压试验报告,气压(密)试验报告,氦泄露试验报告,蒸发率试验报告和真空度测试报告等资料。⑵、审查储槽运行记录,询问设备的管理、操作人员。在运行过程中压力有无明显
变化。安全阀是否起跳,蒸发量是否变大等。
2、外部检查
除按一般压力容器的要求进行外部检查,还应主要检查以下内容:
(l)各种阀门开闭是否正常;
⑵、压力表、液位计等安全附件是否按规定进行检验,其使用是否在校验期限内;
⑶、容器、管道和管阀连接处是否有泄露;
⑷、储槽的外表面(特别是外筒的顶部、底部外表面)是否有“冒汗”、“结霜”;
⑸、支腿的损坏,基础下沉、倾斜、开裂,紧固螺栓的完好情况。
3、壁厚测试
在外筒外侧选4~8点进行壁厚测试,确定小壁厚H;同时从外筒外侧测量外筒的直径D2,根据原始资料审查的记录的内简直径D1,按公式
(D2-H-D1)/2<300mm
4、内窥镜内筒内表面检查
检查内筒内表面的腐蚀情况。对可疑部位进行重点检查。
5、表面探伤(MT或PT)
对所有外筒接管角焊缝的外表面进行表面探伤,不能做磁粉探伤(MT)的部位进行渗透探伤(PT)。
6、真空度的测试
在冷态下,测试的真空度达到16Pa或安全阀起跳频繁、内筒异常升压时,需重新抽真空。
