玉树啤酒厂二氧化碳储罐

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

常见故障的处理 Common fault handling
【产品详情图片】
1.内罐压力异常长高 Inner tank pressure abnormally high
1.1可能是V3回气阀开度过大或阀门失灵，应减小阀门开度或检修阀门。
May be V3 return valve opening is too large or valve failure, should reduce the valve opening or valve repair.
1.2可能是S1、S2安全阀失灵，到启动压力不启动，应检查安全阀。
may be S1, S2 safety valve failure, to start the pressure does not start, check the safety valve.
1.3可能是压力表指示不准确，应校验压力表。
may be pressure gauge indicates inaccurate, should verify the pressure gauge.
2.液位计指示不真实 Level gauge instructions are not true
2.1可能是液位计失灵，应检修液位计。
may be the level gauge failure, should be maintenance level gauge
2.2可能是液位计接头处泄漏，应检修接头连接处，排除泄漏。
It may be a leak at the head of the liquid level gauge. It should repair the connection of the joint and eliminate the leakage
3.蒸发率高，外壳体凝水结霜 High evaporation rate, the outer shell condensate frost
3.1可能是珠光砂未填实或下沉，应补充珠光砂，重新抽真空。
may be unfilled or sinking of pearl sand, pearl sand should be added and re-evacuated.
3.2可能是真空度恶化，应进行真空检漏，重新抽真空。
may be a deterioration of the vacuum, vacuum leak detection should be carried out, re-vacuum.
4.管道阀门液体流动不畅或堵塞 pipeline valve fluid flow or blocked
可能是液体二氧化碳形成干冰的原因造成，应停止使用，用热空气加温管阀至畅通为止。May be caused by the formation of dry ice, should stop using, with hot air heating pipe valve until smooth.

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".

储罐的增压 Tank pressurization
【产品详情图片】
当储罐向外供液又需要稳定排液压力时，可利用汽化器（另外配备）进行增压。其操作过程如下：
The carburetor (available separately) can be used for boosting when the reservoir is supplied externally and requires stable discharge pressure. The operation is as follows:
2.3.1开启V2排液阀，使液体二氧化碳汽化器汽化，开启V3回气阀（根据用户回气管路的设置，V3回气阀可置于常开状态）从汽化器分流出来的气体返回储罐上部，使储罐内增压。
Open the V2 drain valve to vaporize the liquid carbon dioxide vaporizer and open the V3 return valve (the V3 return valve can be normally open depending on the return air line of the user). The gas diverted from the vaporizer returns to the upper part of the tank , So that the pressure tank.
2.3.2当储罐内压力达到2.1Mpa时，可暂时关闭V3回气阀。
When the tank pressure reaches 2.1Mpa, the valve can be temporarily closed V3 return gas valve.
2.3.3排液过程中，可通过控制V3回气阀的开度，使增压能力维持在压力稳定的水平。
During drainage, the degree of pressurization can be maintained at a pressure-stable level by controlling the opening of the V3 return valve.
