Description

一种自动化氪氙气体的连续冲瓶装置A continuous bottle flushing device for automatic krypton xenon gas

技术领域technical field

本发明涉及的是空分装置气体充瓶工艺装备，属于空分装置技术领域。The invention relates to process equipment for filling gas bottles of an air separation unit, and belongs to the technical field of air separation units.

背景技术Background technique

氪氙稀有气体产量少，从冷箱里分流塔产出的氪氙气体流量小，压力低，无法直接链接气瓶充瓶。采用小型液化和汽化设备投入成本高，且设备体积大、能耗高。因此从充瓶原理上采用液氮冷冻法，液化氪氙稀有气体进行存储。液氮原料价格低廉，效果直接，是一种理想的降温手段。氪氙充瓶装置采用一只高压气瓶存储，分冷冻和复热两个不同阶段，需要将气瓶浸泡液氮一段时间后，脱离液氮进行常温水加热，所以液氮罐和气瓶之间主要靠升降机构实现气瓶在液氮罐中的浸泡和脱离。但是常温水喷淋气瓶之前需人工将液氮罐搬离原位置，手动打开水阀，喷淋铝气瓶表面汽化氪氙，进行充瓶。如此重复作业，人工工作量大，每隔一段时间进行切换，且手动式升降机构并不安全可靠，液氮罐重量不小，搬上搬下，定位不准，每次切换需要调整液氮罐位置，以便铝瓶能伸入液氮罐浸泡到位。因此充瓶效率不高，而且非常容易出错，存在安全隐患。The production of krypton xenon rare gas is small, and the krypton xenon gas produced from the split tower in the cold box has a small flow rate and low pressure, which cannot be directly connected to the gas bottle filling. The cost of using small liquefaction and vaporization equipment is high, and the equipment is large in size and high in energy consumption. Therefore, from the principle of filling the bottle, the liquid nitrogen freezing method is used to liquefy krypton and xenon rare gas for storage. Liquid nitrogen is an ideal cooling method because of its low price and direct effect. The krypton-xenon bottle filling device uses a high-pressure gas bottle for storage, which is divided into two different stages: freezing and reheating. The immersion and detachment of the gas cylinder in the liquid nitrogen tank is mainly achieved by the lifting mechanism. However, before spraying the gas cylinder with normal temperature water, it is necessary to manually move the liquid nitrogen tank away from the original position, manually open the water valve, and spray the surface of the aluminum gas cylinder to vaporize krypton and xenon to fill the bottle. Such repeated operations require a large amount of manual work, switching every time, and the manual lifting mechanism is not safe and reliable. The weight of the liquid nitrogen tank is not small, and the positioning of the liquid nitrogen tank is not accurate. Position so that the aluminum bottle can reach into the liquid nitrogen tank to soak in place. Therefore, the bottle filling efficiency is not high, and it is very error-prone, posing a safety hazard.

发明内容SUMMARY OF THE INVENTION

The electronic control system is used to overcome the inefficiency of alternate storage and bottle filling in the original manual operation. Add a set of high-pressure storage gas cylinders, and make full use of the idle time generated during the process of manually switching the valve for storage or filling. The two processes of storage and bottle filling are seamlessly connected and carried out uninterrupted, thereby improving the efficiency of bottle filling.

本发明涉及一种氪、氙气体充瓶方法，其特征主要体现在能连续不间断充瓶工作。充瓶过程包括：氪氙气体的冷冻、液化、存储、复热、汽化、充瓶这六个步骤。然而这六个步骤是一个循环往复的交替过程。常温常压下氪气液化温度-151.8℃，氙气液化温度-109.1℃。本发明的有益效果：该装置采用一套存储、另一套充瓶两套气瓶，利用液氮（-196℃）浸泡气瓶对氪氙气体进行液化，通过PLC控制系统设定时间间隔，对电动阀进行切换，控制一只气瓶浸泡液氮罐中进行冷冻存储，另一只气瓶正在执行常温水加热充瓶状态，一定时间后，相互切换，把冷冻存储和复热充瓶两个状态无缝连接，实现连续性交替工作，不间断的进行充瓶目的，既提高充瓶效率，降低劳动强度，又提高操作安全性。The invention relates to a bottle filling method with krypton and xenon gas, which is mainly characterized in that it can continuously and uninterruptedly fill the bottle. The bottle filling process includes six steps: freezing, liquefaction, storage, reheating, vaporization, and bottle filling of krypton and xenon gas. However, these six steps are an iterative process. Under normal temperature and pressure, the liquefaction temperature of krypton gas is -151.8℃, and the liquefaction temperature of xenon gas is -109.1℃. The beneficial effects of the invention are as follows: the device adopts two sets of gas cylinders for storage and the other for filling, and uses liquid nitrogen (-196°C) to soak the gas cylinder to liquefy the krypton and xenon gas, and set the time interval through the PLC control system, Switch the electric valve to control one gas cylinder to be immersed in the liquid nitrogen tank for refrigerated storage, and the other gas cylinder is being heated and filled with normal temperature water. The states are seamlessly connected to achieve continuous alternate work and uninterrupted bottle filling, which not only improves bottle filling efficiency, reduces labor intensity, but also improves operational safety.
