A gas holder is a container device used for storing various industrial gases or balancing the non-uniformity of the gas consumption, and is often used for storing gas substances used or obtained in the industrial production process in the industries of petroleum, chemical industry, medicine and the like. Among them, the gas tank can be classified into a low pressure gas tank and a high pressure gas tank according to the pressure requirement of storage. Most industrial gases do not have strict requirements on storage pressure, so low pressure gas cabinets are used much more widely than high pressure gas cabinets. The low-pressure gas holder is divided into a wet structure and a dry structure.
The wet low-pressure gas holder is the simplest and common gas holder, is usually used for gas storage wet gas holders, and consists of a water seal tank and a bell jar. The bell jar is a cylindrical container which has no bottom and can move up and down. If the gas storage capacity is large, the bell jar can be changed into a multi-layer sleeve from a single layer, and all the sections are sealed by water-sealed annular grooves. When fuel gas is fed, the gas holder is raised, when the fuel gas is discharged, the gas holder is lowered, the common measuring instrument is limited by the cable, the long-term safe on-line operation can not be realized, and the liquid level measurement of the fuel gas holder is accurate and continuous and can directly influence whether the fuel gas holder can be safely operated.
