Technical Field

The invention relates to the technical field of gas storage equipment, in particular to a detection system for a vertical lift wet-type gas holder.

Background

The whole wet-type gas holder is of a fully-welded steel structure, is a cylindrical high-rise structure, has a large diameter, and requires the bell jar to be relatively stably and smoothly lifted in operation without clamping stagnation and abrasion; the bell cover slides with an outer guide wheel arranged on the bell cover by a guide rail fixed on the inner side of the water tank and a guide frame rail outside the water tank, and slowly rises or falls. The outer guide frame type vertical lifting gas holder is adopted for a wet gas holder of 20 ten thousand ton/year polyvinyl chloride engineering in a certain plant.

The outer guide frame type helicopter gas cabinet only detects the pressure, the water level, the cabinet volume and the cabinet speed, and does not measure the inclination of the bell jar and the stress condition of the guide wheel. The low-pressure wet gas holder is not allowed to be excessively inclined, the excessive inclination cannot guarantee the gas sealing requirement, and the guide wheel and the guide frame are seriously abraded due to the excessive inclination, so that the lifting of the bell jar is failed, and safety accidents are caused.

Therefore, the detection of the inclination of the wet gas holder is a very necessary measure and is a guarantee for the safe operation of the system.
