Abstract

The invention discloses a large-displacement oil-water separator for a gas holder. A main drainage system comprising a main drainage pipe and a liquid level detection component is arranged on the basis of the conventional oil-water separator. The separator can increase displacement, maintain an extremely small water level change of a bottom oil groove and realize the aim of controlling the oil level of the piston oil groove by using the oil-water separator, thus the separator is suitable for storing the gas with relatively high temperature, improves the heat value of the gas, saves the cooling water and ensures low use cost; and by increasing limited investment, the separator of the invention can greatly improve the drainage capability of the conventional oil-water separator, reduce the loss of the sealing oil and expand the application range of the thin-oil sealed type gas holder from the normal-temperature saturated gas to the gas holder of saturated gas with inlet temperature of about 70 DEG C and is connected in series with the gas pipeline.

Description

technical field

[0001] The invention relates to an accessory device of a gas cabinet, in particular to an oil-water separator for sealing circulating oil in a gas cabinet. Background technique

[0002] The gas cabinet is a steel container for storing industrial and civil gas. Because it holds gas, it has high requirements for its sealing performance. In the prior art, thin oil-sealed piston-type dry-type gas holders are more commonly used, and sealing oil is continuously supplied to the piston oil groove by means of closed-circuit forced circulation of sealing oil to maintain the height of the oil groove oil seal and prevent gas from escaping. The oil supply device includes an oil supply pump and piping, a reserve oil tank, an overflow device and an oil collecting plate on the piston, which together form a piston sealing oil supply device to supply oil to the piston oil groove to ensure the sealing oil level of the piston oil groove.

[0003] During use, since the circulati...
