Description

Technical Field

[0001] The utility model relates to the technical field of sulfur gas field sampling, in particular to a flare liquid separation tank quick sampling device suitable for high sulfur gas fields. Background Art

[0002] At present, there are two ways to sample gas field water in some gas fields. The gas-liquid mixed output station uses the sampling device connected to the sewage pipeline of the multiphase flow or water separator to sample, and the gas-liquid separate output station uses the magnetic flap level gauge of the flare separator tank or the acid buffer tank to sample. Under normal production conditions, the flare separator tank and the acid buffer tank are mostly in a state of micro-positive pressure or normal pressure, so the liquid sample can be directly obtained from the lower part of the magnetic flap level gauge. Usually, the sampling is to remove the plug at the bottom with a wrench, open the ball valve to take out the sample, and the magnetic flap level gauge is also located at a high position. When sampling, the personnel have to hold the bottle by hand, and also A funnel is needed to prevent sewage from leaking. Although it is under normal pressure and the risk is very low, it is inevitable that sewage will leak or get on clothes. In addition, due to the structure of the magnetic flap level gauge, the accumulated liquid at the bottom is not the latest discharged from the well, so this section of old liquid needs to be replaced and discharged before sampling. Only in this way can the water sample most recently discharged from the well be obtained, and the analysis results will be more accurate. Discharging the old liquid requires another bucket to hold it. It is very troublesome to keep switching between replacement and sampling, which is both risky and time-consuming.
