Abstract

The invention provides a liquid level meter flushing device and a crude oil gathering and transportation system. The liquid level meter flushing device comprises a flushing tank, a first pipeline and a second pipeline, wherein the flushing tank comprises a flushing tank body, and a liquid outlet, a pressure leading port and a liquid charging port arranged on the flushing tank body; the liquid outlet is positioned at the bottom of the flushing tank body; the pressure leading port and the liquid charging port are positioned at the upper part of the flushing tank body; the liquid outlet communicates with a lower liquid inlet of a liquid level meter through the first pipeline; a first valve is arranged on the first pipeline; the pressure leading port communicates with an upper pressure balance port of the liquid level meter through the second pipeline; a second valve is arranged on the second pipeline; and a third valve is arranged between the liquid charging port and the flushing tank body. The liquid level meter flushing device effectively solves the problem of higher cleaning difficulty of the liquid level meter in the prior art.

Description

technical field [0001] The invention relates to the technical field of petrochemical industry, in particular to a liquid level gauge flushing device and a crude oil gathering and transportation system. Background technique [0002] Oil-gas two-phase separators and oil-gas-water three-phase separators are commonly used in crude oil gathering and transportation systems. Both separators have magnetic flap level gauges. The magnetic flap level gauges are composed of water bags, magnetic floating balls, and containment The cavity of the floating ball, the flap box (red and white two-color magnetic small flaps) and so on. On the basis of realizing the local display of the liquid level, the liquid level gauge adds remote monitoring. The water bag with the upper opening is installed inside the separator and connected with the lower pipeline of the liquid level gauge. If the water bag is soaked in the oil-water mixture for a long time, there will be sludge and other impurities depo...
