A stable, rapid and automatic water replenishment system for a torch water-sealed tank

Abstract

The invention discloses a stable and quick automatic water replenishing system of a torch water-sealed tank. A first water replenishing pipeline and a second water replenishing pipeline are respectively connected between a water replenishing tank and the water-sealed tank; a first control valve is arranged on the first water replenishing pipeline; a second control valve is arranged on the second water replenishing pipeline; a first liquid level indication controller is arranged on the water-sealed tank; the first control valve and the second control valve are respectively interlocked with the first liquid level indication controller; when the liquid level of the water-sealed tank falls to a first set liquid level, the first liquid level indication controller controls the first control valve to be opened; when the liquid level of the water-sealed tank falls to a second set liquid level, the first liquid level indication controller controls the second control valve to be opened; when the liquid level of the water-sealed tank rises to a third set liquid level, the first liquid level indication controller controls the first control valve and the second control valve to be closed; the first set liquid level is higher than the second set liquid level; and the third set liquid level is higher than the first set liquid level.

Description

technical field [0001] The invention relates to the petrochemical field, in particular to a stable and fast automatic water replenishment system for a torch water-sealed tank. Background technique [0002] The flare system is an important facility to ensure the normal production and accidents of petrochemical plants. It is used to deal with continuous or intermittent discharges of combustible gases and toxic Harmful combustible gases are converted into non-toxic and harmless non-combustible substances through combustion treatment to ensure the safe production of petrochemical plants. Therefore, the reliability of the flare system operation is very important. [0003] As a part of the flare system, the water-sealed tank plays an extremely important role. Its function is to prevent the flare pipe network and connecting equipment from being damaged when the flare flares backfire and explode; control facility. Usually, the water seal tank is equipped with a low liquid level a...

Problems solved by technology

At the same time, when the discharge of flare gas is large, it is very easy to cause severe fluctuations in the liquid level of the water seal, resulting in excessive water loss, the water seal may fail, and the pressure of the flare system will also fluctuate

In order to avoid causing major safety hazards to the operation of the flare system, the water sealing effect needs to be re-established in a short period of time, and the water supply pipelines designed and used under normal working conditions are difficult to complete the large amount of water required for water sealing in a short period of time
