Steam pocket liquid level display control method, storage medium and electronic equipment

Abstract

The invention provides a steam pocket liquid level display control method, a storage medium and electronic equipment. The steam pocket liquid level display control method comprises the steps that steam pocket state information is obtained, the steam pocket state information comprises the real-time steam pocket steam temperature, the real-time steam pocket steam pressure, the real-time steam pocketsteam flow, the real-time steam pocket liquid level and the real-time water supply and inlet flow; the real-time steam pocket steam flow and the real-time steam pocket liquid level are corrected according to the real-time steam pocket steam flow and the real-time steam pocket steam pressure to obtain target steam pocket steam flow and a target steam pocket liquid level; a water inlet flow set value is determined according to the target steam pocket liquid level and a preset steam pocket liquid level, and a target water supply and inlet flow is controlled according to the water inlet flow setvalue and the real-time water supply and inlet flow; and the display of the steam pocket liquid level is controlled according to the target steam pocket liquid level, the target steam pocket steam flow and the target water supply and inlet flow. According to the steam pocket liquid level display control method, the steam pocket liquid level is automatically controlled, and the steam pocket liquidlevel control and display accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to a control method for liquid level display of a steam drum, a storage medium and electronic equipment. Background technique [0002] The boiler is an indispensable power equipment in the industrial process. The task of the boiler is to deliver a certain quality and a corresponding amount of steam according to the change of the external load. The steam drum liquid level is an important monitoring parameter in the operation of the boiler. It reflects the boiler load and The dynamic balance relationship of water supply, if the liquid level is too high, it will affect the effect of steam-water separation, resulting in the phenomenon of steam carrying liquid; if the liquid level is too low, it will destroy the water cycle, affect the operation of equipment, and easily cause all the water to vaporize and burn the boiler or even explode. It is an important condition to ensure th...

Problems solved by technology

[0004] However, the existing steam drum liquid level control can normally control the small fluctuations under the design working conditions. In the abnormal process fluctuations or the heating and cooling operation of the cracking furnace, the system can be realized by setting alarms, overriding, high and low selection and interlocking. Safe operation. For emergency operations such as abnormal process fluctuations or heating and cooling operations of cracking furnaces, operators still need to make on-site judgment operations or human intervention. The accuracy of steam drum liquid level indication and the control stability of the system are low, and it is impossible to realize device automation. Lifting and Safety Controls
