Steam heat supply network steam trap inspection and discharge operation scheduling method and operation scheduling system

Abstract

The invention relates to an inspection and discharge operation scheduling method and an operation scheduling system for a steam trap of a steam heat supply network. The inspection and discharge operation scheduling method for the steam trap of the steam heat supply network comprises the following steps: acquiring measured values of steam parameters; constructing a corresponding digital twinning model of an actual heat supply steam pipe network under the current working condition according to the measured values of the steam parameters; obtaining predicted values of the steam parameters according to the corresponding digital twinning model of the actual heat supply steam pipe network under the current working condition; judging whether the heat supply steam pipe network operates abnormallyor not according to the predicted value and the measured value; when the heat supply steam pipe network operates abnormally, the corresponding manual steam trap needing to be adjusted is judged, and an operation order is generated; the corresponding manual steam trap is adjusted according to the operation order; according to the method, the heat supply steam pipe network is monitored, whether theoperation of the heat supply steam pipe network is abnormal or not is judged, the purposes that inspectors are scientifically guided to conduct discharging operation on the manual steam trap in the heat supply steam pipe network, and a heat supply network area with a larger range is managed more scientifically with less manpower are achieved, the operation cost is reduced, and the operation safetyis improved.

Description

Technical field [0001] The invention belongs to the technical field of smart energy and industrial Internet, and specifically relates to a method and an operation scheduling system for the patrol inspection and discharge operation of steam heating network steam traps. Background technique [0002] At present, my country is paying more and more attention to the treatment and protection of air pollution, and many small boilers of production enterprises have been dismantled and replaced with centralized heating pipe networks. The heating pipe network is increasing rapidly in all parts of our country, and there are often phenomena such as climbing over mountains and ridges, crossing tunnels, crossing lakes and seas, and passing through residential areas. The routing of heating pipe networks is more complicated than before. Uncontrollable factors such as typhoons and mountains Safety hazards caused by factors such as landslides, floods, and man-made damage have also increased signific...

Problems solved by technology

However, the existing patrol inspection method is mainly based on the judgment of operating experience. There may be reasons such as the manual drain valve not being opened in time or the opening time being too short, resulting in the condensate not being fully discharged in time; or the drain valve being opened for too long and not closed tightly. Lead to a large amount of leakage of steam in the pipeline, resulting in economic losses and potential personal and property safety hazards

[0005] As the scale of the steam heating network continues to expand, the manpower required for inspections is also expanding, resulting in continuous increases in operating costs, but the operating efficiency has not been effectively improved; at the same time, there are insufficient personnel in some areas, resulting in the need for each inspection personnel The inspection area is too large to completely cover the inspection area, and there are many difficulties in the operation and maintenance of the steam heating network
