Steam pipeline drainage method and system capable of responding in advance, equipment and medium

Abstract

The invention discloses a steam pipeline drainage method and system capable of responding in advance, equipment and a medium. A steam pipe network is divided into a plurality of measuring points, and the temperature and pressure of steam in a pipeline at each measuring point are obtained in real time; according to the sequence of the measurement points from near to far away from a drain valve and according to the temperature and pressure of steam in the pipeline at each measurement point, whether the interior of the pipeline at each measurement point is in a liquid phase region or not is judged in sequence; if the interior of the pipeline at one measuring point is in the liquid phase region, the opening time t of the drain valve is calculated according to the distance between the measuring point and the drain valve; and whether all the measuring points are in the liquid phase region or not is judged. Whether condensation water exists in a pipe network or not can be sensed in advance, then a steam trap can be controlled to be turned on in time by obtaining the turning-on time of the steam trap, the turning-on time of the steam trap is accurately controlled, the condensation water is discharged in time, and safe operation of the pipe network is guaranteed.

Description

technical field [0001] The invention belongs to the field of heat supply, and relates to an early response steam pipeline drainage method, system, equipment and medium. Background technique [0002] Steam from power plants can deliver stable, high-quality steam to industrial plants. Due to the loss of heat dissipation during the steam transmission process, some steam may condense into a liquid phase; when there is too much liquid phase in the pipeline, it may cause water hammer and cause hidden dangers to the safe operation of the pipeline network. Therefore, it is necessary to add a drainage system to the pipe network. The traditional drainage system relies on manual experience control, which may not be able to respond to the poor operation status of the pipe network in time. When condensed water is generated in the pipe network, the condensed water cannot be discharged in time. Contents of the invention [0003] The purpose of the present invention is to overcome the ab...

Due to heat loss during steam transmission, part of the steam may condense into a liquid phase; when there is too much liquid phase in the pipeline, it may cause water hammer and cause hidden dangers to the safe operation of the pipeline network

Therefore, it is necessary to add a drainage system to the pipe network. The traditional drainage system relies on manual experience control, which may not be able to respond to the poor operation of the pipe network in time. When the condensate is generated in the pipe network, the condensate cannot be discharged in time.
