Storer and troubleshooting method, device and equipment for hydrogen pipe network

Abstract

The invention discloses a storer and a troubleshooting method, device and equipment for a hydrogen pipe network. The method comprises the steps that hydrogen supply sampling values are acquired for various devices in a hydrogen supply unit within the reasonable fluctuation range of hydrogen supply data, and hydrogen consumption sampling values are acquired for various devices in a hydrogen consumption unit within the reasonable fluctuation range of hydrogen consumption data; according to the hydrogen supply sampling values and the hydrogen consumption sampling values in each combined manner, calculation of working condition data of pipe segments and joints in the hydrogen pipe network under the combined manners is carried out; failure working condition data are confirmed according to the preset reasonable working condition data range of each pipe segment or joint; the un-reasonable combination is confirmed according to the failure working condition data; and whether the acquired hydrogen supply data of the devices in the hydrogen supply unit and the acquired hydrogen consumption data of the devices in the hydrogen consumption unit belong to the un-reasonable combination or not is judged. By means of the storer and the troubleshooting method, device and equipment for the hydrogen pipe network, failures in the hydrogen pipe network can be effectively reduced, and losses caused bythe failures of the hydrogen pipe network can be reduced.

Description

technical field [0001] The invention relates to the petrochemical field, in particular to storage and hydrogen pipeline network troubleshooting methods, devices and equipment. Background technique [0002] The hydrogen system of a refinery is usually composed of a hydrogen supply unit, a hydrogen consumption unit, a hydrogen recovery unit, and a hydrogen pipeline network. An important basis for the realization of optimization. The main functions of the hydrogen pipeline network are: transporting hydrogen of various purity to the hydrogen consumption unit; responsible for transporting the exhaust gas of the hydrogen consumption unit to the hydrogen recovery unit or the gas system; at the same time, maintaining a stable pressure field, The velocity field ensures the correct flow direction of the hydrogen-containing fluid. [0003] During the production process, the hydrogen pipeline network will have problems such as fluctuations, condensate, and pressure. Fault diagnosis i...

AI Technical Summary

Problems solved by technology

[0003] During the production process, the hydrogen pipeline network will have problems such as fluctuations, condensate, and pressure. Fault diagnosis generally requires the experience of the staff to make a rough judgment after the fault occurs. Therefore, not only will it cause losses because the fault has already occurred, but it will often cause fault judgment errors, and thus the normal operation of the hydrogen system
