AI Technical Summary

Technical Problem

The existing safety and explosion-proof system of the hydrogen storage area in the hydrogen production and refueling station lacks active directional dispersion function. Traditional mechanical ventilation is inefficient and cannot quickly dissipate a large amount of hydrogen in a short time. It cannot accurately respond to directional leaks and poses a risk of sympathetic explosion.

Method used

Design an explosion-proof dispersion system, including an air pipeline module and a monitoring and communication module. It utilizes a high-speed airflow to spray out from the air outlet and guide the hydrogen cloud upward. Combined with the stratification characteristics of natural wind gradient, it achieves accurate response and rapid dissipation of directional leaks through high-precision sensors and independent branch control valves.

Benefits of technology

It achieves millisecond-level response to hydrogen leaks, promotes precise and directional dispersion, significantly improves the explosion-proof safety of the system, reduces the risk of hydrogen cloud accumulation in the hydrogen storage area, and enhances overall safety and efficiency.

Abstract

The invention discloses an explosion-proof dispersion promoting system for a hydrogen storage area of a hydrogen production and hydrogenation integrated station and application. The explosion-proof dispersion promoting system comprises an air pipeline module and a monitoring communication module. The monitoring module detects leakage through a tank pressure and multi-azimuth hydrogen concentration sensor, an accident judgment unit judges the accident grade and controls a corresponding branch control valve and a main valve to be opened, a high-speed air outlet vertically and upwards sprays airflow, a firewall is matched to guide combustible hydrogen cloud to move to the high position, and dissipation is accelerated by means of natural wind gradient. And fire blast accidents caused by hydrogen cloud gathering are prevented. According to the system, millisecond-level response and directional accurate dispersion promotion are realized, the defects of low dispersion promotion efficiency and no directional response of the existing system are overcome, and the safety of the integrated station is greatly improved.
