Automatic explosion suppression device of water mist of vaporous cloud explosion induced by release premixed flame and explosion suppression method thereof

Abstract

The invention relates to an automatic explosion suppression device of water mist of vaporous cloud explosion induced by release premixed flame and explosion suppression method thereof. The automatic explosion suppression device comprises a gas explosion venting device, a hemispherical vapor cloud device and an explosion suppression device; the gas explosion venting device is composed of a gas channel, a reducing joint and an explosion venting port channel; a sensor is installed in the middle inner cavity of the gas channel; an explosion venting port is formed in the tail end of the explosion venting port channel; the hemispherical vapor cloud device is composed of hemispherical diaphragm seal premixed gas; the explosion suppression device is composed of a sensor, a controller and an explosion suppression machine, the explosion suppression machine is composed of a high pressure water pipe, a high pressure valve, a electromagnetism valve and a spray nozzle device. When a channel is overpressure and reaches a set value of a rupture disk, the rupture disk is cracked; pipe flame signal is received through the sensor and order is given through the controller, so that cooling and the fireextinction of the premixed flame and hemispherical vaporous cloud are carried through the spray nozzle device. According to the automatic explosion suppression device of the water mist of vaporous cloud explosion induced by the release premixed flame and the explosion suppression method thereof, structure is reasonable, practicality is high, dismantle is facilitated and change is convenient, multiple explosion suppression details are considered and explosion suppression is scientific and efficient.

Description

technical field [0001] The invention relates to a fine water mist automatic explosion suppression device and explosion suppression method for steam cloud explosion induced by an explosion venting premixed flame, which is used to control the explosion venting premixed flame to eliminate the possibility of vapor cloud combustion and explosion hazard. Background technique [0002] Whether in industrial or agricultural production, manufacturing, storage, and transportation, there are large or small hidden dangers of combustion and explosion, especially in mines and pipeline transportation, which are more likely to cause serious casualties and property losses. Therefore, the development of explosion venting technology plays an important role in reducing the incidence of explosion accidents in confined spaces. [0003] Explosion venting is to discharge the high-temperature and high-pressure combustibles and overpressure airflow through the pressure relief port during the initial o...

AI Technical Summary

Problems solved by technology

[0005] Most of the studies on water mist explosion suppression are considered in gas pipelines and coal mines, but there is a lack of more specific implementation plans for flame explosion suppression at explosion vents and steam cloud explosion suppression, so for explosion vents Water mist explosion suppression of premixed flame-induced vapor cloud explosion has a huge research demand and implementation significance
