Fire suppression system based on charged water mist and implementation method

Abstract

The invention relates to fire suppression equipment based on charged water mist. The fire suppression equipment based on the charged water mist comprises an air duct, a worm current guiding device, acorona ring, an insulator, an axial flow fan, a current enlarging device, a hose, a fixing frame, a water storage tank, an auxiliary fan, an ultrasonic atomizer and universal wheels. A small water mist of a dry fog grade is generated through the ultrasonic atomizer, and the small water mist rises into the air duct under the action of the auxiliary fan and the axial flow fan, through the corona ring being connected with a negative electrode of a high voltage power supply, a corona zone is formed by the corona ring under the action of high voltage electricity, the small water mist is charged after passing through the corona zone, and the charged water mist is accelerated in a track in which the worm current guiding device carries out spiral, and then the water mist is ejected in a bowl shapethrough the current enlarging device. According to the fire suppression equipment based on the charged water mist, the coverage area is wide, the influence on objects in the fire area is little, andthe fire extinguishing effect and the explosion suppression effect are remarkable.

Description

technical field [0001] The invention relates to the field of fire suppression and explosion suppression by charged water mist, in particular to a fire suppression system and implementation method based on charged water mist, which is suitable for fires caused by chain reactions in combustion mechanisms. Background technique [0002] Due to its physical and chemical properties, fine water mist has been widely used in different types of fires, and experimental studies have shown that under certain conditions, fine water mist also has a good inhibitory effect on the spread of explosion flames. In order to further improve the utilization efficiency of fine water mist and improve the physical and chemical properties of fine water mist, the fire extinguishing effect of charged fine water mist was studied, which showed that the extinguishing effect of charged fine water mist on oil pool fire was better than ordinary fine water mist; In addition, the wet fire extinguishing of simple...
