The charged water mist is spirally accelerated after passing through the worm flow guider 11 and then is sprayed in a bowl shape through the flow expander 12, so that the spraying distance and the coverage range are increased.

As shown in fig. 2, which is a cross-sectional side view of a fire suppression device based on charged water mist, an ultrasonic atomizer 3 is fixed at the bottom of a water storage tank 2, an auxiliary fan 4 is arranged at the upper part of the water storage tank 2, the wind direction faces the inside of the water storage tank 2, and an axial flow fan 7 is arranged at the tail end of an air duct 8; the corona ring 10 is arranged at the middle section of the air duct 8, and the insulator 9 is arranged at a gap between the air duct 8 and the corona ring 10; the worm flow guider 11 is welded in the wind tube 8 and is positioned between the corona ring 10 and the flow expander 12;

when the system starts to operate, the high-voltage power supply 10s is firstly turned on, the negative corona area formed by the corona ring 10 connected with the negative electrode of the high-voltage power supply is ensured to be stable, and then the ultrasonic atomizer 3, the auxiliary fan 4 and the axial flow fan 7 are started. The ultrasonic atomizer is connected with a 1.7MHz frequency oscillation circuit. The ceramic atomization plate generates high-frequency resonance, water is scattered into dry mist level water mist of 1-5 um, a large amount of negative ions are generated, due to the air pressure of the auxiliary fan 4 and the negative pressure in the air duct 8, the fine water mist rises into the air duct along the hose 6, is subjected to charge in a corona area generated by the corona ring 10, is accelerated spirally through the worm flow guider 11, and is sprayed out in a bowl shape through the flow expander 12, the coverage range is wide, and the spraying distance is long.

Taking gas explosion combustion as an example, the following charged particles are formed:

o2+ e- + MO-2 + M (reaction of electrons and oxygen)

CH + O CHO + + e-and CH (a4 sigma-) + O CHO + + e-

CHO+H2O H3O++CO+e－

O- + HCN CN- + OH and OH- + HCN CN- + H2O

During the chemical reaction process of gas explosion combustion, a large amount of free radicals with unpaired electrons and intermediate products are generated, and the intermediate products and the free radicals are used as activation centers to participate in the gas explosion combustion process. The charged water mist is applied to break the balance distribution of positive ions and negative ions in flame propagation, accelerate the capture, adsorption and neutralization of the charged water mist on intermediate reaction particles with different polarities, and reduce the particle concentration and distribution gradient in a flame chemical reaction area under the action of micro-electric field force, so that the chain reaction of free radicals is disturbed to achieve the effect of inhibiting combustion and explosion.

In addition, due to the interaction of electric field force, the viscous resistance and the tension on the surface of the charged fine water mist droplets are reduced, the particle size of the droplets is smaller, the droplets are more uniformly distributed in explosion flame, and the contact area of the droplets with the flame frontal surface is larger, so that the absorption of the droplets to heat in the reaction process is accelerated, the heat in the reaction process is reduced, and the purpose of suppressing fire is achieved.
