Dust Explosion Suppression and Systems

The chemical explosion suppression system continuously monitors the pressure or infrared radiation, and in the event of an explosion, rapidly releases the fire extinguishing solvent in the suppressor to prevent high pressure propagation caused by the explosion of combustible dust inside the equipment or the container, thereby preventing the container from being exceeded. Or the design strength of the device.
