发明名称 Ignition and fire suppressor
摘要 An ignition and fire suppressing system for an electrostatic sprayer of the type having a high voltage supply for creating an electrostatic charge and a nozzle in flow communication with a pressurized coating material source and a pressurized atomizing gas source. The system includes a high voltage arc-detecting circuit for sensing the presence of an ionizing arc or spark and for disabling the high voltage supply to the sprayer; a pressurized non-ignitable fire suppressing gas source in flow communication with the sprayer nozzle; and solenoid valves connected between the sprayer nozzle and the coating material, atomizing gas and fire suppressing gas sources which are actuated by an output from the arc-detecting circuit.
