Spark Detection & Extinguishing System

Infrared Millisecond Detection & High-Pressure Water Fog Suppression

Highlights

Highly sensitive optical sensors detect invisible infrared sparks in pneumatic ducts in milliseconds.
Central controller triggers high-pressure water fog nozzle to extinguish sparks without stopping production.
Prevents dust collector filter bag fires and catastrophic silo dust deflagrations.
Supports 1 to 4 independent pipeline monitoring loops per controller module.

Performance Features

Optoelectronic sensor optics penetrate dense dust streams to spot thermal radiation sparks at temperatures down to 400°C without false alarms.

Specialized fast-acting solenoid valve creates a dense 120° cone water fog wall within 100 ms, quenching sparks using minimal water volume.

Monitors sensor health, water pressure, and battery backup continuously, logging all spark events with precise timestamps for plant audit compliance.

How much water is injected into the duct during spark quenching?

The mist nozzle injects less than 5 liters of atomized water per spark event, which evaporates rapidly without wetting the duct interior.
