After the detector is triggered, the extinguishing device (e.g. water jet, nitrogen injection) needs to be activated within 0.5 seconds, cutting off the feed and power supply at the same time

Cleaning: The lens needs to be cleaned daily in a high-dust environment, and it is cleaned weekly under general conditions. Similarly, equipment in mixed-age activity areas also requires regular maintenance. Calibration: Every 3 months, the calibration sensitivity of the light source is tested with a standard, and the explosion-proof performance is re-checked every year. The calibration logic in the consolidated accounting statements can be used as a reference. It is forbidden to modify parameters without authorization: adjusting the alarm value is a major hidden danger, and the fault needs to be troubleshoot according to the specifications. This is similar to the technical specifications required for optical detector electrode optimization

Location: Priority is installed at risk points such as the outlet of crushing equipment and the elbow of the conveying pipeline, and the pipeline diameter > 500mm should be installed symmetrically. Avoid high-temperature sources and material impact areas during installation. Angle: The probe is at an angle of 30°-45° between the pipe axis and the elbow is ≥ 1.5 meters. Linkage: It needs to be linked with the fire extinguishing device and emergency shut-off valve, and the response time is ≤ 0.5 seconds. You can refer to the experience of linkage control in the construction of bored piles

Detection type: Solid waste treatment and other scenarios need to choose the "spark + hot particle double detection" model to avoid missed reports. For enclosed spaces such as subways, it can be used with a suction smoke detector to improve reliability. Protection level: IP65 and above protection is required for high-dust environments, and the lens needs to be anti-fog and anti-stick coating. Explosion-proof requirements: flameproof detectors (such as Ex d IIB T6) are required for flammable environments. In explosive atmospheres, precautions for spark discharge from motor bearings also need to be considered.

It is widely used in flammable and explosive environments such as solid waste treatment, petrochemical, textile, and pharmaceutical, especially suitable for working conditions with high dust concentration and complex materials. For example, in wire EDM machining, spark detectors can help monitor abnormal discharges during machining

Spark detectors detect light signals or ionization signals in the air through photoelectric sensors or ionization sensors to determine whether sparks are generated. Once a spark is detected, an alarm is immediately triggered and the fire extinguishing device is linked. In special scenarios such as wind turbines, non-contact spark detectors can monitor spark formation in real time and trigger safety chains and emergency systems
