Introduction to the MSE-S600 Bus-type Spark Detection System

1 System Introduction

The MSE-S600 series spark detection system uses high-sensitivity spark detectors to accurately identify spark signals and quickly upload them to the spark alarm controller; the spark detection alarm controller analyzes and processes the spark signals, completing the alarm function, activating sound and light alarms, and starting extinguishing devices, with reserved alarm output interfaces for linking with other equipment.

The extinguishing device uses high-pressure inert gas for extinguishing, with gas pipes laid on-site connected to carbon dioxide cylinders. The spark detection alarm controller controls the activation of the extinguishing device to achieve automatic spark extinguishing, with a gas pressure requirement greater than 6kg/cm2.

The spark alarm controller adopts a centralized management approach to achieve unified management of multiple groups of detectors, enabling independent management of each group of detection and extinguishing systems and minimizing execution time through independent group detection control.

The spark detection alarm controller displays real-time detection and status information for each group of detectors, centrally shown on the human-machine interface, and controls the alarm and extinguishing times for each group of detectors. The controller also has a historical record function, allowing users to view alarm and operation records at any time.

The production workshop is an explosion-proof environment, and all selected equipment must meet the explosion-proof requirements on-site.

The MSE-S600-12A series pipeline spark detection alarm extinguishing system effectively captures infrared rays emitted by ignition sources (sparks) in the pipeline through spark probes installed on the walls of the conveying pipeline. An extinguishing device is installed at a corresponding distance (based on the conveying speed of dust or materials); when the control system detects a spark, the alarm unit quickly activates the extinguishing device, and the high-pressure, high-flow atomizing nozzle extinguishes the ignition source (spark) while issuing an alarm notification, with the entire process taking only a few microseconds. The specially designed high-pressure anti-blocking nozzle has precise spray angles and atomization effects, ensuring that the extinguishing medium covers the entire pipeline without requiring large amounts of spray. The extinguishing of sparks does not affect your pipeline, dust removal, filter screens, and other equipment. Additionally, the uniquely designed high-pressure anti-blocking nozzle effectively prevents material blockage of the spray holes. The same extinguishing module can be used in other industries for extinguishing. For example, in the metal processing industry, nitrogen or carbon dioxide can be used for spark extinguishing. After the spark is extinguished, the system automatically stops the extinguishing operation. The entire process requires no manual intervention or operation and does not interrupt your production operations, meeting your continuous production needs. The system also has linkage output points (relay normally open or normally closed contacts), maximizing compatibility with existing PLCs and dust removal fan controllers for subsequent linkage measures. Due to the strong penetration ability of infrared rays, our equipment can accurately detect sparks even in very dirty environments.

5 Spark Detector Product Introduction

The MSE-T3 spark detector is installed on the wall of the conveying pipeline, effectively capturing the infrared rays emitted by sparks in the pipeline. Even if the sparks are hidden in dense materials, the spark detector can sensitively capture the sparks. The spark detector has the following advantages:

1. Sensitive detection. Based on the study of the characteristic spectral curves of various sparks, corresponding high-speed photosensitive components are selected to match the detection wavelength range. The probe can detect the smallest sparks and hot particles, with high sensitivity; at the same time, the detection system can penetrate high-density materials and dust for detection.

2. Uses photoelectric detection technology. Non-contact detection does not interfere with the detected object and will not affect the normal production process; it also has advantages such as high sensitivity, good stability, low power consumption, and long lifespan, making it suitable for industrial-grade continuous operation.

3. Wide-angle detection design. Only two probes are needed to completely cover the pipeline.

4. Sturdy shell. The probe shell is made of aviation aluminum and stainless steel, lightweight and sturdy, resistant to oxidation and corrosion. Combined with specially designed waterproof grooves and sealing rings, the overall shell achieves an IP67 protection level, suitable for harsh outdoor environments. The eye-catching outer red (yellow) coating makes it easy to identify the detection point.

5. Quick installation. The probe installation uses special connectors, making installation very easy; one person can complete the installation of a probe in just a few minutes.
