Product overview

      The system can monitor the surface temperature, dust concentration, combustible gas and other data of the coal pile in the closed coal yard in real time to prevent spontaneous combustion. When there are unsafe hidden dangers such as excessive harmful gas in the closed coal yard, it will remind the personnel in the coal yard and the operators in the centralized control room of coal handling, so as to protect the safety of the closed coal yard and operators and the safety and reliability of fire fighting.

       The on-line dust monitoring system shall be able to continuously monitor the coal yard, send an alarm signal locally when the alarm limit is reached, and display the real-time detection dust concentration data and alarm signal on the digital coal yard display screen. The on-line dust monitoring system integrates atmospheric PM2 5. PM10 monitoring and other functions. When the PM value reaches the set upper limit, automatically start the opening of the fog gun system, take atomization spray dust reduction measures for the on-site environment, automatically close the system when the PM value reaches the set lower limit, and reserve the interface as the reserved interface of the digital coal yard system. The coal yard gas monitoring system monitors the concentration of methane, carbon monoxide and other combustible gases in the closed coal yard in real time through instruments. The combustible gas detector shall be set with primary and high alarm limits. When the gas concentration exceeds the standard, the operator shall be reminded to take protection and evacuate the workplace in time.

Construction characteristics

  It can realize real-time online dust and smoke monitoring, with automatic control and audible and visual alarm;

  The detector shall be able to be calibrated regularly to ensure that it accurately reflects the concentration of combustible gas in the coal yard, and the range of alarm parameters shall be adjustable;

  The online monitoring system has the characteristics of fast and accurate measurement, high sensitivity, stable performance and simple maintenance;

  The measurement range of the system meets the explosion-proof safety protection requirements of closed coal yard and the latest national standards;

  The system can establish mathematical model and early warning mechanism according to the on-site detection sensor data, which can be displayed in the form of curve and statistics; The system is linked with the on-site alarm output, and realizes the report statistics, analysis and auxiliary decision-making of monitoring data in the background.
