The dust, temperature, combustible gas and toxic and harmful substances produced in the process of coal processing and production in coal washery and coal shed project have the possibility of organic gas leakage. In order to ensure the safety of production, the project carries out inspection, early warning and corresponding emergency treatment for dust, temperature, combustible gas and toxic and harmful gases, and these gases leak or diffuse into the air, It will do harm to workers, equipment and environment, and even cause property loss or casualties. In order to meet the requirements of current chemical industry development, safety production and environmental protection, and occupational health management department's safety requirements for chemical industry, it is suggested to install toxic and harmful gas alarm and temperature dust gas alarm detectors.
In this situation,Bus monitoring host and online bus gas alarm probe can be used.
The 485 series bus type gas detection and alarm system adopts non-standard protocol or Modbus protocol for data acquisition and transmission. The intelligent transmitter node collects and detects the gas concentration on site, and the host patrols each node to monitor the gas concentration change on site in real time with intelligent background software. Bus mechanism is adopted, with strong anti-interference ability, convenient layout and simple wiring. At the same time, the intelligent transmitter node also provides a switch output that can control external devices (exhaust fan, solenoid valve, etc.). The detector detects gas concentration by natural diffusion and adopts imported sensor, which has good sensitivity and excellent repeatability; The instrument adopts embedded micro control technology and has high reliability.
The shell of the detector is made of cast aluminum with high strength, temperature resistance and corrosion resistance. This product is suitable for testing the concentration of toxic, harmful, flammable and explosive gases in the ambient air. It is widely used in metallurgy, power plants, chemical industry, mines, tunnels, tunnels, underground pipelines and other places to effectively prevent accidents.
