On - line Gas Analysis System KGD - MQ - 504 for Industrial Safety

The KGD-MQ-504 on-line gas analysis system is designed for specific working conditions where the sample gas contains dust, moisture, and tar. It consists of three parts: a pretreatment unit, a control unit, and a gas analysis unit.

Based on the non-dispersive infrared (NDIR) gas analysis technology with independent intellectual property rights, it can simultaneously and continuously measure the calorific value of coal gas and biogas on-line, as well as the volume concentrations of gases such as CO, CO₂, CH₄, H₂, O₂, and CₙHₘ, and calculate the calorific value. This is beneficial for improving the utilization efficiency of coal gas, saving energy and reducing consumption, and ensuring the safety of industrial sites.

• Pretreatment Unit: Long service life and stable performance. Straight-tube or steam sampling probes can be selected according to different tar contents to effectively remove tar from the sample gas. A single-stage refrigerator is configured to remove moisture from the sample gas, and two-stage filtration is achieved to ensure long-term on-line operation of the instrument.
• Control Unit: Fully automated detection with simple operation. It is controlled by a PLC program and can automatically complete operations such as changing water in the water scrubber, sampling, and troubleshooting.
• Gas Analysis Unit: Simultaneously measures gas volume concentration and calorific value. The Gasboard-3100 (on-line type) coal gas analyzer with independent intellectual property rights is used for on-line gas analysis and detection. It can simultaneously measure the volume concentrations of multi-component gases such as CO, CO₂, CH₄, H₂, O₂, and CₙHₘ, automatically calculate and display the calorific value of coal gas and biogas, replacing the combustion-type calorific value meter.
• Low maintenance and operation costs. With a 10-inch touch screen, it can monitor and display the system operation status in real-time without the need for manual on-site operation, greatly reducing enterprise costs.
• Intelligent data management. Data can be transmitted to the superior centralized control system through multiple interfaces, providing real-time basis for remote monitoring and adjusting on-site processes.
