On - line Gas Analysis System KGD - MQ - 505 Product Introduction The KGD - MQ - 505 on - line gas analysis system is designed for
working conditions with high dust content in the sample gas. It
consists of four parts: a sampling probe, a pretreatment unit, a
control unit, and a gas analysis unit. The system adopts non -
dispersive infrared (NDIR) gas analysis technology with independent
intellectual property rights, which can continuously and
simultaneously measure the volume concentrations and calorific
values of multi - component gases such as CO, CO₂, CH₄, H₂, O₂,
C₂H₂, C₂H₄, and CₙHₘ in real - time. It is applied to the on - line
gas monitoring of process points such as blast furnace gas,
converter gas, coke oven gas, and CDQ circulating gas electric
furnace, which is beneficial for improving the utilization
efficiency of gas, saving energy and reducing consumption, and
ensuring safe production in industrial sites. Product Features - Pretreatment Unit: Long service life and stable performance. It
adopts a stainless - steel, electrically - heated temperature -
controlled dry - type sampling probe, which has a long service life
and high accuracy. The automatic purging technology is used to
solve the problem of probe blockage and ensure the reliability of
the analysis system. 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 sampling, back - flushing, and drainage.
- Gas Analysis Unit: Simultaneously measures gas volume concentration
and calorific value. A 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, C₂H₂,
C₂H₄, and CₙHₘ, automatically calculate and display the calorific
values of coal gas and biomass gas, and can replace the combustion
- type calorific value meter.
- High safety factor, explosion - proof grade Ex d IIC T4 Gb.
- Low maintenance and operation costs: It can monitor the system
operation status in real - time without the need for manual on -
site operation, greatly reducing maintenance 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.
