Back Scattering Based Dust Monitor

31 

It is an self-developed on-line dust monitoring device, which uses the mainstream technology of laser back scatter measurement with imported core components. It is mainly used for continuous monitoring of various sources emissions of particulate matter concentrations. it can be equipped with CEMS, used alone or several together or form a dust monitoring network with a shared data acquisition and processing unit.

Technical Principle

Dust monitor consists of optical section, circuit and control section, calibrator and purge system.

The laser beam (650 nm) comes across the detection area and produces scattered light after effect with dust particles. The back-scattered light crosses the lens converges into photosensitive detector. Analyzer circuit and control section converts light signal into signal output which is proportional to the dust concentration, and obtains dust particles emission concentration of pollution.

  • Patented reigned zero and span calibration functions
  • Large-screen display and infrared remote control
  • Perfect laser protection
  • Temperature compensation and automatic gain control

 

Applications:

Apply to the monitoring and control of soot emission and flue gas desulfurization and application of power generation boilers, industrial furnaces, industrial boilers in the thermal power, iron and steel metallurgy, petrochemical, chemical, cement, ceramics, waste incineration.
