Advantages of Continuous Smoke and Dust Concentration Monitoring System

Composed of a transmitting and receiving unit, as well as a flue gas pretreatment module, it measures the flue gas in the constant temperature measuring tankThe dust concentration in the flue gas is obtained, and the flue gas pretreatment module consists of a sampling probe, a jet pump, a heating unit, a pressure and temperature control unit, and a constant temperature control unitThe temperature measuring tank and other components are used to extract the sample gas from the flue and heat it up to a temperature above the dew point of the flue gas through a heating device,Then send it to the constant temperature measuring pool for measurement.

The exhaust gas from the pre-treatment module is returned to the flue through the sampling probe. The required jet air and blow air are generated by the clean fan unit, and the blow airUsed to clean the optical components of the smoke detector, ensuring long-term reliable operation of the system.

Advantages of Continuous Smoke and Dust Concentration Monitoring System

Measuring principle

Using the principle of forward scattering to test the scattered light intensity of particles, through specific methodsThe algorithm outputs the concentration of smoke and dust.The embedded high stability laser signal source passes through a constant temperature measurement cell, irradiates smoke particles, and the irradiated smoke particles reflect the laser signal. The reflected light intensity is proportional to the smokeThe dust concentration is directly proportional.

The receiving unit and the transmitting unit receive smoke signals at a specific forward scattering angle to obtain*Sensitivity of detection.

System Features

Ultra low range, small range (0-5) mg/m3, high sensitivity, low detection limit of 0.05 mg/m3.

The instrument adopts various excellent technologies. Including: noise cancellation technology, laser emission power stabilization technology, extremely low noise TIA, interference control and signal integrity design, providing fast, reliable and accurate quantitative smoke emission data.

◆ Automatic calibration technology, achieving zero and full-scale automatic calibration.

Using jet technology to extract some flue gas from the flue, the structure is compact, the installation is simple, the cost is low, and the maintenance is small.
