• Equipped with imported differential pressure transmitter to convert pressure signal and output

  
  

• Equipped with imported light source with color temperature of 2900K, the light source is converted into parallel light beam through the smoke tube through reflector, lens device and focal length adjustment device

  
  

• By imported silicon optical receiver, the optical signal changes into electrical signal and output, data stability, accuracy

  
  

• Equipped with standard filter for optical path system calibration

  
  

• The sampling probe is installed in the sampling pipe of the equipment. The sampling probe is made of stainless steel, which is connected with the sampling pipe through a flange or thread structure and is fixed and sealed. A row of holes are arranged in the center of one side of the sampling control head for sampling, and the sampling holes are away from the direction of wind speed flow to prevent the blockage of combustion dust

  
  

• The sampling probe is connected to the sampling pump through the PP hose to pump the sampling gas to the gas pretreatment system. The sampling pump pumping volume is 36L/Min, working pressure 7 Kg air pressure (0.7mpa) working vacuum degree -93.1kpa, flow rate 36L/Min

  
  

• The gas pretreatment system includes filtration system, gas cooling system, gas dehumidification and drying system and gas regulation system.

  
  

• Equipped with a three-level filter system, the first level filter is used for the cylindrical coarse filter system, used to filter the relatively large particles in the flue gas, prevent the blockage of the pipe and the joint, the filter can be replaced. The secondary filter adopts cup type protection filter, which can filter particles larger than 0.5μm. The filter element device can be replaced. The three-stage filter adopts membrane filter to filter particles larger than 0.2μm.

  
  

• The cooling system is condensed and dehydrated by condenser and peristaltic pump. The condenser has dual cooling, the stable dew point temperature is about 0.1℃, the outlet temperature is about 5℃. The outlet of peristaltic pump is equipped with condensate collecting box with built-in sponge.

  
  

• The dehumidification and drying system uses the air filter tube to place DRIERITE brand anhydrous calcium sulfate for dewatering treatment, and filters the gas moisture to be measured in the air pipe to ensure the drying of the gas entering the analyzer. Anhydrous calcium sulfate can change color after absorbing water, easy observation and easy replacement.
