GH-601 flue gas pretreatment system

Purpose

The GH-601 flue gas pretreatment system can be used in conjunction with infrared flue gas, ultraviolet differential flue gas, flue gas comprehensive analyzer, and smoke (gas) tester to filter, heat, rapidly condense and reduce fixed pollution source wet flue gas, dehydrate, and automatically discharge condensed water to minimize the adsorption of pipeline condensed water on the measured gas, effectively improve measurement accuracy, and extend the service life of sensors.

Execution standards

HJ/T 47-1999 "Technical Conditions for Smoke Samplers"

HJ 57-2017 "Determination of Sulfur Dioxide in Fixed Source Waste Gas by Potentiometric Electrolysis Method"

Performance characteristics

◆ Equipped with a 5.1-inch wide temperature display screen, displaying Chinese menus with vivid graphics and text for easy operation

◆ Adopting two-stage high-power semiconductor refrigeration, with a cooling rate of ≥ 80NL/h and fast cooling speed, it can ensure that high-temperature gases quickly cool down to the set temperature

The gas path condenser adopts a glass material dual channel design, which quickly condenses and dehydrates, and the dual peristaltic pumps timely discharge the condensed water

◆ Built in automatic cleaning pump, automatic cleaning of pipeline at sampling start and end

Integrated design of sampling tube and heat tracing tube, heating temperature of 120 ℃, uniform temperature, effectively avoiding condensation and adsorption of various chemical components in the flue gas by water vapor inside the sampling tube, independent power supply, independent display of heating temperature, ensuring real-time monitoring of heating temperature

Dual stage filtration: capable of working stably under high dust conditions. High efficiency titanium filter element is installed in the front section of the sampling tube to effectively filter dust and prevent pipeline pollution. The built-in filter is made of tetrafluoroethylene material with a filter hole diameter of ≤ 0.1 μ m, which can effectively remove dust from the flue gas and ensure measurement accuracy

◆ Sample gas inlet and outlet method: stainless steel quick plug connector

◆ Connecting trachea: The connecting trachea made of polytetrafluoroethylene material can effectively prevent the adsorption of SO2 in the trachea

◆ Optional built-in nitrogen oxide converter, high conversion efficiency, improves NOx measurement accuracy
