Principle and configuration of activated carbon desulfurization value measuring instrument
Activated carbon desulfurization value measuring instrument / active carbon desulfurization value measuring device model: DP-8
Scope of application
The activated carbon desulfurization value tester is designed and produced according to the requirements of the national standard GB / T 30202.4-2013 "Test Methods for Coal-based Granular Activated Carbon for Desulfurization and Denitrification Part 4: Desulfurization Value. Activated carbon desulfurization value refers to the quality of desorption of sulfur dioxide at high temperature after the adsorption of sulfur dioxide per unit mass of activated coke saturated under certain conditions. The desulfurization value tester of coal granular activated carbon for desulfurization and denitrification is suitable for the measurement test of the desulfurization value of coal granular activated carbon, as well as the measurement test of the desulfurization value of other types of activated carbon.
2. {Measurement principle
Use the pretreated sample to adsorb the mixed gas of sulfur dioxide, water vapor, oxygen and nitrogen under certain conditions. When the sulfur dioxide is saturated and adsorbed, pass nitrogen gas for analysis. According to the amount of sulfur dioxide desorption, calculate the desulfurization value of active coke.
3. Components:
Activated carbon desulfurization value measuring instrument is composed of gas source, mixed gas supporting system including SO2, O2, N2, water vapor insulation system, adsorption and desorption system, program temperature increasing system, air tightness inspection system, water vapor concentration measurement system, SO2 concentration adjustment control System, desorption volume chemical reaction processing system and mixed control system
