ZDA forest wood dust resuspending sampling analysis system Introduction: The forest wood dust resuspension sampling analysis system is the only patent product in China that meets the “Technical Standard for Particle Resuspension Sampling” of the Ministry of Environmental Protection; the sampling of particulate matter adopts the international filter weighing method. Principle function: The forest wood dust resuspension sampling analysis system provides basic data for studying the function of controlling the fog in the forest by measuring the retarding force of air particles in different plant leaves. System composition: Mainly consists of control system, pre-treatment system, resuspension box, air filtration system, cutter, pneumatic control system, which has externally connected components; the pre-treatment system pre-processes the blade samples to suspend the blade particles and send them to resuspension. The box provides samples for collection. Features: 1. It can simulate the experimental process of the absorption and attachment of open source particles by the blade, and complete the sampling of the particle sample of the leaf source sample, which is convenient for the relevant physical and chemical analysis. It is the analysis of forestry assessment of the dustfall and delay of the particulate matter. experiment apparatus. 2. It can carry out cutting sampling with different particle sizes such as TSP, PM10 and PM2.5. The five-channel design, the sampling channel is flexible and variable, can be used as parallel sample, and the sampling module meets the requirements of source spectrum analysis. Technical Parameters: Testing environment: Ambient temperature 5~35°C; relative temperature ≤85% Working power supply: AC220V±10%/50Hz Working power: 1500W Sampling flow range: 0~20L/min; in units of 0.01L/min Sample flow constant current: (16.7 ± 0.25) L / min Sample flow range: 0~5L/min, with 0.01L/min unit Precision thermometer: -10~55°C, minimum division value 0.1°C Humidity meter: 10~100RH%; ±2RH% Evacuation time range: 0-30min, in seconds Pre-test pressure: -40Kpa~0Kpa Atmospheric pressure: (60Kpa~110Kpa) ±0.1Kpa Pumping speed: 0.3m / s, relative change does not exceed ± 5% Noise decibel: ≤65db(A) Sampling method: manual, automatic continuous cycle sampling Sampling time: (10 minutes ~ 999 hours) ± 0.1% Suspension box: 650*920(H)mm Filter: 47mm quartz / Teflon material Main material: stainless steel Surface treatment: Electropolishing
