Production of stainless steel fume purification | E-purifiers | removal efficiency of wind capacity purification fume purification facilities measuring two cases: (1) installed in the exhaust pipe fume fume purification facility, by simultaneously measured before and after purification fume emission concentration and the amount of wind can be according to the standard formula to calculate body 3.6 soot removal efficiency. (2) installed in the exhaust hood purification facilities, it would take before making efficiency test to determine the occurrence of a stable source of smoke and soot emissions measured concentration and the amount of wind installation and does not install purification facilities, and then the body of the standard 3.6 the calculated soot removal efficiency. Fume sampler technical specifications Accuracy: ± 0.02mg / m Reproducibility: CV% ≤1.8 Operating temperature range: 0 ~ 100 ℃ fume collection efficiency: ≥95% Dimensions: Length 56.00 soil 0.05mm cartridge filter diameter Jane 17.00 0.05mm soil supply voltage: 220V. "Cooking fume emission standards" content is: To implement the "People's Republic of China Air Pollution Prevention Law," cooking fume pollution prevention and control of the atmospheric environment and the living environment, the development of this standard. This standard specifies the maximum allowable emission concentrations and fume purification equipment minimum removal efficiency catering units fumes. This standard is the standard for the trial, since January 1, 2002 implementation. This standard is responsible for the interpretation by the State Environmental Protection Administration.
