| Abstract: | The concentrations of volatile organic compounds(VOCs)from fugitive emission of printing equipment including gravure printing with solvent-based ink and flexographic printing with water-based ink were detected.The collection efficiency of VOCs was simulated by computational fluid dynamics(CFD)method.Results showed:(1)the highest mean concentration of non-methane hydrocarbon(NMHC)nearby gravure printing equipment with solvent-based ink reached 5975.67 mg/m3,around 31.2 times of flexographic printing equipment with water-based ink(191.67 mg/m3).Even if water-based ink was used and reduced the release of NMHC,the concentration in operation space might exceed“Occupational exposure limits for hazardous agents in the workplace-Part 1:Chemical hazardous agents”(GBZ 2.1-2019).(2)The design of external collection hood should be established to alleviate the fluctuation of volatile pollution gas concentration in the printing workshop.(3)The simulation of fugitive emission of VOCs by CFD showed that collection hood could effectively reduce fugitive emission of VOCs and its collection efficiency was around 70%-75%. |
