| Abstract |
Workers working indoors in a building have a problem with health threats caused by secondary pollutants in the factory environment, as well
as fine dust pollutants. Among them, paint over-spray factories with more than 7,000 small-scale paint and coding booths in korea emit
polycarbonate and volatile pollutants. Therefore, in this study, to improve the indoor air quality in a small-scale paint over-spray factory, a
pollutant removal system (FLCS-IAQ; Facility Life Care System Indoor Air Quality) for removing thinner and volatile organic compounds
was proposed based on IoT sensor technology. As a result of conducting CFD simulation and VOCs removal test for chamber and AC unit
installed inside the system for the technical suitability of the system, it was found that two pollutant particles such as VOCs are possible. As
a result of removal of VOCs based on demonstration test, particle collection efficiency was the highest and 93% VOCs removal efficiency
was shown when the ratio of paint aerosol and sorbent supply was set at 1:1. VOCs inlet concentration was 140 ppm and outlet
concentration was about 10 ppm, and the average VOCs removal of about 93% was confirmed during the test. In the future, it is expected
that additional research on the installation location and number depending on the scale of the paint over-spray factory will be possible, but it
is also possible to expand the indoor air pollution pattern and ventilation equipment according to the working pattern, and also to the
painting for the interior site. |
