After comprehensive treatment of the on-site dust, it was tested that the dust collection rate generated by the sand-sprinkling machine in the automatic shell making workshop was ≥98%. After the filter cartridge dust collector + secondary high-efficiency filtration, the dust removal system emission concentration was <1mg/m3, and the clean air after emission returned directly to the workshop, ensuring that the workshop's cold and heat are not lost, and ensuring the energy-saving effect of the constant temperature and humidity workshop.
