AI Technical Summary
In existing technologies, lightweight resin particles remaining in dusty gases during the production of polyvinyl chloride are emitted into the atmosphere, leading to material waste and an increased probability of dust pollution.
A drying and dust removal system is adopted, including a centrifuge tank, centrifuge, dryer, cyclone separator, wet dust removal device and wastewater pool. The light component resin is captured by the wet dust removal device and recycled to the wastewater pool to achieve resource recycling.
It significantly improved the capture rate of light component resins, reduced dust pollution, reduced material loss, and improved economic benefits.
