AI Technical Summary
Existing two-stage gasifier systems are prone to clogging and severe dust pollution when crushing wet coal, making it difficult to control particle size uniformity. Furthermore, they lack efficient and environmentally friendly crushing technology, resulting in low gasification efficiency, high costs, and difficulty in achieving continuous industrial operation.
It adopts a spiral uniform feeding device, atomized humidification and dust removal design and a grate-less screen structure, combined with a spiral feeding mechanism, spray component and crusher, to achieve uniform material conveying and efficient crushing, reduce dust pollution and adapt to various coal types and moisture content fluctuations.
It achieves efficient crushing, reduces environmental pollution, lowers operating costs, improves gas quality and production stability, adapts to different coal types and moisture contents, and reduces the labor intensity of operators.
