Gasification Reactor Slag Separation via Nested Funnel Inserts

The quenching space is segmented into multiple functional zones: a spray quenching zone for efficient cooling, an overflow zone with a first funnel-shaped container for initial separation, and a second funnel-shaped insert acting as a separating cone for final particle filtration. This segmentation allows the system to achieve both efficient cooling and effective particle retention.

The patent introduces water as an intermediary substance that serves multiple functions: it absorbs heat from hot reaction products during spray quenching, forms a cooling bath for continued heat transfer, and acts as a medium through which slag particles are separated via overflow flow. The water bath thus mediates between the hot reaction products and the cooling system while enabling particle retention.

The patent employs a nested structure where a second funnel-shaped insert (separating cone) is placed inside the first funnel-shaped container, both situated within the water bath. This nested arrangement creates multiple overflow edges at different levels, forming a multi-stage separation system that effectively retains slag particles while maintaining a relatively compact overall structure.

The patent utilizes vertical dimensionality by creating overflow edges at different heights: the first funnel-shaped container has an overflow edge, and the nested second funnel-shaped insert has its own overflow edge positioned at a different level. This vertical arrangement of overflow edges creates a multi-level separation system that enhances particle retention capability without significantly increasing horizontal space requirements.
