Closed-Loop Solid-Liquid Separation With Gravity-Assisted Heat Exchange

The patent applies parameter changes by precisely controlling the circulation amount of DME within a narrow optimal range. The system monitors and adjusts DME circulation parameters (temperature, pressure, flow rate) to maintain efficient heat exchange while preventing unfavorable liquid phase formation. This resolves the contradiction by dynamically optimizing the operating parameters rather than using fixed high circulation amounts.

The patent resolves this contradiction by implementing precise parameter control within a narrow optimal range. The system continuously monitors DME circulation conditions and adjusts temperature, pressure, and flow rate parameters to prevent gas-liquid two-phase flow while maintaining sufficient circulation for cycle efficiency. This balanced parameter optimization allows the system to achieve both good heat exchange efficiency and acceptable cycle productivity.

The patent introduces an intermediary substance B that circulates in a closed system to transfer heat for DME phase change. Substance B acts as a mediator between the heat source and DME, enabling efficient heat transfer with a compact heat exchanger design. This intermediary approach replaces direct external heat source connection, reducing both device complexity and heat exchanger size while maintaining effective phase change functionality.

The patent utilizes phase transitions of substance B in the closed circulation system to enable latent heat transfer for DME phase change. Instead of using sensible heat from an external source, substance B undergoes phase changes (evaporation and condensation) that provide efficient heat transfer. This phase transition mechanism maintains simplified device configuration while dramatically improving heat exchange efficiency compared to sensible heat approaches.

The patent employs a closed system with flexible sealing mechanisms and enclosed pathways for substance A circulation. The system uses sealed connections and containment structures that prevent substance A from opening to the atmosphere, even as device size increases for higher processing capacity. This sealing approach effectively eliminates substance A emissions while maintaining the scalability needed for increased productivity.
