Abstract: A segmented reactor for hydrothermal synthesis in desulfurization gypsum quality improvement is provided, including a mixing and incubation device and a segmented pressurized reaction device sequentially connected and assembled in that order. The mixing and incubation device includes a premixing reactor equipped with a steam-injection feed inlet and a high-speed stirring and mixing component. The segmented pressurized reaction device includes a pressurized reactor, a material tumbling, dispersing and conveying component, and a steam spray component. The segmented pressurized reactor is provided with a rotatable cylinder defining a primary reaction zone and a residual reaction zone. A distribution density of steam injection nozzles in the primary reaction zone is greater than that in the residual reaction zone.

Abstract: A corrosion-inhibited organic waste supercritical hydrothermal combustion treatment system is provided, which relates to the technical field of harmless treatment of organic waste. To address the severe corrosion issues in existing supercritical hydrothermal combustion treatment systems and the resource waste after treatment, the corrosion-inhibited organic waste supercritical hydrothermal combustion treatment system is provided. Based on meeting the requirements for supercritical hydrothermal combustion of organic waste, the system achieves low-cost mitigation of corrosion in both the preheating and cooling sections of a subcritical zone in the supercritical hydrothermal combustion treatment system by injecting supercritical water and incorporating a hydrogen supply unit. Additionally, the issue of resource waste is resolved through the recovery and reuse of hydrogen within the system.
