针对现有脱硫系统中过滤机存在的能耗高、含水率高、稳定性差等问题,根据立盘过滤机的工作原理和恒压过滤的特点,提出了一种预留层过滤方法,通过对中心轴、扇形板、自搅拌系统进行改进,设计一种石膏专用过滤机.应用结果表明,石膏专用过滤机满足脱硫系统的要求,具有很好的节能效果.
In view of the problems of the filter in present desulfurization system about high energy consumption, high moisture of product and poor stability, based on the working principle of the disc filter and the features of constant-pressure filtration, the paper proposed a method of filtering via reserved layer, and designed a filter specially used for plaster filtration after modifying the central shaft, fan-shaped plate and autogeneous mixing system. Application results showed the filter specially used for plaster filtration met the requirements of the desulfurization system with excellent energy-saving effects.
