Abstract: Aiming at the problems of suspension of the adsorbent circulation, disqualification of product, flameout of catalyst regeneration, and removal of fresh raw material, non-disassembly cleaning device was designed and manufactured through studying the selection of impeller type, impeller size and speed, stirring power, stirring bearings, seals, filter elements and their pore sizes according to the internal conditions of the filter at the bottom of the regenerator. This device achieved 100% success rate of on-site application. When the filter is blocked after installation and use of the device, the adsorbent block can be broken by shaking the device. This can lower labor intensity, reduce safety and environmental risks in the processing process, ensure product quality and realize stable production of S Zorb device, saving 80,000 yuan of annual cost.
