Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 石炭灰のゼオライト化処理におけるスラリー 状のゼオライト生成物の脱液処理に際し、フィルターの 目詰まりを解消して工程を安定化すること。 【構成】 脱液器からのろ液戻し管に分岐管を設け、こ の分岐管から苛性ソーダろ液を貯蔵タンク内のスラリー 状ゼオライトに添加配合して、スラリー濃度を最適濃度 に維持する。 【効果】 スラリー濃度を一定に維持できるので、脱液 状態を最良状態に維持できる。脱液器のフィルターバッ グの目詰まりを解消できるので、フィルターバッグの寿 命が延長する。 (57) [Summary] [Objective] To eliminate the clogging of the filter and to stabilize the process during the deliquoring process of the zeolite product in the slurry state in the zeolite formation process of coal ash. [Structure] A branch pipe is provided in a filtrate return pipe from the dewatering device, and caustic soda filtrate is added to and blended with the slurry-like zeolite in the storage tank from the branch pipe to maintain the slurry concentration at an optimum concentration. [Effect] Since the slurry concentration can be maintained constant, the deliquored state can be maintained in the optimum state. The filter bag of the drainer can be cleared of clogging, extending the service life of the filter bag.
