摘要： A countercurrent liquid-solid contacting apparatus comprises a liquid purifying column for substantially purifying a liquid by passing the liquid upwardly through a bed of purifying material and a regenerating column for regenerating the purifying material used fo purify the liquid. The liquid purifying column includes supply and transfer ports defined respectively at the top and bottom thereof and has therein the bed of purifying material which is spaced a predetermined distance from the top of the liquid treating column to provide a vacant space. The purifying column further includes a liquid inlet and outlet with a portion of the purifying bed above the liquid outlet serving as a settling layer to avoid any possible fluidization and/or expansion of the purifying material. The regenerating column is similar in construction to the construction of the purifying column, however, compressed air and washing liquid are successively or simultaneously supplied into the regenerating column to fluidize the soiled purifying material and separate suspended solids from the soiled purifying particles. The regenerated purifying material is continuously or intermittently supplied into the purifying column. A method therefor is also disclosed.
摘要翻译：逆流液固接触装置包括：液体净化塔，用于通过将液体向上通过净化材料床和用于再生用于净化液体的净化材料的再生塔来基本上净化液体。液体净化塔包括分别位于其顶部和底部的供给和输送口，并且在其中具有与液体处理塔的顶部隔开预定距离的净化材料床，以提供空的空间。净化塔还包括液体入口和出口，其中在液体出口上方的净化床的一部分用作沉降层，以避免净化材料的任何可能的流化和/或膨胀。再生塔在结构上类似于净化塔的构造，然而，压缩空气和洗涤液依次或同时地供应到再生塔中，以使污染的净化材料流化，并将悬浮固体与污染的净化颗粒分离。再生净化材料连续或间歇地供入净化塔。还公开了一种其方法。

摘要： A liquid purification apparatus which comprises a hollow cylindrical column having a liquid rectifier and collector positioned respectively adjacent the bottom and top of the column in communication with liquid inlet and outlet. A mass of adsorbent material is accommodated within the column in such an amount that a portion of the material within the column and above the liquid collector forms a settling layer to avoid any possible fluidization and/or expansion of another portion of the material situated between the liquid rectifier and collector. The column has a material inlet at the top thereof through which material is continuously supplied into the column while a portion of the material adjacent the bottom of the column is exhausted to the outside through an outlet at the bottom of the column. The uppermost surface level of the material within the column is maintained within a predetermined range.
