    • PURPOSE: A pervaporation apparatus for concentrating hydrofluoric acid waste solution and a method thereof are provided to highly concentrate hydrofluoric acid waste solution and to reuse the concentrated hydrofluoric acid waste solution in acid pickling of steel, thereby decreasing environmental load of IT industry and creating added value. CONSTITUTION: A pervaporation apparatus for concentrating hydrofluoric acid waste solution comprises a tank(10), a supply line(40), a pervaporation membrane module(20), a warm air supply part(30), a recollection part(60), and an emission part(50). The tank stores the hydrofluoric acid waste solution. The supply line supplies the stored waste solution to the pervaporation membrane module. The pervaporation membrane module separates moisture from the supplied solution by filtering. The warm air supply part supplies warm air to the said pervaporation membrane module. The recollection part recollects the concentrated solution not having passed through the pervaporation membrane module to the tank. The emission part emits the air supplied to the said pervaporation module to the outside.
    • 目的:提供一种用于浓缩氢氟酸废液的渗透蒸发装置及其方法,以高浓缩氢氟酸废液,并将浓缩的氢氟酸废液再利用于钢酸酸洗,从而降低IT行业的环境负荷,创造附加值 。 构成:用于浓缩氢氟酸废液的渗透蒸发装置包括罐(10),供应管线(40),渗透蒸发膜组件(20),暖空气供应部分(30),回收部分(60)和 发射部分(50)。 储罐储存氢氟酸废液。 供应线将储存的废液提供给渗透蒸发膜组件。 渗透蒸发膜组件通过过滤将水分与所提供的溶液分离。 暖气供应部件向所述渗透蒸发膜组件供应暖空气。 回收部分将没有通过渗透蒸发膜组件的浓缩溶液记录到罐中。 排放部分将供给到所述渗透蒸发模块的空气排放到外部。
