超声波和中空纤维含浸液膜结合脱除气体中二氧化硫的装置及方法
摘要：
本发明公开了一种超声波和中空纤维含浸液膜结合脱除气体中二氧化硫的装置。该装置在中空纤维膜组件(3)周围设有夹套(1)，沿夹套(1)纵向两侧设置超声换能器(2)，超声换能器为列阵排列，其间距为0－100mm。本发明还公开了一种实施该装置的方法，在超声波的作用下，用含有柠檬酸盐溶液的中空纤维含浸液膜吸收含有二氧化硫的气体。吸收后的柠檬酸盐溶液用于制备高浓度二氧化硫气体，循环后的柠檬酸盐溶液用于超声波含浸液膜吸收二氧化硫。使用该装置及方法，比常规的填料吸收和中空纤维含浸液膜吸收具有吸收深度高，二氧化硫脱除率高的特点。
摘要（英）：

The present invention discloses device and method for eliminating SO2 from gas with combined ultrasonic wave and hollow fiber containing soaked film. The device has hollow fiber assembly, sandwiched jacket around the assembly, ultrasonic transducers set longitudinally along the sandwiched jacket and arranged in an array with interval of 0-100 mm. The method includes absorbing SO2-containing gas with hollow fiber containing citric acid solution soaked film, preparing high concentration SO2 gas with the absorbed citric acid solution, and the reuse of the citric acid solution. Compared with conventional technology, the present invention has the features of great absorption depth and high SO2 eliminating rate.
