摘　　要：空气颗粒物过滤材料作为一次性使用的耗材,在阻力升高至一定值时就被更换并抛弃,不仅使过滤系统成本增加,而且会产生二次污染,不利于生态环保。通过实验探究滤料清洗再生的方法,研究了MES表面活性剂浓度、温度、清洗时间对清洗效果的影响。结果表明:温度为25℃、MES溶液质量分数为0.7%、清洗时间为30 min时的清洗效果最佳,清洁度可达97%,结合超声波辅助时可使清洁度增至99.2%,经过4次清洗再生后,滤料的阻力、效率与纤维力学性能未发生明显变化,证明了该方法在工业应用中的可能性。As a disposable consumable,filtering material will be replaced and discarded when the resistance rises to a certain value,which not only increases the cost of the filtering system,but also generates secondary pollution,and is not conducive to green ecology.In this paper,the effects of MES surfactant concentration,temperature,and cleaning time on the cleaning effect are investigated by experimentally exploring the cleaning and regeneration methods of filter materials.The results show that the cleaning effect is best with temperature of 25℃,MES solution of 0.7%,and cleaning time of 30 min,and the cleanliness reach 97%.When combined with ultrasonic assistance,the cleanliness will be increased to 99.2%.Moreover,the resistance,efficiency,and fiber mechanical properties of the filter material did not change significantly after 4-cycle of cleaning regenerations,which proved the possibility of the method in industrial applications.
