水清洗对空气净化材料过滤性能的影响

用于空气净化的材料一般为一次性使用,但有的应用场所需要对其进行反复水清洗多次使用。通过实验手段,研究常规涤纶纤维层滤料,在荷尘、清洗、烘干、荷尘等多次反复中其过滤效率、阻力、容尘量的变化情况。实验结果表明,清洗对滤料的过滤效率、阻力和容尘量没有明显的影响,滤料可以通过水清洗的方式反复使用。

Effect of Water Cleaning on Performance of Air Filtration Medias

Air filtration media are designed for disposable,but in some application,it should be used for many times with water cleaning.Through experiments,the performances of polyester fiber layer media,which are cleaned with water for many times,including filtration efficiency,resistance,dust capacity are studied in the paper.It was indicated by the results that water cleaning has less effect on filtration efficiency,resistance and dust capacity of the filter media.Therefore,air filtration media can be used repeatedly by way of water cleaning.
