钛过滤片透过能力恢复的研究

Study on Recoverability of Permeability of Titanium Filter

摘要:

研究了被炭粒子堵塞的钛过滤片透过能力的恢复方法。将堵塞程度平均为55%和95%的两组钛过滤片,用超声清洗和重铬酸钾洗液浸泡不同时间,然后测试其透过性能的恢复效果,证明钛过滤片被炭粒子堵塞的程度、处理方法、洗液配方及处理时间对透过性能的恢复能力都有影响。超声波处理的效果最好,而且滤片被堵塞的程度越小,透过能力越容易恢复。

Abstract:

A recoverable method for permeability of the titanium filter blocked by carbon particles is investigated. Two groups of the samples with the average blockage degree of 55% and 95%, respectively, are cleaned by supersonics or immersed in K_2Cr_2O_7 lotion. The recoverable permeability of these filter are determined later. The test demonstrates that the blockage degree, treating process, lotion formulation and the treating time all have impacts on the recoverability of permeability of titanium filter. It is shown that the treatment by supersonics has the best result, and the less the blockage by carbon particles, the easier for the recovery of the permeability of titanium filter.
