新型纤维滤芯过滤特性实验研究

Experimental Study on Filter Properties of New Fiber Elements

采用多次通过实验法对新型玻璃、化学纤维滤芯的过滤特性进行对比实验研究。结果表明:尺寸及滤材对滤芯的过滤特性有一定影响,新型玻纤滤芯比新型化纤滤芯具有更优的过滤特性,达到相同极限压降时,新型玻纤滤芯所用时间更长,流阻特性更好,纳污容量更多,φ50 mm的新型玻纤滤芯纳污容量为14. 3 g,同样尺寸的新型化纤滤芯纳污容量为13. 4 g;在所选污染物颗粒精度实验范围内,新型玻纤滤芯平均过滤比为1 000左右,新型化纤滤芯平均过滤比为800左右,最终过滤效率都能达到99. 9%。在该实验条件下,φ50 mm的新型玻纤滤芯的过滤特性最优。

The filtration properties of the new glass and chemical fiber elements were comparative experimental studied by using the multi-pass test method. The results show that the size and filter have a certain influence on the filter properties of the filter. The new type of glass fiber element has better filtration properties than the new chemical fiber element. When the same limit pressure is reached, the new type of glass fiber element is longer and the flow resistance is more better, more pollutant capacity, with Ф50 mm new glass fiber element capacity of 14.3 g, the same size of the new chemical fiber element capacity of 13.4 g. Within the experimental range of selected pollutant particles, the average ratio of glass fiber element is 1000 or so, the average filtration ratio of new chemical fiber element is about 800, the final filtration efficiency can reach 99.9%. Under the experimental conditions,Ф50 mm new glass fiber element filtration properties are the best.
