POROUS HONEYCOMB FILTER
PROBLEM TO BE SOLVED: To provide a porous honeycomb filter that has sufficient strength to endure practical use and has both low pressure loss and high collection rate.SOLUTION: A porous honeycomb filter 1 includes: a porous first cell wall 21 allowing an exhaust gas to pass therethrough; a second cell wall 22 hardly allowing an exhaust gas to pass therethrough relative to the first cell wall 21; and a cell 3 forming a gas passage that extends while being surrounded by the first cell wall 21 and the second cell wall 22. The second cell wall 22 has porosity that is lower than that of the first cell wall 21.SELECTED DRAWING: Figure 1
【課題】実用に耐えうる十分な強度を有し、低い圧力損失と高い捕集率を兼ね備えることが可能な多孔質ハニカムフィルタを提供すること。【解決手段】排ガスを透過させる多孔質の第１セル壁２１と、第１セル壁２１よりも排ガスを透過しにくい第２セル壁２２と、第１セル壁２１及び第２セル壁２２に囲まれて伸びるガス流路を形成するセル３と、を有する多孔質ハニカムフィルタ１である。第２セル壁２２は、第１セル壁２１よりも気孔率が小さい。【選択図】図１
