旋回流型濾過器

[Problem] To prevent damage and wear of anti-corrosion materials even in the case of mixed water with a high ion concentration such as seawater containing gravel and sand grains as contaminants. provide utensils. A corrosion-resistant material block is provided outside the filter element, and a contaminant collision prevention member is provided on the surface of the corrosion-resistant material block on the upstream side of the swirling flow. The anti-corrosion material blocks are arranged in two rows in the circumferential direction of the side surface, and eight blocks are arranged in one row. The anti-collision member is L-shaped and arranged so that one surface faces the upper surface of the swirling flow and the other surface is located between the anticorrosive material block and the surface of the filter element. [Selection drawing] Fig. 4【課題】礫や砂粒を夾雑物として含む海水などのイオン濃度の高い混合水の場合であっても、防蝕防止の防蝕材の損傷・磨耗を防止できる濾過エレメントの寿命を延ばした旋回流型濾過器を提供する。【解決手段】濾過エレメントの外側に防蝕材ブロックを配設するとともに、防蝕材ブロックの旋回流上流側の面に夾雑物の衝突防止部材を配設した。防蝕材ブロックは、側面の周方向に2列、1列に8個配設されている。衝突防止部材はL字状で一面が旋回流上面側に、他の面は防蝕材ブロックと濾過エレメント表面の間になるように配設されている。【選択図】図4
