LIQUID FEEDING STRUCTURE AND SEPARATION APPARATUS USING IT

摘要

PROBLEM TO BE SOLVED: To provide a liquid feeding structure capable of appropriately changing opening of a feeding port according to fluctuation of a liquid pressure at an upstream side of the feeding port of the liquid fed to a particulate layer. SOLUTION: In the liquid feeding structure, a feeding port formation part 8A is arranged in the state it is abutted on the particulate layer 3b or it is approximately abutted on it and the liquid W2 is fed from the feeding port 8a formed on the feeding port formation part 8A to the particulate layer 3b. The feeding port formation part 8A is constituted such that opening of the feeding port 8a is increased according to increase of the liquid pressure at the upstream side of the feeding port 8a and the opening of the feeding port 8a is reduced according to decrease/restoration of the liquid pressure at the upstream side of the feeding port 8a.
