Title:
AIR DIFFUSION DEVICE AND AIR DIFFUSION METHOD
Document Type and Number:
Japanese Patent JP2015112581
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air diffusion device that has a simple structure and a high efficiency of oxygen dissolution and is easily maintained without an extra load on a blower for supplying air.SOLUTION: Air supplied from air supply means 22 becomes bubbles, which enter a charging case 20 through flow passages 18 of bubbles at a bottom plate 14 of the charging case 20. Shrinking means 12 is installed to make the bubbles charged in the charging case 20 fine. The bubbles is further hindered from rising by a string-like dendritic ring structure branched from a stem. Bubble-rising hindering means made of the stem having a larger diameter than the ring branch hinders the bubbles from rising in the charging case 20 to increase a retention time of the bubbles in the charging case 20. The bubble shrinking means made of the ring branch having a small diameter is able to segment the bubbles as they rise in the charging case 20.
