Abstract
The present invention is a deaeration method for a bubble-containing liquid in which, using the laminar flow phenomenon that occurs when a liquid is made to move into a tube, air bubbles in the laminar flow are enlarged by aggregation and separated by discharge from a discharge opening to remove the bubbles. The dearation method is characterized by comprising the following: a bubble-containing liquid pressure-feed step in which a bubble-containing liquid is pressure fed; a single-layer or multiple-layer circulation pipe flow adjustment step in which the pressure-fed bubble-containing liquid can be subjected to thin-layer flow adjustment to the shape of a circulation pipe; a bubble enlargement step in which air bubbles in the bubble-containing liquid being transported during the aforementioned steps are pressurized by flow adjustment and are caused to flow together and enlarge; an air separation step in which, by constriction and release from a discharge opening, the air bubbles are separated and discharged from the liquid component; and a liquid diffusion step in which the liquid component separated from the air bubbles is made to diffuse in a radial umbrella shape.

叙上の構成に基づいて、作用を説明する。
The operation will be explained based on the above structure.
気泡を混入する含泡液体は、含泡液体供給機構２を経て、供給管１に供給されて、層流形成管体４へ導入される。含泡液体は直ちに含泡液体滞溜部３に入り、外周の間隔ｇに相当する管状層流路機構７に導入され、層流作用を受け、液体内の気泡は互いに隣り合う気泡同士が結合し、拡大されて気液分離吐出口８に達し、ここで間隔ｇがより狭少で絞り効果が働き、含泡液体が圧縮凝集して噴霧吐出される。気体分は液体分より離散し、液体回収貯溜槽１１の開口部１２より大気開放される。液体分は、弧状突出部９によって外方外周に向かって導出され、脱気された状態で傘状の拡散板機構１０に沿って流下し、液体回収貯溜槽１１内に流下し貯溜され、一定量貯溜後、排出口１３より脱気状態の液体を得ることができる。
The bubble-containing liquid mixed with bubbles is supplied to the supply pipe 1 through the bubble-containing liquid supply mechanism 2 and introduced into the laminar flow forming tube 4. The bubble-containing liquid immediately enters the bubble-containing liquid retention part 3 and is introduced into the tubular layer flow path mechanism 7 corresponding to the outer peripheral interval g, and is subjected to laminar flow action. Then, it is enlarged and reaches the gas-liquid separation discharge port 8, where the gap g is narrower and the squeezing effect works, and the foam-containing liquid is compressed and agglomerated and sprayed. The gas component is separated from the liquid component, and is released to the atmosphere from the opening 12 of the liquid recovery storage tank 11. The liquid component is led out toward the outer periphery by the arc-shaped protrusion 9, flows down along the umbrella-shaped diffusion plate mechanism 10 in a deaerated state, flows down and is stored in the liquid recovery storage tank 11, and is constant. After the amount storage, a degassed liquid can be obtained from the discharge port 13.

Then, the outer peripheral portion in a double gap g 1, g 2 a provided tubular layer flow channel mechanism 7a of laminar flow formed tube 4A, 7b is formed, a short time defoamed adapted to a large amount of bubble-containing liquid Can be done efficiently. Since the other mechanism configuration is the same as that of the above-described embodiment, the same reference numerals are given and the detailed description is omitted. Here, the size of the double gaps g 1 and g 2 may be the same or different, and is not limited at all.
なお、上記実施例において、層流形成管体４の長さは長尺であることが好ましく、その長さは何等特定されず、また、同層流形成管体４の断面形状も円形，楕円形は勿論のこと、三角形，四角形などの多角形状について実施できる。

そして、傘状の拡散板機構１０，１０ａ，１０ｂの外周端より流出する脱泡された回収液体は流下状態で液体回収貯溜槽１１内に供給されるものであるが、滴下の場合を避けるため、液体の流下を助ける吊下板（図示せず）を付設して気泡を発生する虞れのある滴下状況の形成を防止することもできる。
The defoamed recovered liquid flowing out from the outer peripheral ends of the umbrella-shaped diffusion plate mechanisms 10, 10a, 10b is supplied into the liquid recovery storage tank 11 in a flowing state, but in order to avoid dripping. In addition, a hanging plate (not shown) that assists the flow of the liquid can be attached to prevent the formation of a dripping situation that may generate bubbles.
