【発明の属する技術分野】
この発明は、特に液体と気体の2つの流体を効率よく混合するもので、液中に10ミクロン以下の泡を混合し、殺菌水や酸素水等を製造できるエジェクター装置に関するものである。
【0002】
【従来の技術】
従来の技術として、1つの流体を流入させる複数の通路を有するノズル部と、これに相対する複数の通路を有する混合部を、相対する各通路が同軸心状にそれぞれ合致すべく対向して配し、他の1つの流体を導入する孔を有する吸入室を前記ノズル部と混合部の相互間に配設して、相対する各通路が吸入室を介して連通すべく成り、先方部に複数の通路から成る混合部を穿設して本体とし、該本体の反対側の手前部を開口し混合部に向かって穿設した嵌合洞部の混合部に通じる懐部を吸入室として確保して胴側壁に導入孔を穿設し、該嵌合洞部に複数の通路を穿設せるノズル部を嵌入して相対する各通路を合致させ任意の固定手段により結合して成ると共に、前記混合部は、通路の一部または全部を、通路全域またはその対向口部の内径を、相対するノズル部通路またはその対向口部の内径よりも0.8〜2.0mm大きく形成して成るエジェクター装置がある。(特許文献1参照)

【0004】
【発明が解決しようとする課題】
しかし、上記のような形態では、吸引容量と吸引真空度を高めるため、1つの流体の圧入流量を大きくし、それに応じて他の1つの流体の吸引容量および吸引真空度を高めようとしているが、吸入室を複数のノズル部と混合部の相互間に配設しているため、高馬力高負圧のポンプ等が必要となる。
また、通路全域またはその対向口部の内径を、相対するノズル部通路またはその対向口部の内径よりも1mm程度大きく形成してなるが、大き過ぎて、逆に吸引真空度が低下するのではないかと思われる。
【0005】
本発明は、上記の問題点に鑑みなされたもので、その目的は、吸気側の利用は、気圧低下の低温沸騰や真空容器容器内の気圧をさげ、気化熱による急速温度低下並びに、真空梱包機への応用により、食品加工工場の効率向上。
排気側では、液中に10ミクロン以下の泡を大量かつ遠距離まで送ることができ、水中の溶存酸素濃度を高めると共に、水中の不純物の除去、オゾンガスの応用で水の殺菌や水にオゾンを溶かし殺菌水の製造、活魚等の運搬車両への積載等で幅広く利用できる、高負圧エジェクターを提供するものである。
【0006】
上記課題を解決するために本発明のエジェクター装置は、円筒状のノズル本体と、ノズル本体の後部内に挿入配置され、前方に向かって細くなる円錐台状の流入孔が中央部に形成され、外面が円筒状で内面が流入孔の円錐台状の内面に連続して円錐台状に形成された放出部が前方に突出して形成された吸気ノズルと、ノズル本体の前部内に吸気ノズルの放出部の前端面と隙間を空けて挿入配置され、前方に向かって広くなる円錐台状の排出孔が中央部に形成され、外面が及び内面が円筒状の流入部が後方に突出して形成された排気ノズルと、吸気ノズルの前端側と排気ノズルの後端側とで形成されたドーナツ状の空間に連通してノズル本体に設けられた吸気継ぎ手と、中央部に流通孔が形成され、吸気ノズルの後部に連通して設けられた配管連結部を備えてなり、吸気ノズルの放出部の前端面と排気ノズルの流入部の後端面との隙間が1mmから2mmに設定され、排気ノズルの流入部の内径が吸気ノズルの放出部の前端における内径より0.2mmから0.3mm大きく設定され、排気ノズルの排出孔の円錐台状の内面はその延長が排気ノズルの流入部の後端における吸気ノズルの放出部の前端における内径に相当する点を通るように形成されていることを特徴としている。
【0007】
【発明の実施の形態】
本発明の実施の形態を図に基づいて説明する。1は、エジェクター装置で、吸気ノズル2、排気ノズル3、ノズル本体4、吸気継ぎ手4a及び配管連結部5を備えている。吸気ノズル2は、ノズル本体4の後部内に挿入配置され、前方に向かって細くなるテーパー状すなわち円錐台状の流入孔2aが中央部に形成され、外面が円筒状で内面が流入孔2aの円錐台状の内面に連続してテーパー状すなわち円錐台状に形成された放出部2bが前方に突出して形成されている。排気ノズル3は、ノズル本体4の前部内に吸気ノズルの放出部2bの前端面と隙間Sを空けて挿入配置され、前方に向かって広くなる円錐台状の排出孔3aが中央部に形成され、外面が円筒状で内面がフラット状すなわち円筒状の流入部3bが後方に突出して形成されている。ノズル本体4は、各図に示されるように、両端が開放した円筒状で、吸気ノズル2の前端側と排気ノズル3の後端側とでドーナツ状の空間Kが形成されている。吸気継ぎ手4aは,この空間Kに連通してノズル本体4に設けられている。配管連結部5は、中央部に流通孔5aが形成され、吸気ノズル2の後部に連通して設けられている。なお、排気ノズルの排出孔3aの円錐台状の内面は、図6に拡大して示されているように、その延長が排気ノズルの流入部3bの後端における吸気ノズルの放出部2bの前端の内径に相当する点を通るように形成されている。
【0008】
吸気ノズルの放出部2bの前端面と排気ノズルの流入部3bの後端面との間に吸気継ぎ手4aから吸い込まれる気体を流入させるために、隙間S1mmから2mmに設定されている。また、排気ノズルの流入部3bの内径3b1が吸気ノズルの放出部2bの前端における内径2b1より0.2mmから0.3mm大きく設定されている。
【0009】
上記エジェクター装置1の使用例について下記に述べる。
ポンプPの吸水口P1に吸水管Bを取り付け、水槽に接続、若しくは挿入する。
つぎに、ポンプPの排出口P2に送水管Cを取り付け、水槽内に固定若しくは置き、循環型の水槽JSを形成する。
なお、配管類はホースでも代用可能である。
送水管Cを水槽JS内で水没させ、途中若しくは先端にエジェクター装置1を取り付ける。
また、ポンプ容量でエジェクター装置1を、複数取り付け可能である。
つぎに、エジェクター装置1の吸気継ぎ手4aに、チューブT若しくは、配管類を繋ぎ、空気やオゾン(オゾン発生器O)を吸気できるよう、水槽JSの外に設ける。
この状態でポンプPを作動させることにより、水Mが吸水管Bを通りポンプPに吸い込まれポンプPの排出口P2より、水Mが送水管Cを通りエジェクター装置1に送られる。
送られた水Mは、吸気ノズル2で絞られ圧力を増し、流速を高め水柱Hとなって排気ノズル3の中央を高速で通過する。
その際、排気ノズル3の中で中央を通過する水柱Hと周辺の静止水との間に摩擦がおき、負圧が生じ、逆流水Gが発生し、排気ノズル3内に逆流するに従い、急速に流速を高め、逆流水Gと水柱Hの隙間SMに、より強い摩擦が生じ高い真空が発生し、発生した真空を水平な隙間HSに集中させることで高負圧を発生する。
そして、高負圧を発生した、隙間HSに隙間Sから気体O(周囲の空間Kより)を自吸させ、隙間SMに入り逆流水Gと、水柱Hと隙間SMの真空で微細に曝気させ、微細な泡Aが発生し、排気ノズル3から放出される。
その際、水柱Hが慣性を保ち続ける距離だけ微細な泡Aは、水平に移動し続ける。
例えば、水槽JSで水柱Hが慣性を保ち続け縦の回転対流を連続的に起こし続ければ、水槽JS内の水は、乳白色に変化し、10ミクロン以下の泡Aのため、水面には泡立たない。
【0010】
上記のように排出ノズル3から放出された10ミクロン以下の微細な泡Aの単位体積当たりの気泡表面積が大きいため、酸素やオゾンOが溶けやすく、泡Aは、電気的に帯電しており、水中の不純物や浮遊物に対し付着性を持つ。
また、吸気量及び吸気圧は制御バルブの具備(図示せず)で、制御は容易に行うことができる。
【0011】
また、本発明は高負圧をも発生する。
高負圧の使用例では、吸気継ぎ手4aにチューブT若しくは配管を接続するだけで容易に負圧が取り出せ、実験では150Wのポンプ、締め切り圧70kpaのポンプで−98.1kpaの負圧を発生し、密封容器の使用により常温で水が沸騰する。
【0012】
さらに、他の実験結果を下記に述べる。
(1)、本発明のエジェクター装置で、巾2m長さ3m深さ2mの12mの水槽が5分程度で泡が行き渡り、1時間程度で溶存酸素の飽和状態に至り、水槽内が乳白色に変化し、魚介類やプランクトンの育成に多大な効果を有する。
(2)、オゾンガスの使用により、殻付生牡蠣の殺菌処理を行った結果、10ミクロン以下の泡の中で20時間育成した牡蠣の細菌数は実験前、E.coli(MPN/100g)は1530で細菌数(個/g)124000であったが、殺菌処理をした結果、E.coli(MPN/100g)は230で細菌数は500と生食用の適応基準まで殺菌した。
(3)、オゾンガスの使用により、殻付生牡蠣の小型球形ウィルス(SRSV)の殺菌処理実験を行った結果、殺菌機未使用は陽性反応が出たが、殺菌機使用は陰性と結果が出た。
但し、牡蠣自体の生体の問題で摂取した物が排出されるまで20時間以上必要で、短時間でもウィルスの膈膜は破壊している可能性は大であるが、遺伝子が排出されるまで検査結果としては陽性反応が出ることがある。
(4)、本発明の高負圧発生のエジェクター装置で発生した、電気的に帯電した10ミクロン以下の微細な泡が、水中の微細な浮遊物や不純物に付着し水面まで浮上させ、それを取り除くことで水質の浄化や環境が改善できた。
【0013】
上記各実施例において、エジェクター装置の大きさ及び数量ならびにポンプ能力は、水槽の体積や負圧使用量に合わせ、適時選択することができる。
【0014】
【発明の効果】
(1)、本発明は、吸気側の利用は、気圧低下の低温沸騰や真空容器容器内の気圧をさげ、気化熱による急速温度低下並びに、真空梱包機への応用により、食品加工工場の効率向上。排出側では、液中に10ミクロン以下の泡を大量かつ遠距離まで送ることができ、水中の溶存酸素濃度を高めると共に、水中の不純物の除去。オゾンガスの応用で水の殺菌や水にオゾンを溶かし殺菌水の製造、活魚等の運搬車両への積載等で幅広く利用できる。
(2)、放出部の内径より流入部の内径を0.2mmから0.3mm大きくすることにより、吸引真空度を一層高めることができる。
(3)、隙間を1mmから2mmにすることにより、空気やオゾン等の気体と、水等の混合率(濃度)を飛躍的に向上させることができる。
(4)、10ミクロン以下の泡を6m以上水平方向に送れるものである。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 denotes an ejector device which includes an intake nozzle 2, an exhaust nozzle 3, a nozzle body 4, an intake joint 4a, and a pipe connecting portion 5. The intake nozzle 2 is inserted and arranged in the rear part of the nozzle body 4, and has a tapered or frustoconical inflow hole 2a which is tapered toward the front. The outer surface is cylindrical and the inner surface is the inflow hole 2a. A discharge portion 2b formed in a tapered shape, that is, a truncated cone shape, is formed so as to protrude forward from the inner surface of the truncated cone shape. The exhaust nozzle 3 is inserted and disposed in the front portion of the nozzle body 4 with a clearance S from the front end face of the discharge portion 2b of the intake nozzle, and a frustoconical discharge hole 3a widening toward the front is formed in the center portion. The inflow portion 3b having a cylindrical outer surface and a flat inner surface, that is, a cylindrical shape, protrudes rearward. As shown in each figure, the nozzle body 4 has a cylindrical shape with both ends open, and a donut-shaped space K is formed between the front end side of the intake nozzle 2 and the rear end side of the exhaust nozzle 3. The intake joint 4 a communicates with the space K and is provided in the nozzle body 4. The pipe connecting part 5 is provided with a flow hole 5 a in the center and is communicated with the rear part of the intake nozzle 2. Note that, as shown in an enlarged view of FIG. 6, the inner surface of the truncated cone shape of the exhaust hole 3a of the exhaust nozzle is extended to the front end of the discharge portion 2b of the intake nozzle at the rear end of the inflow portion 3b of the exhaust nozzle. It is formed so as to pass through a point corresponding to the inner diameter.
[0008]
The gap S is set to 1 mm to 2 mm so that the gas sucked from the intake joint 4a flows between the front end surface of the discharge portion 2b of the intake nozzle and the rear end surface of the inflow portion 3b of the exhaust nozzle . The inner diameter 3b1 of the inflow portion 3b of the exhaust nozzle is 0.3mm larger set from 0.2mm than the inner diameter 2b1 at the front end of the discharge portion 2b of the intake nozzle.
[0009]
An example of use of the ejector device 1 will be described below.
The water suction pipe B is attached to the water suction port P1 of the pump P, and is connected to or inserted into the water tank.
Next, the water supply pipe C is attached to the discharge port P2 of the pump P, and fixed or placed in the water tank to form a circulation type water tank JS.
In addition, a hose can be substituted for piping.
The water pipe C is submerged in the water tank JS, and the ejector device 1 is attached to the middle or the tip.
Further, a plurality of ejector devices 1 can be attached with a pump capacity.
Next, a tube T or piping is connected to the intake joint 4a of the ejector apparatus 1 so that air and ozone (ozone generator O) can be sucked out of the water tank JS.
By operating the pump P in this state, the water M is sucked into the pump P through the water absorption pipe B, and the water M is sent from the discharge port P2 of the pump P to the ejector device 1 through the water supply pipe C.
The sent water M is squeezed by the intake nozzle 2 to increase the pressure, increase the flow velocity, and become a water column H, and passes through the center of the exhaust nozzle 3 at high speed.
At that time, friction occurs between the water column H passing through the center in the exhaust nozzle 3 and the surrounding still water, negative pressure is generated, the backflow water G is generated, and as the backflow flows into the exhaust nozzle 3, The flow rate is increased, a higher friction is generated in the gap SM between the backflow water G and the water column H, and a high vacuum is generated. A high negative pressure is generated by concentrating the generated vacuum in the horizontal gap HS.
Then, the gas HS (from the surrounding space K) is caused to self-suck into the gap HS where the high negative pressure is generated, and enters the gap SM to be finely aerated by the backflow water G and the vacuum of the water column H and the gap SM. Fine bubbles A are generated and discharged from the exhaust nozzle 3.
At that time, the fine bubbles A continue to move horizontally by the distance that the water column H keeps the inertia.
For example, if the water column H keeps inertia in the tank JS and continues to cause vertical rotation convection continuously, the water in the tank JS turns milky white and does not foam on the water surface because of bubbles A of 10 microns or less. .
[0010]
Since the bubble surface area per unit volume of the fine bubbles A of 10 microns or less discharged from the discharge nozzle 3 as described above is large, oxygen and ozone O are easily dissolved, and the bubbles A are electrically charged, Adhesive to underwater impurities and suspended solids.
Further, the intake air amount and the intake air pressure can be easily controlled by providing a control valve (not shown).
[0011]
The present invention also generates a high negative pressure.
In the high negative pressure use example, the negative pressure can be easily taken out simply by connecting the tube T or the pipe to the intake joint 4a. In the experiment, a negative pressure of -98.1 kpa is generated with a pump of 150 W and a pump of 70 kpa of deadline pressure. By using a sealed container, water boils at room temperature.
[0012]
Further, other experimental results are described below.
(1), in the ejector apparatus of the present invention, it spreads bubbles in width 2m length 3m depth 12m 3 aquarium 2m about 5 minutes, leading to saturation of dissolved oxygen in about 1 hour, the milky water tank It has a great effect on the growth of seafood and plankton.
(2) As a result of sterilization of shelled raw oysters by using ozone gas, the number of bacteria of oysters grown in bubbles of 10 microns or less for 20 hours was E. E. coli (MPN / 100 g) was 1530 and the number of bacteria (cells / g) was 124000. E. coli (MPN / 100 g) was 230 and the number of bacteria was 500, which was sterilized to the adaptation standard for raw food.
(3) As a result of the sterilization treatment experiment of small spherical virus (SRSV) of shelled raw oysters by using ozone gas, a positive reaction appeared when the sterilizer was not used, but a negative result was obtained when the sterilizer was used. It was.
However, it takes 20 hours or more until the ingested food is discharged due to a problem with the body of the oyster itself, and it is highly possible that the capsule of the virus has been destroyed even in a short time, but it is inspected until the gene is discharged. As a result, a positive reaction may occur.
(4) The electrically charged fine bubbles of 10 microns or less generated in the ejector apparatus generating high negative pressure of the present invention adhere to fine suspended matters and impurities in the water and float to the water surface. By removing it, water quality purification and environment could be improved.
[0013]
In each of the above embodiments, the size and quantity of the ejector device and the pump capacity can be selected in a timely manner according to the volume of the water tank and the amount of negative pressure used.
[0014]
【The invention's effect】
(1) According to the present invention, the use on the intake side reduces the low-temperature boiling of the pressure drop and the pressure inside the vacuum container, and the rapid temperature drop due to the heat of vaporization and the application to the vacuum packaging machine, the efficiency of the food processing factory Improvement. On the discharge side, a large amount of bubbles of 10 microns or less can be sent into the liquid to a long distance, and the dissolved oxygen concentration in the water is increased and impurities in the water are removed. The application of ozone gas can be widely used for sterilizing water, dissolving ozone in water, manufacturing sterilized water, and loading live fish on transport vehicles.
(2) The suction vacuum degree can be further increased by increasing the inner diameter of the inflow part by 0.2 mm to 0.3 mm from the inner diameter of the discharge part.
(3) By setting the gap to 1 mm to 2 mm, the mixing ratio (concentration) of a gas such as air or ozone and water can be drastically improved.
(4) A bubble of 10 microns or less can be sent in the horizontal direction by 6 m or more.
