本考案は、たとえばごみ焼却炉の調温塔などのように、微粒化液体（水）を噴 霧媒体（空気）により微粒化して噴霧し、排ガスの温度を下げる時に用いる二流 体噴射ノズルに関する。 The present invention relates to a two-fluid injection nozzle used for reducing the temperature of exhaust gas by atomizing atomized liquid (water) by an atomizing medium (air) and spraying it, such as in a temperature control tower of a refuse incinerator.
【０００２】[0002]
従来の二流体噴射ノズルたとえば空気・水噴射ノズルを図９に基づいて説明す る。 A conventional two-fluid jet nozzle, for example, an air / water jet nozzle will be described with reference to FIG.
【０００３】 １は軸心Ｃに沿って配置された空気ノズル筒で，空気室１ａに連通する空気噴 射口１ｂが軸心位置に形成され、その先端面が空気噴射口１ｂに向かって先尖り となるテーパー面１ｃに形成されている。２は空気ノズル筒１に水室２ａを介し て同心状に外嵌された水ノズル筒で、先端側でテーパー面１ｃとの間に混合水路 ３ａを形成するテーパー状の絞り筒３を介して、先端側軸心位置に混合室４ａを 形成する混合筒４が接続されている。水ノズル筒２の側面には水室２ａ内に水を 供給する水供給口２ｂが形成されるとともに、水室２ａと混合水流路３ａの間で 水室２ａを閉止するリング状絞り部２ｃに、対称位置２箇所に絞り孔２ｄが形成 されている。さらに、混合筒３の先端部端板３ｂには先端側が外側に広がる複数 の噴射孔５が周方向一定間隔毎に形成されている。Reference numeral 1 is an air nozzle cylinder arranged along the axis C, and an air ejection port 1b communicating with the air chamber 1a is formed at the axial center position, and its tip end face is directed toward the air ejection port 1b. It is formed on the tapered surface 1c which is sharp. Reference numeral 2 denotes a water nozzle cylinder that is concentrically fitted onto the air nozzle cylinder 1 via a water chamber 2a, and a tapered throttle cylinder 3 that forms a mixed water channel 3a between the tip end side and the tapered surface 1c. A mixing tube 4 forming a mixing chamber 4a is connected to the tip end side axial center position. A water supply port 2b for supplying water into the water chamber 2a is formed on the side surface of the water nozzle cylinder 2, and a ring-shaped throttle portion 2c for closing the water chamber 2a is provided between the water chamber 2a and the mixed water flow passage 3a. The diaphragm holes 2d are formed at two symmetrical positions. Further, a plurality of injection holes 5 whose tip ends are spread outward are formed in the tip end plate 3b of the mixing cylinder 3 at regular intervals in the circumferential direction.
【０００４】[0004]
しかし、上記構成の空気・水噴射ノズルは、空気噴射口１ｂからの空気と、混 合水路３ａからの水が混合されてから噴射孔５に至るまでの距離が長いことから 、混合室４ａ内で混合攪拌された空気・水混合流体が再び分離され、微細化が不 十分となって噴射口５から噴霧される粒子径が大きくなる傾向があった。また、 噴射方向によっては粒子径の大きいものが噴射されることがあり、むらがあった 。 However, in the air / water injection nozzle having the above-described configuration, since the distance from the air from the air injection port 1b and the water from the mixing water passage 3a to the injection hole 5 is long, the inside of the mixing chamber 4a There was a tendency that the air-water mixed fluid that had been mixed and stirred in (1) was separated again, and the atomization became insufficient and the particle size sprayed from the injection port 5 became large. Also, depending on the direction of injection, particles with a large particle size may be injected, resulting in unevenness.
【０００５】 本考案は、上記問題点を解決して、容量が大きくても粒子径を充分に小さくし 、均一な噴霧が実現できる二流体噴射ノズルを提供することを目的とする。An object of the present invention is to solve the above-mentioned problems and to provide a two-fluid injection nozzle capable of realizing a uniform spray by sufficiently reducing the particle diameter even if the capacity is large.
【０００６】[0006]
上記問題点を解決するために本考案の二流体噴射ノズルは、軸心方向に噴霧媒 体を供給する噴霧媒体噴射孔が接続されるとともに周囲に複数の微粒化液体噴射 孔が接続された衝突室と、この衝突室の先端側にオリフィス板を介して配置され た略半球状の分配室と、この分配室の先端球面側で放射方向に形成された複数の 噴射孔とを具備し、前記衝突室の外形を分配室より小径に形成するとともに、前 記オリフィス板のオリフィス孔を衝突室から分配室に向かって拡径される円錐状 に形成し、分配室のオリフィス孔近傍に複数の混合用透孔が形成されたミキシン グプレートを設けたものである。 In order to solve the above-mentioned problems, the two-fluid injection nozzle of the present invention has a collision in which a spray medium injection hole for supplying a spray medium in the axial direction is connected and a plurality of atomized liquid injection holes are connected in the periphery. A chamber, a distribution chamber of a substantially hemispherical shape disposed on the tip side of the collision chamber via an orifice plate, and a plurality of injection holes radially formed on the tip spherical side of the distribution chamber, The outer shape of the collision chamber is smaller than that of the distribution chamber, and the orifice holes of the orifice plate are formed in a conical shape that expands from the collision chamber toward the distribution chamber. It is provided with a mixing plate having through holes.
【０００７】[0007]
上記構成によれば、衝突室で噴霧媒体流に微粒化液体が衝突されて噴霧媒体中 に微粒化され、オリフィス孔から分配室に送られて混合されてすぐに噴射孔から 外方に噴出されるので、従来のように空気・水混合流体が再び分離されて粒子径 が増大するようなことはない。しかも、ノズルの容量が大きくなるに従って分配 室および衝突室の径も大きくなり、衝突のエネルギーを損失して粒子の微粒化が 阻止されたり噴射力が低下しがちであるが、本考案では衝突室を小径に構成し衝 突室からオリフィス板のオリフィス孔を介して緩やかに拡径して分配室に送り込 むので、衝突室のエネルギーを損失することなく分配室に移送でき、さらに分配 室でミキシングプレートにより混合して噴射孔より噴射するので、容量が大きく なっても、小容量時の微粒化特性を維持またはさらに向上させて均一な噴霧を実 現することができる。 According to the above configuration, the atomized liquid is collided with the atomizing medium flow in the collision chamber to be atomized into the atomizing medium, sent to the distribution chamber through the orifice hole, mixed, and immediately ejected outward from the injection hole. Therefore, unlike the conventional case, the air-water mixed fluid is not separated again and the particle size is not increased. Moreover, as the capacity of the nozzle increases, the diameters of the distribution chamber and the collision chamber also increase, and the energy of collision tends to be lost and atomization of particles tends to be blocked or the injection force tends to decrease. Since it is configured to have a small diameter and is gradually expanded from the collision chamber through the orifice hole of the orifice plate and sent to the distribution chamber, the energy in the collision chamber can be transferred to the distribution chamber without loss, and further, in the distribution chamber. Since the mixture is mixed by the mixing plate and is injected from the injection hole, even if the volume becomes large, it is possible to maintain or further improve the atomization characteristics at the time of a small volume and realize uniform spraying.
【０００８】[0008]
以下、本考案に係る空気・水噴射ノズルの実施例を図１〜図８に基づいて説明 する。 Hereinafter, an embodiment of an air / water injection nozzle according to the present invention will be described with reference to FIGS.
【０００９】 まず、従来の空気・水噴射ノズルを改善した基本例を図７および図８に基づい て説明する。１１は本体１２の正面で軸心Ｃ位置に円柱状に形成された衝突室で 、その軸心Ｃ位置には空気供給口１３から衝突室１１内に軸心Ｃ方向に沿って空 気（噴霧媒体の一例）を噴射する空気噴射孔１４が形成されるとともに、その外 周部には水供給口１５から衝突室１１内に軸心Ｃに対して直角方向（図５）また は傾斜（図４）するように水（微粒化液体の一例）を噴射する水噴射孔１６が周 方向一定間隔毎に複数個（図面では２個）形成されている。１７は本体１２の前 部に装着される先端部材で、軸心位置に衝突室１１に連通して衝突室１１と同一 径の半球状の分配室１８が軸心Ｃ位置に形成され、そして先端球面側に放射方向 に複数の噴射孔１９が形成されている。First, a basic example in which the conventional air / water injection nozzle is improved will be described with reference to FIGS. 7 and 8. Reference numeral 11 denotes a collision chamber that is formed in a cylindrical shape at the axial center C position in front of the main body 12. At the axial center C position, air (spray) is introduced from the air supply port 13 into the collision chamber 11 along the axial center C direction. An air injection hole 14 for injecting a medium) is formed, and an outer peripheral portion of the air injection hole 14 extends from the water supply port 15 into the collision chamber 11 in a direction perpendicular to the axis C (Fig. 5) or inclined (Fig. 4) As described above, a plurality of (two in the drawing) water injection holes 16 for injecting water (an example of atomized liquid) are formed at regular intervals in the circumferential direction. Reference numeral 17 denotes a tip member that is attached to the front part of the main body 12. A hemispherical distribution chamber 18 having the same diameter as the collision chamber 11 is formed at the axis C position so as to communicate with the collision chamber 11 at the axial center position. A plurality of injection holes 19 are formed in the radial direction on the spherical surface side.
【００１０】 上記基本例において、水噴射孔１６から噴射された水は、衝突室１１内で空気 噴射孔１４から噴射される空気流に衝突して微粒化され攪拌されつつ分配室１８ に送られ、すぐに分配室１８から噴射孔１９を介して外方に噴霧される。このよ うに、噴射孔１９の近傍で空気と水が混合され分配室１８での移動距離が短いの で、再分離されて粒子径が大きくなることがなく、安定した微粒体を噴霧するこ とができる。In the above basic example, the water injected from the water injection hole 16 collides with the air flow injected from the air injection hole 14 in the collision chamber 11 and is atomized and sent to the distribution chamber 18 while being stirred. Immediately, it is sprayed outward from the distribution chamber 18 through the injection hole 19. In this way, since air and water are mixed in the vicinity of the injection hole 19 and the moving distance in the distribution chamber 18 is short, it is possible to spray stable fine particles without re-separation and increase in particle size. You can
【００１１】 しかし、上記ノズルでは、ノズルの容量が大きくなると、分配室１８の径が大 きくなるに伴って衝突室１１の径も大きくする必要がある。すると、衝突室１１ の容量が大きくなるに従って衝突のエネルギーが失われやすくなり、微粒化が阻 害されることになる。次の実施例では、基本例の問題点を解決して、容量が大き くなっても微粒化が阻害されることがない空気・水噴射ノズルを提供するもので ある。However, in the above-mentioned nozzle, as the capacity of the nozzle increases, the diameter of the collision chamber 11 needs to increase as the diameter of the distribution chamber 18 increases. Then, as the capacity of the collision chamber 11 increases, collision energy is more likely to be lost, and atomization is hindered. The following example solves the problems of the basic example, and provides an air / water injection nozzle that does not hinder atomization even if the capacity increases.
【００１２】 すなわち、図１および図２に示すように、分配室１８の容量が大きくなっても 、衝突室１１の容量をそれ程増加させず、そして衝突室１１で衝突された混合流 体の衝突エネルギーを損失させることなく分配室１８に導くために、本体１２と 先端部材１７の間にオリフィス板２１を介装し、衝突室から分配室１８側に緩や かに広がるオリフィス孔２２を介在させている。これにより、大容量のノズルで あっても、衝突室１１でのエネルギー損失を少なくして水を高効率で微粒化し、 そのエネルギーを損失することなく分配室１８に移動させ、さらに速やかに噴射 孔１９から噴射させることができる。また、分配室１８には、オリフィス孔２２ 側近傍に複数の混合用透孔２３ａが形成されたミキシングプレート２３が配設さ れ、オリフィス孔２２から圧送される混合流体を、混合用透孔２３ａ通過させる ことにより再度混合して微粒化するとともに粒子分布を均一化するように構成さ れている。したがって、噴射孔１９から噴霧する粒径を微粒化すると共にむらな く全周囲にわたって均一な粒径の噴霧をすることができる。That is, as shown in FIGS. 1 and 2, even if the volume of the distribution chamber 18 becomes large, the volume of the collision chamber 11 is not increased so much, and the collision of the mixed fluid collided in the collision chamber 11 occurs. In order to guide the energy to the distribution chamber 18 without loss, an orifice plate 21 is interposed between the main body 12 and the tip member 17, and an orifice hole 22 that gently expands from the collision chamber to the distribution chamber 18 side is interposed. ing. As a result, even with a large-capacity nozzle, the energy loss in the collision chamber 11 is reduced, the water is atomized with high efficiency, the energy is moved to the distribution chamber 18 without loss, and the injection holes are made more quickly. It can be jetted from 19. A mixing plate 23 having a plurality of mixing through holes 23a formed in the vicinity of the orifice hole 22 side is arranged in the distribution chamber 18, and the mixed fluid pumped from the orifice hole 22 is mixed with the mixing through hole 23a. By passing it, it is mixed again and atomized, and the particle distribution is made uniform. Therefore, it is possible to atomize the particle size sprayed from the injection hole 19 and to spray the particle size uniformly over the entire circumference.
【００１３】 なお、この空気・水噴射ノズルでは、水噴射孔１６は軸心Ｃに対して直交する 方向に衝突室１１に噴射するように形成している。 上記基本例によれば、たとえば水の流量が50リットル/h、空気の流量が10Nm3/h の 場合、得られる噴霧の平均粒径は70〜75μｍであったが、容量を大きくして水の 流量が500 リットル/h、空気の流量が100 Nm3/h とした場合、噴霧の平均粒径は95〜 105 μｍと粗くなる傾向が見られた。これに対して図１の実施例では、水の流量 が500 リットル/h、空気の流量が100 Nm3/h とした場合の噴霧の平均粒径は、68〜70 μｍと基本例の小容量時より小径で、さらに粒子径の分布範囲も狭い優れた噴霧 状態を実現することができた。In this air / water injection nozzle, the water injection hole 16 is formed so as to inject into the collision chamber 11 in a direction orthogonal to the axis C. According to the above basic example, for example, when the flow rate of water is 50 liters / h and the flow rate of air is 10 Nm 3 / h, the average particle size of the obtained spray was 70 to 75 μm. When the flow rate was 500 liter / h and the air flow rate was 100 Nm 3 / h, the average particle size of the spray tended to become coarse, 95 to 105 μm. On the other hand, in the embodiment of FIG. 1, when the flow rate of water is 500 liter / h and the flow rate of air is 100 Nm 3 / h, the average particle size of the spray is 68 to 70 μm, which is a small volume of the basic example. It was possible to achieve an excellent spray state with a smaller diameter than before and a narrow particle size distribution range.
【００１４】 なお、オリフィス板２１のオリフィス孔２２は、図３に示すように入口側の拡 径比が大きい球面状オリフィス孔２２Ａや、図４に示すように出口側の拡径比が 大きいラッパ状状オリフィス孔２２Ｂに形成してもよい。また、混合用透孔２３ ａは図２に示すように直状に形成したが、図５に示すように外広がりとなる傾斜 状混合用透孔２３ｂ、あるいは図６に示すように外窄まりとなる傾斜状透孔２３ ｃを複数個形成してもよい。The orifice hole 22 of the orifice plate 21 is a spherical orifice hole 22A having a large expansion ratio on the inlet side as shown in FIG. 3 or a trumpet having a large expansion ratio on the outlet side as shown in FIG. It may be formed in the circular orifice hole 22B. Further, although the mixing through hole 23a is formed in a straight shape as shown in FIG. 2, the inclined mixing through hole 23b is widened outward as shown in FIG. 5 or the external constriction is shown as shown in FIG. A plurality of inclined through holes 23 c may be formed.
【００１５】[0015]
以上に述べたごとく本考案の二流体噴射ノズルによれば、分配室に入る前の衝 突室を絞り、微粒液体と噴霧媒体との衝突のエネルギーを失わずに混合した後、 漸次拡径されるオリフィス孔から分配室に送られ、さらにミキシングプレートの 混合用透孔により再混合させそしてすぐに噴射孔から外方に噴出されるので、従 来のように空気・水混合流体が再び分離されて粒子径が増大するようなこともな く、衝突室を小径に構成し衝突室からオリフィス板のオリフィス孔を介して緩や かに拡径して分配室に送り込むので、衝突室のエネルギーを損失することなく分 配室に圧送して再混合するので、容量が大きくなっても、粒子径も小さくその分 布範囲も狭い微粒化特性に優れた噴霧状態を実現することができる。したがって 、たとえば燃焼ガスなどの冷却用等に適した噴霧状態を得ることができる。 As described above, according to the two-fluid injection nozzle of the present invention, the collision chamber before entering the distribution chamber is squeezed and mixed without losing the energy of collision between the fine particle liquid and the atomizing medium, and then gradually expanded in diameter. Is sent from the orifice hole to the distribution chamber, and is re-mixed by the mixing through hole of the mixing plate and immediately jetted outward from the injection hole, so that the air-water mixed fluid is separated again as in the conventional case. The particle size of the collision chamber does not increase, and the collision chamber is constructed with a small diameter and the diameter of the collision chamber is gradually expanded through the orifice holes of the orifice plate and fed into the distribution chamber. Since it is pumped to the distribution chamber without loss and is remixed, even if the volume becomes large, it is possible to realize a spray state in which the particle size is small and the distribution range is narrow, with excellent atomization characteristics. Therefore, for example, it is possible to obtain a spray state suitable for cooling combustion gas and the like.
