Description

유체 흡입 및 혼합장치{Apparatus for sucking and mixing fluids}Apparatus for sucking and mixing fluids

본 발명은 유체 흡입 및 혼합장치에 관한 것으로, 보다 상세하게는 혼합 효율을 향상시키고 균일하게 혼합될 수 있도록 하는 유체 흡입 및 혼합장치에 관한 것이다. The present invention relates to a fluid suction and mixing device, and more particularly, to a fluid suction and mixing device for improving mixing efficiency and enabling uniform mixing.

종래에는 서로 다른 종류의 제1유체를 흡입하여 제2유체를 혼합하기 위해서 이젝터(ejector)와 이덕터(eductor)를 사용하였다. Conventionally, an ejector and an eductor are used to suck different types of first fluid and mix the second fluid.

일례로, 약품 혼화 공정에서는 소정 약품을 이덕터를 통해 원수에 분사시켜 약품과 원수가 접촉되며 혼합되도록 하였다.For example, in the chemical mixing process, a predetermined chemical is sprayed into the raw water through an eductor so that the chemical and the raw water are contacted and mixed.

그러나, 종래의 믹싱 이덕터는 단일 분사노즐에 의해 유체가 분사되어 축대칭 이차원적 유동을 근간으로 하기 때문에 균일하게 혼합되지 않을 뿐만 아니라, 분사된 유체가 효율적으로 확산되지 않아 혼합 효율도 낮은 문제점이 있었다.However, the conventional mixing eductor is not uniformly mixed because the fluid is injected by a single injection nozzle and is based on an axisymmetric two-dimensional flow, and the injected fluid is not efficiently diffused, so the mixing efficiency is low. .

도 1을 참조하면, 본 발명의 일실시예에 따른 유체 흡입 및 혼합장치(100)는, 제1유체가 내부에서 유동하는 배관(101)과, 배관(101)의 내측면에 둘레방향을 따라 설치되어 제2유체를 분사하는 노즐부(130)를 포함한다. Referring to FIG. 1 , a fluid suction and mixing device 100 according to an embodiment of the present invention includes a pipe 101 through which a first fluid flows therein, and an inner surface of the pipe 101 along the circumferential direction. It is installed and includes a nozzle unit 130 for spraying the second fluid.

배관(101)은 제조가 용이하고 내부식성/내구성이 양호한 PVC재질로 형성될 수 있으며, 제1유체가 내부에서 유동할 수 있도록 유동공간이 마련된다.The pipe 101 may be formed of a PVC material that is easy to manufacture and has good corrosion resistance/durability, and a flow space is provided so that the first fluid can flow therein.

또한, 배관(101)은 노즐부(130)로 제2유체를 이송하도록 일측이 관통된 관통부(101a)가 형성되고, 제2유체가 유입되는 이송배관(미도시)이 연결될 수 있도록 소켓(110)이 구비된다.In addition, the pipe 101 has a through part 101a having one side penetrated so as to transport the second fluid to the nozzle part 130, and a socket (not shown) through which the second fluid is introduced can be connected. 110) is provided.

본 발명에서는 배관(101) 내부를 유동하는 제1유체에 제2유체를 혼합하기 위해 배관(101)의 내측면의 둘레방향에 노즐부(130)를 설치한다.In the present invention, the nozzle unit 130 is installed in the circumferential direction of the inner surface of the pipe 101 in order to mix the second fluid with the first fluid flowing inside the pipe 101 .

노즐부(130)는 도 3에 도시된 바와 같이, 링형으로 형성되는데 제2유체가 유동되는 공간을 형성하도록 단면의 형상이 대략 'ㄷ'자형으로 형성된다. 즉, 배관(101)의 중앙을 향하는 면은 닫힌 형상을 가지며, 배관(101)의 외측을 향하는 면에 개구부가 형성된다. 이러한 노즐부(130)가 배관(101) 내측면에 맞닿도록 장착되면 상기 개구부가 배관(101) 내측면에 의해 닫히면서 유동 공간이 형성되게 된다.As shown in FIG. 3 , the nozzle unit 130 is formed in a ring shape, and the cross-sectional shape is approximately 'C'-shaped to form a space in which the second fluid flows. That is, the surface facing the center of the pipe 101 has a closed shape, and an opening is formed on the surface facing the outside of the pipe 101 . When the nozzle unit 130 is mounted to be in contact with the inner surface of the pipe 101 , the opening is closed by the inner surface of the pipe 101 to form a flow space.

여기서, 노즐부(130)는 일례로 용접에 의해 배관(101)의 내측면에 설치될 수 있으며, 이 경우 노즐부(130)와 배관(101)이 만나는 접촉부 둘레에는 용접부(135)가 형성된다. 다른 예로서, 노즐부(130)는 접착제에 의해 배관(101) 내측면에 설치될 수도 있다.Here, the nozzle part 130 may be installed on the inner surface of the pipe 101 by welding, for example, and in this case, a welding part 135 is formed around the contact part where the nozzle part 130 and the pipe 101 meet. . As another example, the nozzle unit 130 may be installed on the inner surface of the pipe 101 by an adhesive.

본 발명의 실시예에서 노즐부(130)는, 도 1 및 도 3에 도시된 바와 같이, 제1유체가 유입되는 방향(화살표 방향으로 제1유체가 유입됨)의 모서리부(133)는 라운드지게 형성되어 배관(101) 내에서의 제1유체가 원활하게 유동될 수 있도록 구성될 수 있다. In the embodiment of the present invention, as shown in FIGS. 1 and 3 , the corner part 133 of the nozzle part 130 in the direction in which the first fluid flows (the first fluid flows in the arrow direction) is round. It can be configured to be formed so that the first fluid in the pipe 101 can flow smoothly.

또한, 노즐부(130)은 제1유체에 대해 와류발전기(Vortex Generator) 역할을 하여 제1유체가 노즐부(130)을 넘어가면서 혼합 효과(mixing effect)를 보다 크게 할 수 있는 난류 강도(turbulent intensity)를 크게 하는 효과가 있을 수 있다.In addition, the nozzle unit 130 serves as a vortex generator for the first fluid, and as the first fluid passes over the nozzle unit 130 , a turbulent flow strength that can increase the mixing effect. intensity) can be increased.

제1유체가 유입되는 방향에 수직으로 형성된 도 1에 도시된 노즐부(130)의 하부면은, 필요에 따라서는 경사지도록 형성되어 모퉁이부를 제거함으로써 유입되는 제1유체에서 발생될 수 있는 데드존(dead zone)을 최소화할 수도 있다. 이러한 경사면은 동일한 이유로 노즐부(130)의 상부면에도 적용될 수 있다.The lower surface of the nozzle unit 130 shown in FIG. 1 formed perpendicular to the direction in which the first fluid flows is formed to be inclined if necessary, and a dead zone may be generated from the flowing first fluid by removing the corners. (dead zone) can also be minimized. Such an inclined surface may also be applied to the upper surface of the nozzle unit 130 for the same reason.

본 발명의 유체 흡입 및 혼합장치(100)는 노즐부(130)를 통해 분사되는 제2유체가 배관(101)에 유동되는 제1유체에 효과적으로 혼합될 수 있도록 도 1에 도시된 바와 같이, 배관(101)의 내측면에 대해 제1경사각(θ1)으로 경사지게 형성된 분사홀(131)이 구비된다. As shown in FIG. 1 , in the fluid suction and mixing device 100 of the present invention, the second fluid injected through the nozzle unit 130 can be effectively mixed with the first fluid flowing in the pipe 101 , the pipe The injection hole 131 formed to be inclined at a first inclination angle θ1 with respect to the inner surface of 101 is provided.

경사 분사홀(131)을 통해 분사된 제2유체는 도 3에 도시된 바와 같이 소정 지점에서 수렴되는데, 일례로 노즐부(130)로부터의 이격거리(D)는 배관(101) 직경의 1 내지 2배 사이에서 분사된 제2유체가 수렴되도록 분사홀(131)이 경사지게 형성될 수 있다. 이러한 조건을 만족시키도록 분사될 경우, 혼합이 안정화될 수 있을 만큼의 적절한 시간 동안 혼합될 수 있기 때문에 혼합 효율이 향상되며 결과적으로 빠른 시간 내에 효과적으로 혼합된다.The second fluid injected through the inclined injection hole 131 converges at a predetermined point as shown in FIG. 3 . For example, the separation distance D from the nozzle unit 130 is 1 to 1 of the diameter of the pipe 101 . The injection hole 131 may be formed to be inclined so that the second fluid injected between the two times converges. When sprayed to satisfy these conditions, mixing efficiency is improved because mixing can be performed for an appropriate time enough for mixing to be stabilized, and as a result, it is effectively mixed within a short time.

일반적으로 사용되는 배관(101)의 직경을 고려하여 전술된 조건에 만족하는 경사각을 산출해보면, 제1경사각(θ1)은 대략 10도 내지 25도의 범위로 형성되는 것이 바람직하다. When calculating the inclination angle satisfying the above-described conditions in consideration of the diameter of the generally used pipe 101, the first inclination angle θ1 is preferably formed in a range of approximately 10 degrees to 25 degrees.

또한, 본 발명의 복수개의 분사홀(131)은 도 2에 도시된 바와 같이, 링형의 노즐부(130)에 일정한 간격으로 이격 배치되어 균일하게 유체가 혼합될 수 있도록 구성된다.In addition, as shown in FIG. 2 , the plurality of injection holes 131 of the present invention are spaced apart from each other at regular intervals in the ring-shaped nozzle unit 130 so that the fluids can be uniformly mixed.

특히, 본 발명의 일실시예에서 따른 분사홀(131)은, 3차원적으로 분사되어 분사된 제2유체가 소용돌이치며(whirling) 유동될 수 있도록 전술된 제1경사각(θ1)으로 경사질 뿐만 아니라, 도 4에 도시된 바와 같이 배관(101)의 중심(C)에 대해 제2경사각(θ2)으로 경사지게 형성될 수 있다. In particular, the injection hole 131 according to an embodiment of the present invention is not only inclined at the above-described first inclination angle θ1 so that the injected second fluid can swirl and flow three-dimensionally. Instead, as shown in FIG. 4 , it may be formed to be inclined at a second inclination angle θ2 with respect to the center C of the pipe 101 .

이와 같이, 본 발명에 따른 분사홀(131)은 제1경사각(θ1) 및 제2경사각(θ2)을 동시에 구비할 경우, 제2유체가 복수의 분사홀(131)들을 통해 3차원적으로 회전되며 높은 난류 강도(turbulent intensity)를 얻을 수 있게 된다. 그 결과, 분사홀(131)을 통해 분사된 제2유체와 배관(101)을 통해 유입되는 제1유체는 혼합 효율이 극대화되며 빠른 시간내에 혼합될 수 있게 된다.As described above, when the injection hole 131 according to the present invention has the first inclination angle θ1 and the second inclination angle θ2 at the same time, the second fluid rotates three-dimensionally through the plurality of injection holes 131 . and high turbulent intensity can be obtained. As a result, the mixing efficiency of the second fluid injected through the injection hole 131 and the first fluid flowing through the pipe 101 is maximized and can be mixed within a short time.

3차원으로 경사진 분사홀(131)은, 전술된 제1경사각(θ1)만을 구비한 2차원으로 경사진 분사홀(131)과 같이, 배관(101) 직경의 1 내지 2배 부근에서 분사된 제2유체가 수렴되도록 제1경사각(θ1) 및 제2경사각(θ2)이 형성될 수 있다. The three-dimensionally inclined spray hole 131, like the two-dimensionally inclined spray hole 131 having only the above-described first inclination angle θ1, is sprayed in the vicinity of 1 to 2 times the diameter of the pipe 101. A first inclination angle θ1 and a second inclination angle θ2 may be formed so that the second fluid converges.

전술된 바와 같이, 본 발명의 일실시예에 따른 유체 흡입 및 혼합장치(100)는 2차원 또는 3차원적으로 경사진 분사홀을 배관 내측면에 복수개를 배치함으로써 분사된 유체가 회전되며 높은 난류 강도를 가지며 혼합 효율을 극대화할 수 있게 된다. As described above, in the fluid suction and mixing apparatus 100 according to an embodiment of the present invention, by arranging a plurality of two-dimensionally or three-dimensionally inclined spray holes on the inner surface of the pipe, the sprayed fluid is rotated and high turbulence It has strength and can maximize mixing efficiency.

또한, 유체 흡입 및 혼합장치(100)에 분사홀(131)에서 분사된 유체가 배관(101) 직경의 1 내지 2배 사이에서 수렴되도록 경사 각도를 형성시킴으로써 균일하고 안정적인 혼합이 가능하도록 한다. In addition, by forming an inclination angle so that the fluid injected from the injection hole 131 in the fluid suction and mixing device 100 converges between 1 and 2 times the diameter of the pipe 101, uniform and stable mixing is possible.

이러한 본 발명의 유체 흡입 및 혼합장치(100)은 제2유체가 압축된 기체(예를 들면, 1.5 내지 4 bar의 가압 공기)일 경우, 분사홀(131)에서 고속으로 분사된 공기에 의해 배관 내에 강한 소용돌이(tornado)가 발생하게 되고, 그 결과 제1유체(또는 입자를 포함하는 제1유체)를 강력하게 흡입할 수 있는 진공(vacuum)을 생성하게 된다. In the fluid suction and mixing device 100 of the present invention, when the second fluid is a compressed gas (for example, 1.5 to 4 bar of pressurized air), a pipe is used by the air injected at high speed from the injection hole 131 . A strong tornado is generated within, and as a result, a vacuum capable of strongly sucking the first fluid (or the first fluid including particles) is generated.

즉, 본 발명의 유체 흡입 및 혼합장치(100)는 유체들을 혼합하는 이덕터(educt) 뿐만 아니라 이젝터(educt) 기능을 동시에 수행할 수 있는 장점이 있다.That is, the fluid suction and mixing device 100 of the present invention has the advantage of simultaneously performing an eductor function for mixing fluids as well as an ejector function.
