Description

벤튜리형 침전장치{VENTURI TYPE PRECIPITATION DEVICE}Venturi Type Precipitator {VENTURI TYPE PRECIPITATION DEVICE}

본 발명은 수질오염을 방지하기 위하여 각 오염발생원에서 배출되는 폐수를 보다 효율적으로 침전 정화 처리하도록 이루어진 침전장치에 관한 것으로, 특히 침전장치의 정류통 구조를 벤튜리 압력을 이용하도록 개선하여 침전속도를 빠르게 이루도록 한 벤튜리형 침전장치에 관한 것이다.The present invention relates to a sedimentation device configured to more effectively settle and purify wastewater discharged from each pollution source in order to prevent water pollution. In particular, the sedimentation speed of the sedimentation device can be improved by using venturi pressure. It relates to a venturi-type sedimentation device that achieves fast.

일반적으로 각종 산업폐수와 골재 세척폐수 및 생활하수 등의 정화를 위해서는 수처리 장치를 이용하게 되는데, 그 중 많이 이용되고 있는 것 중의 하나가 침전장치이다.In general, a water treatment device is used for purification of various industrial wastewater, aggregate washing wastewater, and domestic sewage, and one of the most widely used is a precipitation device.

침전이란 하수나 원수에 포함된 침전물의 침강속도를 증가시키는 것으로서 오래 전부터 이용되고 있는 수처리 중 가장 중요한 조작중의 하나로 물보다 무거운 입자는 정체된 물 또는 극히 흐름이 느린 물에서 침강하여 물과 분리되는 현상이다.Sedimentation is an increase in the sedimentation rate of sewage or raw water, which is one of the most important operations in water treatment that has been used for a long time. Particles heavier than water are separated from the water by sedimentation in stagnant or extremely slow water. It is a phenomenon.

이러한 원리를 이용하여 원수를 천천히 흐를 수 있는 넓은 지(池)에 유입시켜 입자(현탁물)를 분리하는 것이 침전지(沈澱池)이나, 이때 침전지의 크기가 매우 커지므로 침전지의 면적을 줄이고 침전속도를 빠르게 하는 기술이 필요한 데, 이것이 침전장치이다Using this principle, sedimentation basin is introduced into a large basin where raw water can flow slowly, but the sedimentation basin becomes large. At this time, the sedimentation basin becomes very large. Technology is needed to speed up

또, 물보다 무거운 입자는 정체된 물 또는 극히 흐름이 느린 물에서 침강하여 분리가 되므로, 먼저 플록 형성과정을 통해 침전물의 입경을 크게 하여 침강속도를 증대시키게 되는데, 여기서, 침강속도는 입자의 크기, 밀도, 형상물의 온도(점성) 등에 따라 결정되는 데, 스토크스의 식이 사용된다.In addition, particles heavier than water are separated by sedimentation in stagnant water or extremely slow water, so that the sedimentation rate is increased by increasing the particle size of the sediment through floc formation, where the sedimentation rate is the size of the particles. In order to determine the density, the temperature (viscosity) of the shape, and the like, Stokes' equation is used.

즉, In other words,

W : 입자의 침강속도(m/sec)W: Sedimentation rate of particles (m / sec)

ρs : 입자의 밀도(g/㎤)ρs: density of particles (g / cm 3)

ρ : 물의 밀도(g/㎤)ρ: density of water (g / cm 3)

μ : 물의 점성계수(g/㎝·sec)μ: Viscosity coefficient of water (g / cmsec)

d : 입자의 직경(㎝)d: diameter of particle (cm)

g : 중력가속도(㎝/sec2) = 980㎝/sec2 g: Gravitational acceleration (cm / sec 2 ) = 980cm / sec 2

상기 식으로부터 알 듯이 침강속도는 입자직경의 2승에 비례해서 커지기 때문에 입자가 클수록 침강속도는 급격히 커진다.As can be seen from the above equation, since the sedimentation rate increases in proportion to the square of the particle diameter, the larger the particles, the larger the sedimentation rate is.

이러한 침강속도는 침전지의 흐름이 이상적이며 난류나 편류가 없고, 조용하게 흘러가는 상태를 가정한 것이다.This settling velocity assumes that the settling stream is ideal, free from turbulence or drift, and flowing quietly.

그러나 대부분의 침전지에서는 유입관에서의 제트류, 흐름에 의한 난류, 유입수의 현탁물 농도에 의해 생기는 밀도류의 영향을 받아서 침전지 내의 흐림이 일정하지 않다.However, in most sedimentation basins, the cloudiness in the sedimentation basin is not constant due to the flow of jets in the inlet duct, turbulence caused by the flow, and the density flow caused by the concentration of the influent.

따라서, 침전장치는 집수조를 비롯한 응집조, 침전조 등을 별도의 장치로 각각 설치하거나, 또는 일체로 구비하고 있는 것이 있으나, 분리형 침전장치의 경우에는 대개 대용량이고 처리수질이 중요할 때 사용되며, 일체형 침전장치의 경우, 소용량이거나, 처리수질의 기준이 낮을 때 많이 이용되고 있다.Therefore, the sedimentation apparatus is provided with a segregation tank, a sedimentation tank, and a sedimentation tank, etc. as separate apparatuses, or may be provided as an integrated device. In the case of a precipitation apparatus, it is used a lot when it is a small capacity | capacitance or a low standard of treated water quality.

또, 개량형 침전장치도 있으나, 상기 개량형 침전장치의 경우는 중앙의 정류통에 유도막을 설치하여 유입수에 혼화, 응집의 효과를 얻고 있는 경우도 있다.In addition, although there is an improved precipitation apparatus, in the case of the improved precipitation apparatus, an induction membrane may be provided in the central rectification cylinder to obtain the effect of mixing and flocculation in the influent.

그 한 예로, 종래의 일체형 침전장치에서는 도 1에 도시된 바와 같이, 원수와 고분자 응집제를 동시에 중력방향으로 인입하여 유입수의 반응 및 응집작용이 일어나도록 하는 중공형 파이프 형상의 반응부(110)가 중앙부에 형성되고, 상기 반응부(110)를 수용하며, 반응 및 응집작용이 완료된 유입수를 하부에서 상부 방향으로 가이드 하여 반응부(110)의 외주연을 따라 상승된 후, 상부에서 출력되도록 하며, 유입수가 상부 방향으로 이동하는 도중에 경사판(120)을 통해 슬러지를 걸러내는 침전부(130)와, 상기 침전부(130)의 하부에 위치하며, 침전부(130)에서 걸러진 슬러지를 모으는 호퍼형 농축부(140)를 포함하여 형성된다.As an example, in the conventional integrated precipitation apparatus, as shown in FIG. 1, a hollow pipe-shaped reaction part 110 for introducing raw water and a polymer flocculant at the same time in the direction of gravity to cause reaction and agglomeration of influent water occurs. It is formed in the central portion, and accommodates the reaction unit 110, guides the inlet water is completed after the reaction and coagulation action from the bottom to the upper periphery of the reaction unit 110, and then outputted from the upper, A hopper-type concentrator, which is located at the bottom of the sedimentation unit 130 and the sedimentation unit 130 to filter sludge through the inclined plate 120 while the inflow water moves upward, collects the sludge filtered at the sedimentation unit 130. It is formed including the part 140.

그리고, 상기 반응부(110)는 원수와 고분자 응집제가 잘 섞일 수 있도록 원수와 고분자가 섞인 액체를 가이드 하는 슬라이딩 콘(111)과, 상기 액체의 유동을 조절하는 배플 플레이트(112)가 다수 개 설치되어 있다.The reaction unit 110 includes a sliding cone 111 for guiding a liquid mixed with raw water and a polymer so that raw water and a polymer flocculant are mixed well, and a plurality of baffle plates 112 for controlling the flow of the liquid. It is.

그러나, 상기와 같은 구성의 침전장치는 원수와 응집제를 중력방향 즉, 상부에서 인입시키도록 되어 있어, 토출용 펌프와 중력작용에 의해 하부로 이동하게 된다고 하나, 긴 파이프 형상의 반응부로 인해, 원수와 응집제의 혼합 및 침전부로의 용이한 순환이 힘든 문제점이 있고, 또 다수의 경사판(120) 설치로만 원수에 포함된 슬러지를 제거하도록 한 것은 정류효과가 떨어지는 문제점도 있다.However, the sedimentation device of the above-described configuration is intended to draw the raw water and the flocculant in the gravity direction, that is, the upper part, and to be moved downward by the discharge pump and the gravity action. However, due to the long pipe-shaped reaction part, the raw water There is a problem that the easy mixing and mixing of the flocculant and the settling section is difficult, and the sludge included in the raw water only by installing a plurality of inclination plates 120 has a problem in that the rectifying effect is lowered.

따라서, 본 발명은 상기와 같은 종래의 여러 문제점을 해결한 것으로서, 본 발명의 목적은 동일한 침전지 크기에서도 작은 부하율을 유지하도록 하기 위해, 벤튜리형 혼화, 응집 정류통과 주름경사판을 설치하여 침전시설을 단순화하고 침전효율을 높여 침전조에서 혼화 및 응집을 효과적으로 빠르게 이루도록 한 벤튜리형 침전장치를 제공함에 있는 것이다.Therefore, the present invention solves the various problems as described above, the object of the present invention is to simplify the sedimentation facility by installing a venturi-type mixing, cohesive rectifying tube and a pleated slant plate in order to maintain a small load rate even in the same sedimentation basin size And it is to provide a Venturi-type precipitation apparatus to increase the settling efficiency to quickly and effectively achieve the mixing and flocculation in the settling tank.

상기한 본 발명의 벤튜리형 침전장치를 첨부된 도면을 참조하여 좀 더 상세히 설명하면 다음과 같다.Referring to the venturi type precipitation apparatus of the present invention described above in more detail with reference to the accompanying drawings.

먼저, 도 2 는 본 발명의 벤투리형 침전장치를 일부 절개하여 나타낸 사시도이고, 도 3 은 도 2의 단면도이며, 도 4 는 본 발명의 벤투리형 정류통의 확대 상세도로서 도시된 바와 같이, 호퍼형의 침전조(10) 상부 내 벽면으로는 다수의 정류수배출기(11)의 일측단부가 내주를 따라 부착 형성되고, 대향하는 타 일측단부는 중앙부에 형성된 원통형의 격벽(12) 외주면을 따라 부착 형성된다.First, Figure 2 is a perspective view showing a part of the venturi type precipitation apparatus of the present invention, Figure 3 is a cross-sectional view of Figure 2, Figure 4 is an enlarged detail of the venturi type rectifier of the present invention as shown One end of the plurality of rectifier water dischargers 11 is formed along the inner circumference of the hopper-type sedimentation tank 10 and the inner circumferential surface of the hopper-type sedimentation tank 10 is formed along the outer circumferential surface of the cylindrical partition 12 formed at the center. Attachment is formed.

상기 정류수배출기(11)는 사방(四方)을 막은 후, 측면으로만 다수의 유입공(11a)을 형성하고 일측 방향으로는 정류수 배출관(16)을 수용하도록 형성된다.The rectified water discharger 11 is formed to block the four sides (four way), to form a plurality of inlet holes (11a) only on the side and to receive the rectified water discharge pipe 16 in one direction.

그리고, 상기 다수의 정류수배출기(11) 하부로는, 역시 침전조(10)의 내벽면과 원통형 격벽(12) 외주면 사이에 주름경사판(13)이 형성된다.In addition, under the plurality of rectified water dischargers 11, a pleated inclined plate 13 is formed between the inner wall surface of the settling tank 10 and the outer peripheral surface of the cylindrical partition 12.

상기 주름경사판(13)은 최소한의 공간에서도 분리 표면적을 극대화하도록 물결형상 또는 골판지 골형상 등의 주름을 형성하고, 개략 V형의 경사를 이루도록 함으로써, 물이 주름을 따라 굴곡되어 흐르도록 하였다.The corrugated slope plate 13 forms corrugations such as wavy or corrugated bone shapes to maximize separation surface area even in a minimum space, and forms an inclined V-shape to allow water to flow along the corrugations.

또, 상기 주름경사판(13) 하부로는 저류벽(14)이 경사지도록 형성된다.In addition, the storage wall 14 is formed to be inclined under the wrinkled slope plate 13.

상기 저류벽(14)은 원수가 주름경사판으로 올라가기 전에 1차적으로 현탁물(슬러지)을 걸러 침전조 하부로 유도하게 된다.The reservoir wall 14 first filters the suspension (sludge) before the raw water rises to the corrugated slope plate to guide the lower portion of the settling tank.

또, 상기 원통형 격벽(12) 중앙부에는, 그 하부로는 응집보조제 투입관(19)과 내벽에 돌출형의 나선형 회전유도부(22)를 갖는 혼합부(21)와, 상부로는 다수의 통공(24a)을 갖는 복수의 정류판(24)과, 유도공(25a)을 갖는 유도판(25) 및 응집제투입관(18)을 갖는 정류부(23)로 이루어지는 정류통(20)이 형성된다.Further, in the central portion of the cylindrical partition 12, a mixing portion 21 having a coagulation aid input pipe 19 at the lower portion and a spiral rotating guide portion 22 protruding at the inner wall thereof, and a plurality of through holes at the upper portion thereof. The rectification cylinder 20 which consists of the several rectifying plate 24 which has 24a, the guide plate 25 which has the guide hole 25a, and the rectifying part 23 which has the coagulant injection tube 18 is formed.

상기 정류통(20)은 벤튜리형 관으로 형성하였다.The rectifier 20 was formed of a venturi tube.

즉, 벤투리 효과의 정리를 응용하여 하단부를 유선형의 대경부로 구성하고,상단부를 소경부로 구성하므로써, 압력차가 일어나도록 만들었다.In other words, by applying the theorem of the Venturi effect, the lower end portion is composed of a streamlined large diameter portion, and the upper end portion is formed of a small diameter portion, thereby causing a pressure difference.

상기와 같은 벤튜리형 관은, 대구경과 소구경에 의해 유입과 배출에 따른 압력차로 강력한 상승작용이 일어나 유체를 상승시키기 위한 별도의 장치 없이도, 물을 상승시키게 된다.Venturi-type tube as described above, the strong synergism occurs due to the pressure difference according to the inflow and discharge by the large diameter and the small diameter to raise the water, without a separate device for raising the fluid.

또한, 상기 정류통(20)은 상부에 형성된 정류부(23)를 하부에 형성된 혼합부(21)와는 반대의 형태 즉, 하단을 소구경으로 하고, 상단을 대구경으로 형성하여 원수의 흐름을 점차로 느리게 흐르도록 하였으며, 내부로는 다수의 배출공(24a)을 갖는 정류판(24)과 원수의 흐름을 유도하도록 한 유도공(25a)을 갖는 유도판(25)을 격순으로 설치하여 응집효과는 물론 물의 정류흐름과 순환작용을 이루도록 하였다.In addition, the rectifier 20 has a shape opposite to the mixing part 21 formed at the upper part of the rectifying part 23 formed at the upper part, that is, the lower part having a small diameter, and the upper part having a large diameter. In order to flow, the rectifying plate 24 having a plurality of discharge holes (24a) and the guide plate (25) having a guide hole (25a) for inducing the flow of raw water are installed in order and the coagulation effect of water Rectification flow and circulation were achieved.

한편, 도 5 는 본 발명에 의한 혼합부(21)의 나선형 회전유도부를 다른 실시 예로 나타낸 것으로서, 나선형 회전유도부를 돌출형이 아닌 홈형의 회전유도부(22a)로 형성한 것이다.On the other hand, Figure 5 shows a helical rotation guide portion of the mixing portion 21 according to the present invention as another embodiment, the helical rotation guide portion is formed of a groove-shaped rotation guide portion 22a rather than a protrusion.

상기와 같은 홈형의 회전유도부(22a) 역시 유입되는 원수의 회전을 용이하게 이루도록 함으로서, 응집보조제와 원수의 혼합작용을 이루는 데 동일한 작용을 하게 된다.Rotation guide portion 22a of the groove-type as described above also facilitates the rotation of the incoming raw water, and performs the same action to achieve the mixing action of the coagulant aid and the raw water.

이와 같은 구성으로 이루어진 본 발명의 벤튜리형 침전장치의 동작관계를 살펴보면 다음과 같다.Looking at the operation relationship of the venturi type precipitation apparatus of the present invention made of such a configuration as follows.

먼저, 침전장치(100)의 하부를 통해 정류통(20)의 하부에 형성된 혼합부(21)와 연결된 원수 유입관(15)으로부터 유입되는 원수는 혼합부(21)의 측면에 형성된응집보조제 투입관(19)을 통해 투입되는 응집보조제(가성소다)와 급격히 혼화된다. 이와 같은 혼화의 용이함은, 상기 혼합부(21) 내에 형성된 나선형 회전유도부(22)에 의해 이루어진다.First, the raw water flowing from the raw water inlet pipe 15 connected to the mixing unit 21 formed at the bottom of the rectifier 20 through the lower part of the precipitation apparatus 100 is introduced into the coagulation aid formed on the side of the mixing unit 21. It is rapidly mixed with the coagulant aid (caustic soda) introduced through the tube (19). Such easy mixing is achieved by the helical rotation guide 22 formed in the mixing section 21.

또한, 상기 혼합부(21)는 하단이 대구경이고, 상단이 소구경으로 벤튜리형 관으로 형성되어 있어, 벤튜리 효과에 의한 압력차의 발생으로 더욱 더 효과적인 혼화작용과 상승작용을 일으키게 된다.In addition, the mixing portion 21 has a large diameter at the lower end and a small diameter at the upper end is formed as a venturi-type tube, thereby causing a more effective mixing and synergy by the generation of pressure difference due to the Venturi effect.

상기 혼합부(21)를 통과한 응집보조제와 혼화된 원수는 상부 정류부(23)에 유입되면서 다시 응집제투입관(18)을 통해 투입되는 응집제와 혼화되면서 유도판(25) 일측에 형성된 유도공(25a)을 통해 상승 유도되어 격순으로 설치된 다수의 배출공(24a)을 갖는 정류판(24)을 격순으로 거치게 되며, 응집효과를 높이게 된다.Raw water mixed with the coagulant adjuvant passing through the mixing unit 21 is introduced into the upper rectifying unit 23 and mixed with the coagulant introduced through the coagulant input pipe 18 and formed on one side of the guide plate 25. Increasing through) through the rectifying plate 24 having a plurality of discharge holes (24a) installed in a sequential order in order to increase the cohesive effect.

상기 정류통(20)에서 혼화작용과 정류흐름에 의해 응집된 원수는 원통형의 격벽(12) 내를 통과하여 상기 원통형 격벽(12)외부로 배출되면서, 침전조(10) 하부에 경사지게 형성된 저류벽(14)에 의해 1차 적으로 현탁물(슬러지)을 제거시켜 침전조 하부로 유도하게 된다.The raw water aggregated by the mixing and rectifying flow in the rectifier 20 passes through the cylindrical partition 12 and is discharged to the outside of the cylindrical partition 12, and is formed inclined to the bottom of the settling tank 10. 14) the suspension (sludge) is first removed to guide the bottom of the sedimentation tank.

즉, 상기 각 과정을 거치면서 응집된 원수는 흐름을 타고 다시 상승을 이루게 되는데 이때 저류벽(14) 부딪히면서 응집된 무거운 현탁물은 낙하하게 되고 일부 미세한 현탁물과 정류된 원수만 상승하게 된다.That is, the aggregated raw water through the above process is rise again through the flow at this time, the heavy suspension aggregated while hitting the storage wall (14) falls and only some fine suspension and rectified raw water rises.

상기 저류벽(14)을 통과하여 상승되는 일부 미세한 현탁물을 포함한 원수는 침전조(10) 내벽과 원통형격벽(12) 사이에 형성된 주름경사판(13)을 통과하면서 미세한 현탁물까지 제거된다.Raw water including some fine suspensions which rise through the storage wall 14 is removed to the fine suspension while passing through the pleat inclined plate 13 formed between the inner wall of the settling tank 10 and the cylindrical partition 12.

여기서, 상승된 원수는 물결 모양 또는 골판지의 골형상 등으로 V형으로 경사지게 형성된 주름경사판(13)의 굴곡을 따라 천천히 통과하여 흐르게 되므로, 2차 적으로 현탁물을 완전히 제거하게 되고, 이렇게 제거된 침전물은 침전조(10) 하부측에 형성된 침전물 배출관(17)을 통해 배출되게 된다.Here, the elevated raw water is slowly passed along the curvature of the corrugated sloping plate 13 formed to be inclined in the V-shape in the shape of a corrugated or corrugated cardboard, so as to completely remove the suspended matter secondarily, thus removed The precipitate is discharged through the sediment discharge pipe 17 formed on the lower side of the sedimentation tank 10.

그리고, 상기 주름경사판(13)을 통과한 정류된 물은 상기 주름경사판(13) 상부에 형성된 정류수배출기(11)의 측면에 형성된 유입공(11a)을 통해 유입되어, 정류수 배출기(11)의 일측단으로 형성된 정류수배출관(16)을 통해 최종 배출되도록 이루어진다.And, the rectified water passing through the wrinkled slope plate 13 is introduced through the inlet hole (11a) formed on the side of the rectified water discharger 11 formed on the wrinkled slope plate 13, the rectified water discharger (11) Final discharge is made through the rectified water discharge pipe 16 formed in one side of the.

이상에서 상세히 설명한 바와 같이, 본 발명에 의한 벤튜리형 침전장치는 벤튜리형 관으로 형성한 정류통과 상기 정류통의 하부 혼합부에 형성된 나선형 회전유도부와 상부에 격순으로 형성된 유도판 및 정류판과 주름경사판 등에 의해 침강속도증대와 혼화 및 응집효과를 높임으로서, 침전지의 크기를 줄일 수 있는 등의 효과가 있는 것이다.As described in detail above, the venturi-type precipitation apparatus according to the present invention is a helical rotary guide portion formed in a rectifying tube formed of a venturi-type tube and a lower mixing portion of the rectifying tube, and an induction plate, a rectifying plate, and a pleated inclined plate formed in an upper order.
