The present invention relates to a nozzle injection type chemical dilution system capable of improving the coagulation efficiency by the chemical dilution.

현재, 모든 정수장에서 사용되고 있는 다이아프램식 약품펌프에 의한 투입과 혼화기의 가동에 의한 급속혼화방식등을 채용하고 있는 바, 상기 정수장의 수처리공정을 보면 약품(응집제)의 투입 → 급속혼화 → 응집 → 침전 → 여과 → 소독 → 가압송수등을 통해 시, 도 정수장등의 과정을 거치게 된다.At present, the diaphragm type chemical pump used in all water purification plants and the rapid mixing method by operating the mixer are adopted. The water treatment process of the water purification plant shows the addition of chemicals (coagulant) → rapid mixing → flocculation. → Sedimentation → Filtration → Disinfection → Pressurized water and so on.

제 1 도는 종래의 약품희석시스템을 도시해 놓은 것으로, 정수장으로 유입되는 원수는 착수정(1)을 거쳐 혼화지유입지(22)로 공급되고, 응집제의 약품은 약품탱크(15)에서 적은 량으로 보조탱크(6)를 통해 다이아프램식 약품펌프(7)로서 펌핑되어 희석수탱크(8)에 공급되는 한편 희석수를 혼합하여 일정한 량을 상기 혼화지유입지(22)로 중력낙하투입하게 된다.Figure 1 shows a conventional chemical dilution system, raw water flowing into the water purification plant is supplied to the mixing site inlet 22 through the landing well (1), the chemical of the flocculant is assisted in a small amount in the chemical tank (15) It is pumped as a diaphragm type chemical pump 7 through the tank 6 and supplied to the dilution water tank 8, while diluting water is mixed so that a certain amount of gravity is introduced into the mixed paper land input 22.

여기서 도면부호 h1는 착수정(1)의 수두높이, 도면 h2는 혼화지유입지(h2)의 수두높이를 나타낸다.Wherein the numeral 1 is the head height h, h 2 of the drawings chaksujeong (1) represents the height of the mixing head Jiyugaoka position (h 2).

상기 약품펌프(7)의 구동은 중앙조정실 컴퓨터(10)에 의해 콘트롤러(9)가 작동되어 속도제어에 의한 약품투입량을 조절하게 된다.The driving of the chemical pump 7 is to operate the controller 9 by the central control room computer 10 to adjust the chemical input amount by the speed control.

상기 원수의 탁도는 계절에 따라 장마절 및 우기에 수시로 변화를 갖는데, 탁도별로 조절된 응집약품량이 혼화지유입지(22)에 투입된 다음 이를 통하여 혼화지(3)에 유입된다. 여기서 혼화지(3)의 혼화기(4)가동에 의한 약품과 원수와의 혼합으로 응집이 용이한 상태의 원수로 변화하게 된다.The turbidity of the raw water has a change in the rainy season and rainy season often according to the season, the amount of coagulant controlled by turbidity is introduced into the mixed paper land inlet 22 and then introduced into the mixed paper (3). Here, the mixture of the chemicals and the raw water by the operation of the blender 4 of the mixed paper 3 is changed to the raw water in an easily aggregated state.

상기 약품탱크(15)로부티의 응집약품은 보조탱크(6)를 거쳐 콘트롤러(9)에 의해 제어된 약품펌프의 회전속도에 따라 약품의 양이 희석수탱크(8)로 투입되고, 이 희석탱크(8)내에서 희석수와 혼합된 후 각지별로 균일하게 분산되어 투입하게 된다.The coagulant drug of the drug tank (15) is injected into the dilution water tank (8) according to the rotational speed of the chemical pump controlled by the controller (9) via the auxiliary tank (6), this dilution After mixing with the dilution water in the tank (8) is uniformly dispersed in each place is put.

상기 탱크내에서의 응집약품과 희석수는 약 10분간의 혼합체류시간을 가진 다음 혼화지유입지(22)의 상부 4개 지점에 중력낙하투입하고 있으나, 약품의 희석수탱크(8)내에서의 과대한 체류시간으로 약품의 응집효율이 저하되고 있다.In the tank, the flocculant and the dilution water are introduced into the upper four points of the mixed paper land site 22 with a mixing residence time of about 10 minutes, but the chemicals in the dilution water tank 8 Excessive residence time reduces the cohesion efficiency of the drug.

또, 상기 혼화지유입지(22)에서의 약품투입지점은, 혼화지유입지(22)의 위어상부에서 약품을 중력낙하투입하며 혼화지유입지(22)에서 약 17초간 체류한 다음 전부 열려져 있는 전동밸브(V)를 통해 혼화지(3)에 가서 비로서 설치된 혼화기(4)에 의해 약 40초 동안 급속혼화되고 있어, 착수정(1)의 유출위어낙차(약 30cm)및 혼화지유입지(22)의 위어낙차(약 50cm)를 혼화에 활용하지 못하고 있고 약 17초간 혼화공정이 지연되고 있어 약품의 원수와의 반응효율도 저하되고 있다.In addition, the chemical injection point at the mixing point 22 is gravity-dropping the chemical at the upper weir of the mixing point 22, and stays at the mixing point 22 for about 17 seconds, and then is fully open. It is rapidly mixed for about 40 seconds by the mixer (4) installed as a rain through the (V) mixing paper (3), and the outflow weir drop (about 30 cm) of the landing well (1) and the mixing paper holding site (22). Weir drop (about 50cm) is not used for mixing, and the mixing process is delayed for about 17 seconds, and the reaction efficiency with the raw water of the chemical is also reduced.

또한, 혼화지(3)의 체류시간 40초에서의 설계속도구배 예컨대 700sec-1를 내기 위해 혼화기(4)의 소요동력이 커서(75HP), 임페라, 축, 베어링, 리테이너등에 무리를 줌으로 소음, 진동, 고장빈도가 높은 상태로 있게 되었다.In addition, the power required of the blender 4 is large to produce a design speed gradient, for example, 700 sec -1 at the residence time of the blended paper 3, such as 700 sec -1 . The noise, vibration, and failure frequency remained high.

본 발명은 상기와 같은 결점등을 해소하기 위해 발명한 것으로, 종래의 다이아프램식 약품펌프에 의한 투입과 혼합기의 가동에 의한 급속혼화방식을 개선하여 상기 다이아프램식 약품펌프와 혼화지의 혼화기를 설치하지 않고 노즐분사펌프와 다수의 노즐분사를 통하여 종래보다 정확한 약품투입과 금속혼화가 가능하도록 되어 있어 약품투입량의 조절과 약품응집효율을 향상시킬 수 있는 노즐분사식 약품희석시스템을 제공하고자함에 그 목적이 있다.The present invention has been invented to solve the above-mentioned defects, improve the rapid mixing method by the input of the conventional diaphragm-type chemical pump and the operation of the mixer to install the diaphragm-type chemical pump and blender It is possible to provide a chemical injection and chemical dilution system that can adjust the chemical injection volume and improve the chemical coagulation efficiency through the nozzle injection pump and the multiple nozzle injection. have.

상기 목적dmf 달성하기 위한 본 발명의 노즐분사식 약품희석시스템은, 착수정(11)에서 월류벽을 0.5m 중고하고 혼화지유입지(22)에서 4개소의 밸브(14)를 약 50% 정도 닫은 상태로 유지하도록 설치되고, 자동콘트롤밸브(19)와 약품유량계(18)를 통한 약품공급라인과 희석수탱크(17)로부터의 희석수공급라인을 연결한 다음 노즐분사펌프(12)에 설치되며, 상기 노즐분사펌프(12)가 분사하는 약품과 희석수의 혼합수는 혼화지(13)의 유입구에서 분사유입되도록 4개의 분사노즐(16,16',16",16"')이 설치된 것을 특징으로 한다.In the nozzle injection type chemical dilution system of the present invention for achieving the above object, the overflow wall is used at 0.5m in the landing well 11 and the valve 14 at the mixing site 22 is about 50% closed. It is installed to maintain, and connected to the chemical supply line through the automatic control valve 19 and the chemical flow meter 18 and the dilution water supply line from the dilution water tank 17, and then installed in the nozzle spray pump 12, Four injection nozzles (16, 16 ', 16 ", 16"') are installed so that the mixed water of chemicals and dilution water injected by the nozzle injection pump (12) is injected at the inlet of the mixed paper (13). do.

이하 본 발명의 실시예를 예시도면에 의거하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제 2 도는 본 발명의 실시예에 관한 약품희석시스템을 도시해 놓은 것으로, 본 발명의 노즐분사식 약품희석시스템은 정수장의 수처리공정중 응집제투입 및 금속혼화공정을 개선하여 노즐분사펌프(12)가 분사하는 희석수와 혼합된 응집제 약품이 혼화지(13)의 유입구에서 원수속에 분사유입되면 혼탁한 원수와 정면으로 분사마찰을 일으키며 응집제약품과 혼탁한 원수가 급속혼화를 일으켜서 응집이 용이한 상태의 물로 변화시키도록 되어 있다.Figure 2 shows a chemical dilution system according to an embodiment of the present invention, the nozzle injection type chemical dilution system of the present invention improves the coagulant injection and metal mixing process during the water treatment process of the water purification plant to spray the nozzle injection pump 12 When the coagulant drug mixed with dilution water is injected into the raw water at the inlet of the mixing paper 13, the spraying friction occurs in front of the turbid raw water and the raw water turbidity with the coagulant drug causes the rapid mixing and thus the water is easily coagulated. It is supposed to change.

즉, 정수장의 착수정(11)으로 유입되는 원수는 계절에 따라 장마철 및 우기에 탁도가 수시로 변화하게 되는 바, 일례로 탁도(ppm)가 높을때 원수자체가 매우 혼탁하고 흐린 흙탕물상태로 되어 후술하게 될 노즐분사펌프(12)가 응집제약품과 희석수와의 혼합수를 혼화지(13)의 유입구에서 분사투입하여 급속혼화효과를 발생시켜 혼화지(13)에서 원수의 혼탁하고 흐르게 된 작은 알갱이 및 불순물들을 응결이 용이한 형상으로 변화시킨다음 응집지에서의 응집과정과 침전지에서의 침전과정을 거치게 되면, 원수속에 함유된 탁질등이 대부분 제거된 투명상태의 물이 되어 여과지내의 여과공정으로 보내게 된다.In other words, the raw water flowing into the water purification plant 11 of the water purification plant changes from season to season during the rainy season and rainy season. For example, when the turbidity (ppm) is high, the raw water itself becomes very turbid and cloudy muddy water. The nozzle spray pump 12 is injected into the mixed water of the flocculant and the dilution water at the inlet of the mixed paper 13 to generate a rapid mixing effect, so that the small particles of turbidity and flow of the raw water in the mixed paper 13 and After the impurities are changed into a congealable form, the coagulation process in the flocculation paper and the precipitation process in the flocculation paper are carried out, and the turbidity contained in the raw water is mostly removed to be sent to the filtration process in the filter paper. do.

상기 착수정(11)을 통과하는 원수의 탁도에 따라 조절투입되는 약품의 양은 사실상 매우 적은 량으로 원수전체에 분사하기는 어려움으로 분사량을 늘리기 위해 희석수탱크(17)에서의 희석수와 약품을 노출분사펌프(12)가 동시 흡입, 펌프회전에 의하여 균등혼합한 다음 가압송수하여 섞어 혼화지(13)의 유입구에 실치된 분사노즐(16,16',16",16"')의 형태(제 3 도 참조)로 분사유입시키면 상기 혼화지(13)에서 유입수의 원수와 정면으로 분사마찰을 일으켜 종래의 혼화지가 설치되지 않고서도 급속혼화를 하게 되어 최대응집효과를 갖게 된다.The amount of chemicals adjusted and controlled according to the turbidity of the raw water passing through the landing well 11 is actually very small and difficult to spray the whole raw water, so that dilution water and chemicals in the dilution water tank 17 are exposed to increase the injection amount. Type of injection nozzles 16, 16 ', 16 ", 16"' mounted at the inlet of the mixed paper 13 by mixing the injection pump 12 evenly by simultaneous suction and pump rotation, and then mixing them by pressurized water. Injecting the spray into the mixing paper 13 causes spray friction in front of the raw water of the inflow water in the mixed paper 13, which causes rapid mixing without the conventional mixed paper, thereby achieving the maximum aggregation effect.

또한, 제 4 도에 도시된 바와 같이 종래의 혼화기 가동과 달리 노즐분사(16)에 의한 급속혼화에 의해 혼화지(13)의 흡입구에서 혼화지유입지(22)의 50% 열린 전동밸브(14)를 통과한 유입수와 응집제의 접촉시간이 최소화됨으로 응집효율이 향상된다.In addition, as shown in FIG. 4, unlike the conventional mixer operation, the electric valve 14 opened 50% of the mixed paper inlet 22 at the inlet of the mixed paper 13 by rapid mixing by the nozzle injection 16. Cohesion efficiency is improved by minimizing the contact time between the influent and coagulant passing through).

상기 원수의 공급량과 응집제의 투입은 일정한 관계를 맺고 있는데, 이는 이미 시험실에서 수시로 원수를 채취하여 탁도시험을 한 결과에 따라 약품투입을 하며, 종래의 다이아프램식 약품펌프대신에 사용하는 고압분사용 노즐분사펌프(12)에서의 약품과 희석수의 혼합은 혼합비율과는 아무런 상관관계가 없으며 단지 노즐분사가 가능하도록 하여 일정한 양을 확보하기 위하여 설치되어 있다.The supply amount of raw water and the input of flocculant have a certain relationship, which is already input from the laboratory from time to time to collect the raw water and the chemical input according to the results of turbidity test, using a high-pressure injection instead of the conventional diaphragm type chemical pump The mixing of chemicals and dilution water in the nozzle injection pump 12 has no correlation with the mixing ratio, and is provided only to ensure a constant amount by enabling nozzle injection.

한편, 약품탱크(15)로부터의 응집제는 자연수두를 이용한 약품공급으로써 중앙조정실 컴퓨터(21)에 의해 콘트롤러(20)가 작동됨에 따라 자동콘트롤밸브(19)와 약품유량계(18)에 의한 제어 및 통제하에 통과하게 되는데, PAC(폴리염화알루미늄)은 약품을 상기 약품유량계(18)와 자동콘트롤밸브(19)를 통해 원수의 탁도변화에 대해 약품의 투입량을 정량조절함으로 정확하게 결정하여 종래의 대략적인 약품투입과 비교할때 정확성을 기할 수 있고 고가의 약품을 절약할 수 있다.Meanwhile, the coagulant from the chemical tank 15 is controlled by the automatic control valve 19 and the chemical flow meter 18 as the controller 20 is operated by the central control room computer 21 as a chemical supply using natural head. Under the control, PAC (polyaluminum chloride) is determined by precisely controlling the amount of chemical input to the turbidity change of raw water through the chemical flow meter (18) and the automatic control valve (19). Compared with the injection of drugs, the accuracy can be improved and expensive drugs can be saved.

상기 약품은 고압분사용 노즐분사펌프(12)로 공급되고 있지만 약품의 량이 매우 적으므로 희석수가 희석탱크(17)를 통해 공급되고 있음으로, 상기 노즐분사펌프(12)가 예컨대 5,8kg/㎠G의 압력으로 약품과 희석수를 흡입하면서 혼화지(13)의 유입구(예컨대 1100m/m)에 설치된 예컨대 4개의 분사노즐(16,16',16",16"' ; 제 3 도 참조)에 압력을 가하면 1mm의 작은 노즐구멍을 통해 18m/s의 속도로 분사하면서 유입된다.The chemical is supplied to the high pressure jet nozzle pump 12, but since the amount of chemical is very small, the dilution water is supplied through the dilution tank 17, so that the nozzle jet pump 12 is, for example, 5,8 kg / cm 2. Four injection nozzles 16, 16 ', 16 ", 16"' installed at the inlet of the mixed paper 13 (e.g., 1100 m / m) while suctioning chemicals and dilution water at a pressure of G; When pressure is applied, it flows in at a speed of 18 m / s through a small nozzle hole of 1 mm.

제 4 도에 도시된 방사형 분사노즐(16)의 노즐구멍갯수는 72개인데, 약품투입지점을 혼화지(13) 유입구의 4개 전동밸브(14) 배관 후단에 설치됨으로 4×72=288개로 되어 있다.The number of nozzle holes of the radial injection nozzle 16 shown in FIG. 4 is 72, and the chemical injection point is installed at the rear end of the four electric valves 14 at the inlet of the mixed paper 13 so that 4 × 72 = 288. It is.

즉, 제 3 도에 도시된 분사노즐(16,16',16",16"')의 형태는 1100m/m의 원주형태에 직선 및 45°각도로 1개의 분사노즐에 72개의 1m/m 구멍을 뚫어져 있고, 혼합지(13)의 유입구가 4개소임으로 분사노즐형태는 파이프 배관을 통해 4개의 노즐로 분배시키도록 되어 있다.That is, the shapes of the spray nozzles 16, 16 ', 16 ", 16"' shown in FIG. 3 are 72 1m / m holes in one spray nozzle at a straight line and 45 degree angle in the circumferential form of 1100m / m. And the injection nozzle type is distributed to the four nozzles through the pipe piping because the inlet of the mixing paper 13 is four places.

따라서, 본 발명에 있어서 희석 체류시간을 최소화하기 위해 노즐분사펌프(12)는 흡입측에 희석수라인과 약품라인을 동시에 연결하여 동시에 흡입한 다음 내부의 펌프임페라회전에 의해 최단시간내에 혼합하여 압송함으로, 투입지점의 노즐(제 3 도 참조)에서의 고압분사투입으로 약품과 콜로이드탁질과의 접촉면적을 최대화시켜 급속혼화효과와 응집효율을 극대화시킬 수 있다.Therefore, in the present invention, in order to minimize the dilution residence time, the nozzle injection pump 12 simultaneously connects the dilution water line and the chemical line to the suction side and inhales them, and then mixes and pumps them within the shortest time by the internal pump impeller rotation. Thus, by high-pressure injection injection at the nozzle of the injection point (see FIG. 3), the contact area between the chemical and the colloidal suspension can be maximized to maximize the rapid mixing effect and the flocculation efficiency.

또 종래의 착수정위어낙차와 혼화지위어낙차를 동시에 혼화지(13)의 유입구 배관내에서의 와류에 의한 혼화에너지로 활용할 수 있도록, 혼화지(13)의 유입구 배관밸브(14)를 50% 체절시켜 혼화지유입지(22)의 수위와 혼화지(13) 수위와의 수위차를 0.8m로 발생시키게 된다.In addition, the inlet pipe valve 14 of the mixed paper 13 is cut by 50% so that the conventional landing water drop and the mixed ground drop can be utilized as mixed energy due to vortices in the inlet pipe of the mixed paper 13 at the same time. The water level difference between the level of the mixed paper inflow site 22 and the level of the mixed paper 13 is generated at 0.8 m.

제 4 도에 도시된 바와 같이 상기 혼화지(13)의 배관내 와류에다 유입수의 반대방향으로 노즐분사펌프(12)에 의해 고압분사함으로 혼화지(13)에서 약품과 콜로이드탁질과의 접촉반응시간을 최소화시키고 충분한 혼합강도를 얻어내어 종래와 같이 혼화기를 사용하지 않아도 된다.As shown in FIG. 4, the reaction time between the chemical and the colloidal turbidity in the mixed paper 13 by high pressure spraying by the nozzle spray pump 12 in the opposite direction of the inflow water to the vortex in the pipe of the mixed paper 13 Minimization and sufficient mixing strength are achieved so that there is no need to use a mixer as in the prior art.

따라서, 본 발명은 종래와 같이 혼화기와 약품펌프를 설치하지 않음으로 정수장 초기건설시 상기 혼화기와 여러 제반 설비의 시공비용등을 절감할 수도 있다.Therefore, the present invention can reduce the construction cost of the mixer and various facilities during the initial construction of the water purification plant by not installing a mixer and chemical pump as in the prior art.

또 본 발명은 노즐분사와 약품투입의 자동콘트롤밸브 및 유량계를 통해 종래의 유지보수 및 개체비용절감유량계를 통한 정확한 약품투입을 통해 운영효율을 극대화시킬 수 있다.In another aspect, the present invention can maximize the operating efficiency through the precise injection of the drug through the conventional maintenance and individual cost-saving flowmeter through the automatic injection valve and flow meter of the nozzle injection and chemical injection.

이상 설명한 바와 같이 본 발명에 의하면, 종래의 다이아프램식 약품펌프에 의한 투입과 혼합기의 가동에 의한 급속혼화방식을 개선하여 상기 다이아프램식 약품펌프와 혼화지의 혼화기를 설치하지 않고 노즐분사펌프와 다수의 노즐분사를 통하여 종래보다 정확한 약품투입과 금속혼화가 가능하도록 되어 있어 약품투입량의 조절과 약품응집효율을 향상시킬 수 있는 노즐분사식 약품희석시스템을 제공할 수 있다.As described above, according to the present invention, it is possible to improve the rapid mixing method by the introduction of the conventional diaphragm type chemical pump and the operation of the mixer, and to provide a nozzle spray pump and a large number of nozzle spray pumps without installing the mixer of the diaphragm type chemical pump and mixed paper. It is possible to provide more precise chemical injection and metal admixture through the nozzle injection of the conventional nozzle injection type chemical dilution system that can control the chemical injection amount and improve the chemical coagulation efficiency.
