본 발명은 여과사내장형스크린을 구비한 용수여과장치에 관한 것으로서, 여과사들의 사이들 용수가 통과하는 동안에 여과사에 의해 이물질이 여과되도록 하는 용수여과장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water filtration device having a built-in screen for filtration yarns, and more particularly, to a water filtration device for filtering foreign substances by filtration yarns while water flows between filtration yarns.
댐과 같은 수원에서 최초로 공급되는 용수는 수차례의 여과과정을 거쳐 산업용수 또는 식수로 사용되게 된다. The first water supplied from a source such as a dam is filtered and used for industrial or drinking water.
이 때 각각의 여과과정마다 여과되는 이물질의 크기를 단계적으로 감소시킴으로써 이후 여과과정을 수행하는 여과장치에 과도한 부담을 주는 것을 피할 수 있다.At this time, by reducing the size of the foreign matter filtered in each step of filtration step can be avoided to put an excessive burden on the filtration device to perform the subsequent filtration step.
예를 들면 댐에서 공급되는 용수는 1차 용수여과장치에서 약 30마이크로미터 이상의 이물질들을 걸러내며, 2차로 여과사(모래) 또는 섬유여과를 통해 중간영역을 여과하여 더욱 정밀한 여과는 RO(Reverse osmosis, 역삼투), MF(Microfiltration, 정밀여과), UF(ultrafiltration, 한외여과) 등의 방식을 통해 0.1마이크로미터 이상의 물질을 걸러주게 된다.For example, the water supplied from the dam filters out more than about 30 micrometers of foreign matter from the primary water filtration system. Secondly, the intermediate area is filtered through filtration sand (sand) or fiber filtration. , Reverse osmosis), MF (Microfiltration, microfiltration), UF (ultrafiltration, ultrafiltration), and other methods to filter out more than 0.1 micrometer.
여과사를 이용한 여과장치는 일정기간 사용하면 여과사들의 사이에 일정수준 이상으로 이물질들이 끼워져 머무르게 되므로 여과사를 세척하여 끼워진 이물질들을 제거하는 과정이 필요하다. 종래의 여과사를 이용한 여과장치는 이물질들을 제거하는 동안에는 용수의 여과를 중단해야 했으므로, 여과장치 이후의 공정과 단락이되어 이를 방지하기위한 보조장치(예를 들면, 중간 집수조, 이송펌프)가 필요하며 전체적인 여과시간이 증가하는 단점이 있다. Filtration device using the filter sand is a certain period of time that foreign matters are sandwiched between the filter yarns to stay more than a certain level, it is necessary to remove the foreign matters by washing the filter yarns. Since the filtration device using a conventional filter sand had to stop filtration of water while removing foreign substances, an auxiliary device (for example, an intermediate collection tank and a transfer pump) is required to prevent the short circuit with the process after the filtration device. And there is a disadvantage that the overall filtration time increases.

도 6에 도시된 바와 같이, 본 발명에 따른 용수여과장치는 용수여과탱크(1)의 외부에서 공기공급수단(42)에 의해 공급된 고압의 공기는 공기주입관(40)을 통해 공기주입용부시(30)의 공기유입공간(32)으로 공급되고, 공기유입공간(32)과 소통하는 공기유입공(22)을 통해 공기가 중공축(20)의 내부공간으로 유입되며 중공축(20)의 공기배출공(24)을 통해 공기분사관(60)으로 공기가 유입된다. As shown in Figure 6, the water filtration device according to the present invention is a high pressure air supplied by the air supply means 42 from the outside of the water filtration tank (1) for the air injection through the air injection pipe (40) The air is supplied to the air inlet space 32 of the bush 30, and the air is introduced into the internal space of the hollow shaft 20 through the air inlet hole 22 communicating with the air inlet space 32 and the hollow shaft 20. Air is introduced into the air injection pipe 60 through the air discharge hole 24 of the.
공기분사관(60)의 단부에서 분사된 고압의 공기는 차폐판(10)의 통과공(11)을 거쳐 여과사내장형스크린(70)의 여과사(79)로 침투한다. 이 때 역세수배출관(50)과 차폐판(10)의 사이에서 차폐판(10)에 밀착하도록 스프링(56) 지지되는 원주상측면커버(55)가 위치하므로 분사된 공기는 누설되지 않고 대부분 여과사(79)로 침투하게 된다.The high pressure air injected from the end of the air injection pipe 60 penetrates through the through hole 11 of the shielding plate 10 and into the filter yarn 79 of the filter-embedded screen 70. At this time, since the circumferential side cover 55, which is supported by the spring 56, is positioned between the backwash water discharge pipe 50 and the shielding plate 10 so as to be in close contact with the shielding plate 10, the injected air is not leaked and is mostly filtered. Will penetrate the yarn (79).
여과사(79)로 침투한 공기는 여과사(79)들 사이의 간격을 확장시키는 역할을 하며 여과사내장형스크린(70)을 거쳐 배출용수저장부(3)로 이동한 공기는 배출되는 용수와 함께 용수배출관(5)을 통해 용수여과탱크(1)의 외부로 배출된다.Air penetrated into the filter sand (79) serves to extend the gap between the filter sand (79) and the air moved to the discharge water storage unit (3) through the built-in filter screen 70, the discharged water and Together with the water discharge pipe (5) is discharged to the outside of the water filtration tank (1).
도 7은 본 발명의 바람직한 실시예에 따른 여과사내장형스크린을 구비한 용수여과장치에서 분사공기에 의해 여과사내장형스크린의 내부의 여과사들 사이의 간격변화를 도시한 도면이다.7 is a view showing a change in the interval between the filter yarns in the interior of the filter-embedded screen by the injection air in the water filtering device having a filter-embedded screen in accordance with a preferred embodiment of the present invention.
도 7에 도시된 바와 같이, 공기분사관(60)을 통해 여과사내장형스크린(70)의 내부로 침투한 고압의 공기는 여과사(79)들에 압력을 가하여 여과사(79)들 사이의 간격이 확장된다. 여과사(79)들 사이의 간격이 확장됨에 따라 여과사내장형스크린(70)의 내부공간을 여과사(79)가 점유하는 영역 또한 확장된다. 여과사내장형스크린(70)에는 여유공간이 형성되어 있기 때문에 여과사(79)들 사이의 간격이 확장될 수 있는 공간이 마련된다.As shown in FIG. 7, the high-pressure air that penetrates into the inside of the filtration-embedded screen 70 through the air injection pipe 60 exerts a pressure on the filtration yarns 79 to form a gap between the filtration yarns 79. The interval is extended. As the distance between the filter yarns 79 is expanded, the area occupied by the filter yarns 79 also extends to the internal space of the filter-coated screen 70. Since the free space is formed in the filter-embedded screen 70, a space in which the space between the filter yarns 79 is extended is provided.
따라서 여과사(79)들 사이에 끼워져서 여과사(79)들 사이에 머무르던 이물질(100)들은 여과사(79)들 사이의 간격이 확장되면서 이동할 수 있는 통로가 마련되며, 역세과정에서 역세수배출관(50)으로 배출되는 역세용수에 휩쓸려서 역세용수와 함께 용수여과탱크(1)의 외부로 배출된다. Therefore, the foreign matter 100 that is sandwiched between the filter yarns 79 and stayed between the filter yarns 79 is provided with a passage through which the gap between the filter yarns 79 is extended, and the backwashing water in the backwashing process is provided. It is swept away by the backwash water discharged to the discharge pipe 50 and discharged to the outside of the water filtration tank 1 together with the backwash water.
도 8은 본 발명의 바람직한 실시예에 따른 여과사내장형스크린을 구비한 용수여과장치에서 역세시의 용수의 흐름을 표시한 도면이다. 8 is a view showing the flow of water during backwashing in the water filtration device having a built-in filtration screen according to a preferred embodiment of the present invention.
도 8에 도시된 바와 같이, 역세과정에서 역세수배출관(50)은 역세를 수행할 여과사내장형스크린(70)이 설치된 차폐판(10)의 통과공(11) 아래로 이동하여 위치한다. As shown in FIG. 8, in the backwashing process, the backwash water discharge pipe 50 moves and moves below the through-hole 11 of the shielding plate 10 in which the in-house filtered screen 70 for backwashing is installed.
역세과정이 시작될 때에는 역세수배출관(50)에 형성된 밸브(미도시)가 열리면서 역세수배출관(50)의 외부공기측 단부는 대기압에 노출된다. 한편 용수여과탱크(1)의 배출용수저장부(3)의 압력은 펌프(9)에 의해 가압되어 유입용수저장부(2)로 진입한 용수의 압력과 거의 유사하므로 대기압보다 훨씬 큰 압력을 갖는다.When the backwashing process starts, a valve (not shown) formed in the backwashing water discharge pipe 50 is opened, and the external air side end of the backwashing water discharge pipe 50 is exposed to atmospheric pressure. On the other hand, the pressure of the discharge water storage unit 3 of the water filtration tank 1 has a pressure much higher than atmospheric pressure because it is almost similar to the pressure of the water pressurized by the pump 9 and entering the inflow water storage unit 2. .
따라서 이러한 배출용수저장부(3)의 압력과 대기압의 압력차에 의해 배출용수저장부(3)에 저장된 용수중에서 역세가 수행되는 여과사내장형스크린(70)에 인접한 영역에 있는 용수부터 우선적으로 여과사내장형스크린(70)을 통해 역세수배출관(50)으로 배출되게 된다. Therefore, the filtration is preferentially performed from the water in the region adjacent to the filtration-embedded screen 70 where backwashing is performed in the water stored in the discharge water storage unit 3 by the pressure difference between the pressure of the discharge water storage unit 3 and the atmospheric pressure. It is discharged to the backwash water discharge pipe 50 through the in-house screen 70.
도 6 및 도 7을 통해 설명한 바와 같이, 역세과정에서는 역세를 수행하는 여과사내장형스크린(70)으로 공기분사관(60)을 통해 고압의 공기가 분사되어 여과사(79)들 사이의 간격이 확장되므로, 이 때 역세수배출관(50)으로 배출되는 용수가 여과사(79)들 사이에 머무르던 이물질(100)들을 휩쓸어서 역세수배출관(50)으로 배출시키게 된다. 하나의 여과사내장형스크린(70)에 대한 역세가 완료되면 역세수배출관(50)이 모터(7)에 의해 이동하여 여과사내장형스크린(70)의 역세를 수행할 수 있다.As described above with reference to FIGS. 6 and 7, in the backwashing process, high pressure air is injected through the air injection pipe 60 to the built-in filtration screen 70 for backwashing, so that the gap between the filtration yarns 79 is increased. Since it is expanded, the water discharged to the backwash water discharge pipe 50 is swept away the foreign matter 100 that remained between the filter yarns 79 to be discharged to the backwash water discharge pipe 50. When the backwashing is completed for one of the built-in filtration screen 70, the backwash water discharge pipe 50 may be moved by the motor 7 to perform backwashing of the filtration-built screen 70.
이 때 하나의 여과사내장형스크린(70)에서는 역세가 이루어지지만 다른 여과사내장형스크린(70)들에서는 여전히 여과가 수행된다. 따라서 배출용수저장부(3)에 위치하는 용수의 일부는 역세수배출관(50)으로 배출되지만 나머지 일부는 용수배출관(5)으로 배출된다. 따라서 본 발명에 따른 용수여과장치는 용수를 여과하는 과정을 중단하지 않고 여과사내장형스크린(70)들을 차례차례 역세하여 세척할 수 있는 것이다.At this time, backwashing is performed in one filtration-embedded screen 70, but filtration is still performed in other filtration-embedded screens 70. Therefore, a part of the water located in the discharge water storage unit 3 is discharged to the backwash water discharge pipe 50, but the other part is discharged to the water discharge pipe (5). Therefore, the water filtration device according to the present invention can be washed by sequentially backwashing the filtration in-house screen 70 without interrupting the process of filtering the water.
역세과정의 시작은 유입용수관 및 용수배출관(5) 각각에 압력센서들(미도시)을 설치하고 각각에 설치된 압력센서들의 측정값에 일정값 이상의 차이가 발생시 이루어지도록 설정할 수 있다.The start of the backwashing process may be set so that pressure sensors (not shown) are installed in each of the inflow water pipe and the water discharge pipe 5, and a difference occurs by a predetermined value or more in the measured values of the pressure sensors installed in the water pipes.
본 발명에 따른 용수여과장치의 여과사내장형스크린(70)은 하부에 쐐기형와이어스크린(76)이 형성되므로, 쐐기형와이어스크린(76)이 여과사(79)에 진입하기 이전에 용수를 예비적으로 걸러주게 되어 여과사(79)들에게 과도한 부담을 주지 않는다.Since the filtered yarn built-in screen 70 of the water filtration device according to the present invention has a wedge-shaped wire screen 76 formed at a lower portion thereof, the wedge-shaped wire screen 76 reserves water before entering the filter sand 79. It will be filtered by the enemy does not put excessive strain on the filter yarn (79).
상기 실시예에서 여과사내장형스크린(70)의 와이어메시스크린(74)부 내측에 구조적 형태를 유지시키도록 타공판이 형성된 이유는 와이어메시스크린(74)이 매우 유연하여 구조적 형상을 유지하기 어렵기 때문이다.In the above embodiment, the perforated plate is formed to maintain the structural shape inside the wire mesh screen 74 of the filtration-embedded screen 70 because the wire mesh screen 74 is very flexible and difficult to maintain a structural shape. to be.
상기 실시예에서는 공기주입관(40)으로 공기를 공급하기 위해 공기탱크와 같은 공기공급수단(42)을 사용하였으나, 본 발명은 이에 제한되지 않고 송풍기 등과 같은 공기공급수단을 사용하는 것도 가능하다.In the above embodiment, an air supply means 42 such as an air tank is used to supply air to the air injection pipe 40. However, the present invention is not limited thereto, and an air supply means such as a blower may be used.
