Description

여과지 표면세척장치{Surface washing apparatus for filter basin}Surface washing apparatus for filter basin

본 발명은 정수장의 여과지의 표면을 세척하기 위한 표면세척장치에 관한 것으로, 특히 여과사의 높이에 따라 표면세척장치의 높낮이를 조절할 수 있도록 하는 여과지 표면세척장치에 관한 것이다.The present invention relates to a surface cleaning device for cleaning the surface of the filter paper of the water purification plant, and more particularly, to a filter paper surface cleaning device to adjust the height of the surface cleaning device according to the height of the filter sand.

일반적으로 정수장은 유입되는 물을 정수하여 공급하는 시설로서, 물에 포함된 이물질 등을 제거하기 위하여 여과지를 통과시키게 된다.In general, a water purification plant is a facility for purifying and supplying inflowing water, and passing filter paper to remove foreign substances in water.

여과지는 바닥으로부터 상측방향으로 크기가 다른 입자로 된 여과층이 적층되도록 설치되는데, 가장 바닥부에는 비교적 입자가 큰 자갈 형태의 제1여과층이 구비되고, 그 상측으로는 제1여과층보다 입자가 작은 자갈로 된 제2여과층이 적층된다.The filter paper is installed so that a filtration layer of particles of different sizes is stacked upward from the bottom, and the bottom portion is provided with a first filtration layer in the form of a gravel having a relatively large particle, and at the upper side thereof, particles are larger than the first filtration layer. The second filtration layer of small pebbles is laminated.

또한 제2여과층으로 상측으로는 모래와 같은 아주 미세한 입자의 제3여과층이 적층되어, 제3여과층의 상부로부터 물을 유입받아 여과시켜 여과지의 바닥부를 통해 배출하는 것이다.In addition, a third filtration layer of very fine particles such as sand is stacked on the upper side of the second filtration layer, and water is introduced from the upper portion of the third filtration layer and filtered to be discharged through the bottom of the filter paper.

이때, 제3여과층의 상부표면에는 물에 포함된 이물질이 가장 많이 고착되어 여과 효율을 떨어뜨리므로, 이를 주기적으로 세척하여 주어야 하는데, 이를 위해 제3여과층의 상부로 고압의 세척수를 분사시켜 고착된 이물질을 털어내도록 하는 표면세척장치가 구비된다.At this time, since the foreign matter contained in the water is most fixed to the upper surface of the third filtration layer to reduce the filtration efficiency, it should be cleaned periodically. A surface cleaning device is provided to shake off the stuck foreign matter.

그런데, 이러한 표면세척장치는 통상적으로 여과지의 구조물에 고정지지되는데, 그 설치되는 높이까지 고정된 상태로 구성되어 각 여과층의 높이가 달라지는 경우 효율적인 표면 세척이 이루어질 수 없다.By the way, such a surface cleaning device is usually fixed to the structure of the filter paper, it is configured in a fixed state up to the height of the installation is not effective surface cleaning can be made when the height of each filter layer is different.

즉, 물의 정수 정도 또는 시간 당 정수량의 변화를 위하여 제1, 제2, 제3여과층의 두께를 다르게 하면 표면세척장치와의 거리도 달라지게 되는데, 제3여과층의 표면과 표면세척장치와의 거리가 멀어진 경우 분사된 세척수가 압력을 유지하면서 제3여과층에 도달하지 못하므로 세척효율이 저하되고, 반면에 너무 가까우면 고압의 세척수에 의해 제3여과층의 모래가 유실되는 경우가 발생하는 문제점이 있다.In other words, if the thickness of the first, second, and third filtration layers is changed in order to change the purified water or the amount of purified water per hour, the distance from the surface cleaning device is also changed. If the distance is far, the sprayed washing water does not reach the third filtration layer while maintaining the pressure, so the washing efficiency is lowered. On the other hand, if the water is too close, the sand of the third filtration layer is lost by the high pressure washing water. There is a problem.

이와 같은 종래의 문제점을 해결하기 위하여 본 발명은 표면세척장치의 높낮이를 조절할 수 있도록 하여 여과층의 표면과 일정 간격을 유지하도록 함으로써 최적의 표면 세척이 이루어질 수 있도록 하는 여과지 표면세척장치에 관한 것이다.In order to solve such a conventional problem, the present invention relates to a filter paper surface cleaning device that can be adjusted to the height of the surface cleaning device to maintain a certain distance from the surface of the filter layer to achieve an optimal surface cleaning.
