Description
본 발명은 여과조의 여재 부유율 측정장치에 관한 것으로, 더욱 상세하게는 여재에 함유되어 있는 이 물질을 효과적으로 수거하고 또 고가의 여재가 유실되는 것을 방지하는 여과조의 여재 부유율 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring the median floatation rate of a filtration tank, and more particularly, to an apparatus for measuring the median floatation rate of a filtration tank, which effectively collects this substance contained in the media and prevents expensive media from being lost.
일반적으로 상수원으로부터 물을 공급받아 혼화→응집→침전→여과→정수 그리고 송수 등의 공정을 일괄적으로 취하는 정수장(또는 수원지)에는 정수의 전 단계로 여과공정을 하게 된다.In general, a water purification plant (or water source) that receives water from a water supply source and mixes, aggregates, sediments, filtration, purified water, and water in a lump is subjected to filtration in all stages of water purification.
도 1에는 여과공정을 행하는 일반적인 여과조의 내부 구조를 보인 예시도가 도시되어 있다.1 is an exemplary view showing the internal structure of a general filtration tank for performing the filtration step.
도시된 바와 같이, 여과조(10)의 내부에는 입자 형상을 갖는 여재(또는 활성탄)(20)와 모래 그리고 자갈이 적층되고, 침전 등의 전 공정으로부터 물을 공급받거나 후술하는 이 물질을 배출시키는 트러프(Trough)(30)가 배치되고 내부 하측에는 여재(20)를 통과한 물을 약품이 첨가되는 다음 공정인 정수조로 송수시키거나 후술하는 역세수가 유입되는 관체(40)가 배열된다.As shown, inside the filter tank 10, the media (or activated carbon) 20 having a particle shape, sand and gravel are stacked, and water is supplied from the entire process such as sedimentation or discharge of this material, which will be described later. A rough (Trough) 30 is arranged and the lower side of the inner body 40 is arranged to send water passed through the filter medium 20 to the water purification tank, which is the next step of adding the chemicals, or the backwash water introduced later.
또 트러프(30)의 하측에는 후술하는 여재(20)의 상측면에 쌓이게 되는 이물질을 세척하기 위한 세척수를 공급하기 위한 세척수 공급관(50)이 배열된다.In addition, the washing water supply pipe 50 for supplying the washing water for washing the foreign matter accumulated on the upper side of the filter medium 20 to be described later is arranged below the trough 30.
따라서, 침전 등의 공정을 마친 후 트러프(30)를 통하여 유입된 물은 여과조(10)의 내부에 담겨진 여재(20) 들 사이를 통하여 통과되며 이 물질 등이 걸러지고, 그와 같이 이 물질이 걸러진 물은 관체(40)를 통하여 여과조(10)를 통과한 후 다음공정인 정수공정의 정수조로 유입되어 정수조 내에서 최종적으로 약품이 첨가된 상태에서 가정용 식수로 송수된다.Therefore, the water introduced through the trough 30 after the process of precipitation and the like is passed through the filter medium 20 contained in the interior of the filter tank 10, the material is filtered, and so on The filtered water passes through the filtration tank 10 through the pipe 40, and then flows into the water purification tank of the next water purification process, which is finally delivered to the domestic drinking water in the state where the chemicals are finally added in the water purification tank.
한편, 여과조의 내부에 담겨진 여재는 입자 형태의 물질들이 쌓여져 구성되고 그 입자들 사이로 침전공정을 통과한 물이 통과되며 물에 함유된 이 물질들이 걸러지게 되므로 여재(20)는 일정한 기간을 두고 역세공정이라는 공정에 의해 세척을 해야 한다.On the other hand, the filter medium contained in the interior of the filter tank is formed by the accumulation of particles in the form of particles, and the water passing through the settling process is passed between the particles, the filter material 20 is backwashed for a certain period of time because these substances contained in the water are filtered out. It should be cleaned by a process called process.
즉, 여과조(10)는 사용기간이 지속될수록 침전조에서 제거되지 않은 이물질 등이 쌓이게 되고 그에 따라 여재(20)는 이물질에 대한 여과기능이 저하되므로 여과능력이 현저히 떨어지게 된다.That is, as the filter tank 10 continues to be used, foreign matters that are not removed from the sedimentation tank are accumulated, and thus, the filter medium 20 is degraded in filtration function due to the deterioration of the filtration function.
따라서, 이때에는 상기의 역순으로 관체(40)를 통하여 공급받는 물을 상측으로 분출시키게 되면 여재가 부유되고, 여재가 부유된 만큼 여재의 밀도가 넓어지게 됨으로써 그 사이에 끼어 있는 이 물질을 물과 함께 부유시키게 된다.Therefore, at this time, if the water supplied through the pipe 40 in the reverse order to the upper side to eject the media is suspended, the density of the media becomes wider as the media is suspended, the water sandwiched between the water and Floated together.
즉, 관체(40)로부터 물이 공급되면 그 물의 분출력에 의해 여재(20)는 부유되고 그와 같이 부유되는 여재(20)의 사이에 낀 이물질은 관체를 통하여 공급받은 물과 함께 부유되며 유로의 기능을 하는 트러프(30)를 매개로 설정된 경로를 통하여 배수된다.That is, when water is supplied from the tubular body 40, the mediator 20 is suspended by the split power of the water, and foreign substances caught between the mediators 20 that are suspended are suspended together with the water supplied through the tubular body. Drain through the path set through the trough 30 to function as.
그러나, 상기와 같은 역세공정 중에는 다음과 같은 문제점이 발생된다.However, the following problems occur during the backwashing process as described above.
즉, 여재의 부유율(또는 팽창률)이 여재의 적층률에 비해 20% 이하가 되면 이 물질을 부유시켜 제거하기가 곤란하고 부유율이 30%를 초과하게 되면 여재가 유실되기 쉬운 문제점이 발생하게 된다.That is, when the median floatation rate (or expansion rate) is less than 20% of the median stacking rate, it is difficult to float and remove this material, and when the median flow rate exceeds 30%, the mediators tend to be lost. do.
그러나, 지금 까지는 별도의 여재 부유율 측정장치 등이 제안되고 있지 않아 정확하게 여재의 부유율을 측정할 수 없는 문제점이 발생되었다.However, until now, a separate media float rate measuring device has not been proposed, and thus a problem arises in that the media cannot be accurately measured.
따라서, 여재에 함유되어 있는 이 물질을 효과적으로 수거하지 못하거나 또는 많은 고가의 여재를 유실시킬 수밖에 없는 구조적인 문제점이 있었다.Therefore, there is a structural problem that can not effectively collect this material contained in the media or to lose a lot of expensive media.
따라서 본 발명이 해결하고자 하는 기술적 과제, 즉 본 발명의 목적은 종래와 같은 여과조의 여재 세척시 발생되었던 구조적인 문제점을 해결하기 위한 것으로, 여재의 부유율(또는 팽창률)을 정확히 측정토록 함으로써 여재에 함유된 이 물질을 효과적으로 제거함은 물론 여재의 유실을 방지하는 여과조의 여재 부유율 측정장치를 제공하는데 있다.Therefore, the technical problem to be solved by the present invention, that is, the object of the present invention is to solve the structural problems that occurred when the filter medium of the filter media as in the prior art, by measuring the suspension (or expansion rate) of the filter media to accurately The present invention provides an apparatus for measuring the median floatation rate of a filtration tank that effectively removes the substance contained therein and prevents loss of media.

It may be installed.
상기와 같이 구성된 본 발명에 따른 측정장치의 동작에 대해 설명한다.The operation of the measuring device according to the present invention configured as described above will be described.
즉 본 발명이 적용되는 여과지와 여과지에 대한 역세공정은 종래의 기술에서설명한 바와 동일하므로 이에 대한 별도의 설명은 생략하기로 하고 다만 본 발명의 특징부에 대해서만 한정하여 설명하기로 한다.That is, the backwashing process for the filter paper and the filter paper to which the present invention is applied is the same as described in the prior art, so a separate description thereof will be omitted and only limited to the features of the present invention.
즉, 본 발명에 따른 측정장치를 도 5와 같이 설치한 상태에서 종래와 마찬가지로 역세공정을 하게 되면 관체(40)를 통하여 유입된 물은 상측으로 분출하게 되고, 그와 같이 분출되는 물에 의해 여재(20)가 부유되고, 여재(20)가 부유된 만큼 여재(20)의 밀도가 넓어지게 됨으로써 그 사이에 끼어 있는 이 물질을 물과 함께 부유시키게 된다.That is, when the backwashing process as in the prior art in the state in which the measuring device according to the present invention is installed as shown in FIG. 5, the water introduced through the pipe body 40 is ejected to the upper side, and the media is discharged by the water jetted as such. As the 20 is suspended and the media 20 is suspended, the density of the media 20 is widened so that this substance sandwiched therebetween is suspended together with water.
또 그와 같이 부유되는 여재(20)의 사이에 끼었던 이물질은 관체(40)를 통하여 공급받은 물과 함께 부유되며 유로의 기능을 하는 트러프(30)를 매개로 설정된 경로를 통하여 종래와 동일하게 배수된다.In addition, the foreign matter sandwiched between the media (20) to be suspended as described above through the path set through the trough 30, which is suspended with the water supplied through the tube 40 and functions as a flow path.

그러나, 이때 본 발명의 특징부는 상기와 같은 일련의 역세공정을 진행하는 동안에 도 6의 예시도와 같이 여재(20)가 물과 함께 부유(또는 팽창)하게 되면 이 여재(20)는 본 발명에 따른 상측이 개방되며 각각 다른 높이의 단차를 갖고 설치된 측정조(60)의 내측으로 유입하게 된다.However, the feature of the present invention is that the filter medium 20 is suspended (or expanded) with water as shown in Figure 6 during the series of backwashing process as described above, the filter medium 20 according to the present invention The upper side is opened and flows into the inside of the measuring tank 60 provided with the step of each different height.
따라서, 물과 함께 부유한 후 각각 다른 높이를 갖고 설치된 측정조(60)의 내측으로 쌓이게 되는 여재(20)의 적층률을 식별하여 가장 효과적인 여재의 부유율을 측정할 수 있게 된다.Therefore, the floating rate of the most effective medium can be measured by identifying the stacking rate of the medium 20 stacked on the inside of the measuring tank 60 installed with different heights after floating with water.
결과적으로, 여재의 부유율이 여재의 적층률에 비해 20%∼30%의 범위 내를 효과적으로 유지시킬 수 있게 된다.As a result, the suspension ratio of the media can be effectively maintained in the range of 20% to 30% compared to the stacking ratio of the media.
이상에서 상세히 설명한 바와 같이 본 발명에 따른 여과조의 여재 부유율 측정장치에 의하면, 여재에 함유되어 있는 이 물질을 효과적으로 수거하지 못하거나 또는 많은 고가의 여재를 유실시킬 수밖에 없었던 종래의 문제점을 해결하게 된다.As described in detail above, according to the apparatus for measuring the median floatation rate of the filtration tank according to the present invention, it is possible to solve the conventional problems in which this material contained in the media cannot be effectively collected or many expensive media have to be lost. .
지금까지는 본 발명에 따른 바람직한 실시예들에 대하여 한정하여 도시하고 설명하였지만 이에 한정되지 않고 당 분야에서 통상의 지식을 가진 자에 의해 다양하게 변경 사용이 가능하다.Until now illustrated and described with respect to the preferred embodiments according to the present invention, but not limited to this can be variously changed and used by those skilled in the art.
