Description
본 발명은 자력을 이용하여 자성체가 포함된 폐수를 처리하는 장치에 관한 것으로, 구체적으로 자성체가 포함된 폐수를 마그네틱 필터를 이용하여 처리하는 폐수처리장치에 관한 것이다.The present invention relates to an apparatus for treating wastewater containing a magnetic substance using magnetic force, and more particularly, to a wastewater treatment apparatus for treating wastewater containing a magnetic substance by using a magnetic filter.
일반적으로 여과기를 이용한 폐수처리장치는 도 1에 도시된 바와 같이, 폐수원수조(10)로부터의 폐수가 폐수공급펌프(11)에 의해 여과기(14)에 공급되고, 여과기(14)에 투입된 폐수는 내부에 설치된 분리막을 통과하면서 여과되고 이 여과된 처리수는 밖으로 배출되어 여과액수조(12)에 저장된다. 여과기내의 분리막을 세정할 때는 세정용 압축공기(15)를 분리막에 쐬어 세정하고, 그 세정한 불순물이 포함된 농축액은 농축액 저장조(13)로 이송되어 저장된다.In general, the wastewater treatment apparatus using the filter, as shown in Figure 1, the wastewater from the wastewater source tank 10 is supplied to the filter 14 by the wastewater supply pump 11, the wastewater introduced into the filter 14 Is filtered while passing through a separator installed therein, and the filtered treated water is discharged outward and stored in the filtrate tank 12. When the separation membrane in the filter is washed, the compressed compressed air 15 for washing is poured into the separation membrane, and the concentrated liquid containing the washed impurities is transferred to the concentrated liquid storage tank 13 and stored.
또한, 일반적으로 자성유체분리탑(20)을 이용한 폐수처리장치는 도 2에 도시된 바와 같이, 폐수원수조(10)로부터의 폐수가 폐수공급펌프(11)에 의해 자성유체분리탑(20)에 공급되고, 공급된 폐수는 외부벽면에 자석(21)이 설치되어 있는 자성유체분리탑(20)을 통과하면서 이 자석의 자력에 의하여 폐수에 포함된 자성체가 분리되어 자성유체분리탑(20)의 벽면에 부착되므로써 폐수의 불순물이 여과처리되고, 이와 같이 여과 처리된 여과수는 밖으로 배출되어 여과액 수조(12)에 저장된다. 자성유체분리탑(20)에 부착된 불순물을 세정할 때에는 전자석 형태의 자석에 전류를 차단시켜 자성을 없앤 후 자성유체분리탑내의 유체의 흐름을 폐수여과처리시와 반대로 하여 세정하고, 그 세정한 불순물이 포함된 농축액은 농축액저장조(13)에 저장된다.In addition, in general, the wastewater treatment apparatus using the magnetic fluid separation tower 20, as shown in Figure 2, the wastewater from the wastewater source water tank 10 by the wastewater supply pump 11, the magnetic fluid separation tower 20 The supplied waste water passes through the magnetic fluid separation tower 20 having the magnet 21 installed on the outer wall thereof, and the magnetic material contained in the waste water is separated by the magnetic force of the magnet, thereby separating the magnetic fluid separation tower 20. Impurities in the wastewater are filtered by being attached to the wall surface of the wastewater, and the filtered water thus filtered is discharged outward and stored in the filtrate tank 12. When cleaning the impurities attached to the magnetic fluid separation tower 20, the magnets in the form of electromagnets are cut off to remove the magnetism, and then the flow of the fluid in the magnetic fluid separation tower is washed in the reverse direction of the waste water filtration treatment. The concentrate containing impurities is stored in the concentrate storage tank 13.
그러나, 상기에서 여과기(14)만으로 폐수를 처리하는 경우에는, 분리막의 작은 구멍으로 폐수가 여과되기 때문에 구멍이 쉽게 막힐 우려가 있어 빈번한 세정이 필요할 뿐아니라 이에 따라 높은 압력으로 폐수를 공급해야 하기 때문에 이를 운전하기 위한 설비비 및 운전비가 과다하게 지출되는 문제점이 있었다. 또한, 자성유체분리탑(20)을 이용하여 폐수를 처리하는 경우에는, 자성유체분리탑(20)의 외벽에 설치되어 있는 자석의 자기력은 자석부근에서만 강하게 나타나므로 그 자기력이 미치는 범위가 극히 작아 기기의 크기를 일정 규모 이상으로 할 수 없어 기기의 크기가 제한을 받는 문제점이 있었다.However, in the case where the wastewater is treated only with the filter 14, since the wastewater is filtered through the small holes of the separation membrane, the holes may be easily clogged, which requires frequent cleaning, and accordingly, the wastewater must be supplied at a high pressure. There was a problem in that the equipment cost and the operating cost for driving this excessively. In addition, when the wastewater is treated using the magnetic fluid separation tower 20, the magnetic force of the magnet installed on the outer wall of the magnetic fluid separation tower 20 is strong only near the magnet, so the range of the magnetic force is extremely small. There was a problem that the size of the device is limited because the size of the device can not be more than a certain size.
따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 그 목적은 자력을 이용하여 자성체가 포함된 불순물을 함유하는 폐수를 처리하는 것으로서, 특히 마그네틱 필터를 이용하므로써 유체저항을 최소화하고 상업화설비가 가능한 규모의 기기를 이용하여 폐수를 처리하여 깨끗한 여과수를 생산하므로써 이를 재이용 또는 방류할 수 있는 마그네틱 필터를 이용한 폐수처리장치를 제공하는 것이다.Therefore, the present invention has been made in order to solve the above problems, the purpose is to treat the wastewater containing impurities containing magnetic material by using a magnetic force, in particular by using a magnetic filter to minimize the fluid resistance and commercialization facilities It is to provide a wastewater treatment apparatus using a magnetic filter that can be reused or discharged by producing clean filtered water by treating the wastewater using a scaleable device.

A wastewater treatment apparatus using a magnetic filter cleaned by a washing water spraying apparatus is provided.
이하에 본 발명의 실시예를 도면을 참고로 좀 더 상세히 설명한다. 도 3에 도시된 바와 같이, 본 발명에 의한 폐수처리장치에 의하면, 폐수원수조(10)에 저장된 폐수가 폐수공급펌프(11)에 의해 이송배관을 통하여 폐수를 여과처리하는 부분인 마그네틱 필터탑(30)에 이송되고, 여기에서 하부에서 상부로 이송되는 동안 자기력을 띤 마그네틱 필터(33)에 의해 폐수에 포함된 자성 부유물질이 제거되고, 이에 의해 여과된 여과수는 밖으로 배출되어 여과액수조(12)에 저장된다. 이와 같은 여과처리 과정이 여러번 반복됨에 따라 마그네틱 필터에 부착된 자성부유물질의 양이 과다하게 되면 폐수공급펌프(11)를 정지시키고, 세정수 공급펌프(31)에 의해 여과액 수조(12)에 담긴 여과액이 마그네틱 필터탑(30)에 공급되고 세정수스프레이노즐(32)을 통해 배출되어 마그네틱필터(33)에 부착된 자성 부유물질을 제거한다. 이 세정처리시에는, 전자석형태로 되어 있는 마그네틱필터(33)에 전류를 차단하여 자성을 없애므로 마그네틱필터(33)에 부착된 불순물이 쉽게 제거될 수 있다. 이와같이 마그네틱필터(33)를 세정한 불순물을 포함하는 농축액은 농축액 이송펌프(34)에 의해 농축액 저장조(13)로 이송되어 저장된다. 이 마그네틱필터를 이용하므로써 유체의 저항이 적어 소규모 장치로 대용량의 폐수를 깨끗이 여과처리하여 세정수로서 재이용하거나 방류할 수 있는 마그네틱 필터를 이용한 폐수처리장치가 제공된다.Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings. As shown in Figure 3, according to the wastewater treatment apparatus according to the present invention, the magnetic filter tower which is a part of the wastewater stored in the wastewater source tank 10 to filter the wastewater through the transfer pipe by the wastewater supply pump 11 The magnetic suspended solids contained in the wastewater are removed by the magnetic magnetic filter 33, which is transferred to the 30, from the lower part to the upper part, and the filtered filtrate is discharged outwards so that the filtrate tank ( 12). As such a filtration process is repeated several times, if the amount of magnetic flotation material attached to the magnetic filter becomes excessive, the wastewater supply pump 11 is stopped and the filtrate tank 12 is washed by the washing water supply pump 31. The contained filtrate is supplied to the magnetic filter tower 30 and discharged through the washing water spray nozzle 32 to remove the magnetic suspended solids attached to the magnetic filter 33. In this cleaning process, the magnetic filter 33, which is in the form of an electromagnet, cuts off current to eliminate magnetism, so that impurities attached to the magnetic filter 33 can be easily removed. Thus, the concentrated liquid containing the impurity which cleaned the magnetic filter 33 is transferred to the concentrate storage tank 13 by the concentrate transfer pump 34, and is stored. The use of the magnetic filter provides a wastewater treatment apparatus using a magnetic filter that can be reused or discharged as washing water by filtering large volumes of wastewater cleanly with a small device due to low fluid resistance.
상술한 바와 같은 구성을 갖는 본 발명에 의하면, 자성체가 포함된 폐수를 처리함에 있어서 유체의 저항이 적은 마그네틱 필터를 이용하므로써 소규모 장치로 대용량의 폐수를 처리할 수 있을 뿐아니라 세정시간을 최소화하여 소량의 농축액을 얻을 수 있고 자성체를 부착하는 자기력이 크기 때문에 유량변동에 적응성이 쉬울 뿐아니라 온도, 압력 등의 폐수의 조건에 능동적으로 대처가 가능하므로 설비비 및 운전비를 타설비에 비하여 현저히 줄일 수 있는 효과가 있다.According to the present invention having the configuration as described above, by using a magnetic filter with a low resistance of the fluid in the treatment of wastewater containing a magnetic substance, it is possible to treat a large amount of wastewater with a small-scale device as well as to minimize the cleaning time to a small amount It is possible to obtain a concentrated liquid and to have a large magnetic force to attach magnetic material, so that it is easy to adapt to flow fluctuations and can cope actively with the conditions of wastewater such as temperature and pressure, so that the equipment cost and operation cost can be significantly reduced compared to other equipment.
