Description
본 발명은 부직포 섬유필터 및 그 가공방법에 관한 것으로, 구체적으로 초기우수에서 기름성분 및 토사성분과 같은 비점오염물질을 제거하는데 사용하는 나비형상의 부직포 필터에 관한 것이다.The present invention relates to a nonwoven fabric filter and a processing method thereof, and more particularly, to a butterfly-shaped nonwoven fabric filter used for removing nonpoint pollutants such as oil and earth and sand components from initial rainwater.
일반적으로 초기우수처리를 위해 처리조로 유입되는 기름성분 및 비점오염물질들로부터 초기우수 속에 함유되어 있는 유분(油分) 또는 미세한 부유물질을 비롯한 고형물을 분리하기 위한 초기우수처리시설(비점오염저감시설)은 기름과 고형물의 비중차에 의해 제거하는 방법과, 유입 처리수의 원심력을 이용한 볼텍스원리 및 일라이트, 제오라이트, 피트모스 등의 여과재를 사용한 여과방법을 사용하고 있다.In general, an initial excellent treatment facility (non-point pollution abatement facility) for separating solids, including oil or fine suspended solids, contained in the initial rainwater from oil components and nonpoint pollutants introduced into the treatment tank for initial rainwater treatment. It removes by the difference of specific gravity of silver oil and solids, and the vortex principle which uses the centrifugal force of inflow process water, and the filtration method using filter materials, such as an illite, a zeolite, a peat moss, are used.
그러나 볼텍스원리를 이용한 처리방법은 깡통, 우유팩, 낙엽, 비닐조각과 같은 입자가 큰 고형물의 제거는 가능하지만, 대부분의 미세 부유물질은 통과되기 때문에 처리효율이 떨어진다는 단점이 제기되고 있으며, 일라이트, 제오라이트, 피트모스 등의 여과재를 사용한 여과방법은 처리효율은 높은 편이나 여과재의 입자크기가 3 ~ 5mm 정도의 크기로서 공극률이 떨어져 처리수가 여과재를 통과할 때 유체저항을 많이 받게 되며, 자연적인 흐름으로 처리수 관을 흐르는 처리수를 처리하기 위해서는 상대적으로 여과선속도가 낮아지는 이유로 인해 500 ㎥/hr 이상의 처리시설에는 대규모의 처리시설 면적이 소요되므로 경제성이 떨어진다는 단점이 제기되고 있다.However, the treatment method using the vortex principle is capable of removing solid particles such as cans, milk cartons, fallen leaves, and pieces of vinyl, but it is disadvantageous that most of the fine suspended solids pass through, resulting in poor treatment efficiency. Filtration method using filter media such as light, zeolite, pit moss, etc. has high treatment efficiency, but the particle size of filter media is about 3 ~ 5mm, and the porosity is low, so that the treated water receives a lot of fluid resistance when passing through the filter media. In order to treat the treated water flowing through the treated water pipe as a flow, due to the relatively low filtration line speed, processing facilities of 500 m3 / hr or more require a large treatment facility area, which is disadvantageous in that the economy is inferior.
특히 기존의 일라이트, 제오라이트, 피트모스 등의 여과재를 사용한 여과방법은 여과재 입자가 딱딱한 고체성질로 여과선속도가 떨어지고 흡수력이 떨어지게 되므로 기름성분의 경우 처리유속에 의해 흡착보다는 통과하는 성질이 크기 때문에 대부분의 기름성분들이 통과하게 된다. 또한 미세한 토사성분을 흡착한 기름성분들은 휘발성분이 날아가고 점성이 높아진 초코무스 형태로 여과재 표면에 점착하게 되어 유량통과를 가로막는 요인이 되며, 소나기성 강우 시 우수가 여과재를 통과하지 못하고 역류하여 정상적인 처리기능을 상실하는 문제가 있다.In particular, the filtration method using filter materials such as illite, zeolite, pit moss, etc. is mostly solid because of the solid nature of the filter media rate and the absorption capacity is reduced, so the oil component is largely passed through adsorption due to the treatment flow rate. The oil components of pass through. In addition, oil components adsorbing fine earth and sand components adsorb on the surface of the filter media in the form of volatile chocolate chips with high volatile content and high viscosity, which blocks the passage of the flow rate. There is a problem of losing.
또한 상기한 기존의 여과방식은 여과재 틈사이로 적체되는 오염물질이 거의 없고, 대부분 여과재 입구 표면에 걸리게 되며, 일정한 양에 이르게 되면 강우 시 유입되는 비점오염물질이 여과재의 표면을 막아 유입수의 역류현상이 발생하게 되며, 강우 전 후 여과재 표면을 세척 또는 교체해야 하는 문제가 대두되어 유지, 관리비용의 증가로 경제성이 떨어지는 문제가 있다.In addition, the conventional filtration method has almost no contaminants accumulated between the gaps of the filter medium, and most of them are caught on the inlet surface of the filter medium, and when a certain amount is reached, non-point contaminants introduced during the rainfall block the surface of the filter medium, thereby preventing the inflow of backwater. It occurs, and the problem of having to clean or replace the surface of the filter medium before and after the rainfall has risen, there is a problem of economic efficiency due to the increase in maintenance, management costs.
이에 본 발명자는 상기 종래의 문제점을 해결하기 위하여 부직포 섬유 원단 조각을 구부린 후, 끝부분을 말아서 중앙의 절개된 부분을 지나도록 하고, 원래의 방향으로 당겨 제조한 부직포 필터를 발명하였고, 이를 출원하여 공개된 바 있다(대한민국 공개특허공보 제10-2011-0006493호).In order to solve the above problems, the present inventors have invented a nonwoven fabric fabric by bending a piece of nonwoven fabric fabric, passing the cut portion at the center of the end portion, and pulling it in the original direction. It has been published (Korean Patent Publication No. 10-2011-0006493).
하지만 부직포 필터를 제작하는 단위공정 시간이 많이 소요되어 생산량이 떨어지는 단점이 있고, 고압의 에어(air)를 투입하여 필터 세척 시 에어(air)의 유동에 의해 풀어지는 사례가 발생하였다.
However, the production process of the non-woven fabric filter takes a lot of time, so there is a disadvantage in the amount of production, there is a case that is released by the flow of air (air) when cleaning the filter by applying a high-pressure air (air).
이에, 본 발명자들은 상기 종래기술들의 문제점들을 극복하기 위하여 예의 연구 노력한 결과, 부직포 섬유를 나비형상으로 가공하여 필터로 이용할 경우, 부피표면적 대비 중량이 작은 독립형상의 구조를 형성하도록 하여 필터 상호간에 엉키는 것을 방지하고, 초기우수 중의 토사성분과 같은 미세한 성분의 고형물이 필터에 부착되어 부피를 키우도록 함으로써 중력작용에 의해 침전시키며, 초기우수 중의 자동차 오일 및 연료와 같은 기름성분을 중량대비 20배 이상 흡수하고, 녹 성분과 같은 중금속물질을 흡착하며, 섬유에 항균제를 표면처리할 경우 곰팡이류 해조류 뿐만 아니라 박테리아를 사멸하고, 화학적인 수단 대신 물리적으로 박테리아를 사멸하기 때문에 환경에 위해를 가하지 않으며, 반복 사용하여도 제품의 성능이 저하되지 않고, 특히 선행 부직포 필터의 제조공정 문제점 및 필터 세척 시에도 필터의 손상을 방지할 수 있는 것을 확인하고 본 발명을 완성하게 되었다.
Accordingly, the present inventors have diligently researched to overcome the problems of the prior arts, and when the nonwoven fabric is processed into a butterfly shape and used as a filter, the present inventors form an independent structure having a small weight relative to the volume surface area, thereby tangling between the filters. It prevents, and solid matters of fine components such as earth and sand components in the initial rainwater are attached to the filter to increase the volume and settle by gravity action, and absorb oil components such as automobile oil and fuel in the initial rainwater by more than 20 times by weight. Adsorption of heavy metals such as rust, rust, and surface treatment of antimicrobial agents kills bacteria as well as fungi, algae, and physically kills bacteria instead of chemical means. The performance of the product is not degraded, Sure to prevent the manufacturing process problems and damage to the filter even when the filter cleaning non-woven fabric of the line filter, thereby completing the present invention.

도 1은 본 발명에 적용되는 부직포를 나타낸 도면이고, 도 2는 본 발명에 따른 부직포 섬유 필터를 나타낸 도면이며, 도 3 내지 도 4는 본 발명에 따른 부직포 섬유 필터의 가공방법을 나타낸 도면이다.1 is a view showing a nonwoven fabric applied to the present invention, Figure 2 is a view showing a nonwoven fabric filter according to the present invention, Figures 3 to 4 is a view showing a processing method of the nonwoven fabric filter according to the present invention.
도 1 내지 도 2에 도시된 바와 같이, 본 발명에 따른 부직포 섬유 필터는, 두께 3 ~ 5㎜를 갖는 부직포 섬유 원단을 재료로 하고, 상기 부직포 섬유 원단을 폭 25 ~ 40mm, 길이 50 ~ 70mm 로 자른 후 길이방향 중심에서 폭 방향으로 접어 나비형상으로 만든 후 중심부를 재봉틀로 박음질하여 인위적으로 나비형상의 모양으로 가공하여 제조할 수 있다.As shown in Figures 1 to 2, the nonwoven fabric filter according to the present invention, a nonwoven fabric fabric having a thickness of 3 to 5mm as a material, the nonwoven fabric fabric width 25 ~ 40mm, length 50 ~ 70mm After cutting, it is folded in the width direction from the center of the longitudinal direction to make a butterfly shape, and then the core is sewn with a sewing machine to be artificially processed into a butterfly shape.
이렇게 제조된 부직포필터는 부력과 수압에 의해 필터형상이 변형되지 않고 탄력적으로 변형 및 복원된다. 여과속도는 약 0.15m/sec로서 13.6배 이상의 여과속도를 나타내므로 1㎡ 당 9㎥/min를 처리할 수 있다. 또한, 부직포 섬유 원단의 두께가 4mm 일 경우, 유량통과능력이 100gal/min/ftㅂ이므로 여과속도는 약 0.068m/sec에 이르며, 1㎡ 당 4.079㎥/min의 유량처리능력을 보이고, 기존의 고정상 여재보다 약 6 ~ 7배 정도의 유량통과 능력을 보이고 있으나, 표 1에 기재한 바와 같이, 나비모양 형상으로 가공된 본 발명의 나비모양 형상의 필터에 비해 여과속도가 현저하게 떨어짐을 알 수 있다.The nonwoven filter thus manufactured is elastically deformed and restored without deforming the filter shape by buoyancy and water pressure. The filtration rate is about 0.15 m / sec, which represents a filtration speed of 13.6 times or more, so that 9 ㎥ / min can be treated per 1 m 2. In addition, when the thickness of the nonwoven fabric fabric is 4mm, the flow rate is 100 gal / min / ft ㅂ, so the filtration rate reaches about 0.068m / sec, showing a flow rate of 4.079㎥ / min per 1㎡. It shows about 6 to 7 times the flow-through capacity than the fixed bed media, but as shown in Table 1, it can be seen that the filtration rate is significantly lower than that of the butterfly-shaped filter of the present invention processed into a butterfly shape. have.
그리고 외국(미국)의 경우, 일반적으로 부직포 섬유 원단을 철망 사이에 펼쳐 부착한 후 처리수 관로에 장착하여 초기 처리수를 처리하고는 있으나, 잘 짜여진 부직포 섬유사 공극사이에 각종 부유물질들이 고착될 경우 심하게는 철망이 찢어지는 사례가 발생하기도 하며, 부직포 섬유 원단의 두께 3 ~ 5mm를 통과하는 처리수의 여과재 접촉 표면적이 상대적으로 작은 관계로 다량의 비점오염물질(Oil & Grease, 부유물질, 중금속, PAHs 등)을 연속적으로 제거하기가 어려우며, 결국 유지, 관리비용이 증가하게 된다.And in the case of foreign countries (USA), in general, the non-woven fabric is spread between the wire mesh and then attached to the treated water pipe to treat the initial treated water, but various suspended solids may be stuck between the well-woven nonwoven fabric yarn voids. In this case, the wire mesh may be severely torn, and since the contact surface area of the filter medium of the treated water passing through the thickness of the nonwoven fabric fabric is 3 to 5 mm is relatively small, a large amount of nonpoint pollutants (oil & grease, suspended solids, heavy metals) , PAHs, etc.) are difficult to remove continuously, resulting in increased maintenance and management costs.
또한, 도 3 내지 도 4에 도시된 바와 같이, 부직포 섬유 원단 길이방향의 중심을 나비모양이 되도록 재봉틀로 박음질하여 제조하기 때문에, 챔버(도시는 생략함)내에서 고압 에어(AIR)의 유동에도 풀리지 않고 형상을 보전할 수 있다.In addition, as shown in Figures 3 to 4, since the center of the longitudinal direction of the non-woven fabric fabric fabric is sewn with a sewing machine to produce a butterfly shape, the flow of high-pressure air (AIR) in the chamber (not shown) The shape can be preserved without loosening.
가공은 두께 3 ~ 5㎜의 부직포 섬유 원단을 폭 25 ~ 40mm, 길이 50 ~ 70mm가 되도록 자른 후 길이방향의 중심부를 접고 접힌 부위를 재봉틀로서 연속적으로 박음질한다.The process is to cut the non-woven fabric fabric of 3 ~ 5㎜ thick to 25 ~ 40mm in width, 50 ~ 70mm in length, and then fold the central portion in the longitudinal direction and sew the folded portion continuously as a sewing machine.
재봉틀에 의해 나비형상의 필터가 연속적으로 박음질된 부직포 섬유 원단조각을 각기 독립된 형상이 되도록 실밥을 절단하면 나비형상의 부직포 섬유 필터가 완성된다.The butterfly-shaped nonwoven fabric filter is completed by cutting the seams so that the butterfly-shaped filter is continuously sewn by the sewing machine.
챔버 내에 들어 있는 부직포 필터의 사용 상태를 살펴보면, 수심 1m 이하에 설치되는 나비형상의 부직포 섬유 필터가 충진된 W1000mm x L1000mm x H300mm의 표준 필터챔버가 받게 되는 부력은 10㎠ 당 0.3kg 이상인 바, 본 발명의 부직포 섬유 필터가 자연적으로 압착하는 효과를 나타내 처리수 속의 미세한 부유물질을 차단한다.When using the non-woven filter in the chamber, the buoyancy of W1000mm x L1000mm x H300mm filled with a butterfly-shaped nonwoven fiber filter installed at a depth of 1m or less is 0.3kg or more per 10cm2. The nonwoven fabric filter of the present invention exhibits a natural compression effect to block fine suspended matter in the treated water.
또한, 본 발명의 부직포 섬유 필터는, 처리수가 관통하여 흐를 수 있도록 타공판(도시는 생략함)으로 제작된 챔버(도시는 생략함) 내에 다수 채워 사용되고, 충진밀도는 외압이 없는 자연상태에서 필터통체 용적의 80% 범위로 하여 유입 유량과 유속에 따른 나비모양 형상 부유 필터의 유동성을 보장한다.In addition, the nonwoven fabric filter of the present invention is used in a plurality of chambers (not shown) made of a perforated plate (not shown) so that the treated water can flow therethrough, and the filling density is the filter cylinder in a natural state without external pressure. The range of 80% of the volume ensures the fluidity of the butterfly-shaped floating filter according to the inflow flow rate and flow rate.
상기와 같이 설정된 나비모양 형상 부유 필터의 충진밀도는 나비모양 형상 부유 필터가 상호 근접한 간격을 이루면서 형성되는 필터와 필터 사이에 공간을 형성하고, 이 공간은 처리수가 흐르는 유로가 된다.The filling density of the butterfly-shaped floating filter set as described above forms a space between the filter and the filter which are formed while the butterfly-shaped floating filter forms a close interval to each other, and this space is a flow path through which the treated water flows.
따라서 처리조(도시는 생략함)의 수로로 흐르는 기름성분 및 비점오염물질이 포함된 초기우수가 필터챔버를 통과하게 되면, 미세부유물들은 부유 필터 사이를 타고 이동하면서 합체되어 흡착 또는 침전하게 되고, Oil & Grease, 미세부유물질, 중금속, PAHs 등과 같은 비점오염물질은 부직포 섬유 필터에 흡착하게 되어 주기적으로 시행되는 유지, 관리 절차에 의해 청소 또는 교체되고, SS 성분의 고형물은 침전에 의해 필터챔버의 하부로 낙하하여 제거된다.Therefore, when the initial excellent water containing oil components and non-point pollutants flowing into the water treatment tank (not shown) passes through the filter chamber, the fine floats move between the floating filters, coalesce to adsorb or settle, Non-point contaminants such as oil & grease, fine suspended solids, heavy metals, PAHs, etc. are adsorbed on the nonwoven fabric filter and are cleaned or replaced by periodic maintenance and management procedures. Solids of SS components are removed from the filter chamber by precipitation. Dropped to the bottom and removed.
