본 발명은 종래 원통형 구조의 ACF 필터의 문제점을 개선하고자 제시된 것으로서, 시트(Sheet) 타입의 원형 ACF(Activated Carbon Fiber) 필터 다수를 적층하여 형성하거나,The present invention has been proposed to improve the problem of the conventional cylindrical ACF filter, and is formed by stacking a plurality of sheet-type circular ACF (Activated Carbon Fiber) filters, or
또는 시트(Sheet) 타입의 원형 ACF(Activated Carbon Fiber) 필터와 필터 사이에 잔류염소제거층을 형성하여 디스크형을 이룸으로써, 통수량이 향상되고, 잔류염소 제거 기능이 뛰어난 ACF 디스크형 필터에 관한 것이다.Alternatively, a sheet-type circular ACF (Activated Carbon Fiber) filter and a disk-shaped filter are formed by forming a residual chlorine-removing layer between the filter. will be.
일반적인 샤워기는 수전으로부터 공급되는 물을 샤워헤드의 미세한 구멍을 통해 가는 물줄기로 공급하는 장치이다. A general shower is a device that supplies water supplied from a faucet to a thin stream of water through a fine hole in the shower head.
수돗물에는 병원균 또는 오염물질을 살균하기 위해 염소성분이 사용되며, 공급되는 수돗물에는 약 0.2~0.5 ppm의 염소성분이 함유되어 있다. 염소성분은 살균 등 위생을 목적으로 사용되고 있지만 수돗물 속의 잔류염소는 아토피성 피부염의 발병 원인으로 지적되기도 한다.In tap water, chlorine is used to sterilize pathogens or pollutants, and the supplied tap water contains about 0.2 to 0.5 ppm of chlorine. Chlorine is used for hygiene purposes such as sterilization, but residual chlorine in tap water is sometimes pointed out as the cause of atopic dermatitis.
또한 오래된 상수도관으로부터 녹 성분 등 오염물질이 공급되는 문제가 있다. In addition, there is a problem that contaminants such as rust are supplied from old water pipes.
이러한 문제의 해결을 위해 등록특허 10-1337749(등록일자: 2013년11월29일, 명칭: 정수 샤워기구)는 샤워기의 손잡이 또는 헤드부에 염소제거용 세라믹 볼을 충진한 다공성 정수필터가 구비되는 기술에 대해 개시하고 있으나, 정수필터의 교체가 어렵고 샤워시 수압이 약해지는 문제와 샤워기의 무게가 너무 무거운 단점이 있다.In order to solve this problem, Patent Registration 10-1337749 (Registration Date: November 29, 2013, Name: Water Purification Shower Device) is provided with a porous water filter filled with ceramic balls for removing chlorine in the handle or head of the shower. Although the technology has been disclosed, it is difficult to replace the water filter, the water pressure is weakened during the shower, and the weight of the shower head is too heavy.
ACF 필터 소재는 잔류염소, 유기물, 중금속 등 흡착기능을 활용하여 수돗물 정수용으로 널리 사용되고 있으며, 수돗물의 잔류염소 제거 목적으로 비타민 C, 아황산칼슘 등이 사용되고 있다.ACF filter material is widely used for purifying tap water by utilizing the adsorption function of residual chlorine, organic matter, heavy metal, etc., and vitamin C, calcium sulfite, etc. are used for the purpose of removing residual chlorine in tap water.
상기 비타민 C는 잔류염소 제거효율이 매우 우수하지만 화학반응에 의해 염화수소가 생성되는 문제가 있고 유지시간이 짧은 단점이 있다. 아황산칼슘의 경우 적은 양으로는 잔류염소 제거효율이 낮지만 온수에서도 효과가 유지되는 장점이 있다.Although the vitamin C has very excellent removal efficiency of residual chlorine, there is a problem in that hydrogen chloride is generated by a chemical reaction, and the retention time is short. In the case of calcium sulfite, the removal efficiency of residual chlorine is low with a small amount, but the effect is maintained even in hot water.
반면에 활성탄 ACF 필터는 미세기공의 물리적 흡착 기능으로 잔류염소를 제거하는 장점이 있지만 30 ℃ 이상의 온수에서는 제거 성능이 저하되는 단점이 있다.On the other hand, the activated carbon ACF filter has the advantage of removing residual chlorine through the physical adsorption function of micropores, but there is a disadvantage in that the removal performance is deteriorated in hot water above 30 ℃.
또한 ACF 필터는 잔류염소 제거 성능 유지시간이 길지만, 시간이 경과함에 따라 잔류염소 제거 성능이 점차적으로 현저하게 감소하는 경향을 보인다. In addition, the ACF filter has a long retention time for removing residual chlorine, but shows a tendency that the residual chlorine removal performance gradually and significantly decreases as time passes.
종래 ACF 필터는 대부분 도 1에 도시된 바와 같이, 원통형의 구조로 제작하여 손잡이에 장착하여 사용하고 있다.Conventional ACF filters, as shown in FIG. 1, are mostly manufactured in a cylindrical structure and mounted on a handle.
샤워헤드에 적용하는 경우에는 헤드용 필터의 두께가 50 cm 이상이 되어야 한다. 그러나 헤드의 두께가 얇은 샤워기에 맞춰 30 cm 이하 원통형 구조를 갖는 ACF 필터를 적용하면 통수량이 현저하게 감소되는 문제와 잔류염소 제거 성능을 발휘하는데 한계가 있다.When applied to a showerhead, the thickness of the filter for the head should be 50 cm or more. However, if an ACF filter having a cylindrical structure of 30 cm or less is applied to a shower with a thin head, there is a problem in that the amount of water passed is significantly reduced and there is a limitation in exhibiting the performance of removing residual chlorine.
본 발명은 종래 원통형 구조의 ACF 필터의 문제점을 개선하고자 제시된 것으로서, 시트(Sheet) 타입의 원형 ACF(Activated Carbon Fiber) 필터 다수를 적층하여 디스크형으로 형성하여 통수량이 많고 잔류염소 제거 기능이 뛰어난 ACF 디스크형 필터를 제공하고자 하는 것을 발명의 목적으로 한다.The present invention has been proposed to improve the problem of the conventional cylindrical ACF filter, and it is formed in a disk shape by stacking a plurality of sheet-type circular ACF (Activated Carbon Fiber) filters, which has a large amount of water passing and excellent ability to remove residual chlorine. It is an object of the invention to provide an ACF disk type filter.
상기 목적을 달성하기 위하여,To achieve the above object,
본 발명은 시트(Sheet) 타입의 원형 ACF 필터 다수를 적층하여 디스크형으로 형성된 것을 특징으로 하는 ACF 디스크형 필터를 제공한다.The present invention provides an ACF disk-type filter, characterized in that it is formed in a disk shape by stacking a plurality of sheet-type circular ACF filters.
또한,Also,
시트(Sheet) 타입의 원형 ACF 필터 다수를 디스크형으로 적층하되,A number of sheet-type circular ACF filters are stacked in a disk shape,
층과 층 사이에 아스코르빈산 및 그 유도체; 아황산칼슘 볼을 포함하는 잔류염소제거층이 형성되는 것을 특징으로 하는 ACF 디스크형 필터를 제공한다.Ascorbic acid and its derivatives between layers and layers; It provides an ACF disk-type filter, characterized in that the residual chlorine removal layer including calcium sulfite balls is formed.
본 발명에 따른 ACF 디스크형 필터는 다음의 효과를 갖는다.The ACF disk type filter according to the present invention has the following effects.
첫째, 물(water)이 통과하는 필터의 면적을 증가시켜 기존에 사용되던 원통형 필터가 갖고 있던, 수압이 높아지고 통수량이 적어지는 문제를 해결할 수 있다. First, by increasing the area of the filter through which water passes, it is possible to solve the problem of an increase in water pressure and a decrease in the amount of water passed, which the conventional cylindrical filter had.
둘째, ACF 필터와 잔류염소 제거 특성을 갖는 성분들과 복합화하여 ACF 하이브리드 필터를 구성함으로써, 잔류염소의 제거성능을 향상시키면서 사용수명을 장기간으로 유지할 수 있다는 장점을 갖는다.Second, by composing an ACF hybrid filter in combination with an ACF filter and components having residual chlorine removal characteristics, it has the advantage of improving the removal performance of residual chlorine and maintaining a long service life.
셋째, 잔류염소제거를 위해 사용하는 아스코르빈산의 용해속도를 본 발명에서 제시하는 코팅기술을 이용하여 조절할 수 있어 효과적으로 잔류염소제거가 가능하다는 장점을 갖는다.Third, since the dissolution rate of ascorbic acid used for removing residual chlorine can be controlled using the coating technology presented in the present invention, it has the advantage that residual chlorine can be effectively removed.

이하, 본 발명에 따른 ACF 디스크형 필터(1)에 대한 구체적인 기술 내용을 도면과 함께 살펴보도록 한다.Hereinafter, detailed descriptions of the ACF disk-
도 2 및 도 3에 도시된 바와 같이,2 and 3,
본 발명에 따른 ACF 디스크형 필터(1)는 시트(Sheet) 타입의 원형 ACF 필터(10) 다수를 적층하여 디스크형으로 형성된 것이다.The ACF disk-
기존의 원통형 필터의 경우, 도 1의 (a) 및 (b)에 도시된 바와 같이, 물(water)이 필터의 옆면을 통과하여 중앙 홀을 지나가야 하므로 필터의 높이가 낮을 경우에는 통과 면적이 너무 작아 필터에 걸리는 수압이 높아지고 통수량이 적어진다.In the case of a conventional cylindrical filter, as shown in (a) and (b) of Fig. 1, water must pass through the side of the filter and pass through the central hole, so when the height of the filter is low, the passage area is It is too small, so the water pressure applied to the filter is high and the water flow is reduced.
이와 같은 원통형 ACF 필터 구조를 적용할 수 없는 두께가 작은 샤워헤드의 경우 본 발명에서 제시하는 바와 같이, 시트(Sheet) 또는 펠트(Felt) 타입의 ACF 필터를 원형으로 가공하여 여러 층으로 겹쳐서 디스크형태의 카트리지를 만들면 물(water)의 통과면적을 증가시킬 수 있다.In the case of a showerhead having a small thickness to which such a cylindrical ACF filter structure cannot be applied, as suggested in the present invention, a sheet or felt type ACF filter is processed into a circular shape and overlapped with several layers to form a disk. If you make a cartridge of the water (water) can increase the passage area.
이와 같은 경우, 유효한 잔류염소 제거 능력을 발휘하도록 하기 위해서는 BET 값이 최소 1500 ㎡/g 이상으로 매우 큰 비표면적을 갖는 ACF 필터를 사용하여야 한다. 더욱 구체적으로는, BET 비표면적이 1500 ~ 2000 ㎡/g 인 것을 사용한다.In such a case, in order to exhibit effective residual chlorine removal ability, an ACF filter with a very large specific surface area with a BET value of at least 1500 ㎡/g should be used. More specifically, those having a BET specific surface area of 1500 to 2000
상기 시트(Sheet) 타입의 원형 ACF 필터(10)는 두께가 1.5~4.0 mm인 것을 사용하되, 여러 장을 적층하여 사용할 수 있다.The sheet-type
본 발명은 시트(Sheet) 타입의 원형 ACF 필터(10) 다수를 적층하여 디스크형의 필터(1) 구성에 더하여, 잔류염소 제거 특성을 갖는 다른 성분과 복합화하여 잔류염소 제거 성능을 보완하고 그 성능을 장기간 유지시킬 수 있다. In the present invention, in addition to the configuration of the disk-
더욱 구체적으로는, 도 4, 도 5 및 도 6에 도시된 바와 같이, 시트(Sheet) 타입의 원형 ACF 필터(10) 다수를 디스크형으로 적층하되,More specifically, as shown in FIGS. 4, 5 and 6, a plurality of sheet-type
층과 층 사이에 아스코르빈산 및 그 유도체; 아황산칼슘 볼을 포함하는 잔류염소제거층(20)이 형성하여 복합화함으로써 잔류염소 제거 성능을 보완하고 그 성능을 장기간 유지시킬 수 있다. Ascorbic acid and its derivatives between layers and layers; The residual
비타민 C로 알려진 아스코르빈산은 물에 대한 용해속도가 매우 빠르므로 용해속도를 제어하기 위해 표면을 코팅하여 적용한다. Ascorbic acid, known as vitamin C, has a very fast dissolution rate in water, so it is applied by coating the surface to control the dissolution rate.
코팅에 사용하는 물질은 하이드록시에틸셀룰로오스(HEC), 하이드록시메틸셀룰로오스(HMC), 하이드록시프로필메틸셀룰로오스(HPMC), 카르복시메틸셀룰로오스(CMC)의 셀룰로오스 류; 콜라겐; 알긴산 나트륨; 한천; 우뭇가사리; 카라기난; 잔탄검; 아라비아검; 중 선택되는 어느 1종 또는 2종 이상을 사용할 수 있다. 이와 같은 코팅물질로 코팅함으로써 물에 대한 용해도속도를 낮출 수 있다.Materials used for coating include celluloses such as hydroxyethylcellulose (HEC), hydroxymethylcellulose (HMC), hydroxypropylmethylcellulose (HPMC), and carboxymethylcellulose (CMC); Collagen; Sodium alginate; Agar; Dark agar; Carrageenan; Xanthan gum; Arabian sword; Any one or two or more selected from among can be used. By coating with such a coating material, the solubility rate in water can be lowered.
상기 코팅은 아스코르빈산 및 그 유도체 분말에 코팅물질을 첨가하여 균질하게 혼합한 후 압축성형기 또는 과립기로 성형하여 코팅하되, 아스코르빈산 및 그 유도체 분말 70.0 ~ 90.0 wt%와 코팅물질 10.0 ~ 30.0 wt%의 배합비를 이룬다.The coating is coated by adding a coating material to ascorbic acid and its derivative powder, homogeneously mixing it, and then molding it with a compression molding machine or a granulator, and coating it with 70.0 to 90.0 wt% of ascorbic acid and its derivative powder and 10.0 to 30.0 wt. % Blending ratio.
더욱 구체적으로는, 0.5 mm 이하의 아스코르빈산 및 그 유도체 분말 80.0 wt%에 상기 코팅물질 20.0 wt%를 첨가하여 균질하게 혼합하고 압축성형기 또는 과립기로 성형하여 코팅된 비타민 C를 제조한다. More specifically, 20.0 wt% of the coating material is added to 80.0 wt% of 0.5 mm or less of ascorbic acid and its derivatives powder, homogeneously mixed, and molded with a compression molding machine or a granulator to prepare coated vitamin C.
아황산칼슘은 수돗물의 잔류염소 제거 목적으로 사용하는 것으로서, 볼 형태로 사용한다.Calcium sulfite is used for the purpose of removing residual chlorine in tap water, and is used in the form of a ball.
상기 ACF 필터와 복합화하여 잔류염소 제거 성능을 증가시키기 위해 0.2~3.0 mm 크기의 아황산칼슘 볼을 사용하여 비표면적을 최대한 높여 사용한다. 바람직하게는 0.5~2.0 mm의 크기로 작게 만들어 사용한다.In order to increase the residual chlorine removal performance by combining with the ACF filter, a 0.2-3.0 mm-sized calcium sulfite ball is used to maximize the specific surface area. Preferably, it is used by making it small in a size of 0.5 to 2.0 mm.
상기 볼의 직경이 0.2 mm 보다 작은 경우 너무 빨리 용해되어 소진되거나 ACF 필터를 빠져나갈 우려가 있고, 3.0 mm 보다 큰 경우에는 차지하는 공간이 너무 크고 용해속도가 너무 느려서 잔류염소제거 효율이 떨어지는 단점이 있으므로, 상기 볼의 크기는 0.2~3.0 mm의 범위 내로 유지하는 것이 바람직하다.If the diameter of the ball is less than 0.2 mm, it will dissolve too quickly and may be exhausted or escape the ACF filter.If it is larger than 3.0 mm, the space occupied too large and the dissolution rate is too slow, so the efficiency of removing residual chlorine decreases. , It is preferable to maintain the size of the ball within the range of 0.2 to 3.0 mm.
이하, 본 발명에 따른 ACF 디스크형 필터(1)를 도 7의 (c)에 도시된 바와 같이 샤워헤드에 장착하여 잔류염소를 측정하였다. 이에 대한 구체적인 내용을 실시예를 통해 살펴보도록 한다.Hereinafter, the ACF disk-
BET 비표면적 1800 ㎡/g, 두께 2 mm인 ACF 필터를 직경 60 mm의 원형으로 가공한 후 8장을 적층하여 케이스에 조립하고 샤워헤드에 장착하여 잔류염소를 측정하였다.After processing an ACF filter with a BET specific surface area of 1800 ㎡/g and a thickness of 2 mm into a circular shape with a diameter of 60 mm, 8 sheets were stacked, assembled on a case, and mounted on a shower head to measure residual chlorine.
유속을 5.5 L/분으로 하여 2 시간 통수 후 잔류염소 측정 결과 0.08 mg/L로 원수의 잔류염소가 80 % 이상 제거된 것을 확인할 수 있다.After passing water for 2 hours with a flow rate of 5.5 L/min, the result of measuring residual chlorine was 0.08 mg/L, indicating that more than 80% of residual chlorine in raw water was removed.
BET 비표면적 1800 ㎡/g, 두께 4 mm인 ACF 필터를 직경 60 mm의 원형으로 가공한 후 4장을 적층하여 케이스에 조립하고 샤워헤드에 장착하여 잔류염소를 측정하였다.After processing an ACF filter with a BET specific surface area of 1800 ㎡/g and a thickness of 4 mm into a circular shape with a diameter of 60 mm, 4 sheets were stacked, assembled on a case, and mounted on a shower head to measure residual chlorine.
유속을 5.5 L/분으로 하여 2 시간 통수 후 잔류염소 측정 결과 0.09 mg/L로 원수의 잔류염소가 78 % 이상 제거된 것을 확인할 수 있다.After passing water for 2 hours at a flow rate of 5.5 L/min, the result of measuring residual chlorine was 0.09 mg/L, indicating that more than 78% of the residual chlorine in raw water was removed.
BET 비표면적 1500 ㎡/g, 두께 2 mm인 ACF 필터를 직경 60 mm의 원형으로 가공한 후 8장을 적층하여 케이스에 조립하고 샤워헤드에 장착하여 잔류염소를 측정하였다.After processing an ACF filter with a BET specific surface area of 1500
유속을 5.5 L/분으로 하여 2 시간 통수 후 잔류염소 측정 결과 0.25 mg/L로 잔류염소가 39 % 정도밖에 제거되지 않은 것을 확인할 수 있다.After passing water for 2 hours at a flow rate of 5.5 L/min, the result of measuring residual chlorine was 0.25 mg/L, indicating that only about 39% of residual chlorine was removed.
BET 비표면적 1800 ㎡/g, 두께 4 mm인 ACF 필터를 직경 60 mm의 원형으로 가공한 후 4장을 적층하여 각 층의 사이에 직경이 1.0 mm인 아황산칼슘 볼을 2 g씩 총 6 g을 추가하여 구성한 ACF 디스크형 필터를 케이스에 조립하고 샤워헤드에 장착하여 잔류염소를 측정하였다.After processing an ACF filter with a BET specific surface area of 1800 ㎡/g and a thickness of 4 mm into a circular shape with a diameter of 60 mm, 4 sheets were stacked to add 2 g of calcium sulfite balls with a diameter of 1.0 mm between each layer. The additionally constructed ACF disk-type filter was assembled to the case and mounted on the showerhead to measure residual chlorine.
유속을 5.5 L/분으로 하여 5시간 통수 후 잔류염소가 0.12 mg/L로 측정되어 실시예 2에 비해 잔류염소 제거 성능이 향상된 것을 확인할 수 있었다.After passing water for 5 hours at a flow rate of 5.5 L/min, residual chlorine was measured to be 0.12 mg/L, and it was confirmed that the residual chlorine removal performance was improved compared to Example 2.
또한 ACF 필터를 여러 층으로 겹쳐서 만들수록 통수량이 감소되는 문제가 있으므로 이러한 문제를 해결하기 위해 ACF 필터의 각 층의 사이에 볼을 넣어 구성함으로써 통수량의 감소량이 30%(5.5 L/분 → 3.8 L/분)에서 10% 이하((5.5 L/분 → 5.0 L/분)로 개선되었다. In addition, there is a problem that the water flow rate decreases as the ACF filter is made by layering multiple layers. To solve this problem, the amount of water flow is reduced by 30% (5.5 L/min → It improved from 3.8 L/min) to 10% or less ((5.5 L/min → 5.0 L/min).
BET 비표면적 1800 ㎡/g, 두께 4 mm인 ACF 필터를 직경 60 mm의 원형으로 가공한 후 4장을 적층하고 각 층의 사이에 HPMC 2208로 표면처리한 비타민 C를 1.5g씩 추가하여 구성한 ACF 디스크형 필터를 케이스에 조립하고 샤워헤드에 장착하여 잔류염소를 측정하였다.ACF consisting of an ACF filter with a BET specific surface area of 1800 ㎡/g and a thickness of 4 mm, processed into a circle with a diameter of 60 mm, stacked 4 sheets, and added 1.5 g of vitamin C surface-treated with HPMC 2208 between each layer. The disk-shaped filter was assembled to the case and mounted on the showerhead to measure residual chlorine.
유속을 5.5 L/분으로 하여 5시간 통수 후 잔류염소가 0.10 mg/L로 측정되어 실시예 2에 비해 잔류염소 제거 성능이 향상된 것을 확인할 수 있었다.After passing water for 5 hours at a flow rate of 5.5 L/min, residual chlorine was measured to be 0.10 mg/L, and it was confirmed that the residual chlorine removal performance was improved compared to Example 2.
상기 제시한 실시예 1 내지 5의 실험 결과를 종합하면 아래 표 1과 같다.When the experimental results of Examples 1 to 5 presented above are summarized, they are shown in Table 1 below.
비표면적이 큰(BET = 1800㎡/g) ACF 필터의 경우 잔류염소가 유효하게 제거됨을 알 수 있고, 비타민 C 또는 아황산칼슘 볼을 첨가하여 하이브리드화함으로써 잔류염소가 제거되는 시간이 연장될 수 있음을 확인할 수 있다.In the case of an ACF filter with a large specific surface area (BET = 1800㎡/g), it can be seen that residual chlorine is effectively removed, and the time to remove residual chlorine can be extended by hybridizing with the addition of vitamin C or calcium sulfite balls. can confirm.
[ 시험예 ][Test Example]
상기 실시예 2와 실시예 4와 동일하게 구성한 필터를 실사용 조건으로 사용하면서 잔류염소량을 측정하여 그 변화를 비교하였다. Filters constructed in the same manner as in Example 2 and Example 4 were used under actual use conditions, and the amount of residual chlorine was measured and the changes were compared.
유속을 5.5 L/분으로 하여 10분 통수 후 잔류염소를 측정하고 150분 중단 후 10분 통수하고 측정하는 방법으로 반복하여 그 결과를 평가하였다.The result was evaluated by repeating the method of measuring residual chlorine after passing water for 10 minutes at a flow rate of 5.5 L/min, and passing water for 10 minutes after stopping for 150 minutes.
잔류염소를 측정한 실험 결과를 나타낸 도 8의 그래프를 통해 확인되는 바와 같이, 아황산칼슘 볼을 첨가한 ACF 디스크형 필터가 첨가하지 않은 ACF 디스크형 필터에 비해 약 2배의 염소제거 효과를 나타낸다는 것을 알 수 있었다. As can be seen from the graph of FIG. 8 showing the experimental results of measuring residual chlorine, the ACF disk-type filter with calcium sulfite balls added shows about twice the chlorine removal effect compared to the ACF disk-type filter without the addition of calcium sulfite balls. I could see that.
“ACF”는 ACF 필터 단독으로 구성된 실시예 2이고,“ACF+CS”는 아황산칼슘 볼을 첨가한 실시예 4를 나타낸다.“ACF” refers to Example 2 consisting of an ACF filter alone, and “ACF+CS” refers to Example 4 to which calcium sulfite balls are added.
본 발명에 따른 ACF 디스크형 필터는 기존 원통형 필터에 걸리는 수압이 높고 통수량이 작아지는 문제를 해결하여 물(water)의 통과면적을 증가시킬 수 있고, ACF 필터와 잔류염소 제거 특성을 갖는 성분들과의 복합화를 통해 잔류 제거성능을 향상시키면서 사용수명을 장기간으로 유지할 수 있다는 장점을 가짐으로써 산업상 이용가능성이 크다.The ACF disk filter according to the present invention solves the problem that the water pressure applied to the existing cylindrical filter is high and the amount of water passing through it is small, so that the water passage area can be increased, and the ACF filter and components having the characteristics of removing residual chlorine It has the advantage of being able to maintain the service life for a long time while improving the residual removal performance through the combination with the product, and thus it has great industrial applicability.
