이러한 종래의 기술로서 등록실용신안등록번호 실013788호 "정수기"가 기재되어 있다. 도 1은 상기 등록실용신안의 일반적인 정수기의 구성을 도시한 개략도로서 수도꼭지(10)에 연결된 연결호스(11)를 통해 나온 원수는 굵은 찌거기나 부유물질을 걸러주는 세디멘트필터(12)를 통과하는 한편, 그 후 프리카본필터(13)로 유입을 제거하는 콘트롤장치(18)에 의해 작동하는 차단밸브(17)를 거치게 되고, 상기 차단밸브(17)를 통해 나온 물은 물 속의 염소성분을 제거하여 주는 프리카본필터(13)를 거치게 되며, 펌프(19)에 의해 강제적으로 압송된 물은 멤브레인필터(15)에서 기존의 0.0001㎛의 미세한 구멍을 통하여 일반세균 및 각종 불순물을 걸러내는 한편 냄새나 유해한 가스성분 등을 완전히 제거하여 주는 포스트카본필터(16)를 거쳐 정수탱크(20)에 저장된 물이 일정 상한 수위까지 차 오르게 되면 이를 감지하는 리미트스위치(21)가 차단밸브(17)로써 물의 유입을 막도록 콘트롤장치(18)에 신호를 인가하도록 구성되어 있다.As such a conventional technology, the registration utility model registration number No. 013788 "water purifier" is described. Figure 1 is a schematic diagram showing the configuration of a general water purifier of the utility model, the raw water coming out through the connection hose 11 connected to the faucet 10 is passed through the sediment filter 12 for filtering coarse residue or suspended matter On the other hand, thereafter through the shut-off valve 17 which is operated by the control device 18 to remove the inflow to the pre-carbon filter 13, the water coming out through the shut-off valve 17 to remove the chlorine component in the water After passing through the pre-carbon filter 13, the water forcibly pushed by the pump 19 filters the general bacteria and various impurities through the existing micro holes of 0.0001 ㎛ in the membrane filter 15, When the water stored in the purified water tank 20 rises to a certain upper limit level through a post carbon filter 16 which completely removes harmful gas components, the limit switch 21 for detecting this is used as a shutoff valve 17. It is configured to apply a signal to the control device 18 to prevent the inflow of water.

통상 역삼투압 정수기의 멤브레인필터(15)를 통과하는 정수량과 멤브레인필터(15)를 통과하지 못하여 폐수로 분류되는 폐수량은 약 1:3의 비율로 정수가 이루어지므로 이러한 일차 정수된 폐수가 아무런 소용없이 버려지는 실정이다.Usually, the amount of purified water that passes through the membrane filter 15 of the reverse osmosis water purifier and the wastewater that is not passed through the membrane filter 15 are classified into wastewater at a ratio of about 1: 3, so that the primary purified wastewater is of no use. Abandoned.

한편, UN의 워싱톤 소재 국제 인구행동연구소(PAI)의 발표에 따르면 한국의활용 가능한 물 자원량은 661억 톤으로서 이를 국민 1인당 활용 가능량으로 환산할 경우, 한국은 1950년 3,247톤에서 1995년에는 1,472톤으로 줄어들어 물 부족 국가로 분류되고 있는 현실이다.Meanwhile, according to the UN's Washington-based Institute of International Population and Behavioral Research (PAI), Korea's available water resource is 66.1 billion tons, which translates into 3,247 tons per capita in 1950 and 1,472 in 1995. It is reduced to tons and is classified as a water shortage country.

현재 사용되고 있는 역삼투압 정수기는 RO 멤브레인 필터의 막힘에 의한 정수수 수질 향상 및 정수량 감소를 막기 위해 일정량의 폐수를 배출하고 있다. 이 폐수의 양이 정수량의 3배 이상이 되므로 정수량 1리터를 얻기 위해 폐수량 3리터를 버리는 문제점이 있어 왔다.Reverse osmosis water purifiers are currently being used to discharge a certain amount of wastewater in order to prevent the improvement of purified water quality and decrease the amount of purified water by clogging the RO membrane filter. Since the amount of this wastewater is three times or more of the amount of purified water, there has been a problem of discarding the amount of wastewater 3 liters to obtain 1 liter of purified water.

통상적으로 역삼투압 방식의 정수기는 삼투압현상 즉 농도가 묽은 쪽의 액체가 삼투막을 통하여 농도가 진한 쪽으로 이동되는 자연현상으로부터 착안하여 상기 농도가 진한 쪽에 인위적인 압력을 가하여 고농도의 용액 속의 용매인 물이 삼투막을 통과하여 저농도쪽으로 이동토록 하는 인위적인 작용을 이용하여 정수를 이루는 것으로서, 제2도에는 역삼투압 방식의 정수기가 도시되어 있는데, 이는 수도전(1)으로부터 원수를 공급받아 5미크론 정도의 미세한 필터를 통해 먼지, 찌꺼기, 각종 부유 물질이 제거되는 세디먼트필터(12)와, 활성판의 흡착방식을 이용하여 발암물질(THM), 합성세제, 살충제등 인체에 유해한 화학물질과 염소 성분둥을 제거하는 프리카본필터(13), 0.0001미크론의 역삼투막으로 이루어져 납, 비소와 같은 중금속은 물론 나트륨, 박테리아 바이어스, 방사성 물질등을 걸러주며 일부는 드레인관(32)을 통해 수도전(1)측으로 회류시키는 멤브레인 필터(15), 불쾌한 맛과 냄새, 색소 등을 제거하는 포스트카본필터(16)로 이루어지며 상기세디먼트필터(12)와 프리카본필터(13)사이의 유로에는 솔레노이드밸브(14) 및 펌프(19)가 설치되어 소정의 압력을 가하며 원수를 공급할 수 있도록 되어 있고, 미설명부호 42는 미네랄투입수단이고, 44는 살균수단이다.In general, the reverse osmosis type water purifier focuses on the osmotic phenomenon, ie, a natural phenomenon in which a liquid having a thinner concentration moves to a higher concentration through an osmotic membrane. In order to achieve the purified water by using an artificial action to move through the membrane toward the lower concentration, a reverse osmosis water purifier is shown in FIG. 2, which receives raw water from the tap water (1) and filters the microfilter about 5 microns. The sediment filter 12 removes dust, debris and various suspended substances through the adsorption method of the active plate, and removes harmful substances such as carcinogens (THM), synthetic detergents, insecticides, and chlorine components. Free carbon filter (13), consisting of 0.0001 micron reverse osmosis membrane, heavy metals such as lead, arsenic, sodium, foil Filters the lia bias, radioactive material and the like, and part of the membrane filter 15 to flow back to the water field 1 through the drain pipe 32, and the post carbon filter 16 to remove unpleasant taste and smell, pigments, etc. The solenoid valve 14 and the pump 19 are installed in the flow path between the sediment filter 12 and the free carbon filter 13 to supply the raw water while applying a predetermined pressure. Mineral input means, 44 is a sterilization means.

그러나 이와 같은 방식은 상기 정수 단계 중 가장 미세한 구멍을 갖는 멤브레인필터(15)의 청소기능이 구비되어 있지 않아 멤브레인필터(15)에 필터링된 물질(박테리아, 바이러스, 방사성물질, 납, 비소 등)이 누적되어 정수효율이 떨어질 뿐만 아니라 특히 위생상태를 저하시킬 우려를 갖고 있었다. 또한 경도성 물질을 다량 함유하고 있는 물을 정수하는데 있어 멤브레인필터(15)의 작동능력에 한계가 있고 경도성 물질이 멤브레인필터(15)의 막에 스케일을 발생시켜 조기 막힘을 유발한다. 그리고 이러한 경도가 높은 물은 정수기의 수명과 부품의 수명을 단축시키는 문제점이 있어 왔다.However, this method is not equipped with a cleaning function of the membrane filter 15 having the finest hole in the water purification step, so that the filtered material (bacteria, viruses, radioactive materials, lead, arsenic, etc.) in the membrane filter 15 Accumulated to reduce the efficiency of water purification, in particular, there was a fear of lowering the hygiene. In addition, there is a limit to the operation ability of the membrane filter 15 in purifying water containing a large amount of the hardness material, and the hardness material generates scale on the membrane of the membrane filter 15 to cause premature clogging. And such high hardness water has a problem of shortening the life of the water purifier and the life of the parts.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로,The present invention has been made to solve the above problems,

본 발명의 제1목적은 멤브레인필터에서 버려지는 생활용수를 재사용하는 폐수절감형 정수시스템을 제공하는 것이고,It is a first object of the present invention to provide a wastewater reduction type purification system for reusing living water discarded in a membrane filter.

본 발명의 제2목적은 멤브레인필터의 조기막힘을 방지하고 안정적인 수질의 정수수를 공급할 수 있는 시스템을 제공하는데 있다.It is a second object of the present invention to provide a system capable of preventing premature clogging of a membrane filter and supplying purified water of stable water quality.

원수(100)가 세디멘트필터(110)를 통과하면서 원수 속에 포함된 큰 입자의 부유물질 및 녹 찌거기를 제거하고, 상기 세디멘트필터(110)를 통과한 원수는 부스터펌프(120)를 통해 가압된 후 자동압력조절장치(140)를 통과하면서 멤브레인필터(150)에 공급된다. 상기 자동압력조절장치(140)는 원수유입구(142)를 통과한 수압에 의해 시트(141a)에서 볼이(145a) 떨어지고, 원수유출구(144)를 통해 배출되는 원수를 프리카본필터(130)를 통과시키고, 상기 프리카본필터(130)를 통과한 원수를 압력 손실없이 멤브레인필터(150)에 공급한다. 정수작용이 끝나면 개방되었던 스프링 밸브(145)가 스프링(145c)의 탄성력에 의해 볼(145a)이 시트(141a)를 막게 되고, 대기압유입구(143)를 통과하여 외부공기가 유입되어 원수유출구(144)로 원수가 흐르지 못하므로 상기 멤브레인필터(150) 내부에는 수압이 걸리지 않아 멤브레인필터(150) 내부에 잔존해 있던 고농축 생활용수를 배출시켜 멤브레인필터(150)의 조기 막힘을 방지한다.As the raw water 100 passes through the sediment filter 110, the floating particles and rust residues of the large particles contained in the raw water are removed, and the raw water passing through the sediment filter 110 is pressurized through the booster pump 120. After passing through the automatic pressure control device 140 is supplied to the membrane filter 150. The automatic pressure control device 140 is a ball 145a from the seat 141a by the water pressure passed through the raw water inlet 142, the raw water discharged through the raw water outlet 144 to the pre-carbon filter 130 The raw water passed through the precarbon filter 130 is supplied to the membrane filter 150 without pressure loss. When the water purification operation is completed, the spring valve 145, which was opened, blocks the seat 141a by the elastic force of the spring 145c, and the outside air flows through the atmospheric pressure inlet 143 to feed the raw water outlet 144. Since the raw water does not flow into the membrane filter 150, the water pressure is not applied to the membrane filter 150, thereby discharging the highly concentrated living water remaining in the membrane filter 150 to prevent premature clogging of the membrane filter 150.

상기 멤브레인필터(150)는 기존의 0.0001㎛의 미세한 구멍을 통하여 일반세균 및 각종 불순물을 걸러내는 한편 원수에 포함된 각종 중금속이나 발암물질, 박테리아 등의 세균을 제거하여 정수된 물들을 포스트카본필터(160)에 공급하도록 연결되어 있다.The membrane filter 150 filters the general bacteria and various impurities through the existing micropore of 0.0001 μm, and removes various heavy metals, carcinogens, bacteria, etc. contained in the raw water and removes purified water from the post carbon filter ( 160 to supply.

상기 포스트카본필터(160)는 정수된 물의 냄새를 제거하고 미생물의 번식을 차단하여 자동압력조절장치(170)를 통과한다. 상기 자동압력조절장치(170)는 정수된 물을 상기 정수탱크(180)에 공급하고, 상기 정수탱크(180)로부터 정수물의 역류를 차단하며 정수시스템의 운전 정지시 외부공기 유입으로 포스트카본필터(160)에 잔존해 있던 정수된 물을 상기 멤브레인필터(150)로 역류시킨다. 이 경우 삼투압현상으로 인해 멤브레인필터(150) 표면으로 정수된 물을 방출하여 멤브레인필터(150) 표면에 쌓인 멤브레인필터(150) 막힘현상을 일으키는 물질들을 멤브레인필터(150) 표면과 분리시킨다. 상기 멤브레인필터(150)를 통과하지 못한 폐수들은 폐수토출관(152)을 통해 분지관(153)에서 일부는 폐수공급관(122)을 통과하여 부스터펌프(120)에 공급되어 프리카본필터(130) 및 멤브레인필터(150)를 거쳐 필터링되고, 일부는 드레인관(191)과 연통되어 있는 폐수조절솔밸브(190)를 통해 배출된다.The post carbon filter 160 removes the smell of purified water and blocks the growth of microorganisms and passes through the automatic pressure regulating device 170. The automatic pressure regulating device 170 supplies purified water to the purified water tank 180, blocks the reverse flow of purified water from the purified water tank 180, and post-carbon filters into the inflow of external air when the purified water system is stopped. The purified water remaining in 160 is returned to the membrane filter 150. In this case, the purified water is discharged to the surface of the membrane filter 150 due to the osmotic pressure to separate substances causing the clogging of the membrane filter 150 accumulated on the surface of the membrane filter 150 from the surface of the membrane filter 150. Wastewater that has not passed through the membrane filter 150 is partially supplied from the basin pipe 153 through the wastewater supply pipe 122 through the wastewater discharge pipe 152 and supplied to the booster pump 120 to supply the free carbon filter 130. And is filtered through the membrane filter 150, a part is discharged through the waste water control brush valve 190 in communication with the drain pipe 191.

폐수절감형 정수시스템에서 정수가 멈추면 폐수조절솔밸브(190)가 열리게 되고, 자동압력조절장치(140)에 의해 상기 멤브레인필터(150)에 남아 있던 농축폐수가 배출된다. 또한 자동압력조절장치(170)에 의해 포스트카본필터(160)에 남아있던 정수된 물이 멤브레인필터(150)로 공급된다. 이 경우 삼투압현상으로 인해 정수된 물이 상기 멤브레인필터(150) 표면으로 흘러 상기 멤브레인필터(150) 표면의 이물질들을 분리시킨 후, 정수 시작 전 10초 동안 순간 후레싱으로 이물질들을 배출하여 멤브레인필터(150)를 세척한다.When the purified water stops in the wastewater reduction type purification system, the wastewater control brush valve 190 is opened, and the concentrated wastewater remaining in the membrane filter 150 is discharged by the automatic pressure regulating device 140. In addition, purified water remaining in the post carbon filter 160 is supplied to the membrane filter 150 by the automatic pressure regulating device 170. In this case, water purified by osmotic pressure flows to the surface of the membrane filter 150 to separate foreign substances on the surface of the membrane filter 150, and then discharges foreign substances by flash flashing for 10 seconds before the start of water purification. )).
