Description

Purifying system without discharging of concentration water

본 고안은 정수기의 농축수 배출방법을 개선하여 낭비되는 농축수를 재사용할 수 있도록 한 정수기에 관한 것이다.The present invention relates to a water purifier that can reuse the wasted concentrated water by improving the method of discharging the concentrated water of the water purifier.

최근 물부족 현상이 전세계적인 차원의 문제점으로 부각되면서 날로 심각해지는 환경오염과 더불어 국민생활을 위협하는 문제가 되어 있고, 깨끗한 물에 대한 국민의 관심은 날로 높아져 정수기를 사용하는 가정이 해마다 늘어나 국내 가정용 정수기시장의 규모도 크게 증대되고 있는 실정이다.Recently, the lack of water has emerged as a global problem, and it is becoming a problem that threatens people's lives as well as environmental pollution, which is increasing day by day, and the public's interest in clean water is increasing day by day. The size of the water purifier market is also increasing significantly.

현재 가정용 정수기에 사용되는 정수시스템은 역삼투막 방식이 주류를 이루고 있는데, 입수된 물은 대개 전처리 여과필터 →전처리카본필터 →역삼투막필터(또는 한외여과막필터) →후처리카본필터를 거쳐 저장탱크로 유입된다. 이때 역삼투막 필터를 통과시 여과된 물은 후처리카본필터를 거쳐 저장탱크로 유입되는 한편, 막의 세척 등을 위해 사용된 후 폐기되는 농축수는 그대로 방출된다.Currently, the water purification system used in domestic water purifiers has a mainstream reverse osmosis membrane. The water obtained is usually introduced into the storage tank through the pretreatment filtration filter → pretreatment carbon filter → reverse osmosis membrane filter (or ultrafiltration membrane filter) → post treatment carbon filter. . At this time, the water filtered through the reverse osmosis membrane filter is introduced into the storage tank via the after-treatment carbon filter, while the concentrated water used for washing the membrane is discharged as it is.

그러나, 이러한 역삼투막 정수기는 농축수 방출로 인한 물낭비가 심한점이 단점으로 지적되면서 해마다 늘고 있는 정수기보급율에 비추어 볼때 향후 국가적인 차원의 물낭비로까지 심화될 소지가 있다.However, as the reverse osmosis membrane water purifier is pointed out as a serious waste of water due to the discharge of concentrated water, in the light of the increasing rate of water purifier supply every year, there is a possibility that the reverse osmosis membrane water purifier may be deepened to a national level of water waste in the future.

본 고안은 이러한 정수기의 농축수 방출을 해결하기 위한 것으로, 이를위해 정수시 발생되는 농축수의 배출방법을 개선하여 농축수 전량을 회수할 수 있도록 한 정수시스템을 제공하는 것을 그 목적으로 한 것이다.The present invention is to solve the discharge of the concentrated water of the water purifier, and to this end it is to provide a water purification system to recover the total amount of concentrated water by improving the discharge method of the concentrated water generated during the purification.

본 고안은 상기와 같은 고안의 목적을 달성하기 위한 일방법으로 종래 역삼투막 또는 한외여과막을 거쳐 배출되는 농축수를 농축수 급수배관을 통해 다시 수도수 밸브로 재급수하도록 한 새로운 정수시스템을 제공한다.The present invention provides a new water purification system for re-replenishing the concentrated water discharged through the conventional reverse osmosis membrane or ultrafiltration membrane back to the tap water valve through the concentrated water feed pipe as one method for achieving the object of the above-described design.

이하에서 첨부된 도면에 의거 본 고안을 구체적으로 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안에 따른 정수시스템은 도 1에 나타낸 바와 같이 수도수 급수밸브(2)가 개방되면 수도수배관(1)을 통해 수도수가 유입되어 전처리여과필터(5)를 통과한 후 가압펌프(4)에 의해 가압되어 전처리카본필터(6)를 통과한 후 역삼투막 필터 또는 한외여과막 필터를 거쳐 정수된다. 그리고 정수된 물은 후처리카본필터(8)를 거쳐 정수탱크(9)로 유입되고, 정수과정에서 농축된 농축수는 역류방지밸브(10)가 장착된 농축수급수배관 (11)을 통해 수도수급수밸브(2)로 다시 연결되어 배수된다. 이때 농축수 급수배관 (11)은 수도수를 취하지 않은 타수도수 배관에 연결될 수 있다.In the water purification system according to the present invention, as shown in FIG. 1, when the tap water supply valve 2 is opened, tap water is introduced through the tap water pipe 1 to pass through the pretreatment filtration filter 5, and then pressurized pump 4. It is pressurized by and passed through the pretreatment carbon filter 6, and it is purified through a reverse osmosis membrane filter or an ultrafiltration membrane filter. The purified water is introduced into the purified water tank (9) through the aftertreatment carbon filter (8), and the concentrated water concentrated in the water purification process is provided through the concentrated water supply pipe (11) equipped with a non-return valve (10). It is connected to the water supply valve 2 again and drained. At this time, the brine water supply pipe 11 may be connected to other tap water pipes do not take tap water.

그리고, 만수수위센서(12)에 의해 가압펌프(4)가 가동되면 수도수 급수밸브 (2)와 농축수 급수밸브(3)가 열리고 가압펌프(4)가 정지하면 수도수 급수밸브(2)와 농축수 급수밸브(3)가 닫히게 된다.When the pressurized pump 4 is operated by the full water level sensor 12, the tap water feed valve 2 and the concentrated water feed valve 3 are opened, and when the pressurized pump 4 is stopped, the tap water feed valve 2 is stopped. And the brine water supply valve (3) is closed.

한편, 이와 같은 정수시스템은 역삼투막을 이용한 정수기외에 한외여과막을 이용한 정수기에도 적용 가능하다.On the other hand, such a water purification system is applicable to a water purifier using an ultrafiltration membrane in addition to a water purifier using a reverse osmosis membrane.

이와 같이 구성된 본 고안에 따른 정수시스템을 사용하는 경우 농축수를 효율적으로 절약할 수 있어 가정용 정수기 보급에 따른 물낭비를 크게 줄일 수 있는 유용성을 지닌다.In the case of using the water purification system according to the present invention configured as described above, it is possible to efficiently save concentrated water, and thus has the usefulness of greatly reducing the waste of water due to the spread of household water purifiers.
