Description

복합형 광촉매 정화장치{Purifying apparatus}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

본 발명은 광촉매판과 이에 삽입된 램프가 정화하고자 하는 유체의 흐름 방향에 대하여 직각으로 배치된 부분(cross type)과, 나란하게 배치된 부분(vertical type)으로 구성된 복합형 구조를 가짐으로써, 각각의 장점을 가지고 각각의 단점을 보완함으로써 유체의 정화 효율을 극대화시킨 복합형 광촉매 정화장치에 관한 것이다.
The present invention has a composite structure comprising a photocatalytic plate and a lamp having a cross type arranged at right angles to a flow direction of a fluid to be purified and a vertical type arranged side by side, The present invention relates to a composite photocatalyst purification apparatus that maximizes the purification efficiency of a fluid by complementing the disadvantages of the photocatalyst purification apparatus.

일반적으로 광촉매 정화장치는 이산화티탄(Ti02)으로 된 전해질을 접촉시켜 음전하와 양전하가 가지는 정공으로 분리되는 광촉매에 광화학반응이 가능한 램프의 빛을 조사하여 발생되는 수산화라디칼을 통해서 오염된 기체나 액체를 정화하는 장치이다. 이와 같은 광촉매 정화장치는 광촉매가 코팅된 복수의 광촉매판과, 광촉매판에 광화학반응이 가능한 빛을 발생하는 램프로 구성된다.Generally, the photocatalytic purification apparatus is a system in which a photocatalytic reaction light is irradiated to a photocatalyst, which is separated into a positive hole and a positive hole, by contacting an electrolyte made of titanium dioxide (TiO 2), and a gas or a liquid It is a purifying device. The photocatalyst purification apparatus includes a plurality of photocatalyst coated photocatalyst plates, and a lamp for generating photochemical reaction light on the photocatalyst plate.

상기의 기본적인 구조에서 광촉매판과의 접촉을 증대시켜 정화 효율을 높이고자, 중앙을 따라 외측으로 나선형통로가 형성되도록 나선형을 길게 감긴 나선형 광촉매판을 적용시킨 튜브형 구조의 광촉매 정화장치까지 개발되어 있다.In order to enhance the cleaning efficiency by increasing the contact with the photocatalyst plate in the basic structure described above, a photocatalyst purification apparatus of a tubular structure has been developed in which a spiral photocatalyst plate is wound so that a spiral passage is formed along the center.

즉, 나선형 광촉매판은 그 외경에 맞는 튜브에 삽입되고, 나선형 광촉매판의 가운데 공간에는 램프가 삽입된다. 따라서 유체는 나선형에 의해 형성된 통로를 따라 회전되면서 지나가고, 그 동안의 광촉매판과의 접촉으로 정화되었다.That is, the helical photocatalytic plate is inserted into a tube corresponding to its outer diameter, and a lamp is inserted into the center space of the helical photocatalytic plate. The fluid thus passes through the passage formed by the spiral while being rotated, and has been purified by contact with the photocatalytic plate during this time.

그리고 나선형 광촉매판의 내측부에 주름부를 형성시켜 기체나 액체 등의 정화하고자 하는 유체와의 접촉면적을 확대하거나, 나선형 광촉매판의 전면에 복수의 통공을 천공함으로써 기체의 흐름을 원활하게 하여 정화 효과를 보다 형상시키기도 하였다.A wrinkle portion is formed on the inner side of the spiral photocatalyst plate to enlarge a contact area with a fluid to be cleaned such as a gas or a liquid or to puncture a plurality of holes on the entire surface of a spiral photocatalytic plate to smooth the flow of gas, .

그리고 광촉매 정화장치는 나선형 광촉매판이 유체의 흐름 방향에 대하여 수직으로 배치되거나, 흐름 방향과 나란하게 배치되었다. 즉, 공개특허번호 제10-2011-0050127호(2011.05.13)와 같은 나란한 배치의 구조가 개시되어 있다.
The photocatalytic purification apparatus is arranged such that the spiral photocatalytic plate is disposed perpendicular to the flow direction of the fluid or parallel to the flow direction. That is, the structure of a side-by-side arrangement such as that disclosed in Japanese Patent Laid-Open No. 10-2011-0050127 (May 23, 2011) is disclosed.

그러나 종래의 광촉매 정화장치는 나선형 광촉매판을 포함한 다양한 형태의 광촉매판이 유체의 흐름 방향에 대하여 수직 또는 평행되게 설치된 구조였다. 그 중 나란한 구조인 버티컬 타입(vertical type)은 유체가 광촉매판과의 접촉면적이 넓어 양호한 정화 능력은 있으나 흐름 저항이 높아서 흐름 유량이 적고 속력이 낮았다. 이러한 이유로 단시간에 많은 양의 유체를 정화할 수 없는 문제점이 있었다.However, the conventional photocatalytic purification apparatus has a structure in which various types of photocatalytic plates including spiral photocatalytic plates are vertically or parallelly arranged with respect to the flow direction of the fluid. Vertical type, which is a parallel type structure, has good cleaning ability because the area of contact between the fluid and the photocatalyst plate is large, but the flow resistance is low and the flow rate is low and the speed is low. For this reason, there has been a problem that a large amount of fluid can not be purified in a short time.

그리고 수직으로 배치된 크로스 타입(cross type)은 비교적 흐름은 좋으나 반응 효율이 상대적으로 낮은 문제점이 있었다.And the vertically arranged cross type has a relatively low flow rate but a relatively low reaction efficiency.

따라서 본 발명은 상기와 같은 종래의 문제점을 해소하는 구조를 가진 정화장치를 제공함에 목적이 있다.
SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art.

본 발명은 상기의 목적을 달성하기 위하여, 크로스 타입(cross type)과 버티컬 타입(vertical type)이 혼용되어 설치된 정화장치를 제공한다. 즉, 유체의 흐름 방향에 대하여 직각에 가깝게 설치된 나선형 광촉매판 또는 4각형 등의 판형 광촉매판과, 상기 각각의 광촉매판에 삽입된 램프와, 유체의 흐름 방향에 대하여 평행에 가깝게 설치된 광촉매판과 램프의 부분으로 구성된다.
In order to achieve the above object, the present invention provides a purifier in which a cross type and a vertical type are used in combination. That is, a plate-shaped photocatalytic plate, such as a spiral photocatalytic plate or a quadrangular plate, which is disposed at a right angle to the flow direction of the fluid, a lamp inserted into each of the photocatalytic plates, a photocatalytic plate provided in parallel to the flow direction of the fluid, .

본 발명에 따르면, 크로스 타입(cross type)과 버티컬 타입(vertical type)의 장점을 취하고, 서로의 단점을 보완함으로써 정화 효율이 극대화되는 효과가 있다. 즉, 크로스 타입의 흐름이 좋은 장점과 버티컬 타입의 반응 효율이 좋은 점을 동시에 가짐으로써 각각의 장점을 극대화함과 동시에 단점을 보완할 수 있게 된다.
According to the present invention, advantages of cross type and vertical type are taken, and the purification efficiency is maximized by complementing the weak points of each other. That is, by having the advantage of cross type flow and the advantage of reaction of vertical type at the same time, it is possible to maximize each advantage and to compensate for the disadvantages.

그리고 정화하고자 하는 유체가 유입되는 입구부인 케이스(2)의 상부에 가로 방향으로 광촉매판(4)이 먼저 설치되고, 그 하부에 세로 방향으로 광촉매판(4)이 설치됨에 특징이 있다.A photocatalytic plate 4 is installed in the upper part of the case 2, which is an inlet part through which the fluid to be purified flows, in the transverse direction, and a photocatalytic plate 4 is installed in the longitudinal direction below the photocatalytic plate 4.

그리고 상기의 광촉매판(4)은 나선형이거나, 삼각형 또는 사각형 등의 다각형이거나 원형 또는 타원형으로 구성된 판형일 수 있다. 따라서 나선형으로 길게 하나로 형성되는 나선형 광촉매판(4)이거나, 다수 개의 판형이 일정 간격으로 배치되어 형성된 판형 광촉매판(4)일 수 있다. 특히 본 발명의 최적 효과 달성을 위하여, 상부에 가로 방향으로 설치된 광촉매판(4)은 판형 광촉매판(4)이고, 그 하부에 세로 방향으로 설치된 광촉매판(4)은 나선형 광촉매판(4)임이 바림직하나 판형 광촉매판(4)이 설치될 수도 있다.The photocatalytic plate 4 may have a spiral shape, a polygonal shape such as a triangular shape or a square shape, or a plate shape having a circular shape or an elliptical shape. Therefore, the spiral photocatalytic plate 4 may be a spiral photocatalytic plate 4 formed in a long spiral shape or a plate-shaped photocatalytic plate 4 formed by arranging a plurality of plate types at regular intervals. Particularly, in order to achieve the optimum effect of the present invention, the photocatalytic plate 4 installed in the horizontal direction at the upper portion is a plate-shaped photocatalytic plate 4, and the photocatalytic plate 4 provided at the lower portion thereof in the longitudinal direction is a helical photocatalytic plate 4 A planar photocatalytic plate 4 may be provided.

그리고 가로 방향으로 설치된 광촉매판(4)은 유체의 흐름 방향에 대하여 완전한 직각인 90도로 가로질러 설치됨이 바람직하나, 45~90도의 범위도 가능하다. 물론 광촉매판(4)은 다수 개로써 층상구조로 배열될 수도 있고, 단층으로 배열될 수도 있다.It is preferable that the photocatalytic plate 4 installed in the transverse direction is installed across the 90 ° orthogonal to the flowing direction of the fluid, but it may be in the range of 45 to 90 degrees. Of course, the plurality of photocatalytic plates 4 may be arranged in a layered structure or may be arranged in a single layer.

그리고 상기의 램프(5)는 광촉매판(4)의 가운데에 하나가 설치될 수도 있고, 광촉매판(4)을 그 길이 방향으로 관통하여 여러 개가 설치될 수도 있다. 물론 램프(5)는 정화하고자 하는 유체의 특성과 오염 물질에 따라 자외선, 가시광선 등과 같이 여러 가지 광종의 램프(5)가 선택되어 사용된다. 즉, 오염의 종류나 분해 목적에 따라 오존 램프, UV-C 램프, UV-A 램프 기타 광촉매 반응이 가능한 램프 등 다양하게 선택되어 사용된다.One or more lamps 5 may be provided in the center of the photocatalytic plate 4, or a plurality of the photocatalytic plates 4 may be installed through the photocatalytic plate 4 in the longitudinal direction thereof. Of course, various lamps 5 such as ultraviolet rays, visible rays and the like are selected and used depending on the characteristics of the fluid to be purified and contaminants. That is, various kinds of ozone lamps, UV-C lamps, UV-A lamps, and other photocatalytic lamps can be selected depending on the type of contamination or decomposition purpose.

상기와 같은 본 발명의 작용과 효과를 첨부 도면을 참조하여 설명하면 다음과 같다.The operation and effect of the present invention will now be described with reference to the accompanying drawings.

정화하고자 하는 유체는 케이스(2)의 상부를 통해 유입된다. 상부에는 통기공(1)이 형성되어 있고, 케이스(2)의 하부에는 팬(6)이 설치되어 있다. 따라서 팬(6)의 작동에 의해 상부로 유체가 유입되는 구조이다.The fluid to be purified flows into the upper part of the case 2. A vent hole (1) is formed in the upper part, and a fan (6) is provided in the lower part of the case (2). Therefore, the fluid flows into the upper part by the operation of the fan 6. [

그리고 케이스(2)의 상부에는 전처리 장치(3)가 설치되어 있는데, 이는 큰 입자를 걸러주는 필터의 역할을 한다. 따라서 전처리 장치(3)는 부직포 필터, 집진기, 음이온 발생장치, 플라즈마 장치 등 먼지를 제거하는 어떠한 장치라도 가능하다.A pretreatment device 3 is provided on the upper part of the case 2, which serves as a filter for filtering large particles. Therefore, the pretreatment device 3 can be any device for removing dust such as a nonwoven fabric filter, a dust collector, an anion generating device, a plasma device and the like.

먼지가 걸러지면, 케이스(2)의 상부에 있는 크로스 타입, 즉 가로로 설치된 광촉매판(4)과 이에 삽입된 램프(5)에 의해 공기가 정화된다. 케이스(2)의 상부에 가로 방향으로 광촉매판(4)이 설치된 것이 본 발명의 특징 중에 하나인데, 이는 유입되는 초반에 유체의 흐름이 좋게 하기 위해서이다. 즉, 수직 방향으로 광촉매판(4)을 설치하게 되면, 광촉매판(4)에 의해 흐름 저항이 발생되어 유체의 유입에 방해가 된다. 따라서 초입 부분에 가로 방향으로 광촉매판(4)을 설치하여 유체의 유입을 용이하게 한다.When the dust is filtered, the air is cleaned by the cross-type photocatalytic plate 4 provided on the upper part of the case 2, that is, the horizontally installed photocatalytic plate 4 and the lamp 5 inserted therein. One feature of the present invention is that the photocatalytic plate 4 is provided on the upper side of the case 2 in the transverse direction in order to improve the flow of the fluid in the early stage of the flow. That is, when the photocatalytic plate 4 is installed in the vertical direction, flow resistance is generated by the photocatalytic plate 4, which interferes with the inflow of the fluid. Therefore, the photocatalytic plate 4 is provided in the transverse direction at the entrance portion to facilitate the inflow of the fluid.

특히, 유입부에 가로 방향으로 설치되는 광촉매판(4)은 흐름을 좋게 하기 위하여 나선형 광촉매판(4)보다는 판형 광촉매판(4)이 설치됨이 보다 바람직하다.Particularly, it is more preferable that the photocatalytic plate 4 installed in the transverse direction in the inflow portion is provided with a plate-shaped photocatalytic plate 4 rather than the helical photocatalytic plate 4 in order to improve flow.

상기의 가로 방향 설치 광촉매판(4)을 통해 유입된 유체는 하부에 있는 수직 방향으로 설치된 광촉매판(4)에 의해 유체가 체류되면서 정화 효율이 극대화된다. 물론 유체의 체류란 가로 방향으로 설치된 광촉매판(4)에서보다 흐름이 느리다는 의미이고, 수직 방향의 광촉매판(4)에 의해 흐름이 방해되는 것은 아니다.The fluid introduced through the transversely installed photocatalytic plate 4 is maximized in purification efficiency as the fluid is retained by the photocatalytic plate 4 installed vertically below the fluid. Of course, the retention of the fluid means that the flow is slower than in the photocatalytic plate 4 installed in the transverse direction, and the flow is not obstructed by the photocatalytic plate 4 in the vertical direction.

상기와 같이 본 발명은 가로형과 세로형의 광촉매판(4)을 층상으로 설치하고, 유입되는 유체는 가로형 광촉매판(4)에 의해 먼저 정화되면서 신속히 흘러 하부의 수직형 광촉매판(4)에 의해 다시 정화된다. 이 구간에서는 흐름이 지체되기 때문에 정화효율이 더욱더 높아지는 효과를 가지게 된다.
As described above, in the present invention, the horizontal and vertical photocatalytic plates 4 are provided in layers, and the inflow fluid is quickly purified while being purified by the lateral photocatalytic plate 4, It is purified again. In this section, since the flow is delayed, the purification efficiency is further increased.
