도 1은 본 발명에 따른 반응기의 사시도로서, 도면에 도시된 바와 같이, 본 발명에 따른 반응기(10)는 외관을 이루는 전해조(11)와, 이 전해조(11)의 내부에 복수 구비되는 전극판(12)으로 이루어진 구조이다. 1 is a perspective view of a reactor according to the present invention, as shown in the drawing, the reactor 10 according to the present invention is an electrolytic cell 11 forming an appearance, and a plurality of electrode plates provided inside the electrolytic cell 11 It consists of (12).

상기 전해조(11)의 전후방으로는 수처리를 위한 유입구(11a)와 유출구(11b)가 형성된다. Inlet and outlet 11a and outlet 11b for water treatment are formed in front and rear of the electrolytic cell 11.

또한, 상기 전해조(11)는 기본적으로 절연처리되어 있다. The electrolytic cell 11 is basically insulated.

Here, the present invention has a structure in which insulating portions 12a and 12b are formed at both ends of the electrode plate 12, respectively. In forming the insulating parts 12a and 12b, a polymer or the like is used at both ends of the electrode plate 12, that is, at positions corresponding to the inlet 11a and the outlet 11b of the electrolytic cell 11 of the reactor 10. To form a coating.

전해조(11)의 유입구(11a)와 유출구(11b)의 전류 누설량은 누설전류의 누설경로의 길이에 해당하는 저항에 반비례하므로, 소정의 길이를 가지는 절연부를 형성하여 누설 전류의 양을 감소시킬 수 있는 것이다. Since the amount of current leakage between the inlet 11a and the outlet 11b of the electrolytic cell 11 is inversely proportional to the resistance corresponding to the length of the leakage path of the leakage current, an insulation having a predetermined length can be formed to reduce the amount of leakage current. It is.

한편, 본 발명에 따른 반응기는 다른 실시 예로서, 도 3에 도시된 바와 같이, 전극판(13)의 양쪽 단부에 별도의 절연판(13a)(13b)을 구비할 수 있다. Meanwhile, the reactor according to the present invention may be provided with separate insulating plates 13a and 13b at both ends of the electrode plate 13, as shown in FIG.

이 절연판(13a)(13b)은 별도로 마련하여 전극판(13)의 양쪽 단부에 각각 최대한 밀착되게 배치하여 절연판(13a)(13b)과 전극판(13)과의 사이의 간극을 최소화하여 전류 누설량을 줄일 수 있다.
The insulating plates 13a and 13b are separately provided and placed as close as possible to both ends of the electrode plate 13 to minimize the gap between the insulating plates 13a and 13b and the electrode plate 13 to minimize the current leakage. Can be reduced.
