Description

산성용액 누설 감지 장치{Acidic solution leakage sensor}[0001] Acidic solution leakage sensor [0002]

본 발명은 산성용액 누설 감지 장치에 관한 것으로, 특히 황산, 염산, 질산, 불산 등과 같은 강산성의 유독성 화학 용액의 누설을 감지하기 위한 산성용액 누설 감지 장치에 관한 것이다.
The present invention relates to an acid solution leakage detecting apparatus, and more particularly, to an acid solution leakage detecting apparatus for detecting a leakage of a strong acidic toxic chemical solution such as sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, and the like.

본 출원인은 이미 여러건의 등록 특허(10-0909242, 10-0827385 등)에서 테이프 형태로 되어 누수가 발생하기 쉬운 위치에 설치함으로써 누수 발생을 쉽게 감지할 수 있도록 하는 테이프 형태의 누수감지센서를 제안한 바 있다.The applicant of the present invention has already proposed a tape-like leak detection sensor that can easily detect the occurrence of leakage by providing a tape-like shape in a number of registered patents (10-0909242, 10-0827385, etc.) have.

도1 및 도2에 도시한 바와 같이 이러한 누수감지센서(100)는 하부접착층(120), 베이스필름층(110), 상부보호필름층(130)이 저면에서 상방으로 순차적으로 적층되어 이루어진다.1 and 2, the leak sensor 100 includes a lower adhesive layer 120, a base film layer 110, and an upper protective film layer 130 sequentially stacked on the bottom surface.

하부접착층(120)은 누수가 발생되는 곳에 부착하기 위한 것으로, 접착 테이프 형태로 구성되고, 베이스필름층(110)은 도전라인(111,112)이 상부에 형성되기 위한 층으로서, 도전라인(111,112)의 패턴을 인쇄 방식에 형성하기 위해 PET, PE, PTFE, PVC 또는 기타 테프론 계열의 재질의 필름으로 형성된다.The base film layer 110 is a layer in which the conductive lines 111 and 112 are formed on the upper part and the upper part of the conductive lines 111 and 112 It is formed of a film made of PET, PE, PTFE, PVC or other Teflon series to form a pattern in a printing method.

그리고, 도전라인(111,112)은 베이스필름층(110)의 상부표면에서 서로 이격되어 길이방향으로 평행하게 스트립 형태로 배치되며, 도전성 잉크 또는 은(Silver) 화합물로 인쇄된다.The conductive lines 111 and 112 are arranged in strips parallel to each other in the longitudinal direction, spaced from each other on the upper surface of the base film layer 110, and printed with a conductive ink or silver compound.

상부보호필름층(130)은 베이스필름층(110)의 상부에 적층되어 도전라인(111,112)을 외부의 자극으로부터 보호하기 위한 층으로서, 베이스필름층(110)과 같이 PET, PE, PTFE, PVC 또는 기타 테프론 계열의 재질로 형성되며, 도전라인(111,112)에 해당하는 위치에 일정간격마다 센싱홀(131)이 관통되어 형성되도록 구성된다.The upper protective film layer 130 is a layer for protecting the conductive lines 111 and 112 from external stimuli by being laminated on the base film layer 110. The upper protective film layer 130 may be made of PET, Or other Teflon-based materials. The sensing holes 131 are formed at predetermined intervals in positions corresponding to the conductive lines 111 and 112, respectively.

따라서, 누수가 발생하면, 누수가 발생된 위치의 센싱홀(131)을 통해 수분이 유입되어 두 도전라인(111,112)이 수분에 의해 통전되며, 원격의 제어기가 그 통전상태 즉 폐회로가 형성되는 상태를 파악하여 누수여부를 감지하고, 그에 따른 경보를 발생할 수 있게 된다.Therefore, when water leakage occurs, water is introduced through the sensing hole 131 at the position where the water leakage occurs, so that the two conductive lines 111 and 112 are energized by moisture, and the remote controller is in the energized state So that it is possible to detect the leakage and to generate an alarm accordingly.

그런데, 이러한 종래의 필름형 누수감지센서(100)는 물은 물론 도전성을 갖는 황산,염산, 질산, 불산 등의 강산성의 유독성 화학 용액도 검출할 수 있지만, 이를 강산성의 액체가 저장된 옥내외의 저장조 또는 배관에 설치되어 산성용액의 누설을 감지하는 목적으로 사용하는 경우에 습기나 빗물, 결로, 눈, 수증기 등에 노출되어도 경보가 발생할 수 있어서 오작동의 결과를 가져온다.
However, such a conventional film type leak sensor 100 can detect not only water but also strong acidic toxic chemical solutions such as sulfuric acid, hydrochloric acid, nitric acid, and hydrofluoric acid having conductivity, If it is installed in piping and used for the purpose of detecting leakage of acid solution, alarm may occur even when exposed to moisture, rain, condensation, snow, water vapor, etc., resulting in malfunction.

본 발명은 종래의 이러한 문제점을 해결하고자, 강산성이 액체가 누설되는 경우에만 도전라인이 통전되어 동작하도록 한 산성용액 누설 감지 장치를 제공하는데 그 목적이 있다.
SUMMARY OF THE INVENTION It is an object of the present invention to provide an acid solution leakage detecting apparatus which is operated by energizing a conductive line only when a strongly acidic liquid is leaked.

본 발명의 첨부한 도면을 참조하여 상세히 설명한다.The present invention will be described in detail with reference to the accompanying drawings.

도3은 본 발명의 구조를 보인 도이고, 도4는 본 발명의 측단면도로서, 베이스필름층(110), 부착층(120), 상부보호필름층(130)의 구조는 종래와 동일하므로, 본 발명에서 적용된 코팅층(200)을 중심으로 설명한다.4 is a cross-sectional view of the present invention. Since the structures of the base film layer 110, the adhesion layer 120, and the upper protective film layer 130 are the same as those of the conventional art, The coating layer 200 applied in the present invention will be mainly described.

먼저, 유독물인 산성용액은 물과 같이 전기적 도전성을 가지고 있으며, 토양이나 대기로 누설되는 경우에는 수질오염, 토양오염, 대기오염 등이 발생함으로써 물적피해는 물론 인적피해까지 심각하게 발생하게 된다.First, the toxic acidic solution has electric conductivity like water, and when it leaks to the soil or the air, water pollution, soil pollution, air pollution, etc. occur, resulting in material damage as well as personal injury.

따라서, 이러한 산성용액의 누설을 빠르고 저비용으로 감지할 수 있어야 하는데, 이를 위해 본 발명은 도전라인(111,112)이 형성된 베이스필름층(110)의 상부면에는 황산, 염산, 질산, 불산 등과 같은 강산성의 유독성 화학 용액, 즉 산성용액에 의해 용해되는 코팅층(200)이 형성되며, 이러한 코팅층(200)은 베이스필름층(110)의 상부면 전체에 도포되거나 또는 도전라인(111,112)만을 외부로부터 격리시키기 위하여 도전라인(111,112)이 형성된 부위에만 코팅이 이루어질 수 있다.Therefore, it is necessary to detect leakage of such an acidic solution quickly and at low cost. To this end, the present invention is characterized in that the upper surface of the base film layer 110 on which the conductive lines 111 and 112 are formed is coated with a strong acid such as sulfuric acid, hydrochloric acid, A coating layer 200 is formed which is dissolved by a toxic chemical solution, that is, an acidic solution, and the coating layer 200 is applied to the entire upper surface of the base film layer 110, or only the conductive lines 111 and 112 are isolated from the outside The coating can be made only on the portion where the conductive lines 111 and 112 are formed.

코팅층(200)은 산성용액에 의해 쉽게 녹아 용해될 수 있는 에나멜, 멜라닌, 우레탄, 기타 합성수지 등이 분사에 의해 얇은 막 형태로 코팅되어 형성될 수 있다.The coating layer 200 may be formed by coating with a thin film by spraying enamel, melanin, urethane or other synthetic resin which can be easily dissolved by an acidic solution.

상기 코팅층(200)의 상부로는 센싱홀(131)이 형성된 상부보호필름층(130)이 적층되는데, 이러한 상부보호필름층(130)은 선택적으로 적층될 수 있다.An upper protective film layer 130 having a sensing hole 131 is stacked on the coating layer 200. The upper protective film layer 130 may be selectively stacked.

즉, 외부환경에 영향을 많이 받는 옥외에는 코팅층(200)을 보호하기 위하여 상부보호필름층(130)이 적층되는 것이 좋으며, 옥내에서는 여건에 따라 상부보호필름층(130)이 적층되거나 또는 적층되지 않을 수 있다.That is, in order to protect the coating layer 200 from being exposed to the external environment, the upper protective film layer 130 may be laminated, and depending on circumstances, the upper protective film layer 130 may be laminated or laminated .

본 발명에서는 상부보호필름층(130)이 적층된 상태를 예로들어 설명한다.In the present invention, the upper protective film layer 130 is stacked.

따라서, 본 발명이 산성용액이 이동하는 배관의 이음새 부분이나 저장조의 외부에 부착되거나 감겨서 설치되는 경우에 산성용액의 누설이 발생되어 도5에서와 같이 본 발명의 상부보호필름층(130)의 상부면에 산성용액(300)이 위치하여 센싱홀(131)로 유입되면, 도6에서와 같이 코팅층(200)이 산성용액에 의해 용해되어 도전라인(111)과 도전라인(112)이 통전된다.Accordingly, when the present invention is applied to a joint portion of a piping through which the acidic solution moves or to the outside of the storage tank, the acidic solution leaks to form the upper protective film layer 130 of the present invention When the acid solution 300 is positioned on the upper surface and flows into the sensing hole 131, the coating layer 200 is dissolved by the acid solution as shown in FIG. 6, and the conductive line 111 and the conductive line 112 are energized .

원격의 제어기는 이러한 통전상태를 확인하여 산성용액의 누설 상태를 확인할 수 있는 것이다.
The remote controller can confirm the leakage state of the acid solution by confirming the energized state.

도7은 본 발명의 다른 실시예를 보인 도로서, 코팅층(210)이 상보보호필름층(130)의 상부면에 도포된 형태를 보인 것이다.7 is a view showing another embodiment of the present invention in which the coating layer 210 is coated on the upper surface of the complementary protective film layer 130. FIG.

그러므로, 산성용액이 누설된 경우에 가장 상부층인 코팅층(210)을 용해시킨 후 센싱홀(131)을 통해 유입되어 도전라인(111,112)이 서로 통전이 됨으로써 누설을 감지할 수 있는 것이다.
Therefore, when the acidic solution is leaked, the coating layer 210, which is the uppermost layer, is dissolved and flows through the sensing hole 131, so that the conductive lines 111 and 112 are energized with each other to detect leakage.

도8은 또다른 실시예를 보인 도로서, 베이스필름층(110)이나 상부보호필름층(130)의 전체면에 도포하는 것이 아니라 센싱홀(131)만을 메꾸는 형태로 코팅부위(220)가 형성되어 산성용액이 코팅부위(220)를 용해시켜 도전라인(111,112)을 통전시키게 된다.
8 is a view showing another embodiment of the present invention. Instead of coating the entire surface of the base film layer 110 or the upper protective film layer 130, So that the acid solution dissolves the coating portion 220 to conduct the conductive lines 111 and 112.

이러한 도7과 도8의 구조는 종래의 기술에서와 같이 적층이 완료된 기존의 누수감지센서(100)를 그대로 이용하여 상부보호필름층(130)의 상부표면에 코팅액을 도포하거나 또는 센싱홀만을 코팅액에 의해 메꾸는 공정만을 추가하여 산성용액 누설 감지 장치를 용이하게 제조할 수 있다.7 and 8, the coating solution is coated on the upper surface of the upper protective film layer 130 by using the existing leak detection sensor 100, which has been stacked as it is, It is possible to easily manufacture an acidic solution leakage sensing device by adding only the step of etching by the etching process.

물론, 가장 바람직하게는 외부의 환경에 따른 영향을 가장 최소화하고, 또한 도전라인을 외부로부터 완전하게 격리시키기 위하여 도3에서와 같은 구조를 가지는 것이 가장 좋다.
Of course, it is most preferable that the structure as shown in Fig. 3 is the most preferable in order to minimize the influence due to the external environment and completely isolate the conductive line from the outside.
