The present invention relates to a device that can be used semi-permanently.

본 고안은 간이상수도를 비롯하여 소규모 정수장 전염소처리등 목욕탕, 폐수처리장 방류수, 냉각탑등에서 차아염소산 칼슘 소독용 약품을 자동으로 투입하는 장치로써 구조가 간단하고 신뢰도가 대단히 높으며 아울러 고장을 자동으로 감지할 수 있는 조작 제어장치로 시스템의 고장은 물론 운전상태를 감지할 수 있다. 또한 원수흐름, 물량의 변동에 따라 자동적으로 약품이 투입될 수 있으며 정확한 운전기능시스템이 부착되어 있어 전기료 및 약품을 절감할 수 있으며 역류방지 기능이 있고 배관설치가 간단할뿐 아니라 약품의 소멸 및 투입시기를 쉽게 확인할 수 있으며 일정한 농도의 약품을 장기적으로 주입시켜 안전한 식수를 공급하는데 목적이 있다.The present invention is a device that automatically inputs calcium hypochlorite disinfectant in baths, wastewater treatment effluents and cooling towers such as liver abnormal water, small-scale water purification plant, pre-chlorine treatment, etc. The operating control unit can detect the operating condition as well as the system failure. In addition, the chemicals can be automatically injected according to the flow of raw water and the quantity of water, and the accurate operation function system can be applied to save electricity and chemicals, and the backflow prevention function is simple. The timing can be easily identified and the purpose is to provide safe drinking water by injecting a certain concentration of medicine in the long term.

본 고안은 지하관정 및 전기가 설치된 곳은 차아염소산칼슘 고체인 약품을 액화시켜(물+클로로칼키)정량적으로 약품을 투입하는 시스템이다The present invention is a system for quantitatively injecting chemicals (water + chlorokalky) by liquefying chemicals that are calcium hypochlorite solids where underground pipes and electricity are installed.

주요구성원은 전체운전을 자동 제어하는 자동 소독주입기 약품탱크로 구성되어 있으며 자동소독주입기 판넬에서는 시스템의 고장 등을 포함한 전반적인 운전을 제어하는데 로터리 스위치에 의해서 원하는 운전을 수동, 자동, 정지로 선택할 수있고 운전상태를 확인 할 수 있다.The main members are composed of automatic disinfectant injector chemical tanks that automatically control the whole operation.The automatic disinfection injector panel controls the overall operation including system breakdown. You can check the operation status.

약품탱크에는 약품 용해수가 저장되어 있고 그양을 감지할 수 있는 위치 센서가 있으며 적정량의 범위를 이탈하면 경고 신호가 발생하고 시스템을 일시적으로 중단되며 약품 용해수는 심정펌프에 설치된 유량센서의 신호와 작동하여 솔밸브 또는 급수펌프를 통하여 적정량이 송수관에 공급된다. 또한 약품탱크에는 용해수 농도를 일정하게 유지하기 위해서는 교반하는데 사용되는 송풍기가 부착되어 있고 이것은 시간 설정에 따라 자동으로 작동하며, 청소를 위해 탱크 아래에 퇴수밸브를 연결해 주도록 구성되어 있다. 따라서 본 고안에 의하면 상수도 시설의 노후화 및 항공농약방제 그리고 환경오염, 수질오염, 대기오염 각종 바이러스 등 세균번식으로 수질이 악화되어 수인성전염병 등 질병을 유발시킬수 있는 배수지에 소독할 수 있는 상수도시설에 장기간 일정하게 차아염소산 칼슘을 주입할 수 있어 양질의 식수를 공급하는데 차질이 없도록 만전을 기하는데 있다.The chemical tank contains chemical dissolved water and a position sensor that can detect the amount.If it is out of the proper amount, a warning signal is generated and the system is temporarily stopped.The chemical dissolved water is operated with the signal of the flow sensor installed in the heart pump. The proper amount is supplied to the water pipe through the solenoid valve or feed water pump. In addition, the chemical tank is equipped with a blower which is used to stir to maintain a constant concentration of dissolved water, which automatically operates according to the time setting, and is configured to connect a drain valve under the tank for cleaning. Therefore, according to the present invention, water quality deteriorates due to aging of water supply facilities, aviation pesticide control, and bacterial propagation such as environmental pollution, water pollution, air pollution, various viruses, and so on. Calcium hypochlorite can be injected regularly over a long period of time, so that there is no problem in supplying high quality drinking water.

Description

상수도용 소독약품 자동주입 시스템{Automatic system for supplying the disinfection chemicals in waterworks}Automatic system for supplying the disinfection chemicals in waterworks

본고안은 집단 급수시설(상수도). 하수도. 폐수처리시설에 살균 소독을 목적으로 주입하고 있는 클로로칼키(통상 염소라 칭한다)This bill is group water supply facility (waterworks). sewer. Chlorokalki (commonly called chlorine) that is injected into wastewater treatment facilities for the purpose of disinfection.

간이상수도 시설에 전기를 이용하여 자동조절방식으로 장기간 약품을 주입하여 안정적으로 양질의 식수를 공급하기 위한 장치에 관한 것이다.The present invention relates to a device for stably supplying high-quality drinking water by injecting drugs for a long time by an automatic control method using electricity to a liver abnormal water supply facility.

일반적으로 간이상수도 시설은 주로 산간오지지역에 위치해 있어 당연히 맑은물이 공급되는 것으로 인식되어 지금까지는 별관심없이 소외되어 왔던 시설이다.In general, the Kansang water supply facility is mainly located in the mountainous outland area, so it is recognized as a clear water supply, and it has been neglected until now without any interest.

그러므로 당연히 간이상수도 시설에 소독약품을 주입할 수 있는 시설이 미흡한 실정이며, 또한 배수지 시설이 주로 산간 오지에 위치해 있어 주변환경도 열악한데다 현재 개발된 염소 투입 장치들을 사용하는데 문제점이 많아 적정 주입하기가 어려운 실정이며 수질분석 결과 기준치초과 및 미달되어 수인성 전염병이 자주 발생되고 있어 간이 상수도에 소독약품 주입은 절실한 상태이다.Therefore, of course, there are insufficient facilities for injecting disinfecting chemicals into the liver abnormal water supply facilities, and since the drainage facilities are mainly located in the mountainous outskirts, the surrounding environment is poor, and there are problems in using the currently developed chlorine input devices. It is difficult and the water quality analysis results in exceeding or under the standard, waterborne infectious diseases frequently occur, so the disinfectant injection into the drinking water is urgently needed.

종래에 기 개발되어 사용되는 방식을 살펴보면 많은 문제점을 가지고 있어 이를 자세히 나열하면 다음과 같다.Looking at the method that has been developed and used in the prior art has a number of problems listed in detail as follows.

첫번째 액체 염소투입 방식은The first liquid chlorine injection method

액체염소(이산화염소)는 인체에 치명적인 영향을 줄뿐아니라 관리상 문제점이 많아 전문취급자가 없는 간이상수도에 보급이 극히 위험하므로 사용하기가 어렵다.Liquid chlorine (chlorine dioxide) not only has a fatal effect on the human body, but also has a lot of management problems, so it is difficult to use because it is extremely dangerous to supply to liver abnormal water without a professional handler.

두번째 고체상태 투입방식은The second solid state input method

미량투입이 어려움으로 정확한 농도관리가 안되며 상근관리자도 없는 상태에서 자주 약품을 보충해야 하며 고장율이 잦아 간이상수도 여건에 맞지 않으며 고체인 클로로칼키가 수분과 함께 막힘현상이 일어난다.It is difficult to precisely manage the concentration due to the difficulty in the administration of trace amount, and it is necessary to replenish the medicine frequently in the absence of the full-time manager. The frequent failure rate is not suitable for the condition, and the solid chlorokalki is clogged with water.

세번째 분말 수동조절 방식은The third powder manual control method

약품특성상 칼륨 성분에 의해 응고가 되어 주입구 막힘현상이 자주 발생되어 제품에 대한 신뢰성이 없으며 구조상 정량주입이 어렵고 저장탱크가 작아 장기간 약품 주입이 어렵다.Due to the characteristics of the drug, solidification is caused by the potassium component, which causes frequent clogging of the injection port, which is not reliable for the product, and difficult to quantitatively inject into the structure and the storage tank is small, making it difficult to inject the drug for a long time.

또한 재질 구조상 노천에 방치시 동결 및 수명이 짧으며 저장 탱크가 기밀용기로 되어 있지 않아 염소가스가 휘발되어 약품 농도가 저하되며 물의수량에 따라 주입량을 조절할 수 없음으로 정밀한 농도유지관리를 할 수 없다.In addition, freezing and lifespan are short when left in the open air due to the material structure, and because the storage tank is not airtight, chlorine gas is volatilized to reduce the chemical concentration, and it is impossible to control the concentration precisely according to the quantity of water. .

야간등 배수지 만수시에도 약품이 계속해서 주입되므로 과 주입에 의한 위험발생이 뒤따른다.Even when the drainage basin is full at night, chemicals are continuously injected, resulting in overdose.

본고안은 상기와 같은 종래의 문제점을 해소하기 위하여 고안된 것으로써 기밀로된 저장용기에 고체상태로 된 염소와 물을 혼합하여 일정 농도의 수용액으로 만든후 유량변동이 예측되는 상수용원수에 약품을 투입하는데 있어서 가장 중요한 기술은 물의 양에 따라 자동적으로 일정농도의 혼합된 약품수용액을 조절할 수 있도록 만든 장치이며소독용 약품의 양을 감지하고 시스템 이상유무를 자동으로 확인할 수 있으며 경고등이 설치되어 있어 사용자에게 경보신호를 할 수 있는 장치이다.This paper is designed to solve the above-mentioned problems. The chlorine and water in solid state are mixed with airtight storage container to produce a certain concentration of aqueous solution, and then the chemicals are applied to the purified water. The most important technology in the input is a device that can adjust the mixed concentration of chemicals in a certain concentration automatically according to the amount of water.It can detect the amount of disinfecting chemicals and check the system abnormality automatically. It is a device that can give alarm signal.
