Description

유증기 회수장치{Vapor recovery system}Vapor recovery system

본 고안은 자동차 휘발유 주유시 발생하는 기체상태의 유증기를 흡입펌프를 이용하여 흡입된 유증기를 증발기(Evaporator)를 통과시켜 기름과 물로 액화시키고, 액화된 휘발유와 물을 유수 분리기를 통해 분리하여 물은 외부로 배출시키고 휘발유는 주유배관과 연결하여 유증기의 대기방출로 인한 공해방지는 물론 유증기를 자원화하기 위한 것이다.The present invention liquefies the gaseous vapor generated during gasoline fueling by using a suction pump to pass the evaporator to liquefy oil and water, and separates the liquefied gasoline and water through an oil / water separator. It is discharged to the outside and gasoline is connected to the oil supply pipe to prevent pollution due to the release of air from the atmosphere and to recycle the oil vapor.

그동안 휘발유 주유시 발생하는 유증기는 주유기 내부에 있는 유량계나 급유펌프에 유증기 회수펌프를 연결하여 회수하거나, 모터 하나에 유증기 회수펌프 2개를 연결하여 유증기를 회수하거나, 또는 본 발명자가 발명한 특1999-0084831의 응축방식이 있으나, 이러한 것들은 지하탱크로 회수하기 위한 회수배관이 구비되어야 한다.In the meantime, the oil vapor generated during gasoline fueling is recovered by connecting an oil vapor recovery pump to a flow meter or an oil supply pump inside the oil tanker, or recovering oil vapor by connecting two oil vapor recovery pumps to one motor, or the invention 1999. There is a condensation method of -0084831, but these must be provided with a return pipe for recovery to underground tanks.

따라서 이러한 회수배관의 설치로 인한 공사비의 발생, 판매손실 등이 발생하는데 이러한 금액의 발생 없이 유증기의 대기방출로 인한 공해방지는 물론 유증기의 자원화가 필요하게 되었다.Therefore, the construction cost, sales loss, etc. are generated due to the installation of the recovery pipe, but it is necessary to prevent the pollution caused by the air emission of the vapor and to resource the vapor without the occurrence of such amount.

본 고안은 상기한 종래의 기술의 문제점을 해결하기, 위해 안출된 것으로서,자동차 주유시 발생하는 기체상태의 유증기를 흡입펌프를 이용하여 회수하고, 회수된 유증기를 증발기(Evaporator)를 통과시켜 휘발유와 물로 액화시키고, 액화된 휘발유와 물을 유수 분리기를 통해 분리하여 물은 외부로 배출시키고, 기름은 주유배관과 연결하여 재사용함으로써, 유증기의 대기방출로 인한 공해방지는 물론 유증기를 자원화할 뿐 아니라 지하탱크까지의 회수배관이 필요하지 않게 되어 사용자 측면에서 소요비용의 절감과 액화된 유증기를 판매하게 되어 유증기 회수장치에 대한 보급률을 높이는데 그 목적이 있다.The present invention has been made in order to solve the problems of the prior art described above, recovering the gaseous vapor generated during the fueling of the vehicle by using a suction pump, the recovered vapor is passed through the evaporator (Evaporator) and gasoline and By liquefying with water, liquefied gasoline and water are separated through oil and water separators, water is discharged to the outside, and oil is connected to the oil supply pipes and reused to prevent pollution due to the release of oil vapors, as well as to resource the vapor. The purpose is to increase the penetration rate of the oil vapor recovery apparatus by reducing the required cost and selling the liquefied oil vapor from the user's point of view because no recovery piping to the tank is required.

상기한 과제를 해결하기 위한 본 고안에 의한 유증기 회수장치는, 급유시 발생하는 유증기를 회수펌프로 유증기 회수용 주유노즐과 호스를 통해 회수하고, 회수된 유증기는 증발기를 이용한 액화장치를 통과시켜 액체 상태로 변환시키면 휘발유와 물의 혼합상태로 되는데, 이를 유수분리기를 이용하여 휘발유와 물로 분리하여 휘발유는 급유배관에 연결하여 재사용하고 물은 외부로 배출하여 유증기로 인한 대기오염방지와 유증기의 자원화는 물론 지하탱크까지의 유증기 회수배관이 없어 회수배관 설치비용과 작업기간 내의 영업손실을 방지할 수 있는 특징이 있다.The oil vapor recovery apparatus according to the present invention for solving the above problems, the oil vapor generated during refueling is recovered through the oil refining nozzle and hose for oil vapor recovery with a recovery pump, the recovered oil vapor is passed through a liquefaction device using an evaporator to liquid When it is converted into a state, gasoline and water are mixed, which is separated into gasoline and water by using an oil / water separator, and the gasoline is connected to the oil supply pipe and reused. There is no vapor recovery pipe to the underground tank, so it is possible to prevent the cost of installing the recovery pipe and operating loss within the working period.

또한, 일반적으로 유증기 회수펌프는 베인(Vaine)펌프를 주로 사용하는데 베인의 마모에 따라 유증기 회수량에 큰 차이를 보이는데 베인펌프의 덮개를 투명하 게 하여 소비자가 쉽게 베인의 마모상태를 확인하여 교환할 수 있게 한 특징이 있다.In addition, in general, the steam recovery pump mainly uses a vane pump, and there is a big difference in the amount of vapor recovery depending on the wear of the vane. The vane pump cover is transparent so that consumers can easily check the vane wear state and replace it. There is a feature that makes it possible.

세계는 교또협약에 의해 온실가스의 저감에 대해 정부차원에서 대응하고 있는 실정이다. 본 고안자가 공개번호 특1999-0084831(가솔린 증발가스 회수장치가 부설된 주유기)에서 밝힌 바와 같이 우리나라도 최근 환경부는 대기환경에 관련한 여러 가지의 법을 시행 중에 있다. 특히나 규제 대상에서 제외되었던 휘발성 유기 화합물(VOC)의 배출의 주요시설인 석유정제 및 저장시설, 주유소, 도장시설, 인쇄시설, 세탁시설에 대한 대기환경보존법은 입법이 되어 있는 실정이다.The world is responding to the reduction of greenhouse gases by the Kyoto Convention at the government level. As the inventor revealed in the publication No. 1999-0084831 (lubricator equipped with gasoline boil-off gas recovery device), the Ministry of Environment has recently implemented various laws related to the atmospheric environment. In particular, the legislation of air quality preservation for petroleum refining and storage facilities, gas stations, painting facilities, printing facilities, and laundry facilities, which are the main facilities for the discharge of volatile organic compounds (VOCs), are excluded.

휘발성 유기화합물(VOC)이란, 휘발유, 납사, 벤젠, 유기용제 등을 제조 운반 사용하는 시설에서 증발되어 대기중으로 방출되는 물질로서 지방족 탄화수소와 방향족 탄화수소 등의 복합성분으로 구성되며, 지방족 탄화수소는 질소산화물과 함께 햇빛을 받아 광화학반응을 일으켜 오존 생성에 주원인 물질로 작용할 뿐 아니라 일부 방향족 탄화수소와 할로겐화 탄화수소는 유해물질로 인체에 직접적인 유해를 주기도 한다.Volatile organic compounds (VOCs) are substances that are evaporated and released into the atmosphere in facilities that manufacture, transport and use gasoline, naphtha, benzene, and organic solvents. Aliphatic hydrocarbons are composed of complex components such as aliphatic hydrocarbons and aromatic hydrocarbons. In addition to sunlight, photochemical reactions are the main causes of ozone production, and some aromatic and halogenated hydrocarbons are harmful to the human body.

주발생원별 유기용제 사용량에 따라 그 발생량은 운행중인 자동차에서 배출되는 VOC가 48.1%로 가장 많고, 그 다음이 건축물·차량·산업시설의 도장 32.8%, 주유 및 저장시설 7.6%, 기타 아스팔트 포장·세탁·인쇄 중에서 11.5% 발생하였다.According to the amount of organic solvent used by each main source, the amount of VOC emitted from the cars in operation is the highest with 48.1%, followed by 32.8% painting of buildings, vehicles, and industrial facilities, 7.6% of oil and storage facilities, and other asphalt pavements. 11.5% occurred in washing and printing.

자동차 연료로 사용되는 휘발유는 탄소(C)와 수소(H)의 결합체(탄화수소 (HC))로서 탄소 중에서도 가벼운 것들이 많아서 휘발성이 강하다.Gasoline, used as a vehicle fuel, is a combination of carbon (C) and hydrogen (H) (hydrocarbon (HC)).

따라서 연료 보관, 운송, 주유에 따른 여러 곳에서 증발가스가 발생한다. Therefore, boil-off gas is generated in several places due to fuel storage, transportation, and fueling.

증발가스가 대기중으로 유출되어 햇빛과 반응할 경우 도심을 뿌옇게 하여 시야를 어둡게 하는 광화학 스모그현상을 일으키게 한다.When the evaporated gas is released into the atmosphere and reacts with sunlight, it can blur the city center, causing a photochemical smog phenomenon that darkens the view.

본 고안에 의한 유증기 액화장치는 다음과 같은 효과가 있다.The vapor liquefaction apparatus according to the present invention has the following effects.

하나, 본 고안은 상기에서 서술한 대기오염 원인물질을 대기로의 방출을 방지하기 위해 주유시 발생하는 유증기를 회수할 뿐 아니라, 회수된 유증기를 액화시켜 수분을 제거한 후 재사용하므로 공해방지는 물론 자원을 재활용하는 효과가 있다. However, the present invention not only recovers the oil vapor generated when refueling the air pollutant mentioned above to the atmosphere, but also reuses after removing the water by liquefying the recovered oil vapor to prevent pollution as well as resources. It is effective to recycle.

둘, 본 고안은 상기에서 서술한 것과 같이 지하탱크까지의 회수배관이 없으므로 별도의 공사가 없어 공사금액은 물론 공사로 인한 판매금액의 손실이 없으므로 유증기 회수장치에 대한 보급률을 높이는 효과가 있다.Secondly, the present invention has no recovery pipe to the underground tank as described above, so there is no separate construction cost, and there is no loss of sales amount due to construction, thereby increasing the diffusion rate for the vapor recovery system.

셋, 본 고안은 상기에서 서술한 것과 같이 유증기 회수용 베인펌프의 뚜껑을 투명하게 하여 소비자가 쉽게 베인의 마모상태를 확인하여 교환할 수 있게 함으로 베인의 마모로 인한 유증기 회수량의 변화를 방지하는 효과가 있다.Third, the present invention makes the lid of the oil vapor recovery vane pump transparent as described above, so that consumers can easily check the vane wear and replace it, thereby preventing changes in the amount of vapor recovery due to vane wear. It works.
