Description

주유소 휘발성 증발가스의 회수장치{Collection Device Of Volatility Gas With An Oil Station}Collection device of volatility gas with an oil station

본 발명은 주유소 등의 유류 저장고에 유류를 인입,출시 및 차량 주유시에 유류 저장고, 차량 연료 탱크로 부터 증발되는 휘발성 유기가스를 회수 재활용시키는 주유소 휘발성 증발가스의 회수장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a gas station volatile vaporized gas recovery apparatus for recovering and recycling volatile organic gas evaporated from an oil cellar and a vehicle fuel tank when oil is introduced into and released from an oil cellar such as a gas station.

종래에는 도 1에 도시한 바와 같이 유조차 탱크(1)에서 지하 유류 저장조(2)로 급유할 때 유류가 급유된 체적 만큼 증발가스가 유조차 탱크(1)로 회수되어 재생 또는 소각처리하는 것이 있었고, 또한 상기 증발가스를 진공펌프 및 자동밸브등을 이용, 흡수탑(3)으로 강제 유도하여 휘발성 유류는 흡착되게 하고, 잔류가스는 배출시키는 구성과 냉각탑(4)에 의해 액화 회수시키는 장치가 있었다.Conventionally, as shown in FIG. 1, when the oil is refueled from the tank 1 to the underground oil storage tank 2, the vaporized gas is recovered to the tank 1 and regenerated or incinerated as much as the volume of the oil being refueled. In addition, there was a configuration in which the evaporated gas was forced to the absorption tower 3 by using a vacuum pump, an automatic valve, and the like, so that volatile oil was adsorbed, and residual gas was discharged.

그러나, 상기 유류 저장조(2)에서 유조차 탱크(1)로 증발가스를 회수하는 것은 압력 조절관(5)을 통하여 역 유입되는 공기등에 의해 유류 저장조(2)내의 압력이 낮아져 효율적인 회수가 이루어 지지 못한 문제점이 있었고, 상기 증발가스를 흡착탑(3) 및 냉각탑(4)으로 진공펌프 및 자동밸브를 이용, 강제 유도하는 것은 낮은 비점의 가연성 가스처리 사용에는 현실적으로 적합하지 못한 문제점이 있었다However, the recovery of the boil-off gas from the oil reservoir 2 to the oil tank 1 is not achieved efficiently because the pressure in the oil reservoir 2 is lowered due to the air flowing back through the pressure control pipe 5. There was a problem, and the forced introduction of the boil-off gas into the adsorption tower 3 and the cooling tower 4 by using a vacuum pump and an automatic valve was not practically suitable for the use of low boiling point flammable gas treatment.

본 발명은 상기한 문제점을 해결하고자 안출된 것으로서, 본 발명의 목적은 주유소의 유류 저장조내 증발가스를 자연스럽게 유도하여 액화 재생할 수 있도록한 회수장치를 제공함에 있다.The present invention has been made to solve the above problems, an object of the present invention is to provide a recovery apparatus that can naturally induce the liquefied and regenerated evaporation gas in the oil storage tank of the gas station.

본 발명의 다른 목적은 주유소에서 각종 차량의 연료 탱크에 연료를 공급할 때 상기 연료 탱크내의 증기가스를 유류 저장조내로 회수시키는 장치를 부가적으로 제공함에 있다.Another object of the present invention is to additionally provide an apparatus for recovering steam gas in a fuel tank into an oil storage tank when fuel is supplied to fuel tanks of various vehicles at a gas station.

이와 같은 목적을 달성하기 위하여 본 발명은 주유소의 유류 저장조내 증발가스를 냉각장치의 접촉볼과 가열판상에 충진된 활성탄에 흡착 회수하는 장치를 연결, 장치 하였고, 상기 주유소의 주유기에는 유류 공급관과는 별도로 유류 조장조와 차량 연료 탱크 사이에 증기가스 흡입관을 연결하고, 이 흡입관상에 흡입펌프를 연결한 것이다.In order to achieve the above object, the present invention is connected to the apparatus for adsorbing and recovering the evaporated gas in the oil storage tank of the gas station to the contact ball of the cooling device and the activated carbon filled on the heating plate, and the oil supply pipe of the gas station is In addition, a steam gas suction pipe is connected between the oil storage tank and the vehicle fuel tank, and a suction pump is connected to the suction pipe.

도 2는 본 발명의 주유소 휘발성 가스 회수장치의 개괄적인 개략도이고, 도 3은 본 발명의 주 요부를 분리하여 확대 도시한 상세도면으로서, 도시된 바와 같이 주유소에는 유류 저장조(20)가 지하에 밀폐 설치된채 지상의 차량 주유기(21)와 급유관(22)으로 연결되어 있고, 또한 상기 유류 저장조(20)는 유조차 탱크(10)로 부터 유류를 공급 받을 수 있도록 공급관(11)이 매설되어 있다.Figure 2 is a schematic schematic view of the gas station volatile gas recovery apparatus of the present invention, Figure 3 is a detailed view of the main portion of the present invention separated and enlarged, as shown, the oil reservoir 20 is sealed in the gas station underground It is installed and connected to the vehicle oil tanker 21 and the oil supply pipe 22 on the ground, and the oil storage tank 20 has a supply pipe 11 embedded so that even oil can be supplied from the tank 10.

이와 같은 주유소 형태에 있어서, 지하 유류 저장조(20)의 상면 내벽에 배설된 휘발성 증기가스 배출관(31)는 유류 회수기(30)로 배관되어 있고, 상기 유류 회수기(30)에는 상면에 휠타를 겸한 단열층(32)과 외면에 보온층(33)이 피복된 냉각장치(34)가 장치되어, 그 아래는 접촉용해를 위한 반구형 볼(35)이 층을 이루고 있고, 상기 단열층(32)의 상측에는 가열판(40)이 배설된 사이사이로 흡착을 위한 활성탄(41)이 충진된 구조로 이루어져 있다.In such a gas station form, the volatile vapor gas discharge pipe 31 disposed on the inner wall of the upper surface of the underground oil storage tank 20 is piped to the oil recovery unit 30, and the oil recovery unit 30 has a heat insulating layer that doubles as a filter. Cooling device 34 having a heat insulating layer 33 coated on the outer surface 32 and 32 is formed below, and a hemispherical ball 35 for contact melting is layered. It is made of a structure filled with activated carbon 41 for adsorption between the 40 is excreted.

또한, 상기 주유기(21)에는 상기 급유관(22)과는 별도로 유류 저장조(20)와 차량 연료탱크 사이 가스 흡입관(23)을 연결하고, 이 흡입관(23)상에 흡입펌프(24)를 연결한 구조로 이루어져 있다.In addition, the gas tank 21 is connected to the gas suction pipe 23 between the oil storage tank 20 and the vehicle fuel tank separately from the oil supply pipe 22, and the suction pump 24 is connected to the suction pipe 23. It consists of a structure.

미설명 부호 36은 유류 회수관이고, 37은 물이며, 38, 42, 43은 밸브이다.Reference numeral 36 is an oil return pipe, 37 is water, and 38, 42, 43 are valves.

이와 같이 구성된 본 발명의 작용를 설명하면, 유조차 탱크(10)로 부터 유류 저장조(20)로 급유될 때 급유되는 체적만큼 상기 유류 저장조(20)내에 휘발성 증기가스의 압력이 생기며, 상기 증기가스는 자연스럽게 배출관(31)을 통하고, 또한 지상의 주유기(21)를 통하여 각종 차량의 연료 탱크에 유류를 급유할 때, 이 연료탱크로 부터 발생된 증기가스의 압력으로 또는 흡입펌프(24)를 구동하여 흡인관(23)을 통해 지하 저장조(20)로 흡인된 증기가스가 상기 배출관(31)을 통하여 각각 유류 회수기(30)로 배출된다.Referring to the operation of the present invention configured as described above, the pressure of the volatile vapor gas in the oil storage tank 20 is generated by the volume of oil even when the oil is refueled from the tank 10 to the oil storage tank 20, the steam gas is naturally When oil is supplied to fuel tanks of various vehicles through the discharge pipe 31 and through the ground oil tank 21, the suction pump 24 is driven by the pressure of the steam gas generated from the fuel tank or Steam gas drawn into the underground storage tank 20 through the suction pipe 23 is discharged to the oil recovery unit 30 through the discharge pipe 31, respectively.

이와 같이 배출되는 휘발성 증기가스는 냉각장치(34)에 의해 냉각되어 있는 반구형 볼(35)층을 접촉 통과될 때 일부 냉각 액화되고, 잔여 증기가스의 휘발성 물질은 가열판(40)상에 충진되어 있는 활성탄(41)층을 통과 하면서 활성탄(41)에 흡착되며, 기체상의 증기만 밸브(42)를 통하여 배출된다.The volatile vapor gas discharged as described above is partially liquefied when it passes through the hemispherical ball 35 layer cooled by the cooling device 34, and the volatile substance of the remaining vapor gas is filled on the heating plate 40. While adsorbed on the activated carbon 41 while passing through the layer of activated carbon 41, only gaseous vapor is discharged through the valve 42.

이때, 상기 활성탄(41)의 표면상에 휘발성 물질이 흡착되면서 점차 흡착 효율이 낮아지게 되면, 상기 대기로의 배출 밸브(42)를 닫음과 동시에 순환 밸브(43)를 열고, 가열판(40)에 전원을 접속하여 활성탄(41)을 가열하면, 상기 활성탄은 건조 재생되고, 휘발성 유기화합물의 일부는 액화되어 저온의 냉각부로 액상으로 흘러 내려가고, 일부는 가스로 상기 배출관(31')으로 재 순환되며 액화 회수 된다.At this time, when the adsorption efficiency gradually decreases as the volatile substance is adsorbed on the surface of the activated carbon 41, the discharge valve 42 to the atmosphere is opened and the circulation valve 43 is opened to the heating plate 40. When the power is connected and the activated carbon 41 is heated, the activated carbon is dried and regenerated, and a part of the volatile organic compounds is liquefied and flows down into the liquid phase to a low temperature cooling part, and part is recycled to the discharge pipe 31 'with gas. And liquefaction is recovered.

이와 같이 냉각 액화물 및 유류는 유수 분리되어 유류는 회수관(36)을 통하여 저장조로 회수되고, 물(37)은 자동밸브(38)를 통하여 배출된다.As such, the cooling liquefied liquid and the oil are separated from the oil and water, the oil is recovered to the storage tank through the recovery pipe 36, and the water 37 is discharged through the automatic valve 38.

이상 설명한 바와 같이, 본 발명은 각종 차량의 연료 탱크에 연료를 공급할 때, 상기 연료 탱크내의 증기가스를 유류 저장조내로 회수시킴과 동시에, 유류 저장조내 증발가스를 자연스럽게 회수기(30)로 유도하여 액화 재생할 수 있도록한 것으로서, 대기 오염을 방지함과 동시에, 자원절약에 크게 기여한 효과가 있고, 상기 회수장치의 구조가 간편하여 저렴하게 설비할 수 있고, 특히 흡착물질의 반복 재활용 할 수 있도록 되어 있어 경제성이 있는 효과가 있다.As described above, when the fuel is supplied to the fuel tanks of various vehicles, the present invention recovers the vapor gas in the fuel tank into the oil storage tank, and naturally induces the evaporated gas in the oil storage tank to the recoverer 30 to liquefy and regenerate. As a result, it is possible to prevent air pollution and contribute greatly to resource saving. The structure of the recovery device is simple and can be installed at low cost, and in particular, it is possible to repeatedly recycle the adsorbed material. It has an effect.
