Description

부취제주입장치{ODORANT SUPPLIER}Deodorant Injection Device {ODORANT SUPPLIER}

본 발명은 액화천연가스(LNG)를 기화하여 사용하는 곳에서 그 가스의 누출여부를 후각에 의하여 감지할 수 있도록 인위적으로 첨가하는 부취제를 그 첨가장치와 함께 구성된 부취제 저장용기에 안전하고 경제적인 방법으로 부취제를 주입할 수 있는 장치에 관한 것이다.The present invention is a safe and economical in the odor storage container configured with the additive device to add an odorant artificially added to the smell to detect whether the gas leaks in the place where the liquefied natural gas (LNG) is used The present invention relates to a device capable of injecting odorants in a phosphorus method.

일반적으로 LNG는 공업용과 가정용 연료로서 널리 사용되고 있으며 그 사용에 있어 안전성, 간편성, 경제성 등으로 인하여 날로 그 사용이 증가하고 있다.In general, LNG is widely used as industrial and domestic fuel, and its use is increasing day by day due to safety, simplicity, and economic efficiency.

국제적으로 탄소화합물 규제에 따른 규정을 강화하고 있는 가운데 국내에서는 대기환경보전법에 탄소화합물의 배출을 규제함으로서 청정연료이면서 탈 석유정책에 부합하는 대체연료로서 LNG는 각종 연료로 개발되고 있으며 움직임은 더욱 가속화되고 있다.While regulations on carbon compounds are being strengthened internationally, LNG is being developed into various fuels as a clean fuel and an alternative fuel that meets the de-oil policy by regulating the emission of carbon compounds under the Atmospheric Environment Conservation Act. It is becoming.

특히, LNG는 차량연료로 개발되어 천연가스버스에 연료를 보급하기 위한 L-CNG(Liquefied Compressed Natural Gas)충전소가 건립되었으며 보급활성화가 예상되고 있다. 또한, 도시가스 배관망이 설치되지 않았거나 향후에도 지형적 어려움으로 인하여 배관이 설치되기 어려운 지역에는 LNG를 탱크로리를 이용하여 액상의 상태로 운송하고 현지에 공급시설을 갖추고 기화하여 사용처에 공급하는 방식을 채용하고 있어 LNG 의 이용 또한 더욱 확대될 전망이다.In particular, LNG has been developed as a vehicle fuel, and the L-CNG (Liquefied Compressed Natural Gas) filling station for fueling natural gas buses has been established and is expected to be activated. Also, in areas where the city gas pipe network is not installed or where pipes are difficult to install due to geographical difficulties in the future, LNG is transported in a liquid state using tank lorry, and a local supply facility is vaporized and supplied to the user. LNG is also expected to expand further.

LNG는 가스전에서 직접 기체상태로 채취하여 대량의 운반과 저장을 위하여 영하 162℃로 냉각, 압축, 액화시켜 부피를 1/600으로 줄인 메탄이 주성분인 무색,무취의 액체이다.LNG is a colorless, odorless liquid whose main component is methane, which is collected in gaseous form directly from the gas field and cooled, compressed, and liquefied to minus 162 ℃ for mass transportation and storage.

상기에서 나열한 LNG의 특성중 가장 큰 단점은 가연성 가스로서 대기압 상태에서 기체로 존재하며 무색, 무취이므로 오감에 의한 식별이 어렵고, 공기와 혼합될 경우 그 폭발농도가 낮아 공기중 5∼15%의 농도만으로도 폭발, 연소의 위험이 항상 존재하게 되므로 동 가스의 누출은 대단히 위험하며 종래의 많은 사고사례에서 보듯이 그 파괴력은 우리사회에 많은 손실을 주고있다.Among the characteristics of LNG listed above, the biggest disadvantage is the flammable gas, which exists as a gas at atmospheric pressure and is colorless and odorless, making it difficult to identify by the five senses. Since there is always a risk of explosion and combustion alone, the leakage of copper gas is very dangerous, and as shown in many conventional accidents, the destructive power is causing a great loss to our society.

이에 "도시가스 사업법"에서는 미량의 누출에서도 후각에 의해 쉽게 인지할 수 있도록 부취제를 혼입하도록 규정하고 있다.Accordingly, the "City Gas Business Law" stipulates that odorants should be mixed so that even small amounts of leaks can be easily recognized by smell.

액화석유가스(LPG)의 경우 주로 액상의 상태로 유통되며 비교적 끓는점이 높아(프로판:-42℃ , 부탄 :-0.5℃ ) 부취제를 액상으로 첨가, 혼합하여 유통하므로 부취제의 주입에 큰 문제가 대두되지 않는다. 그러나 LNG의 경우 끓는점이 낮아(-162℃) 부취제를 첨가할 경우 결빙되어 관계시설에 위험을 초래하게 되므로 기체상태로 기화한 가스에 주입시설(Odorizer)을 이용하여 혼합하고 있다.Liquefied petroleum gas (LPG) is mainly distributed in the liquid state and has a relatively high boiling point (propane: -42 ° C, butane: -0.5 ° C). Is not emerging. However, in case of LNG, the boiling point is low (-162 ℃), so if odorant is added, it is frozen and causes danger to related facilities. Therefore, it is mixed with gaseous gas vaporized by using Odorizer.

종래의 부취제 충전은 [도1]에 도시된 바와 같이 부취제 탱크(13) 와 수입탱크로리(11)에 수입배관(22)과 균압배관(21)을 연결하고 수입배관(22)에 펌프 또는 균압배관(21)에 압축기를 설치하여 부취제 탱크(13)에 이입, 저장하고 필터(17)를 통해 정제된 부취제를 정량펌프(16)로 도입배관(26)에 가압, 공급하여 주공급관(27)에 설치된 노즐(19)로 제조가스(31)에 분사하여 부취제를 첨가하여 혼합가스(32)를 제조한다. Conventional odorant filling is connected to the import pipe 22 and the equalization pipe 21 to the odorant tank 13 and the import tank lorry 11 as shown in FIG. The compressor is installed in the equalization pipe 21 to be introduced and stored in the odorant tank 13, and the odorant purified through the filter 17 is pressurized and supplied to the introduction pipe 26 by the metering pump 16. The mixed gas 32 is manufactured by spraying the manufacturing gas 31 with the nozzle 19 provided in the 27, and adding a odorant.

이와 같은 탱크로리를 이용한 부취제수입은 1회에 약 1,000~10,000리터의 대용량을 수입하는 시설에 적합하다. 현재 또는 향후 보급되는 부취제 저장량 10~300리터의 소, 중규모 LNG공급설비에는 그 규모가 맞지 않아, 이를 위해 적당한 용기(예컨대, 18리터 플라스틱용기등)에 부취제를 채취하여 LNG공급설비의 부취제 저장용기에 깔때기 등을 설치하고 주입하여야 하므로 심한 악취는 물론 부취제의 비산이나, 흘러 넘침으로 인해 상당한 위험요소를 내포하게 되거나 탱크로리를 이용한 비경제적인 방법을 채택하여야 할 것이다. Such deodorant imports using tank lorry are suitable for facilities that import large quantities of about 1,000 to 10,000 liters at a time. The scale of small- and medium-sized LNG supply facilities with 10-300 liters of deodorant storage now or in the future is not appropriate. For this purpose, the deodorant is collected in a suitable container (for example, 18 liter plastic container, etc.). Since funnels, etc., must be installed and injected into the storage containers, they may pose a significant hazard due to the scattering or spillage of the odorant as well as the severe odor or the use of an uneconomic method using tank lorry.

따라서, 본 발명은 상기와 같은 문제를 감안하여 안출한 것으로서, 소량 부취제의 운반및 이.충전시 안전을 확보하기 위해 정형화된 강제 용기에 부취제의 이, 충전에 필요한 밸브와 액면계를 설치하고 주입용 호스를 설치하여 경제적이고 안전하며 용이한 이. 충전 작업을 수행 할 수 있도록 부취제 주입장치를 제공하는데 그 안출의 목적이 있다. Accordingly, the present invention has been made in view of the above problems, and in order to ensure safety during transportation and filling of small amounts of odorant, a valve and a liquid level meter required for transferring or filling the odorant are provided in a standard forced container. Economical, safe and easy to install with injection hose. Its purpose is to provide a deodorant injector so that filling can be performed.

이하, 상기와 같은 목적을 달성하기 위한 본 발명의 특징에 대해 설명하면 다음과 같다.Hereinafter, the features of the present invention for achieving the above object are as follows.

On the deodorant storage container 100, a pressure equalizing valve 420, a booster valve 430, and a pressure gauge 510 are mounted. Provide convenience for charging.

여기서 부취제 저장용기(100)는 반드시 내식성 재료인 스테인리스 스틸을 사용하여 부취제의 강한 부식성에 견딜 수 있도록 해야 할 것이며, 또한 모든 강제품역시 스테인리스 스틸을 사용하여야 할 것이다. 또한, 부취제의 강한 화학성에 견딜 수 있도록 액면계(520)용 튜브는 플라스틱제품을 사용하여야 한다.Here, the odorant storage container 100 must be able to withstand the strong corrosiveness of the odorant by using stainless steel, which is a corrosion resistant material, and all steel products must also use stainless steel. In addition, the tube for the liquid level gauge 520 should use a plastic product to withstand the strong chemical properties of the odorant.

이하 본 발명의 바람직한 실시 예를 첨부한 도면에 의거 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

도3은 본 발명에 따른 도2를 본 용도에 맞는 사용처에 장착한 것을 도시한 것으로서 부취제 주입용 호스(21a)를 본 발명에 속한 균압용 밸브(420)의 호스노즐(340)과 부취제 저장용기(13a)의 균압밸브(61)에, 균압용 호스(22a)를 본 발명에 속한 충전용 밸브(410)의 호스노즐(330)과 부취제 저장용기(13a)의 충전밸브(62)에 각각 취부하고 밴드 등으로 단단히 고정하여 부취제 저장용기(13a)보다 상부 에 위치토록 하여 위치에너지를 크게 하는 것이 중요하다.3 is a view illustrating the installation of FIG. 2 according to the present invention at a place suitable for the purpose of the present invention, and the hose nozzle 340 and the odorant of the equalizing valve 420 of the odorant injection hose 21a according to the present invention. The pressure equalizing valve 61 of the storage container 13a, the pressure equalizing hose 22a, the hose nozzle 330 of the filling valve 410 of the present invention, and the filling valve 62 of the odor storage container 13a. It is important to increase the potential energy by attaching them to each other and fixing them firmly with a band or the like so as to be located above the odorant storage container 13a.

유량계(520)상의 부유물및 침전물 등의 유무를 점검하여 충전용 밸브(410) 후단에 라인필터의 설치여부를 판단하여야 한다.The presence or absence of suspended matter and sediment on the flow meter 520 should be checked to determine whether the line filter is installed at the rear end of the filling valve 410.

부취제 주입을 위해 먼저 균압밸브(61)와 본 발명에 따른 균압밸브(420)를 서서히 열어 양측의 압력을 동일하게 하고, 충전용 밸브(62)와 본 발명에 따른 충전용 밸브(410)를 서서히 열어 부취제 충전을 개시한다. 이때 유량계(520)와 저장용기(13a)의 유량계를 확인하고 충전밸브(410)와 균압밸브(420)를 이용하여 충전속도를 조정한다.For injection of the odorant, first, the pressure equalizing valve 61 and the pressure equalizing valve 420 according to the present invention are gradually opened to equalize the pressure on both sides, and the filling valve 62 and the filling valve 410 according to the present invention are opened. Open slowly and start odor filling. At this time, the flow meter of the flow meter 520 and the storage container 13a is checked and the filling speed is adjusted using the filling valve 410 and the equalizing valve 420.

충전밸브(410) 후단에 라인필터를 설치하여 유속에 저항이 발생하거나 위치에 따른 차압이 크지 않아 충전속도가 길어질 경우 별도로 준비된 질소용기(600)에 압력조정밸브(610)와 본 발명에 따른 증압용 밸브(430)에 적당한 길이의 증압호스(340)를 설치하고 부취제 저장용기(100)의 기상부를 서서히 가압하여 충전속도를 조정할 수 있다. 이때 가압되는 압력을 확인하기 위하여 압력계(510)를 주시하여야 하며 가압되는 압력은 0.5MPa 이하로 하고, 안전을 확보하기 위하여 증압밸브(610)는 ON/OFF방식의 스톱밸브가 아닌 압력조정밸브(Regulator)와 스톱밸브를 병행 사용하여야 할 것이다. When the line filter is installed at the rear end of the filling valve 410 so that the filling speed is long due to the resistance of the flow rate or the differential pressure depending on the position, the pressure adjusting valve 610 and the increase according to the present invention are increased. The pressure increase hose 340 of the appropriate length is installed in the pressure valve 430, and the filling rate can be adjusted by gradually pressurizing the gas phase of the odor storage container 100.
