유조선의 화물보전장치Oil tanker cargo preservation device

첨부도면은 본 발명에 관한 유조선의 화물보전장치를 표시한 배치계통도.The accompanying drawings are a batch system showing the cargo holding device of the tanker according to the present invention.

본 발명의 유류의 하역 및 수송중에 생기는 유류가스의 입력변화를 조절하고 또한 유류가스의 선외에의 방출을 방지함과 동시에 탱크 내에의 공기유입을 방지하도록 한 유조선의 화물보전장치에 관한 것이다.The present invention relates to a cargo preservation apparatus for an oil tanker, which controls an input change of oil gas generated during unloading and transportation of oil, and prevents the outflow of oil gas to the outboard and at the same time, prevents the inflow of air into the tank.

이하 첨부도면에 표시되어 있는 일실시예에 의해 본 발명을 더욱 상세히 설명하면, 선체의 일부를 이루는 화물적재탱크(1)에는 유류(2)가 적재되어 있으며, 그 상부공간은 유류가스(3)가 충만되어 있어서, 각 화물적재탱크(1)의 정상부에는 가스흡입지관(4)이 각 착설되어 있으며, 이들의 지관은 가스흡입주관(5)에 접속되어 있다. 가스흡입주관(5)은 압축기(6) 및 냉각기(7)를 거쳐 가열기(8)를 내장하는 압력용기(9)에 인도되어, 이 압력용기에는 가스토출밸브(10)를 가진 가스토출주관(11)이 착설되어 있으며, 이 주관은 가스토출지관(12)을 거쳐서 각 화물적재탱크(1)에 인되되어 있다. 화물적재탱크(1)에는 압력검출기(13)가 착설되어 있으며, 이 압력검출기에 결합된 신호 발신기(14)와 압축기(6) 및 가스토출밸브(10)는 각각 신호전송 라인에 의해서 연결되어 있다. 압력용기(9)에는 수입구(16)가 형성되어 있으며, 선외에서 유가스(3)를, 상기 용기에 꺼내고 넣는 것도 가능한 것이다.Hereinafter, the present invention will be described in more detail with reference to one embodiment shown in the accompanying drawings, in which a cargo tank 1 forming part of the hull is loaded with oil 2, and the upper space of the oil gas 3 The gas suction branch pipes 4 are installed at the top of each cargo loading tank 1, and these branch pipes are connected to the gas suction main pipes 5, respectively. The gas suction pipe 5 is led to a pressure vessel 9 having a heater 8 therein via a compressor 6 and a cooler 7, which has a gas discharge valve having a gas discharge valve 10. 11) is installed, and the main pipe is attached to each cargo tank 1 via the gas discharge branch 12. A pressure detector 13 is installed in the cargo loading tank 1, and the signal transmitter 14, the compressor 6, and the gas discharge valve 10 coupled to the pressure detector are connected by signal transmission lines, respectively. . The inlet port 16 is formed in the pressure container 9, and it is also possible to take out the oil gas 3 to the said container outside the ship.

그래서, 상기 구성을 갖는 본 발명 장치의 작용을 설명하면 다음과 같다.Thus, the operation of the apparatus of the present invention having the above configuration will be described.

선외에서 화물적재탱크(1)에 유류(2)가 적재하면, 이 유류의 액면이 상승하므로, 유류가스(3)의 압력이 상승하여 이 압력은 압력검출기(13)에 의해 검출되고, 미리 설정된 압력이상이 되면, 신호발신기(14)가 신호를 내보내고, 이 신호는 신호전송라인(15)에 의해서 압축기(6)에 전달되고, 이 압축기를 시동시킨다. 따라서, 유류가스(3)는 가스흡입지관(4) 및 가스흡입주관(5)을 거쳐서 압축기(6)에 흡입되어서 가압압축된 후, 냉각기(7)를 거쳐서 압력용기(9)에 가압된 가스 또는 액화가스의 형태로 저장된다. 이 때, 압축된 가스가 고온이면 냉각기(7)에 의해서 냉각된다. 이와 같이 하여, 유류가스(3)가 압력용기(9)에 옮겨지고, 이 유류가스의 압력이 저하되어, 미리 설정된 압축기(6)의 정지압력 이하가 되면, 신호발신기(14)가 신호를 내보내어, 압축기(6)는 정지한다.When the oil 2 is loaded in the cargo tank 1 onboard, the liquid level of the oil rises, so the pressure of the oil gas 3 rises and this pressure is detected by the pressure detector 13, When the pressure is over, the signal generator 14 sends out a signal, which is transmitted to the compressor 6 by the signal transmission line 15, and starts the compressor. Therefore, the oil gas 3 is sucked into the compressor 6 through the gas suction branch pipe 4 and the gas suction main pipe 5, and is pressurized and compressed, and then pressurized by the pressure vessel 9 through the cooler 7. Or in the form of liquefied gas. At this time, if the compressed gas is a high temperature, it is cooled by the cooler 7. In this way, when the oil gas 3 is transferred to the pressure vessel 9, and the pressure of this oil gas falls and it becomes below the preset pressure of the compressor 6, the signal transmitter 14 will signal. The compressor 6 is stopped.

다음에, 선의에 화물적재탱크(1)에서 유류(2)가 양륙되면, 이 유류의 액면이 하강해서 유류가스(3)의 압력이 저하한다. 이 압력검출기(13)에 의해 검출되고, 미리 설정된 압력이하가 되면, 신호발신기(14)에 전달되어, 가스토출밸브(10)를 개방한다. 이 때문에 압력용기(9)에, 저장되어 있던 가스는, 가스토출주관(11) 및 가스토출지관(12)를 거쳐서 화물적재탱크(1)에 방출된다. 이때, 필요에 따라서 가열기(8)에 의해 액화가스를 가열하고, 가스의 증발을 촉진한다. 이렇게 해서, 압력용기(9)의 가스가 화물적재탱크(1)에 옮겨져서, 유류가스(3)의 압력이 상승하고, 미리 설정된 가스토출밸브(10)의 폐쇄압력 이상이 되면, 신호발신기(14)가 신호를 내보내서, 가스토출밸브(10)가 폐쇄된다. 이와같이 하여, 화물적재탱크(1)의 압력은 미리 설정된 압력범위내에 유지된다.Next, when the oil 2 is unloaded from the cargo loading tank 1 in good faith, the liquid level of this oil falls and the pressure of the oil gas 3 falls. When detected by the pressure detector 13 and below a predetermined pressure, the pressure detector 13 transmits the signal to the signal generator 14 to open the gas discharge valve 10. For this reason, the gas stored in the pressure container 9 is discharged | emitted to the cargo loading tank 1 through the gas discharge discharge pipe 11 and the gas discharge discharge pipe 12. As shown in FIG. At this time, the liquefied gas is heated by the heater 8 as needed, and the evaporation of the gas is promoted. In this way, when the gas of the pressure container 9 is transferred to the cargo loading tank 1, the pressure of the oil gas 3 rises and it becomes more than the closing pressure of the preset gas discharge valve 10, a signal transmitter ( 14 outputs a signal, so that the gas discharge valve 10 is closed. In this way, the pressure of the cargo loading tank 1 is kept within the preset pressure range.

또 선박이 항행 내지 정박시는 선박의 동요, 온도변화 등에 의해 유류(2)가 증발 내지 응축하므로, 유류가스(3)의 압력은 끊임없이 변동하지만, 이 경우도 전술한 하역시의 순서와 마찬가지로 해서 화물적재탱크(1)의 압력은 설정압력 범위내에 유지된다.In addition, since the oil 2 evaporates or condenses when the vessel is sailing or anchoring, the pressure of the oil gas 3 is constantly changing. In this case, The pressure in the cargo loading tank 1 is kept within the set pressure range.

또한, 압력용기는 필요에 따라서 선외와의 사이에서 수입구(16)를 통하여 유류가스 또는 액화가스를 지원받는 것도 가능하다.In addition, the pressure vessel may be supported by the oil gas or liquefied gas through the import port 16 between the outboard and, if necessary.

이상 설명한 바와 같이, 본 발명에 관한 화물보전장치는, 유류가스 및 유류를 수용하고 있는 압력검출기가 착설되어 있는 각 화물적재탱크의 상부에 설치한 가스흡입지관을 압축기 및 냉각기를 거쳐서 가열기를 내장하고 있는 유류가스 저장용 압력용기에 접속하고, 또한 이 압력용기에 가스토출밸브를 가진 가스토출주관을 거쳐서 상기 각 화물적재탱크에 인도되어 있는 가스토출지관을 접속하고, 또한 상기 압력검출기와 압축기 및 가스토출밸브를 신호전송라인에서 결합하므로서 상기 유류의 하역 및 수송중에 생기는 유류 가스의 압력변화를 조절함과 동시에 상기 화물적재탱크와 외기를 완전히 차단하도록 구성하였으므로, 화물탱크는 대기와 완전히 차단되어, 이것으로 화물의 감손이 없고, 공기의 혼입에 의한 폭발혼합기가 형성되는 우려가 없는 위에 탱크내에서 산소가 존재하지 않으므로 탱크의 부식이 방지되는 등의 효과가 있으며, 또 압축기는 고압력을 얻을 필요가 없기 때문에 LPG선의 재액화 장치에 비해서 장치의 생산가는 훨씬 염가로 되며, 따라서 화물을 안전하게 경제적으로 또한 용이하게 보전, 운반할 수가 있는 것이다.As described above, the cargo preservation apparatus according to the present invention includes a gas intake pipe installed in the upper portion of each cargo loading tank in which oil gas and a pressure detector containing oil are installed, and a heater is built in through a compressor and a cooler. Connected to a pressure vessel for storing oil gas, which is connected to a gas discharge branch leading to each of the cargo loading tanks through a gas discharge main line having a gas discharge valve, and further comprising the pressure detector, the compressor and the gas. By combining the discharge valve in the signal transmission line to control the pressure change of the oil gas generated during the loading and unloading of the oil and at the same time completely shut off the cargo tank and the outside air, the cargo tank is completely blocked from the atmosphere, There is no loss of cargo and there is a risk of explosion Since there is no oxygen in the tank above, the corrosion of the tank is prevented. Also, since the compressor does not need to obtain a high pressure, the production cost of the device is much cheaper than that of the LPG ship reliquefaction device. It can be safely and economically and easily preserved and transported.
