Description

유조선의 원유 슬러지 퇴적 방지장치{A crude petroleum seulluji accumulation protect device of the gasoline tanker}A crude petroleum seulluji accumulation protect device of the gasoline tanker}

본 고안은 유조선의 원유 슬러지 퇴적 방지장치에 관한 것으로, 보다 상세하게는 원유를 수송하는 유조선의 원유저장탱크의 일측에 복수 개의 초음파발생부를 설치하여 원유저장탱크의 내주면에 다량의 원유 슬러지가 침전되지 못하도록 한 유조선의 원유 슬러지 퇴적 방지장치에 관한 것이다.The present invention relates to an oil tanker sludge deposition prevention device, and more particularly, a plurality of ultrasonic generators are installed on one side of the oil storage tank of the oil tanker transporting crude oil so that a large amount of oil sludge does not settle on the inner circumferential surface of the oil storage tank. The present invention relates to a crude oil sludge deposition preventing device of an oil tanker.

일반적으로, 유조선(油槽船, oil-tanker)은 석유류·경유(鯨油)·당밀(糖蜜)·포도주원액·화공약품 및 액화석유가스(LPG)·액화천연가스(LNG) 등 액체화물을 용기에 넣지 않은 비포장 상태로 산적(散積)하여 대량수송하는 선박이다.In general, oil-tankers contain liquid cargo such as petroleum, diesel, molasses, wine liquor, chemicals, and liquefied petroleum gas (LPG) and liquefied natural gas (LNG). It is a ship that carries out bulk transportation in unpacked unpacked state.

그리고, 유송선(油送船)·탱크 또는 오일탱크라고도 한다. 이들 운송화물 중에서 대종을 이루는 것은 석유류로서, 중동 북아프리카·중남아메리카·북아메리카·동남아시아 등지에서 정유시설지(精油施設地)로 수송되는 원유와 정유지에서 소비지로 수송되는 정제유(精製油)이다. 근래에 와서는 LPG 탱크도 많이 나타나고 있다. 유조선은 일반화물선과는 달리 보통 만재(滿載) 상태로 수송하고, 양하지(揚荷地)에서 선적지로 되돌아갈 때는 공선(空船) 상태로 항해하면서 화물유 탱크를 씻는 작업(tank cleaning)을 한다.Moreover, it is also called a transfer ship tank, an oil tank. Among these cargoes, petroleum is mainly used as crude oil which is transported from the Middle East, North Africa, Central and South America, North America, and Southeast Asia to refinery sites and refined oil transported from the refinery to consumption. Recently, many LPG tanks have appeared. Oil tankers, unlike ordinary cargo ships, are usually transported in full load, and when they return to the place of shipment from the offshore, they carry out tank cleaning while navigating in an empty ship. do.

특히, 수송하는 화물에 따라 원유탱크·정제유탱크·LPG탱크·LNG탱크·케미컬탱크등으로 분류되고, 운항해역에 따라 내항 탱크와 외항 탱크로 분류한다. 내항 탱크는 정제유 및 화공약품의 연안수송에 사용되는 수백 t급의 작은 탱크가 많고, 외항 탱크는 원산지에서 소비지로 수송되는 원유·정제유 등을 대량으로 실어 나르는 탱크로서 그 크기는 수천 t급에서 수십만 t급에 이른다. 또한 탱크는 크기에 따라 매머드탱크(mammoth tanker:1950년대 미국이 석유수출국에서 수입국으로 정책을 전환함에 따라 석유의 해상수송량은 급증하였는데, 이 때 출현한 대형 탱크로서 4만 5000dwt급이다), 슈퍼탱크(super tanker:1940년대 말기에는 당시 초대형급인 2만 4000dwt급의 탱크를 가리키는 말이었으나, 오늘날에는 보통 유조선보다 훨씬 큰 초대형 탱크를 지칭하는 말로 사용되며, 보통 VLCC보다는 작은 탱크를 말한다), VLCC(very large crude oil carrier:슈퍼탱크로서, 특히 25만 dwt 이상의 탱크이며 ULCC보다 작은 것을 가리킨다), ULCC(ultra large crude oil carrier:VLCC보다 큰 것으로서 35만 dwt 이상의 것을 말한다) 등으로 불리고, 수송화물의 청결도에 따라 원유나 중유를 수송하는 더티탱크(dirty tanker)와 가솔린·경유 등을 수송하는 클린탱크(clean tanker)로 구분한다.In particular, they are classified into crude oil tanks, refined oil tanks, LPG tanks, LNG tanks, and chemical tanks according to the cargo to be transported. Inner tanks contain many hundreds of t-sized small tanks used for coastal transportation of refined oils and chemicals, while outer tanks carry large quantities of crude oil and refined oils transported from the origin to the consumer. It reaches t grade. Also, the size of the tanks increased by the size of the mammoth tanker (1950's US policy shifted from an oil exporter to an importer). (super tanker: At the end of the 1940s, it was the term super large tank of 24,000dwt, but today it is usually used to refer to a very large tank that is much larger than an oil tanker, usually a tank smaller than VLCC), VLCC (very Large crude oil carrier: Super tank, especially 250,000 dwt tank or more, smaller than ULCC), ULCC (ultra large crude oil carrier: larger than VLCC, 350,000 dwt or more), etc. According to the classification, it is divided into a dirty tanker for transporting crude oil or heavy oil and a clean tanker for transporting gasoline and diesel.

도 1은 일반적인 유조선을 나타낸 도면이다.1 is a view showing a general tanker.

도 1에 도시된 바와 같이, 유조선은 선체(Side shell plate)(10)와, 상기 선체(10)를 수상에서 이동시킬 수 있도록 동력을 발생하는 기관실(도시는 생략함)과, 상기 기관실로 연료를 공급하는 연료탱크(도시는 생략함)와, 원유를 저장하는 원유저장탱크(12)와, 상기 선체(10)의 이동을 제어하는 운전실(14) 등을 포함하여 구성된다.As shown in FIG. 1, an oil tanker includes a side shell plate 10, an engine room (not shown) that generates power to move the hull 10 in the water phase, and fuel to the engine room. And a fuel tank (not shown) for supplying oil, a crude oil storage tank 12 for storing crude oil, and a cab 14 for controlling the movement of the hull 10.

여기서, 상기 유조선의 원유저장탱크(12)는 환경오염을 고려한 이중선체구조(Double hull)이 의무화되면서 화물창의 구조가 직육면체에 가까운 형태를 취하고 있다.Here, the crude oil storage tank 12 of the tanker is a mandatory double hull structure (Double hull) in consideration of environmental pollution is taking the structure of the cargo hold close to the rectangular parallelepiped.

그러나, 상기와 같이 유조선의 원유저장탱크가 이중선체구조라 하더라도 원유의 산지와 선박의 운항 일수에 따라, 도 2에 도시된 바와 같이 원유저장탱크의 내부에 원유 슬러지(16)가 최대 25㎝ ∼ 30㎝까지 쌓이는 문제점이 있었다.However, even if the oil storage tank of the tanker is a double hull structure as described above, depending on the origin of the crude oil and the number of days of operation of the vessel, as shown in Figure 2, the crude oil sludge (16) up to 25 cm ~ 30 inside the crude oil storage tank There was a problem of accumulating up to cm.

상기 원유 슬러지를 제거 하기 위해, 하역시 메인 배관에 별도의 브랜치 라인(Branch Line)을 설치하여 빼낸 원유를 고압의 피드 백 시스템에 의해 다시 화물창으로 슈팅(Shooting)을 하여 퇴적된 슬러지를 제거해야 하는 번거로움이 있었다.In order to remove the crude oil sludge, a separate branch line is installed in the main pipe during unloading to remove the sludge deposited by shooting with the high pressure feed back system to the cargo hold. There was a hassle.

이로 인해, 하역되는 원유의 일부를 피드 백시키는 크루드 오일 와싱(Crude oil washing) 시스템은 선박 건조시 건조 선가를 상승시킬 뿐만 아니라 원유의 하역 시간이 길어지는 문제점이 있다.As a result, the crude oil washing system for feeding back a portion of the unloaded crude oil has a problem in that the shipbuilding time of the crude oil is increased as well as the drying cost is increased during ship construction.

또한, 크루드 오일 와싱 이후에도 상당량의 원유 슬러지가 탱크 내부에 상존하여 잔여 부분에 대해서는 선원들이 일일이 청소를 해야 하는 문제점이 있었다.In addition, even after the crude oil washer, a large amount of crude sludge remained inside the tank, and there was a problem that the crews had to clean the remaining portions.

따라서, 본 고안은 상기한 종래 기술에 따른 제반 문제점을 해결하기 위하여 제안된 것으로서, 본 고안의 목적은 원유를 수송하는 유조선의 원유저장탱크의 일측에 복수 개의 초음파발생부를 설치하여 원유저장탱크의 내주면에 다량의 원유 슬러지가 침전되지 못하도록 한 유조선의 원유 슬러지 퇴적 방지장치를 제공하는데 있다.Therefore, the present invention has been proposed to solve the above problems according to the prior art, an object of the present invention is to install a plurality of ultrasonic generators on one side of the crude oil storage tank of the tanker transporting crude oil to the inner peripheral surface of the crude oil storage tank It is to provide a crude oil sludge deposition prevention device for oil tankers that prevents a large amount of crude oil sludge from settling.

It is composed of an ultrasonic generator 500 for generating ultrasonic waves 15 ~ 20 kHz or more to the inner peripheral surface of the.

상기 초음파발생부(500)는, 원유 저장탱크(12)의 내주면에 원유 슬러지가 부착되지 않도록 상기 원유 저장탱크(12)의 내주면으로 15㎑ ∼ 20㎑ 이상의 초음파를 발생하는 것으로, 원유 저장탱크(12)의 일측면에 9㎡ 당 한 개씩 설치되는 것이 좋다.The ultrasonic generator 500 generates an ultrasonic wave of 15 kPa to 20 kPa or more to the inner circumferential surface of the crude oil storage tank 12 so that crude oil sludge does not adhere to the inner circumferential surface of the crude oil storage tank 12. It is better to install one per 9㎡ on one side of 12).

여기서, 상기 초음파는 가청주파보다 높고, 대체로 15㎑ ∼ 20㎑ 이상의 음파를 말하는데, 기름이나 먼지 따위가 묻은 것을 액체 속에 담근 다음 액체에 초음파를 가하면 액체의 압력이 충격적으로 변동하고, 그 표면이 침식되어 세척이 된다.Here, the ultrasonic wave is higher than the audible frequency, and generally refers to sound waves of 15 ㎑ to 20 ㎑ or more. When soaking oil or dust in a liquid and then applying ultrasonic wave to the liquid, the pressure of the liquid fluctuates shock and the surface is eroded. It is washed.

이와 같이 구성된 유조선의 원유 슬러지 퇴적 방지장치의 설치과정 및 동작을 도 5를 참조하여 설명하면 다음과 같다.Referring to Figure 5 the installation process and operation of the crude oil sludge deposition prevention device of the tanker configured as described above are as follows.

먼저, 원유 저장탱크(12)의 일측면 9㎡ 당 한 개씩 15㎑ ∼ 20㎑ 이상의 초음파를 발생하는 초음파발생부(500)를 설치한다.First, an ultrasonic generator 500 for generating ultrasonic waves of 15 kHz to 20 kHz or more per one 9m2 of one side of the crude oil storage tank 12 is installed.

그리고, 상기 초음파발생부(500)를 운전실(14)의 제어부(200)와 전기적으로 연결시킨다.The ultrasonic generator 500 is electrically connected to the controller 200 of the cab 14.

그런후에, 사용자는 운전실(14)의 내부에 설치된 키(key)를 조작하여 전원공급부(100)로 전원을 공급한다. Thereafter, the user operates a key installed in the cab 14 to supply power to the power supply unit 100.

이때, 상기 전원공급부(100)는 제어부(200)로 구동전원을 공급한다.In this case, the power supply unit 100 supplies driving power to the control unit 200.

한편, 상기 제어부(200)는 발진부(300)로 발진신호를 보낸다.On the other hand, the control unit 200 sends an oscillation signal to the oscillator 300.

그리고, 상기 발진기(300)는 발진을 시작하고, 발진신호를 분배기(400)를 통해 초음파발생부(500)로 보낸다.The oscillator 300 starts oscillation and sends an oscillation signal to the ultrasonic generator 500 through the distributor 400.

따라서, 상기 초음파발생부(500)는 분배기(400)로부터 발진신호를 인가받고, 원유 저장탱크(12)의 내부면으로 15㎑ ∼ 20㎑ 이상의 초음파를 발생한다.Accordingly, the ultrasonic generator 500 receives the oscillation signal from the distributor 400 and generates ultrasonic waves of 15 kV to 20 kV or more to the inner surface of the crude oil storage tank 12.

이때, 원유 저장탱크(12)의 내주면으로 송출된 초음파는 충격적으로 변동되고, 원유 저장탱크(12)의 내부면으로 원유 슬러지가 부착되지 않도록 한다.At this time, the ultrasonic wave sent to the inner circumferential surface of the crude oil storage tank 12 is shock-changing, so that the crude oil sludge does not adhere to the inner surface of the crude oil storage tank 12.

이상에서 상술한 바와 같이 본 고안은 원유 저장탱크의 내주면으로 초음파를 발생시켜 캐비테이션 효과를 유발하여 원유 저장탱크에 부착되는 슬러지의 응집력을 떨어뜨리는 현상이 발생하여 원유 슬러지의 퇴적을 원천적으로 방지하는 효과가 있다.As described above, the present invention generates an ultrasonic wave to the inner circumferential surface of the crude oil storage tank to cause a cavitation effect, thereby reducing the cohesion of the sludge adhered to the crude oil storage tank, thereby preventing the deposition of the crude oil sludge. There is.

그리고, 본 고안은 원유 슬러지의 퇴적이 원천적으로 상쇄되면서 기존 하역시 채택되어 왔던 크루드 오일 와싱 단계가 생략되면서 하역시간이 단축되는 효과가 있다.In addition, the present invention has the effect of shortening the unloading time by eliminating the crude oil washer step has been adopted at the time of unloading as the sedimentation of the crude sludge is omitted.

하역시간 단축에 따른, 체선료 등 선사의 제반비용이 절감되는 효과가 있다.According to the shortening of the unloading time, all costs of shipping companies such as a ship fee are reduced.

특히, 본 고안은 기존 선박에서 원유 슬러지의 잔여부분 제거를 위해 수작업을 해왔던 공정이 없어지면서 인사사고를 미연에 방지할 있고, 선원들의 작업환경도 크게 개선할 수 있는 효과가 있다.In particular, the present invention prevents personnel accidents in advance as the process of manual work is removed for the removal of the remaining portion of crude oil sludge in the existing vessel, and the working environment of the crew can be greatly improved.
