Description

원유탱크 청소 시스템Crude oil tank cleaning system
본 발명은 원유탱크 청소 시스템에 관한 것으로서, 보다 상세하게는 원유탱크 내에 세척수와 스팀 및 에어를 고압 분사하여 원유탱크의 바닥에 쌓여 있는 고체화된 슬러지(sludge)를 용이하게 제거할 수 있는 원유탱크 청소 시스템에 관한 것이다.The present invention relates to a crude oil tank cleaning system, and more specifically, to a crude oil tank cleaning system that can easily remove solidified sludge accumulated on the bottom of a crude oil tank by spraying high-pressure washing water, steam, and air into the crude oil tank. It's about the system.
지하에서 끌어올린 원유는 유조선에 실리기 전과 정제를 위해 정제시설로 투입되기 전에 원유탱크에 임시로 저장된다.Crude oil pulled from underground is temporarily stored in crude oil tanks before being loaded on oil tankers and before being injected into refinery facilities for refining.
원유탱크에 원유의 유입과 유출이 반복되면 원유탱크의 바닥에는 슬러지가 쌓이면서 고착화된다.When the inflow and outflow of crude oil into a crude oil tank is repeated, sludge accumulates and solidifies at the bottom of the crude oil tank.
고착화되어 쌓이는 슬러지의 양이 증가하면 원유탱크의 저장용량이 줄어들게 되어 어느 시점에서는 원유탱크에서 슬러지를 제거하는 정제작업을 해야한다.As the amount of solidified and accumulated sludge increases, the storage capacity of the crude oil tank decreases, and at some point, refining work to remove sludge from the crude oil tank is required.
보통 수년이 경과하여 슬러지가 1-2m 쌓이고 이때는 정제작업이 필요하다.Usually, after several years, 1-2m of sludge accumulates, and at this time, purification work is required.
원유탱크에 고착화되어 쌓인 슬러지를 제거하는 원유탱크 세정장치에 관한 종래기술로는 등록특허 제10-1224010호 "원유저장탱크 자동 세척장치", 등록특허 제10-0475172호 "원유탱크 내의 슬러지 제거 및 오일유분의 회수방법" 등이 개시되었다.Conventional technologies related to crude oil tank cleaning devices that remove sludge stuck and accumulated in crude oil tanks include Patent No. 10-1224010, “Automatic Cleaning Device for Crude Oil Storage Tanks,” and Patent No. 10-0475172, “Removal of Sludge in Crude Oil Tanks and “Method for recovering oil fractions” etc. were disclosed.
상기 등록특허 제10-1224010호와 제10-0475172호를 포함하는 종래기술에서는 원유탱크 내에 고온의 열매체유를 투입하여 고착화된 슬러지가 용융되도록 한 후에 열매체유와 용융된 슬러지의 혼합물을 펌프를 이용해 원유탱크 외부로 배출시키고, 펌프로 배출시킬 수 없는 원유탱크 바닥에 깔린 혼합물은 작업자가 마스크를 쓰고 들어가 수작업으로 제거하는 방식으로 원유탱크를 세정한다.In the prior art, including Patent Nos. 10-1224010 and 10-0475172, high-temperature heat transfer oil is added into a crude oil tank to melt the stuck sludge, and then a mixture of heat transfer oil and melted sludge is pumped. The crude oil tank is cleaned by discharging it to the outside of the crude oil tank, and removing the mixture on the bottom of the crude oil tank that cannot be pumped out by a worker wearing a mask and removing it manually.
물질의 보통 유사한 성분의 물질에 보다 쉽게 용융되는 성질이 있어서, 종래기술에서는 오일성분의 슬러지를 오일성분의 열매체유를 이용하여 용융시킨다.Since substances of similar composition usually have the property of melting more easily, in the prior art, oil-based sludge is melted using oil-based heat medium oil.
그런데, 종래기술에서 열매체유를 이용한 슬러지의 용융이 그리 빠르지 않다. 초기에 투입된 열매체유는 고온이어서 슬러지의 용융속도가 비교적 빠르나 시간이 지나면서 열매체유의 온도가 낮아져 용융속도가 느려지고, 자연 용융은 별론으로 하고 열매체유를 휘젖는 것 이외에는 용융속도를 높이는 다른 요인이 없어 슬러지의 용융에 많은 시간이 소요된다.However, in the prior art, melting of sludge using heat medium oil is not very fast. Initially, the heat medium oil introduced is at a high temperature, so the melting speed of the sludge is relatively fast, but over time, the temperature of the heat medium oil decreases and the melting speed slows down. There is no other factor that increases the melting speed other than stirring the heat medium oil, let alone natural melting. It takes a lot of time to melt the sludge.
그래서, 직경이 수십미터에 이르는 대형 원유탱크 수십 개가 모여 있는 단지내의 원유탱크들을 모두 세정하는데 적게는 수개월에서 길게는 1년 이상이 소요된다.Therefore, it takes from several months to more than a year to clean all the crude oil tanks in a complex where dozens of large crude oil tanks with diameters of tens of meters are gathered.
그리고, 종래기술에서는 펌프로 배출시킬 수 없는 원유탱크의 바닥에 남은 슬러지 찌거기는 작업자가 원유탱크 내부로 들어가 수작업으로 제거를 하게 되는데, 원유탱크 내부는 유해성분으로 꽉차 있어서 작업자는 산소 마스크를 필수로 착용하고 들어가야 하고, 산소 마스크를 착용하더라도 안전을 보장할 수 없어 인명사고가 종종 발생한다.In addition, in the prior art, the sludge residue remaining at the bottom of the crude oil tank, which cannot be discharged by a pump, has to be removed manually by workers entering the crude oil tank. The inside of the crude oil tank is full of harmful ingredients, so workers are required to wear oxygen masks. You have to wear an oxygen mask to enter, and even if you wear an oxygen mask, safety cannot be guaranteed, so fatal accidents often occur.
본 발명은 상기와 같은 종래기술의 제반 문제점을 해소하기 위하여 안출된 것으로서, 본 발명의 기술적 구성에 의한 목적은 원유탱크 내에 세척수와 스팀 및 에어를 고압 분사하여 원유탱크의 바닥에 쌓여 있는 고체화된 슬러지(sludge)를 용이하게 제거할 수 있는 원유탱크 청소 시스템을 제공하는데 있다.The present invention was developed to solve all the problems of the prior art as described above, and the purpose of the technical structure of the present invention is to spray high-pressure washing water, steam, and air into the crude oil tank to remove solidified sludge accumulated at the bottom of the crude oil tank. The goal is to provide a crude oil tank cleaning system that can easily remove sludge.

It is detachably coupled to the part, and at one end is formed a female thread to be screwed to the male thread of the fixing flange, and at the other end may include a connecting member having a flange portion connected to the distributor.
또한, 분사노즐은 상기 플로팅루프의 하부에 방사상으로 복수 개 배치되며, 상기 분사노즐의 하단부는 분사되는 세척수가 와류현상을 일으켜 플로팅루프의 중심으로 슬러지가 모이도록 하향으로 경사지게 형성될 수 있다.In addition, a plurality of spray nozzles are radially disposed at the bottom of the floating loop, and the lower ends of the spray nozzles may be inclined downward so that the sprayed washing water generates a vortex phenomenon and causes sludge to collect at the center of the floating loop.
또한, 슬러지 배출수단은 상기 원유탱크 내부에 세척수가 채워짐에 따라 세척수 위로 부상하는 슬러지를 흡입하는 복수 개의 제1 흡입펌프와, 상기 원유탱크 바닥에 잔류하는 슬러지와 폐수를 흡입하는 복수 개의 제2 흡입펌프를 포함할 수 있다.In addition, the sludge discharge means includes a plurality of first suction pumps that suction the sludge that floats on the wash water as the inside of the crude oil tank is filled with the wash water, and a plurality of second suction pumps that suction the sludge and wastewater remaining at the bottom of the crude oil tank. May include a pump.
또한, 플로팅루프의 하단에는 원유탱크 내에 채워진 물속에 슬러지를 영상으로 확인할 수 있도록 복수 개의 영상탐지센서가 구비될 수 있다.In addition, a plurality of image detection sensors may be provided at the bottom of the floating loop so that sludge in the water filled in the crude oil tank can be confirmed through images.
또한, 원유탱크의 하부의 일측 상부와 하부에는 유수분리조와 연결되어 펌프를 통해 공급되는 세척수를 분사시키는 상부 슬러지 배출노즐과 하부 슬러지 배출노즐이 각각 구비되며, 상기 원유탱크의 하부의 타측 상부와 하부에는 슬러지와 폐수가 배출되는 슬러지 배출구와 폐수 배출구가 각각 형성될 수 있다.In addition, the upper and lower sides of the lower part of the crude oil tank are respectively equipped with an upper and lower sludge discharge nozzles that are connected to the oil-water separation tank and spray washing water supplied through a pump, and the upper and lower parts of the other side of the lower part of the crude oil tank.

본 발명에 따르면, 루프레그를 통하여 세척수, 스팀, 고압을 분사시킴으로써 원유탱크의 바닥면에 고착된 슬러지를 잘게 부수어 신속하게 부상시켜 제거할 수 있다.According to the present invention, by spraying washing water, steam, and high pressure through the roof leg, the sludge stuck to the bottom of the crude oil tank can be broken into small pieces and quickly floated and removed.
또한, 분사노즐의 하단부를 하향으로 경사지게 배치시킴으로써, 분사되는 세척수가 와류현상을 일으켜 부상되는 슬러지를 중앙으로 몰아 용이하게 제거할 수 있다. In addition, by arranging the lower end of the spray nozzle to be inclined downward, the sprayed washing water creates a vortex phenomenon, so that floating sludge can be easily removed by driving it to the center.
