Description

석회가 첨가된 이멀션유{Emulsion oil including limestone }Emulsion oil including limestone

본 발명은 연소시 황산화물 및 매연의 발생을 크게 줄일 수 있는 이멀션유의 제조방법에 관한 것으로서 보다 상세하게는 중유를 연료로 사용하는 연소장치의 유해 배출물질을 줄이기 위해 석회수로 이멀션유를 제조하여 연료로 이용하는 이멀션유 제조방법에 관한 것이다.The present invention relates to a method for producing emulsion oil that can greatly reduce the generation of sulfur oxides and soot during combustion, and more particularly to produce emulsion oil with lime water to reduce harmful emissions of the combustion device using heavy oil as fuel. It relates to an emulsion oil production method used as a fuel.

일반적으로 중유를 연료로 사용하는 화력발전소, 철강업, 해운업 등에서는 배연가스에 함유된 SO2를 저감시키기 위한 기존의 탈황시스템은 부가적인 배연 탈황장치를 설치하여 석회석(CaCO3)이나 소석회[Ca(OH)3] 슬러리를 배연가스에 접촉시켜 SO2를 흡수하여 석고(CaSO4·2H2O)로 만들어 회수하는 방법이 사용되고 있고, 또는 황함유량이 0.5%중유를 0.3%로 탈황시킨 중유를 사용하는데 이는 리터당 20원정도의 가격인상은 불가피하고 상기의 방법들을 이용하여 제품생산시 제조원가의 상승으로 인한 산업경쟁력이 저하되는 문제가 있다.In general, the desulfurization system for reducing SO 2 contained in flue gas in thermal power plants, steel industry, and shipping industries using heavy oil as fuel is provided with an additional flue gas desulfurization system to install limestone (CaCO 3 ) or lime (Ca). OH) 3 ] A method of contacting the slurry with flue gas to absorb SO 2 into gypsum (CaSO 4 · 2H 2 O) to recover it, or to use sulfur oil containing 0.5% desulfurized heavy oil and 0.3% desulfurized heavy oil. This is a price increase of about 20 won per liter is inevitable, and there is a problem that the industrial competitiveness due to the increase in manufacturing cost during the production of the product using the above method is lowered.

따라서, 본 발명은 상기와 같은 문제점을 해결하고자 이멀션유를 제조시 물 대신에 석회석(CaCO3)이나 소석회[Ca(OH)3]를 용해시킨 석회수를 중유와 혼합하여 기존의 중유를 사용하면서 황산화물, 매연, 질소산화물 등 유해배출물을 크게 줄이고 열효율을 높이는 효과가 있는 이멀션유를 제조하는 방법을 제공한다.Therefore, in order to solve the above problems, the present invention uses sulfuric acid while mixing limewater with heavy oil by dissolving limestone (CaCO 3 ) or slaked lime [Ca (OH) 3 ] instead of water when preparing emulsion oil. The present invention provides a method for producing an emulsion oil having an effect of greatly reducing harmful emissions such as cargo, soot and nitrogen oxides and increasing thermal efficiency.

도1 본 발명에 따른 이멀션유 제조의 흐름도1 is a flow chart of the emulsion oil production according to the present invention

도2 종래의 물-중유 이멀션유의 수적분포 사진2 is a water droplet distribution photograph of a conventional water-heavy oil emulsion oil.

도3 본 발명에 따른 석회수-중유 이멀션유의 수적분포 사진Figure 3 is a photograph of the distribution of lime water-heavy oil emulsion oil according to the present invention

본 발명은 상기의 목적을 달성하기 위해 안출된 것으로서 석회수와 중유를 혼합하여 이멀션유를 제조한다. 일실시예로 석회와 물을 혼합하여 석회수를 만들고 믹서를 이용하여 중유와 상기의 석회수를 이멀션유화 한다. 제조된 이멀션유는 펌프로 가압하여 연소장치의 노즐로 공급된다The present invention has been made to achieve the above object to produce an emulsion oil by mixing lime water and heavy oil. In one embodiment, lime and water are mixed to make lime water and emulsion oil of the heavy oil and the lime water is used by using a mixer. The prepared emulsion oil is pressurized by a pump and supplied to the nozzle of the combustion device.

물-중유 이멀션유 내의 수적분포 사진(도2)과 석회수-중유 이멀션유의 수적분포 사진(도3)을 비교하면 수적의 크기가 차이가 없음을 알 수 있고, 상기의 이멀션유 내의 물은 연소시 순간적인 증발에 의해 미세폭발을 일으켜 미립화가 촉진되고 이로 인해 매연이 저감된다.Comparing the water droplet photograph (Fig. 2) in the water-heavy oil emulsion oil and the water droplet photograph (Fig. 3) of the lime water-heavy oil emulsion oil, it can be seen that there is no difference in the size of the water droplets, and the water in the emulsion oil is burned. Instantaneous evaporation causes microexplosion, facilitating atomization and thereby reducing soot.

석회수-중유 이멀션유내의 물이 연소로에서 증발되면 석회가 남게되며, 상기의 석회입자는 연소로에서 SO2를 흡수하여 석고입자로 배출되며 따라서 배기가스 중의 황산화물이 크게 줄게되고 또한 상기의 석회 및 석고 고체입자는 복사열전달을 증가시켜 화염온도를 낮출 수 있어 질소산화물을 줄이면서 열효율이 증가시킨다.When the water in the lime water-heavy oil emulsion oil evaporates in the combustion furnace, lime remains, and the lime particles absorb SO 2 from the combustion furnace and are discharged as gypsum particles, thereby greatly reducing sulfur oxides in the exhaust gas. Gypsum solid particles can increase the radiant heat transfer and lower the flame temperature, reducing the nitrogen oxides and increasing the thermal efficiency.

상기의 제조 방법에 따라 본 발명은 중유를 연료로 사용하기 위해 비교적 고가인 황함유량이 적은 중유를 사용하거나 탈황장치를 설치하지 않고도 환산화물의 배출을 저감시킨다. 또한 연소로 내에서 석회 및 석고의 고체입자가 복사열전달을 증가시켜 화염온도를 낮출 수 있어 질소산화물을 저감시키고 열효율을 증가시킨다.According to the production method described above, the present invention reduces the emission of oxides without using heavy oil having a relatively high sulfur content or installing a desulfurization device to use heavy oil as fuel. In addition, the solid particles of lime and gypsum in the combustion furnace can increase the radiant heat transfer to lower the flame temperature to reduce the nitrogen oxides and increase the thermal efficiency.

이로써 중유를 연료로 사용하는 장치에 본 발명을 적용하면 청정연소 및 열효율 증가를 얻을 수 있어 환경규제와 고유가 시대에 대응하여 산업경쟁력 향상에 효과가 있다.Thus, when the present invention is applied to a device using heavy oil as a fuel, clean combustion and thermal efficiency can be increased, thereby improving industrial competitiveness in response to environmental regulations and high oil prices.
