Description
본 발명은 사무실이나 주택 등에서 전기요금이 싼 한전의 심야전기를 이용하여 난방기를 가동할 경우 전기히터에서 발생되는 열을 축열재에 효율적으로 축적시켜 전기공급이 끊긴 낮시간대에도 축적된 열이 서서히 방출되도록 하여 난방효과를 높일 수 있도록 한 심야전력 난방기용 축열재의 조성물에 관한 것이다.According to the present invention, when a heater is operated using KEPCO's late-night electricity, which is cheap in the office or a house, the heat generated from the electric heater is efficiently accumulated in the heat storage material, thereby gradually releasing the accumulated heat even in the daytime when electricity supply is cut off. It relates to a composition of the heat storage material for a midnight electric power heater so as to increase the heating effect.
종래 난방기 내부에 설치되는 내화벽돌은 용광로에 주로 사용되는 아리미나 블럭이 사용되고 있는데, 이 블럭내부 깊숙히 열기가 파고들지를 못하기 때문에 열이 쉽게 식어버리게 되고 이로 인하여 낮시간에 축적된 열에 의한 적정한 온도의 난방을 유지할 수 없는 문제점이 있었으며, 특히 아리미나의 가격이 비싸 경제성이 없는 문제점이 있었다.In the conventional refractory bricks installed inside the heater, arimina blocks, which are mainly used in furnaces, are used, and since the heat cannot penetrate deeply inside the blocks, the heat is easily cooled, and thus the proper temperature due to the heat accumulated during the daytime There was a problem that can not maintain the heating, especially the price of the arimina had a problem that is not economical.
본 발명은 이와 같은 점에 착안하여 개발된 것으로, 철강 제조공장에서 부산물로 버려지는 밀스케일(Mill Scale)을 주원료로 축열재인 블럭을 제조하여 이를 난방기 내부에 설치하면 밤 10시부터 다음날 오전 8시까지 심야전기로 가열된 전기히터에서 발생되는 열을 축열재에서 축적을 시켜 전기공급이 중단된 낮시간에 서서히 열기가 방출되므로서 동절기에 적절한 실내온도로 난방을 시킬 수 있도록 한 것을 발명의 목적으로 한 것이다.The present invention has been developed in view of this point, if manufacturing a block of heat storage material from the mill scale (Mill Scale), which is discarded as a by-product in the steel manufacturing plant and installed inside the heater, from 10 pm to 8 am the next day The purpose of the present invention is to accumulate the heat generated from the electric heater heated by the midnight electricity in the heat storage material so that the heat is gradually released during the daytime when the electricity supply is interrupted so that it can be heated to the appropriate room temperature in winter. It is.
본 발명의 축열재 제조공정도Heat storage material manufacturing process diagram of the present invention
이하 본 발명을 실시예에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to Examples.
[실시예]EXAMPLE
(1). 원료혼합공정(One). Raw material mixing process
밀스케일 20~80%, 적점토 20~70%, 물유리 5~10%(또는 모래 5~10%)의 조성으로 혼합시킨다.Mix 20-20% of mill scale, 20-70% of red clay, 5-10% of water glass (or 5-10% of sand).
(2). 분쇄, 혼합, 혼련, 숙성공정(2). Grinding, Mixing, Kneading, Aging Process
분쇄는 조크리서(Jaw Crusher)에서 하고, 혼합은 해머밀(hammer mill) 또는 롤러밀(roller mill)에서 행한 후 원료를 따로 저장하였다가 배합비율에 따라 원료별, 입도별로 혼합하고 물을 첨가하여 혼련시킨 다음 비닐등으로 덮개를 씌워서 1~7일간 방치하여 숙성시킨다. 이때 숙성시의 수분량은 3~30%로 조절한다.Grinding is carried out in a jaw crusher, mixing is carried out in a hammer mill or roller mill, and then the raw materials are stored separately, mixed by raw material and particle size according to the mixing ratio, and water is added. After kneading the mixture, cover it with vinyl and leave it for 1 to 7 days to mature. At this time, the amount of water at the time of ripening is adjusted to 3 to 30%.
(3). 성형공정(3). Molding process
축열재 블럭의 성형은 기계 성형방법으로 오일 프레스(oil press), 크랭크 프레스(crank press) 등의 성형기를 이용하여 성형시키며 배토(숙성시킨 원료)의 수분량은 3~10%가 되게 한다.The heat storage material block is formed using a molding machine such as an oil press or a crank press by a mechanical molding method, and the moisture content of the clay (maturated raw material) is 3 to 10%.
(4). 건조, 소성공정(4). Drying, firing process
성형된 블럭의 건조는 터널식 가마로를 이용하여 건조온도는 50~90℃로 한다.Drying of the molded block is carried out using a tunnel type kiln, the drying temperature is 50 ~ 90 ℃.
소성은 터널가마를 이용하고 소성온도는 700~1100℃로 하며 소성기간을 15~30시간으로 한다.Firing is carried out using tunnel kiln, firing temperature is 700 ~ 1100 ℃ and firing period is 15 ~ 30 hours.
상기와 같이 제조되는 본 발명에서 축열재의 원료로 사용되는 밀스케일은 철강제로 공장에서 철강제조시 발생되는 부산물로서 흑색을 띄며, Fe가 주성분이며 표면은 고온산화로 인한 Fe3O4로 피막된 것을 말하며,In the present invention manufactured as described above, the mill scale used as a raw material of the heat storage material has a black color as a by-product generated when steel is manufactured in a steel factory, and Fe is a main component and the surface is coated with Fe 3 O 4 due to high temperature oxidation. Saying,
물유리는 소성조제로서 주성분이 Na2O-SiO2이고 성형체의 소결을 촉진시켜주는 효과가 있으며, 이 성분은 소성온도를 낮추어 블럭의 생산단가를 낮추고 블럭 성형시 성형성을 향상시켜 주는 것이다.Water glass is a calcination aid, and its main component is Na 2 O-SiO 2 , which has the effect of promoting sintering of the molded body. This component lowers the firing temperature, lowers the production cost of the block and improves the moldability during block molding.
상술한 바와 같은 본 발명의 축열재는 종래 난방기에 사용되는 내화벽돌에 비하여 축열용량(열용량)이 커서(1.2J/g℃이상) 심야전기 공급시간인 밤 10시부터 다음날 오전 8시까지 전기히터에서 발생되는 열을 효율적으로 축적시켜 낮시간에 서서히 축적된 열을 방출하는 효과가 있고, 특히 축열 최대온도가 500~700℃가 될 경우 열쇼크에 의해 축열재가 파손되는 경우가 있으나 본 발명의 축열재는 물유리등이 혼합되어 있어 항절력 및 열쇼크에 대한 저항성이 큰 것이 특징인 것이다.As described above, the heat storage material of the present invention has a larger heat storage capacity (heat capacity) than the refractory brick used in a conventional heater (over 1.2 J / g ° C.), which is a night time electric supply time from 10 pm to 8 am the next day. Efficiently accumulate the generated heat to release the heat gradually accumulated during the day time, especially when the heat storage maximum temperature is 500 ~ 700 ℃ heat storage material may be damaged by heat shock, but the heat storage material of the present invention It is characterized by the high resistance to heat-resistance and thermal shock because water glass is mixed.
