应用液体载热体作为传热介质的导热油加热系统是一种高效、稳定、安全、新颖的热源,这种加热系统在粮油加工部门已取得显著的节能效果。随着技术的完善,在农副产品干燥领域中,这种加热系统将会得到更为广泛的推广和应用。一、工作原理导热油加热系统是由导热油加热炉、循环油泵、过滤器、膨胀槽、贮油槽、注油泵、管道和阀门组成的一个闭式循环系统,系统中的传热介质是导热油。导热油自贮油槽经注油泵加压后进入导热油加热炉,经加热达到额定温度,然后送入用热设备,放出热能,油温下降后再由循环油泵送回炉内加热,由此反复循环,将热能由炉内输送到用热设备。
The HTF heating system using liquid heat transfer medium as a heat transfer medium is an efficient, stable, safe and novel heat source. This heating system has achieved remarkable energy-saving effect in the grain and oil processing sector. With the improvement of technology, this heating system will be more widely popularized and applied in the field of agricultural and sideline products drying. First, the working principle Heat conduction oil heating system is a closed circulation system consisting of heat conduction oil heating furnace, circulating oil pump, filter, expansion tank, sump, oil pump, pipes and valves, heat transfer medium in the system is heat conducting oil . Thermal oil from the sump by the oil pump pressurized into the HTF furnace, heated to reach the rated temperature, and then into the hot equipment, release heat, the oil temperature dropped by the circulating oil pump back to the furnace heating, which repeated the cycle , The heat transfer from the furnace to the use of heat equipment.
