摘要
为解决原油输送过程中易结蜡,不易流动的问题,利用太阳能代替部分传统能源对工业锅炉24 h给热,提供伴热软化水,实现了能源消耗的降低和环境保护。提出了油品储运伴热软化水太阳能预热系统,该系统主要应用于场地受限、高热值、高能耗及高污染工业上,具体表现为将太阳能高效集热装置、储热设备与工业锅炉进行结合改造,为锅炉提供预热软水,并且结合相变储热原理以满足出水温度达到工业要求,保证锅炉太阳能集热器完整、连续地运行。在理论研究的基础上,展开了大量的实验,实验结果验证了该系统的可靠性。研究结果表明,预热系统在日间日照充足时,集热效率高,相变蓄热器具有较好地蓄热和放热效果,放热时间能持续5 h^7 h以上,满足了原油输送过程对热水的需求。
Aiming at keeping the flowability of crude oil transmission and avoiding wax precipitating, traditional energy can be replaced by solar energy to heat industrial boiler, which could provide the preheating softened water to industrial boiler and reduce the energy consump- tion and environmental pollution. The solar preheating system for oil storage and transportation with thermal softened water was proposed, which mainly applied to industry with limited space, high calorific value, high energy consumption and high pollution. The definite perform- ance of the system was designed to renovate industrial boiler with the combination of solar collector and heat storage equipment to offer the preheating softened water. The latent heat storage theory was used to satisfy outlet water temperature reaching the industry requirement, and keep boiler solar collector running completely and continuously. On the basis of theoretical research, many experiments were done to test the reliability of the preheating system. The results indicate that the preheating system is of high heat colleting efficiency and the latent heat stor- age device is of great heat storage and rejecting in sunny day, which could persist heating more than 5 - 7 hours to supply the boiled water for industrial requirement.
