背景技术Background technique
我国钢铁行业每年产生大量的废油，这些废油往往劣化程度不高，经过简单的处理即可循环使用。虽然在世界范围内废油回收工艺的研究早已开展并使用，但目前国内尚未研究出一套针对于钢铁企业废油的再生处理工艺。因此，钢铁企业每年产生的大量废油不能得到有效的合理回收，不仅造成了石油资源的大量浪费，而且造成了环境污染。my country's iron and steel industry produces a large amount of waste oil every year. These waste oils are often not highly deteriorated and can be recycled after simple treatment. Although the research on waste oil recycling technology has been carried out and used in the world, a set of regeneration treatment technology for waste oil in iron and steel enterprises has not been researched in China at present. Therefore, a large amount of waste oil produced by iron and steel enterprises every year cannot be effectively and reasonably recovered, which not only causes a large waste of oil resources, but also causes environmental pollution.
近年来，国内也出现一些较为先进的废油处理工艺，逐渐将减压蒸馏，溶剂精制与白土工艺相结合。蒸馏酸洗—白土精制工艺，其原料容易获得，投资成本较低，工艺流程较为简单，适用于多种类型的润滑油再生的优势，使得国内大部分厂家均使用该工艺，但硫酸精制时产生的酸渣难以处理，同时产生气体SO2对环境污染大，并对设备造成腐蚀。CN 103194308 A公开了一种利用废油制备再生基础油的方法，该方法将废油依次通过一级过滤、二级过滤、三级过滤、雾化脱水、吸附脱色的设备。采用该方法废油的过滤速度快、效率高、不易堵塞，但是该方法仅适用于劣化程度很低的废油，对于钢铁企业产生的废油，经过该步骤处理往往达不到理想的效果。CN 102977989 A公开了一种废润滑油循环回收再生生产工艺，该工艺生产效率高、产品特性稳定、无二次污染，但往往全套设备造价昂贵，且设备移动安装不便捷。因此，上述工艺均无法满足钢铁企业对于废油处理的需要。In recent years, some more advanced waste oil treatment processes have emerged in China, gradually combining vacuum distillation, solvent refining and clay process. Distillation pickling-white clay refining process, the raw materials are easy to obtain, the investment cost is low, the process flow is relatively simple, and the advantages of being suitable for the regeneration of various types of lubricating oils make most domestic manufacturers use this process, but sulfuric acid refining produces The acid slag is difficult to deal with, and at the same time, the gas SO2 is produced, which pollutes the environment and causes corrosion to the equipment. CN 103194308 A discloses a method for preparing regenerated base oil from waste oil. In this method, the waste oil is sequentially passed through the equipment of primary filtration, secondary filtration, tertiary filtration, atomization dehydration, and adsorption decolorization. Using this method, the waste oil can be filtered quickly, with high efficiency, and is not easy to be clogged, but this method is only suitable for waste oil with a low degree of deterioration. For waste oil produced by iron and steel enterprises, the ideal effect is often not achieved after this step. CN 102977989 A discloses a waste lubricating oil recycling and regeneration production process, which has high production efficiency, stable product characteristics, and no secondary pollution, but the cost of a complete set of equipment is often expensive, and the equipment is not convenient to move and install. Therefore, none of the above processes can meet the needs of iron and steel enterprises for waste oil treatment.
