Description
技术领域technical field
本发明属一种压缩机润滑剂、特别是二氧化硫压缩机的润滑剂领域。The invention belongs to the field of lubricant for compressors, in particular to lubricants for sulfur dioxide compressors.
背景技术Background technique
二氧化硫在常温下，是无色有刺激臭味的有毒气体，密度比空气重2.26倍，标准状况下密度为2.75g/L，易溶于水（常温常压下为1:40），沸点是263K，熔点197K，易液化，超临界二氧化硫的超临界温度为157.6℃，临界压力为7.98MPa。它是重要的化工原料，用途广泛。在制糖业，二氧化硫是亚硫酸蔗汁澄清工艺法的澄清剂和漂白剂。糖厂中使用的二氧化硫是通过在燃硫炉中燃烧硫磺获得的，其燃硫炉占地面积大；二氧化硫气体容易泄漏，操作复杂。此外，二氧化硫的流速控制不好，会导致糖浆的清净脱色质量不稳定，同时也影响产品中的残留量控制。用超临界压缩法压缩气态二氧化硫，不仅可以获得高浓度液态的二氧化硫，而且可以控制二氧化硫供应量，解决糖浆色值波动、糖质量不稳定的问题。用超临界压缩法压缩二氧化硫，其理论和技术都是较为简单可行的，但却对压缩机的选择和应用，特别是对压缩机的润滑油的使用，提出了更高的技术要求。At normal temperature, sulfur dioxide is a colorless, toxic gas with a pungent odor. Its density is 2.26 times heavier than that of air. The density under standard conditions is 2.75g/L. It is easily soluble in water (1:40 at normal temperature and pressure), and its boiling point is 263K, melting point 197K, easy to liquefy, the supercritical temperature of supercritical sulfur dioxide is 157.6°C, and the critical pressure is 7.98MPa. It is an important chemical raw material with a wide range of uses. In the sugar industry, sulfur dioxide is a clarifying agent and bleaching agent in the sulfite cane juice clarification process. The sulfur dioxide used in the sugar factory is obtained by burning sulfur in a sulfur furnace, which occupies a large area; sulfur dioxide gas is easy to leak, and the operation is complicated. In addition, the flow rate of sulfur dioxide is not well controlled, which will lead to unstable decolorization quality of the syrup, and also affect the control of residues in the product. Using supercritical compression to compress gaseous sulfur dioxide can not only obtain high-concentration liquid sulfur dioxide, but also control the supply of sulfur dioxide to solve the problems of syrup color fluctuation and sugar quality instability. The theory and technology of compressing sulfur dioxide by supercritical compression method are relatively simple and feasible, but it puts forward higher technical requirements for the selection and application of compressors, especially the use of lubricating oil for compressors.
压缩机用以压缩气体、提高气体压力或输送气体，应用广泛。按压缩机工作原理不同，可分为速度式和容积式。容积式压缩机又分为活塞式和往复式，其润滑系统可以分为与压缩介质直接接触的内部润滑和外部润滑两种。内部润滑系统直接与压缩介质接触，对润滑油的要求更高，其主要作用是在相对摩擦表面之间形成液体层，分开运动部件表面的直接接触，以减少运动副的磨损，减少摩擦表面的能量消耗，同时还起到清洗、冷却、润滑、密封、防锈和防腐的作用。本发明主要应用于二氧化硫压缩机的内部润滑。在二氧化硫压缩罐装工艺中，压缩机排气温度高，压力大，工况苛刻。长期处于这样的工况对压缩机油的氧化安定是非常不利的。此外，由于二氧化硫具有弱酸性，性质较活泼，选择压缩机油要特别谨慎。将普通的压缩机油使用于二氧化硫压缩机，油品很容易被氧化变质，其氧化产物表现为积炭、胶膜和油泥等，这会对压缩机造成严重的损坏，并且存在安全隐患。使用于二氧化硫压缩机的润滑油遇到的问题归结为：油品易被二氧化硫稀释和氧化变质，易产生积炭、油泥和漆膜，热氧化安定性不足，防腐抗锈性能仍需提高等。因此，研制出具有较高的热氧化安定性、抗结焦、清净分散性、防锈和防腐等性能的二氧化硫压缩机专用油具有重要意义。Compressors are used to compress gas, increase gas pressure or transport gas, and are widely used. According to the different working principles of the compressor, it can be divided into speed type and volume type. Positive displacement compressors are divided into piston type and reciprocating type, and their lubrication systems can be divided into two types: internal lubrication and external lubrication that are in direct contact with the compressed medium. The internal lubrication system is directly in contact with the compressed medium, and has higher requirements for lubricating oil. Its main function is to form a liquid layer between the relative friction surfaces, separating the direct contact of the moving parts surface, so as to reduce the wear of the moving pair and reduce the wear of the friction surface. Energy consumption, but also play the role of cleaning, cooling, lubrication, sealing, rust prevention and corrosion protection. The invention is mainly applied to the internal lubrication of sulfur dioxide compressors. In the sulfur dioxide compression canning process, the compressor exhaust temperature is high, the pressure is high, and the working conditions are harsh. Long-term working conditions like this are very detrimental to the oxidation stability of compressor oil. In addition, due to the weak acidity of sulfur dioxide and its active nature, special care should be taken when selecting compressor oil. When ordinary compressor oil is used in sulfur dioxide compressors, the oil is easily oxidized and deteriorated, and the oxidation products are carbon deposits, film and sludge, etc., which will cause serious damage to the compressor and pose a safety hazard. The problems encountered in lubricating oil used in sulfur dioxide compressors can be attributed to: the oil is easily diluted and oxidized by sulfur dioxide, and it is easy to produce carbon deposits, sludge and paint film, insufficient thermal oxidation stability, and anti-corrosion and anti-rust performance still need to be improved. Therefore, it is of great significance to develop a special oil for sulfur dioxide compressors with high thermal oxidation stability, anti-coking, clean and dispersible properties, anti-rust and anti-corrosion properties.
