Description

Impurity filtering and separating device for lubricating oil production Technical Field The invention relates to the field of impurity separation of lubricating oil, in particular to an impurity filtering and separating device for lubricating oil production. Background Lubricating oils are liquid or semisolid lubricants used in various types of automobiles and mechanical equipment to reduce friction, protect machinery and workpieces, and mainly play roles in lubrication, auxiliary cooling, rust prevention, cleaning, sealing, buffering and the like. In the process of lubricating oil production, the steps of acid-base neutralization, flocculation sedimentation, screening impurity removal and hydrofining are needed to be sequentially carried out, wherein the steps of acid-base neutralization and screening impurity removal are all steps of removing redundant impurities in the lubricating oil by sedimentation, the hydrofining is carried out by charging hydrogen into the lubricating oil, so that unsaturated hydrocarbon, olefin, diene, aromatic hydrocarbon and other substances in the lubricating oil can be hydrogenated and saturated to become saturated hydrocarbon and the like, the quality of the oil is improved, sulfur, oxygen and nitrogen in the lubricating oil are converted into hydrogen sulfide, water and ammonia in the hydrofining process, ammonia is recovered after being treated by an ammonia washing tower, the hydrogen sulfide is discarded after being treated as waste, but the hydrogen sulfide has good waste utilization prospect, and the following chemical equation can be known: 2H 2S+3O2=2H2O+2SO2 (when fully combusted) -equation 1 2H 2S+O2=2H2 O+2S (when not fully combusted) -equation 2 SO 2+H2O=H2SO3 (sulfate ion solution) -equation 3 2H 2SO3+O2=H2SO4 (sulfuric acid solution) -equation 4 According to the formulas 1 and 2, the hydrogen sulfide can generate sulfur dioxide and sulfur after the combustion reaction of oxygen, the sulfur can be used as a monomer for manufacturing products with high economic effects such as rubber, gunpowder, sugar and the like, the sulfur dioxide can produce sulfuric acid after the reaction with water and oxygen, the sulfuric acid still has high-efficiency use value as a common chemical, but the comparison of the formula 1 and the formula 2 shows that the environment required in the process of preparing the sulfuric acid or the sulfur is different, namely, the combustion degree is controlled and the input amount of oxygen is different, so that sulfur dioxide gas and elemental sulfur coexist in the reaction furnace body, and because water is generated during the combustion of the hydrogen sulfide, the elemental sulfur and other impurities are mixed and then are settled to the furnace bottom of the reaction furnace, and the moisture can be evaporated after the reaction furnace is heated, so that the elemental sulfur and other impurities are mixed and hardened on the furnace bottom of the reaction furnace, the heat conduction efficiency of the reaction furnace is influenced, and the yield of the sulfur dioxide is influenced, and the explosion of the reaction furnace is caused even due to uneven heat conduction.
