Abstract
The invention relates to a lubricating agent of a sulfur dioxide compressor. The lubricating agent is prepared by compounding oil-soluble polyether and low-viscosity poly alpha-olefin to be base oil and mixing with various additives. The lubricating agent effectively alleviates the dilution degree on oil products caused by sulfur dioxide and avoids frictional wear due to insufficient oil film thickness caused by ultralow viscosity of the oil products, has excellent sediment controllability, does not generate carbon deposit and oil sludge, increases safety coefficient, has excellent viscosity-temperature property, low-temperature property, volatility, cooling property, high anti-shearing stability, hydrolytic stability and thermal oxidation stability, can reduce the friction coefficient of the surface of metal, and can meet the using requirement of the sulfur dioxide compressor under the harsh working condition.
Description
Technical field
The invention belongs to a kind of compressor lubricant, the particularly field of lubricant of sulfurous gas compressor.
Background technology
Sulfurous gas at normal temperatures, it is the colourless toxic gas that has pungent odor, density is heavier than air 2.26 times, normal conditions lower density is 2.75g/L, (under normal temperature and pressure, being 1:40) soluble in water, and boiling point is 263K, fusing point 197K, easily liquefaction, the supercritical temperature of overcritical sulfurous gas is 157.6 ℃, emergent pressure is 7.98MPa.It is important industrial chemicals, of many uses.In sugar-refining industry, sulfurous gas is finings and the SYNTHETIC OPTICAL WHITNER of sulfurous acid cane juice clarification Process.The sulfurous gas using in sugar refinery obtains by the sulphur that burns in brimstone furnace, and its brimstone furnace floor space is large; Sulfur dioxide gas easily leaks, complicated operation.In addition, the flow rate control of sulfurous gas is bad, can cause the peace and quiet decolouring quality of syrup unstable, and the residual quantity also affecting in product is controlled simultaneously.With overcritical compression method compressed gaseous sulfurous gas, not only can obtain the sulfurous gas of high density liquid state, and can control sulfurous gas supply, solve the fluctuation of syrup colour, the unsettled problem of saccharic amount.With overcritical compression method compression sulfurous gas, its theory and technology is all simple possible comparatively, but choice and application, the particularly use to the lubricating oil of compressor to compressor proposed higher technical requirements.
Compressor, in order to pressurized gas, raising gaseous tension or delivering gas, is widely used.Press compressor principle of work different, can be divided into speed mode and positive displacement.Positive-displacement compressor is divided into again piston-type and reciprocating, and its oiling system can be divided into two kinds of the internal lubrication that directly contacts with compression medium and external lubrications.Internal lubricating system directly contacts with compression medium, requirement to lubricating oil is higher, its Main Function is relatively between friction surface, to form liquid level, the direct contact of split movement parts surface, to reduce the wearing and tearing of kinematic pair, reduce the energy expenditure of friction surface, also play cleaning, cooling, lubricated, sealing, antirust and rot-resistant effect simultaneously.The present invention is mainly used in the internal lubrication of sulfurous gas compressor.At sulfurous gas, compress in canned technique, compressor exhaust temperature is high, and pressure is large, and operating mode is harsh.Stable to the oxidation of compressor oil in such operating mode is for a long time very disadvantageous.In addition, because sulfurous gas has slightly acidic, character is more active, selects compressor oil careful especially.Common compressor oil is used in to sulfurous gas compressor, and oil product is easy to oxidized rotten, and its oxidation products shows as carbon deposit, glued membrane and greasy filth etc., and this can cause serious damage to compressor, and has potential safety hazard.Being used in the problem that the lubricating oil of sulfurous gas compressor runs into is summed up as: oil product is easily diluted and deterioration by oxidation by sulfurous gas, easily produces carbon deposit, greasy filth and paint film, and thermal oxidation stability is not enough, and anticorrosion rust-resisting property still needs to improve etc.Therefore, develop there is higher thermal oxidation stability, the sulfurous gas compressor special oil of anti-coking, detergent-dispersant performance, the performance such as antirust and anticorrosion is significant.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of dilution of sulfurous gas to oil product that reduce, and avoids because oil film thickness deficiency causes frictional wear, and sediment monitoring ability is good, improves safety coefficient; Viscosity-temperature characteristics energy, low-temperature performance, volatility, cooling, high anti-shear stability, stability to hydrolysis, thermal oxidation stability all good, reduce frictional coefficient, meet the lubricant of sulfurous gas compressor of the harsh operating mode working conditions of sulfurous gas compressor.
The present invention solves the problems of the technologies described above with following technical scheme: adopt oil soluble polyethers and low viscosity poly-alpha olefins to be complex as base oil, and by application neural network algorithm and genetic algorithm, determine additive formula, its each component and mass percent thereof are:
Base oil is that mass ratio 45.6%～54.3% oil soluble polyethers and 45.7%～54.4% low viscosity poly-alpha olefins are compound.
Purification agent is boronation sulfonate and 60%～40% alkyl monosulfide phenates of mass ratio 40%～60% low basicity.
Dispersion agent is polyisobutene succinate.
Antioxidant preservative is dialkyl dithio amino formate.
Rust-preventive agent is that mass ratio 40%～60% organophosphorus acid type imidazolinium compounds and 60%～40% dodecenylsuccinic acid are compound.
Oxidation inhibitor is mass ratio 50%2, and 6-di-t-butyl mixed phenol and 50% 124 Triazole derivative are compound.
Extreme pressure anti-wear additives is that 50% tricresyl phosphate phenol ester and 50% amino monothioester are compound.
Kilfoam is polyacrylic ester.
Non-emulsifying agent is amine and epoxy compounds condenses.
The lubricant of sulfurous gas compressor of the present invention, has effectively reduced the dilute strength of sulfurous gas to oil product, has avoided causing because oil viscosity is too low that oil film thickness is not enough, thereby has caused frictional wear; There is good sediment monitoring ability, do not generate or seldom generate carbon deposit and greasy filth, improved safety coefficient; There is the frictional coefficient of good viscosity-temperature characteristics energy, low-temperature performance, volatility, cooling, high anti-shear stability, stability to hydrolysis, thermal oxidation stability and reduction metallic surface etc., can meet the harsh operating mode working conditions requirement of sulfurous gas compressor.
