Definitions
- the invention relates to a process or working machine with a liquid as operating fluid.
- liquids preferably oils, as a lubricating fluid, sealing fluid, barrier fluid, pressure transmission fluid , d. H. used in general as a working fluid.
- Hydraulic diaphragm pumps In this case, oil or another liquid is used as hydraulic fluid for the membrane drive and as coupling fluid between the membranes;
- Hydraulic diaphragm pumps are a typical example of the disadvantages described. Due to their hermetic properties and simultaneously high pressure rigidity and conveying accuracy, such hydraulic diaphragm pumps are preferably used for critical conveying tasks, such as conveying toxic, environmentally relevant or hygienic liquids, for conveying at high pressures and for precisely dosing any liquids. In this case, however, a multiple limiting factor is the hydraulic fluid which is used as pressure transfer fluid from the piston to the diaphragm. Usually this mineral oil or synthetic oil, for example, polyglycol with a variety of additives, or special oil is used. Due to the physiological dubiousness of this lubricant, glycerine is also used in food or biotechnology.
- glycerol requires the use of inhibitors of biological decomposition. Nevertheless, the decomposition can not be prevented.
- the thermal limit is here only 95 0 C.
- the viscosity is hereby set in a complex manner by mixing with water.
- piston machines are another typical example of the occurrence of the disadvantages described.
- a possible technical solution for special applications would be to operate them for the purpose of gas or liquid conveyance with a liquid flask or a liquid feed piston, given a sufficient difference in density and immiscibility.
- this has so far failed at the limits of the known operating fluids, and that is because in the application of aqueous liquids, the known disadvantages, such as evaporation, corrosion, toxicity, gas solubility, etc. arise.
- organic liquids since the disadvantages of evaporation, toxicity, volatility, etc. occur.
- the use of liquid metals has the disadvantages of toxicity, high cost, high density, difficult sealing, etc.
- DE 10 2004 024 967 A1 discloses the use of ionic liquids as working fluid (ie the liquid to be conveyed) for absorption heat pumps, absorption refrigerating machines and heat transformers. Gas conveying machines, hydraulic diaphragm pumps, liquid ring vacuum Recirculating and piston machines that use ionic liquids as operating fluids are not disclosed in DE 10 2004 024 967 A1.
- the present invention is therefore based on the object, a process or working machine of the generic type, which has a fluid as Railflüs- sity designed such that the disadvantages are avoided, without losing the benefits of reaching previously used operating fluids.
- this invention relates to a device, in particular a pump, comprising an ionic liquid as the operating medium, in particular as a separating liquid and / or hydraulic fluid.
- a first preferred embodiment of the present invention is a gas-conveying machine which is characterized in that it has an ionic liquid as the lubricating fluid.
- a second preferred embodiment of the present invention is a hydraulic diaphragm pump which is characterized in that it has an ionic liquid as the hydraulic fluid.
- a third preferred embodiment of the present invention is a liquid ring vacuum pump which is characterized in that it can be used as ring liquid. having an ionic liquid. This extends the working range of the pump to the fine vacuum range.
- a fourth preferred embodiment of the present invention is a piston type machine characterized in that it is configured with a piston oscillating in a cylinder in the form of a liquid piston or an upstream liquid feed piston made of an ionic liquid. Due to the oscillating movement of the liquid piston, a gas, a low-density immiscible liquid or a high-density liquid can be promoted.
- the invention further relates to methods of operating the above device using ionic liquids as the operating medium.
- the invention is based on the essential idea of designing a process machine in such a way that the operating medium provided in it, that is, the operating fluid, is an ionic fluid. This results in amazing advantages, which are set out in detail below.
- ionic liquids consist of ions, ie anions and cations, and are thus salts.
- common salts for example sodium chloride, they have a lower melting point and can be liquid even at room temperature.
- all salts which are liquid in pure form below 100 ° C. are considered to be ionic liquids.
- Ionic liquids can be referred to as liquid salts. They have an extremely low vapor pressure (10 "13 bars), have only small gas solubility, are non-flammable, are often physiologically harmless, are often thermally stable up to 250 0 C and lubricity. The list of advantages that ionic liquids , is long, so ionic liquids make one umweit- and resource-saving replacement for the previously described fluids.
- ionic liquids In the case of ionic liquids, a suitable gradual adjustment of the polarity and thus a tuning of their properties, in particular their solubility properties, is possible by suitable choice of cation and anion.
- the spectrum ranges from water-miscible ionic liquids, to water-immiscible liquids, to those that form two phases even with organic solvents.
- the clever use of these extraordinary properties of ionic liquids is the key to the successful use of these fluids in the sense of the invention.
- Ionic liquids are therefore able to avoid the disadvantages described so far. Due to their extremely low vapor pressure of 10 "13 bar (liquid salt), they can achieve extremely low pressures in the vacuum technology and at the same time avoid contamination of the process gas in both vacuum pumps and compressors.
- ionic liquids in process machines, it is now also possible to operate the aforementioned piston machines with a liquid piston, which consists of an ionic liquid, while avoiding the disadvantages described.
- the use of ionic liquids also has the advantage that a reaction with the conveyed is excluded because they are highly inert.
- liquid ring vacuum pumps due to the use according to the invention of ionic liquids as ring liquid, the use of these pumps is also made possible in the fine vacuum range.
- liquid ring vacuum pumps can be used instead of the previously used screw compressors, reciprocating compressors, rotating vane compressors, etc. be able to fully exploit their great advantages in terms of robustness, reliability and process reliability.
- a paddle wheel is eccentrically arranged in a cylindrical housing in a liquid ring vacuum pump.
- the operating fluid in the housing forms due to the rotation of the impeller a co-rotating, concentric liquid ring. This completes together with the rotor blades, the gas volumes in the chambers. Due to the eccentricity of the rotor, the blades in the upper area completely submerge in the liquid ring, so that the chamber volume is filled with operating fluid.
- the liquid ring lifts off the impeller hub and forms a crescent-shaped space.
- the gaseous fluid to be delivered is sucked into the working space by the control disk openings arranged on the end faces of the impeller.
- the suction slot ends, and the chamber is sealed by the control discs, the impeller blades, and the fluid. Then the liquid ring migrates back to the hub and compresses the gas like a piston. As soon as the pressure slot openings are reached, the compressed gas is expelled.
- the operating fluid has to fulfill in liquid ring vacuum pumps above all three functions, namely, first, the function of a moving piston with the Working cycles sucking, compressing and pushing out, secondly the sealing function for sealing the pump chambers against each other and thirdly the absorption of the heat of compression.
- a portion of the operating fluid is constantly discharged through the pressure slot, wherein the same amount of fresh liquid is supplied via a fluid channel in the shaft hub of the pump. Due to this permanent recooling, a constant temperature of the operating fluid is achieved.
- the vapor pressure of the working fluid limits the lowest suction level to be achieved in the intake manifold of the pump. If the suction pressure drops to a value equal to or close to the vapor pressure of the liquid, it cavitates and thus a complete power loss of the pump.
- oils that have a lower vapor pressure.
- oils lead to contamination of the pumped medium and pose an environmental risk.
- chemicals for example, concentrated sulfuric acid for chlorine gas compression.
- the invention provides a remedy by extending the range of application of the liquid ring vacuum pumps in the fine vacuum range due to the inventively provided use of ionic liquids. Since such ionic fluids have no appreciable vapor pressure, no cavitation occurs, so that there is no limitation of the suction pressure down. Furthermore, ionic fluids have very good lubricating properties and thus enable a shaft seal adapted to the fine vacuum. In contrast to the use of oil, there is no contamination of the delivery fluid.
- Liquid ring vacuum pumps Due to the inventively provided use of ionic liquids in process machines, in particular in liquid ring vacuum pumps, therefore their range of application is expanded into the fine vacuum range. Liquid ring vacuum pumps are thus entering a field of application previously covered by rotary and gate valves, Roots pumps or steam jet pumps.
- these have the disadvantage that the necessary oil lubrication of the impeller in the housing leads to a contamination of the pumped medium and that the removal of the heat of compression can be realized only expensive apparatus.
- inventively used as operating liquid ionic liquids are compounds which are composed of cations and anions, wherein the cation used
