Definitions

  • the invention relates to a processing and/or operating machine comprising an ionic liquid as the operating liquid.
  • fluids preferably oils are used as lubricating fluid, sealing fluid, barrier fluid, pressure transfer fluid, i.e. quite generally as operating liquid, in the field of processing machines such as pumps, in particular vacuum pumps, rotary vane pumps, vane-cell pumps, piston pumps, diaphragm pumps etc., in compressors such as screw compressors etc. and in piston machines.
  • processing machines such as pumps, in particular vacuum pumps, rotary vane pumps, vane-cell pumps, piston pumps, diaphragm pumps etc.
  • compressors such as screw compressors etc. and in piston machines.
  • vapour pressure of such fluids determines the minimum pressure in a processing machine, with, in the case of an evaporation of the fluid, this having to be eliminated from the process gas in a complex manner.
  • Hydraulic diaphragm pumps are a typical example of the disadvantages described. As a result of their hermetic properties with a simultaneously high compressive rigidity and conveying accuracy, such hydraulic diaphragm pumps are preferably employed for critical conveying tasks such as conveying of toxic, environmentally relevant or hygiene fluids, for conveying at high pressures and for the precise dosage of any desired fluids.
  • the hydraulic fluid which is used as a pressure transfer fluid from the piston to the diaphragm, represents a frequently limiting factor.
  • mineral oil or synthetic oil e.g. polyglycol with a multiplicity of additives or special oil is used for this purpose.
  • glycerine is also used in food technology or biotechnology.
  • glycerine requires the application of inhibitors of biological decomposition. Nevertheless, decomposition cannot be prevented.
  • the thermal limit in this case is merely 95° C.
  • the viscosity is adjusted by mixing with water in a complex manner.
  • a further typical example of the disadvantages described is presented by liquid ring vacuum pumps.
  • the rotating fluid ring is required to seal the impeller chambers vis-à-vis each other and for transferring the necessary compression energy onto the gas.
  • the vapour pressure of the ring liquid limits the minimum achievable intake pressure level. At this intake pressure, the impeller chambers fill completely with the evaporating operating liquid and the suction capacity of the liquid ring vacuum pump drops to zero.
  • Operating liquids used in practice are preferably water with a vapour pressure at ambient temperature of approximately 23 mbar and oils with a vapour pressure of approximately 1 mbar thus permitting merely operation in the so-called coarse vacuum range.
  • other compressors need to be consequently necessarily used for this purpose.
  • these have disadvantages compared with the use of a liquid ring vacuum pump.
  • their use for compressing hydrocarbons is possible only by taking great safety precautions since the compressors that can be used require an explosion-protected design.
  • DE 10 2204 024 967 A1 discloses the use of ionic liquids as operating liquid (i.e. the fluid to be conveyed) for thermal absorption pumps, absorption refrigerating machines and thermal transformers.
  • Gas conveying machines, hydraulic diaphragm pumps, liquid ring vacuum pumps and piston machines using ionic liquids as operating liquids are not disclosed in DE 10 2004 024 967 A1.
  • the present invention is therefore based on the object of designing a processing and/or operating machine of the type appropriate for its kind which exhibits a fluid as operating liquid such that the disadvantages illustrated are avoided without loosing the advantages of the operating liquids previously employed.
  • this invention relates to a device, in particular a pump, comprising an ionic liquid as operating liquid medium, in particular as separating fluid and/or hydraulic fluid.
  • a second embodiment of the present invention consists of a hydraulic diaphragm pump which is characterized in that it comprises an ionic liquid as hydraulic fluid.
  • a third embodiment of the present invention consists of a liquid ring vacuum pump which is characterized in that it comprises an ionic liquid as ring liquid. This extends the operating range of the pump into the fine vacuum range.
  • a fourth embodiment of the present invention consists of a piston-containing machine which is characterized in that it is designed with a piston oscillating in a cylinder in the form of a fluid piston or a fluid master piston positioned in front which consists of an ionic liquid.
  • a gas, a non-miscible fluid of low density or a fluid of high density can be conveyed.
  • the invention moreover, relates to a process for operating the above-mentioned device by using ionic liquids as operating liquid medium.
  • the invention provides a method of operating a machine comprising: including an ionic liquid as an operating fluid in the machine; and operating the machine.
  • the invention also provides a method of equipping a machine comprising: including an ionic liquid in the machine as an operating fluid in the machine.
  • operating fluid is meant a liquid employed by a machine to facilitate operation of a machine.
  • the operating fluid can serve as a lubricant, barrier fluid, hydraulic fluid, ring liquid, fluid piston or any other such fluid. It should be understood that the scope of the invention is use of an ionic liquid as an operating fluid in a machine, wherein the ionic liquid is used other than solely as a heat transfer medium.
  • FIG. 1 depicts an exemplary gas conveying machine of the invention comprising an ionic liquid.
  • FIG. 2 depicts an exemplary hydraulic diaphragm pump of the invention comprising an ionic liquid.
  • FIG. 3 depicts an exemplary liquid ring vacuum pump of the invention comprising an ionic liquid.
  • FIG. 4 depicts an exemplary screw pump of the invention comprising an ionic liquid.
  • the invention is based on the essential idea of designing a processing and/or operating machine in such a way that the operating medium provided therein, i.e. the operating liquid is an ionic liquid.
  • Ionic liquids consist of ions, i.e. anions or cations and are consequently salts. In contrast to common salts, such as sodium chloride, however, they have a lower melting point and may be fluid even at room temperature. Thus, all salts which exist in the pure form as a fluid at below 100° are considered, by definition, to be ionic liquids.
  • Ionic liquids may be referred to as liquid salts. They possess an extremely low vapour pressure (10 ⁇ 13 bar), have only a low gas solubility, are not combustible, are frequently physiologically safe and frequently thermally stable at up to more than 250° C. and suitable for lubrication.
  • the list of advantages provided by ionic liquid is long. Consequently, ionic liquids represent an environmentally friendly and resources-conserving replacement for the fluids described so far.
  • a machine or pump according to the invention will comprise ionic liquid as the working fluid or operating fluid.
  • the ionic liquid can possess one or a combination of two, three, four or more of the following properties: 1) a vapor pressure of less than 10 ⁇ 3 mbar; 2) a melting point of less than 20° C.
  • Additives can be used in combination with an ionic liquid according to the invention, such additives being those typically used in the oil and lubricant industry. Any zwitterionic or ionic commercial additive can be used. One or more additives can be used. Suitable additives include anti-wear additive, friction modifier, rust and corrosion inhibitor, antioxidant, dispersant, detergent, anti-foaming agent, pour point depressant and combinations thereof. Suitable additives are also disclosed in Patent No. [ADD] of Idemitsui, the disclosure of which is hereby incorporated by reference.
  • the ionic liquid of the invention can be used in a variety of machinery and can be used as a substitute for engine oil, gear oil, hydraulic oil, cutting fluid (coolant), way lubricant, compressor oil, quenching and heat transfer oil, rust protection oil, transformer oil, turbine oil, chain lubricant, wire rope lubricant, bearing oil, sintered bearing oil, sealing oil.
  • an ionic liquid as operating liquid in processing and/or operating machines, it is possible to advantageously influence the following parameters as desired: a) the lubricating effect; b) the compressive rigidity; c) the viscosity as a function of the temperature; d) the vapour pressure limit; e) the chemical inertness; f) the thermal inertness; g) the solubility behaviour; h) the physiological safety.
  • Ionic liquids are therefore capable of avoiding the disadvantages described so far. Because of their extremely low vapour pressure of 10 ⁇ 13 bar (liquid salt), they are capable of reaching extremely low pressures in vacuum technology and consequently avoid contamination of the process gas both in vacuum pumps and in compressors.
  • ionic liquids As a result of the use of ionic liquids, anticipated according to the invention, in process machines it is now also possible to operate the above-mentioned piston machines with a fluid piston consisting of an ionic liquid and to avoid the disadvantages described at the same time.
  • the use of ionic liquids also provides the advantage that a reaction with the substance conveyed is impossible since it is inert to a large extent.
  • liquid ring vacuum pumps as a result of the use, according to the invention, of ionic liquids as ring liquid, to employ these pumps also in the fine vacuum range.
  • liquid ring vacuum pumps can be used instead of the previously used screw compressors, piston compressors, rotary vane cell compressors etc. and their great advantages regarding robustness, reliability and process safety can fully be exploited.
  • a paddle wheel is arranged eccentrically in the case of a liquid ring vacuum pump in a cylindrical housing.
  • the operating liquid present in the housing forms a co-rotating, concentrically formed fluid ring as a result of the rotation of the paddle wheel.
  • the fluid ring closes off the gas volumes in the chambers.
  • the paddles immerse, in the upper area, completely into the fluid ring such that the chamber volume is completely filled with operating liquid.
  • the fluid ring detaches itself from the impeller hub and forms a crescent-shaped cavity.
  • the gaseous fluid to be conveyed is sucked into the operating cavity by the control disc apertures arranged on the front surfaces on the impeller. Shortly before the gas-filled chamber volume reaches its maximum, the suction slit terminates and the chamber is sealed off by the control discs, the impeller paddles and the fluid. The fluid ring then migrates again towards the hub and compresses during this process the gas like a piston. As soon as the pressure slot apertures are reached, the compressed gas is pushed out.
  • the operating liquid needs to fulfill above all three functions in liquid ring vacuum pumps, namely firstly the function of a moving piston with the operating pulses of suction, compaction and pushing out, secondly the sealing function to seal the scoop cavities from each other and thirdly the absorption of heat of compression.
  • part of the operating liquid is continually expelled through the pressure slot, the same amount of fresh fluid being fed in via a fluid channel in the shaft hub of the pump. As a result of this ongoing recooling, a constant temperature of the operating liquid is reached.
  • the vapour pressure of the operating liquid limits, the lowest possible suction level to be reached in the suction nipple of the pump. If the suction pressure drops to a value equal to or in the vicinity of the vapour pressure of the fluid, cavitation and consequently a complete drop in performance of the pump occur.
  • liquid ring vacuum pumps enter an area of application which had previously been covered by rotary vane pumps and exterior vane pumps, eccentric piston pumps or injectors.
  • liquid ring vacuum pumps can exhibit their pump-imminent advantages such as maximum reliability, quasi isothermic compression and absence of oil in the compression process in the now possible field of application of the fine vacuum (10 ⁇ 3 -10 ⁇ 1 mbar) and they open up, in this way, an entirely new way of process control and application possibilities.
  • the ionic liquids used according to the invention as operating liquid are compounds composed of cations and anions.
  • the ionic liquid can comprise one such compound or a mixture of two or more such compounds.
  • a cation can be selected from the group consisting of:
  • the anion can be selected from the group consisting of [PF 6 ] 31 , [BF 4 ] ⁇ , [CF 3 CO 2 ] ⁇ , [CF 3 SO 3 ] ⁇ , [(CF 3 SO 2 ) 2 N] ⁇ , [(CF 3 SO 2 )(CF 3 COO)N] ⁇ , [R 4 —SO 3 ] ⁇ , [R 4 —O—SO 3 ] ⁇ , [R 4 —COO] ⁇ , Cl ⁇ , Br ⁇ , I ⁇ , [NO 3 ] ⁇ , [N(CN) 2 ] ⁇ , [HSO 4 ⁇ or [R 4 R 5 PO 4 ] ⁇ , wherein:
