Definitions

  • the invention relates to a compressor which is lubricated and / or cooled by means of a lubricating medium.
  • the invention relates to a method for lubricating and / or cooling a compressor.
  • compressor are below any compressor designs, in particular screw, rotary vane, Roots compressor, etc., to understand, in which by means of a lubricating medium is carried out a lubrication and / or cooling of at least one point of the compressor.
  • lubricating medium usually commercially available lubricating oils - such as ester oils, polyolester oils, etc. - are used. These lubricating oils are used for example in a screw compressor essentially the dynamic sealing of the screws of the compressor and beyond the cooling of the screw compressor.
  • lubricating oil passes into the medium to be compacted or compressed by means of the compressor. It is therefore usually necessary to connect the compressor with an oil separator. In this oil separator then carried out as far as possible separation of the lubricating oil from the compressed medium. The separated lubricating oil is after its separation - if necessary - cooled and fed back to the compressor. Since - as described above - permanently lube oil losses occur, the recirculating lubricating oil must be added regularly to the lost amount of lubricating oil.
  • Object of the present invention is therefore to provide a generic screw compressor and a generic method for lubricating and / or cooling a compressor, which avoids the aforementioned disadvantages.
  • a generic compressor which is characterized in that the lubricating medium is an ionic liquid.
  • the inventive method for lubricating and / or cooling a compressor is characterized in that the compressor is lubricated and / or cooled by means of an ionic liquid.
  • Ionic liquids are low-melting, organic salts with melting points between 100 and -90 0 C, wherein most of the known ionic liquids are already in liquid form at room temperature. In contrast to conventional molecular liquids, ionic liquids are entirely ionic and therefore show new and unusual properties. Ionic liquids can be adapted comparatively well by varying the structure of anion and / or cation and by varying their combinations in terms of their properties to given technical problems. For this reason, they are often referred to as so-called "Designer Solvents". With conventional molecular liquids, however, only a variation of the structure is possible.
  • ionic liquids In contrast to conventional molecular liquids, ionic liquids also have the advantage that they have no measurable vapor pressure. This means that, as long as their decomposition temperature is not reached, they do not evaporate in the slightest traces, even in a high vacuum. from that result in the properties of incombustibility and environmental friendliness, as ionic liquids consequently can not escape into the atmosphere.
  • the melting points of known ionic liquids are defined as below 100 0 C.
  • the so-called liquidus area - this is the range between melting point and thermal decomposition - is usually 400 ° C or more.
  • ionic liquids have a high thermal stability. Often their decomposition points are above 400 ° C. The density and the mixing behavior with other liquids can be influenced or adjusted in the case of ionic liquids by the choice of the ions. Ionic liquids also have the advantage that they are electrically conductive and thereby can prevent electrical charging - which represent a potential hazard.
  • ionic liquids have lubricating and / or cooling properties which are in no way inferior to those of conventional lubricants.
  • ionic liquids have the advantage that their complete separation from the compressed medium with a comparatively small amount of equipment is possible.
  • Compressors in which an ionic liquid is used as the lubricating medium do not require any constructive modifications compared to conventional compressors. Furthermore, there is no deterioration of the properties of the selected compressor design and also the compression of the medium to be compressed takes place in an identical manner. Thus, no changes in the compressor design used as well as the compressor associated lubricant circuit are required.
  • a carryover of the ionic liquid by the compressed medium is now no longer possible, since ionic liquids - as mentioned above - have no vapor pressure and due to this property a complete and technically easy separation of the ionic liquid from the compressed medium in a compressor downstream of the separator feasible is. Furthermore, when using an ionic liquid as a lubricant, it is ensured that the medium to be compressed or compressed in the ionic liquid does not dissolve.
  • ionic liquids In addition to most lubricating oils, ionic liquids also have the advantage that their lubricating properties are constant over a much wider temperature range.
  • Lubrication and / or cooling of a compressor allow for the first time the compression (high purity) media in which the separation of the lubricant or medium in unproblematischer manner take place and contamination of the compressed medium can be effectively prevented.
