Definitions

  • the invention relates to a liquid ring vacuum pump with an upstream pre-compressor and a downstream liquid separator and heat exchanger for transferring heat between the operating fluid which can be returned to the pump and which has a high boiling point in relation to water and cooling water.
  • This generic term refers to a system such as that described in Siemens brochure E 7251046.
  • the vacuum pump announces the gas and pushes it with part of the operating fluid, e.g. Oil, in the liquid separator arranged on the pressure side.
  • the compressed gas leaves the separator through an overhead pressure port, while the operating fluid flows back into the vacuum pump.
  • the heat absorbed by the operating fluid through the compression and friction is dissipated to cooling water by means of a heat exchanger arranged in the operating fluid circuit.
  • the cooling water of e.g. 15 ° C is warmed up to 25 to 30 ° C at the operating fluid temperatures normally used and is generally no longer usable for another process unless the temperature is raised to a higher level by a complex heat pump.
  • the friction and compression heat that ultimately comes from the operating motor of the vacuum pump is therefore usually lost.
  • the object of the present invention is to make at least part of this heat usable for the overall system in terms of energy optimization.
  • This object is achieved in that the operating temperature of the operating fluid in the pump and separator is above the boiling point of the cooling water and energy for the operation of the pre-compressor can be taken from the steam generated in the heat exchanger. In this way, not only can the heat generated by compression of the pumped medium and by friction be reused without great effort, but (in all "wet” vacuum processes) the heat content contained in the extracted steam component.
  • the steam generated in this way can serve as a propellant for the radiator.
  • a side channel gas ring compressor is used as a pre-compressor in a manner known per se, the steam can be used as a drive means for a turbo machine coupled to the compressor, e.g. a turbine.
  • the steam produced in the system is advantageously separated as far as possible in a condenser located between the pre-compressor and the pump.
  • the operating fluid 5 obtained in the separator 6 is returned to the pump 4 by a pump 62 at a temperature of 120 ° C.
  • the energy for operating the radiator 2 is essentially extracted from the energy of the operating liquid. This is done in such a way that cooling water 8 15 0 C is first preheated in the condenser 3 by means of a heat exchanger 32 to 40 ° C and a temperature T 2 of, for example. From here it then passes via a heat exchanger 64 in the immission cooler 63 to a heat exchanger 61 in the separator 6.
  • the cooling water flowing through the heat exchanger 61 evaporates due to the temperature of 130 ° C. of the operating liquid 5 and reaches the temperature as saturated steam 81 T 3 ⁇ 120 ° C via line 7 as a blowing agent to the radiator 2.
  • a gas ring side channel compressor can be used as the pre-compressor, the drive machine of which is driven by the steam generated.
  • the condenser 3 can also serve as a condenser connected downstream of the turbomachine.
