Definitions

  • the invention relates to a side channel compressor according to the preamble of claim 1 and 2 respectively.
  • a multi-stage radial compressor is known from US Pat. No. 2,786,626, in which a cooling liquid is injected into the deflection bend provided between adjacent compressor stages for cooling. Intensive cooling is achieved by the evaporation of the cooling liquid.
  • the invention has for its object to provide a side channel compressor of the generic type so that an intensive cooling of the same is achieved.
  • a reduction in the intake volume of the side channel compressor can be avoided by arranging the injection nozzle or injectors approximately in the circumferential center of the compressor housing lying between the inlet and outlet openings.
  • the cooling liquid By introducing the cooling liquid at a point further away from the inlet opening, there are no repercussions on the suction behavior of the side channel compressor on. This can be explained by the fact that the contact caused by the injection of the coolant results in a volume reduction of the gas, ie a reduction in pressure. Since the additional volume required for the injected coolant is largely compensated for by the reduction in volume of the gas, there is no significant change in pressure in the injection area which influences the intake behavior of the side channel compression.
  • the injection nozzle or injection nozzles are arranged on the housing of the compressor stage or compressor stages downstream of the input compressor stage. Since there is a higher temperature level in the downstream compressor stage, the cooling has a particularly intensive effect.
  • FIG. 1 and 2 designate two side-channel compressors assembled to form a multi-stage compressor unit.
  • the outer housing parts 3 and 4 of the two side channel compressors 1 and 2 are supplemented by an intermediate housing part 5 to complete compressor housings, in which there are impellers 8 and 9 arranged on a common, rotatably mounted shaft 6 and provided with conveyor blades 7.
  • a side channel 10 is formed laterally to the conveyor blades 7 by a corresponding bulging of the housing parts 3, 4 and 5.
  • An injection nozzle 13 is arranged on the intermediate housing part 5 approximately in the middle of the circumference between the inlet opening 11 and the outlet opening 12 of the intermediate housing part 5. Via this injection nozzle 13, for example, water can be injected into the side channel 10, the evaporation of which cools the gas conveyed by the side channel compressor.
  • the injection nozzle 13 is attached to the intermediate housing part 5 at an incline such that its injection direction corresponds as closely as possible to the direction of flow of the conveyed gas at the installation location of the injection nozzle 13.
  • This arrangement of the injection nozzle largely prevents a disturbance in the gas flow due to eddy formation.
  • the mixture of gas and cooling liquid then enters from the side into the spaces between the conveyor blades 7, so that a hard impact of the cooling liquid particles on the conveyor blades 7, which leads to cavitation damage, is largely excluded.
