Definitions

  • the invention relates to a method for conveying a gas flow by means of a liquid ring machine with a paddle wheel driving the liquid ring in a housing, in which operating liquid is supplied to the liquid ring machine in order to maintain the liquid ring.
  • a method of this type for a liquid ring machine is known from DE-A 2 818 837 for vacuum generation in the production and processing of reaction resin compositions.
  • Higher molecular solvents corresponding to the reaction resin compounds to be processed are used as the operating fluid in order to prevent the formation of viscous sediments in the pump by dissolving residues of sucked-in resins, hardeners and chemical accelerators.
  • friction-reducing or flow-accelerating macromolecular substances can be added in a defined amount.
  • Such friction reducers or flow accelerators according to US Pat. Nos. 3,290,883 and 4,397,748 and EP-A 0 003 821 can be used to reduce the friction losses of flowing liquids in hydraulic systems, in sewage pipes, in conventional liquid pumps or turbines in order to accelerate the flows and thus can be used to improve the efficiency of the turbines or pumps.
  • the invention for a method for conveying a gas flow by means of a liquid ring machine of the type mentioned is based on the task of increasing the gas delivery capacity as a function of the gas intake pressure while reducing the drive power requirement and the noise emission, no constructive special measures or other constructive interventions being provided in the liquid ring machine will.
  • the macromolecular bodies in the rotating operating fluid ring do not result in an increase in the amount of operating fluid per unit of time, nor is it intended to reduce the friction of the operating fluid, but rather, surprisingly, an increase in the gas delivery rate and / or an increase in suction pressure and a reduction in the sound level can be achieved.
  • Known polymers in particular polyacrylamides, as well as surfactants or inorganic fibers can be provided as macromolecular substances, which are added as a liquid stock solution or in powder form to the liquid flow at the inlet of the liquid ring machines in question, in an amount that is matched to the mass flow rate of the flowing liquid, preferably the constant supply said friction reducer or flow accelerator for mass flow of the liquid flowing into the housing.
  • the amount of friction reducers constantly supplied is relatively small in relation to the inflowing liquid and therefore the consumption of such bodies during the operating period is correspondingly small.
  • a device for carrying out the method is indicated schematically in the drawing and explained below, a liquid flow machine being used in continuous operation.
  • the indicated liquid ring pump 1 is connected to an inflow line 2 and an outflow line 3 for the operating fluid.
  • a supply container 5 for powdered or liquid dissolved friction reducers is connected to the inflow line 2 via a metering device 4.
  • the metering device 4 is, in turn, brought into dependence on a mass flow meter 6 arranged in the drain line 3 such that, depending on the amount of the operating fluid flowing through the pump 1 per unit of time, the metering device 4 releases a quantity of friction reducer to the inflow line 2 which releases a constant proportion same per unit volume of operating fluid. This also more than compensates for the reduction in intake power caused by the temperature rise of the operating fluid.
