Definitions

  • the present invention relates to a device for regulating temperature and pressure in a fluid circuit such as fumes from combustion chambers.
  • the device is more particularly intended to be used for the regulation of chimney effluents.
  • An object of the invention is to provide a means for regulating a fluid, which is protected from the fluid to be regulated.
  • a fluid control device comprising a main flow conduit of the fluid to be regulated equipped with means for injecting at least one additional fluid into the main conduit selectively in at least two orientations.
  • the means for selecting the orientation of the injection is disposed outside the duct.
  • make-up fluid refers to any product having a fluid behavior.
  • the nature of the makeup fluid, its quantity, the orientation of its injection as well as its thermodynamic state variables make it possible to regulate the temperature, the pressure and the flow rate of the fluid to be regulated, without exposing moving members sensitive to the flow of the fluid. fluid to be regulated.
  • the invention is here described in application to a flue gas duct connected to a combustion chamber, such as an oven, for discharging fumes to the outside.
  • the exhaust duct is optionally connected to a flue gas treatment device for the purpose of cleaning up the flue gases before they are discharged into the atmosphere.
  • the flow direction of the fluid is indicated by a hollow arrow in the figure.
  • the regulating device is connected to the duct 1 in order to control the fumes which constitute the fluid to be regulated.
  • the regulation can relate to one or more characteristics of the fumes such as pressure and temperature.
  • the adjustment of the flue gas pressure makes it possible to regulate the pressure in the combustion chamber in order to make it safe to operate and to prevent any entry of spurious air.
  • the pressure regulation can also effectively compensate for a lack of draft of the exhaust stack.
  • the adjustment of the flue gas temperature makes it possible to satisfy anti-pollution standards and also to optimize the operation of the flue gas treatment device when the duct is equipped with such a device.
  • the device comprises a main conduit 1 for circulating the fluid to be regulated on which a nozzle 2 for supplying a makeup fluid is tapped.
  • the main duct 1 is connected to the flue gas duct to form a part of it.
  • the pipe 2 is equipped with a supply valve 2.1 and an element 2.2 for injecting the makeup fluid into the main pipe 1 in at least two directions.
  • the injection element 2.2 here consists of an annular casing delimiting the main duct 1 and having two outlets having different orientations.
  • a first outlet extends perpendicularly to the direction of the fluid to be regulated (radial injection) and a second outlet is oriented in the direction of the fluid to be regulated (axial injection).
  • This box is equipped with a movable flap 2.3 mounted in the box between the two outlets to provide a means for selecting the orientation of the injection of the makeup fluid.
  • the opening of the valve 2.1 brings a flow of additional fluid.
  • the movable flap 2.3 directs this flow towards one or the other of the outputs but can also supply both outputs simultaneously.
  • the makeup fluid flow is then divided between the two orientations.
  • the position of the movable flap 2.3 also makes it possible to distribute quantitatively the flow of fluid between the two exits.
  • the movable flap 2.3, mounted in the box is thus protected from the flow of fluid to be regulated and its aggressions.
  • the makeup fluid line 2 is connected to a tank, a fan, a pump or any other device capable of delivering the product according to the flow rate and / or the required pressure.
  • Devices acting on the temperature of the auxiliary fluid such as a heating resistor / hot water circulation tube winding helically around the pipe or a heater, act on the temperature of the auxiliary fluid. .
  • Closing the valve 2.1 terminates the control. This valve can also be used to adjust the pressure and flow rate of the makeup fluid.
  • the regulation of the fluid to be regulated therefore comprises the step of injecting at least one additional fluid into a fluid circulation duct to be regulated so as to modify at least one of the thermodynamic state variables of said fluid and also comprises a step of selecting a makeup fluid.
  • the nature, the quantity, the orientation and the thermodynamic state variables (such as pressure, flow rate, temperature) of the makeup fluid are determined according to the expected result: drop in the temperature by injection of a fluid of auxiliary cooler than the fluid to be regulated, increase of the upstream pressure by radial injection of a fluid at a pressure greater than the pressure of the fluid to be regulated.
