Definitions

  • the present invention relates to an improvement in heatexchangers and more particularly to a method for improving t-he transfer of heat from one fluid to another: the cooling fluid may be liquid or gaseous and the fluid giving up heat is gaseous.
  • the invention also relates to a device for the application of the said method, and to heat-exchangers of all types, so designed as to allow the application of the said method.
  • the object of the present invention is to remedy or at least minimise these disadvantages by effecting not only a marked improvement in the heat-exchanges, but also providing a simpler construction of the exchangers, ensuring a worthwhile improvement in their performances without thereby increasing their cost.
  • the invention provides a method for improving the transfer of heat from one fluid to another in a heat-exchanger, the cooling fluid being liquid or gaseous, and the fluid giving up the heat being gaseous, which consists in introducing an auxiliary liquid, which does not vaporise under working conditions, into the gaseous stream of hot fluid on its entry into the exchanger, and separating the gaseous phase from the liquid phase at the outlet from the exchanger.
  • the invention also provides a heat-exchanger for carrying out this method, and comprising a bundle of tubes inside which the hot Ifluid circulates, the said tubes being in contact through their outer surface with a cooling fluid, wherein a distribution chamber is located in the neighborhood of the end of the said bundle of tubes through which the said hot fluid enters the exchanger, through which chamber the said tubes pass and which is supplied with an adjustable quantity of auxiliary liquid by an adjustable delivery pump and injection elements to introduce a pre-determined quantity of the said auxiliary liquid into the said tubes, the said auxiliary liquid mixing with the said hot fluid, and wherein an element designed to allow the separation of the said auxiliary liquid and the said hot fluid, is provided in the neighborhood of the end of the bundle of tubes through which the said fluid leaves the exchanger.
  • FIG. 1 is a diagrammatic view of the present heat exchanger
  • FIG. 2 is an enlarged horizontal, sectional view taken on line 22 of FIG. 1.
  • the heat-exchanger under consideration has a bundle of straight tubes in which a gaseous fluid circulates which is to give up its heat to a second fluid or cooling fluid.
  • the hot gas enters the exchanger through a supply pipe 1, then circulatesin the bundle of tubes 2 along a path indicated by the arrows a, and is then evacuated by an exit pipe 3.
  • the cooling liquid circulates in a conventional manner, in counterfiow, in the direction of the arrow b. It is led into the exchanger by an entry tube 4, then, after flowing over the outer surface 5 of the tubes 2, moving transversely across the baflies constituting the partitions 6, it comes out again through an evacuation tube 7.
  • an auxiliary liquid is mixed with the gaseous stream circulating in the bundle of tubes 2, without the said liquid vaporising under the temperature and pressure conditions obtained in the exchanger.
  • the auxiliary liquid drawn from a reservoir 8 by means of an adjustable delivery pump 9, is sent through a pipe 10 following the path of the arrow 0, into a chamber 11 arranged between two plates such as 12 arranged in the upper part of the exchanger.
  • each of the tubes 2 is provided with a series of injection elements 13, made up, for example, of simple narrow holes or orifices, through which droplets of the auxiliary liquid pass to mix with the gaseous stream circulating inside the tubes.
  • the auxiliary liquid-gas mixture passes tangentially into a cyclone type separator 14, where, whilst the gas is evacuated through the pipe 3, the liquid is sent to the reservoir 8 by a pipe 15.
  • the invention is not limited to the foregoing case, in which the exchanger has a straight bundle of tubes. Indeed it is possible to design the tubes in any other shape: hair-pin tubes, coiled tubes, etc. connected to liquid-gas separators of any known type. Lastly, the choice of the auxiliary liquid is determined solely as a function of the working conditions of the exchanger, and,
  • a process as defined in claim 1 including recirculating said separated auxiliary liquid from said outlet .and reintroducing it as droplets into said hot gaseous fluid adjacent said inlet end.
  • a heat exchanger for improving the transfer of heat from a stream of hot gaseous fluid to a cooling fluid comprising: a housing having an inlet for said stream of hot gaseous fluid and an outlet; a bundle of heat exchange tubes through which said hot gaseous fluid flows disposed within said housing with the inlet end of said tubes being 7 in open communication with said housing inlet and with iliary liquid, which will not vaporize at the temperature of said hot gaseous fluid, into each of said tubes adjacent the inlet thereof for mixing with said stream of hot gaseous fluid and forming a film on the internal wall of said tubes; and separator means connected with said housing outlet for separating said gaseous fluid from said auxiliary liquid.
  • a heat exchanger as defined in claim 5 wherein said means for introducing said auxiliary liquid in droplets includes uniformly calibrated, injection elements provided in the wall of said tubes adjacent said inlet end thereof for forming said droplets of a uniform size and for imparting to said droplets a gyration as they enter said stream of hot gaseous fluid.
  • said means for introducing said auxiliary liquid in droplets includes uniformly calibrated injection elements provided in the wall of said tubes adjacent the inlet end thereof for forming said droplets of a uniform size; a variable delivery purnp having an inlet and an outlet; means connecting said pump inlet with said auxiliary liquid in said separator; and means connecting said pump outlet with said injection elements for recirculating said auxiliary liquid through said heat exchanger.
