Definitions

  • the present invention relates to a heat exchanger and a system for recovery 5 of thermal energy from waste water.
  • an object of the present invention is to provide for a heat exchanger and a system for recovery of thermal energy from waste water.
  • a heat exchanger in accordance with the present invention for recovery of thermal energy from waste water comprises an outer tube, an inner tube for waste water, and a control element, wherein said inner tube is arranged inside said outer tube in such a way that a space is formed between said inner tube and said outer tube and wherein said control element is arranged in said space and is arranged to guide a medium in a helical movement around the inner tube so that thermal energy from said waste water is transferred to said medium.
  • the heat exchanger according to the invention ensures that thermal energy is emitted from the waste water to the medium with a high degree of efficiency. Since the medium has direct contact with the outside of the inner tube, heat transfer is very good. It is advantageous that the control element directs the medium in a helical movement, since the medium then is transported a long distance in the space between the inner and outer tube, which provides long contact time with the inner tube and thus increased efficiency. Furthermore, the heat exchanger according is advantageous with regards to the Coanda effect in that the waste water is evenly distributed over an internal surface of the inner tube which contributes to transfer of thermal energy.
  • the heat exchanger according to the invention is flexible as regards to its length, connection dimensions, and variable flow characteristics in combination with low
  • the length of the heat exchanger, the spacing of the winding of the control element, and the spacing between the inner and outer tube can be varied and adjusted according to the waste water flow.
  • a high efficiency can be achieved, since the heat exchanger can be adjusted so that very good conditions are obtained.
  • control element can be arranged to guide said medium in a space formed between the control element, an outside of the inner tube, and an inside of the outer tube.
  • a portion of the outside of the control element is arranged to face towards said space that is formed between the control element, an outside of the inner tube, and an inside of the outer tube, and a portion of the outside of the control element is arranged to face toward the outside of the inner tube.
  • the control element is thus arranged to guide said medium in a helical movement around the inner tube by at least a portion of the outside of said control element.
  • the flow path of said medium outside of the inner tube is helically shaped.
  • said medium is guided in a spiral-formed track which is defined at least partly by the inside of the outer tube, the outside of the inner tube and the control element (as, for example, a portion of the outside of the control element).
  • the outer tube, the inner tube, and the control element are thus arranged in such a way that a spiral-formed channel is formed in the space between said inner tube and said outer tube, where said medium is allowed to flow.
  • heat exchange will mainly occur from the waste water via the wall of the inner tube to said medium being guided in a helical movement around the inner tube.
  • the heat exchanger can thus in an efficient way recover thermal energy from the waste water, since the heat exchange occurs directly between said medium and the waste water via the wall of the drain tube.
  • control element can be wound around said inner tube.
  • the space between the control element, an outside of the inner tube, and an inside of the outer tube, where said medium is guided can be varied by changing the spacing of the winding of said control element.
  • the capacity of the heat exchanger can be altered and adjusted in order to optimize the flow for the heat exchanger.
  • said control element may be soldered onto said inner tube.
  • control element has a strengthening/supporting function on the inner tube.
  • Said medium directed in said space can exert a large pressure on the inner tube (the pressure may be as high as around 16 bar), and the strengthening/supporting function may thus contribute to that the inner tube can better resist this pressure.
  • said control element may be a tube that is filled, or almost filled, with a material such as some sort of filling mass, for example cement or silicon.
  • a cross-section of said control element is filled with some material.
  • said control element may be compact or solid. In other words, said control element has a cross- section that is compact or solid.
  • the tube does not have a through channel where air or liquid can flow.
  • Such an embodiment is advantageous since the strengthening or supporting function of the control element is improved.
  • said inner tube and said outer tube can be mounted parallel with the vertical plane.
  • said inner tube can be arranged centrally in said outer tube. This is advantageous since it contributes to good efficiency as the waste water flows centrally in the inner tube.
  • said outer tube may have an inlet for said medium in a lower portion of said outer tube and an outlet for said medium in an upper portion of said outer tube.
  • the inlet is provided to lead said medium to the space between the control element, an outside of the inner tube and an inside of the outer tube.
  • said inner tube may have an inlet for said waste water in an upper portion of said inner tube and an outlet for said waste water in a lower portion of said inner tube. This is advantageous since a counter flow heat exchanger is formed, which has high efficiency.
  • the edge of said inlet and/or outlet of said inner tube comprises at least one projection arranged in a direction of flow in said inner tube.
  • the projection contributes to that a slit is formed between the drain tube and the heat exchanger. This is advantageous because it
  • drain tube compensates for small discrepancies caused by that the drain tube is not mounted vertically, and also contributes to quickly and evenly distribute the waste water over the surface when it reaches the slit.
  • said inner tube may be made of copper. This is advantageous since heat transfer in copper is very good. Copper also counteracts the ability for diatoms and similar to become attached and thereby degrading heat transfer over time. This contributes to low maintenance costs.
  • said outer tube can be at least one of copper, steel, or stainless steel.
  • Steel and stainless steel have the advantage that they are inexpensive.
  • control element can be a tube.
  • control element can be shaped in a helical track around the inner tube relatively simply.
  • said control element can be a tube wound around said inner tube. This is advantageous since the drain heat exchanger can be assembled by soldering the tube to the inner tube and thereafter pushing the outer tube into place over the inner tube and the tube wound and soldered onto the inner tube. By soldering the control element to the inner tube the construction is made even more stable.
  • said control element can be at least one of copper, aluminum, or stainless steel. Said control element can also be of a material which withstands fresh water. According to one embodiment said medium can be water. This is advantageous since water has many applications.
  • the temperature of said medium when it leaves said outlet for said medium may be in the range of 8-50°C. This is advantageous since the medium can be pre-heated by the invention before it is used for various applications.
  • a system for recovery of thermal energy from waste water in accordance with the present invention comprising a heat exchanger according to the any one of the above embodiments and at least one of a water closet, a hot water dispenser arranged to heat liquid to a predetermined
  • the heat exchanger can provide the water closet, the hot water dispenser, and the shower, kitchen, and bathroom mixers with heated water.
  • the system can comprise a conduit for leading water from said heat exchanger to said hot water dispenser. This is advantageous since the hot water dispenser does not need to work as much, because the water is already heated by the heat exchanger.
  • the system can comprise a conduit for leading water from said heat exchanger to said water closet.
  • the system may comprise a conduit for leading water from said heat exchanger to said shower mixer, wherein said shower mixer is arranged to mix said water with water from said hot water dispenser.
  • the system can comprise a conduit for leading water from said hot water dispenser to said shower mixer, said kitchen mixer or said bathroom mixer, wherein said shower mixer, said kitchen mixer or said bathroom mixer is arranged to mix water with water from said heat exchanger.
  • Fig. 1 shows a cross-section of the heat exchanger according to the invention.
  • Fig. 2 shows a schematic view of a system for recovery of thermal energy from waste water according to the invention.
  • the heat exchanger according to the invention is based on the idea of saving energy by using thermal energy in the waste water to preheat water for use in, for example, bath, shower, dishwashing, clothes washing, and flushing toilets.
  • the preheated water In order to reach the desired temperature the preheated water sometimes needs to be mixed with water of an even higher temperature.
  • This water with an even higher temperature can be heated by, for example, a hot water dispenser.
  • Water heated by the hot water dispenser can be water preheated by the heat exchanger which, is then further heated by the hot water dispenser.

  • the inner tube 1 10 is arranged for leading waste water. Waste water is directed downwards in the figure and flows by means of gravitation.
  • a space 130 is formed between the inner tube and the outer tube.
  • a control element 140 extends inside the space 130. The control element is arranged to guide said medium in a helical movement around the inner tube. When a medium is led around the inner tube and waste water flows in the inner tube, thermal energy from the waste water can be transferred to the medium.
