Definitions

  • the invention relates to a recuperative spiral heat exchanger, with partition walls running in a spiral shape between the fluid material flows which have the usable temperature gradient, two adjacent partition walls each including a flow channel for one of the two material flows between them and the spiral space located between two flow channels the flow path for the other Flow forms.
  • Spiral heat exchangers are known. Such heat exchangers with spirally arranged flow channels can advantageously be operated in the countercurrent principle and thereby enable large exchange areas in a small space.
  • a spiral heat exchanger has the disadvantage that the flow paths lying in a spiral and therefore relatively long lead to high pressure losses. Long flow paths also make it difficult to securely seal the heat exchanger. Its cleaning is problematic and the operation with higher pressure differences requires an above-average design and construction effort.
  • the invention has for its object to design a spiral heat exchanger so that the disadvantages mentioned do not occur.
  • the spiral is designed as a multi-start or multi-arm spiral by arranging a plurality of flow channels.
  • each material flow can be divided between the spiral arms, with the advantage that either the spiral flow channels between the inlet and outlet of the respective material flow are relatively short, or a correspondingly higher throughput is possible, both advantages without reducing the actual heat exchanger area can be achieved, the dimensions of which must be adapted to the achievable order of magnitude of the performance of a heat exchanger.
  • a spiral heat exchanger designed in accordance with the invention can thus achieve the full performance for which it is designed, owing to the given heat exchanger surface, without the disadvantages of conventional spiral heat exchangers of conventional design to be accepted.
  • a heat exchanger designed with a multi-course spiral also has the advantage that it can be manufactured easily since the individual flow channels are relatively short and consequently the bending of the partition walls into the spiral shape is also easy because the individual turns are only slightly intertwined.
  • the spiral heat exchanger is further improved in that it consists of two multi-course spirals which have opposite directions of rotation.
  • each flow channel within one of the spirals can be even shorter, since the total length of each flow channel can be predetermined by its course within both spirals.
  • the connection of two opposing spirals gives each flow channel an approximately S-shaped course, with the S-bends each lying within one of the spirals.
  • spiral formation of the heat exchanger surfaces facilitates their manufacture and enables relatively inexpensive manufacture.
  • the spirals are preferably e.g. bent from sheet metal strips standing upright next to each other, two sheet metal strips each enclosing a flow channel between them, which is covered at the top and bottom by a cover, e.g. outer housing walls, is closed.
  • the inflow and outflow openings are each arranged in a housing area corresponding to the center of the spirals.
  • Corresponding line connections e.g. Connection pieces can be provided.
  • the drawing shows a schematic sectional view of a spiral heat exchanger with a lower housing wall 1 and box-shaped side walls 2.
  • the heat exchanger surfaces are arranged spirally in the manner shown.
  • a material flow can be supplied via inflow openings 3 - 3 '''. Since there are four inflow openings and a flow channel 4 - 4 '''is connected to each of the inflow openings 3 - 3''', the material flow supplied is distributed over the four flow channels, each of which has two adjacent partition walls 5, 6, here referred to the example of the flow channel 4, limited.
  • the flow channels 4 - 4 "'are interlaced in a spiral and thus form a multi-course, clockwise spiral. Between the individual flow channels 4 - 4"' there are free spiral spaces, which also serve as flow channels for a second stream of material that passes through the opening 9 is directed.
  • This second stream of material is fed through a single inflow opening of larger diameter, which is arranged in the left, counterclockwise spiral and is designated by 7.
  • This second spiral has the outflow openings 8 - 8 '' ', via which the first stream of material which enters via the inflow openings 3 - 3' '' of the right spiral is discharged again.
  • the outflow opening 8 is thus located at the end of the flow channel 4, which branches off from the inflow opening 3.
  • the remaining, respectively assigned inflow and outflow openings 3 '- 3 "' and 8 '- 8"' each have the same index.
  • the second stream of material flowing in via the larger inflow opening 7 in the left spiral enters the spiral spaces between the flow channels in regions indicated schematically by arrows and flows through the spiral spaces to the right spiral and thus in counterflow to the stream of material supplied to the right spiral, where it flows through the outflow opening 9 located there emerges again from the housing of the heat exchanger.
