  • the flange elements lying on the inlet side of the column body are designed as rectangular receiving containers, while the flange elements arranged on the outlet side are formed in two parts and include an annular opening, the flange elements forming a receiving container between Plate heat exchanger and first flange elements and the two-part flange elements are arranged between cylinder shell elements and plate heat exchanger or between plate heat exchanger and lower first flange elements.
  • Baffle plates are advantageously arranged downstream of the pipe sockets of the column body which feed the process medium.
  • this serves as a pressure vessel for the plate heat exchanger enclosed by it, all feed spaces for the process medium being joined to the gap-side or tube-side channels exclusively by welded connections, so that additional seals are completely eliminated .
  • the process temperatures and pressures can therefore be increased significantly.
  • an exchange of such column bodies according to the invention e.g. possible for maintenance purposes in the simplest way, without having to insert new seals inside the column body. Sealing bodies are only located between the individual column bodies and their associated compensators in order to absorb unavoidable thermal expansions within the column.
  • Another advantage of the design of the column body according to the invention is that all the essential weld seams for producing such a column body can be attached from the outside. It is therefore easy to check the required weld connections for their strength and tightness from the outside.

  • two shaped sheets 30 embossed in this way are mirror-inverted one on top of the other by means of first weld seams formed as roller weld seams on their opposite, unembossed edge regions, the plate elements of which plate-like openings - gaps 35 - form gap-like openings with their mutually facing surfaces.
  • Each plate pair is juxtaposed with an adjacent plate pair.
  • the second welding seams - referred to as the front flat seam - connecting the adjacent edges, which are referred to as forehead butt joints, are firmly and pressure-tightly connected such that the mutually facing surfaces of the individual plate pairs form tubular openings 34.

There are therefore four webs 50 per plate heat exchanger 25, each of which extends over the entire edge length of the stack and, in cooperation with the column body to be described, bring about a fluid-free, seal-free separation between the gap and tube sides of the stack.
  • a column body having the shape of a cylinder section for the seal-free reception of a plate heat exchanger will now be described in detail with reference to FIGS. 2 to 4.

  • the bellows-like compensator, provided with reinforcing rings 70, is made of pressure- and heat-resistant material (e.g. PTFE) and also encloses the discharge and inlet side of two adjacent column bodies in a pressure-tight manner.
  • the completely welded plate heat exchanger is likewise pressure-tightly connected to the column body solely by welded connections and all flow channels within the column body are also pressure-tightly welded.
  • Each column body forming a pressure and temperature stage of the heat exchanger column is therefore constructed without any seal, so that it functions reliably over long operating times even under difficult operating conditions.
  • Such a column body can be removed simply by loosening the screws 69 of the flange connection. as possible by loosening the connection of the tabs 59 between the column body and support frame. Maintenance and cleaning work can therefore be carried out in the simplest way. Since seals are missing from the column body, cleaning agents which dissolve lime and silicate can be passed through the entire column even without removing the column body, so that in particular cleaning work can be carried out at any time if necessary.
