Embodiment Construction
[0070] figure 1 A side view of a plate heat exchanger 10 of the present invention is disclosed. In the following description, applications are described with respect to desalination of seawater, ie the feed is seawater. It is to be noted, however, that the invention is not limited to the feed being seawater, but may also relate to any other processing, such as distillation of liquids. The plate heat exchanger comprises a plurality of compression molded heat exchanger plates 12 which are arranged parallel to each other and successively so that they form a plate pack 14 . The plate pack 14 is arranged between a frame plate 16 and a pressure plate 18 .
[0071] Between the heat exchanger plates 12 a first plate gap 20 and a second plate gap 22 are formed. First plate gaps 20 and second plate gaps 22 are arranged in an alternating sequence in the plate pack 14 such that substantially every first plate gap 20 is surrounded by two second plate gaps 22 and substantially every seco...

The invention relates to a plate heat exchanger for treating a liquid feed. The plate heat exchanger includes a plate set having at least two opposing heat exchanger plates that define a plate gap between themselves. Each heat exchange plate defines a first non-corrugated gasket groove and a second non-corrugated gasket groove, whereby a first gasket element is sealed between the first gasket grooves and a second gasket element is sealed between the second gasket grooves of the opposite plate. Thus, a flow channel is established between the first gasket element and the second gasket element in the plate gap. Each heat exchange plate further defines a first outer corrugated region and a first inner corrugated region extending on opposite sides of the first non-corrugated gasket slot, and a second outer corrugated region and a second inner corrugated region extending on opposite sides of the second non-corrugated gasket slot.
Description
technical field [0001] The present invention relates to a heat exchange plate for a plate heat exchanger for processing liquid feed, a plate heat exchanger for processing liquid feed and a manufacture of a plate heat exchanger for processing liquid feed Methods. Background technique [0002] Since many years, plants for the desalination of sea water have been manufactured in which one or several plate packs of heat exchanger plates form the main components in the process. The applicant company has since some years produced a fresh water generator in which vaporization, separation and condensation take place in a plate pack. Details can be found in international application WO2006 / 104443 A1 assigned to Alfa Laval Corporate AB. It discloses a plate heat exchanger for desalination having a first type of plate gap and a second type of plate gap formed in an alternating sequence in the heat exchanger. The first type of plate gap forms the vaporization section, the separation s...
