Problems solved by technology

The manufacture and installation of the container is complex and time-consuming
Furthermore, maintenance of the device and cleaning of the heat exchange plates are difficult since the plate assembly and the heat exchange plates are only accessible after the container has been opened

Embodiment Construction

[0021] figure 1 A plate heat exchanger for processing media is shown. The application of desalination is described in the following description. It should be noted, however, that the present invention is not limited to this application, but can also involve any other treatments, such as the distillation of liquids.

[0022] The plate heat exchanger includes a plurality of pressure-molded heat exchange plates 1 arranged in parallel to each other and sequentially arranged in such a manner as to form a plate assembly 2. The plate assembly 2 is arranged between the frame plate 3 and the pressure plate 4. A first inter-plate gap 5 and a second inter-plate gap 6 are formed between the heat exchange plates 1. The first inter-board gap 5 and the second inter-board gap 6 are alternately arranged in the board assembly 2 in the board assembly 2 in such a way that each first inter-board gap 5 is basically composed of two second The inter-plate gaps 6 are surrounded, and each second inter-pl...

Abstract

The invention relates to a plate heat exchanger for processing media, the plate heat exchanger comprising a plurality of press-molded heat exchange plates (1) stacked on one another to form a plate assembly (2), and A first inter-plate gap (5) and a second inter-plate gap (6) are formed for the media. The first inter-panel gaps and the second inter-panel gaps are provided in an alternating sequence within the panel assembly. The plate assembly (2) surrounds the evaporation, separation and condensation sections. The evaporation portion is configured to evaporate at least a portion of the medium flowing through the gap between the first plates. The separation part is configured to separate the unevaporated liquid from the evaporated portion of the medium. The condensing portion is configured to condense the evaporated portion flowing through the gap between the first plates.

Description

Technical field [0001] The present invention generally relates to a plate heat exchanger for medium distillation, and particularly relates to the desalination of salt-containing water (such as seawater). More precisely, the present invention relates to a plate heat exchanger for processing a medium. The plate heat exchanger includes a plurality of pressure-molded heat exchange plates which are sequentially arranged in a plate assembly and formed The first inter-plate gap and the second inter-plate gap of the medium, wherein the first inter-plate gap and the second inter-plate gap are arranged in an alternating sequence in the board assembly. Background technique [0002] Desalination equipment has been manufactured many years ago, in which plate assemblies of one or more heat exchange plates form the main components of the process. The Swedish patent SE-B-464 938 discloses such a desalination device, which includes a plate assembly arranged in a cylindrical container. There is no...
