Embodiment Construction

[0017]In FIGS. 1, 1a, 2, a heat transfer unit—in this case a condensing unit 20—is made up from front and back sheets 23F, 23B of corrugated material. In FIG. 1, the front sheet 23F has been removed. The corrugated sheets 23F, 23B are attached together, trough-to-trough, the troughs being held a small distance apart by spacer-strips 25. Fasteners 27 clamp the troughs of the two sheets together, onto the spacer-strips 25. The fasteners can be bolts, rivets, etc, as appropriate.

[0018]It is emphasized that the troughs of the corrugated sheets 23F, 23B do not actually make touching contact with each other, being held a distance D1 apart (FIG. 6) by the spacer-strips 25. Thus, in the areas between the spacer-strips 25, there is open space between the troughs, through which fluids can travel (i.e travel downwards) between the corrugated sheets.

[0019]Top and bottom of the sheets 23F, 23B, channel-strips 28 sealingly close off the longitudinal edges of the sheets. In use, the pressure insid...

Abstract

In an MVR evaporator, a heat exchanger core comprises several condensing units. Each unit comprises front and back corrugated sheets, arranged trough-to-trough. The units are arranged side-by-side, in peak-to-trough configuration, creating sinuous passageways between the units. Steam is fed into the units through port-pipes, and the units are physically supported via the port-pipes from steam manifolds.

Description

[0001]This invention relates to heat exchangers, and to a cost-effective manner of construction thereof.BACKGROUND TO THE INVENTION[0002]The invention will be described herein mainly as it applies to evaporators. Evaporators are used in the treatment of industrial wastewaters, in that water is evaporated from the in-stream of wastewater, thereby concentrating the contaminant in the final-water out-stream. Evaporators are used when the savings in disposal costs more than outweigh the costs of evaporation.[0003]The invention is especially applicable to mechanical vapour recompression (MVR) evaporators. Typically, in an MVR evaporator, water and steam are present together in a state of pressure-temperature equilibrium, at a pressure below atmospheric, in a vacuum chamber of a container vessel. Steam is extracted from the vacuum chamber, and is compressed in such manner that the mechanical energy of compression serves to raise the temperature, as well as the pressure, of the steam. The ...
