Definitions
- Thermal processes which purify saline or impure water by evaporation and condensation, or multiple distillation. Such methods work particularly economically if the heat used for evaporation after the condensation is used again for evaporation and in this way several times.
- Plate heat exchangers made of rustproof materials are known. These are also used in the chemical industry for condensation and for evaporation. Such devices are assembled from plates, which are produced in large numbers in a simple manner and are accordingly particularly inexpensive
- the method according to the invention relocates a modification of the multiple distillation process to a plate heat exchanger. These are easy to manufacture and assemble and are accordingly inexpensive. Plate heat exchanger units are installed in rows and connected by a pipe system ( Figure 1)
- live steam (2) and sea water (4) are fed to the heat exchanger units, and condensate (3), the pure water produced as product (6) and the superfluous, somewhat concentrated sea water (5) are removed from them.
- the units are also connected to a vacuum system (7).
- the internal circuitry of the plate heat exchanger unit is shown in FIG. 2.
- the effects (10) are arranged between the evaporator / preheater (8) and the condenser (9), in which the evaporation and condensation processes are repeated and also the preheating of the sea water takes place.
- FIG. 3 The processes within an effect are shown in FIG. 3.
- the steam (12) generated in the previous effect condenses on the condensation side and evaporates part of the preheated sea water (11) on the evaporator side.
- the non-evaporated, somewhat thickened sea water (13) is led to the next effect, where it is fed in again together with the preheated sea water (18).
- the vapor generated in the evaporator is first passed through a droplet separator (14) before it is directed to the condensation side of the next effect (12).
- the heat transfer in the individual effects only takes place if there is sufficient temperature difference.
- the required temperature difference corresponds to a difference in the saturation pressure. This pressure difference between the effects is generated by hydrostatic water columns on special pressure drop plates (15 and 20).
- FIGS. 4 and 5 A cross section of the vertically placed plate heat exchanger is shown in FIGS. 4 and 5, the section once through the condensation-side (FIG. 4) and once through the evaporator-side (FIG. 5) connection opening Plate heat exchanger goes.
- steam (12) and product (pure water) (16) from the previous effect are supplied.
- the steam condenses on the condensation side (17), the condensate (16) is led through the water column of the pressure drop plate (15) to the next effect, the necessary pressure difference being created by the hydrostatic pressure of the water column.
- feed (18) and non-evaporated sea water (13) are fed to the evaporator side (19).
- the non-evaporated sea water (13) flows over the pressure drop plate (20) to the onset of the next effect, where it is mixed again with the preheated feed (18).
- the preheating takes place on the part (22) of the evaporator plates reserved for preheating, heated by the condensing steam on the condensation side (17).
- the sea water (4) is divided in the divider (23) into the individual feed water flows (18) and the cooling water flow of the condenser (9).
- the feed water flows (18) flow through the preheater (22) in parallel channels. In this way, preheating takes place in countercurrent, with small temperature differences, with the temperature of the sea water added to the effects always having the correct value.
- FIG. 6 A section parallel to the plates on the evaporator side in effect is shown in FIG. 6.
- the evaporation takes place in vertical, narrow channels.
- the flow in the individual channels is intermittent, the channels work alternately.
- the subdivision into a relatively large number of channels (21) brings about the stability of the total flow. Since the cross section of the evaporator is relatively large in relation to the cross section of the transition to the next effect, the sea water is recirculated in the evaporator by flowing back through the channels which are not currently active to the evaporator inlet.
