Definitions
- the invention relates to a device for producing a pure liquid from a raw liquid, in particular for producing fresh water from salt water, with at least one evaporation device for evaporating raw water that can be supplied therefrom and at least one condensation device connected to the steam outlet at least one upstream evaporation device for condensing the feed Steam, a pressure drop being provided between the evaporation device and the condensation device.
- a device of this type is known from DE 102 60 494 B3.
- the evaporation device and the condensation device are evacuated to achieve a low boiling temperature.
- the drive machine to which the steam can be applied can be expediently designed as a steam engine, preferably as a membrane steam engine, which has two working spaces which are separated from one another by a movable working element, preferably connected to a pushing and pulling element, and which are alternately connected to the evaporation device or control means by means of a control valve Condensing device can be connected.
- a steam engine preferably as a membrane steam engine, which has two working spaces which are separated from one another by a movable working element, preferably connected to a pushing and pulling element, and which are alternately connected to the evaporation device or control means by means of a control valve Condensing device can be connected.
- the steam supply to the drive machine can advantageously be controlled in such a way that the steam supply to the enlarging work space is interrupted before this work space has reached its greatest expansion, which enables the steam to expand and thus improve the efficiency.
- Another expedient measure can consist in the control valve being designed as a slide valve which can be actuated by means of the movable working member. In this way there is practically self-control of the steam engine.
- the drive machine can be assigned a generator that can be driven to generate electricity.
- FIG. 1 is a functional diagram of a seawater desalination device according to the invention.
- Figure 2 shows an example of the drive machine indicated in Figure 1.
- the main field of application of the present invention is the desalination of sea water, i.e. the production of fresh water from salt water with simultaneous generation of electrical energy.
- Arrangements suitable for this each contain an evaporator side and a condenser side.
- a dash-dotted dividing line A is shown in FIG. 1, the evaporator side being to the right of this dividing line and the condenser side to the left.
- the evaporator side contains an evaporation device 10 which can be evacuated by means of an associated evacuation device 3.
- the evaporation device 10 consists of a heater 11, which is designed here as a solar collector, and a die- sem downstream separator 12 for the separation of steam and water.
- the pressure reduction which can be achieved with the aid of the evacuation device 3 brings about a low boiling temperature, so that the energy which can be supplied to the water with the aid of the heater 11 in the form of a solar collector is easily sufficient for evaporation.
- the salt water is kept ready in a higher-level raw water tank 1, which can be acted upon by a pump 2 with salt water taken from the sea, for example.
- a condensation device 23 which contains a condenser 24 designed here as a tubular condenser and a cooling device 39 assigned to it, which can be designed as a spray device to which raw water can be applied.
- An evacuation device 25 is assigned to the condenser 24, by means of which a pressure reduction in the interior of the condenser 24 to which steam can be applied can be brought about.
- the pure water obtained in the condenser 24 is received in a pure water tank 20 which, like the raw water tank 1, is arranged elevated.
- the evaporation device 10 and the condensation device 23 are connected to one another by a connecting line 47 leading from the steam outlet of the separator 12 and leading to the steam inlet of the condenser 24.
- This can be provided with a shut-off valve 48.
- the evaporation device 10 is filled with raw water and the condensation device 23 with pure water. This is followed by an increase in volume that can be achieved with the aid of the evacuation devices 3 and 25 without ventilation, which leads to a reduction in pressure. As a result, as already mentioned, the boiling temperature is low.
- the steam generated in this way flows as a result of its expansion effort from the evaporation device 10 via the connecting line 47 to the condensation device 23 and condenses there to water.
- the structure and the mode of operation of the device described so far are described in detail in DE 102 60 494 B3 mentioned at the beginning, to which reference is made to avoid repetition.
- the evaporation taking place in the evaporation device 10 results in a certain pressure increase as a result of the resulting increase in volume, which leads to the pressure drop between the evaporator device 10 and the condensation device 23 already mentioned. If the energy supply caused by the heater 11 is large enough, a lower degree of evacuation could also be provided on the evaporator side than on the condenser side.
- the pressure drop that arises between the evaporator device and the condenser device is used according to the invention for energy generation.
- a drive machine 70 which is only indicated schematically in FIG. 1, is provided, which is arranged in an associated loop 71 of the connecting line 47, so that the steam flowing from the evaporator device 10 to the condensation device 23 flows over the drive machine 70.
- a work machine 72 which is also only schematically indicated in FIG. 1 can be driven. It can expediently be an electrical energy generating generator.
- the loop 71 is designed as a secondary loop branching off from the connecting line 47 and opening into it, which can optionally be switched into the flow path of the steam.
- the connections of the loop 71 are located in front of and behind the above-mentioned shutoff valve 48 assigned to the connecting line 47.
- a further shutoff valve 73 is located in the loop 71, expediently in the branch of the loop 71 on the flow side. close and the shut-off valve 73 are open, the flow path of the steam leads over the loop 71.
- the steam does not flow over the loop 71, but without detour via the drive machine 70 angry condenser 24.
- the evaporation device 10 and the condensation device 23 are separated evacuated from each other.
- shut-off valves 48 and 73 are closed.
- the shut-off valves 48 and 73 can advantageously be controlled automatically. They are expediently designed as valves which can be controlled by means of a central control device. Of course, manual control would also be conceivable for simple cases.
- the prime mover 70 may be a steam turbine.
- the drive machine 70 is expediently designed as a steam engine in the form of a piston or membrane steam engine.
- a membrane steam engine is preferred. Such an embodiment is based on FIG. 2.
- the membrane steam engine shown in FIG. 2 contains two working spaces 75, 76 which are separated by a movable member, here in the form of a membrane 74, and which can be enlarged or reduced in opposite directions.
- the working spaces 75, 76 can be alternately connected to the evaporation device 10 or condensation device 23 by means of an assigned control valve 77 and can be enlarged or reduced in opposite directions in this way.
- the membrane 74 is deflected to one or the other side.
- FIG. 2 shows an end position with solid lines and an opposite end position as well as a middle position with broken lines.
- the reciprocating movement of the membrane 74 is used to drive the working machine 72.
- the membrane 74 is connected to a flange-mounted rod 78, which cooperates with a connecting rod 79, which in turn actuates a crank 80 assigned to the working machine 72.
- the rod 78 forming a pushing and pulling element is, as already explained thinks connected by the membrane 74 between the receiving flanges 81 with the membrane 74 and led out on both sides via correspondingly sealed passages 82 in the opposite walls of the housing 74 receiving the membrane 74 which extend transversely to the rod axis.
- the control valve 77 is expediently designed as a slide valve, the slide of which is displaceable through the membrane 74.
- a rocker arm 84 is provided, which is connected on the one hand to the rod 78 and on the other hand to the slide of the slide valve forming the control valve 77.
- the housing of the valve comprising the slide has two connections 85, 86 assigned to the working spaces 75, 76 and three connections 87, 88, 89 assigned to the connecting line 47.
- connection 86 to 89 mentioned are so arranged and the slide of the valve 77 is like this formed that in each case one work space 75 or 76 is connected to the evaporation device 10 and the other work space 75 or 76 to the condensation device 23 and that a switchover takes place in each end position of the membrane 74.
- the steam supply to the enlarging work space 75 or 76 is expediently controlled in such a way that the steam supply is terminated before the work space 75 or 76 in question has reached its greatest extent and accordingly the movable working element, here the diaphragm 74, has reached its end position.
- the remaining stroke can then be accomplished by the expansion of the steam, which has a favorable effect on the efficiency that can be achieved. Stopping the supply of steam at least half of the stroke is a preferred measure.
- the control valve 77 can be designed and actuated accordingly.
- the control valve 73 assigned to the loop 71 can be constructed and operated accordingly.
- the control valve 73 is designed as a valve which can be controlled automatically, preferably by means of a central control device.
- the working machine 72 is expediently designed as a generator, with the aid of which electric current can be generated, which can be fed into a power grid.
