Die Erfindung betrifft die Herstellung von destilliertem Wasser unter besonderer Nachwärmung des Kondensationskühlwassers an deh Wandungen des Verdampfers vor der Ver-• 5 dampfung.The invention relates to the production of distilled water with special reheating of the condensation cooling water on the walls of the evaporator before the 5 steaming.

Es ist an sich bereits bekannt, das zu destillierende Kondensationskühlwasser, das also im Kondensator vorgewärmt '., ist, vor seinem Eintritt in ■ den Verdampfer in einem aufIt is already known per se, the condensation cooling water to be distilled, that is to say preheated in the condenser '., is, before it enters the evaporator in one

To be reheated to the boiling point. Happened here the water also partially open containers in which ventilation can take place.

Es ist ferner an sich bekannt, daß das an der Decke des Kondensators sich bildende Wasser durch eine Rinne aufgefangen und von da in die Kühlschlange geleitet wird.It is also known per se that the Covering the condenser, the water that forms is collected by a gutter and from there in the cooling coil is routed.

Gegenstand der vorliegenden Erfindung ist nun ein Destillierapparat mit Vorwärmang des Kondensationskühlwassers an einem an der Decke der Destillierblase angeordneten Raum, bei welchem in der Destillierblase ein besonderer Fangtrichter zur Drosselung des Dampfes derart vorgesehen ist, daß er auch gleichzeitig das an der Decke des Verdampfers sich bildende Kondensat auffängt und zusammen mit dem gedrosselten Dampfe dem Kondensator zuführt. Bekanntlich ist es bei den neueren Destillierapparaten als vorteilhaftes Konstruktionsprinzip anerkannt, daß zur möglichst rationellen Ausnutzung der in Frage kommenden Wärmeenergien die Zuführungsleitungen zu dem Verdampfer und die AbführungsleitungenThe subject of the present invention is now a still with preheating of the condensation cooling water at one at the Ceiling of the still arranged space, in which in the still a special Catching funnel is provided for throttling the steam in such a way that it can also be used at the same time that which forms on the ceiling of the evaporator Collects condensate and together with the throttled steam the condenser feeds. It is known to be an advantageous design principle in the newer stills recognized that for the most rational possible use of the possible Heat energies the supply lines to the evaporator and the discharge lines

des zu kondensierenden Dampfes aus dem Verdampfer möglichst langgestreckt und auf möglichst großer Fläche miteinander in Berührung bleibend aneinander vorbeigeführt werden. Für derartige Apparate ist es von großem Vorteil, daß vor Austritt des Dampfes aus der Destillierblase derselbe mit verhältnismäßig großer Energie zur Verfügung steht, was durch die vorliegende Erfindung in besonders vorteilhafter Weise dadurch erreicht wird, daß der Dampf durch einen Fängtrichter zwischen dem hocherhitzten Vorwärmungsraum oberhalb der Destillierblase und dem Fangtrichter selbst am oberen Ende der Destillierblase erhitzt und gedrosselt wird. Da die Wassertemperatur in dem Nachwärmungsräume oberhalb der Destillierblase eine besonders hohe ist, so wirkt dieselbe gemeinsam mit der Drosselung dahin, daß der Dampf an dieser seiner Austrittsstelle aus der Destillierblase eine besonders hohe' Wärme und Druckenergie noch mit sich führt und daher besonders geeignet ist, die noch nachfolgenden langgestreckten Leitungen bis zu seinem Austritt als destilliertes Wasser aus dem Apparat wirtschaftlicher Weise zu durchfließen.

For such apparatus it is of great advantage that the steam is available with relatively high energy before the steam emerges from the still, which is achieved by the present invention in a particularly advantageous manner that the steam through a collecting funnel between the highly heated preheating space above the still and the drogue itself is heated and throttled at the top of the still. Since the water temperature in the reheating room above the still is particularly high, it works together with the throttling to ensure that the steam at this point of its exit from the still carries a particularly high level of heat and pressure energy and is therefore particularly suitable to flow through the following elongated lines until it emerges as distilled water from the apparatus in an economical manner.

Claims

bladder converges and from a smaller, underlying funnel without loss can be intercepted. The apparatus consists of a main attenuator and around these secondary evaporators 2 arranged in any number. Below the main evaporator is the condenser 4 arranged and above the main evaporator to achieve the required pressure the breather 3.

In the main evaporator 1, a steam heating coil 24 is arranged, which is used to heat the water that is in the main evaporator and through the corresponding nozzle connections 2 ^a in the 'secondary evaporator 2 is located.

The mode of operation of the device is as follows:
The cold water penetrates through the connection piece 5 in the lower part of the condenser 4 and rises upwards in the cylinder in which any condensation device, for example a mill coil 6 or the like, is provided. The water that collects in the upper part 7 of the condenser is preheated to about 60 ° as a result of the condensation process. An increase in the temperature of the preheated water above this temperature is achieved 'by the fact that the cooling water rises through the pipe 8 upwards and in the upper part of the main evaporator ι under its cover 9 and above the partition 10 arranged in the upper part of the evaporator 1 enters the closed space thus formed and is further heated there by the heat of the evaporator up to about 95 °. From the space formed between the walls 9 and 10, the water, preheated to 95 °, rises through the lines 12 into the vent 3 for example as usual

must run, an overflow 11 through which. the excess water is drained away. The water, which is used for distillation, runs down through the pipe 13 and passes through a float tap 14, which is actuated by a float 15 inside the main evaporator 1, and further through the pipe 16 and the connection piece 17 into the main evaporator. The necessary water is therefore always let into the interior of the evaporator through the float tap and the water level in it is always kept at the same level. In the evaporator 1, as a result of the action of the heat through the heating tube 24, steam is now formed, which rises upwards and to a small extent on the lower wall 10 of the space enclosed between the walls 9 and 10 because there is a slightly lower temperature in this space is condensed. As a result of the invention, the steam is throttled here between the reheater and the collecting funnel and is thus better able to gradually, ie particularly economically, dissipate its energy on the long line until it emerges as a distillate. The condensate formed in the bubble is then intercepted by the drogue 18 and flows together with the vapors through the two lines i8 "and the. Coils 19 'of the side boiler 2. In these passing through the nozzle 2 ^a with the water space e of the main Evaporator are connected, a further evaporation takes place, which also leads to a relatively low formation of condensate on the ceiling of the secondary evaporator 2, wherein 'through the funnel 20, the steam is throttled again, at the same time this condensate is also collected again and through the lines 20 "and 22 as well the connection piece 23 of the candlestick coil 6 is fed, namely together with the condensate and the steam of the main evaporator, which flow through the coils 19 of the secondary evaporator 2.

It is also remarkable the effect of the ventilator 3. The warmed to 95 ° cooling water is in the vent completely free of pressure, and heated by the heating 95 ⁰ gases can flow off through the deaerator before the water through the line 13 for evaporating the main evaporator ι is supplied.

The steam space of the main evaporator 1 is cleared with the steam of the secondary evaporator 2 connected by pipes 21. ■
