Description
Einrichtung zum Absaugen der Luft aus Oberflächenkondensatoren Es sind Einrichtungen zum Absaugen der Luft aus Oberflächenkondensatoren mittels Wasserstrahlsauger bekannt, bei welchen der der abgesaugten Luft hEigemischte Wasserdampf durch mittels einer Einspritzdüse @eingeführtes Kondensat kondensiert wird, welches durch die Kühlwasserzuführung des Oberflächenkondensators hindurchgeleitet und dadurch gekühlt ist. Bei diesen Anlagen wird das entstehende Kondensat dem Kondensatorkreislauf wieder zugeführt.Device for extracting air from surface condensers Es are devices for extracting air from surface condensers using a water jet suction device known in which the water vapor mixed in with the extracted air is caused by means of an injection nozzle @ is condensed condensate introduced, which through the Cooling water supply of the surface condenser passed through and thereby cooled is. In these systems, the condensate that forms is fed into the condenser circuit fed back.
Erfindungsgemäß soll -die Einspritzdüse an einer in b@ezug auf den Luftabsaug@estutzen höher gelegenen Stelle der Luftabsaugeleitung angeordnet sein. Dabei sind ein besonderer Kühlwasserkreislauf und ein besonderer Oberflächenkondensator für diesen Kühlwasserkreislauf nicht erforderlich.According to the invention, the injection nozzle should be connected to one in relation to the Luftabsaug @ estutzen be arranged at a higher point of the air suction line. There is a special cooling water circuit and a special surface condenser not required for this cooling water circuit.
Die Zeichnung zeigt ein Ausführungsbeispiel des Erfindungsgegenstandes in schematischer Darstellung.The drawing shows an embodiment of the subject matter of the invention in a schematic representation.
Es bezeichnen a einen Oberflächenkondensator, b dessen Luftabsaugestutzen und c die zu dem Strahlluftsauger d führende Luftabsaug@eleitung. An der in bezug auf den Luftabsaugestutzen höher gelegenen Stelle e der Leitung c ist .eine Einspritzdüse/ vorgesehen, welcher als Betriebsmittel Kondensat durch die Leitung g zugeführt wird. Damit eine Kondensation des durch die Luftabsa@ugeleitung hindurchgehenden Dampfes stattfinden kann, muß das in die Einspritzdüse j eingeführte Kondensat eine niedrigere Temperatur haben als diejenige, welche jeweils im Kondensator vorhanden ist. Zu diesem Zweck wird die Leitung g durch den Kühlwasserzuflußkanal hindurchgeführt. Um eine möglichst feine Verteilung des Einspritzwassers der Düse l zu gewährleisten, ist die Düse zweckmäßig mit einem Drall versehen.A denotes a surface condenser, b its air suction nozzle and c the air suction line leading to the jet air suction device d. At the related point e of line c is higher up on the air suction nozzle. provided, which is supplied as operating fluid condensate through line g. This results in condensation of the steam passing through the air suction line can take place, the condensate introduced into the injector j must be a lower one Temperature than that which is always present in the condenser. to for this purpose the line g is passed through the cooling water inflow channel. To ensure the finest possible distribution of the spray water from nozzle l, the nozzle is expediently provided with a swirl.
Das eingespritzte Kondensat läuft zusammen. mit dem durch Niederschlagen des Dampfes in der Luftabsaugeleitung gewonnenen Kondensat in den Kondensator und' wird von dort aus durch die Kondensatpumpe in den Speisewasserbehälter gefördert.The injected condensate converges. with that by knocking down condensate obtained from the steam in the air suction line into the condenser and ' is conveyed from there by the condensate pump into the feed water tank.
