als Speisewasserreserve gesammelt wird.
Dieses erfindungsgemässe Verfahren ist bei einer Ausführungsart einer Kesselspeisewasser- und Kon-

bzw.angeordneten Mischbettfilter, dem ein Anschwemmfilter vorgeschaltet sein kann, wobei die erfindungsgemässe Anlage dadurch gekennzeichnet ist, dass im Einlauf des Mischbettfilters neben der Kondensatrückleitung noch eine Verbindungsleitung zum Auslauf der Entkarbonisierungs- bzw. KesselspeisewasserVollentsalzungs-Anlage mit einem Wechselventil anschliessbar ist und der Mischbettfilterauslauf je eine ebenfalls im einen Wechselventil schaltbare Verbindungsleitung zum Kessel und einem zugeordneten Sammelbehälter besitzt, der seinerseits über eine Pumpenleitung mit der Regenerierleitung der Kesselspeisewasser-Vollentsalzungs-Anlage bzw. direkt mit der Kesselwassereinspeiseleitung verbunden ist.
Dadurch, dass die Kesselspeisewasser-Vollentsalzungs-Anlage nicht auch noch das zu ihrer Regeneration notwendige Wasser aufbringen muss, kann diese kleiner ausgelegt werden. Sollte sie einmal gänzlich ausfallen, so kann der Kessel kurzfristig über die umschaltbare Kondensatentsalzung oder aus deren Sammelbehälter versorgt werden.
PATENTANSPRÜCHE :
1. Verfahren zur Kondensatvollentsalzung bei Dampfkraftanlagen (Turbinenkondensat) im Wege des Ionenaustausches in einem Mischbettfilter, dem ein Anschwemmfilter vorgeschaltet sein kann, dadurch gekennzeichnet, dass das Mischbettfilter nur zu einem Bruchteil seiner Durchbruchska- pazität mit Kondensat und anschliessend bis zur Erschöpfung mit von Kationen oder Karbonaten befreitem Wasser der Kesselspeisewasser-Anlage beschickt und das hiebei gewonnene vollentsalzte Wasser zur Regeneration der Kesselspeisewasser-Vollentsalzungs-Anlage und/oder als Speisewasserreserve gesammelt wird.

is collected as a feed water reserve.
This inventive method is in one embodiment of a boiler feed water and con
EMI2.1
or arranged mixed-bed filter, which can be preceded by a precoat filter, the system according to the invention being characterized in that in the inlet of the mixed-bed filter, in addition to the condensate return line, a connecting line to the outlet of the decarbonization or boiler feed-water desalination system can be connected with a changeover valve and the mixed-bed filter outlet can be connected has a connection line to the boiler and an associated collecting tank, which can also be switched in a shuttle valve, which in turn is connected via a pump line to the regeneration line of the boiler feed water demineralization system or directly to the boiler water feed line.
Because the boiler feed water demineralisation system does not also have to apply the water required for its regeneration, it can be designed to be smaller. If it should fail completely, the boiler can be supplied for a short time via the switchable condensate desalination or from its collecting tank.
PATENT CLAIMS:
1. A method for the complete desalination of condensate in steam power plants (turbine condensate) by way of ion exchange in a mixed bed filter, which can be preceded by a precoat filter, characterized in that the mixed bed filter only contains a fraction of its breakthrough capacity with condensate and then until it is exhausted with cations or Carbonate-free water of the boiler feed water system is charged and the fully desalinated water obtained is collected for regeneration of the boiler feed water complete desalination system and / or as a feed water reserve.
