Storage container

Abstract

The invention relates to a storage container (S) for storing a liquid with a storage space (SP) that is limited toward the bottom by a base (B) that is flat at least in places and an immersion pump (P) that is arranged in the storage space (SP), via which the stored liquid can be removed from the storage container (S). The base (B) of the storage space has a recess (V) in which the immersion pump is arranged and/or into which an intake pipe that is connected to the immersion pump extends.

1 . A storage container for storing a liquid comprising:
 a storage space defined at its bottom by a base that is flat at least in part, and   an immersion pump arranged within said storage space, via which stored liquid can be removed from said storage container,   said base having a recess in which (a) said immersion pump is arranged, and/or (b) an intake pipe connected to said immersion pump extends.   
     
     
         2 . The storage container according to  claim 1 , wherein the intake opening of said immersion pump and/or the end of said intake pipe located upstream of the immersion pump lies completely within said recess. 
     
     
         3 . The storage container according to  claim 1 , further comprising a movable separating element, with which the storage space can be separated into an upper partial space and a lower partial space. 
     
     
         4 . The storage container according to  claim 2 , further comprising a movable separating element, with which the storage space can be separated into an upper partial space and a lower partial space. 
     
     
         5 . The storage container according to  claim 1 , further comprising a salt melt is contained within said storage space. 
     
     
         6 . A liquid storage system comprising:
 a first storage container and a second storage container, said storage containers being separate from one another and thermally insulated against the environment,   a first set of pump and conduits for removing a liquid from the storage space of said first storage, delivering the liquid to a first heat exchanger coupled to solar absorber, removing the liquid from said heat exchanger, and delivering the liquid to the storage space of said second storage container, and   a second set of pump and conduits for removing liquid from the storage space of said second storage container, delivering the liquid to a second heat exchanger coupled coupled to a steam circuit of a steam turbine to produce water vapor, removing the liquid from said second heat exchanger, and delivering the liquid to the storage space of said first storage container,   wherein at least one of said first and second storage containers is a storage container according to  claim 1 .
