The outlet of several fused salts, the bore along the previous fused salt outlet in direction far from the fused salt entrance is less than the latter fused salt
The bore of outlet.
Further, the fused salt distribution rings (3) in annular shape, with the fused salt entrance be located at it is same diametrically described in
The bore of fused salt outlet is maximum.
Further, the 2/3 of a diameter of storage tank (1) diameter of the fused salt distribution rings (3).
Further, the number for hole being uniformly distributed along circumferential direction is 40-80.
Further, fused salt distribution rings (3) caliber is identical as the caliber of fused salt conduit (2).
Further, the fused salt conduit (2) extends along vertically downward direction.
Further, the ratio between the bore with the bore of the fused salt entrance of the fused salt outlet of maximum caliber are 1.5-4.
The utility model has the advantages that distribution consistency degree when can be effectively improved fused salt injection storage tank, is conducive to fused salt
Temperature Distribution is balanced, the accidents such as fused salt solidification even blocking pipeline caused by avoiding fused salt local temperature too low.
