Device for a heat recovery for high temperature steel

The utility model provides a device for a heat recovery for high temperature steel, it includes: a plurality of heat exchange tubes set up towards the high temperature steel, ascending collector, one end communicates in the one end of each heat exchange tube, the water of ormal weight is deposited in advance to the steam pocket, communicates in the other end of the collector that rises, has steam outlet, and the decline collector, one end feeds through in the steam pocket and the other end feeds through in the other end of each heat exchange tube water in the steam pocket gets into each heat exchange tube via the decline collector, and the water and the high temperature steel of each heat exchange tube of flowing through carry out the heat exchange, and hyperthermia radiation heat is emitted and the cooling to the high temperature steel, the heat of water uptake high temperature steel radiation and the evaporation that intensifies, and then form the soda mixture, and the soda mixture is discharged after in carrying the steam pocket by the collector that rises, the steam in the steam pocket in the soda mixture is discharged and is used for follow-up utilization via steam outlet from each heat exchange tube, and the water in the soda mixture is assembled in the steam pocket to it recycles to infeed the decline collector. From this, can retrieve the heat energy of high temperature steel
