Title:
HEAT EXTRACTION DEVICE OPERATING AT HIGH TEMPERATURE
Document Type and Number:
WIPO Patent Application WO2005064618
Kind Code:
A3
Abstract:
In the majority of heat or electricity production devices, of which nuclear reactors form a part, an exchange of heat between two circuits with either liquid or gas flows must be achieved. Tube heat exchangers are mainly used, in which tubes which run within one fluid, have a flow of the other fluid. In the case of high temperature reactors, said tubes are subject to corrosion and puncturing. The invention relates to a device for carrying out heat exchange and several reactor layouts optionally provided with devices for simple extraction of heat from said reactors. In the inventive embodiments, nuclear reactors are given, the device, however, is applicable to other technologies. The principle of the exchanger (10) is the injection of gas (9) into the liquid (8). The whole is mixed then separated by centrifugation, generated by one or several screws (12) and (48). The liquid (8) is recovered in a collector in the form of a torus (22) and the gas (9) by means of a diffuser (13).
