Embodiment Construction

[0011] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0012] A sodium-air heat exchanger, which includes a cylinder 3, which is fixed on a concrete floor 10. An outlet damper 1 is provided at the top of the barrel 3, and an inlet damper 11 is provided at the bottom. The inlet damper 11 is a single-section inlet damper, and there are three arranged at an angle of 90° to each other to ensure that the air is evenly distributed according to the pipe system. The outlet damper 1 is a double-stage outlet damper. Each damper rotary guide vane can rotate and be fixed within the range of 0-90 degrees. An expansion tank 4 is arranged on the top of the inner cavity of the cylinder body 3, which is a vertical cylindrical container with a free surface of sodium, and is fixed on the inner side wall of the cylinder body 3 by a support plate. The top of the expansion tank 4 is provided with an argon inlet con...

Abstract

The invention discloses a heat exchanger for heat exchange between liquid sodium metal and air, comprising a cylinder, wherein, an outlet air door is arranged at the top of the cylinder, and an inlet air door is arranged at the bottom. The invention is characterized in that an expansion tank is arranged at the upper part of an intracavity of the cylinder; an argon gas inlet connection is arrangedat the top of the expansion tank, while the bottom is communicated with a sodium inlet pipe; the cylinder body is communicated with a heat exchange pipe bundle communicated with a sodium outlet pipe.The invention has the advantages that heat is taken away when air passes through the surface of heat exchange pipe bundle, enabling heat exchange between sodium and air; meanwhile, the chemical reaction between sodium and air is avoided due to inactivity.

Description

technical field [0001] The invention belongs to the technical field of heat exchangers, in particular to a heat exchanger technology for heat exchange between liquid metal sodium and air. Background technique [0002] The accident waste heat discharge system of the pool type sodium-cooled fast reactor is passive, and relies on natural circulation to take out the waste heat from the core under accident conditions. Usually, the heat exchanger used is a special heat exchanger, which can transfer the heat of the sodium in the intermediate circuit of the waste heat discharge system to the air, so as to cool down the sodium and realize natural circulation. The principle of the heat exchanger is relatively simple, which is to exchange heat through the reverse flow of two media. Usually the medium used is water or air, but there is no report on the heat exchanger technology between sodium and air in the open literature. Contents of the invention [0003] The object of the presen...
