A kind of alkali metal seed injection device

Abstract

The invention relates to an alkali metal seed injection device. The device comprises an electric heater (1), an alkali metal injection pipe (2), an alkali metal storage tank (3), a gas-driven cycloneseparator (4), a liquid level monitoring sensor (5), a driving gas storage tank (6), a driving gas inlet pipe (7), a temperature and pressure monitoring and control device (9) and a mixed gas outlet pipeline (12); the alkali metal seed injection device is cylindrical; the side wall of the alkali metal seed injection device is of an interlayer structure; a cavity is formed between the inner wall and the outer wall of the interlayer; the electric heater (1) is located in the cavity; liquid alkali metal is injected into the gas-driven cyclone separator (4) and then is heated; a driving gas working medium is introduced to quickly atomize the alkali metal, and finally gasify the alkali metal; the liquid level monitoring sensor (5) monitors the gasification state of the liquid alkali metal; thetemperature and pressure monitoring and control device (9) controls the state of a mixed gas; and under the action of the driving gas working medium, the mixed gas outlet pipeline (12) is opened, so that the mixed working medium can be fed into a magnetofluid generator through a main gas flow pipeline (13) so as to be used for power generation.

Description

technical field [0001] The invention relates to the technical field of magnetic fluid power generation, in particular to an alkali metal seed injection device. Background technique [0002] Magnetic fluid power generation is a new power generation method that directly converts thermal energy into electrical energy, which began in the late 1950s. Its basic working principle is Faraday's law of electromagnetic induction. The difference from traditional power generation is that conductive fluid is used instead of conductive solid to conduct electricity, so that the conductive fluid working fluid passes through the magnetic field perpendicular to the flow direction at a certain speed, cuts the magnetic field lines and induces electromotive force, thereby generating electric energy. [0003] High-temperature gas magnetic fluid power generation is an important way. In order to obtain a sufficiently high conductivity of the high-temperature gas working fluid, it is necessary to i...

Problems solved by technology

At home and abroad, there are no reports in the literature on the use of gas-driven cyclone separators for alkali metal seed injection. Therefore, the development of gas-driven alkali metal seed injection devices is of great significance for improving the performance and practical application of this kind of magnetic fluid generator.
