A vortex combustion device for metal and water reaction

Abstract

The invention provides a swirl combustion device for metal and water reaction. The swirl combustion device for metal and water reaction comprises a combustion chamber, wherein the upper portion of the combustion chamber is an annular container, and the lower portion of the combustion chamber is a conical container. The annular container comprises an outer wall, an inner wall, an upper cover and a bottom cover, wherein the upper cover is used for connecting the inner wall and the outer wall, and the bottom cover is surrounded by the inner wall. A metal spray nozzle is arranged on the outer wall of the annular container, a water spray nozzle is arranged on the inner wall of the annular container, the position of the water spray nozzle corresponds to that of the metal spray nozzle, the upper portion of the conical container is in butt joint with the lower end of the outer wall of the annular container, and the bottom of the conical container is connected with a spray pipe. The swirl combustion device for metal and water reaction is simple in structure and reliable and can overcome the defect that because a compact oxidation film is formed on the surface of metal, combustion is affected; the diameter of molten metal liquid drops can be continuously reduced through shear force of swirls, the surface of unreacted metal is exposed so that the metal can react with water, and thus the metal and water reaction can go on stably, and the combustion efficiency of metal is improved.

Description

Technical field [0001] The invention relates to a vortex combustion device, in particular to a vortex combustion device in which metal and water react. Background technique [0002] At present, the reaction of active metal particles and water is introduced into the propulsion system of underwater vehicles. However, the combustion efficiency of the combustion device of the traditional domestic underwater ramjet is not ideal. The test can find that there are many solid residues inside the engine. The main reason for this result is the production of metal oxides, which wrap on the surface of the metal particles to prevent the combustion from continuing. The traditional engine structure cannot well complete the contact combustion of water vapor and metal particles, which greatly reduces the reaction rate and affects the engine performance. Summary of the invention [0003] The purpose of the present invention is to make up for the disadvantages of the low mixing efficiency of metal ...
