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
The present invention relates to a kind of swirl combustion device, relate in particular to the swirl combustion device of a kind of metal and water reaction.
Background technique
At present, the reaction of active metal particle and water is introduced in underwater sailing body advancing means system.But the combustion efficiency of the firing unit of domestic traditional pressed engine is under water unsatisfactory, test can find there are many solid residues at engine interior.The main cause that causes this result is the generation of metallic oxide, is wrapped in surface of metal particles and has stoped burning to be proceeded.Traditional engine structure can not complete the catalytic combustion of water vapor and metal granule well, greatly reduces reactive rate, affects engine performance.
Summary of the invention
The object of the invention is that react mixing efficiency with water low in order to make up existing underwater engine metal, can not give full play to the shortcoming of its chemical property, and the swirl combustion device of a kind of metal and water reaction is provided.
The object of the present invention is achieved like this: comprise firing chamber, the upper part of firing chamber is that ring container, lower part are taper shape containers, described ring container comprises the upper cover of outer wall, inwall, connection inwall and outer wall and the bottom that inwall surrounds, ring container outer wall arranges metallic nozzle, ring container inner wall arranges water spray, the position of water spray is corresponding with the position of metallic nozzle, dock with the outer wall lower end of ring container on the top of taper shape container, and the bottom of taper shape container is connected with jet pipe.
The present invention also comprises some structure characteristics like this:
1. in taper shape container bottom, secondary-burning chamber is set, secondary combustion chamber outer wall arranges secondary injection water spray, and jet pipe is connected with the exit position of secondary-burning chamber.
2. described in, metallic nozzle and water spray are mass flow rate Control Nozzles or in metallic nozzle and water spray front end, mass flow controller are set.
3. have two described metallic nozzle and water spray at least.
4. described in, jet pipe is diverging shape.
Compared with prior art, the invention has the beneficial effects as follows: metallic dust of the present invention is carried by neutral gas, can be by regulating the inflow quality of nozzle flow control metallic dust; Metallic nozzle and water spray are arranged on same tangential relevant position, can make metallic dust and water reach the violent district of mixing reaction by the contact action that liquidates, the present invention not only can extend the holdup time of fuel in burner and extend metal and water reaction time, can also make metallic dust fuel fully mix fully and to react with water by the collision effect that liquidates.Percussion makes mutual collision friction between material, has destroyed and in course of reaction, has been formed on the patina of metal surface, further acutely burns with water thereby metallic region is come out, and strengthens its combustion characteristic.The lower part of firing chamber is cone, the convenient metallic dust not reacting enters secondary-burning chamber and burns again, at the top position of secondary-burning chamber, there is a secondary injection water hole, object is the mass flow rate of increasing export, make again imperfect combustion metallic dust fully react with the water that secondary injects, increase capacity usage ratio, thereby improve the capacity for work of fuel.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Case study on implementation one: in conjunction with Fig. 1, swirl combustion device of the present invention comprises firing chamber 3, the upper part of firing chamber 3 is ring containers, lower part is taper shape container, described ring container comprises outer wall, inwall, connect the upper cover 7 of inwall and outer wall and the bottom 8 that inwall surrounds, ring container outer wall arranges metallic nozzle 1, ring container inner wall arranges water spray 2, the position of water spray 2 is corresponding with the position of metallic nozzle 1, dock with the outer wall lower end of ring container on the top of taper shape container, the bottom of taper shape container is connected with jet pipe 5, jet pipe 5 is diverging shapes.Cyclotomy toroidal container upper end, described top is run through, and is also between inner and outer wall, to be provided with upper cover 7, and the intermediate gaps part that can surround in ring-shaped inner wall is to 2 li of injected waters of water spray.Metallic dust is carried and is entered ring container 3 by neutral gas from metallic nozzle 1, water drop enters ring container 3 by water spray 2, metal flow and current wash away mutually, in the interior violent mixing of ring container 3, and through igniter igniting ignite (not drawing igniter here).After lighting, the metallic dust mixing and water reaction are violent, produce a large amount of high-temperature fuel gas and metallic oxide, because metallic dust is to inject together with neutral gas, the material that metallic dust nozzle is injected than water spray is many, and speed is larger, after the effect of liquidating, vortex burner internal gas flow forms eddy current along metallic nozzle 1 inflow direction, and it is more abundant that this mixes metal and water, extends the reaction time simultaneously.Jet pipe 5 can make internal pressure of combustion chamber keep stable, and gas outlet speed is improved.
In implementation process of the present invention, can be corresponding at ring container outer wall, inwall multiple metallic nozzle 1 and water spray 2 be set, metallic dust and water can better be mixed.Described metallic nozzle 1 and water spray 2 are mass flow rate Control Nozzles or on metallic nozzle 1 and water spray 2, mass flow controller are set.
Case study on implementation two: according to the swirl combustion device described in case study on implementation one, in taper shape container bottom, secondary-burning chamber 4 is set, secondary-burning chamber 4 outer walls arrange secondary injection water spray 6, and jet pipe 5 is connected with the exit position of secondary-burning chamber 6.
The neutral gas after firing chamber reacts and water vapour drive the not metal granule of complete reaction to move to nozzle exit direction, first enter secondary-burning chamber 4, and a secondary injection water spray 6 is set at the top position of secondary-burning chamber 4, the metal granule of unreacted not complete reaction carries out secondary combustion with the water being injected by secondary injection water spray 6, energy utilization rate increases, also improved the acting ability of fuel, make metal and water reaction reach optimal proportion, increase capacity usage ratio, thereby improve the capacity for work of fuel, can obtain maximum combustion efficiency, can produce again maximum thrust.Secondary-burning chamber exports 4 positions and connects a jet pipe 5, can make burner internal pressure keep stable, and gas outlet speed is improved.
