Description
Technical field
The present invention relates to a kind of metal dust fuel supply device that is applied to metal and water reaction system.
Background technology
At present, produce high-temperature gas by water with the combustion gas reaction of being rich in the active metal particle, and then, caused people's attention through spraying the combustion mechanism of larynx or turbine installation acting.But to the research in this field, still brand-new problem at home, some key technologies do not obtain fine solution as yet like the water intake mode of the organizational form of burning, propulsion system and quantity delivered distribution etc.The Traditional engine structure can not be accomplished the blending process of water vapour and combustion gas well, greatly reduces reaction rate, influences engine performance.Water vapour is mixed with fuel gas high efficiency, give full play to its chemical property, discharging high-energy in the short time is a bottleneck of current this system research.
Summary of the invention
The object of the present invention is to provide a kind of metal dust fuel that can make to carry out sufficient fluidisation and preheating, efficient, reliable, little metal dust fuel supply device to the ablation of breather line.
The objective of the invention is to realize like this:
Metal dust powder column 2 and piston and transmission component 1 are set in metal dust powder column storehouse; Piston and transmission component 1 are in metal dust powder column 2 rear ends; Piston and transmission component 1 are by motor-driven, and metal dust powder column storehouse is other to be provided with gas generator 3, and the powder column that incendivity generates high-temperature fuel gas is housed in the gas generator 3; Gas generator 3 front ends are equipped with igniter 4; The outside blast tubes 5 that connect of gas generator 3, metal dust powder column storehouse front end is provided with fluidising chamber 8, is connected with toroidal nozzle 7 by annular air collecting chamber 6 between blast tube 5 and the fluidising chamber 8.
Piston and transmission component 1 end face are conical, and said conical cone angle is identical with the jet angle of nozzle ring 7.
Annular air collecting chamber 6 adopts high temperature ceramic material to process one with nozzle ring 7.
The method that the present invention adopts slit to blow powder realizes the supply of metal dust fuel, and piston promotes the feeding of metal dust powder column, and the metal dust powder column carries out fluidisation and preheating under the effect of the high-temperature fuel gas that gas generator produced.Existing metal dust feeding mechanism powder charge metal dust content is low in order to remedy, the shortcoming of fluid effect difference; The present invention has designed a kind of metal powder fuel supply device; Not only can make metal dust fuel carry out sufficient fluidisation and preheating, can also adjust metal dust flow fuel and fluid effect through the feed speed of regulating piston and the jet angle of nozzle ring.
The main points of the technical scheme that the present invention adopted are: in metal dust fuel rear end conical piston is set, promotes the metal dust powder column and realize feeding.At the other gas generator of establishing in addition of metal powder column, high-temperature fuel gas is through annular air collecting chamber, after in nozzle ring, quickening to the metal dust powder column cut, fluidisation and preheating, strengthen its combustion characteristics.
Metal dust carries out fluidisation and preheating through the mode that slit blows powder, improves combustibility, can adopt pure metal powder as the powder column material, has realized the maximization of metal filling ratio.The piston cone angle is identical with the nozzle ring spray angle, has avoided the appearance of surplus medicine phenomenon.Annular air collecting chamber and nozzle ring adopt high temperature ceramic material integral body to process, and when high-temperature fuel gas is quickened, avoid the ablated destruction of device.
The invention has the beneficial effects as follows: the piston cone angle is provided with rationally, has avoided the appearance of surplus medicine phenomenon; Powder column adopts all-metal powder powder column, and metal filled ratio is big; The feeding of powder column is controlled by piston, can be through regulating piston control metal dust flow fuel; The metal dust powder column cuts fluidisation by high-temperature fuel gas, can control the fluidization quality of metal dust fuel through the angle of regulating nozzle ring.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the cut-away view of annular air collecting chamber and nozzle ring.
The specific embodiment
In conjunction with accompanying drawing the present invention is further specified:
In conjunction with Fig. 1, piston and transmission component 1 are arranged on metal dust powder column 2 rear ends, and piston and transmission component 1 move forward under the driving of motor, promote metal dust powder column 2 march forward to.A gas generator 3 is established on metal dust powder column 2 sides in addition, in the gas generator 3 powder column is housed, and incendivity generates high-temperature fuel gas.Gas generator 3 front ends are equipped with igniter 4, and after igniter 4 igniting, gas generator 3 is started working.The outside blast tubes 5 that connect of gas generator 3 are connected with toroidal nozzle 7 by annular air collecting chamber 6 between blast tube 5 and the fluidising chamber 8.When device is started working, igniter 4 igniting, gas generator 3 is started working, and produces a large amount of high-temperature fuel gas, and high-temperature fuel gas enters into annular air collecting chamber 6 through gas pipeline 5, and annular air collecting chamber 6 temporarily stored-gas is nozzle ring 7 air feed also.High-temperature fuel gas quickens in nozzle ring 7, forms the gas-flow of high temperature and high speed, spurts in the fluidising chamber 8.At this moment, metal dust powder column 2 under the promotion of piston and transmission component 1, feeding in fluidising chamber 8, metal dust powder column 2 is fluidized under the shear action of high temperature and high speed gas-flow, and obtains preheating, gets into subsequently and participates in burning in the combustion chamber of engine.Piston and transmission component 1 end face adopt conical design, and its cone angle is identical with nozzle ring 7 jet angles.Annular air collecting chamber 6 is done as a whole the manufacturing with nozzle ring 7, and material is a high temperature ceramic material.
Fig. 2 is the internal structure of annular air collecting chamber 6 and toroidal nozzle 7.During device work, high-temperature fuel gas temporarily stores in annular air collecting chamber 6, and in nozzle ring 7, quickens, and gets in the fluidising chamber subsequently.Sealing ring 9 can prevent causing in the process of locking apparatus work the leakage of combustion gas.
