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, by water and the combustion gas reaction and the generation high-temperature gas that are rich in active metal particle, and then the combustion mechanism doing work by spray larynx or turbine installation, caused people's attention.But the research to this field, at home or a brand-new problem, some key technologies, as the water intake mode of the organizational form of burning, propulsion system and quantity delivered distribution etc. not yet obtain fine solution.Traditional engine structure can not complete the blending process of water vapour and combustion gas well, greatly reduces reaction rate, affects engine performance.Water vapour is mixed with fuel gas high efficiency, give full play to its chemical property, in the short time, discharging high-energy 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 to the ablation of breather line metal dust fuel supply device.
The object of the present invention is achieved 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 driven by motor, the other gas generator 3 that is provided with in metal dust powder column storehouse, the powder column that incendivity generates high-temperature fuel gas is housed in gas generator 3, gas generator 3 front ends are equipped with igniter 4, the outside blast tube 5 that connects of gas generator 3, metal dust powder column storehouse front end arranges fluidising chamber 8, between blast tube 5 and fluidising chamber 8, by annular air collecting chamber 6, is connected with toroidal nozzle 7.
Piston and transmission component 1 end face are conical, and described conical cone angle is identical with the jet angle of nozzle ring 7.
Annular air collecting chamber 6 adopts high temperature ceramic material to make 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, carries out fluidisation and preheating under the effect of the high-temperature fuel gas that metal dust powder column produces at gas generator.For making up the shortcoming that existing metal dust feeding mechanism powder charge metal dust content is low, fluid effect is poor, 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 by the feed speed of regulating piston and the jet angle of nozzle ring flow and the fluid effect of metal dust fuel.
The main points of the technical solution adopted in the present invention are: in metal dust fuel rear end, conical piston is set, promotes metal dust powder column and realize feeding.At the other gas generator of separately establishing of metal powder column, high-temperature fuel gas is through annular air collecting chamber, after accelerating in nozzle ring to metal dust powder column cut, fluidisation and preheating, strengthen its combustion characteristics.
The mode that metal dust blows powder by slit is carried out fluidisation and preheating, improves combustibility, can adopt pure metal powder as powder column material, has realized the maximization of metal filling ratio.Piston cone angle is identical with 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 make, and avoid the ablated destruction of device when high-temperature fuel gas is accelerated.
The invention has the beneficial effects as follows: piston cone angle arranges rationally, avoided the appearance of surplus medicine phenomenon; Powder column adopts all-metal powder powder column, and metal filled ratio is large; The feeding of powder column is controlled by piston, can control by regulating piston the flow of metal dust fuel; Metal dust powder column cuts fluidisation by high-temperature fuel gas, can be by regulating the angle of nozzle ring to control the fluidization quality of metal dust fuel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the cut-away view of annular air collecting chamber and nozzle ring.
The specific embodiment
The present invention will be further described by reference to the accompanying drawings:
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.Metal dust powder column 2 is other separately establishes a gas generator 3, in 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 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 by gas pipeline 5, and annular air collecting chamber 6 temporarily stored-gas is also nozzle ring 7 air feed.High-temperature fuel gas accelerates in nozzle ring 7, forms the gas-flow of high temperature and high speed, spurts in fluidising chamber 8.Now, metal dust powder column 2 is under the promotion of piston and transmission component 1, and to 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, enters subsequently in the combustion chamber of engine and participates in burning.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 manufacture with nozzle ring 7, and material is 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 accelerates in nozzle ring 7, enters in fluidising chamber subsequently.Sealing ring 9 causes the leakage of combustion gas in can the process of anti-locking apparatus work.
