Detailed description of the invention
A kind of issuance of materials device air conveying for granular solid, including connecting as one
Gases at high pressure spray into pipe 1, solid feed opening 2, gas-solid mixing room 3 and gas-solid two
Mixing bleed pipe 4 mutually.Described gases at high pressure spray into pipe 1, gas-solid mixing room 3 and gas
Gu biphase bleed pipe 4 is on same central axis, gas-solid mixing room 3 is formed at height
Body of calming the anger sprays between pipe 1 and gas-particle two-phase bleed pipe 4, and solid feed opening 2 is positioned at
The top of gas-solid mixing room 3, gas-solid mixing room 3 spray into gases at high pressure respectively pipe 1,
Solid feed opening 2 and gas-particle two-phase bleed pipe 4 communicate.Described gases at high pressure spray into pipe
1 is tapering type, and described gas-particle two-phase mixing bleed pipe 4 is gradual-enlargement type.
Laval nozzle is to be made up of two conical pipes, before the first stage for shrink
Pipe, after second stage for expansion pipe.In the first stage, gasmovement is followed " flows
When body moves in pipe, little place, cross section flow velocity is big, and cross section general goal flow velocity is little " principle,
Therefore air-flow constantly accelerates.When arriving narrow larynx, flow velocity has been over velocity of sound.And
Transonic fluid is the most no longer followed when motion, and " greatly, cross section is big for little place, cross section flow velocity
Place's flow velocity is little " principle, but on the contrary, cross section is the biggest, flow velocity is the fastest, therefore,
In second stage, the speed of combustion gas stream is further accelerated, for 2-3 kilometer per second,
Be equivalent to 7-8 times of velocity of sound, this creates the terminal huge thrust.Laval nozzle
Actually serve the effect of " flow velocity enhancer ".
