120 DEG C of working fluid-high steam from boiler drum is by nozzle A, by steam pipe 10 and nozzle 6
Into in receiving chamber, high steam is realized that adiabatic expansion, pressure energy are converted into kinetic energy, is steamed with high speed fluidised form under the effect of nozzle 6
Vapour leaves nozzle 6, Confined space jet is formed in receiving chamber, and export regional area in nozzle 6 and form jet stream low-pressure area,
Under low-pressure area swabbing action, about 300 DEG C of driving fluid-low-pressure tail gas from ground flue are multi-direction by tail gas mouth B1 and B2
Fair current state enters receiving chamber, is swept along by high velocity vapor, under turbulent vortex and component diffusion double action, steam and tail gas production
Raw energy exchange, high velocity vapor speed and pressure reduce, and the speed and pressure of tail gas get a promotion.
As flow field is developed, the mixed flow of high velocity vapor and low-pressure steam formation enters 4 region of inner cone, in inner cone 4 without cunning
It moves under wall action, jet flow is affected by local restriction, the middle rear end flow development of jet stream, avoids local return
It generates, forms more stable and uniform basic flow fluidised form, while tail gas and steam carry out strong energy exchange, formed preliminary
Mixed flow reaches first mixed effect.Later, mixed flow enters the front end Taper Pipe 3 in the middle part of mixing chamber, further completes energy and hands over
It changes, progress is secondary mixed intensified, and completion is sufficiently mixed process, obtains pressure and speed is uniform, the pipe stream gaseous mixture of fluid stable.
Then, gaseous mixture enters 1 in the rear end Taper Pipe of diffusion room, along with the increase of 1 actual internal area of rear end Taper Pipe, mixes
It closes pneumatic energy and is converted into pressure energy, speed reduces, and pressure improves, and finally leaves steam jet ejector with the state higher than tail gas pressure
Into the further heat temperature raising of regenerative chamber.
The utility model has following technical characteristic：
1, inclination angle is designed：Water conservancy diversion drag reduction is convenient for suction of the steam jet low-pressure area to tail gas, fair current to enter in receiving chamber,
Keep high steam and tail gas mixed process softer, DIRECT ENERGY caused by hard hit between fluid when reducing preliminary mixing
Loss.
2, more mouthfuls of injections：Tail gas enters receiving chamber by 2 to 3 mouths, compared with unilateral injection, avoids internal bias current, flowing
Dead zone is generated with a wide range of vortex, is made to receive Indoor Flow Field uniformly, steadily, is avoided in dead zone in dust deposit and secondary flow, region
Vortex dissipates.
3, inner cone designs：Appropriate limitation is carried out about to the middle rear end flow development region of the Confined space jet of high steam
Beam, the flow field in stationary flow core area reduce jet stream recirculating zone range, improve distribution of shock-wave, and vortex and shock wave is avoided to dissipate；It realizes and steams
Vapour and the mixed first rectification of tail gas keep internal flow more steady, improve injector pair in conjunction with the secondary rectification of mixing chamber
The adaptability of working steam pressure fluctuation.
4, injector is compact-sized reasonable：The jet action for having played steam to greatest extent, makes high steam and tail gas
Injection-mixed flow process tend to mitigate, reduce internal sinuous flow and flowing bottleneck, reduce energy dissipation, increase injection
The ejector capacity of device improves the working efficiency of injector.
5, separate structure:Compared with traditional integral structure, Split bolt-screw thread-inlay card connection structure is convenient for setting
Standby manufacture and installation, component can be used the molding of casting method fission, reduce production cost；Easy to disassemble simultaneously and adherency dust and dirt
It removes.
The content of the utility model is not limited to cited by embodiment, and those of ordinary skill in the art are new by reading this practicality
Type specification and to any equivalent transformation that technical solutions of the utility model are taken, be the claim institute of the utility model
Cover.
