Abstract
The utility model provides a novel steam ejector, and belongs to the field of ejectors. The novel steam ejector comprises a suction chamber, a mixing chamber and a diffusion pipe, and is characterized in that the front end of the suction chamber is connected with a Venturi tube of the mixing chamber, the diffusion pipe is disposed on the Venturi tube and extends outward to form a micro-cone shape, the suction chamber is symmetrically provided with suction pipes which are arranged on the suction chamber obliquely, and a Laval nozzle is arranged in the suction chamber. The novel steam ejector is high in suction capacity and wide in work range, enters a portion obliquely, can be sucked in a Laval nozzle negative pressure area through working steam more easily, increases the flow of ejected steam, improves an ejection coefficient, reduces pressure of the ejected steam, and improves ejector efficiency; the suction pipes are symmetrically arranged, so that the pressure of the ejected steam in the negative pressure area is uniform, pressure losses are reduced, and the flow of the ejected steam is increased. The novel steam ejector is simple and reasonable in structure, ingenious and novel in idea, and easy to popularize and use on a large scale.
Description
Technical field:
The utility model belongs to ejector field, and what be specifically related to is a kind of Steam injector.
Background technique:
Ejector is to utilize the ejector action of one high pressure, high-octane flow type pump with injection to suck the device of another burst of low pressure, low-yield fluid, in many places, all will use ejector.At present, for traditional ejector, sparger mass ratio of induced-to-inducing air is on the low side, and the pressure that reclaims low pressure steam is higher, quantity is less than normal, and efficiency is on the low side.Steam turbine exhaust steam injection rate as very low in some pressure is just too low, thereby makes fluid pump structure become complicated.
Model utility content:
In order to overcome the deficiency in background technique, the utility model provides a kind of Steam injector.
The utility model solves the technological scheme that its technical problem adopts: this Steam injector, comprise suction chamber, mixing chamber, diffusing tube, it is characterized in that: suction chamber front end connects the Venturi tube of mixing chamber, Venturi tube is provided with diffusing tube, and expanding pipe is abducent micro-taper, on suction chamber, be arranged with suction pipe, and suction pipe is inclined on suction chamber, in suction chamber, is provided with La Faer nozzle.
The beneficial effects of the utility model are: suction capactity is large, and operating range is wide, and inclination enters, more easily by working steam, in Laval-cavity nozzle negative pressuren zone, entrainmented, increase jetting steam caused flow, improve mass ratio of induced-to-inducing air, reduce jetting steam caused pressure, improve ejector efficiency; Suction pipe is symmetrical arranged and makes the jetting steam caused pressure of negative pressuren zone even, reduces the pressure loss, increases jetting steam caused flow.Simple and reasonable, the novelty that is skillfully constructed, is easy to large-scale promotion application.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, this Steam injector, comprise suction chamber 1, mixing chamber 4, diffusing tube 5, it is characterized in that: suction chamber 1 front end connects the Venturi tube of mixing chamber 4, Venturi tube is provided with diffusing tube 5, and expanding pipe 5 is abducent micro-taper, is arranged with suction pipe 2 on suction chamber 1, and suction pipe 2 is inclined on suction chamber 1, is provided with La Faer nozzle 3 in suction chamber 1.Utilize the principle of dynamics that the mobile static energy of fluid and kinetic energy are changed mutually to form suction force.The water vapour with certain pressure, throat by La Faer nozzle 3 reaches the velocity of sound, while arriving the diffusing tube of La Faer nozzle 3, static energy is all converted into kinetic energy, reach ultrasound velocity, in La Faer nozzle 3 outlet ports, form vacuum, the low-pressure water steam being sucked is under the effect of pressure reduction, be drawn into suction chamber 1, enter in Venturi tube mixing chamber 4 while mixing with ultrasonic steam, then with subsonic speed, 5 ejections of the diffusing tube Venturi tube form the steam between working steam parameter and jetting steam caused parameter again.It is exactly briefly the special device that improves low pressure steam pressure, by high pressure steam, spray the high velocity air of generation by low pressure steam or condensed water flashing steam pressure and temperature raising, and the pressure and temperature of high pressure steam reduces, thereby the pressure and temperature that makes low pressure steam is brought up to the index of manufacturing technique requirent, reach energy-conservation object.
The utility model suction capactity is large, and operating range is wide, and suction pipe is symmetrical arranged, tilt to enter suction chamber, more easily by working steam, in Laval-cavity nozzle 3 negative pressuren zones, entrainmented, increase jetting steam caused flow, improve mass ratio of induced-to-inducing air, reduce jetting steam caused pressure, improve ejector efficiency; Suction pipe 2 is symmetrical arranged and makes the jetting steam caused pressure of negative pressuren zone even, reduces the pressure loss, increases jetting steam caused flow.Simple and reasonable, the novelty that is skillfully constructed, is easy to large-scale promotion application.
