Abstract

The invention can be used to exhaust air from steam turbine condensers. The aim of the invention is to increase efficiency. The displacement chamber 4 is equipped with tangential nozzles dp for supplying the active medium, and at its outlet there is a diaphragm 8. The diffuser 5 and the discharge nozzle 6 are annular and in the latter the flow spinning blades 9 are installed. gets a rotational movement with the formation of a free surface. Another part of the flow, the passage through the active nozzle 2 and the swirling element 3, expires in the form of droplets, which bombard the main flow and capture the gaseous passive medium. In the nozzle, 6, the rotational movement of the flow is converted to rectilinear. 4 il. with S SL SA O SP 4 iu: l

Description

jet technology, mainly to water-air ejectors for exhausting air from steam turbine condensers.

The aim of the invention is to increase efficiency.

Figure 1 presents the described jet apparatus, a longitudinal section; figure 2 is a section a - a in figure 1; Fig. 3 a section on fig. one ; Fig, 4 section bb In figure 1,

Inkjet machine contains receiving

In the discharge nozzle 6 by means of the blades 9 rotational movement of the flowmeter 1, the active 15 placed in it flows into the annular diffuser 5, the pressure nozzle 2 with the swirling element 3, the nozzle 6 and expires from the mixing chamber 4, the diffuser 5 and the that porn connection pipe 6. Mixing chamber 4 is equipped with tangential connections

The 7th active medium supply and the location of the 20 ka is converted into a straight line, at the outlet of the mixing chamber 4

Claims (1)

diaphragm 8, and the diffuser 5 and head ™ The formula of the invention Ny nozzle 6 is made annular. 8 pressure pipe 6 installed spin the thread blades 9, The main flow of the liquid active medium HjH3Koro through the tangential nozzles 7 is fed into the mixing chamber 4, where it receives rotational movement with the formation of the free surface. In this case, the central part of the mixing chamber 4 is filled with an air-vapor mixture. Further. The flow of active medium is poured through the diaphragm 8 into the annular diffuser 5 and completely fills it. Inkjet apparatus, mainly 25 vapor-air ejector, containing a receiving chamber, an active nozzle placed in it with a twisting 1M element, a mixing chamber, a diffuser and a discharge nozzle, differ in ayu-: 10 y and in order to increase efficiency , the mixing chamber is equipped with tangential nozzles for supplying the active medium and a diaphragm located at the outlet of the mixing chamber, 35 and the diffuser and the discharge nozzle are annular. bone active medium (3-10% of the flow rate) with a high pressure is fed through the active nozzle 2 and twisting element 3 and expires from the active nozzle 2 in the form of a stream of liquid droplets. In this case, liquid droplets bombard the main flow of the active medium at the place of its transfusion through aperture 8 and capture along with a gaseous passive medium entering the jet apparatus from the receiving chamber 1. Next, the gas-liquid flow postuV of the discharge nozzle 6 using the blades 9 rotates the movement into the annular diffuser 5, the pressure nozzle 6 and flows out of the apparatus. Inkjet apparatus, mainly 25 vapor-air ejector, containing a receiving chamber, an active nozzle placed in it with a twisting 1M element, a mixing chamber, a diffuser and a discharge nozzle, differ in ayu-: 10 y and in order to increase efficiency , the mixing chamber is equipped with tangential nozzles for supplying the active medium and a diaphragm located at the outlet of the mixing chamber, 35 and the diffuser and the discharge nozzle are annular. 5 B A a FIG. 2 in a niche Order 1414/35 Circulation 575 Production polygr, np-THe.j, Uzhgorod, st.
