Description

Phi.1

The invention relates to pump construction, in particular, to the design of a stage of an inkjet apparatus, and can be used in the design of hydrotransport systems for general industrial purposes.

The purpose of the invention is to increase efficiency and reduce size by increasing the intensity of heat transfer.

FIG. 1 schematically shows the stage of the jet apparatus, a longitudinal section; in fig. 2 - capacitor, longitudinal section; in fig. 3 is a section A-A in FIG. 2; in fig. 4 - condenser with a streamlined body, a longitudinal section.

The jet apparatus stage contains an active nozzle 1, a mixing chamber 2, a diffuser 3 and a condenser made in the form of a tapered pipe 4 and equipped with a pressure and drain lines 5 and 6 of the condensing liquid. The stage is provided with annular inlet and outlet manifolds 7 and 8, communicated respectively with inlet and outlet lines 5 and 6, and with a backing spatula 9, in the inlet section of the pipe 4 are tangentially directed holes 10, its outlet section is provided an annular extension 11, and a manifold 8 of the outlet is installed on the outlet section of the pipe 4 to form an annular slot 12 with the inner surface of the annular expansion 11, wherein the collectors 7 and 8 are supplied and discharged to the cavity of the pipe 4, respectively m said holes 10 and slits 12 and spun ml yuschy apparatus 9 is installed behind the annular expander 11 (Figures 1-3). The stage can be provided with a streamlined body 13 located along the axis of the pipe 4, and flat pylons 14, by means of which the spatula blade 9 and the body 13 are fixed in the pipe 4 (figure 4). Behind the proposed stage, any other level of the jet apparatus 15 can be installed.

Stage jet apparatus operates as follows

In the mixing chamber 2, the ejected gas is mixed with the ejecting water vapor and compressed at the outlet. The vapor-gas mixture enters the narrowing pipe 4. From the pressure line 5, jets of cooling water are injected through the manifold 7 and the opening 10.

which spin the flow and cool the gas-vapor mixture. In this case, most of the steam condenses. Under the effect of a twist, the condensed liquid is thrown onto the inner surface of the tapered pipe 4 and moves towards the outlet side. When it enters the annular slot 12, water is drained into the collector 8 of the outlet, from here it enters the drain line 6. The liquid layer in the annular expansion of the pipe 4 does not allow gas bubbles to enter the collector 8. The vapor – gas mixture, freed from condensate, flows around the spraying blade apparatus 9 and receives the axial flow direction.

When installing the streamlined body 13, the flow of the vapor gas, the passage of the capacitor, made in the form of a tapered pipe 4, flows around the body 13 and twists on its surface. The fluid particles throughout the flow section receive an additional twist, which is necessary to drop the liquid phase on the wall of the pipe 4.

The exit from the narrowing pipe 4, the vapor-gas mixture enters the next stage 15 of the apparatus and is compressed therein to the design pressure.
