Abstract

FIELD: machine building.
SUBSTANCE: centrifugal vortex burner consists of case with vortex chamber and nozzle. The case is made in form of a supplying connecting pipe with an orifice for supply of liquid from a main and a cylinder bush sleeve with external thread coaxially connected to it. Also, a nozzle is connected coaxially to the case in its lower part by means of the bush sleeve with internal thread. The nozzle is made in form of centrifugal vortex of liquid flow in form of a blind cylinder insertion with at least three tangential inputs in form of cylinder orifices. The bush sleeve is a part of the nozzle and is set coaxially and axially relative to centrifugal vortex. A conic orifice is made in end surface of the centrifugal vortex. This orifice is coaxial to the blind cylinder insertion of the vortex installed in the cylinder chamber of the case forming a circular cylinder chamber for supply of liquid to tangential inputs of the centrifugal vortex. The tangential inputs are made as channels tangentially arranged to internal surface of the blind cylinder insertion. An intensifier of flow rotation is installed in the centrifugal vortex. The intensifier corresponds to a rod one end of which is secured to blind round surface of the cylinder insertion of the vortex by means of a screw, while on another end of it there is mounted the second flow vortex made as a bush with screw external thread of a big pitch of a trapezoidal profile and secured by means of internal thread to the rod with a faring of a conic shape.
EFFECT: raised efficiency of spraying by increased spray.

Description

The invention relates to means for spraying liquids, solutions.

The closest technical solution to the claimed object is the nozzle on.with. USSR No. 306270, F02C 7/24 from 04.01.70., Comprising a housing with a swirl chamber and a nozzle insert (prototype).

A disadvantage of the known nozzle is that it does not provide a wide spray pattern.

The technical result is an increase in spraying efficiency by increasing the spray pattern.

This is achieved by the fact that in a centrifugal vortex nozzle containing a casing with a swirl chamber and a nozzle, the casing is made in the form of a supply fitting with an opening for supplying fluid from the line and a cylindrical sleeve coaxially connected to it with an external thread, while coaxially to the casing in its lower part a nozzle made in the form of a centrifugal swirl of a fluid flow in the form of a blind cylindrical insert with at least three tangential inlets in the form of cylindrical holes, while the sleeve is part of the nozzle and mounted coaxially and coaxially with respect to the centrifugal swirler, and in the end surface of the centrifugal swirler a conical hole is made coaxial with the blind cylindrical insert of the swirl, which is installed in the cylindrical chamber of the casing with the formation of an annular cylindrical chamber for supplying liquid to tangential entries of a centrifugal swirl, and tangential entries made in the form of channels tangentially located to the inner surface and a blind cylindrical insert, and in the centrifugal swirler a fluid flow twist intensifier is installed, which is made in the form of a rod, one end of which is fixed to the blind round surface of the cylindrical swirl insert, using a screw, and on the other end of which a second flow swirl made in the form of a sleeve is mounted with external screw thread with a large pitch of a trapezoidal profile and fixed by means of an internal thread on a rod with a cone-shaped cowl.

Figure 1 presents a diagram of a centrifugal vortex nozzle, figure 2 is a section aa of figure 1.

The centrifugal vortex nozzle (figure 1) includes a housing 1, which is made in the form of a supply fitting with an opening for supplying fluid from the line and a cylindrical sleeve 2 coaxially connected to it with an external thread 3.

Coaxially to the housing 1 in its lower part is connected by means of a sleeve 4 with an internal thread a nozzle 5 made in the form of a centrifugal swirl 6 of a fluid flow in the form of a blind cylindrical insert with at least three tangential inlets 13 in the form of cylindrical holes (Fig. 2). The sleeve 4 is part of the nozzle 5 and is mounted coaxially and coaxially with respect to the centrifugal swirler 6. In the end surface of the centrifugal swirler 6 there is a conical hole 8, coaxial to the blind cylindrical insert of the swirler 6.

A centrifugal swirl 6 is installed in the cylindrical chamber 9 of the housing with the formation of an annular cylindrical chamber 7 for supplying fluid to the tangential inlets 13 of the centrifugal swirl 6, and the tangential inlets 13 are made in the form of channels tangentially located to the inner surface of the blind cylindrical insert.

In the centrifugal swirler 6, a fluid flow twist intensifier is installed, which is made in the form of a rod 11, one end of which is fixed to the blank circular surface of the cylindrical insert of the swirler 6 with a screw 10, and at the other end of which a second flow swirl 12 is mounted, made in the form of a sleeve with screw external thread with a large step of a trapezoidal profile and fixed by means of an internal thread on a rod with a cone fairing 14.

Centrifugal vortex nozzle operates as follows.

In the cavity of a deaf cylindrical insert acting as a centrifugal fluid swirl 6, a vortex is formed that swirls a stream of fluid flowing out of a conic throttle hole 8. A swirling fluid flow in the insert cavity is formed by mixing jets flowing out from tangentially directed channels 13. At the exit a fluid flow is formed from the insert cavity, characterized by a constant tangential velocity. In this case, the angular velocity of the swirling fluid flow in the channel of the nozzle 5 of the atomizer determines the value of the spray angle of the generated gas-droplet flow.

The magnitude of the tangential velocity in the cavity of the insert depends on the ratio of the total cross-sectional area of the tangential channels 13 and the cross-sectional area of the axial conical throttle hole 8. The intensive formation of cavitation bubbles in the swirling fluid flow occurs in the intensifier of the twist of the fluid flow, which is made in the form of a rod 11, at the end of which mounted the second swirl flow 12, made in the form of a sleeve with a screw external thread with a large pitch trapezoidal profile. The mixing of two vortex flows at the outlet contributes to the formation of cavitation bubbles in the swirling fluid flow and thereby increases the spray pattern of the liquid.
