Abstract

The invention relates to a spray-drying technique and can be used in the manufacture of chemical reagents and highly pure chemical substances. The goal is to improve the quality of sprayed liquid. To do this, in the spray disc, the rear wall of the wedge-shaped protrusions is formed tangentially to the side surface of the housing, and the front wall is concave and inclined to the axis. The angle of inclination of one protrusions was chosen not less than 0 and not more than 60 °, and on alternating protrusions it was chosen to supplement the angle of the previous protrusion up to 180 °. The through channels are made through a protrusion at an angle chosen not less than 45 and not more than 75 ° relative to the axis of the corresponding radial channels of the housing. The front wall of the wedge-shaped protrusions is formed by two inclined surfaces, the angle between which is not less than 30 and not more than 180 °. 1 hp f-ly, 5 ill.

The invention relates to the equipment of chemical and related industries and can be used in the manufacture of chemical reagents and highly pure chemicals.

The aim of the invention is to improve the quality of the spray liquid.

Fig, I shows a spray disc, general view; FIG. 2 is a section A-A in FIG. fig.Z - isometric spray disc; Fig. 4 shows a spray disc with wedge-shaped protrusions formed by two inclined surfaces, a general view; figure 5 - isometric spray disk in Fig, 4.

The spray disc contains an hollow body 2 mounted on the drive shaft I with a fluid supply channel 3, radial exhaust channels 4 and outlet openings 5 on the side surface of the housing 2. Before each hole 5 on the side surface of the housing 1 there are wedge-shaped protrusions 6 with through holes made in them channels 7,

The back wall 8 of the protrusions 6 is formed tangentially to the side surface of the housing 2, and the front wall 9 of the vagnucha is inclined to the axis, the Ot angle of which is on one (their outer grooves 6 are not less than 0 and not more than 60,

The front wall 9 of the wedge-shaped protrusions 6 can be formed by two inclined surfaces, the angle between which not less than 30 and not more than 180 °, 30 ° ot Јl80 ° is selected, while providing an extension of the flame angle

The spray disc works as follows.

The product to be sawn enters the E cavity of the housing 2 and spreads along the radial channels 4. When the disk 2 rotates at an angular velocity CO, centrifugal forces expel the liquid in the form of jets from the holes 5, fall onto the front wall 8 of the protrusion 6, from which sawing occurs . When air flows around the protrusions 6, as well as due to the presence of through channels 7, you

the surface of the housing 2 there are secondary vortices (swirling vortex flows), generating transverse waves and thus contributing to the fragmentation of the film or stream into drops. Through channels 7 on the projections 6 provide additional supply of air flow to the edge of the front wall 8 of the projection 6 of the housing 2, generating additional transverse

Claims (1)

1. A spraying disc containing a housing mounted on the drive shaft with a fluid supply channel and radial exhaust channels and wedge-shaped protrusions on a side surface with through channels formed therein, characterized in that, in order to improve the quality of spraying the liquid, the rear wall of the protrusions is formed by a tangent to the side surface of the body, and the front is concave and made with a slope to the axis, the angle of which on some projections is not less than 0 and not more than 60 °, and on alternating projections it is chosen to supplement the angle of the previous one sticking to 180 ° C, the through channels being made through the protrusion at an angle chosen not less than 45 and not more than 75 ° relative to the axis of the corresponding radial channels. 2, the disk according to claim 1, which differs from the fact that the front wall of the wedge-shaped protrusions is formed by two inclined surfaces, the angle between which is not less than 30 no more than 180 °. reptile W8ЈЈS1 Editor H «Gorvat Compiled by AvChagg-Boru Tehred L.
