Description

The invention relates to a device for spraying liquids and can be used for spraying liquid chemicals and other liquids.

The purpose of the invention is to improve the uniformity and monodispersity of the liquid spraying.

Figure 1 shows a multi-disk liquid spray; figure 2 - section aa in figure 1; on fig.Z - node I in figure 1.

The multi-disk fluid dispenser comprises a hollow cylindrical body 1 with annular rows of outlets 2 and a branch pipe 3 for supplying liquid to the cavity of body 1. On the casing 1 there are mounted dispensing annular disks 4, made with a wall 5 inclined to the axis of the casing 1, bypass openings 6 in it and a shell 7. The casing 1 has an axial rotation drive (not shown).

On the outer surface of the housing 1 between the spraying disks k there are made annular grooves 8 inclined to the axis of the housing 1, in the bottoms of which there are outlet ports 2 aligned with them. 5 walls of the spray disks 4, annular grooves 8 and outlet openings 2 are inclined to the axis of the housing in one direction. The sharp edges of the 9 grooves 8 are dull and adjacent to the inner

the edges of the walls of 5 spraying disks C.

The depth of each annular groove 8 is made equal to not less than the product of the diameter (d) of the outlet by the tangent of the angle of inclination (tgoi) of the groove 8 to the axis of the housing 1.

The spray liquid works as follows.

The sprayed liquid enters the cavity of the housing 1 through the nozzle 3 and is distributed along the inner surface of the rotating housing 1. Under the action of centrifugal forces, the liquid flows through the outlet openings 2 into the annular grooves 8, half-step in the form of a film on the base of the wall 5 disk 1 and sprayed the outer edge of the shell 7. Part of the liquid flows through the bypass springs0

6 on the other side of the wall 5 and sprayed with the second edge of the calyx 7.

The liquid spreading in the annular grooves ensures its smooth flow to the surface of the walls of the spraying disks, which increases the uniformity and monodispersity of the liquid spraying. Making annular grooves with a depth of not less than the product of the diameter of the outlet opening and the tangent of the angle of inclination of the groove to the axis of the housing prevents liquid from being discharged from the outlet openings into the bypass holes of the spray disks, which also increases the monodispersity of the sprayed liquid.

The use of the invention makes it possible to increase the efficiency of treatment with liquid chemicals and reduce their consumption.
