Description

The invention relates to spray devices and can be used for spraying process solutions in special process equipment.

The aim of the invention is to increase the opening angle of the plume while maintaining uniform dispersion of particles throughout its volume.

Figure 1 shows the nozzle, a longitudinal section; figure 2 - section aa in figure 1; on fig.Z - nozzle, bottom view; figure 4 - section bb in fig.Z.

The fluid sprayer comprises a housing 1 with an inlet channel 2 having a cone-shaped outlet section 3, and tangential channels 4 and a nozzle tip 5 with evenly spaced holes 6 and an annular channel 7 communicated with subsequent and tangential channels 4 of case 1. In addition, at the end of the nozzle tip 5 there is an annular groove 8 of rectangular section located at the outlet of the holes b, communicating with the holes b of the tip 5, and radial grooves 9 of segment shape, with the holes b ending Single 5 are conical with a cylindrical portion 10 at the end of the nozzle body 1 and the tip 5 are connected by means of nut 11.

The spray works as follows.

The liquid sprayed through the channel 2 of the housing 1 through the channels 4 enters the channel 7, begins to move in a circle and as the pressure in the channel 7 increases through the holes b goes into the annular groove 8. At the same time, due to the shape of the holes b, the flow rate increases, which contributes more full filling of the groove 8 and stable without breaking the expiration of it spray. In addition, due to the high speed of the fluid outflow from the holes b located along the axis of symmetry of the segment grooves 9, these grooves are also filled, from where the liquid expires, forming a torch of complex shape, but a much larger area, and a large number of torch formation sources and the mutual intersection of the torches formed by the channel 7, the annular groove 8 and the radial grooves 9 ensure the relative uniformity of the dispersion of the particles.
