Axial sprinkler

Research of experimental data (Nukiyama, 1938 Radcliffe, 1953 and Miesse, 1955) about character of a deviation various to diameter and an outflow velocity of streams of water under the influence of a gas stream, moving with various speed, shows that inferred above the formula and criterion scores for a flnding of optimum location of a sprinkler 0 for liquid supply can be passed round, apparently, only for the zone of an irrigation restricted on a size. Definition of the maximum zone of the irrigation served by an axial sprinkler, at the moment a theoretical way is not obviously possible and, therefore, it should be made experimentally. Quite probably that for industrial scrubbers at which the apparatus cross-section will be more than the maximum spray of an irrigation formed by one connecting pipe, uniform water delivery on cross-section and provision of fidl shutdown of a plane by a liquid can be had only at installation of several sprinklers. Definition of optimum location of sprinklers in this case can be defined, apparently, from the expression similar Eq. (6.34), if instead of d in the formula (6.34) to substitute d ...

Increase of efficiency dust separation is caused by installation in the device of the axial sprinkler punched by apertures of small diameter, placed on a screw line. Apertures are executed in such a manner that the jet of a liquid from them is directed tangential to a surface of an axial sprinkler. The comer of an inclination of a jet is provided with directing plugs, compaction in apertures of an axial sprinkler. Thus due to impact following under a pressure the spiral film-drop liquid veil is formed of apertures of an axial sprinkler of liquid jets with a peripheral edge of blades vortex generator. 

For improvement of conditions of clearing of gas on length of the cylindrical chamber 1 (Figure 20.5) the axial sprinkler 3 pimched—is established installed by apertures of small diameter 4 in which the irrigating liquid moves.

FIGURE 20.7 The general view bubbling— the vortical device with an axial sprinkler. 

Proposed apparatus comprises eyelone, cylindrical chamber with inlet tube, tube to transfer slurry into slurry collector, axial sprinkler perforated all over its length and plugged at its outlet. Cylindrical chamber incorporates a pair of sequentially arranged swirlers. Swirler, first along gas flow. 

The bubbling—swirling apparatuswith a parabolic air swirler according to 4)ht.1 contains cylindrical camera Ic an entrance pipe 2, the axial sprinkler 3 perforated by holes of small diameter 4 and silenced with target end. In the cylindrical chamber 1, the pair of air swirlers 5 is consistently installed, and the air swirler on an entry of a gas stream is rigidly fastened to an axial sprinkler 3, and on an exit the air swirler is executed with the central hole, equal 0.2 diameters. 

The bubbling—swirling apparatus with a conic air swirler according to Figure 20.16 contains the cylindrical chamber 1 with an entrance pipe 2, the axial sprinkler 3 perforated by holes of small diameter 4 and silenced with target end. 

Usmanova, R. R. Bubbling— the Vortical Device with an Axial Sprinkler. The Patent of the Russian Federation the Invention No 2316383. February 10,2008. The Bulletin No 4. 

In a spray column with internals (Fig. 6-29a) [6.34, 6.35] droplets are formed mainly at the feed location by means of annular sprinklers. Droplets now move under the influence of gravity and buoyancy forces through the continuous phase. The column throughput depends considerably on the phase density difference and the viscosity of the phases. Considerable axial mixing is disadvantageous. This increases with increasing column diameter/column height ratio. 

Using the had dependences Eqs. (6.25) and (6.26) it is possible to tell that compared motions of streams of the irrigation water which is getting out a sprinkler in geometrically similar apparatuses with axial input of an irrigation water will be similar, if...
