SU820898A1 - Acoustic liquid sprayer - Google Patents

Description

The invention relates to the purification of gases from dust and can be used to disperse liquid concentration reagents in gases, peppers, and their purification in various sectors of the industry.

Known acoustic spray containing two coaxial tubes, one of which is provided with a tip with radial channels and a ring resonant cavity, and the other with nozzles, and the diffuser body can be equipped with an additional resonant cavity i.

The disadvantages of this spray are the low degree of dispersion of the liquid, due to the non-use of the energy of the spraying agent in the preparation of the liquid, due to the creation of additional rupture surfaces with a frequency of their equal to the frequency of the acoustic vibrations of the spraying agent, and at the same time its bubbling, as well as a high degree of circumferential unevenness torch.ch threading and

the completeness of its filling is insignificant due to the discreteness of the distribution of the liquid in the region of its dispersion.

Closest to the technical essence and the achieved result to the proposed acoustic liquid sprayer, comprising a housing with channels for supplying liquid and gas and a nozzle, a main resonator, a divider with an axial through channel, a shank and channels for the liquid exit and an additional cavity in the form of an annular groove 2.

The main disadvantages of this acoustic liquid sprayer are the low degree of dispersion of the liquid, due to the fact that the energy of the sawing agent is not spent on the preparation of the liquid, as well as the low degree of circumferential uniformity of the spray and its small filling due to the discrete distribution of the liquid and the lack the moment of rotation of the zhndkosg before its entry into the cispergion area. The purpose of the invention is to increase the degree of cispergation of the liquid, reduce the irregularity of the spray cone, and increase the fullness of its filling. This goal is achieved by the fact that in an acoustic liquid dispenser, comprising a housing with channels for supplying liquid and gas and a nozzle, the main cut (tator, a divider with an axial through channel, a shank and channels for extracting the liquid and an additional annular groover; resonator from the side of the divider, there is a bevel chamber with a divider and its shank forming a liquid preparation chamber, which communicates with the main resonator through axisymmetric channels made in it. The gas channel and axisymmetric channels are made in spirals, the directions of which coincide. Figure 1 shows the atomizer, a general view, and Figure 2 is a view A-A of figure 1. The acoustic liquid atomizer comprises a housing 1 with channels 2 and 3 for supplying liquid and gas, respectively, and a nozzle. 4, the main resonator 5, the divider 6 with the axial through channel 7, the shank 8 and the channels 9 for the liquid outlet and the additional resonator 10 in the form of an annular groove. The main resonator 5, on the side of the dissector 6, is formed with a bevel, forming a liquid preparation chamber 11 with the divider 6 and its shank 8, which communicates with the main resonator 5 through axisymmetric channels 12 made therein. Channel 13 (the working dispersion zone for supplying The gas and axisymmetric channels 12 are formed in spirals whose directions coincide. The acoustic liquid atomizer operates as follows: A liquid passing through the 2, axial through channel 7, the cavities of the shank 8 of the dissector 6, the channels 9 to exit the liquid enters the liquid preparation chamber 11 and into the dispersion work zone 13. The gas flow passing through the spiral channel 3 twists and enters the additional resonator 1 O. In the gas flow passing further through the nozzle 4 and the main resonator 5, high-energy acoustic waves that propagate in the dispersion work zone 13. Acoustic waves also propagate along axisymmetric channels 12 of the main resonator 5, which act as waveguides, and post into the liquid preparation chamber 11, where the liquid is prepared before being dispersed in the dispersion working zone 13. Thus, the presence of axially symmetric through channels — waveguides in the main resonator of an acoustic fluid dispenser, allows preparing the liquid before spraying it, using the energy of the spraying agent more efficiently and simultaneously dispersing the dispersion process. The tangential arrangement of these channels creates a moment of rotation of the fluid, which improves the spray cone and increases its filling capacity. The use of the proposed acoustic atomizer facilitates the spraying of low-pressure liquids without reducing the quality of spraying and distribution of the plume, and also prevents clogging of the annular gap, since the discontinuity surfaces in the liquid produce a damaging effect on the solid impurities in the liquid, and saves the flow of liquid at that. the same positive result of using a spray conditioner.
