SU1205939A1 - Centrifugal atomizer - Google Patents

Description

The invention relates to liquid disintegrating devices and can be used in various sectors of the national economy for spraying liquids in apparatuses during absorption, wetting, drying and cooling of gases, as well as in agriculture for applying chemicals and irrigating fields.

The purpose of the invention is to increase the productivity and uniformity of the liquid dispersion.

The drawing shows a centrifugal nozzle.

The nozzle comprises a cylindrical body 2 connected to the supply pipe 1 with an axial channel 3 for supplying liquid, a scraper head 4 and a swirl disk 5 with blades 6 and a rod 7.

The dispersant head 4 has a liquid swirl chamber 8 and an outlet 9. The chamber 8 freely accommodates one or several shafes 10. The ratio of the diameter of the chamber 8 to the diameter of the ball 10 is in the range of 2.0-3.5. The housing 2 is connected to the pipeline 1 by an elastic insert 11 by means of clamps 12. The insert 11 may be made in the form of a pin or a metal bellows. The chamber 8 has a flange 13, limiting the movement of the balls 10, which can be made of various materials: steel, bronze, PCB, fluoroplastic, etc.

The nozzle works as follows.

The liquid enters the body 2 from the pipe 1, passes through the grooves of the swirl disk 5 formed by the blades 6, twists in the chamber 8 of the raspyatnaya head 4 and exits through the through hole 9, forming a spray torch.

When moving in the chamber 8, the liquid seizes the balls 10 and rotates them around the rod 7. The movement of the balls 10 inside the chamber 8 causes a disturbance of the swirling fluid flow and results in a filled liquid plume, which leads to an increase in the performance of the nozzle and higher irrigation uniformities. The asymmetrical arrangement of the balls 10 inside the chamber 8 displaces the center of gravity of the body – balls system relative to the axis and leads to circular axisymmetric oscillations of the body with a dropping head, which improves the conditions for the separation of fluid particles upon exiting the outlet and improves the uniformity of the spray. The increase in the amplitude of oscillations of the housing with the spray head contributes to the connection of the housing 2 with the pipe 1 elastic insert 11.

The presence of the latter between the housing 2 and the pipeline 1 also reduces the vibration of the pipeline.

The use of the invention at the stage of drying chlorine gas of sulfuric acid makes it possible to reduce electricity consumption.
