SU1468579A1 - Nozzle for atomizing suspensions, solutions or pulp ,particularly, of mineral fertilizers in drum granulator/dryer - Google Patents

Abstract

The invention relates to the chemical industry, it can be used for spraying, 1vapi suspensions, solutions and nyvibn mineral fertilizers. The purpose of the invention is to increase reliability. Two autonomous fluids and spraying agents are used with one common center .1 noTOKO.Ni in the nozzle, which makes it possible, without stopping the flow of the liquid into the nozzle, alternately cleans the liquid channel (blow through with steam). This reduces downtime associated with cleaning the nozzle and increases its reliability. I h. n. f-, 1y, 3 ill. S

Description

one

The invention relates to chemical purity, namely, to the production of granulated 1; mineral fertilizers in drum granule tori-dryers, and is intended to dissolve solutions, suspensions or pulps of mineral fertilizers.

The purpose of the invention is to increase the reliability of work.

 FIG. 1 shows a drum pellet - torus-super1ka, longitudinal section; in fig. 2 - nozzle, longitudinal section; in fig. 3 is a view A of FIG. 2

In the drum granulator, sui, 1ke, a nozzle 2 is installed along the axis of the drum 1, containing concentrically located central 3 and outer 4 pipes for supplying spray air and internal pipe 5 for supplying scattered material. In the outer 4 and inner 5 pipes are installed. 1n diametrically located partitions 6 and 7, while the partitions 6 and 7 are located in a horizontal plane. The outer and inner pipes are equipped with two nozzles 8. 9 and 10, 11 for the supply of a nosal air and a sprayed material. Ex rpii of central pipe 3 is installed, 1 en ogpeppe 12 with deflector 13.

The nozzle works as follows.

with

rings, crushed by a common central air flow. The air coming from the upper half-ring breaks up a jet of liquid emanating from the upper half-ring, and the air coming from the lower half-ring breaks up a stream of liquid emanating from the lower half-ring.

The resulting liquid spray is directed to a curtain of material falling from the blades into the drum 1.

If the output nozzle of one of the half-rings is clogged for supplying fluid, this ring is turned off and the second half-ring is working, which increases the reliability of the nozzle, reduces downtime and increases productivity.
