Abstract

The invention allows to intensify the drying process and simplify the design of the nozzle. For this, the nozzle body 1 is made with a central opening 6, the Nozzles 4 channels 2 of the housing 1 are located around the opening 6 in concentric rows. Channels 2 of housing 1 in the adjacent rows have an opposite slope. The heat carrier, washing the nozzle, is divided into two streams. The first flow of the coolant is formed by the central hole 6, the second by the walls 7 of the dryer and the nozzle body 1. By reducing the flow area, the velocity of the coolant increases and turbulization of the coolant flow occurs. 2 Il. c & (L S so oo 05 00

This invention relates to a technique for drying solutions and suspensions and may find application in various industries.

The aim of the invention is to intensify the drying process and simplify the design.

FIG. 1 shows the nozzle with an hour

The slip is supplied to the heat carrier 8 in the lower part of the dryer. The heat transfer fluid over the nozzle is divided into two streams. The first coolant flow is formed by the central hole 6, the second by the walls of the dryer 7 and the nozzle body 1. By reducing the flow area

fine cut, isometric; 2 to 10, the speed of the coolant is significantly lower than the average ring of the nozzle.

The nozzle contains a cylindrical body 1 with inclined channels 2, placed on the working surface 3 of the body 1 in the form of separate nozzles 4, 15 collector 5 ,. the central hole 6. The nozzle is installed in the dryer 7 and is washed by a coolant 8. The nozzle can be made of separate threaded rings.

The nozzle works as follows.,

Fluid (slip) under pressure is fed into the manifold 5, after which it enters the inclined channels 2 formed by the right and left cutting rings. The passage through the repeatedly intersecting channels 2, the slurry is broken up into small droplets and sprayed over the section O of the dryer 7 as an annular torch. Simultaneously with the flow

the flow of heat-transfer fluid increases and occurs.
