Abstract

The invention relates to a spray technique and can be used in drying plants, mass transfer devices, sprayers with a finely dispersed spray. The goal is to increase the reliability of the sprayer. For this purpose, the liquid sprayer is provided with protective elements placed in the reflective plates made on the working surfaces and decreasing to the periphery of the slots. Making the slots and installing protective elements in them will speed up the replacement of elements, shorten the recovery cycle and increase the duration of use of the sprayer. This also improves the maintenance conditions of the sprayer. 4 il.

Description

The invention relates to a spray technique, can be used in drying plants, mass transfer devices, sprayers with a fine spray in the chemical and other industries and is an improvement of the known sprayer according to the authors. St. No. 1123731.

The aim of the invention is to improve the reliability of the sprayer.

FIG. 1 shows a sprayer, vertical section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the same, the embodiment of the working surfaces of the reflective surfaces; in fig. 4 is a view B in FIG. 2

The liquid sprayer contains a vertically mounted drive shaft 1, a spray head 2 fixed thereto with a lid 3, pressure channels 4, nozzles 5 and baffle plates 6, and a supply pipe 7.

In addition, the sprayer is equipped with a disk 8 mounted on the spraying head. 2 and can be rotated relative to the axis of the dispenser disk 8, and () T |) pressing plates 6 are attached to the front. The sprayer is also equipped with: uiiiunin:) iM element 9, placed on working film-forming surfaces of the reflection plates fi and pressed to their periphery by the slots Id.

the grooves 10 with interchangeable protective elements 9 installed in them are reduced to the periphery of the plates 6. When the shaft 1 with the head 2 rotates, the protective elements 9 under the action of centrifugal force are clamped in the grooves 10, while ensuring reliable fastening of the protective elements 9.

The feed pipe 7 supplies fluid to the head 2, which then flows to the channels 4 and nozzles 5 and under the action of centrifugal force flows out in the form of jets to the protective elements 9 installed in the grooves 10. When the elements 9 fall, the liquid streams are converted into thin films which, when leaving the elements 9, disintegrate into small droplets, forming a fine spray of sprayed liquid.

When elements 9 fail due to hydroabrasive destruction and the associated changes in the spray characteristics and dispersion of protective elements 9, which are necessary in this case, as well as using elements 9 that have different mechanical properties, another film-forming surface (roughness) , it takes a short time to replace some elements 9 with others by performing the simplest operations: removing element 9 from groove 10 - installing element 9 into groove 10, using the same branches living plates 6.
