Description

I1

The invention relates to sprayers with rotating spray nozzles driven by a sprayed medium, and can be used in a fire-fighting technician for spraying fuel in power plants and in other areas of the national economy.

The purpose of the invention is to increase productivity by reducing the hydraulic resistance of the rotor

The centrifugal atomizer comprises a housing 1 with an inlet pipe 2 and a porous ring rotor 3 mounted by means of bearings A on the central axis 5. The bearing 4 is fixed by a washer 6 and nuts 7. The rotor 3 is made up of a disk 8 and a ring 9 of porous material attached to disk.

The rotor is made with a variable radius of porosity, decreasing from the inner diameter of the rotor to the outer, i.e. as the diameter of the ring 9 increases, the volume occupied by the pairs decreases. The porosity of the rotor across the width of the ring 9 is made decreasing in the direction from the end of the rotor adjacent to the distribution element 10. The spray element 10 has channels a and is made in the form of a set of strips 11 connected to housing 1 and central axis 5 and arranged with bases parallel to the end of the rotor 3. Channels

The sprayer works as follows.

Through the supply pipe 2, fluid is supplied under pressure into the housing 1 and further to the channels d. In channels C, the fluid increases speed, then enters the porous ring 9 of the rotor 3, causing it to rotate. Rotor, rotating, sprays liquid radially. The size of the liquid drops depends on the cell size of the porous ring 9 at the outlet and on the revolutions of the ring. Due to the increase in pore sizes on smaller diameters, as well as the decrease in pore sizes from the nozzles of the channels O to the disk 8, a smaller part of the liquid is reflected from the porous ring, which makes it possible to obtain an increase in the speed of the rotary liquid and improve the uniformity of . In addition, the liquid is more evenly distributed across the width of the porous ring, without concentrating in the gap between the housing and the PPPW rotor, which improves the uniformity of the sprayed liquid across the width of the rotor. Variable porosity allows the rotor to achieve maximum rotational speed by introducing a jet of fluid into the ring 9 without reflecting more than full deceleration in the porous ring and shallow. By decreasing. hydraulic resistance of the porous ring of variable porosity increases productivity.
