SU1581989A1 - Device for measuring dimensions between holes - Google Patents

Abstract

This invention relates to a measurement technique. The purpose of the invention is the expansion of technological capabilities. The device contains a base 1 with two symmetrical scales 2 having a common point of reference, frames 4 and 5 installed in the grooves 3 on the axes of conical calibers with the possibility of moving along the scales and removable rulers 10 and 11. When measuring cone calibers by moving frames 6, 7 and removable rulers 10 and 11, on which grooves 13 and 14 are formed, are installed in the holes and the distances between the holes are determined on scales 2, 14 and 15. 3 il.

Description

The invention relates to a power system, and in particular, to devices of contact devices for cooling water in the water recycling systems of industrial enterprises. .

The purpose of the invention is to increase the efficiency of heat and mass transfer by additional turbulization of the flows of heat-exchanging media, as well as the intensification of heat and mass transfer.

Ya FIG. _x 1 shows the sprinkler plate; Η3 · φίΐΓ.2 - cooling tower sprinkler, general view. ί The sprinkler plate contains protrusions made on one side of the sheet 1, 2 in the form of hollow truncated cones with holes 3 and 4 at the vertex οοηοβ3ηηη μ μ respectively and in the side walls with holes 5. ho the protrusions 6 are hollow in the checkerboard ί cut cones with holes 7 and 8 at the warp and apex and with a solid side wall. The protrusions 2 are made with a diameter of base 3 and a height that deliver 1.2-2.5 diameters of the base 7 and the height of the protrusions 6. The sprinkler of the tower is composed in the form of rows of said plates, while the plates are interconnected by smaller bases of protrusions 2 and 6 with the formation of channels 9 and W.

Water to be cooled is sprayed over the sprinkler. Flowing through a developed system of channels 9 and 10 and through Holes 3, 4, 7, 8, and 5, the water flow breaks into drops many times. In this case, its mixing and redistribution occurs. The air coming from below also passes through the mentioned channels and openings and interacts with water drops.

The proposed layout of the irrigator of the plates is effective for contaminated circulating water.

Claims (2)

Claim 10 1. A sprinkler plate containing staggered protrusions made in a sheet on both sides in a checkerboard pattern with hollow truncated cones with holes in the base and apex, while additional holes are made in the side walls of 15 protrusions located on one side of the sheet, characterized in that that, in order to increase the efficiency of heat and mass transfer by additional turbulization of 20 flows of heat-exchanging media, the protrusions placed on the opposite side of the sheet are made with a continuous side wall, while the protrusions from the hole pits in the walls are made with a diameter of 25 bases and a height of 1.22.5 times the diameter of the base and the height of said protrusions. 2. The sprinkler of the cooling tower, containing rows of plates with conical protrusions, characterized in that, in order to intensify heat and mass transfer, the protrusions are made in the form of truncated cones and the plates are interconnected by smaller bases of the cones of the protrusions.
