Description

one

The invention relates to a heat engineering technique and can be used in fuel combustion installations.

The purpose of the invention is to reduce hydraulic resistance and increase reliability by increasing the strength of the nozzle

FIG. 1 shows a heat exchange unit, a general view, in a perspective view in FIG. 2 is the same, top view; FIG. 3 is a section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2; FIG. 5 shows a section B-B in FIG. 2; FIG. 6 - nozzle, longitudinal section,

The nozzle of the regenerator contains tightly packed horizontal layers 1 heat exchange units 2 with a system of vertical openings in the form of truncated cones 3 and, moreover. The smaller base of the truncated cones and 4 adjacent holes in the Bunk with 2 within the same layer 1 are directed in opposite directions. The truncated cones 3 and 4 of block 2 in adjacent layers x 1 are placed coaxially and also oppositely directed by smaller bases.

The side faces of blocks 2 are in the shape of parts of a truncated cone 3 or 4, which, when the nozzle is laid out, form full truncated cones 3 and 4. To ensure the linking of blocks 2, they are made symmetrical relative to the central axes A-A and C-Ci.

The blocks are equipped with locks in the form of protrusions 5 and 6 and grooves 7 and 8. For - laying out the horizontal layers 1 of the nozzle, the blocks 2 are laid out in such a way

so that the protrusions 5 coincide with the slots 7, and the projections 6 - with the grooves 8. With such a layout, the large bases of the cones 3 of the blocks 2 of the first layer 1 coincide with the large bases

the cones 4 of the block 2 of the subsequent layer 1 and, accordingly, the smaller bases of the cones are the 3rd smaller bases of the cones 4 of the subsequent layer 1, resulting in the formation of diffuser-confused channels 9 in the nozzle.

The nozzle of the regenerative heat exchanger works as follows

During the heating period, the combustion products move through the channels 9, usually from top to bottom, and give off heat to the accumulator blocks 2. After the heating period ends, the supply of the combustion products is turned off and the blast is fed through the same channels 9, usually from the bottom up, which takes heat from the packed blocks 2 , and is heated, t, e "a cooling period is underway.

The alternating arrangement of the menilic bases of the truncated cones 3 and 4 allows to increase the number of holes in block 2 and to reduce the hydraulic resistance, and also due to the constant contact surface between the blocks 2 for all layers, to increase the structural strength.
