Abstract

A BAFFLE A plurality of parallel tubes in the form of at least a first plurality of parallel tube rows and a second plurality of parallel tube rows are supported by a baffle comprising an outer ring capable of surrounding the tubes and a plurality of parallel rods which form a plurality of parallel chords with the outer ring wherein the rods are capable of passing in the outer ring the tubes forming adjacent parallel tube rows of one plurality of parallel tube rows and wherein the number of rods in the baffle is substantially less than the total number of rods which could be positioned in the spaces between the tube rows in the plurality of parallel tube rows.

Description

39 падак}щих с р дами предыдущей решетки j. Планки 2 могут быть помещены также между трубами 3 с чередованием свободных РЯДОВ с р дами труб, зан тых планками 2, при этом планки каждой последующей решетки 1 помещаютс в р дах труб 3, не совпадающих с р дами предыдущей решетки 1. Устройство работает следующим обра ,зом. Один из теплоносителей прокачиваетс по теплообменным трубам 3 и выводитс по технологическому назна ..чению. Другой теплоноситель подаетс в межтрубное пространство , проходит между р дами труб 3, обмени ваетс теплом с теплоносителем, прокачиваемым по трубам 3, и выводитс из теплообменника. Планки каждой поперечной решетки установлены на части р дов, потери давлени дл теплоносител в межтруб ном пространстве на каждой решетке незначительны, скорость теплоносиТел увеличиваетс и процесс теплообме на интенсифицируетс .39 padak with the rows of the previous lattice j. Straps 2 can also be placed between pipes 3 with alternating free ROWS with rows of pipes occupied by strips 2, while the strips of each subsequent grid 1 are placed in rows of pipes 3 that do not coincide with the rows of the previous grid 1. The device operates as follows zom One of the coolants is pumped through the heat exchange tubes 3 and is withdrawn in accordance with the process designation. The other coolant is supplied to the annular space, passes between the rows of tubes 3, exchanges heat with the coolant pumped through the tubes 3, and is discharged from the heat exchanger. The slats of each transverse grid are installed on parts of the rows, the pressure loss for the coolant in the annular space on each grid is insignificant, the speed of the coolant increases and the heat exchange process is intensified.

Claims

/ W Claim 1. Spacing device for a tube bundle of a heat exchanger containing at least three transverse grids along the length of the beam in the form of a set of strips placed between tubes arranged in rows, characterized in that, in order to intensify the tel exchange and reduce losses pressures, in each lattice, the slats are placed only on parts of the beam rows, and adjacent lattices are displaced one relative to another along the beam section.

2. The device according to claim 1, wherein the slats of each grid are placed between adjacent rows of pipes. Sources of information taken into account when experts 1. USSR author's certificate №, cl. F28 D 7/00, 1972.
