Abstract

Riešenie sa týká výmenníka tepla s U rúr- kami typu para-para, ktorý zabezpečuje pře ­ nos tepla medzi prehriatou a medziprehria- tou parou parného kotlá. Jeho podstata je, že U rúrky zvázku teplovýmennej plochy sú umiestnené v medzerách medzi U rúrkami protilahlej teplovýmennej plochy.The solution concerns a steam-steam type U-tube heat exchanger, which ensures heat transfer between superheated and reheated steam of a steam boiler. Its essence is that the U-tubes of the heat exchange surface bundle are placed in the gaps between the U-tubes of the opposite heat exchange surface.

Description

Vynález sa týká výmenníka tepla s U rúr-r kamí zakotvenými v protilehlých rúrkovniciách typu para-para a rieši problematiku prevádzkovej spolehlivosti, opravitelnosti a problematiku limitované] tlakovej straty na strana prehriatej páry u parných kotlov. Hlavnou úlohou výmenníka s U rúrkami typu pará-para je zabezpečovat přenos tepla medzi prehriatou a medziprehriatou parou parného kotlá.The present invention relates to a heat exchanger with U-tubes embedded in opposing para-para tubular tubes and addresses the problems of operational reliability, repairability and limited pressure loss on the overheated steam side of steam boilers. The main task of the U-tube heat exchanger is to provide heat transfer between the superheated steam and the superheated steam.

Súčasné riešenia výmenníkov tepla obzvlášť s U rúrkami typu para-para, problematiku opravitelnosti a limitovanej tlakovej straty na straně prehriatej páry neriešla.Current solutions of heat exchangers, in particular with para-para tubes, did not address the issue of repairability and limited pressure loss on the superheated steam side.

Tieto nevýhody odstraňuje výmenník tepla s U rúrkami zakotvenými v protilehlých rúrkovniciach typu para-para podl'a vynálezu, ktorého podstatou je, že U rúrky zvázku jednej teplovýmennej plochy sú umiestnené v medzerách medzi U rúrkami protilahlej teplovýmennej plochy.These disadvantages are overcome by a heat exchanger with U-tubes anchored in opposing para-para tubes according to the invention, which is based on the fact that the U-tube bundle of one heat exchange surface is located in the gaps between the U tubes of the opposite heat exchange surface.

Výhodou výmenníka tepla s U rúrkami typu para-para podía vynálezu je vysoká prevádzková spoíahlivosť zabezpečená riešením hadov teplovýmennej plochy v tvare U, Čím sa dosiahne v podstatě nulových přídavných momentov do rúrkovníc. Opravitelnosť je zabezpečená dostatočnými roztečemi medzi hadmi teplovýmennej plochy. Limitovaná tlaková strata na straně prehriatej páry je zabezpečená konštantným prierezom hadov na straně páry v celej ich dížke.An advantage of the para-para heat exchanger according to the invention is the high operational reliability provided by the solution of the U-shaped heat exchange surface snakes, which results in substantially zero additional moments for the tube sheets. Repairability is ensured by sufficient spacing between the heat exchange surface snakes. The limited pressure loss on the superheated steam side is ensured by a constant cross section of the steam side snakes throughout their length.

Prevedenia výmenníka tepla s U rúrkami typu para-para podía vynálezu sú na připojených na obr. 1 a 2.The embodiments of the para-para heat exchanger according to the invention are shown in FIG. 1 and 2.

Prevedenie výmenníka tepla s U rúrkami zakotvenými v protilahlých plochých alebo sférických rúrkovniciach typu para-para tvořeného telesom 1, vstupným hrdlom 2 medziprehrievača páry, výstupným hrdlom 3 medziprehrievača páry, vstupnou komorou 4 prehrievača páry, vstupnou komorou 5 prehrievača páry, výstupnou komorou B prehrievača páry, výstupnou komorou 7 prehrievača páry, U rúrkami 8 zvazku teplovýmennej plochy, U rúrkami 9 zvázku teplovýmennej plochy, plochou alebo sférickou rúrkovnicou 10, plochou alebo sférickou rúrkovnicou 11, prevádzacím pavúkom 12 prehrievača páry, prevádzacím pavúkom 13 prehrievača páry, zavěšením 14 a přepážkou 15.Heat exchanger design with U-tubes anchored in opposing flat or spherical para-para tubesheets consisting of body 1, inlet neck 2 of steam superheater, outlet neck 3 of steam superheater, inlet chamber 4 of superheater, inlet chamber 5 of superheater B, outlet chamber , a steam superheater outlet chamber 7, a heat exchange surface bundle 8, a heat exchange surface bundle 9, a flat or spherical tube 10, a flat or spherical tube 11, a steam superheater 12, a steam superheater 13, a suspension 14 and a partition 15 .

U rúrky 8 zvázku teplovýmennej plochy sú umiestnené v medzerách medzi U rúrkami 9 zvázku protilahlej teplovýmennej plochy. Vstupné hrdlo 2 medziprehrievača páry je pootočené voči výstupnému hrdlu 3 medziprehrievača páry.In the tube 8, a bundle of heat exchange surface is located in the gaps between the U tubes 9, a bundle of opposite heat exchange surface. The inlet neck 2 of the intermediate superheater is pivoted relative to the outlet neck 3 of the intermediate superheater.

U rúrky 8 a 9 teplovýmenných plóch prechádzajú otvormi v rúrkovniciach 10 a 11 a sú zakotvené prostredníctvom rúrkových nástavcov privarených k rúr.kovnici a k U rúrke.The tubes 8 and 9 of the heat exchange surfaces pass through openings in the tube sheets 10 and 11 and are anchored by means of tube extensions welded to the tube sheet and to the U tube.

Vynález je možné výhodné použiť pri projektovaní parných kotlov.The invention can be advantageously used in the design of steam boilers.
