Description
40 454 284 Shuntkanalen till en utloppsvürmepanna är vanligen an- ordnad utanför pannan och är spjället gjort 1 två delar, varvid en av spjälldclarna reglerar flödet strömmande in i pannan och den andra delen flödet strömmande in i shunt- kanalen. Nackdelen vid en sådan anordning är det faktum, att båda spjälldelarna kan samtidigt stängas, varvid utlopps- kanalen är obrukbar. 40 454 284 The shunt channel for an outlet heating boiler is usually arranged outside the boiler and the damper is made in two parts, one of the damper cells regulating the flow flowing into the boiler and the other part the flow flowing into the shunt channel. The disadvantage of such a device is the fact that both damper parts can be closed at the same time, whereby the outlet channel is unusable.
En ljuddämpare är vanligen anordnad i utloppskanalen efter utloppsvärmepannan och shuntkanalen, varvid en till- räcklig ljuddämpning garanteras även när utloppsvärmepannan är i drift. Detta system lider av den nackdelen att det är dyrbart, kräver ett stort utrymme och är tungt till sin konstruktion på grund av ett flertal delar. Ändamålet med uppfinningen är att åstadkomma en ny, enklare och mera eko- nomisk utloppsvärmepanna.A muffler is usually arranged in the outlet duct after the outlet heating boiler and the shunt duct, whereby a sufficient sound attenuation is guaranteed even when the outlet heating boiler is in operation. This system suffers from the disadvantage that it is expensive, requires a large space and is heavy in its construction due to a number of parts. The object of the invention is to provide a new, simpler and more economical outlet heating boiler.
Uppfinníngen hänför sig sålunda till en utloppsvärme- panna bestående av en konvektíonsdel innehållande skruvfor- made vattenrör och utmärkes utloppsvärmepannan huvudsakligen av att konvektionsdelen är formad såsom ett ringformigt ut- rymme, att en shuntkanal för utloppsgaser är utbildad i cylindern omgiven av det ringformiga utrymmet och att väg- garna hos shuntkanalen är fodrade med ett ljudabsorberande material, så att shuntkanalen samtidigt fungerar som en ljuddämpare.The invention thus relates to an outlet heating boiler consisting of a convection part containing helical water pipes and the outlet heating boiler is mainly characterized in that the convection part is shaped as an annular space, that a shunt duct for exhaust gases is formed in the annular space. the walls of the shunt duct are lined with a sound-absorbing material, so that the shunt duct also acts as a muffler.
Jämfört med kända utloppsvärmepannor och ljuddämpare är utrymmet, som krävs vid värmepannan enligt uppfinningen, väsentligt mindre, exempelvis är höjden, som krävs för agg- regatet, omkring hälften av det utrymme som krävs för en värmepanna och ljuddämpare anordnade efter varandra. Emedan shuntkanalen och ljuddämparen befinner sig inuti värmepannan uppnås en väsentlig reduktion i vikt. En gnistsläckare an- vänds såsom en bärstruktur, vilket likaså reducerar den totala vikten. I värmepannan enligt uppfinningen används en enkel klaffventil såsom spjäll, vilken är pålitlig i funk- tion och har goda regleringsegenskaper.Compared with known outlet heating boilers and silencers, the space required for the boiler according to the invention is significantly smaller, for example the height required for the unit is about half of the space required for a boiler and silencers arranged one after the other. Since the shunt duct and muffler are located inside the boiler, a significant weight reduction is achieved. A spark extinguisher is used as a support structure, which also reduces the total weight. In the boiler according to the invention, a simple flap valve such as a damper is used, which is reliable in function and has good control properties.
I det följande beskrivs uppfinningen mera i detalj under hänvisning till en föredragen utföringsform, visad på rit- ningen.h Eigur I visar en sidovy av värmepannan.In the following, the invention is described in more detail with reference to a preferred embodiment, shown in the drawing. Figure 1 shows a side view of the boiler.
Figur 2 visar en vy uppifrån av pannan. 40 _ 454 284 Figur 5 visar en längdscktíon av pannan.Figure 2 shows a top view of the boiler. Figure 5 shows a longitudinal section of the boiler.
I figur 1 betecknar hänvlsníngsbctcckníngen 1 värmcpan- nans yttre höljc. Numren 2 och 3 betecknar ínlopps- och ut- loppsöppningar för utloppsgascr. Värmepannans fördelningsor- gan betecknas med nummer 4 och en säkerhetsventíl med nummer S. Fästöron för värmepannan betecknas med nummer 6 och en tryckmätare med nummer 7. Drívmekanísmen till ett shunt- spjäll 12 betecknas med nummer 8 och luckor, för underhåll, upptill på pannan med nummer 9. I den nedre konformade delen av pannan är ett grenrör 10 anordnat, från vilket pannans tvättvatten och läckvatten från konvektionsdelen strömmar ut.In Figure 1, the reference numeral 1 denotes the outer casing of the heating boiler. Numbers 2 and 3 denote the inlet and outlet openings for the exhaust gases. The boiler distribution means are denoted by number 4 and a safety valve by number S. The boiler fitting ears are denoted by number 6 and a pressure gauge by number 7. The drive mechanism for a shunt damper 12 is denoted by number 8 and doors, for maintenance, at the top of the boiler with number 9. In the lower cone-shaped part of the boiler a branch pipe 10 is arranged, from which the washing water of the boiler and leaking water from the convection part flow out.
Konvektionsdelen 21 upptagande skruvformade vattenrör 11 visas i figur 3. Konvektionsdelen 21 har ringform varvid en shuntkanal 13 för utloppsgas är formad i cylindern 22 om- given av delen 21. Cylindern Z2 är fodrad med ett ljudabsor- berande material 16, exempelvis glasull, ovanpå vilket ett skyddsmembran och en perforerad stâlplåt 14 är anordnade.The convection part 21 receiving helical water pipes 11 is shown in figure 3. The convection part 21 has an annular shape in which an shunt channel 13 for exhaust gas is formed in the cylinder 22 surrounded by the part 21. The cylinder Z2 is lined with a sound-absorbing material 16, for example glass wool, on top of which a protective membrane and a perforated steel plate 14 are provided.
För att förbättra ljuddämpningen är en andra cylinder 23 med ett ljudabsorberande material 16 och skyddande belägg- ning 15 anordnad inuti cylindern 22.To improve the sound attenuation, a second cylinder 23 with a sound-absorbing material 16 and protective coating 15 is arranged inside the cylinder 22.
Shuntspjället eller ventilen 12 är monterad i ett rör förbundet med den övre änden av shuntkanalens ljuddämpare 13, varvid ventilens 12 axel är kort och lagren kan placeras utanför pannan.The shunt damper or valve 12 is mounted in a tube connected to the upper end of the shunt channel muffler 13, the axis of the valve 12 being short and the bearings being placed outside the boiler.
Blad 17 i den nedre änden av ljuddämparen 13 fungerar som gnistsläckare. Bladen 17 är företrädesvis monterade så- som ett stödorgan för den innersta cylindern, antingen direkt eller, enligt figur 3, via den skyddande delen 15; den sena- re är i de mest praktiska utföringsformerna tillräckligt kraftig för monteringsändamàlet. Alternativt kan bladen 17 monteras vid den skyddande delen 14 eller vid cylindern 22.Blade 17 at the lower end of the muffler 13 acts as a spark extinguisher. The blades 17 are preferably mounted as a support member for the innermost cylinder, either directly or, according to Figure 3, via the protective part 15; the latter is in the most practical embodiments sufficiently strong for the mounting purpose. Alternatively, the blades 17 can be mounted at the protective part 14 or at the cylinder 22.
En ínloppskanal 18 för utloppsgas slutar framför gnistsläc- karen 17 och har mindre diameter än ljuddämparen 13, så att en förbindning 19 upprättas från inloppskanalen 18 till kon- vektionsdelen 21.An inlet duct 18 for exhaust gas ends in front of the spark extinguisher 17 and has a smaller diameter than the muffler 13, so that a connection 19 is established from the inlet duct 18 to the convection part 21.
Utloppsvärmepannan fungerar på följande sätt: När spjäl- let 12 öppnas passerar utloppsgaser från ínloppskanalen ge- nom gnistsläckaren 17 till den kombinerade ljuddämpar-/shunt- kanalen 13 och avges genom utloppsöppningen 3. När spjället 12 vrids mot stängt läge ökar motståndet för shuntflödet och 454 284 en de] av utloppsgascrna avböjs genom öppningen 19 till kon- vektlonsdelen, formad av rörspíralcrna 11. När spjällct 12 är i det stängda läget, passerar all utloppsgas genom kon- vektionsdelen. Storleken hos öppningen 19 mellan ljuddämpa- ren och inloppskanalen är bestämd på basis av motståndet hos utloppskanalsystemet och motorns egenskaper. Oppningen 19 är dimensionerad så liten som möjligt, så att flödet till konvektionsdelen kommer att vara litet när shunten är i öppet läge. Även i det fall när spjället 12 är helt stängt, uppnås en mycket effektiv ljuddämpning tack vare att gasflödets riktningsändringar sker i den nedre delen av värmepannan och ljuddämparen.The outlet boiler works as follows: When the damper 12 is opened, exhaust gases from the inlet duct pass through the spark extinguisher 17 to the combined muffler / shunt duct 13 and are emitted through the outlet opening 3. When the damper 12 is turned towards the closed position the resistance of the shunt flow and 45 increases 284 one of the exhaust gases is deflected through the opening 19 to the convection part, formed by the pipe spirals 11. When the damper 12 is in the closed position, all the exhaust gas passes through the convection part. The size of the opening 19 between the muffler and the inlet duct is determined on the basis of the resistance of the outlet duct system and the characteristics of the motor. The opening 19 is dimensioned as small as possible, so that the flow to the convection part will be small when the shunt is in the open position. Even in the case when the damper 12 is completely closed, a very effective sound attenuation is achieved thanks to the changes in the direction of the gas flow taking place in the lower part of the boiler and the muffler.
Den övre delen av pannan är formad så att strämnings- motståndet vid förbindningen av shuntkanalen med konvektions- delen är negativ, vilket hindrar strömningen av utloppsgaser i fel riktning.The upper part of the boiler is shaped so that the flow resistance when connecting the shunt duct to the convection part is negative, which prevents the flow of exhaust gases in the wrong direction.
Föroreningar ackumulerade vid gnistsläckaren 17 och av- lagringar lossade vid rengöring av pannan liksom varje vat- tenläckage strömmar till bottenkornen hos pannan, från vil- ken föroreningarna kan avlägsnas genom grenröret 10.Contaminants accumulated at the spark extinguisher 17 and deposits loosened upon cleaning of the boiler as well as any water leakage flow to the bottom grains of the boiler, from which the contaminants can be removed through the manifold 10.
Det skall underförstås att anordningen enligt uppfin- ningen kan variera vad avser detaljer. Exempelvis kan gnist- släckaren 17 vara av någon annan typ, den inre konen 23 kan utelämnas från ljuddämparen 13 eller kan flödet till kon- vektionsdelen hindras av ett spjäll som stänger flödet både i shunt- och konvektionsdelen. Uppfinningen kan naturligt- vis även tillämpas vid en panna med rektangulär form; ut- trycket "ringformigt utrymme" är sålunda ej begränsat till endast en cirkulär ring. i)It is to be understood that the device according to the invention may vary in terms of details. For example, the spark extinguisher 17 may be of some other type, the inner cone 23 may be omitted from the muffler 13 or the flow to the convection part may be obstructed by a damper which closes the flow in both the shunt and the convection part. The invention can of course also be applied to a pan with a rectangular shape; the term "annular space" is thus not limited to only one circular ring. in)
