En vägg 4 i avskiljningskammaren består, såsom av fig. 2 - 5 framgår, av ett flertal vertikala, parallella rör 5 och rören hopfogande plåtar 6. kopplade till reaktorns vattenlång- för sig känt sätt, och de fungerar Rören är system (ej visat) pà i och som värmeöverföringsytor, genom vilka rökgasernas värme överförs till strömmande mediet. I plåtarna är anordnade ett flertal hål- rader 71, 72 -> 7n med hål 8 på ett avstånd från varandra i gasens strömningsríktning. det i rören I avskiljníngskammarens nedre ända är en utloppsöppning 9 för avskilda fasta partiklar anordnad. 459 232 10 15 20 25 30 35 at Fig. 3 shows the detail B in Fig. 1 on a larger scale, Fig. 4 shows the detail C in Fig. 2 on a larger scale, Fig. 5 shows the detail in Fig. 6 shows a against Fig. form. 3 seen in the direction of the arrow D, 3 corresponding alternative embodiments- The flue gases escaping from the upper part of the fluidized bed reactor 1 shown in Fig. 1 are led through an inlet opening 2 into a separation chamber 3. A wall 4 in the separation chamber consists, as of Fig. 2 - 5 can be seen from a plurality of vertical, parallel pipes 5 and the pipes joining plates 6. connected to the water-known manner of the reactor, and they function The pipes are systems (not shown) in the medium. A plurality of rows of holes 71, 72 -> 7n are arranged in the plates with holes 8 at a distance from each other in the direction of flow of the gas. the outlet end 9 of separated solid particles is arranged in the lower end of the separation chamber in the tubes.
Avskiljningskammarens motstående vägg 10 är snett anordnad i förhållande till väggen 4 så, att avskiljningskammarens tvär- snitt avtar i riktning mot utl oppet 9. Utloppet 9 står medelst ett rör ll i förbindelse med virvelbäddsreaktorns nedre del. I anslutning till öppningarnas 8 framkant 12 är snett uppåt- riktade styrflikar 13 anordnade på öppníngarnas utloppssida.The opposite wall 10 of the separation chamber is arranged obliquely in relation to the wall 4 so that the cross section of the separation chamber decreases in the direction of the outlet 9. The outlet 9 is connected by means of a pipe 11 to the lower part of the fluidized bed reactor. In connection with the leading edge 12 of the openings 8, obliquely upwardly directed guide tabs 13 are arranged on the outlet side of the openings.
Utloppsöppningarna utmynnar i en gaskanal 14.The outlet openings open into a gas duct 14.
Virvelbäddsreaktorns fasta partiklar innehållande rökgaser strömmar nedåt i avskiljningskammaren längs väggen 4 mot ut- loppet 9 för de fasta partiklarna.The solid particles of the fluidized bed reactor containing flue gases flow downwards in the separation chamber along the wall 4 towards the outlet 9 for the solid particles.
Gas avlägsnas genom öpp- ningarna 8.Gas is removed through the openings 8.
Den avlägsnade gasen strömmar styrd av styr- flikarna 13 snett uppåt in i kanalen 14, där gasen bringas att strömma uppåt.The removed gas flows controlled by the control tabs 13 obliquely upwards into the channel 14, where the gas is caused to flow upwards.
På grund av den tvâra riktningsförändringen avskiljs fasta partiklar, som fortsätter sin rörelse framåt i huvudströmningsriktningen. För att åstadkomma en effektiv av- skiljning bör en hög_ strömningshastighet upprätthållas i avskiljningskammaren. Avskiljningskammaren är därför utförd så att den smalnar av mot utloppet 9 för de fasta partiklarna. De avskilda fasta partiklarna återförs till reaktorns nedre del 10 15 459 232 medelst röret 11. Efter kanalen 14 kyls gaserna på i och för sig känt sätt samt avskiljs det i gaserna efter behandlingen kvarblivna fasta stoffet.Due to the two-way change of direction, solid particles are separated, which continue their movement forward in the main flow direction. In order to achieve an efficient separation, a high flow rate should be maintained in the separation chamber. The separation chamber is therefore designed so that it tapers towards the outlet 9 for the solid particles. The separated solid particles are returned to the lower part of the reactor by means of the tube 11. After the channel 14, the gases are cooled in a manner known per se and the solid remaining in the gases is separated after the treatment.
Pig. till öppningarna 8 i plåtarna 6 är där anordnade snett uppåt- 6 visar en alternativ utföringsform. riktade rörformiga styrorgan 15 på öppningarnas utloppssida.Pig. to the openings 8 in the plates 6 are where arranged obliquely upwards 6 shows an alternative embodiment. directed tubular guide means 15 on the outlet side of the openings.
Avskiljaren enligt uppfinningen är eventuellt ej lika effektiv son\ en cyklonavskiljare, men detta_ är enbart till fördel, avskiljaren så hålls de bättre rena på grund av de fasta emedan om det finns värmeytor i gasströmmen efter partiklarnas sotningseffekt.The separator according to the invention may not be as efficient as a cyclone separator, but this is only an advantage, the separator is better kept clean due to the solids because there are heating surfaces in the gas stream after the soot effect of the particles.
Uppfinningen är ej begränsad till ovanbeskrivna utförings- former. Sålunda kan avskiljningskammaren uppvisa ett flertal väggar försedda med hål genom vilka gas avlägsnas till ett flertal kanaler. strömnings- Styrorgan, som ändrar gasens riktning, kan även anordnas på gasutloppsöppningarnas till- loppssida.The invention is not limited to the embodiments described above. Thus, the separation chamber may have a plurality of walls provided with holes through which gas is removed to a plurality of channels. flow control means, which change the direction of the gas, can also be arranged on the inlet side of the gas outlet openings.
