Laite kiinteiden komponenttien poistamiseksi savukaasuista -Anordning för avlägsnande av fasta komponenter ur rökgaserDevice for removing solid components from flue gases -Anordning för avlägsnande av fasta Component ur rökgaser
Esillä oleva keksintö kohdistuu laitteeseen kiinteiden komponenttien poistamiseksi savukaasuista, joka soveltuu erityisesti leijukerrosreaktorista tulevien savukaasujen käsittelyyn, jossa savukaasuista erotetut kiinteät hiukkaset palautetaan leijukerrosreaktoriin.The present invention relates to an apparatus for removing solid components from flue gases, which is particularly suitable for the treatment of flue gases from a fluidized bed reactor, in which solid particles separated from the flue gases are returned to the fluidized bed reactor.
Tällaisissa leijukerrosreaktoreissa on kiintoaineksen erottaminen aikaisemmin suoritettu syklonierottimissa. Syklo-nierottimen epäkohtana on se, että se vaatii paljon tilaa. Sillä on myös suuri massa ja sen johdosta suuri lämpökapasiteetti, jonka vuoksi reaktorin ylös- ja alasajo on aikaavievää. Syklonierottimen muoto aiheuttaa vaikeasti hallittavissa olevia lämpöjännityksiä. Myös laitteen kuluminen aiheuttaa ongelmia.In such fluidized bed reactors, solids separation has previously been performed in cyclone separators. The disadvantage of a cyclo separator is that it requires a lot of space. It also has a large mass and, as a result, a large heat capacity, which makes the running up and down of the reactor time-consuming. The shape of the cyclone separator causes heat stresses that are difficult to control. Wear of the device also causes problems.
US-patentista 4,253,425 on tunnettu leijukerrosreaktori, jossa savukaasut saatetaan virtaamaan suuntaa muuttavilla väliseinillä varustetun kanavan läpi, jolloin kiinteät partikkelit erottuvat savukaasujen törmätessä levyihin ja putoavat alas kanavan alaosaan, josta ne palautetaan reaktoriin. Ehdotetun laitteiston avulla ei kuitenkaan voida tehokkaasti poistaa kiintoainesta kaasuista.U.S. Pat. No. 4,253,425 discloses a fluidized bed reactor in which flue gases are caused to flow through a channel with diverting partitions, whereby solid particles separate as the flue gases collide with the plates and fall down to the bottom of the channel, from where they are returned to the reactor. However, the proposed equipment cannot effectively remove solids from the gases.
Esillä olevan keksinnön tarkoituksena on aikaansaada rakenteeltaan yksinkertainen laite kiintoaineksen erottamiseksi tehokkaasti kaasuvirrasta.It is an object of the present invention to provide a device of simple construction for efficiently separating solids from a gas stream.
Keksinnön tarkoituksena on myös aikaansaada laite, jolla lämpöä voidaan ottaa talteen kuumasta kaasuvirrasta.It is also an object of the invention to provide a device with which heat can be recovered from a hot gas stream.
Keksinnön mukaiselle laitteelle, joka käsittää tulo- ja poistoaukoilla varustetun erotuskammion, joka käsittää seinämän, jossa kaasun virtaussunnassa on useita, välimatkan 2 66297 päässä toisistaan olevia kaasunpoistoaukkoja, joiden yhteyteen on järjestetty ohjauselimet kaasun poistamiseksi kaasun päävirtaussuunnasta oleellisesti poikkeavassa suunnassa on pääasiallisesti tunnusomaista se, että kaasunpoistoaukot on sijoitettu jäähdytysputkien välisiin levyihin.The device according to the invention, comprising a separation chamber with inlet and outlet openings, comprising a wall with a plurality of spaced outlet openings 2 66297 in the gas flow direction, in connection with which control means for discharging gas in a direction substantially different from the main gas flow direction is substantially characterized by is placed on the plates between the cooling pipes.
Keksintöä selostetaan seuraavassa lähemmin viitaten oheisiin piirustuksiin, joissa kuvio 1 esittää kaaviomaista pystyleikkausta leijukerros-reaktorista, johon kuuluu keksinnön mukainen erotin, kuvio 2 esittää kuvion 1 leikkausta viivaa A-A pitkin, kuvio 3 esittää kuvion 1 kohtaa B suuremmassa mittakaavassa, kuvio 4 esittää kuvion 2 kohtaa C suuremmassa mittakaavassa, kuvio 5 esittää kuviossa 3 esitettyä kohtaa katsottuna nuolen D suunnassa, ja kuvio 6 esittää kuviota 3 vastaavaa vaihtoehtoista suoritusmuotoa .The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 1 shows a schematic vertical section of a fluidized bed reactor comprising a separator according to the invention, Figure 2 shows a section of Figure 1 along line AA, Figure 3 shows Figure 1 on a larger scale, Figure 4 shows C on a larger scale, Figure 5 shows the site shown in Figure 3 as viewed in the direction of arrow D, and Figure 6 shows corresponding to Figure 3 an alternative embodiment.
Kuviossa 1 esitetyn leijukerrosreaktorin 1 yläpäästä poistuvat savukaasut johdetaan tuloaukon 2 kautta erotuskammioon 3. Erotuskammion yksi seinämä 4 muodostuu, kuten kuvioista 2-5 ilmenee, pystysuorista putkista 5 ja niiden välissä olevista levyistä 6. Putket on yhdistetty reaktorin vesi/höyry-järjestelmään sinänsä tunnetulla tavalla, ja ne toimivat lämmönsiirtopintoina, joiden välityksellä savukaasut luovuttavat lämpöä putkissa virtaavalle väliaineelle. Levyissä on välimatkan päässä toisistaan useita aukkorivejä 7^, 17^, joissa on aukot 8. Erotuskammion alapäässä on kiintoaineksen poistoaukko 9. Erotuskammion vastakkainen seinämä 10 on sovitettu seinämään 4 nähden vinosti niin, että erotustilan poikkileikkaus pienenee poistoaukkoa 9 kohti. Poistoaukko 9 on putken 11 välityksellä yhdistetty leijukerrosreaktorin alaosaan. Aukkojen 8 etureunojen 12 yhteyteen on järjestetty vinosti ylöspäin suunnatut ohjaussiivekkeet 13 aukkojen poistopuolelle. Poistoaukot avautuvat poistokanavaan 14.The flue gases leaving the upper end of the fluidized bed reactor 1 shown in Fig. 1 are led through the inlet 2 to the separation chamber 3. One wall 4 of the separation chamber is formed, as shown in Figures 2-5, by vertical pipes 5 and plates 6 between them connected to the reactor water / steam system. , and act as heat transfer surfaces through which the flue gases transfer heat to the medium flowing in the pipes. The plates are spaced apart by a plurality of rows of openings 7, 17, with openings 8. The lower end of the separation chamber has a solids outlet 9. The opposite wall 10 of the separation chamber is arranged obliquely to the wall 4 so that the cross section of the separation space decreases towards the outlet 9. The outlet 9 is connected to the lower part of the fluidized bed reactor via a pipe 11. In connection with the front edges 12 of the openings 8, obliquely upwardly directed guide vanes 13 are arranged on the outlet side of the openings. The outlets open into the outlet channel 14.
loijukerrosreaktorin kiinteitä hiukkasia sisältävät savukaasut virtaavat erotuskammiossa alaspäin seinämää 4 pitkin kohti 66297 3 kiintoaineksen poistoaukkoa 9. Aukkojen 8 kohdalla kaasua poistetaan. Poistuva kaasu virtaa ohjaussiivekkeiden 13 ohjaamana vinosti ylöspäin poistokanavaan 14, jossa kaasu virtaa ylöspäin. Kaasun äkillisen suunnanmuutoksen johdosta kiinteät hiukkaset, jotka jatkavat liikettään eteenpäin päävirtaussuunnassa, erottuvat. Tehokkaan erotuksen aikaansaamiseksi on erotuskanuniossa ylläpidettävä suurta nopeutta. Tämän vuoksi erotuskammio on tehty kiinteiden komponenttien poistokohtia 9 kohti kapenevaksi. Erottunut kiintoaines palautetaan reaktorin alaosaan putken 11 kautta. Poistokanavan jälkeen kaasut jäähdytetään sinänsä tunnetulla tavalla sekä poistetaan erotuskammiossa suoritetun esierotuksen jälkeen kaasuissa oleva kiintoaines.the flue gases containing solid particles from the fluidized bed reactor flow downwards in the separation chamber along the wall 4 towards the solids outlet 9. At the openings 8 the gas is removed. The exhaust gas flows under the control vanes 13 obliquely upwards to the exhaust duct 14, where the gas flows upwards. Due to the sudden change of direction of the gas, the solid particles, which continue to move forward in the main flow direction, separate. In order to achieve effective separation, a high speed must be maintained in the separation cannon. Therefore, the separation chamber is made tapered towards the solid component outlets 9. The separated solids are returned to the bottom of the reactor via a pipe 11. After the exhaust duct, the gases are cooled in a manner known per se and, after pre-separation in the separation chamber, the solids in the gases are removed.
Kuvio 6 esittää erästä vaihtoehtoista suoritusmuotoa. Siinä levyssä 6 olevien aukkojen 8 yhteyteen on järjestetty vinosti ylöspäin suunnatut, putkimaiset, ohjauselimet 15 aukkojen poistopuolelle.Figure 6 shows an alternative embodiment. In connection with the openings 8 in the plate 6, diagonally upwardly directed, tubular guide members 15 are arranged on the outlet side of the openings.
Keksinnön mukainen erotin ei mahdollisesti ole yhtä tehokas kuin syklonierotin, mutta tämä on vain hyödyksi, sillä jos erottimen jälkeen kaasuvirrassa on lämpöpintoja, ne pysyvät kiinteiden hiukkasten nuohousvaikutuksen ansiosta paremmin puhtaina.The separator according to the invention may not be as efficient as the cyclone separator, but this is only useful because if there are thermal surfaces in the gas stream after the separator, they remain better clean due to the soot action of the solid particles.
Keksintö ei ole rajoitettu esimerkkinä esitettyyn suoritusmuotoon, vaan sitä voidaan muunnella patenttivaatimusten määrittelemän keksinnöllisen ajatuksen puitteissa. Niinpä erotuskammiossa voi olla useita seinämiä, joiden kautta kaasua poistetaan useaan poistokanavaan. Kaasun virtaus-suuntaa muuttavia ohjauselimiä voidaan sovittaa myös kaasun-pois toaukkojen tulopuolel]e.The invention is not limited to the exemplary embodiment, but may be modified within the scope of the inventive idea defined by the claims. Thus, the separation chamber may have a plurality of walls through which gas is discharged into a plurality of outlet passages. The gas flow direction changing control means can also be arranged on the inlet side of the gas outlet openings.
