Menetelma ja sovitelma pyOrivan jatteenpolttorummun poistopaan jaahdyttamiseksi ja tiivistamiseksiMethod and arrangement for cooling and sealing the outlet of a rotary incinerator

KeksinnOn kohteena on menetelma pyOrivan jatteen-5 polttoruiranun poistopaan jaahdyttamiseksi ja tiivistamisek-si, jossa menetelmassa poistopaata jaahdytetaan sen lahei-syyteen syOtettavan j aahdytysvaiiaineen avulla. KeksinnOn kohteena on lisaksi sovitelma pyOrivan j atteenpolttorummun poistopaan jaahdyttamiseksi ja tiivistamiseksi, joka kasit-10 taa valineet jaahdytysvaiiaineen syOttamiseksi poistopaan jaahdyttamista vårten.The invention relates to a method for cooling and compacting the outlet of a rotating waste-5 combustion web, in which method the outlet is cooled by means of a cooling medium fed to its proximity. The invention further relates to an arrangement for cooling and sealing the outlet of a rotating waste incineration drum, which comprises means for supplying a cooling medium to the outlet for cooling.

Ongelmajdtteiden polttouuneina kaytetaan usein rum-putyyppisia pyOrivia polttouuneja. Kaikki ongelmajatteiden polttouunit ovat ns. alipainepolttouuneja, jolloin uuni py-15 ritaan pitamaan normaalissa kayttOtilanteessa n. 10-40 mmVp:n alipaineessa. TailOin mahdolliset vuodot voivat muo-dostaa merkittavan osan uuniin joutuvasta ilmasta. Ongelma-jatteenpoltto tapahtuu aina, jopa jatkossakin enemman tai våhemman panossyOttOna. Em. panossyOtOsta ja jatteen vaih-20 televasta polttoherkkyydesta johtuen kay jatteenpolttouuni usein ns. ylipaineessa aivan normaalissa kayttOtilanteessa.Rum-type rotary kilns are often used as incinerators for problem wastes. All hazardous waste incinerators are so-called vacuum incinerators, the furnace being rotated to maintain a vacuum of about 10-40 mmVp in normal use. Possible leaks from the tail can form a significant part of the air entering the furnace. Problem waste incineration always takes place, even in the future, with more or less input. Em. Due to the input consumption and the variable combustion sensitivity of the waste, the Kay waste incinerator is often a so-called overpressure under normal conditions of use.

Ongelmaksi em. uunien yhteydessa on muodostunut poistopaan rakenne. Ongelmat johtuvat mm. siita, etta poistopaan tiivistys on ns. suunnittelurajalla, joten kukaan ei . , 25 oikein ole ottanut sita omakseen. Lahes kaikki eurooppalai- set uunit ovat yhden valmistajan tuotteita ja laitevalmis-taja ei ole pitanyt tarpeellisena kehittaa ratkaisujaan tassa suhteessa. Polttouunien tiiveydesta ja rakenteesta puuttuvat lisaksi selkeat normit. Ongelmaj atteiden havitta-30 minen polttamalla on viela nykyaankin nuorta tekniikkaa, joten erilaiset osa-alueet ovat teknisesti viela suhteelli-sen alhaisella tasolla.The problem with the above furnaces is the structure of the outlet. The problems are due to e.g. that the outlet seal is so-called at the design boundary, so no one. , 25 correctly have not adopted it. Almost all European ovens are products of one manufacturer and the equipment manufacturer has not considered it necessary to develop its solutions in this respect. In addition, there are no clear standards for the tightness and structure of incinerators. The problem of incineration by incineration is still a new technology today, so the various aspects are still technically relatively low.

Aiemmin kaytetyissa pyOrivissa polttouuneissa kaytetaan poistopaan j aahdytyksessa ilmaj aahdytysta. Tilanne on 35 kaytannOssa nykyisten polttouunien yhteydessa se, etta mi- 2 92435 kali poistopaa halutaan saada jaahtymaan, tulee sen vuotaa n. 2 000 - 10 000 Nm3/h ilmaa uuniin pain. Vuoto aikaan-saadaan uunin normaalilla alipaineella seka runsaasti rei-kia sisaitavana uunin poistopaana, ts. nykyiseliaan pois-5 topaa ei jaahdy, ellei se vuoda. Nykyaan kaytetyissa rat-kaisuissa ilmaa johdetaan sopivan puhallinjarjestelyn avul-la rummun poistopaan ulkopinnalle. KaytannOssa ilma johdetaan rummun ulkopinnan ja sen ymparille sovitetun vaipan vaiiin muodostuvaan tilaan. Em. tila on jaikipolttokammion 10 puolelta suljettu osittain tulenkestavasta valusta muodos-tetuilla valukappaleilla. Valukappaleet on sijoitettu niin, etta niiden vaiiin jaa sopivia rakoja, joiden kautta ilma paasee virtaamaan jaikipolttokammioon. Em. tavalla aikaan-saadaan siis em. vuoto, joka on ensiarvoisen tarkeata jaah-15 dytykselle. Rummun poistopaan ja jaikipolttokammion seina-mdn vaiinen rakenne ei aiemmin tunnetuissa ratkaisuissa ole myOskaan tiivis, silia ko. rakenteen kautta paasee jaiki-polttokammioon huomattava maara ilmaa, esimerkkina naista ilmamaarista voidaan mainita alue 50 - 200 Nm3/h.In previously used rotary kilns, air cooling is used to cool the exhaust stream. The situation in 35 applications in connection with existing incinerators is that if 2 92435 Potassium discharge is to be cooled, it must leak approx. 2,000 - 10,000 Nm3 / h of air into the furnace. The leakage is effected by the normal vacuum of the furnace and by the abutment of the furnace, which contains a large number of holes, i.e. the current out-5 top does not cool unless it leaks. In the solutions used today, air is led to the outer surface of the drum outlet by means of a suitable fan arrangement. In use, air is led into the space formed by the outer surface of the drum and the mantle arranged around it. Em. the space is partially closed on the side of the yak combustion chamber 10 by castings formed of refractory casting. The castings are positioned so that suitable slots are distributed in their stacks, through which air can flow into the ande combustion chamber. Em. In this way, the above-mentioned leakage is obtained, which is of paramount importance for Jaah-15. The silent structure of the drum outlet and the wall-mdn of the jacketed combustion chamber is also not tight in previously known solutions, Silia in question. through the structure a considerable amount of air passes into the jaiki combustion chamber, an example of a female air volume being the range 50 - 200 Nm3 / h.

20 Aiemmin tunnettujen ratkaisujen epakohtana on mm.20 The disadvantage of previously known solutions is e.g.

se, etta ne aiheuttavat hallitsemattomia paastOja prosessi-tiloihin seka ymparistiiiJn. Ongelmana on edelleen se, etta prosessiin paasee hallitsemattomasti ilmaa, jota ei voida mitata eika saataa. Jatteen poltto perustuu jatteen havit-25 tamiseen polttamalla mahdollisimman taydellisesti. Pal ami-sessa tarvitaan ilmaa ja happea. Jotta polttaminen olisi taydellista ja hallittua tulee myOs ilmansyfitiJn olla hal-littua ja mitattavissa. Nykyiset poistopaan rakenteet ovat lisaksi monimutkaisia ja helposti vioittuvia ja lisdksi 30 kylmaa ilmaa vuotava poistopaa aiheuttaa hallitsematonta kuonanmuodostusta rummun poistopaahan. Runsaasti vuotava rummun poistopaa on edelleen aiheuttanut sen, ettei pyOri-van uunin ja kiintean jaikipolttokammion vdliseen tiivis-tykseen ole ollut aihetta, koska uunin ja jaikipolttokam-35 mion vaiista tapahtuva vuoto on joka tapauksessa suuruus-the fact that they cause uncontrolled fasting in the process spaces as well as in the environment. The problem remains that air that cannot be measured or escaped enters the process uncontrollably. Incineration of waste is based on the incineration of waste by incineration as completely as possible. Pal amine requires air and oxygen. In order for combustion to be complete and controlled, the air must also be controlled and measurable. In addition, the current discharge structures are complex and easily damaged, and in addition, 30 cold air leaking discharge causes uncontrolled slag formation in the drum discharge. The high leakage of the drum outlet has further led to the fact that there has been no need for temporary sealing of the rotary kiln and the solid combustion chamber, since the leakage from the silence of the furnace and the combustion chamber is in any case

According to the invention, the method is characterized in that a liquid-tight space is formed around the outer surface of the discharge collar in the direction of the discharge collar, by means of which the silent gap of the discharge collar and the combustion chamber is sealed, that liquid is sprayed onto by means of the walls of the liquid-tight space together and guided to the desired location for removal. The arrangement, in turn, is characterized in that the arrangement handles a guide cylinder adapted to form a liquid-tight space around the outlet in the discharge direction and piping and nozzle means for spraying liquid on the outer surface of the outlet at the boundary of the guide cylinder. -20 is for sealing the silent gap, the walls of the guide cylinder being adapted to guide the outlet to the desired location of the liquid flowing out of the outer surface.

The combustion reaction becomes as complete as possible because harmful and uncontrolled air intake into the process is eliminated. The invention provides a simple and durable outlet structure. The invention also eliminates the problem of slag formation in the drum outlet and, in addition, ai. a compact structure of a rotating drum and a fixed and combustion chamber is obtained.

Keksintoa ryhdytaan selvittamaan seuraavassa ohei-sessa piirustuksessa esitettyjen edullisten sovellutusesi-35 merkkien avulla, jolloin kuvio 1 esittaa periaatteellisena kuvantona osaa tyypillisesta jatteenpolttolaitoksesta, kuvio 2 esittaa periaatteellisena sivukuvantona 4 92435 keksinnOn mukaisen sovitelman ensimmaista sovellutusmuotoa ja kuvio 3 esittaa periaatteellisena sivukuvantona keksinnOn mukaisen sovitelman toista sovellutusmuotoa.The invention will now be described with reference to the preferred embodiments shown in the accompanying drawing, in which Figure 1 shows in principle a part of a typical waste incineration plant, Figure 2 shows in principle a side view of the first embodiment

Viitenumerolla 1 on esitetty pyOrivå jatteenpolttorumpu ja viitenumerolla 2 vastaavasti klintea jalkipolttokammio. Kuvio 1 esittaa aiemmin tunnettua laitosta, joten kuvioon 1 on viitenumeron 10 3 avulla merkitty vaiineet jaahdytysilman syOttamiseksi pyOrivan jatteenpolttorummun 1 poistopaaile. Kuvioon 1 on lisaksi ympyran A avulla merkitty jatteenpolttorummun 1 poistopaan alue, johon keksintO liittyy. Kuviossa 1 esite-tyn jatteenpolttolaitoksen muu tekniikka ja rakenne on alan 15 ammattimiehelle taysin tavanomaista ja tunnettua tekniik-kaa, joten ko. seikkoja ei tassa yhteydessa selviteta tar-kemmin.Figure 1 shows in principle a part of a typical waste incineration plant. Reference numeral 1 denotes a rotary waste incineration drum and reference numeral 2 denotes a klint foot incineration chamber, respectively. Fig. 1 shows a previously known plant, so in Fig. 1 the silencers for supplying cooling air are indicated by reference numeral 10 3 at the outlet of the rotary waste incineration drum 1. In addition, the area of the outlet of the waste incineration drum 1 to which the invention relates is indicated in Fig. 1 by means of a circle A. The other technique and structure of the waste incineration plant shown in Fig. 1 is completely conventional and known to a person skilled in the art, so that the the issues are not clarified in this context.

Kuviossa 2 on esitetty eras keksinnOn mukainen so-vellutusmuoto. Kuviossa 2 on kaytetty vastaavista osista 20 samoja viitenumeroita kuin kuviossa 1, ts. jatteenpolttorumpu on merkitty viitenumerolla 1 ja jalkipolttokammio viitenumerolla 2. KeksinnOn mukaisesti jatteenpolttorummun 1 poistopaan ulkopinnalle ruiskutetaan jaahdytysvaiiaineena toimivaa nestetta ja pinnalta pols valuva neste kootaan yh-25 teen ja ohjataan haluttuun paikkaan poistoa vårten. Em. ajatus on toteutettu kuvion 2 sovellutuksessa niin, etta poistopaan ymparille muodostetaan ohjauslieriOn 5 avulla poistopaan suuntaan nestetiivis tila ja poistopaata jaah-dyttéva neste ruiskutetaan putkisto- ja suutinvaiineiden 4 30 avulla poistopaan ulkopinnalle ohjauslieriOn rajaaman alu-een kohdalla. Poistopaan ulkopinnalta pois valuva neste johdetaan lisaksi ohjauslieriOn 5 seinamien avulla haluttuun paikkaan poistamista vårten. Termilia "poistopaan suuntaan" tarkoitetaan sita, etta ohjauslieriOn 5 rajaama 35 tila on poistopaan avautumissuuntaan tiivis niin, ettaFigure 2 shows an embodiment according to the invention. In Fig. 2 the same reference numerals as in Fig. 1 are used for the respective parts 20, i.e. the waste incineration drum is denoted by reference number 1 and the foot incineration chamber by reference number 2. closets. Em. the idea is implemented in the embodiment of Fig. 2 in that a liquid-tight state is formed around the outlet in the direction of the outlet by means of a guide cylinder 5 and a liquid cooling the outlet is sprayed on the outer surface of the outlet at the area delimited by the guide cylinder. In addition, the liquid flowing out of the outer surface of the discharge head is led to the desired location by means of the walls of the guide cylinder 5 for removal. The term "in the direction of the outlet" means that the space 35 delimited by the guide cylinder 5 is tight in the opening direction of the outlet so that

OhjauslieriO 5 voidaan edullisesti muodostaa j atteenpolttorununun 1 poistopaan kiinteaksi osaksi. jaahdytysnesteena voidaan kayttaa esimerkiksi vetta, jolloin putkisto ja suutinvaiineet 4 voi-5 daan yhdistaa laitoksen painevesiverkkoon. Jaahdytysveden lampOtila voi olla esimerkiksi noin 45°C.5 92435 because you do not run into the combustion chamber. The guide cylinder 5 can advantageously be formed as an integral part of the outlet of the waste incinerator 1. For example, water can be used as the cooling liquid, in which case the piping and nozzle materials 4 can be connected to the plant's pressurized water network. The cooling water temperature can be, for example, about 45 ° C.

Kuvion 2 sovitelma on esimerkki ratkaisusta, jota voidaan kayttaa vanhoissa jo olemassa olevissa uuneissa, ts. kuvion 2 mukainen sovitelma asennetaan kuvion 1 mukai-10 sen ilmapuhallusjarjestelyn tilalle. OhjauslieriO 5 voidaan valmistaa metallilevysta esimerkiksi hitsaamalla. On sel-vaa, etta kuviossa 2 on esitetty ainoastaan osa ohjauslie-riOsta, todellisuudessa OhjauslieriO 5 ymparOi uunin pois-topaata kuten edelia on esitetty. OhjauslieriOn jaikipolt-15 tokammion puoleinen paa on tehty nestetiiviiksi, jolloin jaahdytysnesteen paasy esimerkiksi jaikipolttokammioon 2 on estetty. Uunin poistopaan pinnalta valunut neste virtaa ohjauslieriOn ulointa sisapintaa pitkin takaisin esimerkiksi sopivaan kouruun tai altaaseen 6, joista se voidaan joko 20 poistaa tai kayttaa uudelleen. Takaisin virtaavan nesteen virtaus on esitetty kuviossa 1 nuolten avulla.The arrangement of Figure 2 is an example of a solution that can be used in old pre-existing furnaces, i.e. the arrangement of Figure 2 is installed in place of the air blowing arrangement of Figure 1. The guide cylinder 5 can be made of a metal plate, for example by welding. It is clear that only a part of the guide cylinder is shown in Fig. 2, in fact the guide cylinder 5 surrounds the outlet of the furnace as shown above. The stem on the stem chamber side of the control cylinder is the yak combustion-15, which is made liquid-tight, whereby the ingress of coolant into the yak combustion chamber 2, for example, is prevented. The liquid spilled from the surface of the furnace outlet flows back along the outermost inner surface of the guide cylinder back to, for example, a suitable trough or basin 6, from which it can either be removed or reused. The flow of backflow is shown in Figure 1 by arrows.

Kuten kuviosta 2 voidaan nahda, pyOrivan uunin 1 ja jaikipolttokammion 2 vaiinen rako on tiivistetty sopivien tiivisterakenteiden 7 avulla. Edelia mainittu tiivistys a 25 voidaan toteuttaa yksinkertaisella tavalla. On huomattava, etta keksinnOn mukaisen tiiviin poistopaarakenteen avulla pystytaan eliminoimaan aiempien ratkaisujen haitalliset paastot, silia jaahdytysvaiiaine ei vuoda keksinnOssa pro-sessiin.As can be seen in Figure 2, the silent gap between the rotary kiln 1 and the combustion chamber 2 is sealed by means of suitable sealing structures 7. The aforementioned sealing a 25 can be implemented in a simple manner. It should be noted that the compact exhaust structure according to the invention makes it possible to eliminate the harmful fasts of the previous solutions. The Silia cooling medium does not leak into the process in the invention.

30 Kuvioon 2 on merkitty selvyyden vuoksi uunin sisalla • vallitseva lampOtila 1300°C, jaikipolttokammion sisalla vallitseva lampOtila 1050°C ja paine 4-40 mmVp, seka jaahdytysnesteen lampOtila 45°C.30 For the sake of clarity, Figure 2 shows the temperature inside the furnace • 1300 ° C, the temperature inside the combustion chamber 1050 ° C and the pressure 4-40 mmVp, as well as the temperature of the coolant 45 ° C.

Kuvion 3 sovellutusmuoto vastaa olennaisesti kuvion 35 2 sovellutusmuotoa. Erona on ainoastaan se, etta kuvion 3 6 92435 sovellutusmuoto on tarkoitettu uusien polttouunien yhtey-teen. Kuviossa 3 on kaytetty vastaavissa yksityiskohdissa samoja viitenumerolta kuin kuviossa 2. Toiminnaltaan kuvion 3 sovellutus vastaa kuvion 2 sovellutusta, erot ovat lahin-5 nS konstruktiivisia.The embodiment of Figure 3 substantially corresponds to the embodiment of Figure 2. The only difference is that the embodiment of Fig. 3 6 92435 is intended for new incinerators. In Fig. 3, the same reference numerals as in Fig. 2 have been used in corresponding details. In operation, the embodiment of Fig. 3 corresponds to the embodiment of Fig. 2, the differences being closest to 5 nS constructive.

Edelia esitettyja sovellutusesimerkkeja ei ole mi-tenkaan tarkoitettu rajoittamaan keksintoa, vaan keksintoa voidaan muunnella patenttivaatimusten puitteissa taysin va-paasti. Nain olien on selvaa, etta keksinnOn mukaisen sovi-10 telman tai sen osien ei vaittamatta tarvitse olla juuri sellaisia kuin kuvioissa on esitetty, vaan toisenlaisetkin ratkaisut ovat mahdollisia. On esimerkiksi selvaa, etta jatteenpolttorummun poistopaan ulkopinta voidaan muodostaa millaisesta terasrakenteesta tahansa, kuvioiden ratkaisut 15 eivat ole ainoita mahdollisia. Olennaista on ainoastaan se, etta Jaahdytysneste ruiskutetaan poistopaahan niin, etta se jaahdyttaa poistopaata. Ruiskutus voi tapahtua esimerkiksi poistopaan terdsrakenteen pinnalle jne. Jaahdytysnesteen ei myOskaan vaittamatta tarvitse olla vetta, vaan muidenkin 20 sopivien aineiden kayttdi yksinaan tai vesiseoksina on mah-dollista.The application examples presented above are in no way intended to limit the invention, but the invention can be modified completely freely within the scope of the claims. Thus, it is clear that the arrangement according to the invention or its parts do not necessarily have to be exactly as shown in the figures, but other solutions are also possible. For example, it is clear that the outer surface of the waste incineration drum outlet can be formed of any kind of steel structure, the solutions 15 of the figures are not the only ones possible. All that matters is that the coolant is injected into the discharge pan so that it cools the discharge pan. The spraying can take place, for example, on the surface of the exhaust structure, etc. Of course, the coolant does not necessarily have to be water, but the use of other suitable substances alone or in aqueous mixtures is also possible.
