Description
Descrizione Description
L' invenzione si riferisce ad un dispositivo at to a smaltire termicamente rifiuti, comprendente una pressa per il rifiuto, un canale riscaldato di gassi freazione, un reattore ad alta temperatura, dal qua le possono essere estratti una massa fusa e gas distillati a bassa temperatura, un dispositivo di raf freddamento brusco ed un dispositivo di depurazione per i gas distillati a bassa temperatura. The invention relates to a device suitable for thermally disposing of waste, comprising a rejection press, a heated gas fractionation channel, a high temperature reactor, from which a melt and low temperature distilled gas can be extracted. , an abrupt cooling device and a purification device for low temperature distilled gases.
Un tale dispositivo è noto dal documento EP-A-0 443 596. Secondo questo, il rifiuto, viene compatta to, senza preventivo trattamento e preventiva classi ficazione, in una pressa sotto elevata pressione, a circa un decimo del volume originario. La balla compatta di rifiuti perviene poi in un canale di gassi ficazione o di distillazione a bassa temperatura, ri scaldato in modo indiretto. Essa viene qui essiccata a circa 600°C, in assenza d'aria, e bruciata in difetto d'aria per ottenere coke di pirolisi. Le balle di rifiuti vengono immediatamente dopo gassificate in un reattore o gassificatore ad alta temperatura, con alimentazione di ossigeno puro, a circa 2000°C. A questa temperatura fondono i componenti minerali e metallici e si decompongono gli idrocarburi e gli al tri componenti organici. La massa fusa viene separa ta. Essa contiene un residuo minerale, vetroso, ed una frazione metallica consistente principalmente in ferro. I gas di distillazione a bassa temperatura o di combustione vengono bruscamente raffreddati in un dispositivo di raffreddamento brusco (Quencher) da 1200°C ad una temperatura di circa 90°C. Si vuole in seguito a ciò impedire la formazione di diossine e furani. Successivamente, i gas della combustione at traversano un sistema di depurazione a più stadi, formatoi da filtri e da lavatori, fino a che essi vengono riciclati nel processo, sotto forma di gas di sintesi combustibile, oppure utilizzati altrimen ti, per esempio per la produzione di energia elettri ca. Il procedimento qui adottato è stato anche reso noto dalla stampa, per esempio dalla "Berliner Morgenpost" del 6 giugno 1993, sotto il nome di prò cedimento "Thermoseleet" . Esso è in concorrenza con il procedimento di combustione in difetto d'aria (EP -C-0 302 310). Such a device is known from document EP-A-0 443 596. According to this, the waste is compacted, without prior treatment and prior classification, in a press under high pressure, to approximately one tenth of the original volume. The compact bale of waste then enters a low-temperature gasification or distillation channel, heated indirectly. It is dried here at about 600 ° C, in the absence of air, and burned in the absence of air to obtain pyrolysis coke. The waste bales are immediately after gasified in a reactor or gasifier at high temperature, with pure oxygen supply, at about 2000 ° C. At this temperature the mineral and metal components melt and the hydrocarbons and other organic components decompose. The melt is separated. It contains a mineral residue, glassy, and a metal fraction consisting mainly of iron. The low temperature distillation or combustion gases are abruptly cooled in a 1200 ° C abrupt cooling device (Quencher) to a temperature of about 90 ° C. As a result, the formation of dioxins and furans is to be prevented. Subsequently, the combustion gases pass through a multi-stage purification system, consisting of filters and washers, until they are recycled in the process, in the form of combustible synthesis gas, or used otherwise, for example for production. of electrical energy approx. The procedure adopted here was also made known in the press, for example by the "Berliner Morgenpost" of 6 June 1993, under the name of the procedure "Thermoseleet". It competes with the low-air combustion process (EP-C-0 302 310).
Riflessioni hanno ora indicato che nel caso del noto dispositivo una quantità di energia termica vie ne persa, senza essere sfruttata, sul oppure nel di spositivo di raffreddamento brusco "Quencher". Nel senso di un miglioramento del noto procedimento per lo smaltimento di rifiuti sarebbe però urgentemente auspicabile uno sfruttamento di questa energia dei gas distillati a bassa temperatura. Oltre a ciò, lo scarico di questa energia nell'ambiente può portare a problemi. Reflections have now indicated that in the case of the known device a quantity of thermal energy is lost, without being exploited, on or in the "Quencher" abrupt cooling device. In the sense of an improvement of the known method for the disposal of waste, it would be urgently desirable to use this energy of the low-temperature distilled gases. In addition to that, the discharge of this energy into the environment can lead to problems.
Alla base dell'invenzione stà perciò il compito di configurare un dispositivo del genere menzionato inizialmente in maniera tale che l'energia dei gas di distillazione a bassa temperatura possa essere sfruttata . The aim of the invention is therefore to configure a device of the kind mentioned initially in such a way that the energy of the low-temperature distillation gases can be exploited.
Questo compito viene risolto secondo l'invenzio ne per il fatto che sono previsti mezzi per scorpora re l'energia termica dei gas distillati a bassa tem peratura This task is solved according to the invention due to the fact that means are provided for separating the thermal energy of the low temperature distilled gases.
a) in corrispondenza del dispositivo di raffreddamen to brusco a) at the abrupt cooling device
b) e/oppure tra il reattore ad alta temperatura ed il dispositivo di raffreddamento brusco b) and / or between the high temperature reactor and the abrupt cooling device
c) e/oppure tra il reattore ad alta temperatura ed il dispositivo di depurazione con integrato dispo sitivo di raffreddamento brusco. c) and / or between the high temperature reactor and the purification device with integrated abrupt cooling device.
L'energia scorporata tramite i menzionati mezzi può essere sfruttata a titolo di esempio nel proces so stesso di smaltimento dei rifuti. Essa può a tito lo di esempio essere utilizzata per la produzione di energia elettrica oppure per il riscaldamento del ca naie di gassificazione. The energy separated by the aforementioned means can be exploited by way of example in the waste disposal process itself. By way of example, it can be used for the production of electricity or for heating the gasification channel.
Preferite configurazioni dell'invenzione sono caratterizzate nelle rivendicazioni subordinate. Preferred configurations of the invention are characterized in the subordinate claims.
Esempi di realizzazione dell'invenzione vengono in appresso illustrati più dettagliatamente in rela zione a due figure. In esse: Examples of embodiments of the invention are illustrated hereinafter in more detail in relation to two figures. In them:
la figura l mostra un dispositivo atto a smalti re termicamente rifiuti con scorporamento dell'ener già direttamente sul Quencher e figure 1 shows a device suitable for thermally disposing of waste with separation of the energy already directly on the Quencher e
la figura 2 mostra un dispositivo atto allo smaltimento termico di rifiuti con scorporamento del l'energia direttamente a valle del reattore ad alta temperatura, nonché con scorporamento dell'energia in una parte combinata Quencher-lavaggio del gas. Figure 2 shows a device suitable for the thermal disposal of waste with separation of the energy directly downstream of the high-temperature reactor, as well as with separation of the energy in a combined Quencher-gas washing part.
Nella figura 1 è mostrato un dispositivo atto a smaltire termicamente rifiuti. Il rifiuto A viene in proposito addotto, attraverso un dispositivo di cari camento 2, ad una pressa 4 dove esso viene compresso sotto elevata pressione per formare balle 6 di rifiu ti. Le balle 6 di rifiuti compresse pervengono poi in un canale 8 di combustione in difetto di ossigeno o di gassificazione. Il riscaldamento esterno di que sto canale 8 di gassificazione è contrassegnato con 10. Dal canale 8 di gassificazione il prodotto soli do o bruciato in difetto di ossigeno F delle balle 6 di rifiuti ed i gas G formatisi, distillati a bassa temperatura, pervengono in un reattore 22 ad alta temperatura, posto direttamente a valle. Il prodotto solido F bruciato in difetto di ossigeno è costituì to per una grossa parte da sostanze contenenti carbo nio. Questo prodotto solido F viene gassificato nel la parte inferiore del reattore 22 ad alta temperatu ra, ad una temperatura di 2000°C. Attraverso un ingresso 38, allo scopo, alla parte inferiore del reat tore 22 ad alta temperatura viene addotto ossigeno puro 02 . Si verifica una combustione o gassificazio ne sottostechiometrica. La massa fusa in tal caso formantesi nel reattore 22 ad alta temperatura è con trassegnata con S. Essa può essere prelevata attraverso uno scarico 40 e raccolta in un recipiente 42. Figure 1 shows a device suitable for thermally disposing of waste. The waste A is in this regard conveyed, through a loading device 2, to a press 4 where it is compressed under high pressure to form bales 6 of waste. The bales 6 of compressed waste then arrive in a combustion channel 8 in lack of oxygen or gasification. The external heating of this gasification channel 8 is marked with 10. From the gasification channel 8 the solid or oxygen deficient product F of the waste bales 6 and the gases G formed, distilled at low temperature, arrive in a high temperature reactor 22, placed directly downstream. The solid product F burned in lack of oxygen is largely made up of substances containing carbon. This solid product F is gasified in the lower part of the high temperature reactor 22, at a temperature of 2000 ° C. Through an inlet 38, for this purpose, pure oxygen 02 is fed to the lower part of the high-temperature reactor 22. Sub-stoichiometric combustion or gasification occurs. The melt thus forming in the high-temperature reactor 22 is designated S. It can be withdrawn through a drain 40 and collected in a vessel 42.
Nella parte superiore del reattore 22 ad alta temperatura i gas G distillati a bassa temperatura vengono sottoposti ad una intima miscelazione. Anche qui, dopo l'aggiunta di ossigeno, ha luogo una combu stione sottostechiometrica. In the upper part of the high temperature reactor 22 the low temperature distilled gases G are subjected to an intimate mixing. Here too, after the addition of oxygen, substoichiometric combustion takes place.
I gas G distillati a bassa temperatura, preleva ti dallo scarico 44 del gas del reattore 22 ad alta temperatura, vengono inviati in un Quencher oppure in un dispositivo 46 di raffreddamento brusco con scorporamento dell'energia, dove essi vengono raffreddati per esempio ad una temperatura di 90°C. A valle di questo dispositivo 46 di raffreddamento bru sco è posto un sistema di depurazione 48. Un ventila tore di aspirazione 50 provvede ad una sufficiente velocità di flusso dei gas G distillati a bassa tem peratura. Dopo la depurazione, i gas G distillati a bassa temperatura possono essere utilizzati per il riscaldamento del sistema di riscaldamento esterno 10 del canale di gassificazione 8 oppure però, per produrre energia. The low-temperature distilled gases G, taken from the high-temperature reactor 22 gas exhaust 44, are sent to a Quencher or an energy-stripping abrupt cooling device 46, where they are cooled for example to a temperature 90 ° C. Downstream of this burnt cooling device 46 there is a purification system 48. A suction fan 50 provides a sufficient flow rate of the low temperature distilled gases G. After purification, the low-temperature distilled gases G can be used for heating the external heating system 10 of the gasification channel 8 or, however, to produce energy.
Sul dispositivo 46 di raffreddamento brusco le condutture di afflusso e di deflusso del liquido Q di Quench sono indicate mediante frecce 52, 54. Di particolare importanza è ora il fatto che il disposi tivo 46 di raffreddamento brusco presenta un mantel lo di raffreddamento 56, in corrispondenza del cui ingresso 58 viene inviato un fluido di raffrddamento K ed in corrispondenza della cui uscita 60 il fluido di raffreddamento K riscaldato viene prelevato ed ad dotto ad un riutilizzo (non meglio mostrato). Il man tello di raffreddamento 56 agisce perciò come uno scambiatore di calore per scorporare l'energia termi ca dei gas G distillati a bassa temperatura. On the abrupt cooling device 46 the inlet and outlet pipes of the Quench liquid Q are indicated by arrows 52, 54. Of particular importance is now the fact that the abrupt cooling device 46 has a cooling jacket 56, in at whose inlet 58 a cooling fluid K is sent and at whose outlet 60 the heated cooling fluid K is withdrawn and sent for reuse (not better shown). The cooling jacket 56 therefore acts as a heat exchanger for separating the thermal energy of the low temperature distilled gases G.
Nella figura 2 è rappresentata una forma di rea lizzazione alternativa per lo scorporamento energeti co nella regione del dispositivo di Quench. Anzitut to è in primo luogo previsto che tra l'uscita 44 del reattore 22 ad alta temperatura ed il dispositivo 46 di raffreddamento brusco sia disposta una caldaia di recupero 62 comprendente per esempio tre scambiatori di calore 64. Gli scambiatori di calore 64 servono anche qui alla scorporazione termica dell'energia. In aggiunta oppure in alternativa può essere previsto che il dispositivo 46 di raffreddamento brusco sia integrato in un dispositivo di depurazione 48 e che in questa combinazione entri uno scambiatore di calore 66 per lo scorporamento dell'energia. Il liquido Q di Quench viene qui fatto passare attraverso due Quencher 70, 72 posti in parallelo, i quali per i gas G distillati a bassa temperatura sono posti in serie. Il circuito di Quench è accennato mediante frecce di ingresso 74 e frecce di uscita 76. Nel cir cuito Quench-liquido si trovano qui ancora un dispo sitivo di pompaggio 78 ed un bacino di decantazione 80. Attraverso lo scambiatore di calore 66 viene qui parimenti scorporata energia termica. Come già rappresentato, questa può essere sfruttata per il processo stesso di smaltimento dei rifiuti. Essa può an che essere addotta ad un altro riutilizzo. Figure 2 shows an alternative embodiment for energetic separation in the region of the Quench device. First of all it is provided that between the outlet 44 of the high temperature reactor 22 and the abrupt cooling device 46 there is a recovery boiler 62 comprising for example three heat exchangers 64. The heat exchangers 64 are also used here. to the thermal separation of energy. In addition or alternatively, provision may be made for the abrupt cooling device 46 to be integrated in a purification device 48 and for a heat exchanger 66 to enter this combination for the separation of the energy. Here the Quench liquid Q is passed through two Quenchers 70, 72 placed in parallel, which for the low-temperature distilled G gases are placed in series. The Quench circuit is indicated by means of inlet arrows 74 and outlet arrows 76. In the Quench-liquid circuit there is again a pumping device 78 and a settling basin 80. It is also separated here by means of the heat exchanger 66. thermal energy. As already represented, this can be exploited for the waste disposal process itself. It can also be used for another reuse.
