Abstract
L'invenzione riguarda un dispositivo per la depurazione da metalli pesanti e scorie del gas di sintesi generato da rifiuti di raffineria. Al di sotto di un noto reattore per gas di sintesi (1) è disposto un dispositivo di deflessione del gas (3, 4), nel quale il gas di sintesi caldo fluente verticalmente verso il basso viene deviato nella direzione orizzontale e successivamente giunge in un radiatore a recupero di calore (2) di per se noto. Internamente al dispositivo di deflessione (3, 4) è incorporata una parete di deviazione (5) ceramica, intorno alla cui estremità inferiore il gas di sintesi viene guidato. Poiché il gas di sintesi ricavato da rifiuti di raffineria presenta una percentuale relativamente elevata di metalli pesanti e scorie, esiste il pericolo che queste particelle contaminano le pareti di scambio del radiatore a recupero di calore (2) collegato a valle. Secondo l'invenzione, i metalli pesanti e le scorie vengono separati dalla corrente di gas nel dispositivo di deflessione (3, 4). Le particelle di metalli pesanti e scorie presenti sotto forma liquida internamente al gas caldo seguono il percorso verso il basso in conseguenza del loro peso specifico più elevato rispetto al gas, e giungono in una vasca di raffreddamento rapido ad acqua (7) disposta sotto al dispositivo di deflessione (3, 4), nella quale essi assumono forma granulare. Il gas di sintesi depurato da metalli pesanti e scorie nel radiatore a recupero di calore (2) collegato a valle.
