Abstract
"DISPOSITIVO PARA LIBERAçãO". A invenção diz respeito a um dispositivo para liberação, de um tubo alimentador (10), de um agente redutor, que foi previamente convertido de uma primeira fase em uma segunda fase e, em seguida, de volta para a primeira fase, onde o tubo é usado para alimentar,o agente redutor na segunda fase a um catalisador SCR inserido na linha de descarga de um motor a diesel. O dispositivo é uma válvula (12) para dosagem do agente redutor na segunda fase. A sede fixa da válvula ou a face móvel da válvula (16) se encostando e apoiando na mesma, quando a válvula (12) se encontra na posição fechada, é na forma de um elemento condensador controlado por um controlador e previsto para atuar como um coletor criogênico inserido no tubo alimentador (10), quando controlado de maneira correspondente. O elemento condensador, ou o elemento de válvula unido ao mesmo, é aquecível sob controle de um controlador."DEVICE FOR RELEASE". The invention relates to a device for releasing a feeder tube (10) of a reducing agent which was previously converted from a first phase to a second phase and then back to the first phase, where the tube It is used to feed the reducing agent in the second phase to an SCR catalyst inserted into the discharge line of a diesel engine. The device is a valve (12) for metering the reducing agent in the second phase. The fixed valve seat or the movable face of the valve (16) abutting and abutting when the valve (12) is in the closed position is in the form of a condenser element controlled by a controller and intended to act as a cryogenic collector inserted into the feeder tube (10) when controlled accordingly. The condenser element, or the valve element attached thereto, is heatable under the control of a controller.
