Abstract

SE DESCRIBEN UN METODO Y APARATO PARA PONER EN CONTACTO PARTICULAS SOLIDAS Y UN FLUIDO. SE PULVERIZA UN LIQUIDO EN FORMA DE GOTAS LIQUIDAS DESDE LA PUNTA DE DESCARGA DE UNA BOQUILLA (50) A PARTICULAS SOLIDAS CALIENTES QUE PASAN ASCENDENTEMENTE EN UNA TUBERIA VERTICAL (23). SE FORMA UN TUBO VENTURI EN LA TUBERIA, Y EL TUBO VENTURI TIENE UNA PARTE DE ENTRADA QUE ES ASCENDENTEMENTE CONVERGENTE AL CUELLO Y UNA PARTE DE SALIDA QUE ES ASCENDENTEMENTE DIVERGENTE DEL CUELLO. LA PUNTA DE LA BOQUILLA (50) ESTA SITUADA DE TAL FORMA RELATIVA AL TUBO VENTURI QUE LAS GOTAS DE LIQUIDO COMIENZAN LA EVAPORACION, DEBIDO A LA TRANSFERENCIA DE CALOR DESDE LAS PARTICULAS SOLIDAS CALIENTES, NO MAS LEJOS ASCENDENTEMENTE (RELATIVAS A LA DIRECCION DE MOVIMIENTO DE LAS PARTICULAS SOLIDAS EN LA PARTE SUPERIOR DE LA TUBERIA (23)) QUE EL CUELLO DEL TUBO VENTURI, POR LO CUAL HAY UN ALTO GRADO DE TURBULENCIA QUE CAUSA UN BUEN MEZCLADO DE LAS PARTICULAS Y EL VAPOR DESCENDENTEMENTE DEL CUELLO DEL TUBO VENTURI. LA MEZCLA DEPARTICULAS Y VAPOR SALIENDO DE LA PARTE DE SALIDA DEL TUBO VENTURI ESTA BIEN MEZCLADA Y LAS PARTICULAS ESTAN SUSTANCIAL Y UNIFORMEMENTE MEZCLADAS CON EL VAPOR EN PLANOS RADIALES DE LA TUBERIA (23) CORRIENTE ABAJO DEL TUBO VENTURI. LA ENERGIA DE LAS GOTAS QUE ENTRAN EN LA TUBERIA (23) DESDE LA BOQUILLA (50) ES COMPARTIDA CON LAS PARTICULAS EN LA CORRIENTE ASCENDENTE DEL CUELLO Y LAS ACELERA A UNA MAYOR VELOCIDAD EN LA TUBERIA (23). EL METODO Y APARATO SE PUEDEN EMPLEAR PARA MEZCLAR UNA ALIMENTACION DE HIDROCARBONO CON PARTICULAS DE PRESOPIROLISIS CATALITICA ACTIVA EN CALIENTE EN UNIDADES DE PRESOPIROLISIS CATALITICA O PROCESO PARA REDUCIR LAS PRODUCCIONES DE GAS LIGERO Y COQUE Y PARA INCREMENTAR LAS PRODUCCIONES DE PRODUCTOS DE HIDROCARBONO MAS VALIDOS.
