Patent ID: 7731912

Claim:
A device for converting liquid material into solid form by evaporation, drying and calcining comprising a containment vessel adapted to be placed in heat exchange transfer relation with an external source of heat; said containment vessel comprising a fluid inlet; an elongated passageway; a collection chamber; a scrubber; and an exhaust outlet; said fluid inlet adapted for connection to a source of liquid material to be converted; said elongated passageway in fluid communication at one end with said inlet and at the other end with said collection chamber, and in heat transfer relation with said external source of heat whereby said liquid material flowing in said passageway is converted into a gaseous phase and a concentrated liquid phase; means for directing said gaseous phase from said passageway into said collection chamber and for directing said concentrated liquid phase from said passageway onto the walls of said collection chamber; said walls of said collection chamber being in heat transfer relation with an external source of heat, whereby said concentrated liquid phase is converted into a gaseous phase and calcined solid material in said collection chamber; said exhaust outlet being in fluid communication with said collection chamber for conducting said gaseous phase out of said containment vessel; said scrubber being disposed in said containment vessel between said collection chamber and said exhaust outlet for removal of aerosols and particulate matter entrained in said gaseous phase.
