专利汇可以提供Evaporators专利检索，专利查询，专利分析的服务。并且An evaporator comprises an enclosure which receives liquid for evaporation, and in said enclosure there is set up by rotor means a substantially vertical rotating cylindrical vortex column of the liquid surrounded by a gaseous medium. The column is either contained in a sleeve which rotates with the column and the rotor, or has an outer surface, without any rigid surround, in open contact with the gaseous medium. The column is vaporized by heat transferred to it from the gaseous medium, and the vapor is conducted from the enclosure. Additional liquid is fed into the enclosure to replace that lost by evaporation and thus to maintain the vortex column.，下面是Evaporators专利的具体信息内容。

权利要求

1. A method of effecting liquid evaporation, comprising substantially filling a closed space with a liquid to be evaporated, rotating rotor means in the liquid to set up a vortex in the liquid, removing some of the liquid forming the more remote peripheral zones beyond the rotor means from the closed space and simultaneously replacing the removed liquid by a hot gaseous medium in order to leave in said closed space a substantially vertical rotating liquid vortex column having substantially its whole outer surface in open contact with the gaseous medium in the remote zones in the closed space, applying heat by said gaseous medium to the outer surface of said liquid vortex column in order to form vapor therefrom, removing said vapor and gaseous medium from said remote zones in said closed space, removing vapor from the inner surface of said liquid vortex column, and supporting the liquid vortex column by the difference of gaseous pressures acting on the outer and inner surfaces of the liquid vortex column.

2. A liquid evaporating device comprising an enclosure having a cover, means for charging said enclosure with liquid to be evaporated, rotor means including vanes for generating in said enclosure a substantially vertical, rotating, cylindrical vortex column of said liquid, said rotor means having a collecting chamber for vapor removal from within said liquid vortex column fixed to and rotatable with said rotor means and extending through said cover, said liquid column rising from the base of said enclosure, means for introducing a gaseous heat-transfer medium into said enclosure surrounding said liquid column, and thereby heating the outer surface of said liquid vortex column, in order to form vapor therefrom, means for leading away said vapor from said collecting chamber, and means for removing liquid frOm a lower peripheral portion of said enclosure thereby to aid in establishing in said enclosure said liquid vortex column without any surrounding sleeve for containing said liquid vortex column.

3. A device as claimed in claim 2, and means for feeding liquid into said enclosure to replace liquid lost by evaporation from the liquid vortex column thereby to maintain the liquid vortex column.
