Abstract

FIELD: chemical industry and heat engineering. SUBSTANCE: distiller has cylindrical casing 1 with inlet and outlet pipes, evaporator 4 mounted coaxially in spaced relation to casing wall, cylindrical heater 5 positioned within evaporator in spaced relation to evaporator wall, fan mounted in upper part of casing 1, condenser attached to casing inner surface and condensate collector. Pipe communicating upper part of condenser 6 with evaporator 4 is tangentially introduced into evaporator 4. Basic liquid delivered into evaporator 4 continues its rotational motion over its inner surface. While being heated, liquid is urged from surface of heater 5 to define vapor padding which is continuously movable from the bottom to the top. Vapor is discharged into space between evaporator 4 and condenser 6, on which it is condensed and from which it is delivered into condensate collector. Fan 7 intensifies conveyance of gas-vapor mixture and maintains low pressure above evaporating surface. EFFECT: increased efficiency and improved quality of condensate. 1 dwg

Claims (1)

Usage: in processes and apparatuses of chemical technology, chemical-technological and heat power processes, in particular in boiler plants of thermal power plants, as well as for distillation and increase the concentration of solutions. Objective: improving the performance of the distiller and improving the quality of the resulting condensate. The inventive distiller contains a cylindrical housing 1 with inlet and outlet nozzles located in the housing of the evaporator 4 mounted coaxially with a gap, a cylindrical heater 5 mounted with a coaxial gap in the evaporator, a fan located in the upper part of the housing, a condenser mounted on the inner surface housing 1, and a condensate collector. A pipe connecting the upper part of the condenser 6 to the evaporator 4 is introduced tangentially into the evaporator, and the initial liquid entering the evaporator continues to rotate along its inner surface. When heated, it is "squeezed" from the surface of the heater 5, forming a "steam jacket", continuously moving from the bottom up. The steam is discharged into the gap between the evaporator 4 and the condenser 6, on which it condenses, and enters the condensate collector. The acceleration of the transportation of the gas mixture and maintaining the vacuum above the evaporation surface is enhanced by a fan 7. 1 ill.
