摘要： An internal heat exchange-type distillation column integrally having a recovery section and a concentration section. Heat transmission means is provided on the surface of the concentration section adjoining the recovery section, and the means is received in the recovery section. Steam is directly supplied to the heat transmission means from the concentration section side, heat is transmitted from the means to the recovery section, and after the transmission, condensate liquid is returned to the concentration section. With the structure above, heat in the concentration section is efficiently used in the recovery section. At least one opening/closing section is provided, or the recovery section and the concentration section are separatably constructed, so that the content in the recovery section and the concentration section can be easily exchanged or cleaned, facilitating maintenance.
