Abstract

The invention discloses a total heat and latent heat recovery type multi-effect vacuum evaporation and concentration device. A heating chamber and an evaporation chamber are respectively divided into first-stage and second-stage heating chambers and evaporation chambers, and to-be-evaporated feed liquid is fed into a heated layer of the heating chamber by a pipeline; the upper end of a water reception machine is connected with a steam outlet of the second-stage evaporation chamber, a reflow horizontal pipe is arranged between the lower end of the left side of the water reception machine and the second-stage heating chamber, steam and steam condensation water discharged from the second-stage evaporation chamber and a heating layer of a second-stage heater are subjected to steam-water separation in the water reception machine, so that secondary steam and steam condensation water are obtained; and a steam recycling device comprises a vacuum pump and a circulating pipe, the separated secondary steam is pressurized and pumped in a heating layer of the first-stage heating chamber by the vacuum pump so as to provide all or part of a heat source for the first-stage heating chamber. According to the device, secondary steam produced in the process of heating evaporation is pressurized and pumped in the first-stage heating chamber and is used as all or part of heat of the first-stage heating chamber, so that energy is saved, and the recovery of latent heat in negative-pressure secondary steam is realized, so that circulating cooling water for cooling the secondary steam can be saved.

Description

technical field [0001] The invention relates to a multi-effect vacuum evaporation concentration device, in particular to a total heat and latent heat recovery type multi-effect vacuum evaporation concentration device. Background technique [0002] The multi-effect vacuum evaporation and concentration device is the commonly used evaporation and concentration equipment at present. It is used to evaporate and concentrate the feed liquid. Gas-water separation is carried out in the water tank, and the high-temperature steam condensate obtained after separation enters the condensate collection tank, and then circulating cooling water is injected into the interlayer of the condensate collection tank, the high-temperature steam condensate is cooled and discharged, and the steam obtained after separation is condensed , The cooler is treated as condensed water at room temperature and discharged, and the cooled non-condensable gas is vacuum exhausted or entered into other treatments. T...
