The invention relates to a method for
vinasse tube
bank type
drying and
exhaust gas and steam condensed liquid heat recycling. The method comprises the following steps: (1), after centrifuging
vinasse, obtaining a wet
vinasse material and vinasse
clear liquid, and after concentrating the vinasse
clear liquid, feeding concentrated liquid into a concentrated
liquid storage tank; (2), conveying the wet vinasse material and the concentrated liquid to a material return spiral conveyor, conveying the wet vinasse material and the concentrated liquid to a mixing spiral conveyor together, mixing, and after mixing uniformly, feeding the mixture into a tube
bank type
drying machine; (3), feeding saturated steam into the tube
bank type
drying machine, and heating and drying the material mixture in a reverse flow manner so as to obtain a dried material,
exhaust gas and
condensed water; (4), after separating the
exhaust gas by a
cyclone separator, obtaining a separated material and separated exhaust gas, feeding the separated material into the material return spiral conveyor, and cyclically utilizing the separated material; (5), feeding the separated exhaust gas into a sprinkling
tower, washing the exhaust gas, and separately producing secondary steam A and washing water left after heat exchange; and (6), feeding the
condensed water into a
condensed water flash evaporation tank, carrying out
flash evaporation on the condensed water, and separately producing secondary steam B and condensed liquid. The method is simple and reliable, is continuous in running, saves energy, reduces consumption and is safe and environment-friendly.
