The invention discloses a glycerin distillation device. The glycerin distillation device comprises a distillation column, a hot water tank and a superheated water tank, wherein an upper heat exchanger, a lower heat exchanger, an upper receiving disc and a lower receiving disc are arranged in the distillation column; an inlet of the upper heat exchanger is connected with a bottom outlet of the hotwater tank through a pipe, and an outlet is connected with a top inlet of the hot water tank through a pipe; an inlet of the lower heat exchanger is connected with a bottom outlet of the superheated water tank through a pipe, and an outlet is connected with a top inlet of the superheated water tank; the upper receiving disc is arranged between the upper heat exchanger and the lower heat exchanger,and a yellow glycerin discharge port b is formed in the upper receiving disc; the lower receiving disc is arranged below the lower heat exchanger, and a glycerin discharge port c is formed in the lower receiving disc; the bottom outlet of the hot water tank is slightly higher than the outlet of the upper heat exchanger, and the hot water tank is provided with a water inlet i and a hot water outlet j; the bottom outlet of the superheated water tank is slightly higher than the outlet of the lower heat exchanger, and the superheated water tank is provided with a low-pressure steam outlet k and awater inlet l. The glycerin distillation device has the characteristics of simple structure, low manufacture and maintenance cost and convenient and efficient operation.
Description
technical field [0001] The invention relates to biodiesel production equipment, in particular to a biodiesel by-product glycerol distillation device. Background technique [0002] The by-product crude glycerin in the preparation of biodiesel contains impurities such as water, methanol, fatty acid methyl esters, fatty acid soaps, inorganic salts, and pigments. Evaporation, distillation, deodorization, decolorization and other processes are generally used in the refined production of glycerol to produce products that meet national standards; the distillation process is the key, and this process directly determines product quality and benefits. Since the boiling point of glycerin is about 190°C higher than that of water, the distillation production of glycerin generally consists of a distillation column and several heat exchangers. , in order to achieve the purpose of separating glycerol and darker glycerol (commonly known as yellow glycerin) from water. The specific process ...
