Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of distillation, in particular to a high-efficiency energy-saving distillation device. Background Art
[0002] Distillation is usually carried out in a distillation tower, where the gas and liquid phases are in countercurrent contact to conduct interphase heat and mass transfer. The volatile components in the liquid phase enter the gas phase, and the non-volatile components in the gas phase are transferred to the liquid phase, so that almost pure volatile components can be obtained at the top of the tower, and almost pure non-volatile components can be obtained at the bottom of the tower. The reboiler is one of the key equipment in the distillation tower. Its function is to heat the bottom residue of the tower again to vaporize it, so as to provide upward-flowing steam, thereby maintaining the mass and heat balance in the tower.
[0003] Since the reboiler usually uses steam or heat transfer oil as the heat source, these heat sources will drop in temperature after transferring heat to the residue, but the heat will not disappear too much. These heat sources carrying heat will directly enter the circulating heating equipment, which will undoubtedly cause heat waste. The waste of energy directly leads to an increase in the operating cost of the entire distillation process, which has an adverse impact on the economic benefits of the enterprise. To this end, we provide a high-efficiency and energy-saving distillation device to solve the above problems. Utility Model Content
