The invention discloses a heat pump distillation system in the chemical industry. The heat pump distillation system comprises a distillation tower, a heating tube is arranged in the distillation tower and is connected to a heat pump, a condenser is arranged at the top end in the distillation tower, and a collecting bottle is arranged outside the distillation tower. The distillation tower is further provided with a collector and a separation net device, wherein the separation net device is located above the collector and below the condenser, and the collecting bottle is communicated with the bottom of the collector. Compared with the prior art, the heat pump distillation system in the chemical industry is simple in structure, the principle is easy and convenient to implement, fewer devices are needed, the distillation purpose can be quickly achieved, distilled products are stable in quality, the demand of subsequent production processes can be met, and the production cost is reduced.
Description
technical field [0001] The invention relates to a distillation system, in particular to a heat pump distillation system in the chemical industry. Background technique [0002] Distillation is a thermodynamic separation process, which utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low boiling point components, and then condenses to separate the entire components. It is a unit operation process of evaporation and condensation. union of operations. Compared with other separation methods, such as extraction, etc., its advantage is that it does not need to use other solvents other than system components, so as to ensure that no new impurities will be introduced. Refers to the mass transfer process that uses the difference in volatility of each component in a liquid mixture to separate components. An evaporation and condensation process in which the vapor generated by the boiling of the liquid is introduced int...
