AI Technical Summary
During the operation of a distillation column, the heat and waste heat at the top of the column are difficult to recover and utilize effectively, resulting in high energy consumption and increased production costs.
The system employs a preheater and heat pump structure, connecting to the main body of the distillation column via insulated pipes. It recovers heat energy from gaseous materials to preheat the raw materials and converts it into useful heat energy to heat the liquid mixture at the bottom of the column, reducing the need for external heat sources. At the same time, it reduces heat loss and accelerates the condensation rate of gaseous materials through insulated and heat dissipation pipes.
Effective recovery and utilization of thermal energy reduces the energy demand for heating raw materials, lowers energy consumption, and improves the working efficiency of distillation columns.
