As shown in fig. 1 to 3, the recovery cooling device for a rectifying tower provided in this embodiment includes: the rectifying column body 1, outlet duct 2 that the rectifying column body 1 upper end set up is used for discharging the gaseous phase. The rectifying tower body 1 utilizes the property that each component in the mixture has different volatility, namely, the vapor pressure of each component is different at the same temperature, so that light components (low-boiling-point substances) in a liquid phase are transferred into a gas phase, and heavy components (high-boiling-point substances) in the gas phase are transferred into the liquid phase, thereby realizing the purpose of separation. Before cooling treatment is needed, firstly, discharging gas phase remained in the tank from an air outlet pipe 2 to an air inlet pipe 3; as a further scheme, an induced draft fan 211 is arranged on the air outlet pipe 2. Through the setting of draught fan 211, can be faster more thorough pump-out to the residual gas phase in the jar to in entering condenser 4, in condenser 4 gets into rectifying column body 1 through first feed liquor pipe 5 again after liquefying with the residual component of gaseous phase. The recovery liquid that gets into in the rectifying column body 1 falls to the bottom because of gravity, for convenient collection and filtration, as further scheme, the bottom of rectifying column body 1 is provided with stock solution chamber 111, and the upper end of stock solution chamber 111 is provided with first filter screen 112. The recovered liquid is collected in the liquid outlet cavity 111 and then discharged into the circulating water tank 10 from the liquid outlet pipe 8 at the bottom. At this time, the recovered liquid in the circulation tank 10 is discharged to a predetermined container and collected after the drain pipe 18 is opened. At the moment, spray water can be started to flush the inside of the tower, and then residual liquid on structures such as a tower wall, a tower inner partition plate and the like is recovered.
