Description

Technical Field

[0001] The utility model relates to the technical field of fractionation, in particular to a fatty acid fractionation tower. Background Art

[0002] Fractional distillation is the process of heating a mixture and evaporating the different components of the mixture into gaseous state according to their boiling points. Since the boiling points are different, the condensation points of the evaporated gaseous substances in the mixture are also different. Then, the gaseous substances are condensed and separated into relatively pure single substances at different temperatures.

[0003] After searching the patent document with the publication number CN 220443212 U, it is found that two spirally intertwined first condenser tubes and second condenser tubes are connected head to tail and placed at the center of a condensation tower, and then condensate is fed into the first condenser tube and discharged from the second condenser tube. During this process, the entire condensate follows the first condenser tube and flows along the upper side of the condensation tower to the lower side thereof, and then enters the second condenser tube and flows from the lower side of the condensation tower to the upper side thereof before being discharged, so that the temperatures at both ends of the first cooling tube and the second cooling tube tend to be consistent;

[0004] In the patent document, if the two condensers adopt the above structure, the temperature in the entire cooling structure will be consistent. According to the structural principle of the condensation tower, the temperature at the top of the condensation tower will be lower than the temperature on its lower side. Therefore, after the coolant passes through the second cooling tube, its temperature may be higher than the temperature on the top of the condensation tower. The higher temperature in the second cooling tube will increase the temperature of the coolant that has just entered the first cooling tube, which may affect the condensation effect of the entire gaseous substance and also affect the discharge amount of the entire distillation tower.

The connecting pipe 42 is used to connect the liquid inlet pipe 31 and the liquid outlet pipe 34 of the upper and lower adjacent levels.
