The invention discloses a high-purity cyclohexanol purification system and method. The purification system comprises a first purification system and a second purification system, wherein the first purification system comprises a hydration reactor, a separator, a first rectifying column and a second rectifying column which are arranged sequentially; a heater is arranged between the first rectifyingcolumn and the second rectifying column; a first heat exchanger is arranged at the top of the second rectifying column, and the hydration reactor, the separator, the first rectifying column, the heater and the second rectifying column are connected through pipelines; the second purification system comprises a third rectifying column and a fourth rectifying column; a second heat exchanger is arranged at the top of the fourth rectifying column, and a third heat exchanger is arranged on one side of the fourth rectifying column. Through deep processing of cyclohexanol mixed products, the problemof low purity of cyclohexanol produced with an existing purification method is solved, cyclohexanol with the purity of 99.8%-99.98% can be obtained with the purification method, and the purity of cyclohexanol is greatly improved.
