Purification and impurity removal system for cyclohexanol production process by hydration method

The utility model provides a purification and impurity removal system for a cyclohexanol production process by a hydration method, which comprises a first rectifying tower connected with a hydration reactor so as to enable an enol oil phase in the hydration reactor to enter the first rectifying tower; the heavy oil evaporator is connected with the tower kettle liquid outlet of the first rectifying tower, so that the tower kettle liquid separated by the first rectifying tower enters the heavy oil evaporator; the cooling assembly is connected with the heavy oil evaporator, so that a gas phase evaporated by the heavy oil evaporator enters the cooling assembly to be condensed; the second rectifying tower is connected with the cooling assembly and used for enabling the liquid phase in the cooling assembly to enter the second rectifying tower; the filtering device is connected with the heavy oil evaporator and is used for enabling the cyclohexanol waste liquid in the heavy oil evaporator to enter the filtering devi
