The invention discloses a phenol condensation layering collecting tower which comprises a tank type tower body, a condensation guide tube and a liquid level control valve, wherein a condensation tank body is arranged inside the inner cavity of the tank type tower body; a phenol collecting tube is arranged at the bottom of the tank type tower body; a waste liquid discharge tube is arranged at the top of the tank type tower body; the condensation guide tube is arranged at the center of the inner cavity of the condensation tank body; the top end of the condensation guide tube extends outwards from the top plate of the tank type tower body; a condensation casing is arranged at the periphery of the condensation guide tube; a guide baffle is arranged at the bottom end of the condensation guide tube; the liquid level control valve is connected with the phenol collecting tube and is provided with a liquid level switch and a liquid level sensor. According to the phenol condensation layering collecting tower disclosed by the embodiment of the invention, the condensation tank body and the condensation guide tube are adopted to cool a phenol mixed liquid inside the tank type tower body, the liquid level control valve is adopted to control that the discharge amounts of phenol stoste and combined water is equal to the feeding amount of the phenol mixed liquid, then the phenol stoste can be continuously delivered out through the phenol collecting tube, and normal production of a salt forming reaction kettle is not affected, therefore, the phenol condensation layering collecting tower is reasonable in structure and simple to operate and control, and the production efficiency of the salt forming reaction kettle can be effectively improved.
