Efficient energy-saving heat exchange device

The utility model relates to an efficient energy-saving heat exchange device, and belongs to the technical field of energy saving and consumption reduction of chemical machinery equipment. The efficient energy-saving heat exchange device comprises a heat exchange kettle, a circulating pump, a motor, a cooling/warming device, a temperature sensor, an intelligent temperature controller and a frequency converter. The temperature sensor is arranged in the heat exchange kettle and connected with the intelligent temperature controller through a signal line, and transmits temperature signals to the intelligent temperature controller in real time. The intelligent temperature controller is electrically connected with the frequency converter and converts the temperature signals into electric signals to be transmitted to the frequency converter. The frequency converter is electrically connected with the motor. The temperature control theory is applied to chemical equipment, the automation control degree is high, production efficiency is high, the technological process is simple, and operation is easy; in the working process, the rotating speed of the motor is adjusted in real time by making full use of the frequency converter according to requirements, the temperature needed for chemical reactions is guaranteed, the power of a cooling water pump and a heating oil pump is reduced or increased, the power loss is greatly reduced, and therefore energy consumption is reduced.
