The utility model relates to a temperature control device for a nitrogen return pipeline of a cyclone separator. The temperature control device is characterized in that a heater and a temperature controller are arranged at the front end of a dry slice conveying pipeline and positioned at an outlet position of a conveying fan, the heater is used for heating nitrogen, an over-temperature detection port of the temperature controller is positioned at an outlet of the heater, and electric heating tubes are uniformly and fixedly distributed in the heater. Therefore, the temperature of the nitrogen can be kept constant. The temperature control device has the advantages that the temperature change of a tackifying slice due to the fact that big day-night temperature difference in the north of China leads to the temperature change of delivered nitrogen along with day-night temperature change can be eliminated to the maximum limit, conveying day-night air temperature of the tackifying slice is constant to keep the tempe
