The invention discloses a waste heat recovering system for a high-temperature ceramic roller kiln. The waste heat recovering system comprises the ceramic roller kiln and a recovering device; the ceramic roller kiln comprises a high-temperature area, a middle-temperature area and a cooling area, and the recovering device comprises a recovering chamber, a temperature sensor control switch, an upperexhaust fan, a lower exhaust fan and a heat-insulating pipeline; the recovering device is connected with the middle-temperature area and arranged on the periphery of the cooling area, and the side ofthe recovering chamber of the recovering device is provided with a roller opening; and the upper end and the lower end of the recovering chamber are provided with the upper exhaust fan and the lower exhaust fan correspondingly, and the heat-insulating pipeline is arranged on one side and the bottom of the upper exhaust fan. The recovering chamber is closed, the roller opening is only formed in oneside of the recovering chamber, the temperature of the recovering chamber can be sensed by the temperature sensor control switch, and when the temperature of the recovering chamber is lower than theset temperature, the recovering system is stopped by the temperature sensor control switch.
