The invention relates to the field of ceramic product production equipment and facilities, in particular to an annular full-automatic wax discharging energy-saving environment-friendly tunnel kiln. The annular full-automatic wax discharging energy-saving environment-friendly tunnel kiln comprises a kiln foundation, a kiln car, a kiln car running system, a combustion system, a fan pipeline system and a control system, wherein the kiln foundation is in an annular shape, a loading and unloading area notch is reserved in the kiln foundation, a wax discharging section, a preheating temperature rising section, a high-temperature sintering section and a cooling section are sequentially arranged in the annular direction, and a loading and unloading area is disposed between the starting end of thewax discharging section and the end point end of the cooling section. The tunnel kiln with an annular structure is adopted, so that the occupied area is small, the space is saved, and the investment cost is reduced. The kiln car runs on an annular track in a circulating mode, and an outer rail turntable is avoided, so that the self heat storage capacity of the kiln car is not easy to lose, the operation is stable, and the loading and unloading is convenient. The tunnel kiln is novel in structure, high in thermal insulation performance, low in energy consumption, high in heat efficiency, and good in product quality, and meets the requirements of energy conservation and environmental protection.
