The invention provides a safe and environment-friendly rotary barbecue device. According to the device, barbecue is heated uniformly, oil drops can be prevented from falling on a heating device and producing a large amount of cooking fume, little cooking fume is produced, the barbecue cannot be scorched, and the device is beneficial to human health. Meat can be heated in multiple directions of theupper surface and the side surface, is uniformly roasted, is relatively far away from a heat source and cannot be over roasted or scorched, workload of manual operation is low, and the roasted meat tastes good. An exhaust fan is arranged in a fume exhaust cover, a cooking fume suction port is formed in the lower end surface of the fume exhaust cover, a waste gas cleaning device sequentially comprises an adsorption box, a gas filter box and a modified fiber box, the boxes are communicated to form a barbecue tail gas cleaning system, smoke tail gas emitted in the barbecue process can be cleanedand filtered in sequence, emission of hazardous substances in the tail gas is greatly reduced, so that smoke is effectively collected, cleaned and filtered, and environmental pollution is reduced.
