Problems solved by technology
However, most of the rotary kilns in the prior art are connected to the vent at the kiln tail. When the dangerous incineration is in the preheating stage at the entrance, the supply of oxygen is sufficient, but in the middle stage of the rotary kiln, hazardous waste enters the incineration stage. At this time, it is necessary to A large amount of oxygen supply, but relying solely on the air supply at the kiln tail will often cause insufficient oxygen supply, resulting in insufficient incineration

The invention discloses a rotary kiln with a middle air inlet device. The rotary kiln comprises a kiln body component, a transmission device, the middle air inlet device and a feeding device, wherein the tail of the kiln body component is hermetically connected with the feeding device; the transmission device is installed on the right side of the middle of the kiln body component; and the middle air inlet device is installed in the middle of the kiln body component and located on the left side of the transmission device. After hazardous waste is poured into the feeding device, the hazardous waste slides down in a cavity under the influence of gravity, and enters the kiln body component; the kiln body component is arranged in the mode that the kiln tail position is higher than the kiln head position, and the transmission device can drive a barrel to rotate slowly when the rotary kiln works normally, so that the hazardous waste slides to a kiln head from a kiln tail slowly in the rotating process; and the hazardous waste can be continuously turned over through the rotating action, so that the hazardous waste is combusted more sufficiently. When the hazardous waste reaches the middle of the kiln body component, air enters the middle air inlet device from the middle position, so that sufficient oxygen is provided for incineration, and residues obtained after combustion and smoke are discharged out of the kiln head together.
Description
technical field [0001] The invention relates to the technical field of hazardous waste incineration, in particular to a rotary kiln with an intermediate air inlet device. Background technique [0002] The notice issued by the Ministry of Environmental Protection on the "Technical Policy on Hazardous Waste Pollution Prevention and Control" pointed out: "The incineration of hazardous waste can realize the reduction and harmlessness of hazardous waste, and the residual heat can be recycled. Its useful components are hazardous wastes with a certain calorific value. Explosive wastes are not suitable for incineration disposal", "The incineration of hazardous wastes should adopt the incineration technology based on rotary kilns, and other different types of wastes can be selected according to the types and characteristics of hazardous wastes. Furnace type, encourage the transformation and use of rotary kiln for cement production to supplement or exclusively burn hazardous waste. I...
