According to the technical scheme, the RTO high-temperature
incineration environment-friendly equipment comprises an incinerator, a gas inlet structure connected with external
tail gas emission equipment is arranged on one side of the incinerator, and a gas outlet
pipe used for discharging gas is arranged on the other side of the incinerator. The gas inlet structure comprises a gas inlet
pipe communicating with the incinerator and a connecting shell rotationally arranged on the gas inlet
pipe, the gas inlet pipe is connected with the connecting shell in a sealed mode, a plurality of sealing rings which are different in inner
diameter and connected with
tail gas emission equipment are arranged in the connecting shell, and the lengths of the sealing rings are different. And the smaller the inner
diameter is, the longer the sealing ring is. According to the utility model, the gas inlet structure is in threaded connection with the
tail gas emission equipment to realize convenient
assembly and disassembly, and meanwhile, the internal threads on the plurality of sealing rings with different inner diameters are in threaded connection with the tail gas emission equipment, so that the tail gas emission equipment with different pipe diameters can be connected, and the application range of the equipment is further expanded.
