Solid waste refers to solids, semisolids, and gaseous objects placed in containers that lose their original utility or that are discarded or discarded without losing utility during production, life, and other activities, as well as objects, substances, and articles that are subject to waste management by law and administration. Solid waste treatment is a process of reducing its volume and accelerating its natural purification by physical means (e.g., pulverization, compression, drying, evaporation, incineration, etc.) or biochemical actions (e.g., oxidation, digestion, decomposition, absorption, etc.) and thermal pyrolysis gasification. In the process of solid waste treatment, a rotary kiln is generally adopted for incineration, and a corresponding feeding device is required to be used for conveying the solid waste into the rotary kiln in the incineration process. The rotary kiln burns the solid waste and then generates a large amount of flue gas, and the temperature of the flue gas is about 1150 ℃, so that the flue gas usually contains a large amount of heat and is directly discharged, the air is polluted, and the heat is wasted. For this reason, CN208983593U discloses a rotary kiln exhaust-heat boiler, make through setting up the fixed shell, a fixed section of thick bamboo, driving motor, the dwang, the (mixing) shaft, inlet tube and outlet pipe make and utilize the flue gas waste heat, drive the stirring through driving motor and rotate, make to heat water, thereby be convenient for use hot water, the stirring process makes water be heated evenly, and when this exhaust-heat boiler is used for the flue gas that produces solid waste incineration to utilize, because flue gas heat is too big, after the flue gas heats water, the residual heat is still very big, direct discharge is still can produce the waste of heat, for we have developed a special heat secondary recycle device of flue gas that the rotary kiln burns in the solid waste treatment process.
