The invention discloses an energy-saving and environment-friendly lime kiln for recycling waste heat of smoke. The energy-saving and environment-friendly lime kiln comprises a kiln body provided with a heat insulation layer, a hearth is arranged in the kiln body, an automatic feeding port is formed in the top of the hearth, an automatic ash discharging port is formed in the lower end of the hearth, and an annular smoke outlet flue is arranged at the top of the hearth. The energy-saving and environment-friendly lime kiln is characterized in that the smoke outlet flue is communicated with a desulfurization dust remover through a fan via a heat exchanger, an air inlet and an air outlet are formed in the heat exchanger, and the air outlet is communicated with an air inlet in the lower portion of the hearth through a fan. The temperature of air entering the hearth is increased through to heat exchange, oxygenated combustion supporting is promoted, the kiln temperature can be rapidly increased, an obvious energy-saving effect can be achieved, and the technical problem that in the prior art, waste heat of high-temperature smoke discharged out of a smoke outlet flue is not fully utilized is solved.
Description
technical field [0001] The invention belongs to the technical field of energy-saving and environment-friendly lime kilns, and relates to an energy-saving and environment-friendly lime kiln for recycling flue gas waste heat. Background technique [0002] The lime kiln of the prior art includes a furnace body provided with an insulating layer, a furnace body is provided with a furnace, the top of the furnace is provided with an automatic feeding port, the lower end is provided with an automatic ash discharge port, and the top of the furnace is provided with an annular flue outlet. The flue is connected with the desulfurization and dust collector through the fan. The kiln with this structure is energy-saving and environmentally friendly, but the waste heat of the high-temperature flue gas discharged from the flue is not utilized, and it is directly discharged into the air through the desulfurization and dust collector for waste. Contents of the invention [0003] The purpose...
