Abstract

The invention relates to the technical field of energy-saving environment-friendly lime kilns, in particular to an energy-saving environment-friendly lime kiln with flue gas recycle. Two supports arearranged, a kiln body is connected between the two supports, an ash receiving base is connected with the two supports in a sliding mode, the ash receiving base is located under the kiln body, two ashunloading control parts are symmetrically arranged at the two ends of the ash receiving base, the number of the ash unloading control parts is two, the two ash unloading control parts are connected with the two supports respectively, a feeding control part is arranged on one support, the left end of the ash receiving base is connected with the feeding control part, the upper end of the feeding control part is connected with the kiln body, and a flue gas cycle control treatment part is arranged on the kiln body. According to the energy-saving environment-friendly lime kiln with flue gas recycle, waste heat of high-temperature flue gas exhausted from the kiln body is fully used and introduced into an air inlet of the kiln body, and air which enters the kiln body is subjected to heat transferand warming and is beneficial for increasing oxygen and supporting combustion so that the kiln temperature can be fast raised; moreover, the energy-saving environment-friendly lime kiln with flue gasrecycle has automatic feeding and ash discharging functions.

Description

technical field [0001] The invention relates to the technical field of energy-saving and environment-friendly lime kilns, in particular to an energy-saving and environment-friendly lime kiln for flue gas reuse. Background technique [0002] The lime kiln of the prior art comprises 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 unloading port, and the top of the furnace is provided with an annular flue outlet. The flue outlet communicates 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 object of th...
