Abstract

The invention discloses an energy-saving environment-friendly lime kiln for smoke gas afterheat reuse. The energy-saving environment-friendly lime kiln comprises a furnace body provided with a heat insulation layer, wherein a hearth is arranged in the furnace body; an automatic feeding opening is formed in the top of the hearth; the lower end of the hearth is provided with an automatic ash discharging opening; an annular smoke discharging passage is formed in the top of the hearth. The energy-saving environment-friendly lime kiln is characterized in that the smoke discharging passage is communicated with a desulfurization dust remover through a heat exchanger via a fan; an air inlet and outlet opening is formed in the heat exchanger and is communicated with an air inlet formed in the lowerpart of the hearth through the fan. The air entering the hearth is subjected to heat exchange temperature rise; the oxygenation combustion support is facilitated; the furnace temperature can be fastimproved; the energy saving effect is obvious; the technical problem that the afterheat of the high-temperature smoke gas discharged from the smoke discharging passage is not sufficiently utilized inthe prior art 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 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.
