Energy-saving environment-friendly lime kiln furnace capable of recycling flue gas waste heat

Abstract

The invention discloses an energy-saving environment-friendly lime kiln furnace capable of recycling flue gas waste heat, which includes a base plate. One side of the top of the base plate is fixedlyconnected with a purifying box. The top of the purifying box is fixedly connected with a transmission box. The top of the transmission box is fixedly connected with a waste heat recovery box. Both sides of the back surface of the inner wall of the waste heat recovery box are rotatably connected with a first hollow rotating shaft through a bearing. Both sides of the front surface of the inner wallof the waste heat recovery box are rotatably connected with a second hollow rotating shaft through a bearing. The lime kiln furnace relates to the technical field of the lime kiln furnaces. The energy-saving environment-friendly lime kiln furnace capable of recycling flue gas waste heat greatly enhances the waste heat recovery effect, perfectly enlarges the application range of waste heat of recovery, realizes two methods of waste heat recovery, gas-liquid heat conduction and gas-gas heat conduction, for flue gas produced by lime kiln furnaces, accomplishes the purpose of thoroughly recyclingthe waste heat produced by flue gas and enhancing the utilization range of the waste heat , so that the purpose of energy conservation and environmental protection for the use of the lime kiln furnaceis well achieved.

Description

technical field [0001] The invention relates to the technical field of lime kilns, in particular to an energy-saving and environment-friendly lime kiln for recycling flue gas waste heat. Background technique [0002] Flue gas is the main way for general energy-consuming equipment to waste energy. For example, the energy consumption of boiler smoke exhaust is about 15%, while other equipment such as setting machines, dryers and kilns in the printing and dyeing industry mainly consume energy through flue gas discharge. The waste heat recovery of the flue gas is mainly to convert the heat carried by the flue gas into usable heat through a certain heat exchange method. The lime kiln in the prior art includes a furnace body with an insulating layer, a furnace body, and a furnace body The top of the furnace is equipped 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, which i...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an energy-saving and environment-friendly lime kiln for waste heat recovery of flue gas, which solves the problem that the existing waste heat recovery effect is poor, and the application range of the recovered waste heat is relatively narrow, and the lime kiln cannot be realized. The waste heat in the flue gas is generated by two waste heat recovery methods of gas-liquid heat conduction and gas-gas heat conduction at the same time, which cannot achieve the purpose of completely recovering the waste heat in the flue gas and enhancing the use range of the recovered waste heat
