The invention discloses a novel rotary kiln utilizing waste heat to cyclically support combustion. The novel rotary kiln comprises a plurality of material pushing chambers, a plurality of rotary cellars, a circulating fan, a plurality of smoke collection chambers and a smoke exhauster, feeding ports are formed in the tops of the material pushing chambers, outlets of the material pushing chambers are connected to inlets of combustion chambers, outlets of the combustion chambers are connected to inlets of the rotary cellars, outlets of the rotary cellars are connected to an inlet of a dust collector, the dust collector is connected to a carbon dioxide absorption device through the circulating fan, the inlet ends of the rotary cellars are connected to inlets of the smoke collection chambers through air chambers, and outlets of the smoke collection chambers are connected to the smoke exhauster through dust collection chambers. According to the novel rotary kiln, raw materials are processed by adopting smoke generated by combustion, the combustion temperature is increased, and therefore resources are fully utilized, energy conservation and emission reduction are realized, the structure is simple, operation is convenient, the heat transfer effect is good, and the working efficiency can be effectively improved through the double-end combustion design.
Description
technical field [0001] The invention relates to a novel rotary kiln which utilizes waste heat circulation to support combustion. Background technique [0002] Industrial kilns are thermal equipment that use heat from fuel combustion or electrical energy conversion to heat materials or workpieces in industrial production. Rotary kiln is a new type of furnace widely used in industrial furnaces. It has the advantages of uniform heating, high thermal efficiency, continuous production, and good calcining quality of products. It is widely used in metallurgy, chemical industry, building refractory materials, environmental protection and other industries. [0003] The existing semi-coke production technology is that raw coal is dry-distilled at low temperature in a vertical semi-coke furnace. The semi-coke tail gas is not fully utilized, which affects the cost of semi-coke and pollutes the atmospheric environment. The use of rotary kiln dry distillation is a new technology for semi...
