Waste heat-sharing integral-body compact flue-curing barn and operating-using method thereof

Abstract

The invention relates to a waste heat-sharing integral-body compact flue-curing barn, which consists of a plurality of tobacco-curing chambers connected as a whole, wherein the adjacent tobacco-curing chambers are spaced through a longitudinally arranged public partition wall; the back ends of the tobacco-curing chambers are provided with heating chambers corresponding to the tobacco-curing chambers; the tobacco-curing chambers and the heating chambers are spaced through a transverse public partition wall; the inside of the tobacco-curing chambers is provided with moisture-removing channels, as well as waste-heat heating channels and waste-heat dampening channels hermetically communicating all the tobacco-curing chambers; the waste-heat heating channels and the waste-heat dampening channels are in H-shaped communication with the moisture-removing channels respectively; the moisture-removing channels lead to outside; the tobacco-curing chambers are provided with moisture removal air inlets inside; and the front ends of the tobacco-curing chambers are provided with tobacco loading / unloading doors, tobacco change observation windows and reduced-pressure heat-exchange air outlets. The waste heat-sharing integral-body compact flue-curing barn has the advantages of scientific structure, reasonable layout, convenient operation, good performance and capability of simplifying and improving architectural structure of the flue-curing barn, reducing construction cost, saving energy, reducing consumption, reducing curing cost and labor, improving the utilization rate of heat energy circulation and stably improving the quality of flue-cured tobacco.

Description

technical field [0001] The invention relates to a waste heat sharing conjoined dense barn and its operating method, in particular to a waste heat sharing conjoined dense barn specially used for tobacco leaf curing and its operating method. Background technique [0002] At present, coal-fired barns at home and abroad have relatively accurate humidity control in terms of baking self-control, but the temperature control effect is not good, which affects the stability of flue-cured tobacco quality; It is still a single barn. The high-temperature hot air formed during the drying and drying period and the large amount of wet and hot water vapor formed during the dehumidification period are all discharged directly to the outside of the flue-cured tobacco. The heat energy cannot be recycled, resulting in energy waste. [0003] With the continuous development of the large-scale planting level of flue-cured tobacco production in my country, intensive curing rooms have become the main ...

AI Technical Summary

Problems solved by technology

Large-scale step-by-step continuous curing barns have been studied in the southern tobacco areas of my country, and continuous curing has been realized. However, there are still many insurmountable problems in the actual test, including the low density of smoke in the barns and the large area occupied by the tobacco leaves. The contradiction of insufficient roasting energy during concentrated ripening, the large temperature gradient before and after the smoke chamber, the large temperature difference between the upper and lower layers, the harsh working environment and high labor intensity of the roasting operation, and the residual heat discharged cannot be recycled, resulting in energy waste
