Waste heat sharing intensive tobacco flue-curing house and operating method thereof

Abstract

The invention relates to a waste heat sharing intensive tobacco flue-curing house, which is formed by connecting a plurality of tobacco flue-curing rooms into a whole. Adjacent tobacco flue-curing rooms are spaced through longitudinal common partition walls; the back end of each tobacco flue-curing room is provided with a heating chamber which corresponds to the tobacco flue-curing room; the tobacco flue-curing room and the heating chamber are spaced through a transverse common partition wall; a humidity reducing passage and a waste heat sharing passage which hermetically communicates the tobacco flue-curing rooms are arranged in each tobacco flue-curing room; and the waste heat sharing passage consists of a waste heat heating passage and a waste heat dampening passage which are firmly spaced through a waste heat sharing passage partition wall and are communicated with the humidity reducing passage respectively. The waste heat sharing connected intensive tobacco flue-curing house has the advantages of simplifying and improving the building structure of the flue-curing house, lowering construction cost, saving energy and reducing consumption, lowering curing cost and curing labor, and enhancing heat cyclic utilization ratio and stably enhancing the quality of the flue-cured tobacco, along with scientific structure, reasonable layout, convenient operation, and high performance.

Description

technical field [0001] The invention relates to a waste heat sharing conjoined intensive curing room and an operation and use method thereof, in particular to a waste heat sharing intensive tobacco curing room specially used for tobacco leaf curing and an operation and use method thereof. Background technique [0002] At present, domestic and foreign coal-fired ovens are more accurate in controlling humidity in baking automatic control, but the temperature control effect is not good, which affects the quality stability of flue-cured tobacco; in the baking process and baking operation, whether it is a group of baking rooms It is still a single roasting room. The high-temperature heat formed during the drying period of roasting and a large amount of wet hot water steam formed during the drying period are all in the form of direct discharge, which is directly discharged to the outside of the flue-cured tobacco, and the heat energy cannot be recycled, resulting in energy waste. ...

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
