Low-carbon dense baking system for modulating cured tobacco

Abstract

The invention relates to a low-carbon dense baking system for modulating cured tobacco, comprising a group of dense curing barns; a double-arch film tent is arranged above each dense curing barn; a double-arch film heat-collecting and heat-trapping room is arranged below each double-arch film tent; the double-arch film heat-collecting and heat-trapping room is communicated with a hot air shared passage; a single-pit hot air personal passage communicated with a dense curing barn heating room is arranged on the hot air shared passage; a high-temperature smoke radiation pipe communicated with a heating furnace chimney through a smoke on-off machine is arranged in the double-arch film heat-collecting and heat-trapping room; the high-temperature smoke radiation pipe is communicated with a smoke interconnecting passage; and the smoke interconnecting passage is communicated with a smoke devulcanizer; and the smoke devulcanizer is communicated with a desulphurization reaction settling pond. The system is reasonable in design, thereby reducing the energy consumption of the tobacco modulation by more than 40% and reducing the discharge of pollutants by more than 60%.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing roasting system for a barn, in particular to a low-carbon intensive roasting system suitable for flue-cured tobacco modulation in dense barns. Background technique [0002] At present, when tobacco leaves are baked, the conventional heating energy is mainly coal. Although the tobacco leaf-intensive curing barns currently promoted have a certain coal-saving effect compared with traditional barns, there are still extensive methods, large resource consumption, serious waste, Intensified pollution and other issues; there are also some dense barns that have added solar thermal applications on the top of the barn, but the limited top area of ​​a single barn limits the collection of heat energy, and the limited heat energy collected is limited to the barn. However, the waste heat sharing technology is complicated in the structure of waste heat sharing, and the construction cost is high or the str...

Problems solved by technology

[0002] At present, when tobacco leaves are baked, the conventional heating energy is mainly coal. Although the tobacco leaf-intensive curing barns currently promoted have a certain coal-saving effect compared with traditional barns, there are still extensive methods, large resource consumption, serious waste, Intensified pollution and other issues; there are also some dense barns that have added solar thermal applications on the top of the barn, but the limited top area of ​​a single barn limits the collection of heat energy, and the limited heat energy collected is limited to the barn. However, the waste heat sharing technology is complicated in the structure of waste heat sharing, and the construction cost is high or the structure is simple and the application effect is not good, which limits the practical application; so far, all The tobacco leaf-intensive curing barns that use coal as the heating energy do not treat the coal combustion emissions and discharge them directly into the atmosphere during use, which has serious pollution problems; It is an inevitable choice for the development of modern tobacco agriculture and the improvement of tobacco leaf curing technology, and it will also effectively drive the energy saving and emission reduction work of large-scale agriculture. Promote the transformation of agricultural production mode
