A large-capacity energy-saving and environment-friendly dense barn

Abstract

The invention provides a large-capacity energy-saving environment-friendly bulk curing barn which comprises a curing chamber and a heating chamber. The curing chamber is provided moisture discharge openings, and a heating device is arranged in the heating chamber. The large-capacity energy-saving environment-friendly bulk curing barn is characterized in that the heating device is composed of a steam boiler and a plurality of steam heat radiators, the steam boiler is arranged outside the curing barn, the steam heat radiators are arranged in the heating chamber and the curing chamber in a disperse mode, the steam inlet ends of the steam heat radiators are respectively communicated with a steam outlet of the steam boiler through steam pipelines, water return openings of the heat radiators are respectively communicated with a water inlet of the steam boiler through water return pipes, and a fan is arranged on a heat radiating opening of each steam heat radiator. Tobacco inlet rails are arranged on the ground of the curing chamber. The moisture discharge openings are formed in the positions, as high as a cold air door, of the lower portions of the two side walls of the curing chamber respectively. According to the large-capacity energy-saving environment-friendly bulk curing barn, the construction cost of the curing barn is greatly lowered, meanwhile, the cost of a coal stove, the fans and other curing equipment is saved, labor force for curing is reduced, and the labor intensity of tobacco curing is lowered.

Description

technical field [0001] The invention belongs to the field of flue-cured tobacco, and in particular relates to a large-capacity, energy-saving and environment-friendly intensive barn, which can effectively use space, save energy and reduce emissions, and reduce labor and cost. Background technique [0002] The curing barn is a necessary equipment in the tobacco leaf curing process, and it is very important to the quality of the tobacco leaves obtained by baking. The quality of the cured tobacco leaves has been greatly improved by the promotion of dense barns in my country, but with the continuous development of flue-cured tobacco production, The limitations of the existing barns are becoming more and more prominent, mainly as follows: ①The capacity of the barns is small, which is not suitable for the large-scale, industrialized and professional development of flue-cured tobacco; It is difficult for large households to plant flue-cured tobacco on farms and farms (large household...

Problems solved by technology

[0002] The curing barn is a necessary equipment in the tobacco leaf curing process, and it is very important to the quality of the tobacco leaves obtained by baking. The quality of the cured tobacco leaves has been greatly improved by the promotion of dense barns in my country, but with the continuous development of flue-cured tobacco production, The limitations of the existing barns are becoming more and more prominent, mainly as follows: ①The capacity of the barns is small, which is not suitable for the large-scale, industrialized and professional development of flue-cured tobacco; It is difficult for large households to plant flue-cured tobacco on farms and farms (large households generally plant flue-cured tobacco on 100-500 mu, and farm cultivation generally exceeds 500 mu). If the existing dense curing barn is still used to prepare tobacco leaves, large households need 5-25 1 barn, farm planting requires 40 barns, and 1 person in the roasting operation can manage 3-5 barns at most. The work efficiency is low, the management is difficult, the labor cost is high, the baking technology is not uniform, and the roasting quality is low. There is no guarantee, which restricts the development of scale, industrialization and specialization of flue-cured tobacco planting

②The heating equipment of the existing dense barn is to place the heating furnace directly in the heating room, and the heating is carried out by the combustion hot gas of the heating furnace. The heat utilization rate is low and the dust pollution is serious. Since the heating equipment is placed in the barn, it will A large amount of dust has accumulated. After 1-2 years of use, due to the difficulty in cleaning up the accumulated dust or improper management of the equipment, the heat transfer efficiency of the heating system is reduced, the utilization rate of heat energy is not high, and fuel waste is caused; at the same time, the heating equipment is not tightly sealed. The soot leaks out and enters the barn, causing pollution to the cured tobacco leaves
