Description

Interior circulating dehumidification bulk curing barn based on air energy

Technical field

The utility model belongs to tobacco leaf baking system, especially a kind of to be used using the tobacco flue-curing of internal air circulation and dehumidifying Bulk curing barn.

Background technique

Barn is the essential professional equipment of tobacco flue-curing operation.With the constant growth of productivity, China's barn from The open fire barn of earliest period, the development of natural ventilation type traditional flue-curing barn are heated air circulation type barn, general change close barn.20 end of the centurys Phase, with China's science and technology and economic progress and the large-scale production of flue-cured tobacco, it is raw that bulk curing barn has gradually adapted to China's flue-cured tobacco The new situations for producing sustainable development, represent the developing direction of current flue-cured tobacco equipment.The working principle of bulk curing barn baking system is Forced ventilation is carried out as thrust using blower and hot air circulation mode heats the tobacco leaf in cigarette-filling house, promotes object inside tobacco leaf Matter conversion, synthesis, dehydration, drying are regulated and controled the degradation of substance in tobacco leaf by temperature and humidity controller and wind-speed adjusting device, closed At, conversion rate and tobacco leaf appearance coloration.Although bulk curing barn is in terms of dress smoke, baking quality of tobacco, intensive degree Embody huge advantage.But still there are some problem needs to probe into and solve in application process, though it is on the one hand economic benefit Promoted compared with traditional baking chamber, but cost is still higher, be mainly reflected in manual operation excessively cause cost of labor excessively high and Forced-ventilated is wet to cause amount of heat to lose, and causes that energy loss is big, energy consumption cost is high；It on the other hand is baking automatic control equipment and technology Not mature enough, it is not perfect or unreasonable to be mainly reflected in hardware facility, using fuel such as coal and petroleum as supplying heat source, causes to dry The poor controllability of temperature in roasted journey, the present Research for being limited by hardware facility also indirectly affect the development of software aspects, Cause software design too simple, control precision is low, increases manual operation load.This requires the development of China's bulk curing barn to build Material selection, hardware device transformation, automatic control very well equipped etc. is made to be badly in need of incorporating new blood.

Tobacco flue-curing required time is generally 6 ~ 10 days, therefore must have enough heats to supply in baking process. External tobacco flue-curing is using diesel oil, natural gas as fuel.And China is limited by the influence of economic development, the fuel that foreign countries use It is not appropriate for China's national situation, China's tobacco flue-curing is mostly using coal, biomass as fuel, although biomass fuel source is wide and can Regeneration, but cost is higher compared to coal, machine used in the natural ventilation airflow ascending manner barn to current toast from early stage Tool divulges information thermal cycle barn generally using coal as main fuel.Since baking system equipment and baking technology backwardness lead to coal energy Consumption is high, and every kilogram of dry tobacco leaf coal consumption is generally 1.5 ~ 2.0 kg, and utilization efficiency only has 30% or so, and release of burning A large amount of harmful substance will cause serious pollution to environment, studies have shown that carrying out tobacco flue-curing, every kilogram of tobacco leaf using coal It will lead to coal and generate NO_x 0.0094kg、SO₂0.0132 kg and CO₂4.302kg.With the whole world for demand for fuel not Disconnected to increase, cost used in tobacco flue-curing constantly rises.

Either curing barn cluster or monomer barn in the barn that current tobacco flue-curing operation uses, fixation hydrofuge phase flue-cured tobacco room In damp and hot steam and the indoor high temperature air of drying muscle stage flue-cured tobacco be discharged outside flue-cured tobacco room in the form of in line, cause the energy compared with Big waste.It is found by researches that the heat lost is about the 10% ~ 20% of total energy consumption, and highest is even during forced-ventilated is wet Reach 25%, moreover, the cigarette perfume that tobacco leaf comes out also has been exhausted during the hydrofuge of tobacco flue-curing.In control technology It is surely warm in baking process although existing bulk curing barn realizes semi-automation and automates substantially on baking process Duration, heating rate, hydrofuge opportunity, coal opportunity, coal amount etc. still also rely on artificial experience and go to control, and due to existing The overall structure and baking process of bulk curing barn baking system are all built upon on the wet dehumidification mode of coal heating, forced-ventilated, Again because the hysteresis quality and uncontrollability of coal-fired heating make researcher insufficient for the research of control aspect, compares and have progressed Property research also only achieving some achievements in terms of automatic stoking, automatic hydrofuge, and in intelligent control, intelligence baking, collection Groupization baking aspect is still relatively backward.
