In order to solve the problems of poor quality and serious pollution in the conventional tobacco flue-curing and realize the informationized management of tobacco flue-curing workshops, the invention discloses a natural gas heating circulating airflow tobacco flue-curing chamber. In the technical scheme, a combustion chamber is arranged outside the flue-curing chamber; a natural gas combustion furnace, an air heat exchanger and a temperature controller are arranged in the combustion chamber; a circulating fan is arranged at an air inlet between the flue-curing chamber and the combustion chamber; a smoke exhaust channel and a humidity-discharging opening are formed in the flue-curing chamber; a temperature sensor and a humidity sensor are arranged in the flue-curing chamber; and a tobacco frame is arranged in the flue-curing chamber. In the natural gas heating circulating airflow tobacco flue-curing chamber, central heating is performed by using natural gas, the temperature control accuracy of each flue-curing house is improved, the intensive flue-curing house is heated flexibly, discharges humidity smoothly and is convenient to operate; flue-cured tobaccos are full in color and luster and uniform in colors, the influence on the quality of the flue-cured tobaccos due to artificial error is avoided, the grade of the flue-cured quality of the tobaccos is improved, the natural gas serving as clean energy is used, and environmental pollution is reduced.

Description

Natural gas heat cycles air-flow tobacco flue-curing chamber
Technical field
The present invention relates to a kind of tobacco flue-curing chamber, specifically is a kind of natural gas heat cycles air-flow tobacco flue-curing chamber that utilizes, and belongs to the agricultural byproducts processing field.
Background technology
Ripe tobacco leaf will in time carry out dried after plucking results; Traditional drying tobacco processing method is at source to utilize coal stove to dry voluntarily by the tobacco grower; Because the tobacco grower grasps the difference of baking technology level, can make a big impact to the tobacco leaf product quality, is difficult to reach the higher quality grade.In recent years; China actively promotes in the area that tobacco planting is concentrated and utilizes bulk curing barn to concentrate baking; The index of correlation such as apparatus processing level, barn build guality, method for flue-curing tobacco leaves, baking quality of tobacco, baking energy consumption of bulk curing barn has all been had significantly improve, make the quality of tobacco grade obtain certain raising.But when building a large amount of bulk curing barns and curing barn cluster, some have also occurred and needed to be resolved hurrily and improved problem.At first be that environmental pollution is serious; Because the concentrated construction of barn; The little Combustion of Hot Air Furnace of existing in addition coal by hand is insufficient, gives off a large amount of black flue dust, when tens even a hundreds of baking oven chimney when discharging flue dust and flue gas simultaneously; Can form a large amount of black or yellow smog in flakes, directly have influence on peripheral villager's health; Badly influence the normal growth of crops; Next is a complex procedures in the tobacco flue-curing process, and recruitment is more, before baking, compiles the cigarette, makes a fire, adorns cigarette in the flue-cured tobacco process and smoke still takies a large amount of labours; Moreover tobacco leaf to dry by the fire used little hot-blast stove coal combustion insufficient, the thermal efficiency is low, so the coal resources consumption is very big, it is estimated, the annual tobacco flue-curing of China consumes coal up to 3,500,000 tons, serious waste of resources.
Summary of the invention
In order to overcome the problems referred to above that exist in the present tobacco flue-curing; Reduce greenhouse gas emission, reduce fossil fuel consumption, realize low-carbon (LC) tobacco flue-curing; The protection environment for human survival; Realize the information system management at tobacco flue-curing workshop, advance the development process of China's modern tobacco agriculture, the invention discloses a kind of natural gas heat cycles air-flow tobacco flue-curing chamber.
The present invention takes following technical scheme to implement to accomplish:
Concentrate the consistent baking vessel of several orderings is set; Outside each baking vessel, the combustion chamber is set, combustion furnace, air heat exchange machine, temperature controller are set in the combustion chamber, natural gas line is connected with combustion furnace, device natural gas valve between natural gas line and the combustion furnace; Have air inlet between baking vessel and the combustion chamber; Air inlet is provided with circulating fan, and baking vessel is provided with discharge flue and moisture exhausting port, unit temp inductor and humidity sensor in the baking vessel; The baking vessel both sides are respectively equipped with observation window and baking vessel's door, and what the tobacco leaf frame was orderly is positioned in the baking vessel.
The present invention is owing to adopt the natural gas central heating, and each bakery temperature control precision improves, and intensive bakery heats up flexibly; Hydrofuge is smooth and easy, is convenient to operation, and baking back tobacco leaf color and luster is full; The leaf color uniformity avoids the people to influence flue cured tobacco quality for fault, has improved the baking quality grade of tobacco leaf conscientiously; Use the clean energy resource natural gas, reduced environmental pollution.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing technical scheme of the present invention is explained further details:
Concentrate the consistent baking vessel (8) of several orderings is set; Combustion chamber (3) is set outside each baking vessel (8); Combustion furnace (4), air heat exchange machine (5), temperature controller (6) are set in the combustion chamber (3), and natural gas line (1) is connected with combustion furnace (4), device natural gas valve (2) between natural gas line (1) and the combustion furnace (4), has air inlet (9) between baking vessel (8) and combustion chamber (3); Air inlet (9) is 45 degree inclined-planes; Air inlet (9) is provided with circulating fan (7), and baking vessel (8) top is provided with discharge flue (15), the bottom is provided with moisture exhausting port (10), baking vessel's (8) interior unit temp inductors (11) and humidity sensor (12); Baking vessel (8) both sides are respectively equipped with observation window (14) and baking vessel's door (16), and tobacco leaf frame (13) is orderly is positioned over baking vessel (8).
To treat that flue-cured tobacco is placed on the tobacco leaf frame, close baking vessel's door, open the natural gas valve; The ignition combustion stove, the heat that combustion furnace produces arrives top of combustion chamber through the air heat exchange machine, and the heat that the air heat exchange machine distributes is recycled blower fan and sucks baking vessel; The hot-air that is admitted in the baking vessel forms circulating current; Pass the tobacco leaf on the continuous baking tobacco leaves frame in slit of the upper, middle and lower tobacco leaf at thermal current under the effect of circulating fan, arrive the bottom of cigarette-filling house then, get back to heating clamber through the hot air circulation passage again and carry out new heat cycles; Temperature inductor and humidity sensor are being monitored the temperature and humidity situation of change in the baking vessel at any time; When the baking indoor temperature is too high, through temperature inductor information is conducted into temperature controller, temperature controller is in time adjusted temperature according to the temperature that baking tobacco leaves sets; When the moisture of from tobacco leaf, discharging makes the baking indoor humidity too high; Humidity sensor is just controlled and is opened moisture exhausting port reduction baking indoor humidity, makes tobacco leaf remain at baking in the range of set temperature, when the flue gas overrich in the baking vessel, just opens discharge flue and gets rid of flue gas; Humidity in the maintenance baking vessel, humidity, flue gas concentration are all the time in the scope of setting, with the quality of tobacco after the assurance baking.
