Description
Technical field
The present invention relates to tobacco leaf processing technique field, be specifically related to a kind of baking equipment for preparatory treatment of tobacco.
Background technology
Before phase early 1970s, tobacco curing barn is natural ventilation airflow ascending manner barn, modulation capability about 2 ~ 3 mu, its heating system is the dragon type fire tube of the brick or ceramic be positioned at bottom barn, logical chimney after front even combustion furnace, the high-temperature gas that fuel combustion produces is through being laid on the ceramic fire tube net bottom barn, discharged by chimney, airflow circulating system only has hole in the ground and skylight, cold air enters from hole in the ground, the air be heated natural flow from bottom to top, flow through the combustion furnace and fire tube surface that are heated, carry heat to continue to rise to heat the temperature in tobacco leaf and stable barn, open skylight, hot-air nature flows out from skylight, realize hydrofuge and air circulation.The basic characteristics of natural ventilation airflow ascending manner barn are: the air motion in barn meets aerodynamics general principle, and in barn, hot-air rises naturally, and barn bottom natural forms negative pressure, provides natural power for outdoor cold air enters barn from hole in the ground; Namely outdoor cold air is met fire tube and is heated after refrigerated wind tunnel enters barn, naturally to expand after being heated rising, even heat is taken to each aspect of barn, being heated and moving of this air is horizontal planar, the stable state of each spot temperature humidity and wind of barn and dynamic all relative equilibriums, modulated process intensification hydrofuge is balanced.
The eighties in 20th century, promote the small-sized barn about capacity 150 pole, modulation capability is about 3-5 mu.Skylight changes bar shaped into by square, and refrigerated wind tunnel changes hot air wind tunnel into, makes barn hydrofuge more smooth and easy, effectively alleviates the problems such as the steaming sheet occurred in tobacco leaf modulated process, poor sheet and dust.
Early 1990s, Province Smoke Science Institute, Guizhou have developed air-flow down type roasting room, and its feature had is as follows: one is, ground does not have fire tube in cigarette-filling house, dress cigarette, unloads that cigarette is more convenient, safety; Two are, in cigarette-filling house, humiture is less by the impact of environmental condition, has part hot air circulate; Three are, the barn levels temperature difference is comparatively large, and hydrofuge effect is bad.
About 2000, bulk curing barn started application, and the control principle of bulk curing barn is by the chip of tobacco leaf modulation process curve write micro computer, and the controller that chip is housed controls corresponding mechanism automatically according to the technological parameter arranged.Its technological parameter is is main shaft with concept of time, take temperature and humidity as controlling value, its controlling functions mechanism major way is: the heat supply strength control realizing fire coal by regulating the oxygen supply blower fan of airtight combustion chamber, and then realizes the control to heating up; By the control realization hot air circulation to circulating fan; By controlling the open degree of cold-air flap to realize hydrofuge.Bulk curing barn has the advantage that fixation is easy, modulation period shortens, the uniformity of tobacco leaf presentation quality is high, but also there is following shortcoming: one is, consume energy high, pollute large, specifically: intensive baking room consumes coal 350-450 ten thousand tons every year, the coal fire discharged amount of annual flue-cured tobacco is CO
2about 8,380,000 tons, SO
2about 2.56 ten thousand tons, NO
xabout 2.368 ten thousand tons, SO
2, NO
x, carbon black, flying dust, the pollutant such as dust cause significant damage to environment and people ' s health; Two are, quality of tobacco is poor, and specifically: based on the theory of " fast yellow quick-drying ", cause blade stiffness to increase the weight of, color is desalinated, and oil content reduces, and fragrance weakens.
In sum, be badly in need of a kind ofly significantly can promoting tobacco leaf modulation quality in industry, promote tabacco fragrance and there is again the baking equipment for preparatory treatment of tobacco of environmental protection and energy saving feature to solve problems of the prior art.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can limit according to claim and cover is implemented.
Embodiment 1:
See Fig. 1-Fig. 7, a kind of baking equipment for preparatory treatment of tobacco, design wind supply quantity is 18000m
3/ h, between design leaf, wind speed is 0.1-0.2m/s, specifically comprises heater, humidity-discharging device, feeding device, controller and barn 5.
Described heater comprises biomass combustion furnace 1.1, the heat exchanger 1.2 be connected with the smoke outlet tube of described biomass combustion furnace 1.1 and the circulating fan 1.3 for carrying hot blast or cold wind, and Details as Follows:
The structure of described biomass combustion furnace 1.1 refers to Fig. 1, Fig. 2, Fig. 3 and Fig. 5, specifically comprise combustion furnace body 1.12, supply air system 1.13 and control system three parts, described combustion furnace body 1.12 is small boilers, adopt rigid grate, comprise shell a, the combustion chamber b be arranged in shell a, aerator and lighting-up tuyere e, the similar coal-burning boiler of furnace chamber volume of combustion chamber b increases a lot (volume approximately increases 3-5 doubly), with the feature of adapted biomass fuel height volatilization; Described supply air system 1.13 comprises the blower fan c be arranged in described combustion furnace body 1.12, it adopts secondary blast structure, specifically: the air of once blowing enter from b lower end, combustion chamber between its outer wall and shell a every dead level d, wherein portion of air enters in the b of combustion chamber through fire grate, form the air-flow moved upward, make fuel particle suspension fluidization, strengthen air and fuel mix degree, prolonging burning time, makes sufficient combustion; The lighting-up tuyere e end of other portion of air through entering combustion chamber b every dead level d mixes with flue gas, reduce flue-gas temperature, increase exhaust gas volumn and speed, flue gas is made to accelerate outwards spray, simultaneously, the air of secondary blast enters combustion chamber b in middle-end and fuel mix, and main mixing with the volatile ingredient of fuel burns.Twice air-supply makes fuel particle carry out suspension combustion in furnace chamber.And the exhaust of described biomass combustion furnace 1.1 adopts ejector principle to carry out.Air is blown by blower fan, enters bellows, and pro-rata enters in combustion furnace, and reasonable wind distribution is the primary condition of burned living beings, and because volatile matter is high and separate out rapidly, carrying out the disturbance of burner hearth flue gas by Secondary Air is the effective measure that volatile matter is burnt completely; General Secondary Air accounts for 25 ﹪ ~ 30 ﹪ of total blast volume; Following current mixed form at the mixed form of bocca end air and flue gas.Auxiliary auxiliary combustion equipment 3 is negative pressure combustion fan, and it is connected with described biomass combustion furnace 1.1.The bottom of described biomass combustion furnace 1.1 is provided with two groups or four groups of scroll wheels 1.11, is convenient to carrying.
