Abstract
The utility model relates to a heat radiating pipe for a tobacco flue-curing house. A tobacco inlet is positioned above the back end of a furnace chamber of a combustion chamber; the front end of a main dragon is connected with the tobacco inlet, and the back end of the main dragon is bifurcated and is respectively connected with two annular fire pipes which are positioned on the left side and the right side of the main dragon; the two fire pipes are slantways arranged from top to bottom in a surrounding mode; the outlet end of the two fire pipes gathers below the front end of the main dragon, and the outlet end of the two fire pipes is lower than the height of a tobacco outlet of the furnace chamber 40CM to 120CM; both the lower left side of the main dragon and the lower right side of the main dragon are respectively provided with ventilation pipes; an air inlet is communicated with the outside of a baking house, and the left flank and the right flank of the air inlet are provided with air outlets. The heat radiating pipe for tobacco flue-curing house lengthens the process of hot air inside a tobacco flue-curing house, enhances the utilization rate of the hot air, enlarges heat radiating areas and enlarges the heating surface of tobacco to cause the energy consumption of the tobacco flue-curing house to be reduced to achieve the purpose of saving fuel; air blowed in by the two ventilation pipes can accelerate the water exhaustion of cyan tobacco leaves to speed up a flue-curing progress to cause the time consumption of tobacco flue-curing to be shortened.
Description
Technical field
The utility model belongs to a kind of tobacco flue-curing house hot channel, is specially adapted in the production of cigarettes baking to blue or green tobacco leaf.
Background technology
Tobacco flue-curing house is the equipment of baking tobacco leaf in the production of cigarettes, mainly is made up of barn, heating plant and air duct.Heating plant is made up of combustion furnace, hot gas hot channel and chimney, and the front opening place of hot gas hot channel connects the exhaust opening of combustion chamber, and other end opening part connects chimney, and chimney stretches out outside the barn; Wherein, the hot gas hot channel is called main dragon from the major trunk roads of one section craspedodrome that burner hearth sends, and the branch beyond the main dragon is called fire tube.The simplest tobacco flue-curing house is an imperial fire, and promptly a main dragon, a fire tube because hot-air flowing time in pipe is shorter, so the exchange heat time is short, poor effect, exist baking efficient not high, the shortcoming that thermal loss is more.Along with the development of baking of flue-cured tobacco technology, the design of tobacco flue-curing house changes to some extent, two troubles about the rear end of main dragon is divided into, and each turnout is a fire tube.The heat utilization ratio of this barn increases, but the efficient of Btu utilization is still not fully up to expectations, has the more problem of consumption coal.
The utility model content
Goal of the invention of the present utility model provides a kind of fire tube lower step mode energy saving flue-cured tobacco-room hot channel, and its technical scheme is as follows:
A kind of hot channel of tobacco flue-curing house is installed on tobacco flue-curing house inside, mainly constitutes by advancing mouth, main dragon, several parts of chimney, enter the top, rear end that mouth is positioned at combustion chamber, this advances mouth the preceding termination of main dragon, and the rear end fork connects two fire tubes in the form of a ring that are positioned at the main imperial left and right sides respectively; Article two, fire tube from top to bottom the inclined ring winding put, its port of export meets at main imperial front end below, outlet is connected on stretches out the outer chimney lower end of barn.
Main imperial rear end is higher than the burner hearth outlet flue, and two exit positions that fire tube crosses are lower than the height of burner hearth outlet flue.
The left and right sides has a ventilation duct respectively below main dragon; Ventilation duct is positioned at barn inside, and its air inlet is communicated with outside the barn, all has air outlet on two sides about it.
This structure is owing to adopt the middle part that main dragon is set, and both sides are provided with a ring-type fire tube respectively, and the flow process of hot-air at tobacco flue-curing house not only extended, improved the hot-air utilization rate, and enlarged heat radiation surface, make tobacco flue-curing house middle part and can both being heated to have enlarged the heating surface of tobacco all around.
Be positioned at the burner hearth below because fire tube is tilted to down the outlet of layout fire tube simultaneously, the holdup time of hot-air in barn increased, thereby increased the heat radiation time, greatly improved the utilization rate of heat, the power consumption of tobacco flue-curing house is reduced, reach fuel-saving purpose.
By the principle that hot-air rises, cold air descends, barn outer air temperature is lower than air in the barn, so the outer air of barn can enter in the barn along the ventilation duct under the main dragon.Article two, the air that blows out in the air vent of the side that ventilation duct is relative crashes, and upwards blows on main dragon, reduces the high temperature on the main dragon, and the temperature difference in the balance barn strengthens the radiating effect of main dragon simultaneously; Article two, the air that blows out in the air vent in the ventilation duct outside can make the hot-air of barn inside form convection current, temperature in the balance barn, and the moisture of accelerating in the blue or green tobacco leaf is discharged, and quickens the baking process, makes the shortening consuming time of flue-cured tobacco.
Description of drawings
Fig. 1 is a schematic perspective view of the present utility model.
