Description
Technical field
The utility model relates to the technical field of flue-cured tobacco equipment, more specifically, relates to a kind of floor heating tobacco flue-curing house of gas fuel.
Background technology
Tobacco flue-curing house is indispensable basic equipment in cured tobacco production. Tobacco flue-curing house, after interior baking modulation, just shows the distinctive color of flue-cured tobacco, type, becomes the quality raw materials that meet cigarette industry needs. Its general principle is after tobacco leaf is heated, and the moisture in tobacco leaf is discharged, and is discharged from outside tobacco flue-curing house, thereby makes tobacco leaf scalding, dry after moisture vaporization.
Existing smoke hanging shelf can not be adjusted, and makes user inconvenient in hanging tobacco leaf and collecting the process of tobacco leaf. And in prior art, lack a kind of tobacco flue-curing house that utilizes heating installation.
Summary of the invention
The utility model is at least one defect overcoming described in above-mentioned prior art, and a kind of floor heating tobacco flue-curing house of gas fuel is provided, and it is simple in structure, easy to use, can effectively utilize floor heating device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of floor heating tobacco flue-curing house of gas fuel, wherein, comprise the flue-cured tobacco chamber that is provided with smoke hanging shelf, described smoke hanging shelf comprises the montant of vertical setting, the cross bar of horizontally set, and the quantity of described smoke hanging shelf is two and front and back setting on the length direction of flue-cured tobacco chamber; Described flue-cured tobacco chamber interior and flue-cured tobacco outdoor be extended with guide rail, smoke hanging shelf is located on guide rail;
Tobacco flue-curing house also comprises is located at ground floor heating device; Floor heating device is water floor heating device, and described floor heating device connects heater, and described heater is gas fuel heater.
In cold winter, indoor location floor heating device can be used for heating, can heating after floor heating device operation certain hour. In the utility model, utilize the heating installation distributing in floor heating device to toast tobacco leaf, utilize floor heating device and do not needed to arrange in addition heater, save the cost that heater is set in addition, floor heating device is located at the ground of tobacco flue-curing house, can not take the space of tobacco flue-curing house, save space, can effectively toast tobacco leaf.
Floor heating principle: floor heating is taking whole ground as radiator, by the heating agent in flooring radiation layer, the whole ground of homogeneous heating, utilize the accumulation of heat on ground self and heat upwards the rule of radiation conduct from the bottom to top, reach the object of heating.
Mainly be divided into Four types by floor heating: water floor heating, electric heating film floor heating, heating cable floor heating, the brilliant floor heating of carbon. The general principle of four kinds of floor heating modes is different.
In the present invention, utilize the heat distributing in floor heating device to carry out flue-cured tobacco, form the indoor temperature difference, finally carry out thermal cycle and make whole indoor temperature evenly increase. And utilize the form of water floor heating, while making flue-cured tobacco, maximum temperature reaches 60-70 degree left and right.
Further, described floor heating device comprises floor heating pipe, the roundabout formation geothermal system in the ground of floor heating pipe in tobacco flue-curing house.

In the present embodiment, the design of heating equipment and calculating
Maximum calorific requirement
The maximum dehydration stage of tobacco leaf, baking calorific requirement maximum. The dress cigarette amount mq that calculates barn according to barn cigarette-filling house volume and smoke filling density, tobacco leaf maximum water holding capacity is Wq, maximum dehydrating speed is Ws, maximum fluid loss Sp=mqwqws of unit interval; According to environmental condition, utilize h-d figure to find water capacity dk, the dp of air inlet cold air and moisture exhausting port hot-air, enthalpy hkc, hp, dry air amount Gkg=Sp/ (dp-dk)=mqwqws/ (dp-dk) that unit interval hydrofuge is required, maximum efficient heat (moisture evaporation maximum is taken away heat) Qz=GKg (hp-hkc)=(hp-hkc) mqwqws/ (dp-dk) of unit interval; Can extrapolate maximum calorific requirement Qgr=Qz/ η=(hp-hkc) mqwqws/ (dp-dk) η by the thermal efficiency η of barnFormula (1)。
Heat exchange area
The size of heat exchange area is relevant with the thermal conductivity factor of the maximum calorific requirement of barn and heat exchanger materials, and heat exchanger area of dissipation (Ag) is the ratio of maximum calorific requirement and radiating tube heat transfer coefficient (Kgt) and cigarette inner tube smoke mean temperature (tej) product: Ag=Qgr/ (Kgt.tej)Formula (2)。
Maximum consumption fuel quantity
Try to achieve according to design hothouse baking ability after the maximum calorific requirement (being the maximum heating load of burner) of unit interval, can calculate barn unit interval maximum consumption fuel quantity (Gpm).
Gpm=Qgr/Qnet.ar⑶, in formula, Qgr is maximum calorific requirement KJ/h of barn unit interval, the calorific capacity KJ/Kg that Qnet.ar is fuel.
Bulk curing barn tobacco leaf calorific requirement is calculated:
Maximum calorific requirement
Bulk curing barn cigarette-filling house specification is 800cm × 270cm × 350cm, and cigarette-filling house's volume is 75.6m3: smoke filling density is 59.52～66.14 ㎏/m3, for calculating the maximum heating load of barn, get its maximum 66.14 ㎏/m here3; Amassing of the Zhuan Yanliangwei cigarette-filling house volume of bulk curing barn and smoke filling density: 75.6m3×66.14㎏/m3=5000kg
The water content of fresh tobacco leaf is generally 80-90%, gets maximum W hereq=90%; Moisture content in leaves vaporization speed capping W when large hydrofuges=2.5%; The water capacity capping d of the waste gas that moisture exhausting port is dischargedp=0.046kg/kg dry air; The water capacity that air intake hole enters the cold air of barn removes the limit dk=0.021kg/kg dry air; By looking into h-d figure, known discharge hot-air and the enthalpy that enters cold air, hp=134.4kJ/kg, hkc=79.8kJ/kg: general 40% left and right of the thermal efficiency of bulk curing barn. Bring above each value into formula (1), can calculate the maximum calorific requirement of bulk curing barn: Qgr=609749.45kJ/h.
In the present embodiment, using natural gas as fuel,
The fuel value of natural gas is about 8.4 × 10^7 Jiao/cubic meter,
1 liter=0.001 cubic metre,
One liter of natural gas produces heat,
Q=8.4 × 10^7*0.001=8.4 × 10^4 joule,
Natural gas density is 420-460Kg/ cubic meter,
The calory burning that is natural gas is: 182.6-200kJ/Kg
Can be regarded as to such an extent that unit interval consumption natural gas is 3048.75-3339.26Kg/h by formula (3) Gpm=Qgr/Qnet.ar. In the present embodiment, in tobacco flue-curing house, need the new fresh tobacco leaf of general 15000 jin to be roasted into the tobacco leaf of 1500 jin.
Tobacco flue-curing, by average 6 days of three positions of upper, middle and lower, is discharged 90% moisture content in leaves, and to need amount of natural gas be (3048.75-3339.26Kg/h)/(48h × 0.6 × 0.9)=117.62-128.83Kg to the dry cigarette of per kilogram.
Therefore, the dry cigarette of per kilogram needs natural gas probably for 117.62-128.83Kg.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model. For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description. Here without also giving exhaustive to all embodiments. All any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of the utility model claim.
