A kind of biological particles for bulk curing barn and heat pump united heat supply method
Technical field
The present invention relates to a kind of biological particles for bulk curing barn and heat pump united heat supply method, belong to tobacco flue-cured tobacco Technical field.
Background technology
Flue-cured tobacco is the Important Economic crop of economically underdeveloped area of China, and in production process of flue-cured tobacco, flue-cured tobacco modulation is one Individual key link, the quality of modulating equipment, the modulation quality and tobacco grower for directly affecting flue-cured tobacco are taken in.It is with the development of science and technology, roasting Cigarette modulating equipment develops into hot air circulating baking chamber from common earth roasting house, intensive intelligent barn till now.Current intensive intelligence The main heat-supplying mode of barn is coal-fired, and some is using electric energy (air source heat pump, far infrared, electromagnetism), biomass, alcohol radical The bulk curing barn of the renewable clear energy sources heat supply such as fuel.But carbon dioxide, the sulfur dioxide of coal-fired bulk curing barn discharge at present Dust particle, environment is had undesirable effect;And with the clean energy resource heat supply such as solar energy, electric energy, alcohol-based fuel, biomass energy Bulk curing barn, have that input cost is high, needs the problems such as electrical power is high, cost of material is high to be widely applied.
Heat pump techniques are a kind of environmentally friendly skills that can effectively save the energy, reduction CO2 emissions and reduction atmosphere pollution Art.Low-temperature waste heat (such as bulk curing barn dehumidifying waste heat) in nature can be transformed into available regenerated heat energy by heat pump, will Heat pump techniques are applied to tobacco flue-curing, be one can save fossil fuel, reduce greenhouse gas emission, improve energy utilization rate enter And mitigate the new way of environmental pollution.But heat supply is carried out to bulk curing barn using heat pump, required power about 12KW, one is transformed and bakes About 5.5 ten thousand yuan of expense needed for room heat pump bulk curing barn, largely transformation such as is carried out in barn factory, it is necessary to upgrade to supply line, Dilatation is carried out to transformer, and need to additionally configure stand-by power supply, disposable input is high, it is difficult to promotes.Using biological particles With heat pump united heat supply method, the power of heat pump can be reduced to 4kw, it is not necessary to stand-by power supply, heat pump 42 degrees Celsius with Lower baking stage heat supply, improve the task performance of heat pump;The stage is toasted more than 42 degrees Celsius using biological particles burning Heat supply, the completely burned of biological particles is promoted, avoid biological particles a large amount of tar are produced in low-temperature burning and cause The use failure of combustor;Compared with common coal heating bulk curing barn, baking recruitment, energy-saving and emission-reduction advantage can be significantly reduced Substantially, improvement cost is relatively low, beneficial to popularization and application.
The content of the invention
It is an object of the present invention to carbon dioxide, sulfur dioxide dust granules for coal-fired bulk curing barn discharge at present Thing, environment is had undesirable effect, electric energy (air source heat pump, far infrared, electromagnetism), biomass, alcohol-based fuel etc. are renewable clean The bulk curing barn input cost of net energy source heat supply is high, needs a series of problems, such as electrical power is high, cost of material is high, there is provided one kind is used for The biological particles of bulk curing barn and heat pump united heat supply method.
The object of the present invention is achieved like this:Biological particles and heat pump united heat supply method for bulk curing barn, Biomass particle burning machine and air source heat pump are installed additional in common coal-fired barn, the stage are toasted below 42 degrees Celsius, using sky Air supply heat pump heat supply, stage of being toasted more than 42 degrees Celsius use biological particles combustion heat supplying.
In the present invention, biomass particle burning machine and air source heat pump are installed additional in common coal-fired barn;Biomass combustion machine Directly crater can be docked with the stove of existing bulk curing barn, realize that biological particles burning carries out heat supply to bulk curing barn; Air source heat pump main body is placed on outside bulk curing barn heating chamber, and evaporator is placed at barn moisture exhausting port to high-grade hydrofuge waste heat Utilized, condenser, which is located in heating chamber, to be used to carry out heat supply to bulk curing barn.
In the present invention, the tobacco leaf changing yellow stage in flue-cured tobacco modulated process, i.e., less than the 42 degrees Celsius baking stages, using air Source heat pump heat supply.
In the present invention, tobacco leaf fixation and dry muscle stage in flue-cured tobacco modulated process, i.e., more than 42 degrees Celsius are toasted the stage, Using biological particles combustion heat supplying, heat pump and biological particles burning combined heat during the stage hydrofuge.
In the present invention, when power failure is powered using stand-by power supply to bulk curing barn, the heat-supplying mode of bulk curing barn can be cut Change to biological particles combustion heat supplying.
In the present invention, computer heating control is carried out to heat pump and biomass particle burning machine with integrated-control apparatus, can be according to roasting The heat energy and hydrofuge demand in room are controlled to be switched with heat-supplying mode.
Beneficial effect
Compared with common coal heating bulk curing barn, it can significantly reduce baking recruitment and energy consumption, energy-saving and emission-reduction advantage are bright It is aobvious;Compared with heat pump heat supply bulk curing barn, heat pump task performance can be improved, reduces the power load needed for bulk curing barn, and Extra stand-by power supply need not be equipped with;Compared with biological particles heat supply bulk curing barn, the complete of biological particles is promoted Burning, avoid biological particles and the use failure that a large amount of tar cause combustor, waste heat recovery profit are produced in low-temperature burning With greatly improving;Improvement cost is relatively low, beneficial to popularization and application.
Embodiment
Technical solution of the present invention is further illustrated below in conjunction with specific embodiment.
Embodiment 1:
Biomass particle burning machine and air source heat pump are installed additional in common coal-fired barn;Biomass combustion machine will directly can go out Burner docks with the stove of existing bulk curing barn, realizes that biological particles burning carries out heat supply to bulk curing barn;Air source heat pump Main body is placed on outside bulk curing barn heating chamber, and evaporator is located at barn moisture exhausting port and hydrofuge waste heat is utilized, and condenser is placed It is used to carry out heat supply to bulk curing barn in heating chamber.Heat pump and biomass particle burning machine are added with integrated-control apparatus Thermal control, the tobacco leaf changing yellow stage in flue-cured tobacco modulated process, i.e., in less than 42 degrees Celsius baking stages, controlled and used by controller Air source heat pump heat supply, when having a power failure occurs in changing yellow stage, and bulk curing barn is powered using stand-by power supply, controller is by bulk curing barn Heat-supplying mode be switched to biological particles combustion heat supplying;Tobacco leaf fixation and dry muscle stage in flue-cured tobacco modulated process, i.e., 42 The stage is toasted more than degree Celsius, using biological particles combustion heat supplying, controller control heat pump and biological particles combustion during hydrofuge Burn combined heat.
