Description
Technical field
The invention belongs to senior middle school's warm pump drying field, particularly to double source enclosed efficient energy-saving drying system.Application model
Enclose for: senior middle school warm pump drying dehumidification.Being dried the article scope dried is grain, vegetable and fruit, Nicotiana tabacum L., bacon, aquatic products, clothes
Dress cloth, Chinese crude drug, timber, mud coal, various industrial or agricultural raw material and product etc..
Background technology
The category that dry materials is dried is extremely extensively and enormous amount, the energy consumption that the whole society dries for dry materials
The hugest.Having data to show, developed country accounts between the 7%-15% of total energy consumption for the energy consumption that dry materials is dried, averagely
It is 12%.The annual electricity generating capacity of China is about 5,000,000,000,000 degree now, as estimated for electric energy consumption is gross generation 8% dried,
The electric power energy consumption in the whole nation dried for electrical heating the most every year is 400,000,000,000 degree, is equivalent to the generated energy in power station, 5 Yangtze River Gorges；
The fuel such as coal being simultaneously used for drying also is a quantity the hugest.
Traditional dry materials dehumidifying usually electricity consumption or fuel is carried out with mode of heating.General capacity usage ratio all than
Relatively low, the capacity usage ratio of mode of heating greatly below 70%, the most even as low as less than 40%, some occasion such as home laundry
Dry and also need to the damp atmosphere discharged is carried out moisture condensation process again, very inconvenient.1 degree of heat of being converted into of electricity is
3600KJ, the heat needed for 1 kilogram of aqueous water evaporation is about 2400KJ, so electricity consumption heating, drying, entirely without thermal loss
In the case of, 1 degree of electric energy is dehydrated 1.5 kilograms；And actually in drying course, inevitably have substantial amounts of heat to dissipate,
The drying efficiency that electrical heating is dried, typically between 1 degree of electric dehydration 0.6-1.2 kilogram, is averagely about 0.8 kilogram.
Heat pump drying technology is to utilize the energy of electricity, with heat pump assembly, heat is warm to high temperature heat source conveying from low-temperature heat source
The technology of amount, a electricity can carry several parts of heat, compares general electrical heating and dries the energy consumption that can save more than 50%, simultaneously
Condenser heating and the double effects of vaporizer dehumidifying can be had concurrently, be the developing direction of following drying technology.
Because heat pump drying is an emerging technology, the exploitation application time is shorter, fails to fill to the basic principle of heat pump drying
Deep understanding is divided to grasp, so the potentiality of heat pump drying technology fail to fully play.
Heat pump drying equipment conventional on market can be roughly divided into two classes: A class is open, B class is closed.
A class heat pump drying device approximately as: so-called open, device i.e. has wind pipe or the air-out of a band blower fan
Mouthful, the hot and humid gas in baking oven is constantly drawn out of from wind pipe and enters eventually in air, has equivalent simultaneously
The new wind of air of low temperature and low humidity is inhaled in oven ncavity, and the gas in baking oven constantly swaps with atmospheric air.Heat
Pumping system has the outer vaporizer of a band blower fan outside baking oven, if the hot and humid gas in baking oven without outer vaporizer and changes
Hot device and be directly discharged in air, then the heat being discharged gas is not used, and outer vaporizer is completely from air
Middle draw heat.If, with the heat in the hot and humid gas being discharged, substantially there is following several ways: 1, there is no air
Air flows through outer vaporizer, and the hot and humid gas being only discharged drains emptying into air after flowing through outer vaporizer, showing of gas
Latent heat in heat and gas moisture is absorbed by outer vaporizer and is discharged in baking oven by condenser, a key features of the manner
Being intended to the air themperature in maintenance baking oven and enthalpy does not declines, the leaving air temp of vaporizer must drop to equal to or less than air
Ambient temperature, the evaporator refrigerant temperature that the evaporator refrigerant temperature of vaporizer directly absorbs heat with vaporizer from air is more or less the same；
2, the hot and humid gas being discharged again passes through vaporizer after adding atmospheric air mixing, and vaporizer is from the mixed gas flow through
Draw heat, then mixed gas drains emptying into air, and the manner makes the gas temperature flowing through vaporizer higher than atmospheric temperature, carries
High COP；3, the hot and humid gas wind new with the air being inhaled into being discharged first carries out heat friendship in a sensible heat exchanger
After changing, hot and humid gas again passes through outer vaporizer or directly drains emptying into air, exists completely as directly emptied outer vaporizer
Absorbing heat in air, the new wind of the manner is improved through heat-exchange temperature, the hot and humid gas discharged in having reclaimed baking oven
Partial heat.Above-mentioned several Application way all makes the heat in the hot and humid gas being discharged obtain a certain degree of utilization,
But compared with directly emptying with hot and humid gas, the effect of increase is extremely limited, the heating energy efficiency ratio of heat pump is substantially by greatly
Temperature is restricted, and drying effect is changed by the new wind i.e. humidity of atmospheric air simultaneously is affected.The result caused is: if wanted
Make the i.e. COP of heat pump Energy Efficiency Ratio high, then the high-low temperature difference of coolant can not be big, namely the air themperature in baking oven compares ambient temperature
Can not exceed too many, and the temperature in baking oven is the highest, then the effect of removal moisture drying is the most poor；Or gas temperature in baking oven
Higher, but in case, air themperature is very big with the temperature difference of ambient temperature, then and the coolant high/low temperature temperature difference of heat pump is big, Energy Efficiency Ratio
COP is low.
In a word: the open heat pump drying device of A class compares the electric heating drying machine of routine, energy profit is greatly improved
By rate, fractional energy savings is more than 50%, but general effect is less desirable, is restricted by relatively low ambient temperature, weighs total soma
The SMER of dry effect i.e. consumes the drying and dehydrating amount that often degree electricity obtains, it is impossible to the highest, and (3 is public at 3KGH2O/KWH for general SMER
Jin water/kilowatt-hour) below, SMER is averagely about 2.5, and winter is below 2.
B class heat pump dry device approximately as: so-called closed, i.e. air in baking oven is isolated with outside atmosphere substantially,
Its representative products is domestic heat pump dryer, it is characterized in that, extract heat in the vaporizer of the described device not air from baking oven
Amount；Having a circulation return air pipeline, vaporizer is arranged in return air duct, and condenser, in the downstream of the vaporizer of return air duct, steams
Sending out device and condenser shares a blower fan, evaporation air quantity is equal with condensation air quantity, and the hot and humid gas of oven ncavity is from return air
The import of pipeline flows into, and through vaporizer cool-down dehumidification, again passes through condenser heat temperature raising, returns to oven ncavity.Its advantage is
Being affected relatively small by ambient temperature and humidity, the heat that the aqueous water carburation by evaporation being dried in material is consumed is followed
Ring utilizes, and drying effect is basicly stable.Shortcoming is that atmosphere temperature rising is very slow in baking oven, and the heat that oven ncavity is obtained is heat pump
The heat that converted of energy that device acting consumes, device bring into operation after in baking oven the long-time temperature of air relatively low, also make stream
The gas temperature crossing vaporizer in return air duct is relatively low, and latent heat/sensible heat ratio that vaporizer absorbs in heat is the lowest, and drying removes
Wet weak effect, drying rate is slow.Especially because condenser and vaporizer share a blower fan, condensation air quantity and evaporation air quantity phase
Meanwhile, the latent heat absorbed such as vaporizer more than sensible heat, the air inlet/outlet temperature difference of condenser be 2.5 times of the vaporizer air inlet/outlet temperature difference with
On, the leaving air temp making condenser is the highest thus coolant condensation temperature is the highest causes heat pump Energy Efficiency Ratio to decline；Such as vaporizer
The latent heat absorbed is less than sensible heat, although be avoided that the drawback that condenser leaving air temp is the highest, but latent heat/sensible heat is less than 1, makes baking oven
Conversion ratio between latent heat and the sensible heat of interior air lowers, and causes water removal effect to be deteriorated.Total effect and A class open devices phase
When: the closed heat pump drying device of B class dries energy-conservation more than 50% compared with electrical heating, and SMER is about 2 to 2.5, difficult more than 3,
Especially in winter, being affected by ambient temperature, drying effect is worse.
