Description

Double source closed recovery drying system
Technical field
This utility model belongs to senior middle school's warm pump drying field, particularly to double source closed recovery drying system.Application model Enclose for:Senior middle school warms pump drying dehumidification.It is grain, vegetable and fruit, Nicotiana tabacum L., bacon, aquatic products, clothes that the article scope dried is dried Dress cloth, Chinese crude drug, timber, mud coal, various industrial or agricultural raw material and product etc..
Background technology
Extremely extensively and enormous amount, the whole society is used for the energy consumption that dry materials are dried to the category that dry materials are dried Very huge.Data is had to show, the energy consumption that developed country is used for dry materials drying accounts between the 7%-15% of total energy consumption, averagely For 12%.The annual electricity generating capacity of China is about 5,000,000,000,000 degree now, and such as the electric energy consumption for drying is 8% estimation of gross generation, The electric power energy consumption being then used for the whole nation that electrical heating is dried every year is 400,000,000,000 degree, is equivalent to the generated energy in 5 Yangtze River Gorges power station; Being simultaneously used for the fuel such as the coal of drying is also an extremely huge quantity.
Traditional dry materials dehumidifying is 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 big below 70%, sometimes even as low as less than 40%, some occasions 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 liquid water evaporation is about 2400KJ, so electricity consumption heating, drying, does not have thermal loss completely 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 0.6-1.2 kilogram of 1 degree of electric dehydration, is averagely about 0.8 kilogram.
Heat pump drying technology is the energy using electricity, with heat pump assembly, to high temperature heat source, heat is conveyed heat from low-temperature heat source The technology of amount, a electricity can convey several parts of heat, compare general electrical heating and dry the energy consumption that can save more than 50%, simultaneously Condenser heating and the double effectses of vaporizer dehumidifying can be had concurrently, be the developing direction of following drying technology.
Because heat pump drying is an emerging technology, the development and application time is shorter, and the basic principle of heat pump drying is failed to fill Deep understanding is divided to grasp, so the potentiality of heat pump drying technology fail to fully play.
On market, conventional heat pump drying equipment 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, there are a wind pipe with blower fan or air-out in device 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 air fresh air of low temperature and low humidity is inhaled in oven ncavity, and the gas in baking oven is constantly swapped with atmospheric air.Heat Pumping system has an outer vaporizer with 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 completely, and outer vaporizer is completely from air Middle draw heat.If using the heat in the hot and humid gas being discharged, substantially having following several ways:1st, 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, gas aobvious Latent heat in heat and gas moisture is absorbed by outer vaporizer and is discharged in baking oven by condenser, key features of the manner The air themperature being intended in maintenance baking oven and enthalpy do not decline, and the leaving air temp of vaporizer must drop to equal to or less than air Ambient temperature, directly the evaporator refrigerant temperature of heat absorption from air is more or less the same for the evaporator refrigerant temperature of vaporizer and vaporizer; 2nd, the hot and humid gas being discharged again passes through vaporizer after adding atmospheric air mixing, and vaporizer is from the mixed gas flowing through Draw heat, then mixed gas drain emptying into air, the gas temperature that the manner makes to flow through vaporizer is higher than atmospheric temperature, carries High COP;3rd, the hot and humid gas being discharged first carries out heat friendship with the air fresh air being inhaled in a sensible heat exchanger After changing, hot and humid gas again passes through outer vaporizer or directly drains emptying into air, such as directly empties then outer vaporizer and exists completely Heat is absorbed, the manner fresh air is improved through heat-exchange temperature, has reclaimed the hot and humid gas discharged in baking oven in air 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, and the heating energy efficiency ratio of heat pump is substantially big Temperature degree is restricted, and drying effect is changed by the humidity that fresh air is atmospheric air and affected simultaneously.The result leading to is:If will Heat pump Energy Efficiency Ratio is made to be that COP is 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 not high, then the effect of removal moisture drying is just 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, and energy profit is greatly improved With 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 consumes the drying and dehydrating amount often spending electricity acquisition it is impossible to very high, and (3 is public in 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, that is, the air in baking oven is isolated with outside atmosphere substantially, Its representative products is domestic heat pump dryer, it is characterized in that, the vaporizer of described device not extract heat in the air from baking oven Amount;There is a circulation return air pipeline, vaporizer is arranged in return air duct, the downstream of the vaporizer in return air duct for the condenser, steam Send out device and condenser shares a blower fan, evaporation air quantity and condensation air quantity are equal, 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 Affected relatively small by ambient temperature and humidity, the heat that the aqueous water carburation by evaporation in dried material is consumed is followed Ring utilizes, and drying effect is basicly stable.Shortcoming is that in baking oven, atmosphere temperature rising is very slow, 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 the long-time temperature of air is relatively low in baking oven, 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 very low, and drying removes Wet effect is poor, and 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 as vaporizer absorbs is 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 too high to lead to heat pump Energy Efficiency Ratio to decline thus coolant condensation temperature is too high;As vaporizer The latent heat absorbing is less than sensible heat although being avoided that the drawbacks of condenser leaving air temp is too high, but latent heat/sensible heat is less than 1, makes baking oven Conversion ratio between the latent heat of interior air and sensible heat lowers, and leads to 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, SMER about 2 to 2.5, difficult more than 3, Especially in winter, affected by ambient temperature, drying effect is worse.
