Description
Technical field
The utility model relates to heat-pump apparatus is applied to the evaporation field, is a kind of efficient use device of the heat of transformation of water.
Background technology
The drying of material is that the moisture that will contain as solid particle materials such as foodstuff grain, coal ores is heated to be gaseous state, belongs to a kind of of evaporation, because the gasification of water need absorb a large amount of heat, therefore evaporation belongs to the industry of high energy consumption.Dry means at present commonly used are to adopt the hot blast heating means, by burning or electric heating with air heat after, material is blown in air blast, makes its internal moisture gasification realize drying and dehydrating; But the thermal efficiency of this heat change method is very low, has only 20%～40% usually.And vapor evaporated since temperature with to be evaporated material close, according to the law of thermodynamics, the isothermal medium can't be realized heat exchange with material, therefore in industry, can't the steam of this little temperature difference low-pressure effectively be utilized, usually can only directly discharge, the steam that causes these suctions to hold huge heat of gasification can not be recovered utilization.The low side technology of this extensive style has caused the serious waste of heat energy, for the production technology of big evaporation capacity, has no idea to reduce the rigidity cost expenditure of coal electricity, can not implement the High-Interest Object of carbon reduction.
In some vacuum evaporation drying processes, need big rate of air sucked in required vavuum pump, but therefore existing conventional vacuum pump can't be used in the drying equipment of huge water evaporation capacity because inspiratory capacity is limited, more can't realize the utilization again to steam.The vapour injection compressor reducer, claim heat pump again, working media mainly is a steam, high pressure draught sprays at a high speed from nozzle during work, low-pressure gas around the driving nozzle, two strands of air-flows mix supercharging in mixing chamber and diffuser, under the condition that has consumed certain working gas, improved the low-pressure gas pressure and temperature that enters injector from suction inlet.Jet ejector is simple and practical, is widely used in manufacturing and keeps vacuum, low-pressure steam to utilize and refrigerating field again industrial.When jet ejector at compression ratio 1.2, when expansion ratio is used more than or equal to 10 running parameter section, it is huge to have rate of air sucked in required, the working steam that consumes is extremely low, the high remarkable advantage that waits of Energy Efficiency Ratio, but it is same because compression ratio is low excessively, outlet pressure is low, therefore the steam of a large amount of little temperature difference low pressure conditions of extracting out the heat release of can not in the medium pipeline of back segment heat exchanger, liquefying, specifically, water at low temperature steam from the output of the mixed gas outlet of jet ejector, be confined to two actual conditionses restrictions of low-pressure in the little temperature difference and pipeline inside and outside the pipeline in heat exchanger tube the inside, can't condensation heat release in heat exchange manifold, and go to outside the heat exchanger with gaseous state, therefore injected compressor reducer can't be assembled the valuable steam that reclaims acquisition and inhale the huge heat of gasification heat energy utilization that holds.So jet ejector is that the vavuum pump of the simple big rate of air sucked in required of conduct is used under this operating mode, and heat energy is not brought into play the effect of heat pump by in vain waste at all, can not reach the dual technology purpose of not only vacuum evaporation but also heat pump heat exchange.
