Abstract
The invention discloses a heat pump drying system. The heat pump drying system comprises a drying chamber, a heat pump system and an air heat exchanger. The heat pump drying system is characterized in that the drying chamber comprises a high-temperature section and a normal-temperature section, air heat exchange fins are mounted on the normal-temperature section, an evaporator and a condenser are enclosed in a gas pipeline in the heat pump system, and the air heat exchanger is positioned on the gas pipeline between the evaporator and the condenser. The heat pump drying system can make full use of heat in atmosphere, and dehumidification ratio of the heat pump drying system is much higher than that of an existing heat pump drying system.
Description
Technical field
The present invention relates to a kind of drying system, particularly relate to a kind of Analysis of Heat Pump Drying System.
Background technology
Analysis of Heat Pump Drying System is a kind of common drying system, and its important indicator is dehumidifying rate.According to version in 2007 " modern dry technology " one book sum up, the dehumidifying rate of existing Analysis of Heat Pump Drying System is generally at 2 ~ 3kg water/kwh.In order to improve dehumidifying rate, this patent proposes the Analysis of Heat Pump Drying System of heat in the abundant air of a kind of energy of meter, to save energy consumption further.
Although gas--gas heat exchange needs the heat exchange area of super large, needs longtime running like this and without the system of benefit for drying sludge, and the reduction of running cost is important more than one-time investment.
Summary of the invention
Technical problem to be solved by this invention is to provide the Analysis of Heat Pump Drying System of heat in the abundant air of a kind of energy, comprising: dryness storehouse, heat pump and air heat exchanger, is characterized in that:
Described dryness storehouse is made up of two parts, and a part is high temperature section, and a part is normal temperature section; In described normal temperature section, air heat-exchange sheet is installed;
In described heat pump, evaporimeter and condenser are closed in gas piping, on the gas piping of described air heat exchanger between described evaporimeter and described condenser.
Compared with prior art, the invention has the beneficial effects as follows: except the energy that operation of heat pump drops into, the heat in air can also be utilized, further joint medicine energy consumption.
Accompanying drawing explanation
Fig. 1 is the structural representation of the Analysis of Heat Pump Drying System of the embodiment of the present invention.
Detailed description of the invention
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
Embodiment:
Analysis of Heat Pump Drying System as shown in Figure 1, comprising: dryness storehouse 1, heat pump 2 and air heat exchanger 3, is characterized in that:
Dryness storehouse 1 is made up of two parts, and a part is high temperature section 1-1, and a part is normal temperature section 1-2; On described normal temperature section 1-2, air heat-exchange sheet 1-3 is installed;
In heat pump 2, evaporimeter 2-1 and condenser 2-2 is closed in gas piping, on the gas piping of air heat exchanger 3 between evaporimeter 2-1 and condenser 2-2.
Briefly introduce as follows to the course of work of the present embodiment below:
Dry gas from dryness storehouse 1 out after, first through the evaporimeter 2-1 of heat pump 2, by with evaporimeter 2-1 heat exchange after, dry gas is cooled to below atmospheric temperature, and meanwhile, moisture content contained in gas is condensated into liquid, removes from system.Subsequently, dry gas enters air heat exchanger 3, and because the temperature of dry gas is lower than atmospheric temperature, therefore, dry gas will absorb heat from air, finally, makes its temperature close with atmospheric temperature; And now the humidity of dry gas far below air.Then, dry gas is condenser 2-2 in heat pump 2, by with condenser 2-2 heat exchange after, dry gas is heated, and its temperature improves further; Now the relative humidity of dry gas is lower.The dry gas that relative humidity is very low, enters the high temperature section 1-1 of dryness storehouse 1, carries out drying to material.Along with the evaporation of moisture content, the temperature of dry gas reduces, until its temperature is close with atmospheric temperature, now, dry gas enters normal temperature section 1-2.
Dry gas is in normal temperature section 1-2, and because its relative humidity is still very little, therefore, dry gas still has very strong wettability power, and still can make the water evaporates in material, it is air-dry that its operation principle is equivalent to normal temperature; Due to the water evaporates heat absorption in material, the temperature of material and dry gas will be caused to reduce, thus make dry gas temperature a little less than atmospheric temperature; Now, by air heat-exchange sheet 1-3, dry gas can absorb heat again from air.Finally, temperature and dry gas that relative humidity higher close with atmospheric temperature, flows through again the evaporimeter 2-1 of heat pump 2.By with evaporimeter 2-1 heat exchange after, dry gas is cooled to below atmospheric temperature, and meanwhile, moisture content contained in gas is condensated into liquid, removes from system.Subsequently, dry gas enters next circulation.
The method of operation of dryness storehouse 1 is: during discharging, is taken out by the material in high temperature section 1-1, and the material in normal temperature section 1-2 is moved into high temperature section 1-1, and then, virgin material enters normal temperature section 1-2, so circulates.
From above-mentioned running, may find out, except the energy input by operating heat pump is used to except drying, this patent system fully can also absorb heat in air for drying.Therefore, the dehumidifying rate of this patent system comparatively existing system increase exponentially.
Above embodiment is only exemplary embodiment of the present invention, and be not used in restriction the present invention, protection scope of the present invention is defined by the claims.Those skilled in the art can in essence of the present invention and protection domain, and make various amendment or equivalent replacement to the present invention, this amendment or equivalent replacement also should be considered as dropping in protection scope of the present invention.
