Abstract
The invention relates to a multifunctional ground heat pump drying device of heat energy project. Based on present drying device, it uses the condenser of heat pump to replace the heating element of present drying device to heat and dry the drying device. The invention can integrate the drying, refrigeration and heating as a whole. In the winter, it can use the heat pump and the evaporator to adsorb the lower temperature heat energy of the earth's surface to increase the high temperature heat energy of condenser to heat and dry the drying device; in the summer, it can use the heat pump to adsorb the heat energy of cold water at one end of said evaporator or the heat energy of air to reduce the temperature and condense at one end of condenser to release the heat energy to heat and dry the drying device; if not needing the drying process, it can process the condensation at another end of condenser to release the heat energy to attain hot water. Compared to the heating efficiency 1:3.5 of present heat pump, the invention can reach more than 300%.
Description
Affiliated technical field
The invention belongs to Thermal Power Engineering Field, particularly a kind of efficient, energy-saving multifunction drying plant that utilizes shallow layer geothermal energy as source heat pump heat.
Background technology
The thermal element of existing typical general drying plant is electric heater or superheated steam coil pipe.Principle as shown in Figure 1, the heat that blower fan 1 is produced thermal element 2 is delivered to drying baker 3 and is given article heating, drying in the drying baker.This electric heater or the superheated steam coil pipe of directly utilizing provides the drying plant of heat for oven dry, and be simple in structure.But the efficiency of heating surface of the heating element heater of this equipment causes operating cost higher relatively always below 100%.
Summary of the invention
The purpose of this invention is to provide a kind of thermal efficiency at the drying integrated equipment of multifunctional geothermal heat pump air-conditioner hot water more than 300%.
The present invention will solve the technical scheme that its technical problem adopts: on existing drying plant basis, utilize the condenser 7 of heat pump to replace the thermal element 2 of original dryer, utilize winter heat pump techniques by evaporimeter 20 and ground heat exchanger 16 absorb the low potential temperature geothermal energy of shallow surfaces promote for the high potential temperature heat energy of condenser 7 to the drying plant oven dry of heating; Utilize summer heat pump techniques at the heat of evaporimeter 20 1 end absorption refrigerating water or airborne heat and the cooling of lowering the temperature carries out the condensation heat release at condenser 7 one ends to give the drying plant heating, drying; If do not need to dry operation, carry out the condensation heat release at another condenser 15 and heat water.
The invention has the beneficial effects as follows: provide winter a kind of total Energy Efficiency Ratio at the drying integrated equipment of multifunction geothermal-energy heat pump hot water more than 300%, owing to effectively utilized the geothermal energy that is stored in shallow surface, total Energy Efficiency Ratio of this drying plant the efficiency of the operating efficiency of heat pump reached more than 1: 3.5, so can reach more than 300%; Provide summer a kind of Energy Efficiency Ratio at the oven dry of the air-conditioning more than 600% hot-water integration equipment.
Description of drawings
Below in conjunction with accompanying drawing specific embodiments of the present invention is described in further detail.
Fig. 1 is the schematic diagram of general drying plant.
Fig. 2 is a multifunctional heat pump drying apparatus using geothermal energy as heat source schematic diagram of the present invention.
The specific embodiment
With copper pipe the exhaust outlet of refrigeration compressor 5 is connected with condenser 7 one ends in being contained in drying baker 6, the other end of condenser 7 is connected with an end of condenser 15, condenser 15 other ends are connected with evaporimeter 20 1 ends with choke valve 17 backs by reservoir 12, the other end of evaporimeter 20 links to each other with compressor 5 air inlet pipe by gas-liquid separator 23, forms the closed circuit that heats of this heat pump drying plant.
Winter, the course of work of oven dry was: cold-producing medium is in evaporimeter 20 evaporations, absorb the low potential temperature geothermal energy of shallow surface by underground radiator 16, promoting through compressor 5 compression backs is high temperature and high pressure gas, carry out the condensation heat release in the condenser 7 in drying baker 6, and heat is passed to 13 pairs of article heating, dryings that need oven dry of drying roller by blower fan 8.
The course of work of producing hot water winter is: cold-producing medium is in evaporimeter 20 evaporations, absorb the low potential temperature geothermal energy of shallow surface by underground radiator 16, promote the high temperature and high pressure gas that is through compressor 5 compression backs, condensation heat release in condenser 15, cold water flows into from water pipe 9, hot water flows out from water pipe 10, thereby has reached the purpose of producing hot water.
The course of work of freeze summer, drying is: valve-off 18,19, open valve 21,22, and cold-producing medium absorbs the heat of chilled waters in the evaporimeter 20, by chilled water pipe 24 external coolings in evaporimeter 20 evaporations.Drying course is identical with winter.
