Description
Technical Field
The utility model relates to a drying equipment, especially a frostless air source heat pump hybrid heating baking house.
Background
The air source heat pump is an efficient energy-saving device and is commonly used for heating a drying room, but the operation effect of the air source heat pump is not ideal after decades of operation practices. The main reason is that the air source heat pump is likely to cause unstable operation and poor reliability of the unit due to frosting and defrosting of the evaporator in winter. When the air source heat pump works, the evaporator absorbs the heat of the surrounding air, and when the outdoor temperature is lower than 10 ℃ and the relative humidity is high, the surface of the evaporator is most prone to frosting. After the evaporator frosts, the frost layer is continuously thickened, so that the thermal resistance is increased, the air flow resistance is increased, the heat supply capacity and the energy efficiency ratio of a unit are reduced, and the energy waste is caused.
The common defrosting methods mainly comprise a reverse cycle defrosting method, a hot gas bypass defrosting method, a heating defrosting method and the like. The reverse cycle defrosting method has long defrosting time, and the drying room stops heating and drying during defrosting, so the system has poor operation reliability. The hot gas bypass defrosting method has long defrosting time, the drying room stops heating and drying during defrosting, and the compressor runs under high load during defrosting, so the service life is short. The heating defrosting method has high power consumption and high cost. In addition, the invention also discloses a method disclosed in the invention patent of 'fireworks and crackers drying room using air source heat pump as heat source' in Chinese patent No. 2009100444675, namely, a plurality of groups of standby evaporators are adopted, the plurality of groups of standby evaporators are not used at ordinary times, and are only used when the evaporators frost is formed, so that the cost of equipment is increased, and the effect is not great. To date, there is no ideal defrosting method.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a frostless air source heat pump hybrid heating drying room which is simple in structure, safe and reliable.
The utility model adopts the following technical scheme.
A frostless air source heat pump hybrid heating drying room comprises a drying room, an air source heat pump heating system comprising an evaporator, a compressor, a condenser and a throttling device, and further comprises an oil pump, an electric heating oil tank and a hot oil radiator, wherein the hot oil radiator is arranged beside the condenser, the electric heating oil tank is arranged beside the evaporator, and a movable heat insulation plate is arranged between the electric heating oil tank and the evaporator.
Compared with the prior art, the utility model has the advantages of simple structure, the reliability is high, and air source heat pump evaporimeter is not frosted winter.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a frostless air source heat pump hybrid heating drying room has a drying room 1 and an air source heat pump heating system including an evaporator 8, a compressor 12, a condenser 19 and a throttling device 14, the evaporator 8 installed in a main cabinet 9 is connected to the compressor 12 through a pipe B11, the compressor 12 is connected to the condenser 19 installed in a heating cabinet 20 through a pipe D15, the condenser 19 is connected to the throttling device 14 through a pipe E16, and the throttling device 14 is connected to the evaporator 8 through a pipe C13. The front of the evaporator 8 is provided with a fan 10, the rear of the evaporator 8 is provided with a movable heat insulation plate 7, the rear of the movable heat insulation plate 7 is provided with an electric heating oil tank 6, the electric heating oil tank 6 is connected with an oil pump (not shown in the figure), and the oil pump is connected with an oil storage tank (not shown in the figure). The electric heating oil tank 6 is connected to the hot oil radiator 4 installed above the condenser 19 through a pipe a5 and a pipe F17. The hot air supply fan 3 sends heat generated by the condenser 19 and the hot oil radiator 4 in the heating box 20 into the drying room 1 through the air pipe 2, and the residual heat pumping fan 18 sends residual heat in the drying room 1 into the heating box 20 through the air pipe 21. The air source heat pump heating system and the hot oil heating system are mixed to heat the drying room, so that the production rate is improved, in winter, the movable heat insulation plate 7 is pulled out, and the evaporator 8 is prevented from frosting due to the waste heat of the electric heating oil tank 6.
