Description
Technical field
The oven dry heat pump of the utility model band finned tube belongs to art of heat pumps.
Background technology
In the process engineering of fireworks, need dry the gunpowder of fireworks usually, what existing drying gun powder equipment adopted is to produce steam with boiler; Be input to drying room through pipeline then and carry out drying; But since this drying gun powder equipment use be Boiler Steam as dry heat energy, vapor (steam) temperature is high, causes the temperature in the drying room too high easily; Gunpowder explodes easily, and is dangerous; Boiler produces steam through burning primary energy coal simultaneously, and not only energy waste is serious, and toxic emission is serious, contaminated environment.
The utility model content
The purpose of the utility model is to avoid the weak point of prior art, and provides a kind of safe, the oven dry heat pump of the band finned tube of energy-conserving and environment-protective.
The purpose of the utility model reaches through following measure, and the oven dry heat pump of band finned tube comprises that compressor, first heat exchanger, throttling arrangement, second heat exchanger constitute, and the exhaust outlet of compressor links to each other with the first heat exchanger refrigerant import; The first heat exchanger refrigerant exit is connected with the throttling arrangement import, and the outlet of throttling arrangement links to each other with the second heat exchanger refrigerant import, and the second heat exchanger refrigerant exit is connected to the return-air mouth of compressor; The first heat exchanger water inlet is connected with second water pipe, and the first heat exchanger outlet pipe links to each other with first water pipe, and second water pipe is provided with water pump; Water pump is connected to expansion tank; First water pipe connects finned tube, and second water pipe connects finned tube, and finned tube one end connects first water pipe; The finned tube other end connects second water pipe, parallel distribution between the finned tube.
The throttling arrangement of the utility model is electric expansion valve or heating power expansion valve.
First heat exchanger of the utility model is water-refrigerant heat exchanger.
The utility model is safe, and energy-conserving and environment-protective are a kind of novel drying gun powder heat pumps.
Description of drawings
Accompanying drawing 1 is the embodiment principle schematic of the utility model.
Accompanying drawing 2 is that the finned tube of the utility model connects floor map.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: compressor 1, first heat exchanger 2, throttling arrangement 3, second heat exchanger 4, first water pipe 5, second water pipe 6, finned tube 7, gunpowder drying room 8, water pump 9, expansion tank 10.
Shown in accompanying drawing 1, accompanying drawing 2, the oven dry heat pump of the utility model band finned tube comprises that compressor 1, first heat exchanger 2, throttling arrangement 3, second heat exchanger 4 constitute; The exhaust outlet of compressor 1 links to each other with the 2 refrigerant imports of first heat exchanger, and first heat exchanger, 2 refrigerant exits are connected with throttling arrangement 3 imports, and the outlet of throttling arrangement 3 links to each other with the 4 refrigerant imports of second heat exchanger; Second heat exchanger, 4 refrigerant exits are connected to the return-air mouth of compressor 1; First heat exchanger, 2 water inlets are connected with second water pipe 6, and first heat exchanger, 2 outlet pipes link to each other with first water pipe 5, and second water pipe 6 is provided with water pump 9; Water pump 9 is connected to expansion tank 10; Be provided with finned tube 7 in gunpowder drying room 8 bottoms, parallel distribution between finned tube 7 tube and tube, and finned tube 7 two ends are provided with A mouth and B mouth; The A mouth of finned tube 7 is connected with second water pipe 6, and the B mouth of finned tube 7 links to each other with first water pipe 5.
The drying gun powder operation logic:
The water that the while expansion tank is 10 li enters into water pump 9, enters into first heat exchanger, 2 inside through second water pipe 6 and carries out heat exchange, and the hot water after the heat exchange flow into first water pipe 5; B mouth through finned tube 7 enters into finned tube 7 inside then, this moment finned tube 7 distribute heats, with thermaltransmission mode heat supply in gunpowder drying room 8 of radiation; Then; After finned tube 7 heat radiation, inner hot water temperature reduces, after the A mouth through finned tube 7 flow into second water pipe 6 again; Enter into first heat exchanger 2 once more, constitute the circulation in water route.In this process, produce hot water through heat pump, be transported to finned tube 7 then, pass through finned tube 7 radiant heat transfer heats again to gunpowder drying room 8, reach the purpose of drying gun powder.Do like this, not only the temperature in the gunpowder drying room 8 can be too not high, safe; And heat pump is through from natural air, water or soil, obtaining low grade heat energy; Doing work with electric power produces hot water, and low, the non-exhaust emission that consumes energy real has reached energy-conserving and environment-protective.
Finned tube adopts Changsha ancient cooking vessel couplet heat energy technology Co., Ltd to produce tube thickness 2 ㎜, diameter of inner pipe 25 ㎜, outer tube diameter 50 ㎜.
