Abstract
A heat cycling greenhouse heating device is composed of a boiler, heat transfer oil, a high-temperature pump, a heat absorption pipeline, a heat transfer pipeline, heat exchange tubes and a waste heat reflux pipeline. A thermal insulating layer is additionally arranged on the outer wall of the boiler. One end of the heat absorption pipeline is communicated with the heat transfer oil in the boiler, the other end of the heat absorption pipeline is connected with an inlet of the high-temperature pump, and an outlet of the high-temperature pump is connected with one end of the heat transfer pipeline. The other end of the heat transfer pipeline is connected with the heat exchange tubes, the heat exchange tubes are in parallel connection and extend to be hung on the inner wall of a thermal insulating wall of a greenhouse, the other end of each heat exchange tube is connected with one end of the waste heat reflux pipeline, and the other end of the waste heat reflux pipeline is communicated with the heat transfer oil in the boiler. Heat energy generated by fuel through combustion is stored in the heat transfer oil, the high-temperature pump transmits the heat energy to the heat exchange tubes in a high-temperature hot oil mode through a pipeline, and the heat exchange tubes transmit heat to greenhouse space. After temperature transmission of the high-temperature hot oil to the greenhouse is completed, the heat returns to the boiler through the reflux pipeline, and waste heat can be recycled.
Description
Technical field
The utility model relates to a kind of heating plant, is specially the circulating-heating heating plant of green house, belongs to heat enginnering technical field.
Background technology
The ceiling lid of green house sealed light-transmitting gathers solar thermal energy, keeps heat energy here and promotes the temperature requirements of temperature of shed for plant etc.This in the southeast, South China is for the green house of planting, only depend on winter to collect solar energy and almost can meet the demand of plant to temperature; Arrive the winter of the northern areas such as North China because canopy is inside and outside, the temperature difference between is round the clock larger, for the invasion and attack and the temperature of shed that stop north wind run off, need to erect abundant insulated wall in booth east, west, north side; In colder season or area, depend alone and have the heat of solar energy in one's care and abundant insulated wall can not meet the temperature requirements in canopy far away.Therefore, vegetable growers have adopted the make a fire method of wall of rural area, dig ground kitchen range outward at canopy, on insulated wall, build quirk by laying bricks or stones by a side in canopy, and the way of the combustible that burns in ground kitchen range is the demand to temperature for canopy implants etc. of heating in canopy.But the supply of temperature for high and cold area of such way is also nowhere near, while running into especially sudden significantly cooling, cannot be at short notice by a relatively large margin be intensification in canopy, tend to therefore plant and be damaged by frost or freeze to death.Meanwhile, such heat-supplying mode is because be unidirectional straight-through, and the utilization rate of heat energy is lower, and a large amount of waste heats are directly drained by chimney, waste energy.
Summary of the invention
The utility model discloses a kind of circulating-heating greenhouse heating device, when being intended to guarantee that heat is supplied with when green house is heated by a relatively large margin, adopts heat carrier circulating-heating, has fully reclaimed waste heat, saves the energy.
The technical scheme that the utility model adopts is: device is made up of heat source unit and thermal source supply unit.Heat source unit is made up of boiler, conduction oil, and boiler casing is attached with heat-insulation layer.Thermal source supply unit is made up of high-temperature pump, heat absorbing conduit, heat supply pipeline, heat exchanger tube, afterheat return pipeline.One end of heat absorbing conduit is communicated with the conduction oil in boiler, the other end connects the import of high-temperature pump, high temperature delivery side of pump connects one end of heat supply pipeline, the other end of heat supply pipeline connects one end of heat exchanger tube, the in parallel extension of heat exchanger tube is suspended on greenhouse insulation inner wall, the other end of heat exchanger tube connects one end of afterheat return pipeline, and the other end of afterheat return pipeline is communicated with the conduction oil in boiler.
By fuel through burning produce heat energy store at conduction oil, high-temperature pump is delivered to heat exchanger tube heat energy with the form of high-temperature hot oil by pipeline, heat exchanger tube by heat propagation to green house space.High-temperature hot oil completes after the temperature propagation of green house, gets back to boiler through reflux line, and remaining waste heat is recycled utilization.
The beneficial effects of the utility model are: in guaranteeing high and cold area winter, while especially needing to heat by a relatively large margin for green house in the short time, heat is supplied with, conduction oil circulating-heating, saves heat time and the energy.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
Fig. 1 is traditional ground stove wall heating mode schematic diagram;
Fig. 2 is the utility model circulating-heating greenhouse heating device schematic diagram;
In figure 1, greenhouse insulation wall, 2, boiler, 3, high-temperature pump, 4, heat absorbing conduit, 5, afterheat return pipeline, 6, heat supply pipeline, 7, conduction oil, 8, heat exchanger tube, 9, kitchen range, 11, quirk, 12, chimney.
embodiment:
In the embodiment in figure 1, stove wall Heating system is made up of ground kitchen range 9, quirk 11, chimney 12 traditionally, ground kitchen range 9 is below ground level, fuel is in the fire box burning of ground kitchen range 9, flue gas and flame transmit through quirk 11, transmitting procedure flue gas and flame heating quirk 11 walls, temperature is preached to the space of green house by quirk 11 walls, and flue gas and after-heat are got rid of by chimney 12.Its disadvantage is programming rate and can heating load be subject to facility restriction itself, be difficult to guarantee the temperature requirements of green house in the time of particular case, also, because of the requirement of facility own, the draft of chimney 12 is better, the better burning of fire of its ground kitchen range 9, has just caused the waste of ground kitchen range 9 heat energy of burning more serious.
In the embodiment of Fig. 2, the utility model is made up of heat source unit and thermal source supply unit.Heat source unit is made up of boiler 2, conduction oil 7, and boiler 2 outer walls are attached with heat-insulation layer.Thermal source supply unit is made up of high-temperature pump 3, heat absorbing conduit 4, heat supply pipeline 6, heat exchanger tube 8, afterheat return pipeline 5.One end of heat absorbing conduit 3 is communicated with the conduction oil 7 in boiler 2, the other end connects the import of high-temperature pump 3, the outlet of high-temperature pump 3 connects one end of heat supply pipeline 6, the other end of heat supply pipeline 6 connects one end of heat exchanger tube 8, heat exchanger tube 8 is suspended on the extension in parallel of greenhouse insulation wall 1 inwall, the other end of heat exchanger tube 8 connects one end of afterheat return pipeline 5, and the other end of afterheat return pipeline 5 is communicated with the conduction oil 7 in boiler 2.
Embodiment 1: to the interior filling conduction oil 7 of boiler 2, start high-temperature pump 3 and allow conduction oil 7 after the driving of high-temperature pump 3 fills heat absorbing conduit 4, heat supply pipeline 6, heat exchanger tube 8, afterheat return pipeline 5, till conduction oil 7 is filled into the liquid level restriction of boiler 2.
