Description
Technical field
The utility model relates to phase-change material energy storage heat supply process field, relates in particular to a kind of carbon dioxide phase transformation excitation apparatus.
Background technology
At present, cross-season heat-storage technology mainly contains following a few class: artificial water tank water body, gravel accumulation of heat, soil thermal storage and underground reservoir accumulation of heat.Artificial water tank water body and gravel accumulation of heat have high heat capacity, good holding/latent heat releasing performance, the advantages such as stable performance, non-environmental-pollution.The mode of artificial water tank water body and gravel accumulation of heat, be by water or gravel deposit with water tank in, but water tank heat preserving engineering is difficult, cost is high, 10000m
3artificial water tank cost just up to ten million yuan.Soil thermal storage system adopts underground pipe that heat energy is saved in underground conventionally, the advantage of this technology is without artificial thermal storage equipment, cost is relatively low, but system heat loss is high, required accumulation of heat volume is large, to around ecological environment is influential, and geologic structure is had selectively, be only applicable to rock and saturation water soil environment.Utilize underground natural aqueous layer as hot water storage tank, have advantages of that cost is low, but harsh to geology environmental requirement, system operation is prone to the phenomenons such as plug well, corrosion and mould.Above cross-season heat-storage technology, due to technology or limiting factor economically, is difficult to promote.Therefore need badly development of new high-efficiency and economic across energy accumulating technique in season.

The specific embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.The element of describing in an accompanying drawing of the present utility model or a kind of embodiment and feature can combine with element and feature shown in one or more other accompanying drawing or embodiment.It should be noted that for purposes of clarity, in accompanying drawing and explanation, omitted and the utility model expression and description irrelevant, parts known to persons of ordinary skill in the art and processing.
The front view of the carbon dioxide phase transformation excitation apparatus that Fig. 1 provides for the utility model embodiment.As shown in Figure 1, the carbon dioxide phase transformation excitation apparatus that the utility model embodiment provides, comprise carbon dioxide caisson 1, on the exhaust outlet of carbon dioxide caisson 1, be connected with blast pipe 2, blast pipe 2 is connected with heat exchange department 4 away from the end of carbon dioxide caisson 1, is connected with pressure-reducing valve 3 on blast pipe 2.
Such scheme, has adopted phase-changing energy-storing technology, by the ACTIVE CONTROL to phase transformation, has broken away from the limitation of sensible heat accumulation of energy, has reached the object that prolonged low grade fever damages energy storage when greatly improving thermal storage density.Adopt such scheme across season energy-storage system build, use cost is low, long service life.
In actual use, this carbon dioxide phase transformation excitation apparatus can comprise carbon dioxide caisson 1, and carbon dioxide caisson 1 can be carbon dioxide storage tank, and its internal memory is put liquid carbon dioxide.
The tops such as carbon dioxide caisson 1 are provided with exhaust outlet, can connect valve the outer row of carbon dioxide is controlled on exhaust outlet.On valve, connect blast pipe 2, this blast pipe 2 communicates with exhaust outlet by valve, a heat exchange department 4 of end connection at blast pipe 2 away from carbon dioxide caisson 1, this heat exchange department 4 can be shell structure, be for example and without limitation to a metal box, the liquid CO 2 heat absorption of gasifying in this metal box, can lower the temperature to the object of its periphery this metal box.In when application, this metal box can be close to sidewall or the bottom surface of phase change medium container 5, carries out coolingly with the phase change medium in phase change medium container 5, makes phase change medium crystallization and discharges heat energy.
For the gasification rate to carbon dioxide, control, at heat exchange department 4, be connected with relief tube 6, be connected with pressure valve 7 on relief tube 6, be also connected with Pressure gauge 8 on relief tube 6, Pressure gauge 8 arranges near pressure valve 7.The pressure value showing according to Pressure gauge 8 is controlled the aperture of relief valve, and then controls the gasification rate of carbon dioxide.Pressure gauge 8 arranges near pressure valve 7, makes the force value of the carbon dioxide that records more accurate, and real-time is good.
