Technical field:
The present invention relates to utilize the technical field of solar energy, specifically a kind of solar energy heat storage device and manufacture method thereof.
Background technology:
It is key subjects of a lot of green energy resources (solar energy, wind energy) exploitation that energy stores.One of them important channel is the storage of heat energy, particularly conversion of solar energy is become behind the heat energy input heat accumulation facility to preserve.Here the key index of heat accumulation equipment is the cost of each units of heat storage capacity.

A scheme is to adopt cement to make the solid heat-storage medium, and buries the sealing metal pipeline underground as the conduction oil passage in cement.Cement and pipeline closely contact to realize the heat exchange between cement and the conduction oil.Because the restriction of cement heat conductivility, pipeline must reach quite high density in cement, this makes the cost of in existing actual product pipeline and conduction oil considerably beyond the cost of heat-storage medium cement, the restriction of cost simultaneously has a strong impact on the efficient of heat exchange, make heat accumulation equipment can not make full use of the heat storage potentiality of medium, thereby further raise cost.
Existing another scheme is not use metallic conduit, allows the solid heat-storage medium of rock or common fragment of brick directly be infiltrated in the conduction oil, conduction oil is circulated between the slit of solid dielectric realize heat exchange.This way obtains effective heat exchange easily, also can save the cost of metal catheter, but owing to a large amount of hole in the solid dielectric, soaks into hole and need consume a large amount of conduction oils, and the consumption of generally by volume calculating conduction oil is not less than 15% of heat accumulation equipment.This makes conduction oil consumption become the prime cost of heat accumulation equipment equally, and the impurity in the building stones with can pollute conduction oil after the conduction oil large tracts of land contacts and cause system pipeline and the heat exchange surface fouling was lost efficacy, system and conduction oil are seriously descended service life, increase cost.
At the solar energy heat-storage equipment more than 400 ℃, the general fusing nitrate that adopts is made conductive fluid for operating temperature.Because the cost of fusing nitrate is lower, can directly make heat-storage medium with conductive fluid, promptly make thermal storage device with large-scale flow container.But the cost of making is still apparently higher than the solid heat-storage medium like this, and the security threat that concentrated storage caused of a large amount of high temperature melting nitrate also is very important.
Summary of the invention:
The purpose of this invention is to provide a kind of solar energy heat storage device and manufacture method thereof, it can will directly be infiltrated on fragment of brick in the mobile high temperature heat-conducting liquid as the solid heat-storage medium in the thermmal storage device, and do not add metallic conduit and isolate, improve the liquid-consumed and fouling that conductive fluid infiltration brick body inner pore causes thereby reach.
To achieve these goals, technical scheme of the present invention is: a kind of solar energy heat storage device is characterized by: described thermmal storage device has the metal shell of a sealing, offers two conductive fluid outlets on this metal shell, one of them is a cold side outlet, and another is the hot junction outlet; Be provided with the solid heat-storage medium in metal shell, this solid heat-storage medium is made of polylith solid heat accumulation fragment of brick, and the material of heat accumulation fragment of brick is the mixture of glass or glass and sandstone; The inside of heat accumulation fragment of brick or surface are provided with duct, groove or the breach of at least 2 roads for conductive fluid circulation, and the duct of heat accumulation fragment of brick, groove or breach make and form communication passage for the conductive fluid circulation between the inner or adjacent heat accumulation fragment of brick of heat accumulation fragment of brick.

Fig. 1 is a heat-storing device schematic diagram among the present invention.
Fig. 2 is the heat accumulation fragment of brick schematic diagram among Fig. 1.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing.
Mark 1 in the accompanying drawing is the main body heat storage brick, and 2 are the groove as the conductive fluid passage, and 3 is bead or the small-sized fragment of brick near exit, cold and hot two ends, and 4 is the sealing metal shell, and 5 is thermal insulation layer, and 6 is the cold side outlet pipeline, and 7 is the hot junction outlet conduit.
The present invention is a kind of solar energy heat storage device, it is characterized by: described thermmal storage device has the metal shell of a sealing, offers two conductive fluid outlets on this metal shell, and one of them is a cold side outlet, and another is the hot junction outlet; Be provided with the solid heat-storage medium in metal shell, this solid heat-storage medium is made of polylith solid heat accumulation fragment of brick, and the material of heat accumulation fragment of brick is the mixture of glass or glass and sandstone; The inside of heat accumulation fragment of brick or surface are provided with duct, groove or the breach of at least 2 roads for conductive fluid circulation, and the duct of heat accumulation fragment of brick, groove or breach make and form communication passage for the conductive fluid circulation between the inner or adjacent heat accumulation fragment of brick of heat accumulation fragment of brick.Conductive fluid is the conduction oil of prior art or the nitrate of fusing during enforcement; In metal shell, be provided with bead or glass blocks near cold side outlet and exit, hot junction; At metal shell outer wrap heat-barrier material; The solid heat-storage medium occupies 90% of metal shell inner space volume at least; Glass content in the mixture composition heat accumulation fragment of brick of glass and sandstone is greater than 30%, and sandstone is a granite.Preferable heat accumulation fragment of brick is a cuboid as shown in Figure 2, and thickness is 4cm, and height and width respectively are 20cm.4 heat conduction liquid baths are established on every limit, and the degree of depth and the width of every groove are 3.5mm.Heat-storing device is that the length and width height respectively is 0.6 meter a square, and can is welded into the thick galvanized steel plain sheet of aluminizing of 0.5mm, and closely fill in the mode that does not add bonding with above-mentioned heat storage brick inside.The metallic conduit that the upper and lower of device is respectively drawn a 24mm diameter exports as conduction oil, and the below is a cold junction, and the top is the hot junction.Can is outside heat insulation with the thick glass fibre cotton parcel of 25cm.Heat-storing device inside is respectively staying 10 liters space not fill out heat storage brick near exit, cold and hot two ends, and fills with the bead of 10mm diameter.
Survey factually, the heat storage brick of Sheng Chaning can tolerate brick body inside effectively and be no more than 40 ℃ thermograde like this.When this thermograde surpassed 60 ℃, heat storage brick is local a small amount of crack to occur, but does not disintegrate, and does not also influence thermal storage performance.On the other hand, the bead of the 10mm diameter thermograde that can tolerate is above 80 ℃.
Heat-storing device among the present invention seals with metal shell, and the conductive fluid in the holdout device leaks, as shown in Figure 1.The outside topped heat-barrier material of metal shell is heat insulation.Therefore the present invention is applicable to that mainly conductive fluid do not pressurize or only add the system of low pressure (being lower than three atmospheric pressure), otherwise metal shell need be made high-pressure-resistant vessel, increases cost greatly.According to the characteristic of commercially available all kinds of conduction oils, non-pressurized conduction oil operating temperature need be limited in (low pressure conduction oil operating temperature is no more than 385 ℃) below 350 ℃ usually.This operating temperature is used for middle-size and small-size solar heat Electricity Federation to be sent out system and is enough to meet the demands, but the large-sized solar electricity generation system is slightly disliked not enough.More than the temperature, need to adopt high-temperature low-pressure liquid to make conductive fluid at this as fusing nitrate.The fragment of brick surface can be carved with some grooves as shown in Figure 2, the preferable 3-8 bar groove that is chosen as of some grooves, described polylith solid heat accumulation fragment of brick can adopt several piece to hundreds of, the preferable 15-180 piece that is chosen as, after the fragment of brick sign indicating number became heat-storing device, these grooves formed the conductive fluid passage.Fragment of brick inside also can be provided with some ducts as the conductive fluid passage.It is normative reference that the design in groove or duct is no more than 10% with the capacity of conductive fluid in heat-storing device.The consumption that reduces conductive fluid not only helps to reduce cost, and has also improved the security performance of heat-storing device simultaneously, in case because the conductive fluid leakage rate when having reduced outer casing rupture.The groove design of optimizing can make the consumption of conductive fluid drop to below 4% of total capacity.A simple and reliable concrete making way of heat storage brick is to make above-mentioned heat storage brick with glass fully, particularly the discarded glass that reclaims by fusing.Po Sui variegated glass does not wherein reclaim as garbage disposal contaminated environment then, reclaims to be difficult to find suitable other to utilize approach again, therefore can be used for making heat storage brick by extremely low cost.Heat accumulation does not all have special requirement to the composition and the color of glass material, even impurity such as bottle cap contained in the material are also had very high tolerance, and it is very suitable therefore to reclaim the glass used as said purpose.
Glass and rock, cement etc. have essentially identical thermal capacity, so the glass heat-storing device of unit volume heat storage capacity with the heat-storing device of cement rock type under the identical condition of operating temperature is identical.At ambient temperature, rock type materials often has better capacity of heat transmission than glass.But the thermal conductivity factor of rock type materials descends with the rising of temperature, and the thermal conductivity factor of glass rises with the rising of temperature.When operating temperature vitreous heat accumulating more than 200 ℃ the time can reach and the equal or higher capacity of heat transmission of cement rock type materials.
Because glass and cement have quite approaching thermodynamic behaviour, the conductive fluid channel density in the glass thermal storage device can calculate with reference to the method for cement thermal storage device.Generally speaking, the ultimate range between the adjacent conductive fluid passage should not surpass 10cm, and optimum distance is about 3cm.The performance of the more little then thermal storage device of this distance is good more, and is also strong more to the fast-changing tolerance of conductive fluid temperature, but can increase the conductive fluid consumption.
Cause when reclaiming glass supply falls short of demand in the extensive utilization of solar energy, in order to reduce the consumption that reclaims glass, the heat storage brick also recovery glass of available fusing mixes and casts with a certain proportion of sandstone.Few and building stones such as granite that coefficient of thermal expansion and contraction is consistent with glass are good to the sandstone of selecting for use with the high hole of density, and the content ratio in heat storage brick generally should not surpass 70%, and the conductive fluid passage of heat-storing device is established two end points outlets, a cold junction and a hot junction.Conductive fluid is flowed to and flow by liquid pump control, and during store heat, the conductive fluid of coming from solar collector flows to cold junction from the hot junction.During the heat playback, conductive fluid flows to the hot junction from cold junction and flows to the hot equipment of using again.
The shortcoming of nature of glass heat accumulation equipment is relatively poor to the fast-changing tolerance of temperature, and variations in temperature is fast can break.In general, the temperature gradient of glass block inside should be limited within 30 ℃-40 ℃.As the way that solves, the control of the temperature of conductive fluid can realize by the Electronic Control to liquid road flow on the one hand; On the other hand, the zone of temperature difference maximum is the part at close cold and hot two ends in the heat-storing device.Therefore can better the minor diameter bead with resistance to sudden heating or diameter be no more than the cold and hot two ends near zone of 2 centimetres small-sized glass bar filling heat-storing device, as shown in Figure 2, can make heat-storing device to same end points conductive fluid in short-term the tolerance of variations in temperature bring up to more than 100 ℃, be enough to satisfy the general needs of using.It is worthy of note that the heat storage brick crack of some can not influence the performance of heat accumulation equipment.
A kind of manufacture method of solar energy heat storage device is characterized by: the manufacture method of described thermmal storage device may further comprise the steps: A, adopt and to aluminize or galvanized steel plain sheet carries out welding production and becomes metal shell; B, in metal shell with the tight filling heat accumulation of the mode that does not add bonding fragment of brick, and make between the adjacent heat accumulation fragment of brick communication passage that forms for the circulation of conductive fluid oil; C, respectively draw a metallic conduit at the upper and lower of metal shell and export as conductive fluid, the pipeline of metal shell top is the hot junction, and the pipeline of below is a cold junction; D, the space of respectively staying 5-15 to rise in the inner close exit, cold and hot two ends of metal shell, the bead of employing 5-20mm diameter or glass block filling; E, metal shell is sealed; F, at last that the outside of the metal shell of sealing is heat insulation with the thick glass fibre cotton of 20-30cm parcel forms the thermmal storage device.In the enforcement, the making of described heat accumulation fragment of brick may further comprise the steps: a, adopt clear water to clean after the variegated discarded glass that reclaims rejected impurity; B, the variegated discarded glass that will clean up are crushed to diameter less than 1 millimeter particle and fully mixing; C, the variegated discarded glass after will pulverizing is heated to 900 ℃-1100 ℃ and makes it fusing again; D, be at variegated discarded glass under the state of fusing and got rid of bubble in 5 to 15 minutes by stirring, the content that makes bubble is less than millesimal volume; E, will get rid of the variegated discarded glass that is in the state of fusing behind the bubble and pour into the heat storage brick die forming; F, be cooled to 500 ℃-700 ℃; G and then slowly cool to room temperature with 30 ℃-100 ℃ speed per hour.Adopt when making the heat accumulation fragment of brick on a large scale, the making of described heat accumulation fragment of brick may further comprise the steps: a, adopt clear water to clean after the variegated discarded glass that reclaims rejected impurity; B, the variegated discarded glass that will clean up are crushed to diameter less than 1 millimeter particle and fully mixing; C, the variegated discarded glass after will pulverizing is heated to 900 ℃-1100 ℃ and makes it fusing again; D, be at variegated discarded glass under the state of fusing by high temp glass liquid being placed the container of sealing, with air exhauster the air pressure in the container is reduced to below 100 millibars when stirring and gets rid of bubble, the content that makes bubble is less than millesimal volume; E, the variegated discarded glass that will get rid of the state that is in fusing behind the bubble cut out the bulk of required weight with milling train, be cooled to 650 ℃-750 ℃ after press forming; F, be cooled to 500 ℃-600 ℃; G and then slowly cool to room temperature with 30 ℃-100 ℃ speed per hour.When adding sandstone in the glass material of heat accumulation fragment of brick, glass material wherein is greater than 30%, and preferably glass material wherein is not less than 80%, and concrete preparation method is identical with the mixed step of above-mentioned pure variegated discarded glass c to g.
A concrete enforcement side example is pulverizing after the other substantially removal of impurity of variegated discarded glass of reclaiming, mixing, to be heated to 1000 ℃ again and to make it fusing.After stirring the eliminating bubble, pour into the heat storage brick die forming.Be cooled to after 600 ℃ and slowly cool to room temperature to avoid forming cooling stress per hour to be no more than 100 ℃ speed again.
When large-scale production, the molten glass about 850 ℃ can be cut out the bulk of required weight with milling train, be cooled to 700 ℃ after press forming.
The key of technology is the bubble in the glass metal that melts.The glass heat storage brick is much higher than general glass product to the tolerance of bubble, but too much bubble can form local stress in heat storage brick, reduces the ability to bear to thermal shock.Therefore the content of bubble should not surpass millesimal volume.And glass metal viscosity in the time of 1000 ℃ is higher, is unfavorable for the discharge of bubble, and the temperature that improves glass metal then obviously increases energy consumption and production cost.Except getting rid of the bubble by stirring, also high temp glass liquid can be poured in the container of sealing, when stirring, the air pressure in the container is reduced to below 100 millibars with air exhauster.This can make the bubble in the glass metal expand greatly, helps it to discharge outside the glass metal.
Under normal condition of work,, flow through the conduction oil temperature of device and the temperature difference of heat storage brick inside and just can remain in the positive and negative 50 ℃ scope as long as the power of heat accumulation and heat release is controlled at every cubic metre of heat-storage medium below 20 kilowatts.Because conduction oil is laminar flow in inner the flowing of device, and the thermal conductivity of conduction oil is far below glass, and the above-mentioned temperature difference is mainly absorbed by the conduction oil rete, so the thermograde in the bead is no more than 25 ℃, and the thermograde in the main heat storage brick is more less than 15 ℃.This has just guaranteed that heat-storing device can stably work over a long time.
