Description
Technical field
The utility model relates to energy technology field, exactly is a kind of micro-crystalline ceramic electric heating energy-storage device.
Background technology
China is a country that energy supply is very nervous, also be the country of electric load maximum in the world, but it is very fast to exist the peak of power consumption load growth, and problem such as the network load rate descends year by year, and peak-valley difference is very big.
By peak clipping or peak load shifting new technology, peak requirements is suppressed to as far as possible minimum, or shift peak requirements to low-valley interval, effective utilization of the energy, the economical operation that reduces power plant input and electrical network all are beneficial to.According to Tokyo Electric Power's statistics, the every raising 1% of Japanese network load rate can reduce power supply cost 1%, reduces the C02 discharge capacity about 200～300KT, can also delay or postpone new unit construction, and potential economic benefit and social benefit are very huge.Since peak load shifting to economize on resources, energy-saving and emission-reduction are significant, so the electric heating energy-storage technology is important and effective technical means has obtained promotion and application widely in developed country as electrical network peak load shifting, energy-saving and emission-reduction one.But unhappy in China development, the reason of wherein existing national conditions and social macro policy aspect also has the reason of technical elements.
Electricity can not store, but can adopt multiple mode that the medium form is changed, and by the conversion of electric energy and other energy, plays the effect of " storage " electric energy indirectly, promptly adopts electrically heated mode that the energy storage material heating is also discharged when needed.
The main mode of electricity energy storage:
Early stage energy storage technology mainly is to adopt the storing material of water as energy, and as adopting the mode of ice cold-storage, water energy storage, along with the popularization of using, the later stage special energy storage material that begins one's study gradually mainly contains two big classes at present:
Latent heat storage material: i.e. phase-changing energy storage material, utilize electric energy to make material undergo phase transition (as the conversion between the solid-state liquid state) exactly, the thermal energy storage that absorbs during with phase transformation or discharge is got up, and discharges when needed.The phase-change material kind is a lot, can be divided into organic material and inorganic material two big classes again, in general, the stability of organic material and service life are not as inorganic material, domestic in practice be used for solar engineering or heat pump engineering auxiliary electrical heating project, design temperature are the following low temperature of 110 degree Celsius more; The subject matter of inorganic material be fusing back temperature very high, certain volatility is arranged, stronger to a lot of Corrosion of Metallic Materials, volume has certain variation before and after the fusing.
The sensible heat energy storage material: the thermal energy storage that absorbs or discharge when the material occurrence temperature is changed is got up, and the water reduction temperature as higher temperature need discharge heat energy to the external world, thereby reach the effect of rising ambient temperature.The sensible heat energy storage material adopts inorganic material more in the practice.
On the whole, it is lower that the energy storage density of sensible heat energy storage material and the phase-change material of hidden heat energy storage are compared energy storage density, thereby the product weight of being produced is big, volume is also huge, and then relative volume is little, in light weight to adopt the product of latent heat storage material.
Solve the problem of heating, energy storage and heat release simultaneously according to the characteristics of energy storage material as the energy storage product needed.What existing market can be seen is that three kinds of typical methods are arranged in the energy storage product the energy storage material except that adopting water: the one, and adopt metal alloy by special processing as energy storage material, ferrous alloy material for example, this method solves better energy storage, heat release problem technically, main production method is after the iron powder of certain granules degree and the inorganic-phase variable energy storage material of certain granules degree etc. are mixed by certain proportioning, through mould and forcing press extrusion forming, the blank with compression moulding forms through high temperature sintering again.Be characterized in that iron powder is after high temperature melting is cooled off again, form the spongy skeleton of class of an irony, skeleton surface and the inner less honeycomb hole of size one by one that forms, hole contains the energy storage phase-change material, phase-change material energy storage fusing back is fixed in the hole because of capillary effect, the skeleton of irony plays the effect of heat conduction simultaneously, during heating heat is conducted to energy storage material, again heat is conducted out during heat release.This method preferably resolves the heating and the heat release problem of energy storage material, but the weight of this product is bigger, there is the corrosion problem in iron frame, its process is very big to the pollution of environment, do not meet environmental protection requirement, adopt the method for infrared heating simultaneously, the life-span of heater has only 3000 hours, life-span is shorter, and the efficient of heating is relative with speed not high.Another kind of typical method is that organic phase change energy storage material is enclosed in the small containers, make energy storage capsule, energy storage ball, energy storage post or energy storage plate, the small containers that energy storage material will be housed again places in the bigger container makes the energy storage case, this method adopts low-temperature phase-change material more, by water (the employing conduction oil is also arranged) as heat-conducting medium, by thermal source independently heat-conducting medium is heated during energy storage, by heat-conducting medium heat is conducted to energy storage material, heat-conducting medium conducts out with the heat in the energy storage material again during heat release again.This method cost is higher, and, energy storage capacity relatively poor relatively because of the stability of organic phase change material decays very fast.Also have a kind of method that adopts the sensible heat energy storage in the market, this method is to use the inoganic solids energy storage material, and the inoganic solids energy storage material is made the block of certain specification and size, in manufacturing process heating wire or electrothermal tube directly is embedded in the solid material.This method cost is minimum, and certain application is also arranged in the practice, but service life is short, and reliability, technology and quality are the poorest.
Simultaneously, go back the problem that ubiquity adopts the low-voltage heating in the product of on electric heating energy-storage market, having promoted at present, limited the promotion and application of electric heating energy-storage project.Be existing phase-changing energy storage material is not all considered proof voltage in design process problem on the one hand, the for example special metal alloy energy storage material of developing, the proof voltage of organic phase change material is lower, the very low or conduction of inorganic phase-changing material proof voltage level under molten condition makes its energy storage device can't adopt the high voltage mode of heating.Many non-phase-changing energy storage materials, as inoganic solids class energy storage material proof voltage level is higher but its energy storage density is very low, make product after weight too heavy, bulky.Be that China's commercial and residential building, residential quarter and industrial enterprise on a large scale etc. generally all adopt the 10KV high voltage supply on the other hand, but after circuit arrives the user, how can become 380v or 220v low-voltage to use, the power supply heating that the equal basically working voltage of therefore present energy storage electric calorifie installation is 380V or 220V through device translates such as low voltage distribution transformers for other electrical equipment.But, electric heating energy-storage need be in 6-8 hour low-valley interval, the thermal energy storage that whole day needs is got up, just need bigger electrical power, most users' low-voltage distribution apparatus (as transformer) finite capacity, if present electric heating energy-storage device is installed, the user usually needs to change existing part or a complete set of power supply unit, comprise transformer, switch cubicle, switch board and circuit etc., usually cause bigger extraneous expense.Therefore, the low-voltage mode of heating has caused restriction to promoting the use of of electric heating energy-storage project, has formed a kind of bottleneck, has limited the development of electric heating energy-storage project.
For addressing the above problem, the inventor had once proposed a kind of " the nanometer electrical heating energy storage device that can be used for high voltage source ", and finding in the practice still has the improved necessity of continuation.
Micro-crystalline ceramic is the new ceramic material that grew up in recent years, because the micro-crystalline ceramic material has good mechanics, electricity, magnetics, performances such as optics, as the mechanical strength height, wear resistant corrosion resistant, good in oxidation resistance, insulating property (properties) is good, the coefficient of expansion is adjustable, Heat stability is good etc., particularly its shaking property of heat resistanceheat resistant and corrosion resistance of possessing simultaneously is that other materials is not available, and simple fabricating technology, cheap raw material and low manufacturing cost, and the advantage of energy large-scale industrialization production, a kind of high-performance low price of can yet be regarded as, the new ceramic material that application market is wide, become one of focus of new ceramic material Application and Development, opened up a uncharted field that does not have substitution material can satisfy its specification requirement, thereby obtained in a lot of fields to use widely.
