Description

中温蓄热材料、 蓄热元件及由蓄热元件构成的供热装置 技术领域  Medium temperature heat storage material, heat storage element and heat supply device composed of heat storage element
本发明涉及一种热交换领域,具術步及一种用于进行热交换之中温蓄热材料、 包含有蓄热材料之蓄热元件的结构以及由该蓄热元件构成的蓄能供热装置。  The present invention relates to a field of heat exchange, a step and a structure for performing heat exchange of a medium temperature heat storage material, a heat storage element including the heat storage material, and an energy storage heat supply device comprising the heat storage element .
背景技术 Background technique
目前, 能源紧张已经制约了经济发展和人民生活水平的提高, 煤荒、 电荒、 气荒给哦们敲响了能源警钟, 节约一次能源, 发展使用可再生能源、 余热废热的 回收和合理利用至关重要。 我国电力工业近几年发展迅速, 但电力供应紧张状况 并没有得到根本改观, 主要表现在: 电网负荷率低, 系统峰谷差距大, 城市生活、 商业用电快速增长, 工业用电比重相对减少。 这种实况促进了能源综合利用技术 的发展, 而中温蓄能供热技术是其最关键技术之一。  At present, energy shortages have constrained economic development and the improvement of people's living standards. Coal shortages, power shortages, and gas shortages have sounded energy alarms, saved primary energy, developed the use of renewable energy, and recovered and utilized waste heat. It is vital. China's power industry has developed rapidly in recent years, but the power supply tension has not been fundamentally improved. The main performances are: low grid load rate, large system peak-to-valley gap, rapid growth of urban life and commercial electricity consumption, and relative reduction of industrial electricity consumption. . This kind of reality promotes the development of comprehensive energy utilization technologies, and medium-temperature energy storage heating technology is one of its most critical technologies.
目前被普遍采用的蓄热技术主要有: 常压水蓄热和高温水蓄热、 固相高温蓄 热。 由于水在 0°C时的溶解潜热(80cal/g)和 10CTC时的汽化潜热(539cal/g) 等相变潜热都较大, 但容积密度 (lg/ml)和比热(lcal/g. °C )较小, 所以水的 潜热、 显热蓄热密度小, 用水做介质蓄热都是利用显热特性: 常压水蓄热和高温 水蓄热技术是利用水的温差显热特性, 蓄热密度小, 蒸汽蓄热是利用水的汽化潜 热, 虽然汽化热大,但蒸汽密度小,压力高, 故相对蓄热密度小; 词相高温蓄热是 用电加热管将固态成型材料加热到 400- 700°C, 再通过高温换热蒋蓄存的热量释 放出去, 其换热装置复杂、 压力高、 安全性能差, 保温难度大, 热损失大。  At present, the commonly used regenerative technologies are: atmospheric pressure water storage and high temperature water storage, solid phase high temperature storage. Due to the latent heat of decomposition (80 cal/g) of water at 0 °C and latent heat of vaporization (539 cal/g) at 10 CTC, the bulk density (lg/ml) and specific heat (lcal/g. °C) is small, so the latent heat of the water and the sensible heat storage density are small. The use of water for medium heat storage utilizes sensible heat characteristics: Atmospheric pressure water storage and high temperature water heat storage technology utilizes the temperature difference sensible heat characteristics of water. The heat storage density is small. The steam heat storage uses the latent heat of vaporization of water. Although the heat of vaporization is large, the steam density is small and the pressure is high, so the relative heat storage density is small. The word phase high temperature heat storage is to heat the solid molding material with an electric heating tube. By 400-700 °C, the heat stored in the high-temperature heat exchange is released, and the heat exchange device is complicated, the pressure is high, the safety performance is poor, the heat preservation is difficult, and the heat loss is large.

本发明根据上述蓄热材料设计了一蓄热元件 4, 如图 3所示, 它主要包括二 可传热之壳体 41和强化传热片 43, 所述壳体 41为金属筒状体, 一端先用封堵片 42封闭,可通过焊接实现,筒状体内腔装设一强化导热片 43, 中温相变蓄热材料 6充满于壳体 41内腔, 可填满强化导热片 43与壳体 41内壁之间的所有间隙, '使 整个壳体 41成为一带有相变材料的蓄热元件 4,相变蓄热材料 6充满后将壳体 41 另一端亦用封堵片 2封闭。所述强化导热片 43的设置主要是因为相变蓄热材料 6本身为一可进行液、 固转换的材料, 而壳体 41内腔中心位置相对内壁之传热滞 后, 会影响晶体结晶速度, 进而影响蓄热元件的蓄热和放热效果, 将强化导热片 43设置于相变蓄热材料 6之间, 可加快热的传播速度, 保证其相变蓄热材料 6处 于壳体 41内腔不同的位置时,蓄热、放热速度的一致。 同时, 为保证传热速度的 均匀,所述强化传热片 43 用金属片制成麻花状结构,这种结构可一次加工^ 型, 且相通重量的材料其表面积最大, 因而其传热面也较大, 传热效果最好。 更正页(细则第 91条) 在壳体 41上, 还加工有至少一个非对称的散热导流环 45, 可在壳体 41之筒 状加工时一次成形。 这种结构设计加工时非常容易, 且成本也很低, 既可增加壳 体 41内壁之强度,延长蓄热元件 4 寿命, 又可提高同等重量份壳体 1之外表 面积, 以提高蓄热元件 之传热面积, 加快蓄热相变材料 6的蓄热和放热速度, 还可使其在处于导热介质中起导流作用, 在多个蓄热元件 叠放时提高相互之间 的间隙, 进一步提高传热效果。 另外, 也可起支撑作用, 便于搬运时的置放。 ' 本发明蓄热元件 4的工作原理和工作流程是: According to the present invention, a heat storage element 4 is designed according to the above heat storage material. As shown in FIG. 3, it mainly comprises two heat transferable housings 41 and a reinforced heat transfer sheet 43, and the housing 41 is a metal cylindrical body. One end is first closed by the sealing piece 42 and can be realized by welding. The cylindrical inner cavity is provided with a reinforcing heat conducting sheet 43, and the medium temperature phase change heat storage material 6 is filled in the inner cavity of the casing 41, and can fill the reinforcing heat conducting sheet 43 and the shell. All the gaps between the inner walls of the body 41 make the entire casing 41 a heat storage element 4 with a phase change material. After the phase change heat storage material 6 is filled, the other end of the casing 41 is also closed by the sealing sheet 2. The arrangement of the reinforcing thermally conductive sheet 43 is mainly because the phase change heat storage material 6 itself is a material capable of liquid-solid conversion, and the heat transfer hysteresis of the inner position of the inner cavity of the casing 41 relative to the inner wall affects the crystal crystallization speed. Further, the heat storage and heat release effects of the heat storage element are affected, and the reinforcing heat conductive sheet 43 is disposed between the phase change heat storage materials 6, so that the heat propagation speed can be accelerated, and the phase change heat storage material 6 is ensured to be in the cavity of the casing 41. When stored in different positions, the heat storage and heat release rates are the same. At the same time, in order to ensure uniform heat transfer rate, the reinforced heat transfer sheet 43 is made of a metal sheet into a twist-like structure, and the structure can be processed at one time, and the material of the weight-matching material has the largest surface area, and thus the heat transfer surface thereof is also Larger, the best heat transfer effect. Correction page (Article 91) At least one asymmetric heat dissipating ring 45 is also machined on the housing 41 for one time forming during the cylindrical processing of the housing 41. The structure design is very easy to process and the cost is also low, which can increase the strength of the inner wall of the casing 41, prolong the life of the heat storage element 4, and increase the surface area of the casing 1 of the same weight to improve the heat storage element. The heat transfer area accelerates the heat storage and heat release rate of the heat storage phase change material 6, and can also cause a flow guiding action in the heat conductive medium to increase the gap between the plurality of heat storage elements when stacked. Further improve the heat transfer effect. In addition, it can also serve as a support for easy placement during handling.

Material 6, the temperature of the phase change heat storage material 6 is increased by the recommended weight, and the sensible heat is stored. When the temperature reaches the melting point (7 9 Ό), the phase change heat storage material 6 begins to melt, stores the latent heat, and all melts and reaches When the external heat transfer medium is at the same temperature, the heat storage process ends; when the temperature of the heat transfer medium is lower than the temperature of the phase change heat storage material 6, the phase change heat storage material 4 will pass through the metal cylinder case 41 and the plugging piece 42 and the reinforcing heat conductive sheet. 43 uniformly guides the heat medium to release heat, and the temperature gradually decreases. When the melting point (79 °C) is reached, the solidification begins and the latent heat is released. Below the melting point (79 °C), the latent heat of phase change is completely released, and the temperature continues. The lowering of the heat release process begins after the sensible heat is released and reaches the same temperature as the external heat transfer medium.
