下面结合附图对本发明的蓄热调峰发电装置作进一步详细说明。
附图说明
图1为本发明的蓄热调峰发电装置的结构示意图的主视图。
具体实施方式
如图1所示，本发明的蓄热调峰发电装置，包括保温壳体1，保温壳体1内设有气体通道2，气体通道2内设有导电材料制成的蓄热体3，蓄热体3的二端通过电气控制装置与电源 相连，蓄热体3用于将外界输入的电能转换为热能并储存起来，蓄热体3的周围设有可让气流通过的换热空间，气体通道2的出气口与涡轮机4的进口相通，涡轮机4的动力输出轴与发电机11的动力输入轴传动相连，涡轮机4的出口与可冷却气体的冷却器8或余热锅炉的进气口相通，冷却器8或余热锅炉用于冷却流动穿过其内部冷却通道的气体，冷却器8或余热锅炉的出气口与压气机7的进口相通，压气机7的出口与气体通道2的进气口相通，气体通道2、冷却器8或余热锅炉、涡轮机4和压气机7构成一个布雷顿循环系统，气体通道2、冷却器8或余热锅炉、涡轮机4和压气机7内充有用于循环的气态的工质。
为了高效率的使用本发明的蓄热调峰发电装置，避免无谓的能源浪费，当涡轮机4的动力输出轴驱动发电机11的动力输入轴转动并发电时，蓄热体3在电气控制装置的调控下停止将电能转换为热能，当蓄热体3在电气控制装置的调控下将电能转换为热能时，涡轮机4的动力输出轴不得驱动发电机11的动力输入轴转动并发电。
作为本发明的进一步改进，上述气体通道2内自前向后设有多个蓄热体3，每个蓄热体3的二端通过电气控制装置与电源相连，位于每个蓄热体3附近的气体通道2侧壁上都分别设有气体通道2的出气口，每个气体通道2的出气口处分别设有气体流量调节装置5，每个气体通道2的出气口都通过输气通道6与涡轮机4的进口相通。在使用时，可通过调节开启不同数量的气体流量调节装置5，或者开启不同位置气体流量调节装置5来调节气态工质的温度和流量，进而也调节了发电机11的发电量。例如，只开启位于气体通道2的进气口端的气体流量调节装置5，则输送到涡轮机4的工质的流量和工质的温度都会相对较低，如果增加开启位于气体通道2的进气口段的气体流量调节装置5，则输送到涡轮机4的工质的流量和工质的温度都会相对提高。反之，开启位于气体通道2的出气口端的气体流量调节装置5，则输送到涡轮机4的工质的流量相对较低，但工质的温度都会相对较高，如果增加开启位于气体通道2的出气口段的气体流量调节装置5，则输送到涡轮机4的工质的流量会增加，而工质的温度会相对降低。这样就可以灵活的调节发电机11的发电量，以适应不同的用电量变化。

作为本发明的进一步改进，上述压气机7的出口与涡轮机4的进口通过调温气道9相通，调温气道9上设有调节气体流量的截门10。
作为本发明的进一步改进，上述气体通道2、冷却器8或余热锅炉、涡轮机4和压气机7内循环的工质为氢气或氦气或氮气或氩气或二氧化碳。
作为本发明的进一步改进，上述余热锅炉8可利用穿过其内部的工质所携带的热量生产热水或蒸汽。
为了让蓄热体3能够储存足够多的热能，蓄热体3的熔点通常要高于1400℃，蓄热体3储热时的上限温度可以设定在1400℃附近，对于圆形截面的蓄热体3，蓄热体3的截面尺寸可以设置成直径100mm—300mm，总长度大于1000米，从而能够储存足够多的热能。
本发明的蓄热调峰发电装置在使用时，其蓄热体3的二端通过电气控制装置与电源相连，蓄热体3用于将外界输入的电能转换为热能并储存起来，因此本发明用于将各种水电、太阳能发电装置、风能发电装置在发电高峰产生的电能转换成热能储存起来，而在用电高峰时，由于气体通道2、冷却器8或余热锅炉、涡轮机4和压气机7内充有用于循环的气态的工质，启动压气机7，气态的工质就会升压并注入气体通道2的进气口，然后气态的工质会沿着气体通道2流动并被蓄热体3加热，被加热的气态的工质会进入涡轮机4并驱动涡轮机4转动，然后涡轮机4会拖动发电机11转动并发电，由此将用电高峰将储存的热能快速、高效率地转化成电能；发电后从涡轮机4排出的气态的工质会进入冷却器8或余热锅炉，在此气态的工质会被降温，然后再从冷却器8或余热锅炉排出，然后气态的工质会再次回到压气机7，重新被加压后再次进入气体通道2内，如此循环往复，就可以逐渐将蓄热体3储存的热能再次转换为电能。因此，本发明的蓄热调峰发电装置可以高效率的将各种水电、太阳能发电装置、风能发电装置在发电高峰产生的电能转换成热能储存起来，然后在用电高峰将储存的热能快速、高效率地转化成电能，让现有的各种水电、太阳能发电装置、风能发电装置的利用效率更高，避免大量的水电、太阳能、风能地发电能力浪费的热能。
