一种带盘管蓄冷器的液化空气储能系统
技术领域
本发明涉及液化空气的储能技术领域，具体涉及一种带盘管蓄冷器的液化空气储能系统。
背景技术
在能源供需矛盾日益突出的背景下，人们逐渐加大对绿色可再生能源如光能、风能和水能等领域的开发和利用。然而可再生能源具有随机性和间歇性等缺点，接入时会对电网产生冲击，甚至会引发大规模恶性事故。储能技术是实现可再生能源大规模接入、电力系统削峰填谷，以及分布式供能系统的关键技术，是目前实现可再生能源安全稳定的一个解决方案。液化空气储能不受场地限制，具有储能密度高和容量大等优点，是压缩空气能技术的发展趋势。
现有液化空气储能系统工艺主流程为，空气液化时，利用板式主盘管蓄冷器冷却压缩空气，冷量来自储存在蓄冷器的冷能介质；蓄冷时，冷能介质从液空汽化器获取冷量后传递给蓄冷器实现暂时储存。液化环节和蓄冷环节交替工作，实现一个周期内完整的传热循环。
目前的液化单元和蓄冷单元的工艺系统虽为成熟技术，但独立设置板式主换热和蓄冷器造成功能上的重复，且单元之间的联动操作较为复杂，冷能介质通过多次换热导致冷量损失很大，设备费用和占地面积都非常大。

所述空气加热膨胀及发电机构包括与汽化器12依次连接的加热器17和膨胀发电机单元14，膨胀发电机单元14出口端分三路，一路连接放空口16，一路连接冷却水系统，一路连接分子筛纯化系统15，液化空气从液空贮槽11经液空泵10加压并经过汽化器12蒸发后成为高压气态空气，高压空气通过膨胀发电机单元14入口前经加热器17加温后进行多级膨胀，膨胀发电机单元14通过输出轴带动发电机高速转动输出电能。
本发明的空气过滤器1为自洁式空气过滤器，所采用的蓄冷器8为盘管式蓄冷器，为了提高其畜冷效果，本发明采用若干台蓄冷器8并联或串联工作，用于满足冷却周期内的蓄冷和加热周期的换热要求，每台蓄冷器8的管道进出口设置温度探头和差压探头，蓄冷器8中部设有空气出口，所述空气出口通过管道连接膨胀增压机7，用于经蓄冷器8中部抽出部分空气去膨胀增压机7，冷却后进入气液分离器9；且蓄冷器8采用真空粉末绝热，外真空夹层充填珠光砂。

本发明实施例中的吸附器5为两台，且并联设置，所述吸附器5为两只切换使用，其中一只工作时，另一只再生，定时自动切换；保正交替连续工作。
实施例1 本发明实结合实施例具体阐释一种带盘管蓄冷器的液化空气储能系统流程工艺的原理。
常压原料空气经空气过滤器1除去灰尘和机械杂质后进入空气压缩机2加压至0.8Mpa，完成压缩后的105℃高温空气送入空气冷却塔3，由冷却水系统4中的冷却水槽402的水经冷却水泵404进入空气冷却塔3进行清洗，同时冷却水槽402中部分水进入水冷却塔401冷冻后通过冷冻水泵403进入空气冷却塔3对空气进行冷却，冷至20℃；
出空气冷却塔3的空气进入交替使用的吸附器5，空气中的二氧化碳、碳氢化合物和水分被吸附；净化后的空气进入膨胀增压机7的增压端增压至1.0Mpa，经膨胀增压机7的后冷却器冷却至常温后进入蓄冷器8；
进蓄冷器8的空气被分成两股，一股约30-40%的空气量从蓄冷器8中部抽出进入膨胀增压机7的膨胀端，预冷后-140℃的低温空气降至-170℃进入气液分离器9，另一股空气出蓄冷器8后经低温节流阀19至-172℃送入气液分离器9，进行分离，气液分离器9上部气体返回去蓄冷器8，冷凝后的液空输送至液空贮槽11中暂时储存，待膨胀发电14工作时，液空被液空泵10增压至10Mpa后得到高压常温气体输入汽化器12完成蒸发气化；
高压常温气体从汽化器12出来后经加热器17加温至120℃，再进入膨胀发电机单元14实现膨胀发电，为了充分利用输入系统的余热，每级膨胀机出口空气通过余热加热器18上的余热加温至120℃后再进入下一级膨胀机。
如图所示，本发明的膨胀发电机单元14工作时，蓄冷环节同时工作，所述冷媒介质选用0.7MPa的压缩空气。
循环风机13带动压缩空气实现闭式循环，常温空气获取气化器12低温液体蒸发冷量后冷却至-160℃得到低温空气，低温空气进入蓄冷器8将冷量传递给填料并暂时储存。
本实施例中蓄冷器8工作温度为-155℃，待下一个周期液化环节工作时，填料中的冷量被利用。
如图2所示，本发明的蓄冷器8工作流程如下：
液化系统工作时，第一阀门a、第二阀门b、第四阀门d、第五阀门e及第七阀门g处于打开状态，第三阀门c，第六阀门f处于关闭状态，压缩空气通过第一阀门a进入蓄冷器8被冷却，一股低温的中抽空气出第四阀门d进入膨胀增压机7，另一股低温空气通过第五阀门e去低温节流阀19。气液分离器9的低温回气通过第七阀门g去蓄冷器8回收冷量，常温回气从第二阀门b出去后作为吹扫气分两路，一路经加热器15后进入吸附器5，另一路经进入水冷却塔4。
如图所示，蓄冷系统或发电系统工作时，第三阀门c、第六阀门f处于打开状态，第一阀门a、第二阀门b、第四阀门d、第五阀门e及第七阀门g处于关闭状态，冷媒介质从汽化器12获取冷量后通过第六阀门f进入蓄冷器8储存冷量，常温冷媒由循环风机13驱动下从第三阀门c进入汽化器12，从而实现闭式循环。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
