具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。同样，“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
移动式燃气轮机发电机组具有功率密度大、机动性强、使用方便等特点，可以快速到达现场提供电力，被广泛用于应急抢险和电网不发达地区的就地供电项目。本申请的发明人发现燃气轮机发电机组的输出功率受到环境温度和海拔高度的影响。温度越高、海拔越高，则发电功率越小。因此移动式燃机发电机组在高温或高海拔的环境中，最大功率低于其标准条件(15℃，0米海拔)下的功率，造成用电设备因供电不足而影响性能。另外，本申请的发明人还发现燃气轮机单循环发电效率约为35％，燃气轮机的排气以500℃ 左右的温度排向大气，没有得到利用。从能量转化效率来看，存在转化效率偏低的问题。
在固定式电站项目上，为解决燃气轮机出力不足，电效率偏低的问题，采用联合循环发电的模式。图1例示燃气蒸汽联合循环的示意图。如图1所示，燃气轮机发电机组1的排气热能在余热锅炉5中被回收以转化成高温高压蒸汽，高温高压蒸汽在蒸汽轮机2中做功发电，提升总电功率和综合效率。蒸汽轮机2中经做功发电的蒸汽通过凝汽器3经由冷却塔4冷凝，以循环回到余热锅炉5。然而，对于移动式燃机发电机组来说，设备的重量和尺寸都受到限制。蒸汽轮机2、凝汽器3、冷却塔4、余热锅炉5的尺寸和重量无法满足移动式设备的要求。当前燃气蒸汽联合循环设备的现有设计并不能集成在移动式发电设备中或者单独集成为移动式的燃气蒸汽联合循环设备。
本公开提供一种移动式余热回收发电装置，其使高温排气得到回收利用，转化成电能，并实现余热回收转化为电能的小型化移动设备设计。
图2例示根据本公开的实施例的移动式余热回收发电装置的示意图。
如图2所示，本公开的实施例的移动式余热回收发电装置包括：底盘6、进气组件7、膨胀发电模块8、蒸发器9、冷凝器10和散热器11。进气组件7、膨胀发电模块8、蒸发器9、冷凝器10和散热器11设置在底盘6上。
根据本公开的实施例，通过将进气组件、膨胀发电模块、蒸发器、冷凝器和散热器设置在底盘上，实现余热回收发电装置的撬装以实现移动式设计。
图3例示根据本公开的实施例的移动式余热回收发电装置的工作原理图，并且图4例示根据本公开的实施例的移动式余热回收发电装置的俯视框图。
如图3所示，进气组件7中设置有余热换热器71。如图2所示，蒸发器9和冷凝器10在垂直于底盘6的方向x上叠置，且如图4所示，蒸发器9和冷凝器10二者与膨胀发电模块8沿平行于底盘的第一方向z排列。例如，余热换热器71可以包括翅片管换热器。如图4所示，在平行于底盘6且垂直于第一方向z的第二方向y上，底盘6包括第一区域61、第二区域62和第三区域63。进气组件7设置在第一区域61，膨胀发电模块8、蒸发器9和冷凝器10设置在第二区域62，散热器11设置在第三区域63。例如，第一区域61、第二区域62和第三区域63在与第二方向y相反的方向上顺序设置。
根据本公开的实施例，将进气组件7设置在底盘6的第一区域61，膨胀发电模块8、蒸发器9和冷凝器10设置在底盘6的第二区域62，散热器11设置在底盘6的第三区域63，并且将膨胀发电模块8、蒸发器9和冷凝器10以模块化的方式进行叠置和平行排列设置，从而实现移动式余热回收发电装置的小型化设计。当然，可以根据移动式余热回收发电装置的各个分部的尺寸进行设置位置的调整。例如，也可以将膨胀发电模块8、蒸发器9和冷凝器10设置在第三区域63，将散热器11设置在第二区域62。本公开的实施例不限于此，只要实现移动式余热回收发电装置的撬装和小型化设计即可。
在一些实施例中，如图2和图4所示，蒸发器9和冷凝器10可以在垂直于底盘6的方向x上完全重叠，即，蒸发器9在底盘6上的正投影和冷凝器10在底盘6上的正投影完全重叠。
在一些实施例中，蒸发器9和冷凝器10可以在垂直于底盘6的方向x上部分重叠，即，蒸发器9在底盘6上的正投影和冷凝器10在底盘6上的正投影部分重叠(未示出)。
在一些实施例中，蒸发器9可以设置在冷凝器10的远离底盘6的一侧，如图2所示。
在一些实施例中，冷凝器10可以设置在蒸发器9的远离底盘6的一侧，(未示出)。
在一些实施例中，如图3所示，余热换热器71和蒸发器9中设置有形成闭合循环的第一管路12，第一管路中12设置有第一换热介质(未示出)，第一换热介质可以在闭合的第一管路12中循环。蒸发器9中除第一管路12之外的部分设置有工作介质(未示出)。蒸发器9的工作介质出口91与膨胀发电模块8的工作介质进口(未示出)连接。膨胀发电模块8的工作介质出口(未示出)与冷凝器10的工作介质进口101连接。冷凝器10和散热器11中设置有形成另一闭合循环的第二管路13。第二管路13中设置有第二换热介质(未示出)，冷凝器10中除第二管路13之外的部分设置有该工作介质。冷凝器10的工作介质出口102与蒸发器9的工作介质进口92连接。
根据本公开的实施例，膨胀发电模块8、蒸发器9和冷凝器10可以组成有机朗肯循环发电系统。
根据本公开的实施例，如图3所示，本公开的有机朗肯循环发电系统的基本工作原理如下。高温排气(例如，燃气轮机发电机组1的高温排气)导 入设置有余热换热器71(例如，包括翅片管换热器)的进气组件7，高温排气与余热换热器71的第一管路12中的第一介质进行换热，换热后的高温第一介质在第一管路12中输送至蒸发器9中，蒸发器9中的工作介质吸收高温第一介质的热量以吸热蒸发，被吸热换热后的第一介质在第一管路12中输送回到进气组件7中的余热换热器71。吸热蒸发的工作介质经由膨胀发电模块8的工作介质进口进入膨胀发电模块8，并在膨胀发电模块8中做功发电，做功后的工作介质经由膨胀发电模块8的工作介质出口和冷凝器10的工作介质进口101进入冷凝器10，且与冷凝器10的第二管路13中的第二介质进行换热以进行冷凝，吸收了冷凝释放的热量的第二介质输送至散热器11以使得冷凝释放的热量在散热器11中释放到环境中。冷凝后的工作介质经由冷凝器10的工作介质出口102和蒸发器9的工作介质进口92进入蒸发器9，这样完成余热回收发电的循环。
在一些实施例中，本公开的实施例的工作介质可以是有机介质，例如，R245fa。本公开的有机朗肯循环发电系统以有机介质作为工作介质，有机介质的沸点低且密度大。有机朗肯循环发电系统的工作介质由于沸点低，吸收的热源温度不超过350℃，而燃气轮机发电机组的排气(包括烟气)的温度高于500℃。因此，本公开的包括有机朗肯循环发电系统的移动式余热回收发电装置适用于燃气轮机发电机组或者其他适合的具有高温排气的设备。
在一些实施例中，第一换热介质包括导热油。导热油不易气化、性能稳定、导热效果好。
根据本公开的实施例，移动式余热回收发电装置采用导热油作为第一介质(用于例如来自燃气轮机发电机组的设备的高温排气和工作介质的中间换热介质)，解决了有机朗肯循环无法直接利用500℃高温排气(包括烟气)的问题。
根据本公开的实施例，设置有导热油的余热换热器可以回收60％以上的排气热能，并提供给有机朗肯循环使用。
在一些实施例中，第二介质可以包括冷却水。
在一些实施例中，散热器被模块化，以使得散热器的体积被减小且易于安装。例如，散热器包括多个平行设置的散热板。
根据本公开的实施例，通过模块化散热器、蒸发器、膨胀发电模块、冷凝器，解决了蒸汽朗肯循环发电设备复杂、体积重量超标的问题。
根据本公开的实施例，进气组件7具有换热和排气功能。例如，如图2所示，进气组件7可以设置有进气口73和排气口72，进气口73配置为导入高温排气(例如，燃气轮机发电机组的高温排气)，使得导入的高温排气与余热换热器71中的第一介质进行换热，与余热换热器换热后的排气从排气口72排出。
在一些实施例中，例如，排气口72可以设置在排气组件7的垂直于底盘6的部分上，即平行于方向x的部分上。这样有利于与第一介质换热后的高温排气从进气组件7中排放至外部环境。
在一些实施例中，例如，进气口73可以设置在排气组件7的平行于底盘6的部分上，即平行于方向y的部分上。这样有利于导入的高温排气与进气组件7中的第一管路12充分接触，从而与第一管路12中的第一介质充分换热。
在一些实施例中，如图2所示，散热器11和底盘6之间设置有泵组14。如图3所示，泵组14包括设置在第一管路12上的第一泵141。
根据本公开的实施例，第一泵为第一介质从蒸发器9输送至余热换热器71提供动力。第一介质与工作介质的换热温度可以通过调节第一泵141的流速来精确地控制，以避免蒸发器超温。
在一些实施例中，如图3所示，第二管路13上设置有第二泵142。第二泵为第二介质从冷凝器10输送至散热器11提供动力。第二介质与工作介质的换热温度可通过调节第二泵142的流速来控制。
在一些实施例中，如图3所示，蒸发器9的工作介质进口92和冷凝器10的工作介质出口102之间设置有第三管路19，第三管路19上设置有第三泵143。
根据本公开的实施例，第三泵143为工作介质从冷凝器10输送至蒸发器9提供动力。
在一些实施例中，泵组14还可以包括第二泵142和第三泵143。
在一些实施例中，如图2所示，底盘6设置在载重机构15上，载重结构15包括牵引部151。牵引部151设置在底盘6的一端。如图2和图4所示，第一区域61比第三区域63更远离牵引部151。
根据本公开的实施例，第一区域61比第三区域63更远离牵引部151，使得设置在第一区域61的进气组件7易于与具有高温排气的设备(例如，燃 气轮机发电机组)连接。
在一些实施例中，载重机构可以是载重汽车。
根据本公开的实施例，如图2和图4所示，第三区域63可以靠近牵引部151(例如，载重汽车的头部)，即，散热器可以设置为靠近牵引部151。
根据本公开的实施例，如图2和图4所示，第一区域61可以靠近载重机构的尾部(例如，载重汽车的尾部)，即，进气组件7可以设置为靠近载重机构的尾部，从而易于实现移动式余热回收发电装置与具有高温排气的设备(例如，燃气轮机发电机组)的快速连接。
在一些实施例中，如图2所示，底盘6在与设置有进气组件7、膨胀发电模块8、蒸发器9、冷凝器10和散热器11的一侧相反的一侧包括用于支撑和调节高度的部件16。
根据本公开的实施例，用于支撑和调节高度的部件16用于底盘6的刚性支撑和水平高度调节，以完成移动式余热回收发电装置的现场快速连接。例如，用于支撑和高度调节的部件16可以是解压撑腿。
在一些实施例中，进气组件7通过滑销导向机构(未示出)安装在底盘6上。
根据本公开的实施例，进气组件通过滑销导向机构安装在底盘上，实现其与燃气轮机发电机组或其他适合设备的高温排气口的对中。滑销导向机构包括膨胀节，从而补偿工作过程中进气组件由于导入高温排气引起的热膨胀。
用于有机朗肯循环发电的膨胀机包括螺杆膨胀机和涡轮膨胀机。涡轮膨胀机效率较高，但涡轮膨胀机功率越大，则体积尺寸越大，且多台小功率机组并列运行也影响载重机构上的空间布置。
本公开的实施例的膨胀发电模块8可以是包括涡轮膨胀机的涡轮膨胀发电模块。图5例示根据本公开的实施例的膨胀发电模块中的涡轮轮盘和发电机的示意图。如图5所示，该涡轮膨胀发电模块采用2组涡轮轮盘81和82对称布置的形式，2组涡轮轮盘81和82在发电机83的一侧驱动发电机83。该布置比单轮盘机组增加一倍的功率，并平衡了叶轮的轴向推力，有利于设备稳定运行。
根据本公开的实施例，移动式余热回收发电装置采用撬装化、模块化设计，以实现与适用的具有高温排气的设备的快速连接并将高温排气的热能转化为电能，提高了能源利用率。
图6例示根据本公开的实施例的燃气轮机发电设备的示意图。
本公开的实施例提供一种燃气轮机发电设备。如图6所示，该燃气轮机发电设备包括：根据本公开的实施例的上述移动式余热回收发电装置和燃气轮机发电机组1。燃气轮机发电机组1设置在另一底盘17上。移动式余热回收发电装置的进气组件7与燃气轮发电机组1的排气接口1001连接，以使来自燃气轮机发电机组1的高温排气(包括烟气)与进气组件7中的余热换热器71进行热交换。
根据本公开的实施例，利用移动式余热回收发电装置，使燃气轮机发电机组的高温排气得到回收利用，转化成电能，从而提升整体发电功率和能量转化效率。
在一些实施例中，如图6所示，另一底盘17设置在另一载重机构18上，另一载重机构18包括另一牵引部181，燃气轮机发电机组1的排气接口1001设置为远离另一牵引部181。
根据本公开的实施例，另一载重机构18可以是另一载重汽车，排气接口1001例如设置在该另一载重汽车的尾部。这样可以实现排气接口1001与移动式余热回收发电装置的进气组件7的快速对接。
燃气轮机发电机组的能量输出形式大概为：35％左右以电能输出，60％左右以高温排气散失到大气中，其余能量以机械损失、散热等形式输出。利用本公开的实施例的移动式余热回收发电装置，在有机朗肯循环发电系统的发电效率约为15～20％的情况下，燃气轮机发电机组的高温排气转化为电能的比例大于5.4％，其是这样计算出的：60％(燃气轮机发电机组的能量输出的60％为高温排气)×60％(余热换热器回收60％的排气热能)×15％(有机朗肯循环发电系统的发电效率为15％)＝5.4％。这样燃气轮机发电机组35％的发电转化率提升至少到40.4％，发电功率提升幅度大于15.4％。
不论移动式燃气轮机发电机组运行在标准环境状态下，还是运行在高温或高海拔条件下，本公开的移动式余热回收发电装置均大幅地增加了燃气轮机发电机组的电功率和电效率。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
