Description

用于给近海设施内的内部空气除湿的方法和设置
技术领域
本发明涉及用于给近海设施内的内部空气除湿的方法和系统。
背景技术
近海设施，具体地近海风力涡轮，尤其由于盐和湿气而被侵蚀。具体地，盐由于其吸湿特性和在侵蚀反应中运载电子的自然能力是一个问题。
虽然近海设施的外侧必须被设计成承受各种因素的冲击，但是许多设施难以应对近海设施必须适应的严酷环境。具体地，在现代近海设施中必须有效地处理盐和水的组合侵蚀效果以便保证正常运行时间和生产效益。
盐和湿气将渗透到近海设施的内部，具体地通过设施的外部护罩内的漏隙而渗透，这样的漏隙是由于构造而造成或者是由于缺陷而造成。具体地来自于浪花和破碎浪的水滴或水雾的空气中盐分能够对近海设施内的敏感器械造成较大破坏。
在近海风力涡轮中，已知空气中盐分通过漏隙进入塔和机舱二者内，或者有时当外部空气被用于冷却内部零件时“非偶然地”进入。在一段时间之后，内部结构将被盐分层覆盖，这将吸引水并加速侵蚀。
侵蚀的速度主要由三个因素决定：1)相对湿度，2)盐度，和3)温度。其中相对湿度目前是最重要因素。
已经做出大量研究来描述近海环境中湿度和侵蚀速率之间的关联。大体而言，这些研究表明随着相对湿度减小，侵蚀速度减慢。在相对湿度为40-45％的情况下，不存在侵蚀，即使盐分存在仍如是。
同样ISO9223:2011指出该关系并且基于此将侵蚀分为六类，从无害的C1一直到非常严酷的海上环境C5X。
这种分类对于制造风力涡轮的成本是非常重要的。类别越高，则对于材料、表面处理等的要求就越多。因此，能够降低类别，具体地降低风力涡轮的内部的类别，将对风力涡轮的造价具有显著影响。
一种保护风力涡轮抵抗侵蚀的经济性方式是通过除湿器(例如干燥剂除湿器)来降低相对湿度。这样的系统是公知的并且已经被描述于多个专利申请中，例如WO2011/091863或者EP1736665。
吸附型除湿器(例如干燥剂除湿器)从穿过其的空气体积去除水。这个过程的核心是由特殊物质制造或涂覆的吸附型转子，其中该物质吸附构成经过空气中的湿气的水分子。由于转子吸附水，所以将必须去除被吸附的水以便恢复转子的吸附能力。为了去除转子内的湿气，转子被旋转到再生区域，在此它被加热空气干燥。温暖的潮湿的再生空气被导出，并且转子再次准备好吸收水分子。这种操作能够是连续的或者步进的。
图1描述了通常安装在近海风力涡轮中的除湿系统。在所述计划中，存在两个单独的空气流动，即处理空气(要被干燥的空气)和再生空气(用于从转子去除湿气的空气)。这是常规的所需计划；因为这样的计划对于空间是压力中性的并且对于近海风力涡轮应用也是期望的，不过其引入一个问题，即系统需要从外部引入再生空气。外部空气是含盐的，其具有包含盐分的水滴、气溶胶、雾气等。通常，非常难以适度地将盐分捕集在正常过滤器中，因为过滤器将变湿，并且含盐水将流过。在盐颗粒非常可能从其穿过的情况下，这降低了过滤器的效率。进一步，如果盐水被捕集，则盐将变粘，并且过滤器很可能被阻塞。
图2描述了通常安装在近海风力涡轮中被用于在涡轮塔中产生过压的除湿系统。除其他优点外，这还具有如下优点：减少通过例如塔和涡轮机舱内的漏隙的潮湿且侵蚀性空气的流入；冷却内部零件(齿轮、发电机、开关等等)。
在图2，外部空气被除湿并被吹入风力涡轮中。这将产生过压。在附图中，从外部但是也从内部获取再生空气，并且类似于正常压力设置，呈现的过压设置也由于盐分而具有过滤器低效和过滤器堵塞的问题。
EP1736665描述了一种使用除湿装置来干燥风能发电厂的内部空间的方法，其中该内部空间密封或至少基本密封以防空气交换，该除湿装置通过潮湿空气入口和干燥空气入口被连接到该内部空气且被设置在所述入口之间，其中通过将空气通过潮湿空气入口抽出内部空气，在内部空间内产生负压区域，并且通过经干燥空气出口将干燥空气排入到内部空间内，在内部空间内产生过压区域，并且在负压区域和过压区域之间在内部空间内形成干燥空气流动，并且通过空气管道使得潮湿空气入口和干燥空气出口保持距离彼此至少一定距离。
WO2011/091863描述了用于处理室内空气的系统，具体地用于处理风能发电厂的塔的内部空气内的室内空气的系统，其具有吸附型系统，其中干燥或被干燥供给空气从吸附型转子的至少一个除湿扇叶被传输到所述内部空间，并且借助于空气入口从所述空气外部向所述吸附型转子的至少一个再生扇叶供应潮湿且含盐的外部空气作为再生空气，并且其中经由空气出口向所述空气的外部释放被吸附在所述吸附型转子的除湿扇叶内的湿气，其特征在于：用于再生空气的热交换器，其具有彼此气密密封的空气管道，第一空气管道在进入侧被连接到所述空气入口并且在离开侧被连接到所述吸附型转子的所述再生扇叶，并且第二空气管道在进入侧被连接于所述除湿扇叶的所述出口和/或所述吸附型转子的所述再生扇叶的所述出口以及所述空气出口的离开侧和/或所述空间。
WO2011/091863还关注于在气流到达吸附型转子之前使用盐过滤器，其沿气流方向位于热交换器下游。
然而，外部盐分(即从风力涡轮外部进入除湿系统的盐分)的问题在于其处于潮湿环境并且因此难以被捕集。这导致盐分很可能穿过过滤器、减少安装的盐过滤器的使用寿命并且导致这种除湿器械的不希望的维修和停机时间，如本领域所描述的。
发明内容
因此本发明的目标在于，通过使得系统可用于且方法可用于给近海设施(具体地近海风力涡轮)内部除湿来改进现有技术，其中显著地提高了安装作为这种除湿系统的一部分的盐过滤器的效率和使用寿命，并且因此降低了用于维修这种近海设施的维修和停机成本。

具体实施方式
当被安装成用于给近海设施除湿的系统的一部分时本领域的盐过滤器的问题在于，由于过滤器的盐堵塞所造成的这种过滤器具有较短使用寿命并且具有降低的效率。
本发明通过构造上简单地改进了公知的除湿系统而克服了这种问题，从而增加了盐过滤器的效率和使用寿命，并且能够降低近海设施内的盐分扩散的总体风险，并能够降低具有带盐过滤器的被安装的除湿器的近海设施的维护时间和维修成本。
处理海上环境中的外部盐分的基本问题是关于盐的基于相对湿度的物理化学性质。根据相对湿度，盐的状态能够是干燥的、过饱和的或湿的。经常，同时在海上环境的空气中存在所有物相，其中过饱和和潮湿盐颗粒通常是主要的。
通常能够在适于要被处理的盐颗粒的尺寸的标准过滤器(通常是过滤器类别F8和更高类别)中处理干燥盐颗粒或具有干燥表面的盐颗粒。
过饱和且特别是潮湿的颗粒更易损坏过滤器。因为颗粒是湿的，所以盐将在过滤器上产生潮湿膜，从而增加盐不受阻地扩散通过过滤器的可能性，从而降低过滤器效率。进一步，它们更加易于阻塞过滤器。这会增加对这种盐过滤器的设计的要求并且可能导致不良过滤以及零件更换的高速率。
本发明建议实用在除湿器单元内生成的一些被除湿空气并且在空气供给到达盐过滤器之前使得这种被除湿空气再循环进入除湿器的空气供给内。通过使用较干燥的空气预处理空气供给，进入空气的相对湿度将在到达盐过滤器时已经被降低并且因此将减少盐颗粒处于过饱和或潮湿物理化学状态的可能性，从而有利于过滤器的盐颗粒和增加盐过滤器的使用寿命
技术人员将意识到，用于降低湿度的其他手段能够被应用到盐过滤器的空气供给以便在空气供给到达所述过滤器之前降低相对湿度，例如通过加热空气供给。不过，本发明已经发现，通过产生再循环流动，产生了用于近海目的的具体地易于处理的、低维护且具有能量效率的系统。
公开的是用于给近海设施2a，2b的内部除湿的设置1，该近海设施具体地是风能发电厂，所述内部被密封或至少基本密封以防与所述近海设施2a，2b的外部进行空气交换；所述除湿设置1包括用于允许空气从所述近海设施2a，2b的外部进入的空气入口4、盐过滤器11、除湿器单元12、引导所述进气空气从所述空气入口4经由所述盐过滤器11到达所述除湿器12的进气气流路径；从所述除湿器12导向所述近海设施2a，2b的内部的用于除盐且除湿空气的流动路径9；引导空气从所述内部经由所述除湿器12到达空气出口5的再生流动路径8b，其特征在于所述除湿设置1进一步包括被置于所述盐过滤器11上游的所述进气气流路径内的空气混合单元10；以及被设置成将所述除盐且除湿空气的流动的一部分从所述除湿器12引导到所述混合单元10的返回流动路径6；和/或将空气从所述内部引导到所述混合单元10的第一再循环流动路径。
在图3中示出了根据前一段落的根据本发明的示例性实施例，其中除湿器被公开成干燥剂旋转吸附单元的形式，并且其中除了上述公开的部件之外，还示出了空气过滤器14和加热器15作为再生流动路径8b的一部分，且该路径具有风扇13，16以用于移动空气穿过该设置。在这种示例性实施例中，空气离开除湿器12遵循单个流动路径7，并且在除湿器12和风扇13下游分流到流动路径6、8a和9。这种设置是优选的，但是本发明不限于此。例如对于一些应用而言，有利的是在引入风扇来移动空气之前较早地分裂流动路径。
图3中还公开并示出了，如上所述的设置进一步包括第二再循环流动路径8a，其被设置成将所述除盐且除湿空气的流动的一部分从所述除湿器12引导到所述再生流动路径8b。
离开除湿器12的空气将比进入空气更热，因为除湿和除盐过程会从系统释放一定量的存储能量。如果空气将被用于近海设施内部的冷却，则将想到，如上所述的设置能够通过使用热交换器被延伸，该热交换器例如板式热交换器或者简单地通过使用冷却器冷却。由于从内部空气去除了盐，所以不必要特制成用于近海使用的工业等级的冷却器仍然可以被用于该设置。
使用板式热交换器将需要使用外部空气来冷却，不过该外部空气不必要是无盐的，相反的，有利的是能够将热交换器设计成在系统维护时进行定期的整体单元的更换。
在这里在图4中公开并示出了如上所述的设置进一步包括热交换器17，其被设置在所述用于除盐且除湿空气的流动路径9内在所述除湿器12的下游。
在图4所示的本发明的示例性实施例中，经由流动路径9进入热交换器17的空气经由流动路径18离开热交换器，而冷却剂空气流动19借助于风扇20被传送通过热交换器。
在图5中也公开并示出了如上所述的设置进一步包括冷却器22，其被设置在所述用于除盐且除湿空气的流动路径9内在所述除湿器12的下游。
最后，公开了包括如上所述设置的除湿单元以及包括至少一个除湿单元的近海设施。
在进一步实施例中，除湿器单元12是干燥剂旋转吸附单元、冷能去单元或者加热单元。
进一步，混合单元10能够是具有用于混合空气流动的主动装置(例如风扇)的混合管道、混合室或者混合单元。同样，混合单元能够被构造成具有被动混合装置，例如通过被动螺旋钻。
如上所述的设置、除湿单元和近海设施提供多种优点，包括被过滤且除湿的空气提供了防侵蚀的手段、冷却或加热近海设施的手段以及根据需要供应新鲜空气和干净空气到近海设施中的进一步的设施和单元的手段。
图6示出了用于安装根据本发明的设施或单元的可能地点的示例性实施例。设施或单元被安装在距离海平面越远，则进气空气的含盐量越低。这对于一些应用是有益的，但是对于另一些应用优选地将设施或单元安装在近海设施内靠近海平面。对于一些应用而言，甚至有益的可能是将设置安装在近海设施外部，例如相邻工棚内，以便改善设置的可通达性以便维护。
权利要求中使用的术语“包括”不排除其他的元素或者步骤。权利要求中使用的术语“一”或“一个”不排除多个。权利要求中使用的附图标记不意味着限制范围。
虽然已经为了解释的目标具体描述了本发明，但是应该理解的是这些细节仅用于该目的，并且在不背离本发明范围的情况下本领域技术人员能够对其做出修改。
