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，下面将结合本公开实施例的附图，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。“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。
本公开至少一实施例提供一种油气处理系统，该油气处理系统包括油气分离装置和第一油气输送装置。油气分离装置配置为对油气产生装置产生的油气进行油气分离处理，油气分离装置包括润滑油箱，用于容纳润滑油；第一油气输送装置与润滑油箱连通，且配置为将油气至少部分输送至润滑油箱内，润滑油箱配置为对输送到润滑油箱内的油气进行分离，分离出来的油产物留在所述润滑油箱内。
下面，结合附图对本公开实施例提供的进行详细的说明。
图1为本公开一实施例提供的一种油气处理系统的示意图。如图1所示，油气处理系统10包括油气分离装置，油气分离装置配置为对油气产生装置产生的油气进行油气分离处理。油气分离装置包括润滑油箱1，润滑油箱1用于容纳润滑油。油气处理系统10还包括第一油气输送装置2；第一油气输送装置2与润滑油箱1连通，且配置为将油气至少部分输送至润滑油箱1内，润滑油箱1配置为对输送到润滑油箱1内的油气进行分离，分离出来的油产物留在润滑油箱1内。在油气产生装置中，由于需要对多个零部件进行润滑，因此需要配备润滑系统，润滑系统包括至少一个润滑油箱。如此，本公开实施例提供的油气处理系统利用润滑油箱对油气产生装置产生的油气进行油气分离，易于操作，不需要另外设置油气分离装置，简化了油气处理系统的结构，且节约成本。
例如，油气产生装置包括内燃机，例如包括发动机，发动机包括燃烧室，燃料在燃烧室燃烧以为发动机的运行提供动力，从而，由于燃料燃烧而在燃烧室内产生大量油气(油雾)，该油气包括气体和悬浮在其中的细小油滴。需要说明的是，在本公开实施例中，油气产生装置不是润滑油箱。
如图1所示，例如，润滑油箱1内置有润滑油7，并且第一油气输送装置2配置为将所述油气喷射至所述润滑油7的液面70上，从而，油气中的细小油滴会聚集、沉降至润滑油7中，从而实现油气分离。例如第一油气输送装置2包括油气输送管道。
例如，如图1所示，第一油气输送装置2的出口201位于所述润滑油箱1内且与所述润滑油间隔开，以避免将油气直接通入润滑油中而增加油气中的油含量，如此，更加利于提高油气分离的效果。
例如，第一油气输送装置2包括第一管道，第一油气输送装置2还可以包括其他与第一管道配合的用于输送油气的结构，可参考本领域常规技术，本申请对此不作限定。
例如，如图1所示，第一油气输送装置的出口201具有楔形的开口，所述楔形的开口朝向所述润滑油7的液面70，所述油气通过所述楔形的开口喷射至所述润滑油箱1内。该楔形的开口利于增大油气的出射面积，提高油气分离效率。
例如，如图1所示，油气处理系统10还包括网格结构5，网格结构5位于楔形的开口处且包括多个网孔，配置为使所述油气从所述第一油气输送装置经所述多个网孔喷射至所述润滑油7的液面70，网格结构5可将油雾进一步的分离。例如，如图1所示，网孔的形状包括矩形；在一些实施例中，网孔的形状可以包括圆形，如图2所示；在一些实施例中，网孔的形状也可以包括菱形、不规则图形等，本公开实施例对此不作限定。
例如，油气从油气产生装置经第一油气输送装置2被直接通入润滑油箱1内，即油气从油气产生装置排出后除了经过第一油气输送装置2之外，不经过任何其他的结构，被通入润滑油箱1内，例如从涡轮发动机的燃烧室排出的油气经第一油气输送装置2被直接通入润滑油箱1内。如此，润滑油箱1作为第一级油气分离装置，基本上所有的油气均可被通入润滑油箱1内，可以以便捷、低成本的方式处理大量的油气。
例如，油气处理系统还包括气体排放管道3，气体排放管道3与润滑油箱1连通且与大气连通；润滑油箱1的气体产物通过气体排放管道3排入大气。例如，气体排放管道3中设置有过滤器4，气体排放管道3中的气体经 过滤器4过滤之后进入大气，过滤器中含有可吸附油滴、去除二氧化硫等空气污染物的物质，以进一步降低润滑油箱1的气体产物中的油含量以及减少或去除润滑油箱1的气体产物中的二氧化硫等空气污染物，保证进入大气的气体质量，降低从润滑油箱1排出的气体对大气的污染。
图2为本公开一实施例提供的另一种油气处理系统的示意图。图2所示的实施例与图1所示的实施例的区别在于，第一油气输送装置2的出口201位于所述润滑油箱1内且与所述润滑油间隔开且正对润滑油7的液面70，以使油气中的大量微小油滴在液面70上撞击，更迅速地聚集和液化，从而提高油气分离效率。例如，在一些实施例中，出口201包括楔形的开口，楔形的开口朝向润滑油的液面70。当然，在一些实施例中，出口201的截面的形状不是楔形。例如，第一油气输送装置2的出口201与润滑油70的液面之间的距离小于等于10cm，该距离较小有利于提高油气中的大量微小油滴在液面上液化速度，进一步提高油气分离的效率和效果。图2所示的油气处理系统的其他特征和技术效果均与图1中的相同，请参考之前的描述。
图3为本公开一实施例提供的另一种油气处理系统的示意图。图3所示的实施例与图1所示的实施例的区别在于，润滑油箱1内设置有阻挡结构6，并且所述第一油气输送装置2配置为将所述油气喷射至所述阻挡结构6上，如此，相比于喷射至空腔的空气中，能够增加更加油气中的微小的油滴的撞击，利于油气中的微小的油滴的聚集，从而利于微小的油滴的液化。例如，阻挡结构6设置于润滑油箱1的箱体壁上，例如在本实施例中，阻挡结构6设置于与润滑油7的液面70相对的上箱体壁上。楔形的开口201有利于引导油气喷向阻挡结构6。例如，第一油气输送装置2的输出端的管道是竖直的，阻挡结构6是倾斜的，其与第一油气输送装置2的输出端的管道相交；例如阻挡结构6的面向楔形的开口201的表面与楔形的开口201所在的面平行；例如，第一油气输送装置2的出口正对阻挡结构6。图3所示的油气处理系统的其他特征和技术效果均与图1中的相同，请参考之前的描述。
图4为本公开一实施例提供的另一种油气处理系统的示意图。图4所示的实施例与图3所示的实施例的区别在于，阻挡结构6的设置方式不同。如图4所示，例如，阻挡结构6设置于润滑油箱1的下底壁上，设置于润滑油 箱1的被润滑油覆盖的下底壁上。例如，阻挡结构6设置于润滑油箱1的被润滑油覆盖的下底壁上，阻挡结构6的一部分浸没于润滑油中。第一油气输送装置2配置为将所述油气喷射至所述阻挡结构6上。例如，第一油气输送装置2的输出端的管道是倾斜的，阻挡结构6垂直于润滑油箱1的下底壁。例如，阻挡结构6的面向楔形的开口201的表面与楔形的开口201所在的面平行，从而，楔形的开口201有利于引导油气喷向阻挡结构6。图4所示的油气处理系统的其他特征和技术效果均与图3中的相同，请参考之前的描述。
图5为本公开一实施例提供的另一种油气处理系统的示意图。图5所示的实施例与图1所示的实施例的区别在于，第一油气输送装置2配置为将所述油气喷射至所述润滑油箱1的内壁101上。如此，相比于喷射至空腔的空气中，能够增加更加油气中的微小的油滴的撞击，利于油气中的微小的油滴的聚集，从而利于微小的油滴的液化。例如，出口201包括楔形的开口，楔形的开口朝向润滑油箱1的内壁101。例如，第一油气输送装置2的出口正对润滑油箱1的内壁101，即楔形的开口正对润滑油箱1的内壁。图3所示的油气处理系统的其他特征和技术效果均与图1中的相同，请参考之前的描述。
图6为本公开一实施例提供的另一种油气处理系统的示意图。图6所示的实施例与图1所示的实施例的区别在于，第一油气输送装置2包括多个输出管道，油气通过多个输出管道进入润滑油箱1中。例如，第一油气输送装置2包括第一输出管道21和第二输出管道22；第一输出管道21包括第一出口201，第二输出管道22包括第二出口202；第一出口201朝向润滑油箱1的内壁，第一输出管道21配置为将油气喷射至润滑油箱1的内壁上；第二出口202朝向润滑油7的液面70，第一输出管道21配置为将油气喷射至润滑油的液面上。如此，可增大油气分离的处理效率，获得多种喷射油气的方式的技术效果的叠加，得到更好地油气分离效果。图3所示的油气处理系统的其他特征和技术效果均与图1中的相同，请参考之前的描述。
例如，在一些实施例中，油气分离装置包括多个级联的子油气分离装置，每级子油气分离装置对所述油气进行油气分离处理，上述润滑油箱作为所述多个级联的子油气分离装置之一。例如，油气分离装置还包括输油装置，输 油装置配置为将多个级联的子油气分离装置当中除所述润滑油箱之外的子油气分离装置分离出来的油产物输送至所述润滑油箱中。
例如，多个级联的子油气分离装置当中除润滑油箱之外的子油气分离装置包括冷凝装置，冷凝装置配置为对油气进行冷凝处理以使油气中的油液化。
示例性地，图7为本公开一实施例提供的又一种油气处理系统的示意图。如图7所示，多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置包括冷凝装置82，油气产生装置产生的油气通过第二油气输送装置821输入冷凝装置82。例如第二油气输送装置821包括油气输送管道。冷凝装置82对油气进行冷凝处理以使油气中的油液化，经冷凝装置82对油气处理后的气体产物通过第一油气输送装置2进入润滑油箱1中以进行下一级油气分离，经冷凝装置82对油气处理后的油产物通过输油装置9输送至润滑油箱1中，以回收利用，以用作对油雾产生装置等设备的润滑油。如此，冷凝装置82与润滑油箱构成两级级联的子油气分离装置。图7中的润滑油箱1进行油气分离的方式如之前的实施例中所述，在此不再赘述。
例如，如图7所示，输油装置9的出口与所述润滑油箱1连接，并且所述输油装置9的出口位于所述润滑油箱1中的润滑油7的液面70以下，即，位于液面70的远离润滑油7上方的空间的一侧。以避免对润滑油箱1中的油气分离的气体产物中的油含量造成影响。
例如，如图7所示，油气处理系统10包括气体排放管道3、油量检测模块11、第一阀门121、油气返回管道30和控制模块。气体排放管道3与所述多个级联的子油气分离装置中的最后一级子油气分离装置连通且与大气连通，在本实施例中，最后一级子油气分离装置为润滑油箱1。油量检测模块11配置为检测所述气体排放管道3中的气体的油含量；第一阀门121位于所述气体排放管道3内；例如，油气返回管道30连通所述最后一级子油气分离装置即润滑油箱1与冷凝装置82。控制模块配置为：若气体排放管道3中的气体的油含量小于等于标准值，控制第一阀门121打开以将最后一级油气分离装置即润滑油箱1的气体产物通过气体排放管道3排入大气，且配置为：若气体排放管道3中的气体的油含量大于所述标准值，控制第一阀门121关闭，且控制位于油气返回管道30中的第二阀门122打开，以将最后一级油气 分离装置即润滑油箱1的气体产物通过油气返回管道30返回冷凝装置82中以继续进行油气分离处理，从而形成闭路循环系统。在其他实施例中，油气返回管道也可以从润滑油箱1连接至第二油气输送装置821，以将润滑油箱1中的气体产物返回至冷凝装置82进一步进行冷凝处理，从而进一步进行油气分离。
例如，控制模块可以是但不限于：存储器、中央处理器、单片机、微处理器或者可编程逻辑器件。可以理解，存储器可以是易失性存储器或非易失性存储器。其中，非易失性存储器可以是只读存储器(Read-Only Memory，ROM)、可编程只读存储器(Programmable ROM，PROM)、可擦除可编程只读存储器(Erasable PROM，EPROM)、电可擦除可编程只读存储器(Electrically EPROM，EEPROM)或闪存。易失性存储器可以是随机存取存储器(Random Access Memory，RAM)，其用作外部高速缓存。通过示例性但不是限制性说明，许多形式的RAM可用，例如静态随机存取存储器(Static RAM，SRAM)、动态随机存取存储器(Dynamic RAM，DRAM)、同步动态随机存取存储器(Synchronous DRAM，SDRAM)、双倍数据速率同步动态随机存取存储器(Double Data Rate SDRAM，DDRSDRAM)、增强型同步动态随机存取存储器(Enhanced SDRAM，ESDRAM)、同步连接动态随机存取存储器(Synchlink DRAM，SLDRAM)和直接内存总线随机存取存储器(Direct Rambus RAM，DRRAM)。存储器旨在包括但不限于这些和任意其它适合类型的存储器。
例如，润滑油箱1作为多个级联的子油气分离装置中的最后一级。通常润滑油箱1包括气压平衡管道，气压平衡管道与润滑油箱1和大气相通，气压平衡管道中设置有过滤器，从而，润滑油箱1作为多个级联的子油气分离装置中的最后一级，可利用气压平衡管道作为气体排放管道3，利用润滑油箱1包括的过滤器4对所述润滑油箱1分离出来的气体产物进行过滤，过滤后的气体经所述气体排放管道进入大气，如此，不必在最后一级油气分离装置上额外设置气体排放管道和过滤器来进一步净化排入大气的气体，简化结构，节约成本。
图8A为图7中的冷凝装置的示意图一。如图8A所示，冷凝装置包括多个冷凝管820，所述多个冷凝管820内通有冷凝液且沿第一方向延伸，油气 经过所述多个冷凝管820的外壁，油气中的油在冷凝管820的外壁液化，沿冷凝管820的外壁流动而被汇集到输油装置9中，经输油装置9输送至润滑油箱中。例如油气沿与第一方向垂直的方向输入，当然油气也可以沿其他方向输入。
图8B为图7中的冷凝装置的示意图二。如图8B所示，多个冷凝管820的每个的外壁的轮廓形状包括整体上沿第一方向延伸的弯折，所述油气沿所述第一方向经过所述冷凝管820的外壁。如此，油气的气流在流经多个冷凝管820的弯折的外壁的过程中，油气中的大量微小的油滴更多地在弯折的外壁上发生碰撞，利于提高油气中油的液化速率和液化量，从而提高油气分离的效率和效果。例如，弯折呈折线状。当然，在其他实施例中，弯折也可以呈波浪线状等其他性质，本公开实施例对此不作限定。整体上沿第一方向延伸的弯折是整个外壁的轮廓形状沿第一方向延伸，且包括弯折部分，单个的弯折单元例如一个折线单元未必严格地沿第一方向。
图9为本公开一实施例提供的又一种油气处理系统的示意图。例如，如图9所示，该油气处理系统与图7所示的油气处理系统具有以下区别。在图7所示的油气处理系统的基础上，多个级联的子油气分离装置还包括前级别子油气分离装置81；油气通过第三油气输送装置23输送至前级别子油气分离装置81中，例如第三油气输送装置23包括油气输送管道；前级别子油气分离装置81配置为对油气进行冷凝处理以使油气中的油液化，与冷凝装置82级联且位于冷凝装置82之前。经前级别子油气分离装置81对油气处理后的气体产物通过第四油气输送装置24进入冷凝装置82中以进行下一级油气分离，经前级别子油气分离装置81对油气处理后的油产物通过第一输油装置91输送至润滑油箱1中，以回收利用，以用作对油雾产生装置等设备的润滑油。例如，第四油气输送装置24包括油气输送管道。经冷凝装置82对油气处理后的气体产物通过第一油气输送装置2进入润滑油箱1中以进行下一级油气分离，经冷凝装置82对油气处理后的油产物通过第二输油装置92输送至润滑油箱1中，以回收利用，以用作对油雾产生装置等设备的润滑油。例如，油气返回管道300连通最后一级子油气分离装置即润滑油箱1与前级别子油气分离装置81。控制模块配置为：若气体排放管道3中的气体的油含量 小于等于标准值，控制第一阀门121打开以将最后一级油气分离装置即润滑油箱1的气体产物通过气体排放管道3排入大气，且配置为：若气体排放管道3中的气体的油含量大于所述标准值，控制第一阀门121关闭，且控制位于油气返回管道300中的第二阀门122打开，以将最后一级油气分离装置即润滑油箱1的气体产物通过油气返回管道300返回前级别子油气分离装置81中以继续进行油气分离处理。当然，油气返回管道300可连通最后一级子油气分离装置即润滑油箱1与前级别子油气分离装置81和/或冷凝装置82，即油气返回管道连通所述最后一级子油气分离装置与所述多个级联的子油气分离装置的至少之一。例如，前级别子油气分离装置81为油气分离器，可采用本领域常规技术。图7中的润滑油箱1进行油气分离的方式如之前的实施例中所述，在此不再赘述。
例如，基于图9所示的油气处理系统，在其他实施例中，油气处理系统可以包括多个级联的油气处理器81；也可以在润滑油箱1之后设置一个油气处理器或多个级联的油气处理器或冷凝装置。
在图7所示的实施例中，油气处理系统包括前级别子油气分离装置，即冷凝装置82，前级别子油气分离装置与所述润滑油箱1级联且位于所述润滑油箱1之前。例如，在另一些实施例中，油气处理系统还可以包括后级别子油气分离装置，后级别子油气分离装置与所述润滑油箱1级联且位于所述润滑油箱1之后，配置为对所述润滑油箱分离出来的气体产物的至少部分进行后级别油气分离处理。如此，可利用润滑油箱1处理大量的油雾，以减轻后级别子油气分离装置的负担，减小后级别子油气分离装置的处理量，利于提高后级别子油气分离装置的使用寿命，节约成本。
图10A为本公开一实施例提供的又一种油气处理系统的示意图，图10B为与图10A中的机底润滑油箱相配合的油气产生装置的示意图。如图10A-10B所示，例如油气产生装置为涡轮发动机。例如，油气处理系统10还包括机底润滑油箱104和机底输油装置。机底润滑油箱104位于油气产生装置的底部，内置有润滑油。例如油气产生装置包括动力输出模块101、与动力输出模块101连接的空气压缩机102和与空气压缩机102连接的燃烧室103。例如燃烧室103位于空气压缩机102的远离动力输出模块101的一侧, 燃烧室103中设置有涡轮机的叶片。动力输出模块101配置为将燃烧室中涡轮机的叶片旋转所产生的动力传输给工作机。例如，动力输出模块101包括轴和轴承，例如该轴与涡轮机的叶片的转盘连接以传输涡轮机的叶片旋转所产生的动力。具体的涡轮发动机的结构设计可参考本领域常规技术，本公开对此不作限定，图10B仅为示例性的。例如，在图10B所示的实施例中，机底润滑油箱104位于动力输出模块101的底部，且配置为对油气产生装置进行润滑，例如包括对油气产生装置的动力输出模块101、空气压缩机102和燃烧室103中至少之一中需要润滑的部件进行润滑，例如上述轴和轴承等。例如，可通过管道将机底润滑油箱104中的润滑油输送至需要润滑的部件上。如图10A所示，机底输油装置配置为将多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置分离出来的油产物输送至机底润滑油箱104中，以将油产物用作润滑油，实现油产物的重复利用。
在油气产生装置处于工作状态时，机底润滑油箱104中的气压大于大气压，通常多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置中的气压与大气压相平衡，即此时机底润滑油箱104中的气压大于多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置中的气压；在油气产生装置处于非工作状态时，机底润滑油箱104中的气压基本等于大气压。这种情况下，在油气产生装置处于工作状态时，在不施加强制力的作用下，油产物在机底润滑油箱104与多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置之间的气压差的作用下，不能够从多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置自然流入机底润滑油箱104。如图10A所示，例如，机底输油装置为单向输油装置，且包括机底输油管道和单向阀123。机底输油管道配置为收集和输送所述油产物。例如，机底输油管道包括第一机底输油管道93、第二机底输油管道94和汇总机底输油管道95。例如单向阀123位于汇总机底输油管道95中，且配置为在油气产生装置处于非工作状态下，使机底输油管道单向导通以控制油产物通过单向阀123从多个级联的子油气分离装置当中除润滑油箱之外的子油气分离装置被输送至机底润滑油箱中104，而不允许机底润滑油箱104中的润滑油经单向阀123被朝向多个级联的子油气分离装置当中除润滑油箱1之外的子 油气分离装置输送，以防止机底润滑油箱104中的润滑油倒流至多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置中。例如，第一机底输油管道93配置为将前级别子油气分离装置81的油产物输送至机底润滑油箱104；第二机底输油管道93配置为将冷凝装置82的油产物输送至机底润滑油箱104；汇总机底输油管道95将第一机底输油管道93和第二机底输油管道94中的油产物汇集。在其他实施例中，也可以分别在第一机底输油管道93和第二机底输油管道94中设置单向阀。
例如，多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置，例如前级别子油气分离装置81和冷凝装置82，在重力方向上的位置高于机底润滑油箱104在重力方向上的位置，即在工作时，多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置相对地面的高度高于机底润滑油箱104相对地面的高度，以使得在油气产生装置处于非工作状态下，多个级联的子油气分离装置当中除润滑油箱1之外的子油气分离装置的油产物可在重力作用下流入机底润滑油箱104中，比必另外设置动力装置例如油泵来将所述油产物输送至机底润滑油箱104中，简化油气处理系统的结构。
例如，本公开至少一实施例还提供一种油气处理方法，用于本公开实施例提供的任意一种油气处理系统。该油气处理方法包括：将所述油气至少部分输送至所述润滑油箱内，所述润滑油箱对输送到所述润滑油箱内的油气进行分离，分离出来的油产物留在所述润滑油箱内。
例如，所述润滑油箱内置有润滑油，油气处理方法还包括：并且将所述油气喷射至所述润滑油的液面上；或者，油气处理方法还包括：将所述油气喷射至所述润滑油箱的内壁上；或者，所述润滑油箱内设置有阻挡结构，油气处理方法还包括：将所述油气喷射至所述阻挡结构上。
例如，油气处理方法，包括：将所述油气从所述油气产生装置直接通入所述润滑油箱内。
例如，在气分离装置包括多个级联的子油气分离装置时，每级子油气分离装置对所述油气进行油气分离处理，上述润滑油箱作为所述多个级联的子油气分离装置之一。并且，在油气处理系统10包括气体排放管道3、油量检测模块11、第一阀门121、油气返回管道30和控制模块时，油气处理方法还 包括：检测所述气体排放管道中的气体的油含量；以及判断所述油含量是否达到排放标准，若所述油含量小于等于标准值时，控制所述阀门打开以将所述最后一级子油气分离装置的气体产物通过所述气体排放管道排入大气；若所述油含量大于所述标准值，控制所述阀门关闭并将所述最后一级子油气分离装置的气体产物返回所述多个级联的子油气分离装置的至少之一中以继续进行油气分离处理。
例如，油气处理方法包括：将所述多个级联的子油气分离装置当中除所述润滑油箱之外的子油气分离装置的油产物输送至所述润滑油箱中例如，该油气处理方法，包括：对所述油气进行冷凝处理以使所述油气中的油液化。
具体的处理方法和工艺流程可参考对于图1-9所示的油气处理系统的实施例中的描述，不再重复。对于图1-9所示的油气处理系统的实施例中的特征和技术效果适用于本公开所有的保护主题。
本公开至少一实施例还提供一种机械设备。如图11所示，该机械设备100包括本公开实施例提供的任意一种油气处理系统。该机械设备100还包括油气产生装置、减速机和工作机；油气产生装置包括发动机；所述发动机为所述工作机提供动力，所述减速机连接在所述发动机和所述工作机之间。上述润滑油箱配置为向发动机、所述减速机和所述工作机中的至少之一提供润滑油。例如，工作机包括任何需要发动机为其提供动力的装置。例如，该机械设备为压裂设备，工作机包括柱塞泵。例如，在其他实施例中，例如，该机械设备为压裂设备，工作机还可以包括发电机。当然，机械设备也可以为其他类型的设备。
