请参阅图1及图2，本发明的油烟分离装置10，用于排烟装置100，油烟分离装置10包括第一支架12、第二支架14、多个第一分离板16及多个第二分离板18，多个第一分离板16与第一支架12固定连接，多个第二分离板18与第二支架14固定连接，多个第一分离板16和多个第二分离板18上下交错间隔设置，第一分离板16与第二分离板18相互部分地覆盖以形成多个分离通道19，第一支架12与第二支架14可移动地连接以调整每个分 离通道19的大小。
本发明实施方式的油烟分离装置10应用于排烟装置100时，可根据排烟装置100的风机20的风量手动或自动的调节第一支架12和第二支架14的相对位置，进而调整分离通道19的大小，这样会减少油烟分离装置10对油烟的阻力，提高抽吸油烟的效果，同时，噪音也较小，进而提升了用户体验。
具体地，油烟气流进入油烟分离装置10后，流至分离通道19，当排烟装置100的风机20的风量较大时，分离通道19内的流量增大，此时可通过调整第一支架12和第二支架14的相对位置，使分离通道19变大，避免因分离通道19过小而造成较大的阻力，影响油烟抽吸效果。同理，当排烟装置100的风机20的风量较小时，分离通道19内的流量小，而油烟通道相对过大，可通过调整第一支架12和第二支架14的相对位置，使分离通道19变小，增大油烟气流中的油烟颗粒的相互碰撞次数，使更多的油烟颗粒附着在第一分离板16和/或第二分离板18上，保证油烟分离效果不受风机20的风量的大小的影响。
进一步地，本发明的油烟分离装置10结构简单，清洗方便，节省用户清洁时间，提升用户体验。
请参阅图1～图4，在某些实施方式中，第一支架12包括第一横杆122和与第一横杆122垂直且位于第一横杆122两端的两个第一竖杆124，多个第一分离板16固定在第一横杆122上；
第二支架14包括第二横杆142和与第二横杆142垂直且位于第二横杆142两端的两个第二竖杆144，多个第二分离板18固定在第二横杆142上，
第二竖杆144上设置有竖直方向的凹槽1442，第一横杆122的端部和第一竖杆124可滑动地嵌入凹槽1442内。
如此，可沿第一竖杆124滑动第二支架14，根据排烟装置100的风机20的风量的大小调整分离通道19的大小以获得较好的油烟分离效果。
具体地，设置在第一横杆122上的多个第一分离板16与设置在第二横杆142上的多个第二分离板18上下交错间隔设置，形成分离通道19。
在某些实施方式中，第一分离板16和第二分离板18呈条状，第一分离板16的中间部位与第一横杆122固定连接，第二分离板18的中间部位与第二横杆142固定连接。
如此，第一横杆122为第一分离板16提供安装支撑，使第一分离板16稳定地安装在第一横杆122上；第二横杆142为第二分离板18提供安装支撑，使第二分离板18稳定地安装在第二横杆142上。
在某些实施方式中，第一分离板16的截面呈弧形，第二分离板18的截面呈弧形。
如此，圆弧状的分离板形成的分离通道19对油烟气流造成的阻力较小。
具体地，将第一分离板16和第二分离板18设计为圆弧状，没有死角，便于用户清洗第一分离板16和第二分离板18，使清洁更加彻底，避免死角存留油烟污渍导致细菌累积。
进一步地，第一分离板16的凹面朝向油烟分离装置10的内侧设置，第二分离板18的凹面朝向油烟分离装置10的内侧设置。
在某些实施方式中，每个分离通道19包括沿气流方向依次连接的第一转向段192和第二转向段194，第一转向段192用于将气流转向180度，第二转向段194用于将第一转向段192输出的气流转向180度。
如此，油烟气流进入分离通道19后，经两次180度转向，使油烟颗粒更容易附着在第一分离板16和第二分离板18上，提高油烟分离效果。
具体地，油烟气流经两次180度转向，使油烟气流的流动紊乱，湍流变强，也提高了油烟颗粒间相互碰撞的几率，使油烟颗粒积聚形成大颗粒，更容易从油烟气流中分离出来。
进一步地，油烟分离装置10包括多个进气口196和多个出气口198，进气口196与第一转向段192连通，出气口198与第二转向段194连通。
在某些实施方式中，第一支架12和第二支架14可拆卸地连接。
如此，在需要清洗油烟分离装置10上附着的油烟时，可方便快速地拆卸油烟分离装置10，由于第一分离板16和第二分离板18间隔设置，清洗空间也会变大，便于用户清洗油烟分离装置10内的污渍。
具体地，拆卸油烟分离装置10时，只需将第一支架12与第二支架14拆开，就可将油烟分离装置10分离成第一支架12及固定连接在第一支架12上的第一分离板16、第二支架14及固定连接在第二支架14上的第二分离板18两部分进行清洗，清洗完成后，再将第一支架12及固定连接在第一支架12上的第一分离板16安装至原位置即可，拆装过程简单便捷，非专业人员也可完成。
本发明实施方式的排烟装置100，包括上述任一实施方式所述的油烟分离装置10。
本发明实施方式的排烟装置100，可根据排烟装置100的风机20的风量手动或自动的调节第一支架12和第二支架14的相对位置，进而调整分离通道19的大小，这样会减少油烟分离装置10对油烟的阻力，提高抽吸油烟的效果，同时，噪音也较小，进而提升了用户体验。
在一个例子中，排烟装置为油烟机。
请参阅图5，在某些实施方式中，排烟装置100包括风机20、控制器30和驱动装置40，控制器30用于根据风机20的转速控制驱动装置40调整第一支架12和第二支架14的相对位置。
如此，控制器30根据风机20的风量实时地调整第一支架12和第二支架14的相对位 置，进而调整分离通道19的大小。
具体地，当用户将风机20的档位调大时，控制器30随之控制驱动装置40调整第一支架12和第二支架14的相对位置，使分离通道19变大，减小分离通道19的油烟气流造成的阻力，反之，当用户将风机20的档位调小时，控制器30也随之控制驱动装置40调整第一支架12和第二支架14的相对位置，使分离通道19变小，保证油烟分离效果。
在一个例子中，驱动装置40可驱动第二支架14相对于第一支架12移动。在某些实施方式中，第二竖杆144的内侧面可固定有齿条，驱动装置40通过齿轮组件驱动齿条以带动第二支架14相对于第一支架12移动。驱动装置40例如是电机。
在某些实施方式中，排烟装置100包括烟道50，油烟分离装置10安装在烟道50的内壁上，分离通道19与烟道50连通。
如此，将油烟分离装置10安装在烟道50上，油烟进入排烟装置100后，流至油烟分离装置10进行油烟分离，使分离后的气流从烟道50排出，保护环境，也减少了用户的清洗负担。
在某些实施方式中，烟道50包括进气段52，进气段52呈油烟气流方向渐缩的形状，第一支架12安装在进气段52的内壁上。
如此，将油烟分离装置10安装在渐缩状的进气段52处，使油烟以较大的流速进入油烟分离装置10，增加了油烟颗粒彼此间的碰撞机率及油烟颗粒粘附在第一分离板16和/或第二分离板18的机率。
具体地，在一个例子中，第一竖杆124固定连接在进气段52的内壁上。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合实施方式或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
