本申请要求申请号为201910912816.4、申请日为2019年9月25日的中国专利申请的优先权和权益，上述中国专利申请的全部内容在此通过引用并入本申请。
技术领域
本申请的实施例涉及一种藻培养系统，具体地涉及一种跑道式藻培养系统。
背景技术
藻，例如微藻，可以利用太阳能和水，吸收二氧化碳(CO2)，通过光合作用，合成油脂、淀粉、糖类物质、纤维素等多种生物质，而且藻生长周期短，生物量积累远远大于陆生植物。相关技术中的藻培养系统普遍存在生产率低、能耗和成本高的问题，因此，存在提高藻，尤其是微藻，的生长速率和整个系统的生产效率且降低水耗等的需求。
发明内容
本申请是基于发明人对以下事实和问题的发现和认识做出的：
相关技术中，微藻培养系统的生产效率低、水耗和成本高，发明人发现主要是以下几方面的原因：(1)在微藻培养过程中，微藻在跑道池内的微藻培养液中容易出现沉淀或分层流动中发生沉淀死藻，微藻沉淀在培养池的池底，发生腐烂，影响水质，进而会导致更多的微藻死亡，降低了微藻培养系统的产能。如果定期对沉淀的微藻进行清理，需要排空培养池内的微藻培养液，既浪费时间，又浪费能源，而且也会影响产能，此外，由于沉淀在池底的死藻很快会发生变质而影响水质，因此，即使定期清理，效果也有限。(2)跑道池露天或半露天，不但导致跑道池内的微藻培养液中的水分容易蒸发浪费，而且雨雪、昆虫、杂物等进入微藻培养液中对微藻培养液造成污染。
相关技术中，提出了在微藻的跑道池内分散布置多个阻挡部件，阻挡部件固定在培养池内，通过阻挡部件阻挡培养池内流动的微藻培养液，以避免微藻沉积在培养池的池底。然而，固定不动的阻挡部件对微藻培养液流动的阻力大，需要提供更多的能量推动培养池内的微藻培养液流动，存在能耗高的问题，而且由于阻挡固定不动，仅能避免阻挡部件附近的微藻沉积，效果差。如果设置许多阻挡部件，会进一步增加对微藻培养液的流动阻力。
本申请旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本申请提出了一种跑道式藻培养系统，该培养系统的跑道池可以增加微藻在微藻培养液中接受光照的机会，而且避免跑道池底面上的发生沉积，从而降低了能耗，提高了产能和生产效率。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。在本申请的描述中，需要理解的是，术语“中心”、“长度”、“宽度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
如图1-10所示，根据本申请实施例的跑道式藻培养系统包括跑道池1、推进部件2、第一扰流部件3和第二扰流部件8。
跑道池1为藻的培养池，该培养池呈跑道状，即跑道池1为跑道状的环形池。跑道池1包括第一直区段111和第二直区段112，以及第一弧形区段113和第二弧形区段114，第一弧形区段113连接在第一直区段111的第一端和第二直区段112的第一端之间，第二弧形区段114连接在第一直区段111的第二端和第二直区段112的第二端之间，即第一弧形区段113连通两个直区段的第一端，第二弧形区段114连通两个直区段的第二端。
换言之，如图1所示，跑道池1具有沿宽度方向间隔开的两个直区段：第一直区段111和第二直区段112。第一直区段111和第二直区段112通过内隔板102隔开。第一弧形区段113连通第一直区段111的右端和第二直区段112的右端，第二弧形区段114连通第一直区段111的左端和第二直区段112的左端。可选地，第一弧形区段113和第二弧形区段114均为半圆形，即第一弧形区段113为第一半圆区段，第二弧形区段114为第二半圆区段。可以理解的是，第一弧形区段113和第二弧形区段114并不限于半圆形，还可以为大于半圆或小于半圆的弧段。
在图1所示的示例中，内隔板102为一个直板或一段直的隔壁。可选地，可以在跑道 池1内设置一个跑道状的环形内壁以替代内隔板102，该环形内壁与跑道状的环形外壁之间限定出培养液流道，该培养液流道分成第一直区段111、第二直区段112、第一弧形区段113和第二弧形区段114。
推进部件2设在第一直区段111和第二直区段112中的至少一个内，用于推动跑道池1内的微藻培养液流动。如图1和图2所示，推进部件2设在第二直区段112内且可转动，例如推进部件2沿图2所示的推进部件2的转动方向16转动，从而促使跑道池1内的微藻培养液流动。在一些具体的实施例中，如图2所示，推进部件2包括桨轴21和多个桨叶22，多个桨叶22安装在桨轴21上且沿桨轴21的周向均匀间隔布置。在该实施例中，通过诸如电机的驱动器驱动桨轴21转动，由此带动多个桨叶22转动，从而推动跑道池1内的微藻培养液流动。在本申请的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
第一扰流部件3设在第一直区段111和第二直区段112中的至少一个内。第一扰流部件3与跑道池1的底面101间隔开预定的间隙，且与跑道池1的侧面103间隔开，其中跑道池1的侧面为跑道池1的侧壁的内表面。如图1所示，第一直区段111内和第二直区段112内均设有第一扰流部件3。
第二扰流部件8设在第一弧形区段113和第二弧形区段114中的至少一个内。第二扰流部件8与跑道池1的底面101间隔开预定的间隙，且与跑道池1的侧面103间隔开。如图1所示，第一弧形区段113和第二弧形区段114内均设有第二扰流部件8。
第一扰流部件3在第一直区段111内和第二直区段112可移动，以增加第一扰流部件3与跑道池1的底面101之间的微藻培养液的流速，即流过第一扰流部件3与跑道池1的底面101之间的间隙的微藻培养液的流速度增加，不但增加了第一扰流部件3和微藻培养液之间的相对速度，而且使微藻培养液产生紊流200，从而避免微藻300沉积在跑道池1的底面101上。这里，需要理解的是，第一扰流部件3与跑道池1的底面101间隔开的间隙是第一扰流部件3的下边沿与跑道池1的底面101之间的间隙。通过第一扰流部件3与跑道池1的底面101之间设置间隙，可以使流过该间隙的微藻培养液的流速度增加，产生紊流，防止微藻300沉积，而且可以避免第一扰流部件3刮蹭跑道池1的底面101，还可以增加微藻300曝露在光源(阳光或LED)下的机会，即使微藻更容易接受光照。
第二扰流部件8在第一弧形区段113和第二弧形区段114内可转动，以增加第二扰流部件8与跑道池1的底面101之间的微藻培养液的流速，即流过第二扰流部件8与跑道池1的底面101之间的间隙的微藻培养液的流速度增加，不但增加了第二扰流部件8和微藻培养液之间的相对速度，而且使微藻培养液产生紊流200，从避免微藻300沉积在跑道池1的底面101上，且增加微藻300曝露在光源(阳光或LED)下的机会，即使微藻更容易接 受光照。换言之，跑道池1的弧形区段设置可转动的第二扰流部件8，适应弧形区段结构的同时能够提高产生紊流200的效率，提高在弧形区段驱散微藻300的效果。
这里，需要理解的是，第二扰流部件8与跑道池1的底面101间隔开的间隙是第二扰流部件8的底面与跑道池1的底面101之间的间隙。通过第二扰流部件8与跑道池1的底面101之间设置间隙，可以使流过该间隙的微藻培养液的流速度增加，产生紊流，防止微藻300沉积，而且可以避免第二扰流部件8刮蹭跑道池1的底面101。此外，第二扰流部件8与跑道池1的侧面间隔开，可以避免第二扰流部件8刮蹭跑道池1的侧面。
在藻培养过程中，培养池内的微藻培养液中容易出现微藻(例如死的藻或在层流状态下沉积的微藻)，微藻沉淀在培养池的池底，容易影响水质，进而会导致更多的藻死亡，降低了藻培养系统的产能。如果定期对微藻进行清理，需要排空培养池内的微藻培养液，既浪费时间，又浪费营养物，而且也会影响产能，此外，由于沉淀在池底的死藻很快会发生腐烂而影响水质，因此，即使定期清理，效果也有限。
根据本申请实施例的跑道式藻培养系统，通过在跑道池1的直区段内设置与跑道池1的底面101和侧面103均间隔开且可移动的第一扰流部件3，以及在跑道池1的弧形区段内设置与跑道池1的底面101和跑道池1的侧面间隔开的第二扰流部件8，可以增加第一扰流部件3与跑道池1的底面101之间的微藻培养液的流速，以及增加第二扰流部件8与跑道池1的底面101之间的微藻培养液的流速，以在直区段和弧形区段均产生可以避免微藻沉淀的紊流200，从而防止微藻300沉积在跑道池1的底面101上，提高微藻对光的接触和减少对水质的影响，提高微藻生长速率和提高藻培养系统的生产效率，此外，第一扰流部件3在跑道池1内可移动和第二扰流部件8可转动制造紊流，可以比现有的固定紊流阻挡件减小对微藻培养液流动的阻力，降低推动微藻培养液在跑道池1内流动的能耗。而且，由于第一扰流部件3可移动和第二扰流部件8可转动，与固定的阻挡部件相比，可以在更大的区域内避免微藻沉积。
在一些实施例中，第一扰流部件3在跑道池1内可往复直线移动。如图1所示，第一扰流部件3可从左向右以及从右向左移动。具体地，如图3、4所示，当具有向右的拉力F时，第一扰流部件3的移动方向15为从左向右的方向，当具有向左的拉力F时，第一扰流部件3的移动方向15为从右向左的方向。
这里，可以理解的是，当第一扰流部件3的移动方向和跑道池1内的微藻培养液的流动方向相反时，第一扰流部件3和微藻培养液的相对速度较大，产生紊流的效果较强，从而防止微藻300沉积在跑道池1的底面101上的效果更好。如图5所示，第一扰流部件3的移动方向15为从左向右的方向，跑道池1内的微藻培养液的流动方向14为从右向左的方向，第一扰流部件3的下边沿和跑道池1的底面之间具有间隙，通过间隙的微藻培养液 的流速度增加，在第一扰流部件3的左侧产生紊流200，进一步增强了对微藻300的搅动效果，防止微藻300沉积在跑道池1的底面101上的效果也进一步增强。
第二扰流部件8在跑道池1内的两端弧形区段内沿弧的径向可往复转动。如图1所示，第二扰流部件8可从下向上转动，也可从上向下转动，例如第二扰流部件8沿图9所示的第二扰流部件8的转动方向17转动。这里，可以理解的是，当第二扰流部件8的移动方向和跑道池1内的微藻培养液的流动方向相反时，第二扰流部件8和微藻培养液的相对速度较大，产生紊流的效果较强，从而防止微藻300沉积在跑道池1的底面101上的效果更好。
在一些实施例中，第一扰流部件3和第二扰流部件8位于跑道池1内的液面100之下，由此可以更好地避免微藻300的沉积。
在一些具体的实施例中，如图7所示，跑道池1内的微藻培养液的液面高度为D，第一扰流部件3的下边沿与跑道池1的底面101之间的间隙的高度为A，其中A为5％-40％D。在一些实施例中，通过将第一扰流部件3的下边沿与跑道池1的底面101之间的间隙的高度设置成跑道池1内的微藻培养液的液面高度的5％-40％，可以增强紊流200，从而更好地防止微藻300沉积在跑道池1的底面101上。更优选地，A为10％-18％D。
这里，需要理解的是，第一扰流部件3的下边沿与跑道池1的底面101之间的间隙的高度为，第一扰流部件3的下边沿和跑道池1的底面101之间在上下方向上的距离。
进一步地，第一扰流部件3的高度为B，其中B为5％-50％D。在一些实施例中，通过将第一扰流部件3的高度设置成跑道池1内的微藻培养液的液面高度的5％-50％，可以增强紊流200，更好地防止微藻300沉积在跑道池1的底面101上。更优选地，B为20％-36％D。
这里，需要理解的是，第一扰流部件3的高度为，第一扰流部件3的上边沿与下边沿之间在上下方向的尺寸。
在一些实施例中，如图6和图7所示，第一扰流部件3可以为水平定向的大体V形且包括第一板31和第二板32，第一板31和第二板32沿跑道池1的宽度方向延伸。第一板31水平设置，第二板32的上边沿和第一板31的右边沿相连且第二板32位于第一板31下面，第二板32的下边沿与跑道池1的底面101之间的间隙即为第一扰流部件3与跑道池1的底面101之间的间隙。
即，第一扰流部件3与跑道池1的底面101之间的间隙的高度A为第二板32的下边沿与跑道池1的底面在上下方向上的距离，第一扰流部件3的高度B为第一板31与第二板32的下边沿在上下方向上的距离。
在一些具体的实施例中，第二板32相对于第一板31的倾斜角为10°-90°，即第一板31与第二板32之间的夹角为10°-90°。通过将第一板31与第二板32之间的夹角设置为 10°-90°，可以进一步增强紊流200，更好地防止微藻300沉积。更优选地，第一板31与第二板32之间的夹角为30°-60°。
在另一些可选的实施例中，第一扰流部件3构造为沿跑道池1的宽度方向延伸的扰流板，该扰流板具有圆形、三角形、矩形或T形的横截面，或者，扰流板为竖直板，如图8所示。

通过在第一支腿4下端设置第一滑板5，正常情况下，第一滑板5与跑道池1的底面101间隔开，即使第一扰流部件3偶然向下移位，第一滑板5接触跑道池1的底面101并在底面101上滑动，减小移动阻力，并且保证第一扰流部件3与底面101之间具有间隙。具体地，第一直板51水平设置，第一斜板52从第一直板51的两端向外延伸且向上倾斜。
通过在第一扰流部件3的两端设置第一滑板5，正常情况下，第一滑板5与跑道池1的侧壁103间隔开，即使第一扰流部件3偶然沿横向移位，第一滑板5可以与跑道池1的侧壁103接触，第一滑板5在跑道池1的侧壁103上滑动，减小阻力且使第一扰流部件3的移动更加平稳。具体地，第一直板51竖直设置，第一斜板52从第一直板51的两端向外延伸且朝向第一扰流部件3的中心倾斜。

在一些具体的实施例中，第一驱动组件7还包括第一滑轮73。第一绞绳72绕过第一滑轮73缠绕在第一绞盘71上。具体地，第一绞盘71和第一滑轮73位于跑道池1外侧。

第二半圆区段内，第二悬挂梁91的右端与第二驱动轮的下端面相连，第二悬挂梁91的左端与导引轮10的中心轴1011相连，导引轮10与跑道池1在第二半圆区段处的侧面103间隔开。两个连接臂92沿左右方向间隔布置，且每个连接臂92连接在第二悬挂梁91和上述另一个扰流梁之间。第二驱动轮通过第二悬挂梁91驱动上述另一个扰流梁在第二半圆区段内沿第二半圆区段的周向往复转动。
环形板11设在第一半圆区段内和第二半圆区段内，且环形板11的外周面与跑道池1的半圆区段处的侧面103相连，环形板11位于扰流梁上方且位于导引轮10下方，以便在第二悬挂梁91转动时，导引轮10在环形板11上方沿半圆形轨迹往复运动。
可以理解的是，第二电机124正反转可带动第二绞盘121正反转，第二绞盘121正反转可带动驱动轮122正反转，从而带动扰流梁可往复转动，其中驱动轮122的转动方向18如图9所示。例如第二电机124带动第二绞盘121顺时针转动时，第二绞盘121通过第二绞绳123带动驱动轮122转动，驱动轮122带动扰流梁沿一个方向转动；第二电机124带动第二绞盘121逆时针转动时，第二绞绳123带动驱动轮122转动，驱动轮122带动扰流梁沿与上述一个方向相反的另一个方向转动，从而实现扰流梁的往复转动。
