A kind of algal culture circulator,Alga culture device divides into culturing area and recovery zone,Culturing area, that is, algal culture circulator,Including water inlet pipe,First shunt group,Second shunt group,Cultivation pipe and recovery tube,Water inlet pipe connect Hou with preset cultivation water injecting device,It is separately connected the first valve body and the second valve body again,First valve body connects the first shunt group,Second valve body connects the second shunt group,First shunt group is extended with the first isocon and the second isocon,It is connected with third valve body,Second shunt group has each extended over third isocon and the 4th isocon,It is connected with the 4th valve body,Moveable resistance thruster is contained in cultivation pipe,And both ends are separately connected the first shunt group and the second shunt group,Then recovery tube is separately connected third valve body and the 4th valve body,The other end is connected to preset algae recyclable device,Thereby,Close the first valve body and the 4th valve body,The second valve body and third valve body are opened,Enable resistance thruster that algae water is pushed forward to inject recovery tube through the first shunt group,AndClose the second valve body and third valve body,The first valve body and the 4th valve body are opened,Enable resistance thruster that algae water is pushed inversely to inject recovery tube through the second shunt group,Reach cultivation pipe can directly carry out forward,Or the purpose of reverse algae water recycling.一種藻類養殖循環裝置，藻類養殖裝置區分為養殖區域與回收區域，養殖區域即所述藻類養殖循環裝置，包括入水管、第一分流組、第二分流組、養殖管與回收管，入水管與預設的養殖水注入裝置連接後，再分別連接第一閥體與第二閥體，第一閥體連接第一分流組，第二閥體連接第二分流組，第一分流組延伸有第一分流管與第二分流管，以第三閥體相連，第二分流組分別延伸有第三分流管與第四分流管，以第四閥體相連，養殖管內收容有可移動的阻推器，且兩端分別連接第一分流組與第二分流組，則回收管分別連接第三閥體與第四閥體，另一端連接至預設的藻類回收裝置，藉此，關閉第一閥體與第四閥體、開啟第二閥體與第三閥體，令阻推器推動藻水經第一分流組順向注入回收管，以及，關閉第二閥體與第三閥體、開啟第一閥體與第四閥體，令阻推器推動藻水經第二分流組逆向注入回收管，達到養殖管可直接進行順向、或逆向的藻水回收的目的。
