The utility model belongs to the technical field of algae culture devices. The greenhouse algae culture facility comprises a supporting frame, a treatment bin is arranged on the front face of the supporting frame, a switch is arranged on the outer surface of the treatment bin, a water outlet pipe is arranged on the right side of the treatment bin, a second valve is arranged on the upper surface ofthe water outlet pipe, and a water inlet pipe is arranged on the left side of the treatment bin. The utility model is advantageous in that the structure is simple, the water pump is effectively matched with the water pipe; people can conveniently obtain water to culture algae; effective action through a filter screen, the algae loss is prevented in the process of adjusting the culture solution bypeople; through the effective action of a clamping groove and a connecting block, a motor can drive a culture pipe to rotate, so that algae are sufficiently illuminated, through effective cooperationof a supporting frame and a base, the stability of the culture pipe is guaranteed, and the situation that the culture pipe swings in the algae culture process, and culture liquid leaks is prevented.
