Problems solved by technology

In the prior art, there are multiple arc-shaped partitions in the middle of the reaction tank, the flow direction of the algae solution is constantly changing, and the turning angle is 180 degrees, and the turning point is a plane rather than an arc surface, so the flow resistance of the algae solution is strong and the energy loss is large. Large dead zone

Embodiment Construction

[0021] refer to figure 1 , the present invention is used for the culture tank of microalgae culture and comprises: pool bottom 1, the side wall 2 that is fixed on the pool bottom 1, along side wall 2, and the dividing plate 6 that extends at intervals with side wall 2, is positioned at Stirring paddle 7 between side wall 2 and partition 6 . Wherein, the outer end 3 of the side wall 2 is connected to the outer surface of the side wall 2 adjacent to the outer end 3, and the side wall 2 spirally extends along its longitudinal length direction.

[0022] Specifically, the culture pond is surrounded by a pond bottom 1 and a spiral side wall 2 fixed on the pond bottom 1 . Along the extension direction of the side wall 2, a partition 6 is provided at a distance from the side wall 2, that is, the partition 6 is also spiral. Preferably, along the longitudinal circumferential direction of the side wall 2, the distance from the partition plate 6 to the pool walls of the two adjacent sec...

Abstract

The invention provides a culture pond for culturing micro-algae. The culture pond comprises a pond bottom (1), a side wall (2) fixed on the pond bottom (1), a clapboard (6) which extends along the side wall (2) in a spacing mode, and a stirring paddle (7) which is positioned between the side wall (2) and the clapboard (6), wherein the outer end (3) of the side wall (2) is connected to the outer surface of the side wall (2) adjacent to the outer end (3), and the side wall (2) extends by helically coiling along the longitudinal length direction thereof. The invention aims to provide the culture pond which is used for culturing the micro-algae and has less flow dead zones during culture.

Description

technical field [0001] The invention relates to a culture pond, in particular to a culture pond for cultivating microalgae. Background technique [0002] The raceway pool is the oldest microalgae cultivation system, which was proposed by Oswakl in the 1960s and has been used until now, with little change in the main structure, and little research work has been done on it at home and abroad for decades. The runway pool is usually a ring structure, the depth of the culture medium is generally 15-30cm, and it has two or more circulating water channels, which are stirred by paddle wheels to promote the mixing of the culture medium. At present, the large-scale cultivation of microalgae mainly adopts open systems such as racetrack ponds. However, the simple structure of the runway pool will result in a high liquid level and a long optical path; the algae liquid has a long flow distance, and the flow rate of the lower layer of algae liquid is slow, which cannot be mixed and exchan...
