Embodiment Construction

[0033] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0034] Such as figure 1 and figure 2 As shown, the reactor for microalgae outdoor cultivation of the present invention includes: a reactor unit 1 placed outdoors, an algae liquid delivery pipe, a carbon dioxide delivery pipe 3, a microalgae harvesting system 4, a delivery pump 72 and a flow control device Wait. Wherein, the algae liquid delivery pipe further includes a fresh algae liquid delivery pipe 21 , an algae liquid return pipe 22 and a connecting pipe 23 .

[0035] Such as figure 1 and figure 2 As shown, the reactor unit 1 has a stepped structure, and is connected by a plurality of water drop stilling units 11 that are lowered step by step from the upstream end to the downstream end. The upstream end of each water drop stilling unit 11 protrudes upward. The overflow weir 12 forms a recess for accommodating the algae liquid between the...

Abstract

The invention discloses a reactor for microalgae outdoor breeding, including a reactor unit (1) located outdoor, a microalgae harvesting system (4) and an algal liquid circumfluence tube (22), etc., wherein, the reactor unit (1) is in ladder-like structure, is connected by a pluratliy of step-by-step reduced water-drop force eliminating unit (11) whose upstream side is convex with overflow weir (12) from upstream to downstream; when the algae body flowing from the upstream to the downstream meets the required concentration, the microalgae is harvested by the microalgae harvesting system (4), when it does not meet the required concentration, the algal liquid is transferred and returned to the upstream of the reactor unit (1) through the algal liquid circumfluence tube (22). The inventive reactor uses ladder-type flow to generate onflow, so that the distribution of the algae body in the algal liquid is more uniform, the invention has more higher carbon dioxide utilization, low-cost, easy maintenance and repair, the specific algal species and methods can not easily be polluted by imported microalgae, and is suitable for large-scale, low-cost, continuous or semi-continuous breeding of microalgae.

Description

technical field [0001] The invention relates to equipment for cultivating microalgae, in particular to a reactor for cultivating microalgae outdoors, which is suitable for cultivating microalgae outdoors on a large scale and at low cost. Background technique [0002] There are two main types of traditional microalgae cultivation reactors: closed reactors and open reactors. Closed reactors mainly include tubular reactors, vertical plate reactors, bag reactors, and stirred tanks. Closed reactors are not easy to pollute during the breeding process, and the concentration of algae in the water is high. The algae breeding process is easy to control, but the closed reactor also has the following disadvantages: 1. Because the algae liquid is affected by light and absorbs a lot of heat, the internal temperature of the reactor rises, so the breeding process requires a lot of heat exchange equipment and consumes a lot of energy; 2. . Closed reactors usually need to be equipped with ar...
