Description
Technical field
The utility model relates to a kind of recovering device utilizing the concentrated raceway pond microalgae cell of microbubble recoil, belongs to microdisk electrode engineering field.
Background technology
Micro-algae, as the most important primary producer of nature, has started to play an important role in fields such as food, medicine, makeup, fine chemistry industries.Recently, day by day exhausted along with the fossil energy such as oil, coal, causes the great attention of people because of its recyclability based on the clean bioenergy of biomass.Micro-algae, fast growth, culture cycle is short, and fat content is high, and the environment that saltings, beach etc. can be utilized to be not suitable for Farming cultivates; Therefore the most promising bioenergy candidate species are called as.
During micro-algae large-scale is cultivated, the open cultivation based on raceway pond is with a long history, with low cost, is used rate the highest.But this training method also has some shortcomings: the efficiency of light energy utilization is low, and utilization rate of carbon dioxide is low, be affected by the external environment larger.Therefore, its algae cell density cultivated is also relatively low.And in the results link of micro-algae, except spirulina, other most of micro-algae kind is all based on collected by centrifugation.And whizzer price is high, energy consumption is also very big; The ratio of cost in both culturing microalgae cost of harvested by centrifugation is very high, can reach 1/3rd of total cost.If effective initial concentration can be carried out to micro-algae before collected by centrifugation, effectively can improve the collection effciency of whizzer, reduce energy consumption, and therefore significantly reduce the cost of microdisk electrode.
At present, before microalgae harvesting, most manufacturer adopts and algae liquid is transferred to settling tank by natural subsidence to reach the object of the micro-algae of initial concentration.This method has following shortcoming: 1, and settling efficiency is lower; 2, in settling process, because most cell is in dark surrounds, along with the prolongation of settling time, total biomass there will be suitable loss; 3, bacterium easily grows; 4, the energy consumption of transfer algae liquid is very large; 5, to some algae kind, centrifugal rotational speed arranges lower, cannot efficient concentration, arranges too high, can cause cell rupture problem.
Microbubble in water body can be attached to fine particle and micro-algae, and when discharging a large amount of microbubble in culture system, due to pneumatically supported effect, frustule will in a large amount of enrichment of fluid surface.If the frustule in large unit of water body can be enriched to by air supporting effect the surface of subsection water body, and utilize the effect of current, this part algae liquid is transferred to collection tube, will realize centrifugal before frustule initial concentration.This measure effectively can reduce the toxigenic capacity of micro-algae, and controls micro-algae quality.
Utility model content
