Description
Technical field
The utility model relates to a kind of device utilizing microbubble to continue air supporting collection raceway pond frustule, belongs to microdisk electrode engineering field.
Background technology
Global industry process is accelerated to cause demand for energy constantly to increase, and traditional fossil energy has non-renewable, and reserves are reducing day by day.Estimate according to associated specialist, oil can also continue exploitation 41 years, and coal is 155 years, and Sweet natural gas is 53 years, and the research and development of renewable energy source have been the problems being badly in need of solving; In addition, the waste gas of the burning generation of fossil energy, refuse, waste liquid cause the pollution being difficult to repair to environment, had a strong impact on the health of ecotope and the mankind.Study, develop a kind of renewable, environmentally friendly energy to meet the energy demand of the mankind, reducing the destruction to environment, is the key subjects urgently to be resolved hurrily of facing mankind.Bioenergy carries out by various biorenewable raw material the energy produced, and comprising fuel hydrogen manufacturing, biofuel, alcohol fuel, biomass granule fuel etc., is a kind of renewable, environmentally friendly new forms of energy.At present, the exploitation of bioenergy have made great progress, and are described as the most possible novel energy replacing fossil energy.Micro-algae has the features such as fat content is high, culturing process does not occupy cultivated land, growth cycle is short, fast growth; Therefore the most promising bioenergy candidate species are called as.
During micro-algae large-scale is cultivated, raceway pond is that main open cultivation is with low cost because of it, and technical threshold is lower and be widely used in the cultivation of multiple micro-algae.But this training method also has some shortcomings: be subject to weather influence and very greatly, easily suffer the pollution of protozoon and assorted algae, the easily utilization ratio of breed bacteria, light and carbonic acid gas low.Therefore, its algae cell density cultivated is also relatively low.In the results process of micro-algae, except spirulina, other most of micro-algae kind is all based on collected by centrifugation.Whizzer not only price is high, and energy consumption is also very big; The ratio of cost in both culturing microalgae cost of harvested by centrifugation is very high.When the density of algae liquid is very low, the energy consumption needed for collected by centrifugation will double; Not only increase the cost of microdisk electrode, also have a strong impact on the work-ing life of whizzer.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, all algae liquid in raceway pond are transferred to settling tank natural subsidence by most manufacturer, will shift the algae liquid of settling tank middle and upper part to raceway pond recycle again after sedimentation terminates.The object of initial concentration algae liquid is reached by this kind of mode.The method is consuming time very long, and for dwelling property algae of the non-end, effect is also not satisfactory.In addition, because in settling process, most micro-algae is all in dark environment, so micro algae biomass also can suffer suitable loss.Meanwhile, also easy breed bacteria, and transfer algae liquid also can produce huge energy consumption repeatedly.
Microbubble in water body can be attached to fine particle and micro-algae, and frustule is subject to the impact of bubble buoyancy, can float up to water surface.By scattering a large amount of microbubble in water body, frustule is enriched in water surface.If only this part algae liquid can be transferred to settling tank or whizzer, effectively will reduce energy consumption, improve centrifugal efficiency, reduce microdisk electrode cost.Meanwhile, compared with traditional natural subsidence method, also can reduce the impact on micro-algae quality.Realize real-time to frustule, effective initial concentration by appropriate means, the centrifugal efficiency of micro-algae can be increased substantially, reduce the toxigenic capacity of micro-algae.
Utility model content
Technical problem to be solved in the utility model is: provide that a kind of cost is low, the frustule initial concentration device of ease of assembly and dismounting, with can before algae liquid be transported to whizzer, what continue carries out concentrated collection to frustule, thus improves centrifugal efficiency, reduces production cost.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of device utilizing microbubble to continue air supporting collection raceway pond frustule that the utility model provides, be made up of the separating device that other region separation of collection hole and raceway pond is opened and micro bubble generation device, micro bubble generation device and collection hole are positioned at different regions, and micro bubble generation device is arranged at the bottom of the pond of raceway pond.
The utility model provides a kind of separating device, its concrete structure is: be made up of air supporting plate and draw-in groove, at the bottom of the both sides pool wall that draw-in groove is arranged on raceway pond end and pond, at the bottom of the both sides pool wall that raceway pond end is fixed on by draw-in groove in air supporting plate both sides and downside and pond, by draw-in groove, air supporting plate is fixed on raceway pond end semicircular area, thus other region of a part of region around collection hole and raceway pond is effectively separated.
Preferably, air supporting plate can move up and down along the draw-in groove on the pool wall of both sides.
Preferably, the angle of air supporting plate and runway pool wall is between 10-30 degree.Further, the angle of air supporting plate and runway pool wall is 15 degree.
Preferably, air supporting plate width is the 1/4-2/3 of raceway pond total width; Air supporting plate height, lower than runway pool wall height, to be consistent with algae liquid level or higher than algae liquid level 1-3cm.
Preferably, draw-in groove both sides by bonding aluminium alloy structure to raceway pond sidewall or reserved or dig staking gap and build on runway pool wall; Draw-in groove at the bottom of pond builds by reserving or dig staking gap at the bottom of pond.
Preferably, air supporting plate is connected with draw-in groove is detachable.
Preferably, air supporting sheet material matter is the thin plate with certain elastic synthetic glass, polyethylene, polyvinyl chloride, polypropylene, polyester, rubber, resin.
Air supporting plate, towards water (flow) direction, is fixed on raceway pond end semicircular area by draw-in groove by the utility model, the collection hole of raceway pond and other region of raceway pond is effectively separated.Air supporting plate height and liquid level are consistent or a little more than liquid level 1-3cm; When microdisk electrode is to suitable density, open micro bubble generation device, micro bubble generation device scatters a large amount of microbubble, and the frustule in air supporting plate front is subject to air supporting effect, can assemble in a large number in water surface; Due to algae liquid move to air supporting plate place time, be subject to the stop of air supporting plate, this place's liquid level can a little more than the liquid level of raceway pond other parts; The highdensity algae liquid in top layer is crossed air supporting plate and is entered marker space and flow into raceway pond collection hole; Real-time, the lasting initial concentration to algae liquid can be realized by this device; Thus raising centrifugal efficiency, reduce results cost.
This device is for convenience detach, easily builds.
The utility model has the following advantages compared with existing frustule initial concentration mode: the concentrated frustule that (1) the utility model can be effective, real-time, whole link only can produce a small amount of energy consumption.(2) problem such as bacteria breed, biomass loss can not be caused.(3) the utility model structure is simple, and ease of assembly is dismantled.(4) the utility model is with low cost, easily manufactures, and efficiency is high, contributes to the production cost reducing micro-algae large-scale cultivation.
