Summary of the invention
The present invention's first point is to utilize morning and evening tides to reduce the pumping cost.For example, at the incoming tide, the water of culturing algae can flow to the ground that is in level of ebb tide downwards along the gradient; And similarly, in the time of on the ebb, be in from the new algae of cultivating the pond and can flow in the marine floating framework downwards along the inclined-plane from the ground of rising tide water level.This has eliminated the huge cost of culturing algae on land.
Second of the present invention has provided a kind of framework, described framework allows and utilizes wave to stir the water body and the algae of growth wherein in this showy framework constantly, lasting stirring and then all algae are all exposed in the sun to promote growth naturally of algae.This has also eliminated another and has cultured the huge cost of algae on land, has improved whipping process simultaneously.
Thirdly of the present invention, provide a floating framework, in this floating framework, be the zone of algal grown, this zone and neighboring area isolate mutually.This framework can be an open-top, or complete closed and only stay a valve to allow superfluous air or carbonic acid gas discharge.
The 4th point of the present invention is to utilize the ashes behind the burning algae and concentrate the mineral matter of gained with used heat from seawater, as the nutrient of new talent.
The 5th point of the present invention is to utilize the less variation of ocean temperature and the big zone as the thermal energy exchange surface of the container in this floating framework, utilizes the ocean to change to keep the low of temperature in the somatomedin.
Further, with plant the crops on land by contrast, especially on land deficient and/expensive situation under, the ocean has more abundant space to support to grow algae, produce a large amount of biodiesel.Another advantage of the present invention promptly is in marine breed algae, the situation in soil just can not occur fighting for the edible crops of plantation.
Description of drawings
Objects and advantages of the present invention will be through the detailed description of the following example and in conjunction with the accompanying drawings, obtains more explicit manifesting:
Accompanying drawing 1 shows an embodiment of the floating framework in water body.In this example, the skeleton of this floating framework is to be made by bamboo pole or any other suitable material, and the material of formation container is plastics, rubber fabric or other suitable materials.Simultaneously also depict connection supply line on the bank, the water body that is used to transmit carbonic acid gas He contains algae.The quantity of conduit can increase and decrease according to need.For example, need adopt pipeline to transmission from the pipeline of the algae of cultivating the pond with receipts and separate if having, this can accomplish.
Accompanying drawing 2 is base stations of describing to be positioned on the bank by the sea wall protection, and it has be positioned at that flood tide waterline or above cultivation pond.In the time of on the ebb, from this cultivation pond the algae kind that contains the desire breed is flow to the framework of offshore downwards along the gradient, algae will grow in this framework.Also show carbon dioxide conduit, this carbonic acid gas is supplied to the algae that grows in the framework of offshore.When algae has grown to can gather the time, algae is taken advantage of at the incoming tide flow to downwards to be in or to be lower than in the sedimentation basin of level of ebb tide line along the gradient.
Accompanying drawing 3 shows and a kind ofly promotes the method for buoyancy by the head sea bamboo pole quantity of face of increase.
Embodiment
The base station will be built in seashore breakwater back, make the base station have from be higher than that flood tide the level of waterline to the gradient that is similar to or is lower than the level of level of ebb tide line.In fact this physical features level complys with the landform in natural coastline, transforms so need not emerging building.
Marine alga is cultivated the level place that the pond will be located at the waterline that is greater than or equal to that flood tide, and this flows into the water body that allows to contain algae in the floating framework according to the gradient that has a down dip on the ebb the time.Each independent floating framework will be by successively from cultivating the pond supply.
The growth field be in comprise skeleton floating framework on, the material of skeleton can be can be floating and keep any materials plastics, rubber, the films rubber fabric or other similar materials, as bamboo and wood or hollow plastics, make it possible to form a pond that isolates with water body on every side.This pond can be that cover or open.
An example of this framework is, skeleton wherein is that length and width are 20 meters the square or the square of other sizes, and wherein the inside of this skeleton or outside are attached with film, make to form water containing container.These frameworks will be by attached anchors and are linked one by one with in a plurality of current known modes any one in most cases, float avoiding.
Because these devices can run foul of each other because of the impact of wave through regular meeting, therefore need make enough firm, and must damping around it, for example settle old tire in each side.
During collection, water and algae can flow to the sedimentation basin that is lower than or is similar to the level of ebb tide line in the breakwater back at the incoming tide.
The algae that collects is fuel-displaced with refine, and its draff is then made following wherein purposes on the one hand: as medicine and health purpose, as the food of human, fish or other animals, fermenting produces ethanol (alcohol) and act as a fuel, produce methane or directly as fuel used to generate electricity by anaerobic digestion.The oils of institute's refine has multiple function like fish oil, can also be as biodiesel.
Under wherein a kind of situation, its draff can be used to fermentative production of ethanol, sells as the usefulness of biodiesel or with oil substitutes.Its draff can also combustion power generation, and the ashes that burnt till can be used as the fertilizer of algae new talent, and with the waste heat oven dry seawater of burning, obtains more mineral matter and nutrition and give the algae that is growing up.
The electric power of being produced can be for the usefulness of base station operation, as gathering, put forward oil and production biodiesel.Exhaustless electric power also can be sold electricity for net.
Size, shape and the structure that can design floating framework make it possible to improve the availability of stirring.For example, more if desired stirrings can be added the buoyancy that bamboo pole parts or other floatation device increase this side by the face of heading sea at framework, make that this side promotes more under each wave impact.Another changes the method for stirring is to adjust the length of floating framework along the wave direct of travel.Whether the length that for example, stirring degree will be looked this framework equates with the integral multiple of the wavelength of wave or the integral multiple of wavelength adds the wavelength of half and changes.
No matter be that algae or marine alga can grow in the afloat floating framework.In fact, algae grows more healthy and strongly marine, does not pollute because the algae kind can not occur, and more impossible have the marine alga kind to pollute.It is algae land breeding method greatest problem that kind is polluted.
The land breeding method uses closed system sometimes, is intended to avoid the algae in the container to be subjected to the kind pollution, is replaced by other stronger but non-kinds of fixing one's mind on.One of subject matter of this closed system is that it will accumulate the temperature of the sun as the greenhouse.This will allow the temperature of the interior growing environment of container high, influences into the long rate of algae.If have large-area thermal energy exchange surface, with seawater on every side good the contact arranged, the temperature of growing environment is moderate, and the rate of growth of the algae in it will be more effective.
