The joint mouth of abnormity section header can have only two of simple turnover to save mouth or a plurality of joint mouth; The medullary ray angle of cut between the joint mouth can have acute angle, right angle, obtuse angle, the straight angle or the shuttle parallel angle of cut.
3, the water conservancy diversion pedestal
Two groups of the stream of going out pedestal and backflow pedestals are arranged, be the long strip shape cabinet type structure, be built in the two ends of plastic film tube series respectively, with concrete prefabricated element assembling or directly build and form, also can form by glass reinforced plastic, hard plastic board or metal sheet.Section header is inlayed in water conservancy diversion pedestal front, and inside is the chicane of flowing water, and the passage at two ends is pressed section header and arranged with partition wall is staggered and separate, but in the confinement tube current shuttle circle round mobile.
Water-in 9 is arranged at the top that goes out to flow pedestal; There is water outlet 10 at the back, and the water outlet base portion has mud hole 11.Be positioned at the return flume 12 of mud hole below, hold and receive whole amounts of water to be discharged and be discharged into the next pond.
The backflow pedestal only plays the guide effect that current circle round, but the window 13 of breakdown is installed at the top, for the blowdown exhaust.The backflow pedestal is not established upper pond and return flume.
4. upper pond
For traversing out the long strip shape pond at stream pedestal top, available masonry material or concrete build up.
The potential in upper pond is higher than the Guan Ding plane.The pond height is decided by pondage and potential energy thereof, should satisfy abundant exchange and mixing that the current that enter pipeline can cause water body in the pipe.The water-in that is positioned at the bottom is a controlled mouthful of door, when liquid level rises to predetermined height in the pond, but the automatic breakdown of mat buoyancy tank lift or electromechanical device.Be the flow direction, flow velocity and the flow process of each pipeline water body of motor-driven adjusting, can establish many group water-ins and water outlet, the pipeline of every group of correspondence is all separate unit, is not communicated with alternate operation one by one during operation between each unit pipe mutually.
5. the next pond
The next pond is as the adjusting storage capacity of whole pipe series, stirring and the circulation that pondage need satisfy liquid in pipe.The potential in the next pond is lower than the pipe baseplane, and pool wall then should be higher than the Guan Ding plane.Pool wall should be used the Steel Concrete one-piece casting, or forms with glass reinforced plastic, hard plastic board, metal sheet, with anti-leak.
The water yield in the next pond is from return flume, and water outlet is then extracted out by the water lifting machinery of installing in the pond.In the flowing water passage that injects the pond, barrier is installed, screen frame 14 and deposition hole 15 make water body in working cycle, and it is dirty to stagnate automatically, and middle foreign matter intercepts water for sediment, hurdle.
6, water lifting machinery
The application of water lifting machinery is that the water yield in the next pond is taken out toward high-order pond.For avoiding the mechanical high-speed running to be directed at the frond damage, water lifting machinery should be selected for use: (1) electronic gas diaphragm pump; (2) windshield wiper device is as monomer-type or combination type waterwheel.
7. high-order pond
High-order pond is between the water stream channel in upper pond and the next pond, and its potential is higher than upper pond.It directly holds and receives water pump and come water, again to inject upper pond from stream mode by valve.
The function in high-order pond is: (1) is made for the expanding species pond, rare nutritive salt of analysing.(2) regulate the balance that passes in and out the water yield.(3) high velocity flow that injects is played the energy dissipating effect, and utilize the air supporting effect, remove suspended substance in the water.(4) control amount of water to be discharged.Before amount of water to be discharged enters upper pond, can carry out filtration, the collection 16 of algae.
8, the pipeline protection device
Pipeline protection is intended to guarantee that pipeline runs well, and improves use properties, extends using period.Concrete safeguard procedures and device thereof are referring to following variant production application pattern.
Again several patterns of answering of flexible duct culture systems are described below below:
1, open-air face of land training mode
As Fig. 1,2, shown in, the tabular form training mode only needs the smooth face of land can lay plastic film tube 1 in the open.At parallelpiped series two ends, set up out stream pedestal 2 and backflow pedestal 4 respectively, with the plastic film mouth of pipe and pedestal section header 2 tight fits.Go out to flow pedestal top, back, building upper pond 5, return flume 12 and corresponding intake-outlet 9,10.The return flume lower reaches is located in the next pond 6, and water lifting machinery 7 is installed in the pond, makes water outlet enter high-order pond 8.High-order pond is near upper pond and the next pond.Such device if cover the top of each open dug reservoir simultaneously, just constitutes open-air face of land training mode.
After required nutrient solution prepares in the device, start water lifting machinery, algae liquid is promptly risen to high-order pond and is flowed to upper pond by the next pond.When upper pond liquid level reaches predetermined height, open water-in, all algae liquid will enter plastic film tube around pedestal from top to down under action of gravity.Retrained by chicane, will in turn back and forth advance, finally through water outlet, the next pond of return flume involution along each pipeline.In producing operation process, if need to collect the algae powder, can flow to from high-order pond to settle between the upper pond at algae liquid and receive the algae device, algae liquid after the filtration still flows to upper pond, and then repeat above flow process, can realize that the whole process of algae liquid in flexible duct flows or circulation continuously, and in operational process, obtain the exchange mixing, to adapt to the growth of little algae.
This device except that flexible duct, the surplus hardened member that is.For guaranteeing safety, steady running, key is pipeline protection.Pipeline protection mainly is to prevent the pipeline breakage, and algae liquid leaks.For adapt to the ecological requirement that little algae is cultivated in pipeline, the defence burning sun in summer of still needing tans by the sun the pipe top, and for prolonging vegetative period in little algae year, at hypothermic phase pipeline is taked antifreeze insulation, heats measure in addition.Plastic film tube is difficult for taking place the big breakage of embrittlement because of flexibility is arranged.Mainly be to cause that because of quality is inhomogeneous micropore seepage or mechanical wound are directed at rhegma.Protection head ought look in advance, can the inspection of previous crops water-filling is being installed or the back is being installed do the inflation inspection in water, the leak of finding is subsidized plastic film with glue paste get final product.Breakage takes place in operational process, needs local discharge algae liquid, reduces hydraulic pressure or pipeline is raised repairing after softening under the water logging.Also can consider to set up the technique device that underwater emergency repairs handles.
Plastic film tube prevents that in summer the measure of tanning by the sun from having: (1) sets up water storage, pumping equipment in the pipeline plane, protect with waterflooding.When using this method, must run off to prevent water by film laying in the pipe baseplane; (2) set up the sunshade net; (3) scaffolding frame plantation sponge gourd etc. shelters from heat or light.
The insulation of plastic film tube between hypothermic phase heats measure, is included in duct bottom and installs insulating pad layer or electromotive force band, and the plastic film cover is set up at the top.When having hot spring or the spent hot water of factory to discharge, can be in plastic film tube the small-sized plastic film tube of suit, promptly tube-in-tube is imported the tubule internal recycle with hot water, so both can heat to algae liquid, the vertical convection that can produce heating power again mixes.
2, the floating training mode of the water surface
Fig. 3 is the structural representation of the floating training mode of the water surface.Because the ensemble average proportion of plastic film tube and inner nutrient solution thereof approaches water, overweights water slightly.Only need the water conservancy diversion foundation design to regulating the floating structure 17 of lifting, link 19, can be laid in the water surface, be engaged in the floatation type of little algae and cultivate simultaneously to the additional calibrator 18 of having buoyancy slightly of plastic film tube, and with positioning rope.
The key distinction of floating training mode of the water surface and open-air face of land training mode, be the surrounding medium difference, the operation of its culture apparatus and technical feature are also different: (1) is buoyant because of the water conservancy diversion pedestal, originally being fixed in high-order pond on the bank, upper pond and the next pond needs corresponding adjustment, or is replaced by unified floating appearance body.The form of pipeline under water body buoyancy toothed oak is used is tending towards right cylinder, and section header also need have corresponding change.Be the fluctuation that prevents water body, mobile and stormy waves impact, the location that needs to strengthen whole device, adjusting and management waterborne and maintenance.(2) seek photosynthesis for helping little algae, plastic film tube needs abundant daylighting, requires the place environment, and the water body clarification has water colour and transparency preferably.(3) the inner heat conduction of water body is fast, and at the beginning of Chun Modong, it is lower manage outer water temperature, and for prolonging the vegetative period of little algae in managing, plastic film tube should have the temperature raising and maintaining measure.
At above sport technique segment, the foundation of floatation type device needs to adopt following measure:
(1) cultivate in the waters that the selection stormy waves is little, range of water level little and be easy to control.As selecting to have arm of lake, the shallow water band of barrier, or swing in small-sized low-lying area.
For further weakening stormy waves, be convenient to management, and embellishing surface, can set up floating blanket formula pleuston wave eliminating band in the periphery, control region.In inside, control region, do water surface crop plantation landing, and utilize water surface space simultaneously, the submerged plant of planting is impelled the water body clarification.
(2) in the control region, waters, vertically beat spud pile 20 along pipeline at a certain distance, with the woven plain net of big eyelet from duct bottom toward coenvelope (21), in the both sides of net or the net buoyancy aid is installed, the structure of buoyancy aid can be formed with the vacuolar membrane plastic layer or with the steam cushion layer that the plastic film tube of inflating forms, and whole pipe can be floated under the holder with fluctuation in stage at bed course.Owing to adopt floating structure with the water conservancy diversion pedestal of pipe connection, make whole culture apparatus can be with change of level automatic lifting, or mat pulley lifting.
(3) in water temperature season on the low side, adopt the double-layer plastic film pipe that varies in size, internal layer is for cultivating the tubing of little algae, outer field bassoon, the tubing base portion between two pipes still with floating pad layer shop fixtures, makes two pipe joint places keep spacings, forms thermofin.Simultaneously with moulding circle or bamboo circle firmly, make get along well peripheral water body contact and being in the Greenhouse effect of tubing with bassoon typing expansion.
The another way of the floating cultivation of the water surface is to carry out in the pond.At this moment the plastic film tube of topping up is still buoyant.The water conservancy diversion pedestal then can be built in pool side regularly.In case the obvious fluctuation of water level takes place, and the adjusting of can drawing water makes stable level.This training method, behaviour's toothed oak is simple and easy, safety.
The water surface is cultivated little algae, as a kind of production model, can include the aquatic agriculture category in.Its enforcement can be quoted relevant technology and experience, thereby makes its unique advantage: (1) is land occupation not, saves grading and sash chemical industry journey.(2) in cultivation region, only need rational deployment, keep certain empty water surface, can culture freshwater shrimp, crab and some demersal fish.The combination water ecological environment treatment improves water quality simultaneously, can solve the production water source on the spot, realizes waters multiple use and three-dimensional development.(3) water surface is opened us, and sunny, the refraction of light and reflectivity are strong in the water, make also daylighting in various degree of duct bottom, help algal grown.(4) water body thermal capacity is big, and the water temperature luffing is little, and pipeline is laid in the water, but delaying retrogradation not only extend using period, still can alleviate or avoid summer high light and limit high temperature to the injury of algae.(5) under the water body buoyancy, the pipeline softening, tube wall stress is little, and osmotic pressure is little.In case damaged, leaks little, easily repairing.In addition, stormy waves, shipping agency can cause that all liquid in pipe stirs, and helps algal grown.As seen little algae is cultivated in the pipeline in water and has more ecological suitability.
3, indoor stereo training mode
Fig. 4 is the structural representation of indoor stereo training mode.Cultivate little algae at indoor employing flexible duct, can realize round-the-clock three-dimensional development.
Flexible duct is slim and graceful, lays simple and easyly, only needs at the indoor vertical demixing support 22 of holding up carrying screen frame 23 to be installed on each aspect of support, can lay pipeline, is engaged in little algae behind the topping up and cultivates.Because buildings blocks, a little less than room light shone, winter-spring air temperature was low, and this is unfavorable to micro algae growth.But can adopt modem technology to regulate and control,, window 25 more, warming-up device is installed winter as adopting printing opacity roof 24, summer, we opened a window etc., made indoor lighting, and temperature control performance improves, for micro algae growth is created optimum environment, thereby realize high-quality, high yield, and reduce cost.
Little algae indoor cultivation mainly is with the difference that both are cultivated in the open-air face of land, and the arrangement of pipeline dewaters square outside laying, but still multiwalled carries out vertical direction and lays.The liquid in pipe Recycle design that adapts with it, also different: on the one hand, it need keep the horizontal closed circulation in the same aspect; The aspect should embody three-dimensional circulation and receive the algae function in addition.For this reason, need to set up the networking of unified vertical vertical tube 26 and lateral duct,, the liquid between each aspect is exchanged by valve scheduling 27, running.
For saving the interior space, improve the structural stress of interior of building, guarantee safe handling, need not to establish in addition high-order pond here, the function in high-order pond will be replaced by the limited upper pond of volume.The next pond that is built under the face of land then needs suitable expansion capacity.
The liquid circulation mode of indoor cultivation mainly is a power cycle.But because the artificial regulatory ecological factor, at low temperature season, might utilize inside and outside the system is the altitude temperature difference effect of indoor and outdoor, realizes the thermodynamic cycle of pipeline liquid.At this moment need install in addition vertical vertical tube be laid in outdoor 28, utilize outside air temperature low, algae liquid sinks, indoor air temperature height, algae liquid come-up, thereby form closed loop.The fluid exchange that this circulation causes has stablely, continues, and relaxes and characteristics uniformly.
Indoor stereo is cultivated and has been embodied the industrialized production in agriculture direction, helps intensive farming.If 2000 meters of certain workshop pure land surface-area
2, by three layers of laying, getting each aspect average utilization is 0.75, is equivalent to 4500 meters
2Because round-the-clock running, can reach a times of open-air production phase (150 days), promptly 300 days year production phase.If realize artificial regulatory, make ecological factor reach good order and condition, day per unit area yield is by 10 gram/rice of open-air production
2Bring up to 15 gram/rice
2, then a year production algae powder amount can reach 20 tons, is equivalent to 13300 meters of open-air face of land culture area
2Product algae amount, promptly improve face of land utilization ratio more than 5 times.As seen adopt the indoor stereo that flexible duct develops little algae to cultivate, prospect is very wide.According to same principle, can utilize the interior space in the part, set up by power cycle temperature difference circulation or built-up type round-robin small test culture apparatus.
System of the present invention is used for the airtight cultivation of little algae and has brand-new characteristic, it had both had the superiority that the hard pipeline is cultivated little algae on the one hand, be convenient to remove the tube wall pollutent again, and can overcome oxygen saturation in the pipe, thereby can give full play to the effect of airtight cultivation, the outstanding advantage that it has with effect is: (1) investment unit price is low: compare with the hard pipeline, reduce cost significantly, and be starkly lower than the cost of open-air cultivation pool.(2) use range is wide: except that the field, still can be widely used in beach, flat or the saltings of arid area, desert band.It can also build up floating structure, directly lays on the wide water surface that swings in pond, lake.And can be used for the indoor layer stereo exploitation be engaged in.(3) enforcement is simple and easy, and its structure is slim and graceful, and materials are economized, and installs fast.Be used for the face of land, only need be smooth a little, need not to destroy Soil structure; Be used for the water surface, help daylighting, and can defend summer high temperature, it is aging to delay pipeline; Be used for indoor, but the industrialized production in agriculture direction is walked in three-dimensional development.In the whole production operation process, management maintenance is convenient.(4) structural entity has stability and security, and behind the plastic film tube topping up, the length of pipeline is much larger than width, width is greater than height (being liquid depth, in about 30cm), and manages the end and fit with underlying again, thereby Portugal, open and flat ground of whole pipe lies prostrate on the face of land, has whole stability.From mechanical analysis, pipeline all wts in the horizontal direction is by subgrade reaction institute balance, and in vertical, inner pipe water pressure power is then by the internal stress institute balance of both sides arc tube wall.Water pressure is limited, by unit length, is not more than 0.5kg/cm, or 17g/cm
2, much smaller than the ultimate stress of plastic film tube material.As seen the mechanical property of pipeline is safe.Under standard design, execution conditions, has reliability.(5) stirring of liquid in pipe can reach fully, and evenly, required drive is little, the saving energy.The recycle system of this device, the potential energy that can effectively utilize mechanical water lift to produce.When liquid when upper pond enters pipeline because tube wall is smooth, section is even, and is little to the water sports resistance, more because of pipeline has certain elasticity, not only produces water yield migration, also causes wave energy transmission in the pipe, and is directed at vibration repeatedly.Only need the interruption of finite aquifer to impact, can make vertical slip of liquid in pipe and level migration, reach fully, evenly stir.Because round-robin power comes from water pump, power is little, the saving energy.(6) whole device, pipeline structure is simple, and combination is compact, integrates circulation, removes contamination, receives algae, has found basic framework for realizing that the production automatic control is established.
Native system is the center to go out to flow pedestal, and each pond is closely faced mutually, and entery and delivery port can be regulated voluntarily, breakdown.Only need start picotan (water pump), can finish automatic receipts algae, algae liquid circulates, stirs and removes contamination in working cycle, and such textural association helps intensive farming, realizes automatic production.
