Description
Izgudrojums attiecas uz zivju audzēšanu, īpaši uz paņēmieniem un iekārtām ūdens piesātināšanai ar skābekli zivju audzēšanas baseinā ar noslēgtu ūdens nodrošināšanas sistēmu.The invention relates to fish farming, in particular to methods and devices for oxygenation of water in a fish farm with a closed water supply system.
Skābekļa saturs ūdenī ir viens no svarīgākajiem faktoriem, kurš nosaka zivju audzēšanas procesa efektivitāti. Zivs elpojot patērē skābekli. Nepietiekošs skābekļa 10 daudzums ūdenī ietekmē zivs barošanu un augšanu, un pat var izraisīt tās nāvi. Skābekļa ' trūkuma dēļ zivs nav spējīga asimilēt barību. Ūdenī izšķīdušo skābekli izmanto ne tikai zivis elpošanai, bet arī organisko un dažu neorganisko vielu oksidācijai, kuras atrodas zivju audzēšanas baseinā. Gadījumā, ja ūdens satur vairāk tādu vielu, oksidācijai tiek patērēts vairāk skābekļa un rezultātā zivīm ir grūtāk elpot.The oxygen content in the water is one of the most important factors determining the efficiency of the fish farming process. Fish breathes oxygen when breathing. Insufficient oxygen 10 in the water affects the feeding and growth of the fish and can even lead to death. Due to the lack of oxygen, the fish is unable to assimilate the feed. Water dissolved oxygen is used not only for fish breathing, but also for the oxidation of organic and some inorganic substances in the fish farming basin. If water contains more of these substances, more oxygen is consumed for oxidation and, as a result, it is more difficult for fish to breathe.
Noslēgta tipa zivju audzēšanas sistēmās augsta līmeņa piesātināšanas ar skābekli nodrošināšanai tiek izmantota ūdens piesātināšana (oksigenācija) ar tīru skābekli. Šajā nolūkā tiek izmantoti skābekļa konusi, kuros zem spiediena sajaucas ūdens un skābeklis. Šī paņēmiena trūkums ir liels enerģijas patēriņš ūdens pārsūknēšanai un daļēji arī nevienmērīgs skābekļa sadalījums ūdenī un pat ūdens pārsātinājums ar skābekli, kas arī 20 nelabvēlīgi atsaucas uz zivs veselību.In closed-type fish farming systems, oxygen saturation (oxygenation) with pure oxygen is used to provide a high level of oxygen saturation. For this purpose, oxygen cones are used which mix water and oxygen under pressure. The disadvantage of this technique is the high energy consumption for pumping water and, in part, the uneven distribution of oxygen in the water and even oxygen saturation of the water, which also adversely affects fish health.
Skābekļa un ūdens sajaukšanas princips tiek pielietots šahtas tipa oksigenātoros, kuros skābekļa padeves caurule tiek iegremdēta zemē un zem ūdens staba spiediens nodrošina skābekļa nokļuvi ūdenī. Šī paņēmiena priekšrocība ir ūdens pārsūknēšanas zemās izmaksas, bet tādas ūdens piesātināšanai ar skābekli (oksigenācijas) sistēmas 25 uzstādīšana ir sarežģīta un dārga. Ir zināmi daudzi izgudrojumu risinājumi, kuru mērķis ir zivju audzēšanas sistēmu ūdens piesātināšanai ar skābekli procesa izmaksu samazināšanai, bet lielākā dala šo risinājumu ir varianti ūdens sajaukšanai ar tīru (tehnisko) skābekli zem spiediena.The principle of oxygen-water mixing is applied in shaft-type oxygenators, in which the oxygen supply pipe is submerged in the ground and the pressure under the water column ensures that oxygen is released into the water. The advantage of this technique is the low cost of pumping water, but installing such an oxygenation system 25 is complicated and expensive. Many inventive solutions are known which aim to reduce the cost of oxygen saturation of fish farming systems with water, but most of these solutions are options for mixing water with pure (technical) oxygen under pressure.
Tuvākais piedāvātā izgudrojuma analogs ir ūdens piesātināšanai ar skābekli 30 aparāts (EP1094701), kurš ir izpildīts kā virs baseina peldoša iekārta, kura no augšas slēgta ar hermētisku kupolu. Hermētisko kupolu piepilda ar skābekli, bet tā iekšpusē zem spiediena tiek izsmidzināts ūdens, kurš sajaucas ar skābekli. Pēc tam ar skābekli piesātinātais ūdens izplūst baseinā. Ūdens izsmidzināšanas intensitāte tiek regulēta. Par šīs iekārtas trūkumu var uzskatīt cauruļu sistēmas, kura padod skābekli un ūdeni, masīvumu un dārdzību, kā arī ūdens spiediena radīšanas enerģijas patēriņa nepieciešamību.The closest analogue of the present invention is an oxygen saturation apparatus 30 (EP1094701), which is implemented as a floating apparatus above the pool closed with a hermetic dome. The airtight dome is filled with oxygen, but inside it pressurized water is sprayed, which mixes with oxygen. The oxygen-saturated water then flows into the pool. The water spray rate is regulated. The drawback of this unit can be considered the bulk and costly nature of the piping system, which supplies oxygen and water, as well as the energy consumption of the water pressure.
Piedāvātais izgudrojums atrisina zivju dzīvībai svarīgu problēmu, kas ir optimāls ar skābekli piesātināts ūdens zivju audzēšanas baseinā un samazināts enerģijas patēriņš 5 ūdens pārsūknēšanai un sarežģītas iekārtas izveidošanai, šajā nolūkā ūdens plūsma, kas ieplūst no attīrīšanas bloka, kurā uzbūvē ir nostādinātājs, mehāniskās attīrīšanas filtrs un biofiltrs, piesātina tiešā mijiedarbībā (barbotēšana) ar skābekļa plūsmu no oksigenātora īscaurules skābekļa pievadīšanai, bet pēc tam sajauc skābekli ar izsmidzināmu krītoša ūdens plūsmu, kuru virza virs zivju audzēšanas baseina novietota groza ar plastmasas 10 pildvielu.The present invention solves an important fish life problem that is optimized by oxygenated water in a fish farming basin and reduced energy consumption for pumping water and creating a sophisticated plant by means of a stream of water flowing from a settling unit, mechanical purification filter and biofilter, saturates in direct interaction (bubbling) with oxygen flow from the oxygenator for the oxygen delivery, and then mixes the oxygen with a spray water stream sprayed through a basket filled with plastic 10 fillers placed above the fish farming basin.
Šī paņēmiena realizēšanai ūdens plūsmas' ieejā no attīrīšanas bloka virs zivju audzēšanas baseina veido kameru, kura no augšas nosegta ar hermētisku apvalku ar tajā uzstādītu oksigenātora īscauruli skābekļa pievadīšanai, bet no apakšas ierobežo Z-veida plātne, kurai piestiprina izveidotu tīklveida grozu ar plastmasas pildvielu, noslēgtu ar 15 perforētu plāksni. Perpendikulāri pie plāksnes uzstāda ūdens plūsmu ierobežojošu vertikālu sienu.To accomplish this technique, the water flow at the entrance of the purification unit above the fish breeding basin is formed by a chamber sealed from above with an oxygenator conduit fitted thereon, but at the bottom bounded by a Z-shaped plate fitted with a plastic mesh basket closed with 15 perforated plates. A vertical wall limiting water flow is installed perpendicular to the slab.
Grozu ar plastikāta pildvielu var pievienot tieši atdalošajai sienai starp attīrīšanas bloku un zivju audzēšanas bloku, turklāt hermētiskais apvalks jāizvieto virs ūdens plūsmas no attīrīšanas bloka zivju audzēšanas baseinā, un papildus tajā var uzstādīt 20 ultravioleto lampu.The plastic filler basket can be attached directly to the separating wall between the purification unit and the fish farming unit, whereby the airtight shell should be placed above the water flow from the purification unit in the fish farming basin and additionally equipped with 20 ultraviolet lamps.
Piedāvātā izgudrojuma atšķirīgā īpatnība ir vienlaicīga ūdens plūsmas barbotēšana ar skābekli un lielas platības skābekļa un ūdens mijiedarbības nodrošināšana, bet pēc tam, radot lietus efektu, ūdens un skābekļa sajaukšana, izsmidzinot skābekli ūdens plūsmu, kura tek cauri plastmasas pildvielai.A distinctive feature of the present invention is the simultaneous bubbling of a stream of oxygen with oxygen and the provision of a large area of oxygen-water interaction, followed by a mixture of water and oxygen by spraying a stream of oxygen through a plastic filler to produce a rain effect.
Šo paņēmienu realizējošā iekārta ir kamera ūdens piesātināšanai ar skābekli, kura ir segta ar hermētisku apvalku ar tajā uzstādītu oksigenātora īscauruli skābekļa pievadīšanai un no apakšas, ierobežota ar Z-veida plātni, kurai ir piestiprināts tīklveida grozs ar plastmasas pildvielu. Grozs ar plastmasas pildvielu novietots tādā veidā, ka starp hermētisko apvalku, groza ar plastmasas pildvielu sienām un zivju audzēšanas baseina ūdens virsmu izveidota telpa, kura pildīta ar skābekli.The apparatus implementing this technique is an oxygen saturation chamber covered by an airtight sheath with an oxygenator conduit for insertion of oxygen into the bottom and bounded at the bottom by a Z-shaped plate fitted with a mesh basket with a plastic filler. The basket with the plastic filler is placed such that an oxygen filled space is created between the airtight shell, the plastic filler walls and the water surface of the fish farming basin.

Kā viens no izgudrojuma īstenošanas paņēmieniem var būt šāds:One embodiment of the invention may include the following:
Pēc mehāniskās filtrācijas un bioloģiskās attīrīšanas, ūdens plūsma no attīrīšanas bloka tiecas uz zivju audzēšanas baseinu pāri atdalošajai sienai, virs kuras novietota ultravioleto staru lampa. (Tiek izmantota ultravioleto staru lampa ar jaudu 135 W un UV starojuma devu 50 000 pWs/cm2, bet plūstošā ūdens slānis virs atdalošas sienas ir 23 cm). Attīrīts un dezinficēts ūdens, kurā skābekļa saturs ir ne vairāk ka 90 %, vispirms ieplūst skābekļa piesātināšanas kamerā, kurā no izvietotas zem hermētiskā apvalka oksigenātora īscaurules ienāk tīra gāzveidīga skābekļa strūkla ar spiedienu 0,1-0,2 bārs. Skābeklis, barbotējot, mijiedarbojas ar ūdens virsmas slāni, līdz ar ko skābekļa piesātinājums pārsniedz 100%. Skābeklis vienlaikus izklīst visā telpā zem hermētiskā apvalka, bet ūdens plūsma tiek virzīta caur grozu ar plastmasas pildvielu un, plūstot cauri, ūdens tiek izsmidzināts sīkas urdzēs un pilienos, kuri, krītot, tiek sajaukti ar skābekli. Skābeklis šķīst ūdenī. Tad ūdens, piesātināts ar skābekli, kurā piesātinājums sasniedz 200-300 %, pilienu veidā iekļūst zivju audzēšanas baseinā.After mechanical filtration and biological purification, the flow of water from the purification unit tends to the fish farming basin over a partition wall above which an ultraviolet lamp is placed. (An ultraviolet lamp with a power of 135 W and a UV dose of 50 000 pWs / cm 2 are used , but the layer of flowing water above the separation wall is 23 cm). Purified and disinfected water, containing up to 90% oxygen content, first enters an oxygen saturation chamber where a stream of pure gaseous oxygen at a pressure of 0.1-0.2 bar enters the oxygenator conduits under the sealed housing. Oxygen, when bubbling, interacts with the surface layer of the water, resulting in oxygen saturation greater than 100%. At the same time, oxygen is dispersed throughout the room under an airtight shell, but the water flow is passed through a basket of plastic filler and, when flowing through, water is sprayed into tiny cavities and droplets, which when mixed with oxygen. Oxygen is soluble in water. Then, water saturated with oxygen, where the saturation reaches 200-300%, enters the fish farming basin in drops.
Piedāvātais paņēmiens un iekārta, ar kuru palīdzību paņēmiens tiek realizēts, ir ekonomiska alternatīva zināmiem energoietilpīgiem paņēmieniem ūdens piesātināšanai ar skābekli zivju audzēšanas baseinā. Tie neprasa ne jaudīgu energoietilpīgu sūkņu uzstādīšanu ūdens pārsūknēšanai vai spiediena radīšanu skābekļa vai ūdens izsmidzināšanai, ne cauruļvadu sistēmas ierīkošanu, kas nodrošinātu apakšzemes skābekļa rezervuāru izmantošanu. Ūdens piesātināšana ar skābekli notiek dabīgi un 10 vienmērīgi, tiek nodrošināts pastāvīgs ūdens piesātināšanas ar skābekli līmenis, kas nepieciešams zivju spējai funkcionēt un to intensīvai attīstībai. Paņēmiens un iekārta ir lēti izpildei un ekonomiski izdevīgi ekspluatācijā.The proposed process and the apparatus by which the process is carried out are an economical alternative to known energy intensive techniques for oxygenation of water in a fish farming basin. They do not require either the installation of powerful, energy-intensive pumps for pumping water or the creation of pressure for spraying oxygen or water, nor the installation of a piping system that provides for the use of underground oxygen tanks. Oxygen saturation of water occurs naturally and evenly, providing a constant level of oxygen saturation, which is necessary for the fish to function and develop intensively. The technique and equipment are inexpensive to execute and cost effective to operate.
