Goščni in oljni separator za odpadne vodeWastewater and oil sewage separators
Izum se nanaša na goščni in oljni separator za odpadne vode z odlagalnim prostorom, ki tvori lovilnik za goščo za odpadno vodo, ki se dovaja prek dotoka odpadne vode, s ploščno ločilno napravo, priključeno na komoro za separiranje olja, ta naprava pa je sestavljena iz nagnjenega tokovnega kanala, ki se dviguje v smeri toka, z več ločilnimi ploščami, razvrščenimi v medsebojnem razmaku in vzporednimi na tok ter z odtokom za odpadno vodo, ki smo jo v komori za separiranje olja očistili olja.The invention relates to a sludge and oil wastewater separator with a storage compartment forming a wastewater sludge trap, which is supplied via a wastewater inlet, with a plate separating device connected to an oil separation chamber, this device comprising of an inclined upward flowing channel with several separating plates arranged in parallel and parallel to the flow and with the waste water outlet which the oils were cleaned in the oil separation chamber.
Da bi zagotovili prednostne pogoje separacije za tovrstni goščni in oljni separator, je poznano, (AT 405 066 B) da cilindrični prestrezalni bazen predelimo v prostor za grobo separiranje, ki tvori lovilnik za goščo, in prostor za fino separiranje, ki je povezan s prostorom za grobo separiranje prek preliva. Prostor za fino separiranje spet tvori pretočno komoro za separiranje olja in odtočno komoro, ki ima odtok, med komoro in komoro za separiranje olja pa je nameščena ploščna ločilna naprava v obliki tokovnega kanala, nagnjenega navzdol v smeri toka z več ločilnimi ploščami, nameščenimi druga nad drugo in vzporednih s tokom. Ploščno ločilno napravo vstavimo kot prefabricirano gradbeno enoto v odprtino za prestrezanje v delilni steni, ki deli prostor za fino separiranje v komori za separiranje olja in odtočno komoro. Medtem ko odpadna voda teče iz komore za separiranje olja med poševno navzdol potekajočimi ločilnimi ploščami ploščne ločilne naprave v odtočno komoro, se ostanki olja zbirajo na gornjih parih plošč, ki vsakič omejujejo izstopanje pretoka, medtem ko se delci trdnih snovi, ki jih tok nosi s sabo glede na težo, potopijo proti spodnji ločilni plošči in izpraznijo z odpadno vodo v odtočno komoro. Oljni delci potujejo nazaj proti toku navzgor v komoro za separiranje olja, kjer se združijo z naplavljenim oljnim slojem na odpadni vodi. Odpadna voda očiščena olja in gošče se dvigne v odtočno komoro in odteče nad odtokom, medtem ko se naplavljeno olje iz komore za separiranje olja in iz prostora za grobo separiranje, ki je povezan s komoro za separiranje olja s pretokom, občasno izprazni. S predelitvijo ločilnega bazena v prostor za grobo separiranje in fino separiranje ter prostora za fino separiranje v komoro za separiranje olja in odtočno komoro, s tem povezan konstrukcijski strošek s temi znanimi separatorji za goščo in olje ni velik.In order to provide preferential separation conditions for this slurry and oil separator, it is known (AT 405 066 B) that the cylindrical interceptor pool is converted into a coarse separating space forming a slurry trap and a finely separating space associated with the space for rough separation over dressing. The fine separation compartment again forms an oil separating flow chamber and a drainage chamber having an outlet, and a plate-shaped downstream device is arranged between the chamber and the oil separation chamber, downstream with several separation plates positioned second above second and parallel to the current. The plate separating device is inserted as a prefabricated building unit into the intersection opening in the partition wall, which divides the space for fine separation in the oil separation chamber and the drainage chamber. As the waste water flows from the oil separation chamber between the slanting downstream separating plates of the plate separating device into the drainage chamber, oil residues are collected on the upper pairs of plates, each limiting the discharge of the flow, while the solids particles carried by the stream with by weight, they are immersed against the lower separator plate and emptied with wastewater into a drainage chamber. The oil particles travel back upstream to the oil separation chamber, where they merge with the deposited oil layer on the waste water. The waste water of the purified oil and sludge is lifted into the drainage chamber and drained over the drain, while the drained oil from the oil separation chamber and from the coarse separation room connected to the oil separation chamber by the flow is periodically emptied. By transferring the separation basin into a coarse separation and fine separation space and a fine separation space into the oil separation chamber and the drainage chamber, the associated construction cost with these known sludge and oil separators is not large.
Za ločevanje lebdečih delcev iz odpadnih voda je poznana (DE 42 31 790 A1) ploščna ločilna naprava s kanalom za pretok, ki se dviga v smeri toka, ta kanal pa je razdeljen z več ločilnimi, s tokom vzporednimi ploščami, v delne kanale, ki so razvrščeni eden poleg drugega, tako da se lebdeči delci in delci umazanije ločijo v nasprotni smeri toka v posameznih delnih kanalih in se odložijo v sprejemni posodi v ploščni ločilni napravi. Posoda, ki jo lahko uporabimo v ploščni lovilni napravi, predstavlja ločeno gradbeno enoto, na katero nad pretokom na eni strani priključimo separator za olje, na drugi strani pa koalescenčni separator, kar prinaša večji strošek vgradnje ter potreben ustrezen prostor.For the separation of suspended particulates from wastewater, (DE 42 31 790 A1) is known a plate separating device with a flow channel rising in the direction of flow, and this channel is divided by several separating, flow-parallel plates into partial channels which are arranged side by side so that the suspended particles and dirt particles are separated in the opposite direction of flow in the individual partial channels and deposited in the receiving vessel in the plate separating device. The container, which can be used in a plate trap, is a separate building unit, to which an oil separator is connected above the flow, and a coalescent separator on the other, which results in a higher installation cost and the required space.
Cilj izuma je torej oblikovati tak goščni in oljni separator za odpadne vode, ki bo že na začetku oblikovan tako, da bo konstrukcija bistveno poenostavljena, ne da bi se morali bati, da bo ovirano delovanje separiranja.It is therefore an object of the invention to provide such a sludge and oil separator for waste water, which will be initially designed in such a way that the construction will be substantially simplified, without having to fear that the operation of the separation will be impeded.
S tem izumom je zastavljena naloga rešena tako, da komora za separiranje olja predstavlja vstavek prostora za odlaganje nad lovilnikom gošče, da je med odlagalnim prostorom in komoro za separiranje olja nameščena ploščna ločilna naprava in da je odtok v pretočni povezavi z dnom komore za separiranje olja.The present invention solves the object of the invention by means of an oil separating chamber being an insertion of a storage compartment above the slurry trap, a plate separating device between the depositing space and an oil separating chamber, and the outlet being in flow connection with the bottom of the oil separating chamber .
Ker je zaradi teh ukrepov potreben samo še en vstavek za odlagalni prostor - ki je priključen na odtok in služi kot komora za separiranje olja - v katerega speljemo odpadno vodo za separiranje gošče in olja, se izkažejo posebno preprosta konstrukcijska razmerja, zlasti ker je vstavek treba vstaviti zgolj kot prefabricirano gradbeno enoto v posodo, ki predstavlja odlagalni prostor. Z vgradnjo komore za separiranje olja nad lovilnikom za goščo, ki se nahaja v dnu odlagalnega prostora, odlaganje trdih delcev ni ovirano zaradi toka odpadne vode iz odlagalnega prostora v komoro za separiranje olja. Voda, ki teče navzgor skozi ločilne plošče ploščne ločilne naprave v komori za separiranje olja, podpira sojemanje olja v komoro za separiranje olja, medtem ko prineseni trdi delci potonejo zaradi težnosti proti spodnji ločilni plošči vseh parov plošč, prek katerih teče tok, in zaradi manjše hitrosti pretoka v območju plošč zopet potonejo v nasprotni smeri toka vzdolž ločilnih plošč v odlagalni prostor. Vsekakor se lahko drobnozrnati ostanki trdih delcev, ki zaidejo v komoro za separiranje olja, odložijo v komori za separiranje olja. Zato je treba poskrbeti samo za to, da je odtok priključen pod naplavljenim oljnim slojem na komori za separiranje olja, da bi dobili konstrukcijsko preprost, funkcionalno varen in učinkovit separator za goščo in olje.As these measures require only one additional insert for the storage compartment - which is connected to the drain and serves as an oil separation chamber - into which the waste water is discharged to separate the sludge and oil, particularly simple structural relationships are shown, especially since the insert has to be Only be inserted as a prefabricated building unit into a container that represents a storage compartment. By installing an oil separation chamber above the sludge trap located at the bottom of the storage compartment, the deposition of particulate matter is not impeded by the flow of wastewater from the deposition compartment into the oil separation chamber. Water flowing up through the separation plates of the plate separating device in the oil separation chamber supports the intake of oil into the oil separation chamber, while the solids brought in are sinking due to gravity towards the lower separation plate of all pairs of plates through which the flow flows and due to the smaller the flow velocities in the region of the plates again sink in the opposite direction of flow along the separating plates into the storage compartment. In any case, the fine-grained residues of solids that enter the oil separation chamber may be deposited in the oil separation chamber. Therefore, care should only be taken to ensure that the drain is connected underneath the flooded oil layer on the oil separation chamber to obtain a structurally simple, functionally safe and efficient sludge and oil separator.
Čeprav lahko ploščno ločilno napravo vstavimo v obodno steno komore za separiranje olja, se izkažejo za kar najbolj kompaktno gradbeno enoto vstavka še posebno prednostna konstrukcijska razmerja, če je ploščna ločilna naprava vstavljena v dno komore za separiranje olja. V dnu komore za separiranje olja je poleg dela, ki štrli v komoro za separiranje olja ploščne ločilne naprave pomirjeno območje, iz katerega prednostno vodimo odpadno vodo v odtok. V ta namen bi lahko komoro za separiranje olja ločili od iztoka s potopno steno. Vendar pa dobimo preprostejše konstrukcijske pogoje, če odtok povežemo s komoro za separiranje olja s potopno cevjo.Although a panel separator can be inserted into the circumferential wall of the oil separator chamber, design ratios are particularly advantageous if the plate separator is inserted into the bottom of the oil separator chamber. In the bottom of the oil separation chamber, in addition to the part projecting into the oil separation chamber of the plate separating device, is a reconciled area from which waste water is preferably discharged into the drain. For this purpose, the oil separation chamber could be separated from the outlet by a submersible wall. However, simpler design conditions are obtained if the drain is connected to an oil separation chamber with a submersible tube.
Na sliki je predmet izuma predstavljen na primeru. Slike prikazujejo:The invention is illustrated by way of example. Pictures show:
sl. 1 goščni in oljni separator za odpadne vode v smislu izuma v poenostavljenem osnem prerezu in sl. 2 isti separator v shematskem prerezu po črti II-II slike 1.FIG. 1 shows a slurry and oil separator for waste water according to the invention in a simplified axial section and FIG. 2 is the same separator in schematic section along line II-II of Figure 1.
Goščni in oljni separator v smislu predstavljenega izvedbenega primera predstavlja cilindrično posodo 2, izdelano iz betona, ki je nameščena na podstavek 1, in nosi pokrov 3 z dvema dovodnima odprtinama 4 in 5. Na dotok 6 odpadne vode, ki se nahaja na steni posode, je priključen dotočni ventil 8, ki se zapira s plovcem 7, ventil pa zapre dotok 6 odpadne vode, ko naplavljeni oljni sloj preseže določeno višino na odpadni vodi v posodi 2.The slurry and oil separator in the present embodiment represents a cylindrical container 2 made of concrete, which is mounted on a pedestal 1, and carries a lid 3 with two inlet openings 4 and 5. To the inlet 6 of the waste water located on the wall of the container, an inlet valve 8 is connected, which closes with the float 7, and the valve closes the inlet 6 of the wastewater when the accumulated oil layer exceeds a certain height on the wastewater in the vessel 2.
Posoda 2 predstavlja za dovajano odpadno vodo odlagalni prostor 9, ki v območju dna predstavlja lovilnik 10 za goščo. V odmiku nad tem lovilnikom 10 za goščo je v območju dovodne odprtine 5 predviden vstavek 11, ki v bistvu prevzema komoro 12 za separiranje olja, ki je ločena iz odlagalnega prostora 9, ta komora pa je povezana z odlagalnim prostorom 9 s ploščno ločilno napravo 13. Ta ploščna ločilna naprava 13 je sestavljena iz vzporednih, eno za drugo nameščenih ločilnih plošč 14, ki med seboj omejujejo izstope 15 pretoka. Kot lahko vidimo na sliki 1, tvorijo ti izstopi 15 pretoka predeljeni pretočni kanal 17, ki je nagnjen navzgor od dna 16 komore 12 za separiranje olja, kanal pa vodi pod tem odtokom 18 za odpadno vodo, očiščeno gošče in olja v komoro 12 za separiranje olja. Ta odtok 18 je priključen na potopno cev 19 v komori 12 za separiranje olja, ki se stransko poleg ploščne ločilne naprave 13 razširi proti dnu 16 komore 12 za separiranje olja.The container 2 represents a storage compartment 9 for the wastewater supply, which in the area of the bottom represents a sludge trap 10. In the distance above this sludge trap 10, an insert 11 is provided in the area of the inlet opening 5, which essentially takes over the oil separation chamber 12, which is separated from the storage compartment 9, and this chamber is connected to the storage compartment 9 by a plate separating device 13 This plate separating device 13 consists of parallel, one after the other, separating plates 14 that limit the projections 15 of the flow. As can be seen from Figure 1, these outlets 15 of the flow form a divided flow channel 17, which slopes upwards from the bottom 16 of the oil separation chamber 12, and the channel leads below that outlet 18 for waste water, cleaned sludge and oil to the separation chamber 12 oils. This drain 18 is connected to a submersible pipe 19 in the oil separation chamber 12 which extends laterally to the bottom of the plate separation device 13 towards the bottom 16 of the oil separation chamber 12.
V odlagalnem prostoru 9 posode 2 se potopijo trdi delci odpadne vode, ki priteče prek dotoka 6 odpadne vode v območje lovilnika 10 za goščo, medtem ko se del olja, ki pride z odpadno vodo, naplavi in tvori na gladini 20 odpadne vode oljni sloj 21. Z dovajano odpadno vodo se del odpadne vode spodrine iz odlagalnega prostora 9 prek ploščne ločilne naprave 13 v komoro 12 za separiranje olja, pri čemer je v izstopih 15 pretoka med vsakima dvema ločilnima ploščama 14 podprto ločevanje preostalega olja in še ne odloženih, drobnozrnatih trdih delcev. Ostanki olja, ki se pojavijo znotraj delnih pretokov odpadne vode, se potem zbirajo vzdolž gornje ločilne plošče 14, medtem ko trdi delci iz delnih, navzgor usmerjenih pretokov, potujejo proti spodnji ločilni plošči 14. Ostanki olja, ki se zbirajo v območju gornjih ločilnih plošč 14 izstopov 15 pretoka, se izločijo v smeri toka odpadne vode v komoro 12 za separiranje olja in tvorijo v komori 12 za separiranje olja oljni sloj 22, medtem ko trdi delci, ki se zbirajo v območju spodnjih ločilnih plošč, potonejo v smeri toka v odlagalni prostor 9 zaradi težnosti. Količina odpadne vode, ki priteče v komoro 12 za separiranje olja, spodrine del očiščene odpadne vode iz potopne cevi 19 v odtok 18, od koder odteče očiščena odpadna voda. Na sliki 1 so z ustreznimi puščicami, ki prikazujejo tok vode, prikazane bistvene poti pretoka skozi ploščno ločilno napravo 13 in komoro 12 za separiranje olja. Prek dovodnih odprtin 4 in 5 pokrova 3 posode lahko odstranimo nabrani oljni sloj 21 oz. 22. Skozi ti dovodni odprtini 4 in 5 je mogoč tudi izpust gošče.In the storage compartment 9 of the vessel 2, solid particles of wastewater are introduced, which flows through the inlet 6 of the wastewater into the area of the sludge trap 10, while the part of the oil that comes with the wastewater floats and forms an oil layer at the wastewater surface 20. With the effluent inlet, a portion of the wastewater is forced out of the storage compartment 9 through a plate separating device 13 into an oil separation chamber 12, with the separation of residual oil and not yet deposited, fine-grained, solid residues in the outlets 15 between each of the two separation plates 14. particles. The oil residues that occur within the partial effluent flows are then collected along the upper separation plate 14, while the solid particles from the partial upstream flows travel towards the lower separation plate 14. The oil residues collected in the area of the upper separation plates 14 outlets 15 of the flow are discharged in the direction of the waste water into the oil separation chamber 12 and form an oil layer 22 in the oil separation chamber, while the solid particles collected in the area of the lower separating plates sink in the direction of flow into the deposition chamber space 9 due to gravity. The amount of wastewater flowing into the oil separation chamber 12 discharges a portion of the treated wastewater from the submersible pipe 19 into the outlet 18, from which the treated wastewater flows. In Fig. 1, the corresponding arrows showing the flow of water show the essential flow paths through the plate separation device 13 and the oil separation chamber 12. Through the inlet openings 4 and 5 of the lid 3 of the container, the accumulated oil layer 21 or 16 can be removed. 22. Through these feed holes 4 and 5 it is also possible to discharge the slurry.
