Description

DK 157249 BDK 157249 B

Opfindelsen angâr en udskiller, fortrinsvis til udskillelse af olie og sand fra afl0bsvand, omfattende en genneml0bsbr0nd med et till0b og et afl0b og, i str0mnings-banen mellem till0bet og afl0bet, et systera af et eller 5 flere præfabrikerede moduler af pladeknipper, som er skrât-stillede i forhold til lodret plan, og som bar indbyrdes mellemrum og ligger parallelt med hinanden og med gennem-str0mstr0mningsretningen for br0nden.The invention relates to a separator, preferably for separating oil and sand from effluent, comprising an inlet well having an inlet and an outlet and, in the flow path between the inlet and the outlet, a system of one or more prefabricated modules of slab cut -posed relative to the vertical plane, which were spaced apart and lying parallel to each other and with the flow direction of the well.

Udskillelsen i en sâdan udskiller sker ved tværse-10 dimentation, benboldsvis tværflotation.The separation in such a separator occurs by cross-sedimentation, bone-ball cross-flotation.

Udskillere af ovennnævnte art er kendt bâde som stationære anlæg nedgravet i jorden og som oven pâ jorden anbragte præfabrikerede tanke og udmærker sig ved en vae-sentlig st0rre udskillelsesevne i forhold til klarings-15 tanke, der blot er udstyret med forskellige former for lod-rette skillevægge til tilbageholdelse af udskilte medier i tanken. Denne st0rre udskillelsesevne ved hjælp af skrât-stillede plader beror pâ, at lettere bestanddele i væsken, sâsom olie, fâr mulighed for at stige op mod overfladen, og 20 tungere bestanddele, sâsom sand, fâr mulighed for at falde til bunds i tanken, idet stigh0jder, henholdsvis falddybder reduceres til den lodrette afstand mellem de skrâtstillede plader eller lameller.Precipitators of the above-mentioned type are known both as stationary systems buried in the ground and as prefabricated tanks placed on the ground and distinguish themselves by a significantly greater separability compared to clearing tanks which are simply equipped with different types of vertical partitions for retaining separated media in the tank. This greater separability by means of inclined plates is due to the fact that lighter constituents in the liquid, such as oil, are allowed to rise to the surface, and 20 heavier constituents, such as sand, are allowed to fall to the bottom of the tank, as pitch heights or drop depths, respectively, are reduced to the vertical distance between the inclined plates or slats.

Skrâtstillingen af pladerne medf0rer, at opstigende 25 oliedrâber og nedfaldende sandkorn under hèle deres bevæg-else henholdsvis op mod væskeoverfladen og ned mod bunden befinder sig i grænselag og ikke har tilb0jelighed til at-ter at opfanges og medtages af den gennemstr0mmende væske.The slanting of the plates results in ascending oil drops and falling sand grains during their entire movement up to the liquid surface and down to the bottom, respectively, in boundary layers and not inclined to be captured and included by the flowing liquid.

Det er praksis, at ogsâ almindeligt regnvand fra by-30 omrâder udledes til recipientsystemer efter passage af sandfang og olieudskillere for at formindske forureningen af en récipient.It is the practice that even ordinary rainwater from urban areas is discharged into recipient systems after passage of sand traps and oil separators to reduce the pollution of a recipient.

Da de kendte specialbyggede udskilletanke med plade-systemer er forholdsvis komplicerede og kostbare, er de 35 hidtil kun anvendt til specialopgaver, sâsom til rensning af afl0bsvand fra industrianlæg etc., medens de til trodsSince the known custom-built separation tanks with plate systems are relatively complicated and expensive, they have so far been used only for special tasks, such as for the purification of wastewater from industrial plants, etc.

DK 157249 BDK 157249 B

2 for deres âbenbare fordele ikke har fundet anvendelse i al-mindelighed, sâsom ved bundfældingstanke pâ renseanlæg og til rensning af regnvand.2 for their obvious advantages have not been used in general, such as for settling tanks in wastewater treatment plants and for the purification of rainwater.

Opfindelsen tilsigter derfor at tilvejebringe en ud-5 skiller, der kan im0dekomme de stigende krav til rensning af afl0bs- og spildevand.The invention therefore aims to provide a separator that can meet the increasing requirements for wastewater and wastewater treatment.

Dette opnâs ved, at br0nden er forsynet med to lod-rette skillevægge, der sammen med br0ndens væg danner ind-10bs- og udl0bskamre, der strækker sig op over pladeknip-10 perne og op til till0bet og afl0bet, og at skillevæggene har rektangulære indl0bs- og udl0bsâbninger svarende til oirikredsen af pladeknippernes ender og placeret ud for pla-deknippernes ender.This is achieved by providing the well with two vertical partitions which together with the wall of the well form in-10bs and outlet chambers extending up to the plate clips 10 up to the inlet and outlet, and the dividers have rectangular inlets - and outlet openings corresponding to the outer circle of the ends of the plate cutters and located at the ends of the plate cutters.

Med en kombination af gængse br0ndtyper og opbyg-15 ningen af et skrâtstillet pladesystem ved hjælp af præfrem-stillede moduler, som kan nedf0res gennem br0ndenes stand-ardâbninger og monteres nede i br0ndene med simple midler, fas en bâde billigere og bedre sand- og olieudskiller med de deraf f01gende milj0mæssige fordele. Modulerne kan sâle-20 des monteres i eksisterende br0nde uden st0rre omkostnin-ger og kan til enhver tid udskiftes uden arbejdskrævende opgravninger.With a combination of conventional well types and the construction of an inclined plate system by means of prefabricated modules, which can be fed through the standard openings of the wells and fitted down into the wells with simple means, both cheaper and better sand and oil separators are phased in with the resulting environmental benefits. The modules can thus be mounted in existing wells without much cost and can be replaced at any time without labor-intensive excavations.

En simpel udforming af et modul kan if01ge opfindel-se omfatte en eller flere rammer, som omgiver pladebundtet, 25 og de enkelte plader kan være fæstnet i deres 0verste og nederste kanter til rammen eller rammeme.A simple design of a module according to the invention may comprise one or more frames surrounding the plate bundle, and the individual plates may be attached at their upper and lower edges to the frame or frames.

Et modul kan være fremstillet af forskellige materi-materialer, sâsom stâl, métal, plast etc. under den for-udsætning, at materialet i sig selv eller en overfladebe-30 lægning pâ dette er modstandsdygtig overfor de medier, som skal behandles.A module may be made of various material materials, such as steel, metal, plastic, etc. under the condition that the material itself or a surface coating thereon is resistant to the media to be treated.

Pladerne i modulerne kan være plane, let b01gede eller hâve afstivende udtrykninger. Sâdanne b01ger og af-stivningsudtrykninger skal da forl0be pâ tværs af str0m-35 ningsretningen gennem tanken eller br0nden.The plates in the modules can be flat, slightly curved or have stiffening expressions. Such arches and stiffening expressions must then extend across the flow direction through the tank or well.

Opfindelsen forklares nærmere i det f01gende ogThe invention is further explained in the following and

Skrâtstillingen kan f.eks^ være ca. 45°.In FIG. 1, there is shown a plate module 1 consisting of two rectangular frames 2, within and between which contaminated plates or slats are placed in relation to the frame sides. 45 °.

Pladerne er anbragt parallelle og med lige store indbyrdes afstande.The plates are arranged parallel and spaced apart.

Rammerne 2 og pladerne 3 kan være fremstillet af 20 plast, métal eller stâl, som enten i sig selv er korrosi-onsbestandigt overfor den væskesammensætning, der skal be-handles, eller er overfladebehandlet med et materiale, som besidder denne korrosionsbestandighed.The frames 2 and plates 3 may be made of 20 plastics, metal or steel, which are either themselves corrosion resistant to the liquid composition to be treated or are surface treated with a material which possesses this corrosion resistance.

Afhængig af materiale af plader og rammer kan pla-25 derne være fæstnet til rammerne ved limning, lodning eller svejsning og eventuelt med pladekanterne indsat i smâ hak i rammernes inderkanter, som antydet ved 4.Depending on the material of plates and frames, the plates may be attached to the frames by gluing, brazing or welding and optionally with the plate edges inserted into small notches in the inner edges of the frames, as indicated by 4.

4 at de kan passere ned gennem br0ndâbningen, er anbragt oven over 0verste kant af sumpen med pladerne parailelt med gen-nemstr0mningsretningen, f.eks. pâ stænger, der ligger i gennemstr0mningsretningen og er fastgjort til br0ndsiden 5 eller til skillevæggene 11 eller blot lagt pâ 0verste kant af sumpen 10 i fig. 2 og 3.4 that they can pass down through the well opening are positioned above the upper edge of the sump with the plates parallel to the flow direction, e.g. on rods lying in the flow direction and attached to the well side 5 or to the partitions 11 or simply laid on the upper edge of the sump 10 in FIG. 2 and 3.

De f.eks. i fig. 1 viste knaster 23 pâ rammerne 2 er velegnede til at holde modulet 1 pâ plads pâ to stænger anbragt ved modulrammernes nederste hj0rner.They e.g. in FIG. 1 on the frames 2 is suitable for holding the module 1 in place on two bars located at the lower corners of the module frames.

10 I br0nden er der for hver ende af modulsættet 1 an bragt en skillevæg 11, som nâr helt ned til sumpens over-kant, men som er udsparet med en rektangulær âbning 12 svarende til modulrammernes omkreds, som vist i fig. 3.10 In the well, at each end of the module set 1 is provided a partition 11 which extends all the way down to the top of the sump, but which is recessed with a rectangular opening 12 corresponding to the circumference of the module frames, as shown in FIG. Third

Skillevæggene 11 deler br0nden i tre kamre, et ind-15 10bskammer 13, et udskillekammer 14 og et udl0bskammer 15.The partitions 11 divide the well into three chambers, an inlet chamber 13, an exclusion chamber 14 and an outlet chamber 15.

Udskillebr0nden virker pâ f01gende mâde.The separation well works in the following way.

Spilde- eller afl0bsvand ledes til br0nden gennem till0bet 8 og tvinges af den f0rste skillevæg 11 nedad i indl0bskammeret 13, ind gennem âbningen 12 i den f0rste 20 skillevæg 11 til plademodulerne 1, gennem disses pladebund-ter og ud gennem âbningen 12 i den i anden skillevæg 11, op gennem udl0bskammeret 15 og ud af afl0bet 9.Wastewater or drainage water is led to the well through inlet 8 and forced by the first partition 11 downwardly into the inlet chamber 13, through the opening 12 of the first 20 partition 11 to the plate modules 1, through their plate bundles and out through the opening 12 of the second partition wall 11, up through the outlet chamber 15 and out of the drain 9.

Ved passagen gennem plademodulerne 1 sker en effek-tiv udskilning af dels lettere, dels tungere bestanddele, 25 sâsom heriholdsvis olie og sand, fra afl0bsvandet. De lettere bestanddele stiger op langs de skrâ plader i modulerne og samler sig 0verst i udskillekammeret 14, medens de tungere synker ned langs pladerne og samler sig i sumpen 10.Passing through the plate modules 1, effective separation of lighter and heavier components, such as oil and sand, from the effluent is effected. The lighter constituents rise along the sloping plates in the modules and accumulate at the top of the separating chamber 14, while the heavier ones sink down along the plates and collect in the sump 10.

Fig. 4 viser anbringelsen af plademoduler i en stan-30 dardbr0nd af st0rre type og opbygget f.eks. af ringe 16 og med plant dæk 17 med en br0ndâbning 18. Denne br0nd adskil-ler sig fra br0nden i fig. 2 og 3 ved, at der er anbragt tre rækker plademoduler 1 med mellemrum ved siden af hinan-den. Hver række kan bestâ af f.eks. tre enkelt-moduler.FIG. 4 shows the arrangement of plate modules in a standard well of a larger type and constructed e.g. of rings 16 and with flat tire 17 with a well opening 18. This well differs from the well of FIG. 2 and 3 know that three rows of plate modules 1 are spaced adjacent to each other. Each row can consist of e.g. three single modules.

35 I hver af skillevæggene 11 er der her tre âbninger 12 svarende til de tre modulrækker.35 In each of the partitions 11 there are three openings 12 corresponding to the three module rows.
