Description
Foreliggende oppfinnelse angår en fremgangsmåte The present invention relates to a method
for avskilling av gassformede forurensinger fra et gassformet medium som inneholder forurensinger, idet mediet under strømmingen oppover i en beholder bringes i berøring med et biologisk høyaktivt produkt, og mediet som er renset avledes oventil i beholderen. for the separation of gaseous pollutants from a gaseous medium that contains pollutants, the medium being brought into contact with a biologically highly active product during the flow upwards in a container, and the medium that has been purified is diverted upwards in the container.
En slik fremgangsmåte er tidligere kjent fra US-patent nr. 3.828.525. Ifølge denne fremgangsmåten anvendes aktivt slam fra. kloakkrenseanlegg for å bryte ned de foruren-sende gassene i det medium som skal renses. Det har nå vist seg at man kan oppnå meget store forbedringer sammenlignet med den kjente metoden dersom man som absorberende materiale anvender en kompost, dvs. et fast produkt oppnådd ved biologisk nedbryting (forråtnelse) av organisk avfall og/eller slam fra kloakkrenseanlegg. Et slikt materiale har vist seg å være meget kraftig absorberende og absorberer således lett forurensningene, slik at den biologiske nedbrytingen kan bringes til å skje effektivt og meget raskt. Ved den biologiske omsettingen oppstår det et forråtnelsestap som i sin tur fører til sammensynking av massen. Det blir således meget lett å kompensere for bruket av absorberende materiale, slik at beholderen alltid kan holdes fylt med det absorberende materiale. Fremgangsmåten ifølge det amerikanske patentet benytter man en oppslamming av biologisk aktivt materiale. Such a method is previously known from US patent no. 3,828,525. According to this method, activated sludge is used from sewage treatment plant to break down the polluting gases in the medium to be cleaned. It has now been shown that very large improvements can be achieved compared to the known method if a compost is used as absorbent material, i.e. a solid product obtained by biological decomposition (rot) of organic waste and/or sludge from sewage treatment plants. Such a material has proven to be very absorbent and thus easily absorbs the pollutants, so that the biological breakdown can be made to take place efficiently and very quickly. During the biological conversion, a putrefactive loss occurs which in turn leads to the mass collapsing. It thus becomes very easy to compensate for the use of absorbent material, so that the container can always be kept filled with the absorbent material. The method according to the American patent uses a slurry of biologically active material.
Det blir da teoretisk umulig ved en kontinuerlig ettrinns-metode fullstendig å skille omsatt materiale fra ikke omsatt. It then becomes theoretically impossible with a continuous one-step method to completely separate reacted material from unreacted material.
På grunnlag av ovenstående karakteriseres derfor den On the basis of the above, it is therefore characterized
innledningsvis angitte fremgangsmåten ved at det som biologisk aktivt produkt benyttes et fra en biologisk forråtnelsesprosess fra organisk avfallsmateriale og/eller klarslam utvunnet, del- initially stated the method in that the biologically active product is used from a biological decay process from organic waste material and/or clear sludge extracted, part-
vis forråtnet kompost, samt at komposten etter lagvis vandring nedover i beholderen utmates fra denne, og at slikt materiale eventuelt blandes med fersk kompost og blandingen tilbakeføres til beholderen oventil i denne. show rotted compost, and that the compost, after moving downwards in layers in the container, is discharged from it, and that such material is possibly mixed with fresh compost and the mixture is returned to the container at the top of this.
Som absorbens tjener en gjennom en lufttilførsel bestyrt forråtnelse av organisk avfall utvunnet kompost, eller også tjener som absorbens en kompost som er utvunnet ved forråtnelse av et klarslam som er blandet med en organisk karbonbærer og styrt over lufttilførselen. For. filterprosessen er det vesentlig dersom kompostens forråtnelse ikke er helt avsluttet. Compost extracted from the decomposition of organic waste controlled through an air supply serves as absorbent, or compost obtained by rotting a clear sludge mixed with an organic carbon carrier and controlled over the air supply serves as absorbent. For. the filter process is essential if the rotting of the compost is not completely finished.
Slike komposteringsmetoder er f.eks. beskrevet i DT-OS 2.252.188 eller i DT-OS 2.253.009. Such composting methods are e.g. described in DT-OS 2.252.188 or in DT-OS 2.253.009.
Det ifølge de nevnte fremgangsmåtene fremstilte filtermaterialet er kraftig blandet med mikroorganismer. Ved innledningen av de for rensing beregnede organiske gassfor-urensningene i beholderen, får de i filtermaterialet tilstedeværende mikroorganismene igjen næring og aktiviseres. I dette biologiskt aktive filtermaterialet skjer det nå en kraftig reaksjon, dvs. en fortsatt forråtnelse og biologisk nedbryting som bevirker at filtermassen synker sammen og må kompletteres med nytt materiale. The filter material produced according to the aforementioned methods is heavily mixed with microorganisms. At the introduction of the organic gas pollutants intended for purification into the container, the micro-organisms present in the filter material are again nourished and activated. In this biologically active filter material, a strong reaction now takes place, i.e. a continued decay and biological breakdown which causes the filter mass to collapse and must be supplemented with new material.
Derved komprimeres det i beholderen tilbakeførte materialet og forandrer sin struktur, noe som er meget for-delaktig for filterprosessen. På grunn av denne såkalte returgodsbearbeidelse er således en gjenvinning av filtermaterialet mulig. Thereby, the material returned to the container is compressed and changes its structure, which is very beneficial for the filter process. Because of this so-called return goods processing, a recycling of the filter material is thus possible.
Fortrinnsvis benyttes en sylindrisk beholder for separering av forurensningene, hvorved de forurensede avgassene bringes til å strømme gjennom absorbenset nedenfra og oppover, samtidig med at absorbenset passerer gjennom beholderen ovenifra og nedover, Den nederste sonen av det ifylte materialet blir utsatt for den største belastningen, Ved hjelp av en utmatningsanordning, fortrinnsvis en ut^ matningéfres, er det mulig etter dnske å utmate alle disse materialene ved beholderens nedre del og ved hjelp av en transportanordning, fortrinnsvis en elevator, å tilbakeføre materialene til beholderens øvre del, der de kan regenereres. Filterprosessen er regulerbar ved endring av gjennom-matningen av absorbens og ved endring av mengden av det nye materiale som skal blandes i. Preferably, a cylindrical container is used for separating the pollutants, whereby the polluted exhaust gases are made to flow through the absorbent from below upwards, at the same time as the absorbent passes through the container from above downwards, The lowest zone of the filled material is exposed to the greatest load, By with the aid of a discharge device, preferably a discharge mill, it is possible to discharge all these materials at the lower part of the container and with the aid of a transport device, preferably an elevator, to return the materials to the upper part of the container, where they can be regenerated. The filter process can be regulated by changing the feed-through of absorbency and by changing the amount of the new material to be mixed in.
Ifølge et ytterligere kjennetegn for oppfinnelsen skal som tilsetningsmiddel bentonittmel settes til absorbenset. According to a further characteristic of the invention, bentonite flour must be added to the absorbent as an additive.
Ved tilsetning av bentonitt dannes i absorbenset stormolekylære forbindelser av leire-humuskompleks. Bentonitt virker i ren tilstand som jonebytter, slik at de i avgassene eller sveveemnene eventuelt tilstedeværende tungtmetalljonene fikseres i vannoppløselig form og visse organiske gassforurens-ninger absorberes av humuskompleksforbindelsene. Tilsetningen av bentonitt har således den fordel at det ved filtreringen dannes leire-humuskompleks, slik at en fiksering og også en omdannelse av forskjellige gassformede organiske forurensninger kan skje over jonebytting eller over komplekse bindinger av tungmetalljoner. When bentonite is added, large molecular compounds of clay-humus complex are formed in the absorbent. In its pure state, bentonite acts as an ion exchanger, so that the heavy metal ions possibly present in the exhaust gases or suspended solids are fixed in a water-soluble form and certain organic gas pollutants are absorbed by the humus complex compounds. The addition of bentonite thus has the advantage that a clay-humus complex is formed during the filtration, so that a fixation and also a transformation of various gaseous organic pollutants can take place via ion exchange or via complex bonds of heavy metal ions.
Ifølge et annet kjennetegn for oppfinnelsen er absorbensets fyllehøyde i beholderen valgt i avhengighet av volumstrømmen av avgassen som skal renses. Absorbensets volum skal således velges i avhengighet av den gassmengde som er aktuell å rense og av forurensningens art og rom-fatning, noe som lett kan fastlåses ved forsøk. According to another characteristic of the invention, the filling height of the absorbent in the container is selected depending on the volume flow of the exhaust gas to be cleaned. The volume of the absorbent must therefore be chosen depending on the quantity of gas to be cleaned and on the nature of the pollution and the size of the room, which can easily be fixed by experiment.
Fremgangsmåten ifølge oppfinnelsen skal i det følgende beskrives nærmere under henvisning til tegningen, der The method according to the invention will be described in more detail in the following with reference to the drawing, where
fig. 1 viser et tverrsnitt gjennom en hensiktsmessig anordning for utførelse av fremgangsmåten, og fig. 1 shows a cross-section through a suitable device for carrying out the method, and
fig. 2 viser et planriss av samme anordning. fig. 2 shows a plan view of the same device.
I en beholder 1, fremstilt som et sylindrisk metall-hus forsynt med et isolasjonslag 2, befinner det seg som absorbens en bylling 3 av biologisk høyaktivt materiale. In a container 1, produced as a cylindrical metal housing provided with an insulation layer 2, there is a bulge 3 of biologically highly active material as absorbent.
Dette består enten av en kompost som er fremskaffet ved av lufttilførselen regulert forråtnelse av organisk avfall, This consists either of a compost that is produced by the rotting of organic waste regulated by the air supply,
eller en kompost som er utvunnet ved forråtnelse av et med en organisk karbonbærer blandet klarslam, der forråtnelsen reguleres av lufttilførselen. Forråtnelsen får imidlertid ikke bli helt avsluttet, for at komposten fortsatt skal være biologisk aktiv. or a compost obtained by rotting a clear sludge mixed with an organic carbon carrier, where the rotting is regulated by the air supply. However, the decomposition must not be completely finished, so that the compost remains biologically active.
Beholderen 1 oppviser en bunnflate som heller svakt inn mot sentrum. Over bunnen er det anordnet en utmatnings-fres 5 som føres rundt bunnen for å få en jevn utmatning av filtermaterialet. Utmatningsfresen drives av en ikke vist drivanordning, som er bevegelig omkring en aksel 6, slik at utmatningsfresen 5 foruten sin egen bevegelse, kan dreies med urviserretningen over beholderens bunn. Utmatningsfresen 5 mater på denne måte ut materialfyllingens 3 underste lag gjennom en åpning 8 i sentrum av beholderens bunn. Det utmatede materialet faller ned på en transportanordning 10 som mater dette i pilens retning til en blander 11 med tilhørende tilførselsanordning 12 for nytt materiale, og en elevator 13. Derved blandes det utmatede materialet med nytt materiale og tilbakeføres til beholderens 1 øvre del, hvorfra det ved hjelp av en fordeler 15 fordeles jevnt over beholderens topp. Container 1 has a bottom surface that slopes slightly towards the centre. A discharge mill 5 is arranged above the bottom, which is guided around the bottom to obtain an even discharge of the filter material. The discharge cutter is driven by a drive device, not shown, which is movable around a shaft 6, so that the discharge cutter 5, in addition to its own movement, can be rotated clockwise over the bottom of the container. In this way, the discharge cutter 5 feeds out the bottom layer of the material filling 3 through an opening 8 in the center of the bottom of the container. The discharged material falls onto a transport device 10 which feeds it in the direction of the arrow to a mixer 11 with associated supply device 12 for new material, and an elevator 13. The discharged material is thereby mixed with new material and returned to the upper part of the container 1, from where it by means of a distributor 15 is distributed evenly over the top of the container.
Over en ikke vist vifte og et rørledningssystem 17 innledes de avgassene som skal renses eller den luften som skal renses i beholderens bunnområde gjennom et antall munnstykker 18. Beholderen 1 er åpen oventil, slik at de nedenfra i pilens retning innførte avgassene må strømme opp gjennom den i beholderen synkende fylling av filtermaterialet, og renses ved absorpsjon og biologisk omsetting med dette. Denne absorpsjon og biologiske omsetting er biologiske prosesser, slik at det på denne måte opptrer en forråtnelsesprosess i filterfyllingen, som leder til forråtnelsestap. Dette tapet ytrer seg i en sammensynkning av fyllingen som stadig erstattes ved tilførsel av nytt materiale over innmatningsanordningen 12, slik at beholderen 1 hele tiden er fullstendig fylt med filtermaterialet. Alt etter avgassforurensningenes volum og styrke kjøres beholderen langsomt eller raskere i sirkulasjonen eller innmatningen, dvs. gjennommatingen av filtermaterialet retarderes eller aksellereres. Ettersom avgassene alltid strømmer nedenfra og oppover, blir det underste filterlaget alltid kraftigst belastet. Da imidlertid filtermaterialet mates ut på dette sted og det utmatede materialet blandes med nytt materiale, får det uttatte filtermaterialet på sin vei gjennom beholderen tid til å undergå regenerering. Etter en bestemt tid må naturligvis hele filtermaterialet erstattes med nytt. Det utmatede filtermaterialet egner seg bra som jordforbedringsmiddel. Above a fan (not shown) and a pipeline system 17, the exhaust gases to be cleaned or the air to be cleaned are introduced into the bottom area of the container through a number of nozzles 18. The container 1 is open at the top, so that the exhaust gases introduced from below in the direction of the arrow must flow up through the in the container descending filling of the filter material, and is cleaned by absorption and biological conversion with this. This absorption and biological conversion are biological processes, so that in this way a decay process occurs in the filter filling, which leads to decay losses. This loss manifests itself in a collapse of the filling which is constantly replaced by the supply of new material via the feeding device 12, so that the container 1 is always completely filled with the filter material. Depending on the volume and strength of the exhaust gas contaminants, the container is driven slowly or faster in the circulation or feed, i.e. the feed through of the filter material is slowed down or accelerated. As the exhaust gases always flow from below upwards, the lowest filter layer is always heavily loaded. However, when the filter material is fed out at this location and the fed out material is mixed with new material, the withdrawn filter material is given time to undergo regeneration on its way through the container. After a certain time, the entire filter material must of course be replaced with new. The discharged filter material is suitable as a soil conditioner.
Dersom de avgassene som skal renses krever dette, blandes filtermaterialet over innmatningsanordningen 12 dess-uten med bentonittmel, hvis dosering kan bestemmes på grunnlag av enkle forsøk. If the exhaust gases to be cleaned require this, the filter material above the feed device 12 is additionally mixed with bentonite flour, the dosage of which can be determined on the basis of simple experiments.
Beholderen 1 rommer et volum på ca. 10 - 200 m^, fortrinnsvis omkring 50 m~*. Volumet velges avhengig av den ut-viklede gassmengden og forurensningenes art og mengde. Dette gjelder også for størrelsen for utmatningen og tilførselen av nytt materiale, som likeledes beror på den gassmengde som skal sendes gjennom filteret og forurensningenes art og mengde. Container 1 holds a volume of approx. 10 - 200 m^, preferably around 50 m~*. The volume is chosen depending on the amount of gas evolved and the nature and quantity of the contaminants. This also applies to the size of the output and supply of new material, which likewise depends on the amount of gas to be sent through the filter and the nature and quantity of the contaminants.
I prinsipp er det mulig ikke i det hele tatt å innblande noe nytt materiale, eller en liten eller en stor mengde. Filter-anordningens effektivitet kan fastslås ved hjelp av ikke viste målesonder og filterprosessen reguleres ved endring av den gjennommatede mengden av filtermaterialet og tilsetning av nytt filtermateriale. Over transportøren 10 kan forbrukt materiale utmates ved 20. In principle, it is possible not to mix in any new material at all, or a small or a large amount. The effectiveness of the filter device can be determined using measuring probes not shown and the filter process is regulated by changing the amount of filter material fed through and adding new filter material. Above the conveyor 10, consumed material can be discharged at 20.
Et eksempel på bruk av prosess er følgende: Avløpsluft fra en penicillinfabrikk skal renses for biostøv. An example of the use of a process is the following: Waste air from a penicillin factory is to be cleaned of biodust.
Denne gassen inneholder følgende forurensninger This gas contains the following contaminants
Den forurensede luften bringes til å passere et filter som inneholder 50 m av et filtermateriale bestående av delvis forråtnet kompost som er oppnådd ved kompostering av avvannet slam fra et renseanlegg for kloakkvann, idet komposteringen er utført i nærvær av luft i en lukket reaktor med en hastighet på 1000 m 3 pr. time. Den luften som har passert gjennom filteret ble analysert med hensyn til de angitte forurensningene, hvorved det viste seg at innholdet av hver av disse var bragt ned til 0 ppm.. The polluted air is made to pass a filter containing 50 m of a filter material consisting of partially decomposed compost obtained by composting dewatered sludge from a sewage treatment plant, the composting being carried out in the presence of air in a closed reactor at a rate of 1000 m 3 per hour. The air that has passed through the filter was analyzed with regard to the specified pollutants, whereby it turned out that the content of each of these had been brought down to 0 ppm.
