Den foreliggende opfindelse angår et pneumatisk affalds transportanlæg, der har et antal lukkelige åbninger til indføring af affald, og med en grovudskiller og en efterfølgende finudskiller til støv.The present invention relates to a pneumatic waste conveyor system having a plurality of closure openings for the introduction of waste and having a coarse separator and a subsequent dust separator.

5 I et for boligområder, sygehuse, industrier o.s.v.5 In one for residential areas, hospitals, industries, etc.

bestemt affaldstransportanlæg indføres skarn og affald gennem på hver enkelt etage anbragte åbninger, som kan lukkes, til lodrette rørskakter og samles oven for bundventilen, som udgør en sluseindretning til et system af 10 vandrette ledningsstammer, i hvilke det for transporten fornødne undertryk opretholdes ved hjælp af et fælles blæ-seaggregat. Det pneumatiske transportanlæg er forsynet med et spjældreguleret luftindtag ved en perifer del af hver ledningsstamme, og det fælles blæseraggregats suge-15 side er tilsluttet de vandrette ledningsstammer, idet der i kredsløbet er indsat serieforbundne separatorer til adskillelse af transportluft og skarn og affald, hvilke separatorer tjener som grovudskillere, henholdsvis finudskillere, som det bl.a. er beskrevet i svensk fremlæggel-20 sesskrift nr. 341.676.particular waste transport plant is introduced through the openings which can be closed on each floor, which can be closed to vertical pipe shafts and assembled above the bottom valve, which constitutes a locking device for a system of 10 horizontal conduits in which the negative pressure required for transport is maintained by means of a common blow saw. The pneumatic conveyor system is provided with a damper-regulated air intake at a peripheral portion of each wiring harness, and the suction side of the common blower assembly is connected to the horizontal wiring harnesses, with circuit-connected separators for separating conveying air and joints and debris, which separators are inserted. serves as coarse separators, or fine separators, such as is described in Swedish Patent Publication No. 341,676.

Grovudskilleren kan med fordel være placeret over en renovationsforbrændingsovn, eller den kan være beliggende over et komprimeringsorgan, hvorfra udskilt støv kan køres bort i en container. Når transportluften er endeligt renset 25 i finudskilleren, passerer den via en kontraventil og en lydfælde ud i det fri. Tid efter anden er det nødvendigt at lukke anlægget og rengøre finudskilleren. Ud over, at en sådan lukning af anlægget og rengøring af finudskilleren kræver tilsyn og spilder tid, er det også ofte et snavset 30 og uhygiejnisk, for ikke at sige sundhedsfarligt, arbejde.The coarse separator may advantageously be located above a refuse incinerator, or it may be located above a compression means from which separated dust can be disposed of in a container. When the transport air is finally purified 25 in the fin separator, it passes through a check valve and a sound trap into the open air. Time after time it is necessary to close the system and clean the separator. In addition to such a closure of the plant and cleaning of the separator requires supervision and wasting time, it is also often a dirty 30 and unhygienic, not to mention hazardous, work.

Dette gælder navnlig, hvis anlægget skal behandle inficeret materiale fra f.eks. sygehuse og slagterier eller ligefrem giftigt affald fra kemiske laboratorier. Der kan også i visse tilfælde være tale om radioaktivt affald.This is especially true if the plant is to treat infected material from e.g. hospitals and slaughterhouses or even toxic waste from chemical laboratories. There may also be radioactive waste in some cases.

35 Formålet for opfindelsen er at udforme anlæg get således, at driften kan blive kontinuerlig og hvor 2 143793The object of the invention is to design the plant so that the operation can be continuous and where

rengøringen af finudskilleren ikke spilder tid og medfører uhygiejnisk eller sunhedsfarligt manuelt arbejde .cleaning the separator does not waste time and results in unhygienic or harmful manual work.

Dette opnås ifølge den foreliggende opfindelse ved, 5 at finudskilleren er forsynet med en som vådudskiller indrettet beholderdel, i hvilken der sker en befugtning og sedimentering af det optagne støv, og at der er tilvejebragt organer til fjernelse fra beholderdelen og tilbageføring af det sedimenterede støv ved pneumatisk transport 10 til den forudgående grovudskiller gennem en i dennes øvre del udmundende overføringsledning.This is achieved according to the present invention in that the fine separator is provided with a container part arranged as a wet separator, in which wetting and sedimentation of the absorbed dust is effected and means are provided for removal from the container part and return of the sedimented dust by pneumatic conveying 10 to the preceding coarse separator through a transfer line opening in the upper part thereof.

Herved kan støvet i sedimenteret tilstand, d.v.s. som slam, føres tilbage til grovudskilleren og blandes med det øvrige affald, idet det på grund af dets fugtige til-15 stand ikke igen-rives med af transportluften til finudskilleren, men på kendt måde kan udtages blandet med det øvrige affald gennem en sluse i bunden af grovudskilleren.Hereby, the dust may be in a sedimented state, i.e. as sludge, is returned to the coarse separator and mixed with the other waste, because of its humid state, it is not recirculated by the transport air to the fine separator, but in a known manner can be withdrawn mixed with the other waste through a sluice. bottom of the coarse separator.

Fortrinsvis består organerne til fjernelse og til-20 bageføring af det sedimenterede støv af et med indløbs- og udløbslukker forsynet opsamlingskammer under finudskilleren, hvilket opsamlingskammer er forsynet med en separat, oplukkelig tilgang for atmosfærisk luft og gennem udløbslukket er tilsluttet overføringsledningen til grovudskil-25 leren.Preferably, the means for removing and returning the sedimented dust consist of a collection chamber provided with an inlet and outlet closure beneath the fin separator, which collection chamber is provided with a separate, openable access for atmospheric air and through the outlet closure the transfer line is connected to the coarse separator. .

Herved kan man på enkel og fordelagtig måde udnytte det kraftige undertryk i grovudskilleren til intermitterende tilbageføring af det i finudskilleren udskilte slam til grovudskilleren, uden at dette medfører nogen afbry-30 delse af driften af det pneumatiske affaldstransportanlæg.Hereby one can utilize in a simple and advantageous manner the strong negative pressure in the coarse separator to intermittently return the sludge separated in the fine separator to the coarse separator, without causing any interruption of the operation of the pneumatic waste transport system.

Opfindelsen vil i det følgende blive nærmere forklaret under henvisning til tegningen, som i snit viser et eksempel på en udførelsesform for et anlæg ifølge opfindelsen.The invention will be explained in more detail below with reference to the drawing, which shows in section an example of an embodiment of a plant according to the invention.
