Description
Støvfraskillingsaggregat av småsykloner. Dust separation unit of small cyclones.
Denne oppfinnelse vedrører en forbed-ret utførelse av et støvfraskillingsaggregat for rensning av støvblandede, gassformige medier. Det består av et antall ved siden av og over hverandre plaserte og mellom felles inn- og utløpskammere for mediet anordnede fraskillingsenheter i form av småsykloner, som hver består av en med et tangentielt rågassinnløp og et koaksialt i kapselen anbragt sentralrør som rengass-utløp samt nedentil gående over i en med støvutløp forsynt konisk avsmalnende del, idet støvutløpene for over hverandre værende fraskillingsenheter utmunner i et felles, i hovedsaken vertikalt støvavløpsrør. This invention relates to an improved design of a dust separation unit for cleaning dust-mixed, gaseous media. It consists of a number of separation units in the form of small cyclones placed next to and above each other and arranged between common inlet and outlet chambers for the medium, each of which consists of one with a tangential raw gas inlet and a central tube placed coaxially in the capsule as a clean gas outlet as well as below passing into a conically tapering part provided with a dust outlet, as the dust outlets for separation units located above each other open into a common, mainly vertical dust drain pipe.
Ved kjente utførelser av slike støvfra-skillingsaggregater har syklonenes oppmontering og deres tilslutning til nødvendige støvavløpsrør og den mellom inn- og ut-løpskammeret nødvendige skillevegg vist seg å være både kostbar og tidsspillende. Oppfinnelsen som tilsikter å eliminere disse mangler og å muliggjøre en enkel og hurtig oppmontering av aggregater av ønsket stør-relse, utmerker seg at hver fraskillingsen-het er utført med støvutløpet utmunnende i et med den koniske del sammenhengende rørstykke som danner en skrå vinkel med syklonkapslens lengdeakse og er utført med en byggelengde svarende til fraskillingsen-hetens innbyrdes deling i høyderetningen, hvorved disse rørstykker ved aggregatets oppmontering danner det nevnte vertikale støvavløpsrør. In known designs of such dust separation units, the mounting of the cyclones and their connection to the necessary dust drainage pipes and the partition wall required between the inlet and outlet chamber has proven to be both expensive and time-consuming. The invention, which aims to eliminate these shortcomings and to enable a simple and quick assembly of aggregates of the desired size, is distinguished by the fact that each separation unit is designed with the dust outlet opening into a piece of pipe connected to the conical part which forms an oblique angle with the cyclone capsule longitudinal axis and is made with a construction length corresponding to the separation unit's mutual division in the height direction, whereby these pipe pieces form the aforementioned vertical dust drain pipe when the unit is assembled.
Ved en hensiktsmessig utførelsesform for oppfinnelsen utføres hver enkelt syklon dessuten med en med den sylindriske kapsel sammenhengende ytre vegg som danner en rektangulær skive i vinkel med syklonens lengdeakse, hvilken skive er utført med en til syklonens innbyrdes deling svarende dimensjon og langs ytterkantene er utført med tilslutningsflenser eventuelt forsynt med hull for bolter, hvorved syklonene kan bygges innbyrdes sammen til en enhet av ønsket størrelse og derved også danne den ved slike fraskillingsaggregater nødvendige skillevegg mellom inn- og ut-løpskamrene. In a suitable embodiment of the invention, each individual cyclone is also made with an outer wall connected to the cylindrical capsule which forms a rectangular disk at an angle with the cyclone's longitudinal axis, which disk is made with a dimension corresponding to the cyclone's mutual division and is made with connection flanges along the outer edges possibly provided with holes for bolts, whereby the cyclones can be built together to form a unit of the desired size and thereby also form the necessary partition between the inlet and outlet chambers for such separation units.
Ofte sammensettes støvfraskillings-aggregater av vedkommende type av fraskillingsenheter som består av to sammenbyggede småsykloner, såkalte tvillingssykloner. Ifølge oppfinnelsen forsynes tvil-lingsyklonene da med et felles støvutløps-rør og en felles skive med tilslutningsflenser. Dust separation units of the relevant type are often composed of separation units consisting of two small cyclones assembled together, so-called twin cyclones. According to the invention, the twin cyclones are then provided with a common dust outlet pipe and a common disk with connection flanges.
Med en utførelse ifølge oppfinnelsen oppnåes ikke bare en forenklet oppmontering av fraskillingsaggregater av ønsket størrelse, men syklonenhetene utgjør dessuten alene alle nødvendige konstruksjons-elementer som kreves for i en røkgasskanal eller i et annet rom å montere et komplett støvfraskillingsaggregat. De med syklonene sammenhengende rørstykker danner nem-lig nødvendige støvavløpsrør og de på syklonkapslen anordnede vegger eller skiver danner tilsammen den nevntne skillevegg mellom inn- og utløpssidene. With an embodiment according to the invention, not only is a simplified mounting of separation units of the desired size achieved, but the cyclone units also alone constitute all the necessary construction elements required to mount a complete dust separation unit in a flue gas duct or in another room. The pipe pieces connected to the cyclones form the necessary dust drainage pipes and the walls or discs arranged on the cyclone capsule together form the aforementioned partition between the inlet and outlet sides.
Oppfinnelsen skal nu beskrives nær-mere i tilslutning til tegningen, som viser et eksempel på en utførelsesform av et støvfraskillingsaggregat utført. The invention will now be described in more detail in connection with the drawing, which shows an example of an embodiment of a dust separation unit.
På tegningen betegner 1 et antall ved siden av og over hverandre anordnede småsykloner i en skillevegg 10 mellom et inn-løpskammer 11 for rågass og utløpskammer 12 for rengass. Hver syklon består av en sylindrisk kapsel 3. 1 med et tangentialt rå-gassinnløp 2 og et koaksialt i kapselen anbragt sentralrør 6 som rengassutløp. Kapslen 3 går nedentil over i en med et støv-utløp 5 forsynt konisk avsmalnende del 4. In the drawing, 1 denotes a number of small cyclones arranged next to and above each other in a partition wall 10 between an inlet chamber 11 for raw gas and an outlet chamber 12 for clean gas. Each cyclone consists of a cylindrical capsule 3.1 with a tangential raw gas inlet 2 and a central tube 6 placed coaxially in the capsule as a clean gas outlet. The capsule 3 passes below into a conically tapering part 4 provided with a dust outlet 5.

I det viste tilfelle består fraskillings-aggregatet av et antall enkelte småsykloner, men oppfinnelsen kan — som tidligere In the case shown, the separation unit consists of a number of individual small cyclones, but the invention can - as before
nevnt — også avpasse ved støvfraskillings-aggregater oppbygget av enheter bestående mentioned — also adjust for dust separation aggregates made up of units consisting of
