Description
Przedmiotem wynalazku jest sposób otrzymywania siatek filtrujaco-sorpcyjnych o róznych rozmiarach oczek i srednicach nitek, z ewentualna impregnacja katalityczna.The subject of the invention is a method of obtaining filtering-sorption meshes of various sizes mesh and thread diameters, with possible catalytic impregnation.
Dotychczas znane sa siatki filtrujace wykonywane z róznego rodzaju metali oraz z tkanin pochodzenia roslinnego,zwierzecego lub sporzadzonych z wlókien syntetycznych. Siatki te sluza do rozsiewania lub oddzielania poszczególnych frakcji materialów sypkich oraz do filtracji zawiesin. Znane sa równiez masy sorpcyjne wykonywane zwegli aktywnych. Masy te sluza do sorpcji materialów gazowych, par, cieczy i cial stalych z medium gazowego lub plynnego.So far, filtering meshes made of various metals and fabrics of origin are known vegetable, animal or made of synthetic fibers. These nets are used for spreading or separation of individual fractions of loose materials and for filtration of suspensions. The masses are also known sorption made of active carbon. These masses are used for the sorption of gaseous materials, vapors, liquids and bodies solids with a gaseous or liquid medium.
Natomiast dla oczyszczania powietrza lub innych substancji gazowych i cieklych z filtrowanego medium w postaci par, gazów i cial stalych w stanie zawieszonym, zachodzi koniecznosc ukladania warstw z materialów filtrujacych i sorpcyjnych.. Takie warstwy filtrujaco-sorpcyjne charakteryzuja sie wysokimi oporami aerodynamicznymi, a ponadto ich wykonanie jest bardzo pracochlonne i skomplikowane.However, for cleaning air or other gaseous and liquid substances from the filtered medium in the form of vapors, gases and solids in a suspended state, it is necessary to lay layers of materials filtration and sorption layers. Such filtering-sorption layers are characterized by high resistance aerodynamic and, moreover, their execution is very laborious and complicated.
Celem wynalazku jest usuniecie powyzszych wad i niedogodnosci przez opracowanie sposobu otrzymywania takich siatek, któreby umozliwily jednoczesne przeprowadzanie sorpcji i filtracji bez zastosowania dodatkowych materialów filtracyjnych. Cel ten zostal osiagniety za pomoca sposobu otrzymywania siatek filtrujaco-sorpcyjnych wedlug wynalazku. Istota wynalazku polega na tym, ze tkaniny pochodzenia roslinnego, zwierzecego lub sporzadzone z wlókien syntetycznych, najpierw nasyca sie kwasem fosforowym lub innymi substancjami odciagajacymi wode jak chlorek cynku, rodanek amonu, siarczki alkaliczne oraz siarka. Nastepnie tkaniny suszy sie w celu usuniecia wody i aktywuje droge ogrzewania w temperaturze 450 do 850°C, korzystnie bez dostepu powietrza. Czas aktywacji reguluje sie tak, aby otrzymane siatki uzyskaly wymagane wlasciwosci mechaniczne i sorpcyjne. W przypadku koniecznosci uzycia powyzszych siatek jako katalizatora, impregnuje sie je roztworami odpowiednich soli. Roztwory te w procesie aktywacji droga ogrzewania powyzej temperatury ich rozkladu przechodza w substancje katalityczne czynne, osadzone w lub na siatkach w postaci tlenków lub innych produktów rozkladu o katalizujacych wlasnosciach.The object of the invention is to remedy the above drawbacks and inconveniences by developing a method obtaining such meshes that would enable simultaneous sorption and filtration without application additional filter materials. This aim has been achieved by the method of obtaining meshes filtering and sorption agents according to the invention. The essence of the invention consists in the fact that fabric of plant origin, animal or made of synthetic fibers, first saturated with phosphoric acid or other water-extracting substances such as zinc chloride, ammonium thirium, alkali sulfides and sulfur. Next the fabrics are dried to remove water and a heating pathway is activated at 450 to 850 ° C, preferably without air access. The activation time is adjusted so that the obtained meshes obtain the required properties mechanical and sorption. If it is necessary to use the above meshes as a catalyst, they are impregnated them with solutions of appropriate salts. These solutions in the process of activating the path of heating above their temperature decomposition turns into active catalytic substances, embedded in or on grids in the form of oxides or other decomposition products with catalytic properties.
Tak otrzymane siatki ulozone w pakietach jedno lub wielowarstwowych latwo przepuszczaja strumien gazów, par lub cieczy lecz zatrzymuja niektóre ich skladniki droga mechaniczna przez filtracje i fizykochemiczna2 93 430 przez sorpcje, badz tez zmieniaja je odpowiednio katalitycznie, bez stwarzania wysokich oporów aerodynamicznych.The meshes obtained in this way, arranged in single or multi-layer packages, easily pass the stream gases, vapors or liquids, but retain some of their components by mechanical means through filtration and physicochemical2 93 430 by sorption, or change them appropriately catalytically, without creating high resistance aerodynamic.
Ponizej przedstawiono przyklad otrzymywania siatki filtrujaco-sorpcyjnej..An example of preparing a filtering-sorption mesh is presented below.
Przyklad I. Jeden kilogram tkaniny bawelnianej pojedynczo lub zlozonej z kilku warstw w ksztalcie krazka, zanurza sie w kapieli 20% kwasu fosforowego do calkowitego i równomiernego nasycenia. Po odciagnieciu nadmiaru kwasu fosforowego, krazki tkaniny suszy sie przez okolo 2 godziny w temperaturze 120°C do calkowitego wysuszenia. Wysuszona tkanine umieszcza sie w piecu muflowym, podgrzewa z szybkoscia 5 do 10°C na minute do temperatury 850°C i pozostawia w tej temperaturze na okres 6 godzin.Example I. One kilogram of cotton fabric individually or in several shaped plies the disc is immersed in a 20% phosphoric acid bath until it is completely and evenly saturated. After by drawing off excess phosphoric acid, the cloth discs are dried for approximately 2 hours at temperature 120 ° C until completely dry. The dried fabric is placed in a muffle furnace and heated at a rate of 5 to 10 ° C per minute up to a temperature of 850 ° C and left at this temperature for 6 hours.
W czasie takiego procesu karbonizacji powstaje uklad zblizony wygladem do siatki.During this process of carbonization, an arrangement similar in appearance to the mesh is created.
Przyklad II. W celu nadania siatce filtrujaco-sorpcyjnej odpowiednich wlasnosci katalitycznych postepuje sie w sposób nastepujacy. Otrzymana sposobem przedstawionym w przykladzie I siatke, nasyca sie amoniakalnym roztworem amino-miedziowo-srebrowo-chromowym, a nastepnie suszy w temperaturze 120°Cdo calkowitego wysuszenia i aktywuje przez podniesienia temperatury do 180°C w piecu muflowym przy bardzo slabym doplywie powietrza. Aktywacje prowadzi sie w taki sposób, aby nie nastapilo spalenie substancji weglowej.Example II. In order to provide the filtering-sorption mesh with appropriate catalytic properties the procedure is as follows. The mesh obtained by the method shown in Example 1 becomes saturated with ammoniacal amino-copper-silver-chromium solution, then dried at a temperature of 120 ° C to completely dry and activated by raising the temperature to 180 ° C in a muffle furnace at very poor air supply. Activations are carried out in such a way that the substance does not burn up coal.
