De uitvinding heeft betrekking op het afscheiden en filteren van droge of semi-droge, vaste stofpartikelen, vocht of gassen uit een afgas- of luchtstroom. Doel van het onderhavige filterelement gekenmerkt door het filtraat bestaande uit hydrokorrels of permeabele gesinterde kleikorrels al dan niet gemixt een extra adsorbent is het bereiken van een zo hoog mogelijk filteroppervlak en een zo laag mogelijke drukval over het filterelement, het laten neerslaan van condensaten en of luchtvochtigheid op het filtraat, het adsorberen van toxische gassen, het te kunnen bloodstellen aan hoge temperaturen en het op economisch verantwoorde wijze te kunnen produceren. 1043558EXTRACT Rectangular or square or cylindrical filter element, with a housing made of metal or plastic, characterized by the filtrate consisting of hydro granules or permeable sintered clay granules whether or not mixed with activated carbon or urea or other active adsorbent, which is held together by the housing and a fine-mesh metal or plastic mesh through which an off-gas to be filtered can be passed and can therefore be used as a dust filter and or as a gas filter element and or as a catalyst filter. The invention relates to the separation and filtering of dry or semi-dry solid particles, moisture or gases from an off-gas or air stream. The purpose of the present filter element, characterized by the filtrate consisting of hydro granules or permeable sintered clay granules, whether or not mixed with an additional adsorbent, is to achieve the highest possible filter surface and the lowest possible pressure drop over the filter element, to allow condensates and/or air humidity to precipitate. on the filtrate, to adsorb toxic gases, to be able to expose it to high temperatures and to be able to produce it in an economically responsible manner. 1043558

De oitvinding heeft batrekking op het afscheiden an filteren van droge of semi~droge, vaste stofpartikelen, voeht of gassen uit een afgas~ of luchtstroom, De hierboven aangegeven afscheiding en filtratis wordt 16 bewerkstelligd door het filtraat bestaande uit pernaabele hydrokorrels en of minsrale korrels en of gesinterde kogelvormige kleikorrels gevortd als zferischs bollen die als sen bed op- en tegenslkaar aan gestapeld liggen en op hun plaats gehouden worden door de wanden van het filterelement en esn open metalen of kunststol gaas van het filterelemant waardoor de lucht gemakkelijk kan doorstromen.The invention relates to the separation and filtration of dry or semi-dry solid particles, moisture or gases from a waste gas or air stream. or sintered spherical clay grains vortexed as spherical spheres stacked up and against each other as a bed and held in place by the walls of the filter element and an open metal or synthetic mesh of the filter element through which air can flow easily.

Doel één van de uitvinding is te voorzien in sen filterelement die de (al dan niet door een ventilator afgezogen} lucht door het hier besproken filterslement voert 2G waarmee de aflocht kan worden gefilterd van Ïijnstof partikelen en of Ítoxischs}gassen, Ben tweede doel is het bereiken van een zo laag mogelijke drukval van des luchtstroming over het onderhavide filterelement.The object of one of the inventions is to provide a filter element which carries the air (whether or not extracted by a fan) through the filter element 2G discussed here, with which the discharge can be filtered of oxygen particles and/or toxic gases. The second aim is to achieving the lowest possible pressure drop of the air flow over the present filter element.

Een derde doel van het onderhavige filter is het laren neerslaan van condensaten en of luchtvochtigheid op hat Ziltraat van het underhavige filterelement bestaande uit minsrale hydroksrrels.A third object of the present filter is to precipitate condensates and/or air humidity on the salt of the present filter element consisting of mineral hydrosrrels.

Fan vierde doal van het onderhavige filter is door hat 3% onderhavige filtraat eventueel te mengen Net aktieva koolstof om toxische gassen te kunnen adscrberen.The fourth purpose of the present filter is to optionally mix the 3% present filtrate with activated carbon in order to be able to adsorb toxic gases.

Een vijfde doel van het onderhavige filtraah en filterelement dat behoudens het Tiltraar gygsheel uit metalen onderdelen kan bestaan, is, het te kunnen bloodstellen aan hoge Lemperaturern, Een zesde doel van Det hier besproken filter is te konnen tot esn economisch verantwoorde productie van het ónderhavige filterelement ten opzichte van bestaande filtervslementen, De uitvoering. de diepte en de gelaagdheid van het 49 onderhavige filter, alsmede de stapeling van het onderhavigs filtraat als beschreven in fig. 1. punt 1,4 is afhankelijk van de vorm van de filterbehuizing als beschreven in fig 1. punt 2., de buitenwanden, de wanddiepte, de wandbreedte en de wandhoogte van het onderhavige filterslement, alsmede door het gebruikte gaas dat het filtrast bijelkaar hondt als beschreven in fig. 1. punt 3.A fifth aim of the present filtraah and filter element, which, apart from the Tiltraar gygsheel, can consist of metal parts, is to be able to expose it to high Lemperaturern. A sixth aim of the filter discussed here is to enable an economically responsible production of the present filter element. compared to existing filter elements, The implementation. the depth and stratification of the present filter, as well as the stacking of the present filtrate as described in fig. 1. item 1.4 depends on the shape of the filter housing as described in fig. 1. item 2., the outer walls, the wall depth, the wall width and the wall height of the present filter element, as well as due to the gauze used that holds the filter bag together as described in fig. 1. point 3.
