Description
Filtermasse gegen Quecksilberdämpfe Die erfindung bezieht sich auf Schutzfilter gegen Quecksilberdämpfe in der chemischen, pharmazeutischen, elektrotechnischen, textilen Industrie u. a.Filter mass against mercury vapors The invention relates to Protection filter against mercury vapors in chemical, pharmaceutical, electrotechnical, textile industry and others
In derartigen Schutzeinrichtungen (Filtern) wird bekanntlich als wirksame Füllung in verschiedener Weise imprägnierte und präparierte aktive Kohle benutzt, bei der die Imprägnierung mit Jod, Chlor u. dgl. erfolgt. Die Widerstands dauer solcher Filter ist ziemlich kurz. Die Zubereitung der Imprägnierlösungen bereitet Schwierigkeiten. Die Atmosphäre der Betriebsräume wird mit Joddämpfen verunreinigt. Die Jod- und Chlorimprägnierfüllung ist stark korrodierend für die Blechbüchsen der Filter und ihre anderen Bestandteile. Es ist die Einlagerung solcher Filter somit sehr problematisch. Die Oberflächenbearbeitung solcher Blechbüchsen ist zu kostspielig. In such protective devices (filters) is known as effective filling in various ways impregnated and prepared active charcoal used, in which the impregnation with iodine, chlorine and the like takes place. The resistance The duration of such filters is quite short. The preparation of the impregnation solutions prepares Trouble. The atmosphere of the operating rooms is contaminated with iodine vapors. The iodine and chlorine impregnation filling is highly corrosive for the tin cans the filter and its other components. It is the storage of such filters therefore very problematic. The surface treatment of such tin cans is too expensive.
Gemäß der Erfindung werden zur Imprägnierung der aktiven Kohle Stoffe verwendet, durch welche diese Nachteile vermieden werden und welche die Widerstandsdauer der Filter bedeutend verlängern. According to the invention, substances are used to impregnate the active charcoal used, by which these disadvantages are avoided and which the resistance duration significantly lengthen the filter.
Die Zubereitung der gesundheitsunschädlichen und die übrigen Filterbestandteile nicht korrodierenden Stoffe wird vereinfacht.The preparation of the non-harmful and the other filter components non-corrosive substances is simplified.
Die Erfindung betrifft eine Filtermasse gegen Quecksilberdämpfe mit aktiver Kohle als Träger der die Quecksilberdämpfe chemisch bindenden Reagenzien, bei der als Imprägnierstoff Alkalipolysulfide, Alkalisulfide oder Alkalihydrosulfide verwendet werden. The invention relates to a filter material against mercury vapors Active carbon as a carrier of the reagents that chemically bind the mercury vapors, in the case of the impregnating agent alkali polysulphides, alkali sulphides or alkali hydrosulphides be used.
Bei der Zubereitung der aktiven Kohle wird unter Ausnutzung der Imprägnierlösungen in der üblichen Weise gemäß den nachstehenden Beispielen vorgegangen. Die imprägnierte Aktivkohle wird dann ebenfalls in der iiblichen Weise in die Blechfilter gefüllt. When preparing the active charcoal, the impregnation solutions are used proceeded in the usual manner according to the examples below. The impregnated Activated charcoal is then also filled into the sheet metal filter in the usual way.
Geht die Ouecksilberdämpfe enthaltende Luft durch das Filter oder eine Schutzeinrichtung gegen Quecksilberdämpfe hindurch, wird das Quecksilber aus der Luft restlos durch den Imprägnierstoff des Filters gebunden. Die Luft gelangt gänzlich frei von Quecksilberdämpfen aus dem Filter. Zum Auffangen von Ouecksilberdämpfen werden nach der Erfindung Alkalipolysulfide, Alkalisulfide und Alkalihydrosulfide verwendet, z. B. Natriumdisulfid, Natriumsulfid, Natriumhydrosulfid u. a.Does the air containing mercury vapors pass through the filter or A protective device against mercury vapors will pass through the mercury the air is completely bound by the impregnating agent of the filter. The air gets in Completely free of mercury vapors from the filter. For collecting mercury vapors According to the invention, alkali polysulphides, alkali sulphides and alkali hydrosulphides used, e.g. B. sodium disulfide, sodium sulfide, sodium hydrosulfide and others.
Als sehr brauchbar haben sich z. B. folgende Imprägnierungen bewährt: a) Es werden 100g aktive Kohle durch Bespritzen mit einer Lösung von 4 g Natriumpolysulfid in 30 cm3 Wasser imprägniert, worauf die aktive Kohle wieder ausgetrocknet wird. b) Es werden 100 g aktive Kohle in eine Lösung von 5 g Natriumpolysulfid in 200 cm3 Wasser getaucht, und nach 30 Minuten wird das Wasser abgegossen und die Kohle ausgetrocknet. c) Es werden 100 g aktive Kohle mit einer Lösung von 10 g Natriumsulfid in 100 cm3 Wasser imprägniert und dann ausgetrocknet. d) Es werden 100 g aktive Kohle mit einer Lösung von 15 g Natriumhyrosulfid in 100 cm3 Wasser imprägniert und dann ausgetrocknet. As very useful z. B. the following impregnations have been tried and tested: a) There are 100 g of active charcoal by spraying with a solution of 4 g of sodium polysulfide impregnated in 30 cm3 of water, whereupon the active charcoal is dried out again. b) There are 100 g of active charcoal in a solution of 5 g of sodium polysulphide in 200 cm3 of water, and after 30 minutes the water is poured off and the coal dried out. c) There are 100 g of active charcoal with a solution of 10 g of sodium sulfide impregnated in 100 cm3 of water and then dried out. d) 100 g become active Charcoal impregnated with a solution of 15 g of sodium hyrosulphide in 100 cm3 of water and then dried out.
Durch die Erfindung wird ein wesentlicher Fortschritt gegenüber dem Stand der Technik erzielt. Die Arbeiter werden in den von Quecksilberdämpfen bedrohten Betriebsräumen selbst bei hohen Konzentrationen von Quecksilber in der Luft sehr viel besser geschützt. Durch die bisher üblichen Jodfilter konnte ein solcher Schutz nicht gewährleistet werden. Die Dauer der Wirksamkeit der Filtermasse gemäß der Erfindung ist bis zu 700/0 höher als die der bisherigen Filter. Sie ist natürlich abhängig von der Intensität des Durchflusses der Luft und vom Quecksilbergehalt pro Liter Luft. Die Blechbüchsen des Filters benötigen keine kostspielige Oberflächenbearbeitung, da der Imprägnierstoff nicht für die Filterbestandteile korrodierend ist. The invention is a significant advance over the State of the art achieved. The workers are threatened by mercury vapors Operating rooms even with high concentrations of mercury in the air much better protected. Such protection could be achieved through the iodine filters used up to now cannot be guaranteed. The duration of the effectiveness of the filter mass according to the Invention is up to 700/0 higher than that of previous filters. It is natural depending on the intensity of the air flow and the mercury content per liter of air. The tin cans of the filter do not require any costly surface treatment, as the impregnating agent is not corrosive to the filter components.
