Abstract
To clean industrial exhaust gas, esp. for the removal of sulphur from the emissions from glass works, a mixt. is used of lime and soda.
Description
Es sind verschiedene Mittel zur Rauchgasreinigung bekannt; so ist insbesondere auch die Verwendung von Kalk zur Rauchgas entschwefelung von Kohlekraftwerken und Müllverbrennungs anlagen bekannt. Hierbei wird das entstehende Abfallprodukt in Form von Gips beispielsweise dadurch entsorgt, daß Gips kartonplatten hergestellt werden. Es ist allerdings absehbar, daß die bei der Rauchgasreinigung anfallenden Mengen an Gips irgendwann vom Markt nicht mehr aufgenommen werden können. Es ist daher von immenser Wichtigkeit, für die bei der Rauchgasreinigung bzw. Rauchgasentschwefelung entstehenden Abfallprodukte Entsorgungsmöglichkeiten zu schaffen.Various flue gas cleaning means are known; so is especially the use of lime for flue gas Desulphurization of coal-fired power plants and waste incineration plants known. This creates the waste product disposed of in the form of gypsum, for example, in that gypsum cardboard sheets are made. However, it is foreseeable that the amount of gypsum obtained during flue gas cleaning cannot be accepted by the market at some point. It is therefore of immense importance, for which at the Flue gas cleaning or flue gas desulphurization occur Waste products to create disposal options.
So wurde nun herausgefunden, daß durch eine Mischung aus Kalk und Soda zur Rauchgasentschwefelung der Abgase einer Glashütte das hierbei entstehende Abfallprodukt dem Produktionskreislauf wieder zugeführt werden kann. Es entsteht mithin durch die Rauchgasreinigung kein Abfall, der entsorgt werden müßte.So it has now been found that a mixture of lime and soda for flue gas desulfurization of the exhaust gases Glashütte the resulting waste product Production cycle can be fed again. It there is therefore no waste from flue gas cleaning should be disposed of.
Es hat sich insbesondere als vorteilhaft die Verwendung einer Mischung aus Hydratkalk und "Soda leicht" herausgestellt. Unter "Soda leicht" wird ein NA2 CO3 Gemisch mit einem Anteil von 0,3% NA CL bezeichnet; "Soda schwer" hingegen hat einen Anteil an NA CL in Höhe von 0,15%. Das Mischungsverhältnis zwischen Kalk und Soda beträgt etwa zwischen 50% Soda und 50% Kalk und 70% Soda und 30% Kalk.It has proven particularly advantageous to use a Mixture of hydrated lime and "soda light" highlighted. Under "Soda light" is a NA2 CO3 mixture with a share denoted by 0.3% NA CL; "Soda heavy", however, has one NA CL share of 0.15%. The mixing ratio between lime and soda is between 50% soda and 50% Lime and 70% soda and 30% lime.
Gegenstand der Erfindung ist ebenfalls die Verwendung von Hydratkalk und Soda, insbesondere von "Soda leicht" zur Entschwefelung der Rauchgase einer Glashütte.The invention also relates to the use of Hydrated lime and soda, especially from "soda light" for Desulphurization of the flue gases from a glassworks.
