Abstract

The invention relates to a chemisorption filter having a frame construction (1) and a filter cloth (2) supported thereon. In order to avoid detachment in regions of the filter cake from the filter cloth, support strips or support rings (3) are arranged in the region of the filter surfaces formed by the filter cloth (2), on which support strips or support rings the filter cake can additionally support itself. <IMAGE>

Description

Beschreibung und Erläuterung zur Zusatz-PatentanmeldungDescription and explanation of the additional patent application

Cheinisorptionsfilter mit Additiv-Arretierungen Zusatz zu P 30 20 049.8 Es hat sich gezeigt, daß Filtertaschen in größerer Ausbildung die Kalkhydratschicht nicht egalisiert aufbauen lassen, sondern bei Schichtstärken von mehr als z.B. 4 mm regelrechte Fladen ausbrechen, die eine homogene Chemisorption auf den Filterflächen somit dann verhindern.Cheinisorption filter with additive locks Addition to P 30 20 049.8 It has been shown that larger size filter pockets contain the hydrated lime layer Do not let it build up evenly, but with layer thicknesses of more than e.g. 4 mm of regular flatbreads break out, which have a homogeneous chemisorption on the filter surfaces thus then prevent.

Aufgrund dieser Erfahrung wird erfindungsgemäß vorgeschlagen, die Filterflächen in gewissen Abständen mit Staubleisten zu versehen, vorzugsweise in flexibler Ausführung. Die erfindungsgemäße Ausführung ist in der beiliegenden Zeichnung dargestellt: mit (1) die Lochblechanordnung z.B. einer Filtertasche oder eines Filterschlauchstützrahmens mit (2) das Filtertuch mit (3) die Stützleisten oder Stützringe, auf die sich praktisch das Chemisorptionsmittel in gewissen Abständen auf der Filtertuchfläche abstiitzen kann, und gleichzeitig ein Halt auf den Stützleisten gewahrleistet wird.Based on this experience, it is proposed according to the invention that To provide filter surfaces with dust strips at certain intervals, preferably in flexible execution. The embodiment according to the invention is shown in the accompanying drawing shown: with (1) the perforated plate arrangement, e.g. a filter pocket or a filter hose support frame with (2) the filter cloth with (3) the support strips or support rings, on which the chemisorbent practically rests at certain intervals can support on the filter cloth surface, and at the same time a hold on the support strips is guaranteed.

Vorzugsweise sind diese Stützleisten elastisch ausgebildet, so daß sie bei Druckschock gewissermaßen nachgeben und somit ein Reinigen der Filter nicht hindern.These support strips are preferably designed to be elastic, so that they give way to a certain extent in the event of a pressure shock and therefore no cleaning of the filter prevent.
