Description

Verfahren zur Erzielung einer gleichmäßigen Filterwirkun g bei Gasfiltern mit körnigem oder faserigem Filtermaterial.Process for achieving a uniform filter effect in gas filters with granular or fibrous filter material.

Bei den Gasfiltern bekannter Bauart, in welchen sich körniges oder faseriges Filtermaterial in dünner Schicht in vertikaler Richtung von oben nach unten bewegt und der zu entstäubende Gasstrom rechtwinklig zu dieser Bewegungsrichtung hindurch gesaugt oder gedrückt wird, nimmt die Staubablagerung im Filtermaterial von oben nach unten zu, die Gasdurchlässigkeit des Materials dagegen ab. In the gas filters of known design, in which granular or fibrous filter material in a thin layer in the vertical direction from top to bottom moved below and the gas flow to be dedusted at right angles to this direction of movement is sucked or pushed through, the dust build-up in the filter material decreases from top to bottom, the gas permeability of the material decreases.

Hieraus folgt, daß der zu filtrierende Gasstrom vorwiegend die oben durchlässige Filterschicht zu passieren bestrebt ist, wobei aber der gewünschte Reinheitsgrad des Gases, infolge der größeren Porosität der oberen Schicht, nicht erreicht wird.It follows that the gas stream to be filtered is predominantly the one above A permeable filter layer strives to pass, but the desired one The degree of purity of the gas, due to the greater porosity of the upper layer, is not is achieved.

Der Zweck der vorliegenden Erfindung ist es nun, den Filterwiderstand und die Filterwirkung auf der ganzen Fläche gleichmäßig zu gestalten, was dadurch erreicht wird, daß die Stärke der Filtermaterialschicht in der Gasdurchgangsrichtung, der aufgenommenen Staubmenge und Durchlässigkeit des Materials entsprechend, oben stärker als unten bemessen wird. Dies wird z. B. dadurch erreicht, daß man das Filtermaterial zwischen einander gegenüberliegenden Jalousiewänden sich bewegen läßt, deren Abstand voneinander von oben nach unten zu regelbar abnimmt. The purpose of the present invention is now to control the filter resistance and to make the filter effect evenly over the entire surface, which means it is achieved that the thickness of the filter material layer in the gas passage direction, according to the amount of dust absorbed and the permeability of the material, above stronger than is dimensioned below. This is z. B. achieved by the fact that the filter material can move between opposing blind walls, the distance between them from each other from top to bottom to be controllable decreases.
