ABSTRACT:
Filtration apparatus in which the filter medium is in the form of a mat assembled with a support grid which is caused to traverse through a filter chamber in a zig zag path. The mat and support grid extend between the side walls of the filter chamber and are advanced by turning rolls disposed at upper and lower levels. The support grid for the filter mat extends between sealing flanges projecting from the side walls of the filter chamber and auxiliary support for the support grid may be provided by employing a foraminous shelf extending between the flanges. The filter medium is disposed so that its edges overlie the sealing flanges, thereby preventing flow of gaseous medium around the edges of the filter mat. Sealing engagement between the sealing flanges and the filter mat is assured by the inclusion of a series of apertures spaced along the length of the flanges. The undersurface of the filter mat faces the downstream side of the filter housing so that the reduced pressure downstream of the filter mat is applied to the undersurface of the filter mat and effects firm engagement with the flanges.
