Abstract
A filter apparatus is provided for the filtering of substances from a fluid having a filter housing (2) which bounds a filter space (6) and which has an inlet (3) and an outlet (4) for the fluid to be filtered and having a filter element (5) which is provided in the filter space (6) and which is designed and arranged so that the filtering fluid can only flow through the filter element (5) from the inlet (3) to the outlet (4) of the filter housing (2) in operation, wherein a heating device (10) is provided for the heating of the fluid which includes a microwave source (11) in order to act on the fluid by microwaves.
Claims13
A filter apparatus for the filtering of substances from a fluid comprising a filter housing that is transparent to microwaves, is made of a ceramic material or of a polymer material, that bounds a filter space and has an inlet and an outlet for the fluid to be filtered, a casing surrounding the filter housing, a filter element which is provided in the filter space and which is designed and arranged such that the filtering fluid can only flow through the filter element from the inlet to the outlet of the filter housing in operation, and a heating device for heating the fluid which includes a microwave source in order to act on the fluid by microwaves, the casing including a waveguide for directing microwaves from the microwave source for heating the fluid within the filter housing, wherein said filter space is separated from said casing and said microwave source by said housing.
A filter apparatus for filtering substances from a fluid comprising a filter for the fluid, a housing for the filter including an inlet and an outlet for flowing the fluid from the inlet past the filter to the outlet, a microwave energy source for subjecting the fluid to microwaves, said housing being formed by a fluid-impervious wall interposed between the microwave source and the filter and constructed of a material that has at most a low absorption capacity for the microwave, a casing surrounding the housing, wherein said filter is separated from said casing and said microwave energy source by said housing, and a waveguide associated with the casing for directing the microwave from the microwave source to the fluid flowing between the inlet and the outlet.
