VARIABLE FILTRATION SYSTEM FOR IMPROVING THE QUALITY OF AIR AND OTHER GASES AND LIQUIDS AND FOR IMPROVING ENERGY EFFICIENCY

摘要

The invention describes a variable filtration system based on the incorporation of movable filters and gates, such that a fluid to be filtered is forced to pass through a desired space; for example, through a filter with the selected efficiency or through a plurality of filters simultaneously, according to ad-hoc needs, or even through no filter, thereby saving energy and maintenance costs by deactivating the filters when they are not needed. A filter is selected or deactivated by means of movable filters that can be sliding, rotary or hinged, by selecting whether or not they interfere in the fluid current. The filter can also be selected by means of the incorporation of a hinged gate located in a bypass parallel to a pipe incorporating a fixed filter, such that opening or closing the gate determines whether or not the fluid passes through the filter.
