<p>A filter plant comprising a number of filter chambers possesses a fluidics valve on the inlet side, leading to a pair of ducts which each discharge into a separate filter chamber; when a switch over device is actuated, the incoming flow is diverted from one of these ducts to the other, so that the filter material in the chamber associated with the first duct is bent to clean it. Each filter chamber pref. contains a number of suspended tubular filters, and, in addition to bottom inlet and top discharge ducts, has a bottom hopper discharge for dirt. The use of the fluidic principle to change the medium flow simplifies the layout and minimises the number of moving parts.</p> |
