SLOTTED PLATE FILTER (VERSIONS) Russian patent published in 2014 - IPC B01D29/44 B01D46/40 

FIELD: chemistry.

SUBSTANCE: filter contains a case with input and output branch pipes, a filtering element, assembled from plates. An assembly composition includes plates, on both surfaces of which made are oriented parallel projections, located opposite the projections of the other plate. In accordance with the first version of implementation the plates in the assembly are made rectangular and are located parallel to each other. The assembly composition also includes the plates with smooth planes, alternating with the plates with projections. The projections on the plates are made equal in size, are placed at an acute angle to their central longitudinal axes and are located in a mirror-like way on both planes of the plates. In accordance with the second version of implementation the plates in the assembly are made rectangular and are located at an angle to each other with formation of a volume with a curved slot surface, connected with the input branch pipe. The composition of the assembly also includes the plates with smooth planes, alternating with the plates with projections. The projections on the plates are made equal in size, are located at an acute angle to their central longitudinal axes and are located in a mirror-like way on both planes of the plates. The plates with smooth surfaces form with lateral surfaces of the projections slotted filtering inputs for the passage of a medium to be filtered from the volume with the curved slot surface, which can be made open or closed.

EFFECT: high degree of reliability.
