The invention relates to a separating device for tubular flow-through devices () which serve for the extraction of liquids or gases from wells drilled in rock or deep wells, the separating device being suitable for the removal of sand and rock particles and comprising

Separating device for tubular flow-through devices

A separating device for removing sand and rock particles, and is an integral component of extraction equipment for extraction of liquids or gases from deep wells, having at least one ceramic filter module comprising: an annular stack of annular discs, the upper side of which has at least three elevations uniformly distributed over the circumference of the discs, the discs are stacked such that a separating gap for the removal of sand and rock particles is present between the individual discs, a coupling-on element at the upper end and a coupling-on element at the lower end of the annular stack, a clamping device bracing the annular stack, an outer cage, a coupling element at the upper end and a coupling element at the lower end of the filter module connecting the filter module to further components of the extraction equipment.

Wear-resistant separating device for removing sand and rock particles

The invention relates to a component comprising a plurality of plates stacked on each other, at least one of said plates being made of a ceramic material and in which a channel area is formed of fluid flow guide channels by means of webs, said channels having a flow connection to inlet and outlet openings, wherein the stack of plates is connected by force fit by means of a clamping device, and wherein a flat seal is disposed between each of the individual plates of the stack, wherein the flat seal is made of an elastic and/or compressible material and covers both the channel area and the areas encompassing the inlet and outlet openings, and at least partially covers the top sides of the webs forming the channels. The components according to the invention are pressure-tight, resistant to thermal shock, and can be dismantled.
