Abstract: A configuration of two cyclones for separation of solids from a solids-gas mixture wherein the gas outlet of a first cyclone is fluidly connected to an outlet conduit provided with a gas outlet opening and the gas inlet of the second cyclone is connected to an inlet conduit provided with a gas inlet opening wherein the outlet and inlet conduit are arranged co-axial such that gas leaving the outlet opening of the outlet conduit enters the inlet opening of the inlet conduit and gas from the exterior of the cyclone configuration can enter the gas inlet opening of the inlet conduit, wherein the outlet conduit and the inlet conduit are kept in a co-axial position relative to each other by means of guiding means which are attached to outlet conduit or to inlet conduit and extend to the opposite conduit thereby allowing movement of the inlet and outlet conduits relative to each other in the axial direction only.

Abstract: Swirl tube separator for separating solids from a gas-solid containing feed comprising a tubular housing, an inlet for introducing a gas-solids mixture at one end of said housing, a solids outlet opening at the opposite end of said housing, and a co-axial positioned tubular gas outlet conduit placed at an end of said housing, wherein along the axis of the tubular housing a vortex extender pin is present.

Abstract: A filter assembly having a plurality, preferably at least substantially vertically mounted, longitudinal elongated filter elements that are suitable for separating fluid from solid particles, having an open upper end sealed into a sealing device and a closed bottom end attached to a filter support that is mounted on a filter grid, in which the filter grid has a plurality of grid elements together forming a grid, wherein at least a portion of the cross-section of the grid elements between two adjacent filter elements is pointiform. The invention further pertains to a filter grid and a filter vessel containing at least one filter assembly.
