The device (100) serves to separate solid particles from the water of a flow (E) feeding a hydraulic machine of the turbine, pump, or turbine-pump type. The device has flow inlet and outlet zones (104, 105) for the flow that are spaced apart along an advance axis (X100) of flow advance-through the device (100). The device (100) comprises a plurality of ducts (110) placed in parallel, each having a mouth and a downstream end between the inlet zone (104) and the outlet zone (105). In section perpendicular to the advance axis (X100), each duct presents a section in the form of a spiral with a radius of curvature that increases from the mouth towards the downstream end or from the downstream end towards the mouth, with each duct (110) presenting a thickness measured in a generally radial direction relative to the advance axis that is less than 10% of the width (l110) of said duct, measured parallel to said axis (X100).

摘要:
A vertically oriented separator for separating liquid from a gas stream, where the incoming fluid enters the separator through an inlet nozzle arranged mainly perpendicular to the center axis of the separator and communicates with a circular swirl-inducing inlet device which is outwardly limited by the separator wall, inwardly limited by a mainly centrally arranged pipe and upwardly limited by a sealed top cover. The separator includes a first separation compartment arranged below the pipe and a second separator compartment arranged above the pipe, so the incoming fluid successively and under continuous swirl is forced to pass from the circular swirl-inducing inlet device to the first separator compartment and further through the pipe to the second separator compartment.
摘要:
Apparatus is described for separating particulate material from an airstream established by suction. The apparatus comprises a primary separation chamber (12) in which particles are separated from the airstream therein by centrifugal force, a main particle collecting region (14) into which the particles separated by the primary separation can fall under gravity, and a secondary separation chamber (90) downstream of the primary chamber (12), to which air and particles not separated in the first chamber, pass. An air outlet in the secondary chamber allows air substantially free of particles to exit. An intermediate particle collecting region (22) is associated with the secondary chamber, in which particles collect after separation by centrifugal force from the air flowing through the secondary chamber (90). A valve (41) is provided between the intermediate particle collecting (22) region and a second particle collecting region (14), which is closed while air flows through the apparatus but which is opened when airflow ceases, to allow particles in the intermediate region (22) to pass into the second region (14).

The present invention is directed to a system and method for removing particulate contaminants from a fluid stream where the particulate contaminants have densities equal to or approximating the density of the carrier fluid.

A liquid/gas helical separator operates on a combination of centrifugal and gravitational forces. The separator includes a primary separator formed basically by an expansion chamber, a secondary separator formed basically by a helix for directing the flow, a tertiary separator which consists of a reservoir or gravitational-separation tank and of a transition region between the primary and secondary separators, which consists of at least two variable-pitch helixes whose inclination varies from an angle of 90.degree. to the angle of inclination of the constant-pitch helix of the secondary separator with the function of providing a gentler flow of the liquid phase at the transition between the first two separators.
