ABSTRACT:
The present invention provides an apparatus and method for the separation of solids entrained in fluid streams. The apparatus consists of a pipecross chamber which is divided into two regions by a perforated deflector/separator plate angularly disposed within the chamber. A shear jet is disposed perpendicular to the flow path and higher pressure fluid is thereby injected into the chamber to deflect and separate entrained solids. Embodiments are disclosed in which no deflector/separator plate is disposed within the chamber, separation being effected by the shear jet alone. In preferred embodiments the apparatus and method are used to protect a centrifugal pump impeller from damage by the solids. While conventional pipe joints and parts can be used, an alternate embodiment provides removable side plates and a removable deflector/separator plate for ease of installation and maintenance. Further enhancements include pipe elbow means having a jet in the direction of fluid flow through the elbow. A still further embodiment of the present invention includes a perforated pipe contained within a sealable tank which is by at least one pressurized jet connected to said perforated pipe within said sealable tank.
