摘要

Cleaning system for removing debris from a fluid and metal flow of a fluid recirculante a well bore and method of removing metallic debris from a flow of fluid.A system and a method of cleaning for removing metallic debris flow of a fluid, such as a flow of drilling mud stock, employ one or more magnetic units positioned in the route of the fluid, to collect metallic particles in the flow. The magnetic unit has a number of magnet in a removable sleeve not magnetic.When the core is removed, the metal particles attracted are falling with the sleeve under the action of gravity, to facilitate the collection and disposal of them. A baffle is positioned in the fluid amount of each magnetic unit, protecting the magnetic unit from direct impact by the strong flow.The magnetic units are left pivotar from side to side and adjust their positions in the flow.
