Dynamic particle separator
First Claim
1. Dynamic particle separator for cyclone separation of sand from a gas stream in connection with petroleum related production of oil and gas, where the dynamic particle separator comprises a housing containing a cyclone tank that is equipped with an upper inlet opening for a gas stream and an upper and a lower outlet opening for export of gas and particles, respectively, from the cyclone tankwhereinthe cyclone tank is formed, at least in an internal area around the upper inlet opening, with an upper and downwardly directed conical shape that increases in diameter, andwhere an upper conical shape thereafter has a transition into an inverse, lower conical shape, that converges towards the lower outlet opening andthe housing comprises a lower chamber, in which the lower outlet opening ends up, and which is equipped with a collecting bucket with an open top for collection of separated particles, whereinthe collecting bucket is placed in a load cell to register an amount of collected particles in the collecting bucket, anda silting device is placed in the collecting bucket, where the silting device is connected to a pipe that runs out of the housing and where a silting process for export of particles through the pipe starts on a signal from the load cell;
- wherein the pipe is a double walled pipe that extends down into the bucket, where an outer, longitudinally running annular space of the pipe is connected to a water inlet for supply of water to a bucket and in which separated particles are exported through an inner part of the pipe and out via an outlet; and
wherein the silting process is arranged to be controlled externally by a control device, where the control device regulates the supply of water, a silting up of particles and export of particles and water.

Abstract
A dynamic particle separator is described for cyclone separation of sand from a gas stream in connection with petroleum related production of oil and gas, where the separator comprises a housing (14) containing as cyclone tank (4) that is equipped with an upper inlet opening (1) for the gas stream and an upper and a lower outlet opening (2,12) for export of gas and particles, respectively, from the tank (4). The cyclone tank (4) is formed, at least in an internal area around the inlet opening (1), with an upper and downwardly directed conical shape (4a) that increases in diameter, and where the upper conical shape (4a) thereafter has a transition into an inverse, lower conical shape (4b) that converges towards the lower outlet opening (12).
