CENTRIFUGAL GAS-AND-LIQUID SEPARATOR FILTER Russian patent published in 2007 - IPC B01D45/12 

FIELD: equipment for cleaning gases and liquids from mechanical admixtures; gas, oil, power-generating and other industries.

SUBSTANCE: proposed filter has vertical housing with taper cover and bottom, tangential mixture inlet, axial tube, shielding taper plates, cleaned gas and liquid outlet branch pipes with respective valve units shutting-off flow of liquid or gas. Taper bottom is provided with unit for separation of solid fraction which is located underneath. Axial tube is made in form of stack of perforated branch pipes whose lower part is telescopically inserted into upper part of other branch pipe at limited turn. Lower perforated branch pipe telescopically enters the cleaned liquid outlet branch pipe which is bent sideways for recirculation of liquid. Upper end of each perforated branch pipe but for upper one is provided with taper plates. Upper perforated branch pipe is rigidly connected with cleaned gas outlet branch pipe which is hermetically fitted in taper cover for rotation and locking in extreme positions. It ensures recirculation of gas. Holes of perforated branch pipes are closed on the outside with filters whose throughput may be changed at turn of perforated branch pipes relative to each other. These filters are made in form of cylindrical screens inserted coaxially and hermetically one in other and may be turned relative to each other. Upper end of one of cylindrical screens is hermetically connected to perforated branch pipe above holes and lower end of other cylindrical screen is hermetically connected to upper edge of other perforated branch pipe or cleaned liquid outlet branch pipe; perforated branch pipe with first cylindrical screen is inserted in this branch pipe.

EFFECT: improved quality of cleaning gas and liquid.
