FIELD: production of centrifugal separators. ^ SUBSTANCE: the invention is intended for devices for purification of gasses from a dust and drips of a liquid by a centrifugal force. The centrifugal separator contains a body with placed in it on the driving shaft two the main centrifugal fans rigidly coupled and communicated among themselves by the internal space having a common butt wall and different heights and located one above another. Two additional centrifugal fans are attached to the top of the upper ventilator and to the low part of the lower ventilator. Inside of a body there is a diaphragm dividing it into two sections, the upper and the lower sections. At that the upper edge of the diaphragm is attached above the level of the common butt wall of the main centrifugal fans, and the lower edge is located below the level of the common butt wall. Above the diaphragm in the upper section of the body there is a tangentially mounted branch pipe for withdrawal of the purified gas, and under the diaphragm in the lower section of the body there is a tangentially mounted branch pipe for feeding of a dusty gas. A bonnet is attached to the butt of the lower main fan. The bins for collection of the dust are attached to the bottom of the body along its perimeter. The diaphragm may be made in the form of a funnel. Vanes of the main centrifugal fans are made in the form of a fragment of a spiral coiled in direction of the fan rotation. The technical result is an increased efficiency of purification of a gas from a dust and an improved capability to control the quality and the degree of the gas purification. ^ EFFECT: the invention ensures an increased efficiency of purification of a gas from a dust and an improved capability to control the quality and the degree of the gas purification. ^ 4 cl, 4 dwg |
