Centrifugal separator

Abstract

A centrifugal separator for treating polluted gas is composed of a central rotary shaft, an external casing, and several settling tubes, which are arranged in axial symmertrical mode relative to central rotary shaft to form a circular table shape and along the mother lines to become inclinded, and are revolving around said central rotary shaft. Said settling tube has a smooth settling inner surface at its far end. Its advantages are high separation efficiency and gas flow, and self-cleaning.

Description

technical field [0001] The invention belongs to the field of industrial environmental protection machinery and equipment, in particular to a centrifugal separator utilizing inertial centrifugal force in industrial production. Background technique [0002] In the prior art, the principle of the separator that uses centrifugal force to remove dust is mainly: use the rotating blades to rotate the dusty gas at high speed, and the dusty gas leaves the blades to form a high-speed whirlwind, and then use the centrifugal force generated by the rotation in a small space Make the dust particles settle in the fixed dust structure. There are several problems in this device: first, the velocity of the gas in the space from its center to the fixed settling wall changes greatly to 0, and the sudden change of the velocity gradient reduces the separation effect; The sudden reduction or disappearance of the centrifugal force makes it quickly dragged up by the high-swirl gas; finally, due to ...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to solve the problems of low separation efficiency, complex structure and high power consumption of the existing inertial centrifugal dust removal device. The purpose of the present invention is to provide an effective centrifugal separator to overcome The above defects in the prior art, the present invention relies on the following technical solutions to achieve, a centrifugal separator, including a central rotating shaft and an outer casing, the centrifugal separator outer casing is provided with a rotationally symmetrical arrangement with respect to the central rotating shaft and Settling tubes that can rotate synchronously around the rotating shaft. The settling tubes are arranged around the rotating shaft in the shape of a conical shell and arranged along the side of the busbar. The wall surface of the settling tube on the side far from the rotating shaft is a smooth settling surface, which can be a smooth curved surface. Or plane, the radius of rotation of the settling surface on the outlet end face of the shaft is greater than the radius of rotation on the inlet end face
