Active disc centrifugal separator

Abstract

The invention relates to an active disc centrifugal separator, comprising a stationary separation chamber housing, a separation rotor, and a driving chamber. The separation chamber housing comprises amixture inlet into which a gas-liquid mixture enters, a gas outlet for discharging purified gas, and a liquid outlet for discharging purified oil body. The separation rotor comprises a shaft, and a separating disc stacked on the shaft, and a separating disc base and a separating disc cover respectively arranged at the upper and lower ends of the separating disc, the shaft is supported by an upperbearing and a lower bearing respectively arranged at the upper and lower ends of the shaft, the upper bearing and lower bearing are respectively supported by an upper bearing seat and a lower bearingseat, and the upper bearing seat and the lower bearing seat are both arranged in the separation chamber housing; the driving chamber includes a pressurized liquid passage for pass of the pressurizedliquid, and the pressurized liquid enters a nozzle via the pressurized liquid passage. The active disc centrifugal separator has the advantages of high separation efficiency and stable separation.

Description

technical field [0001] The invention belongs to the technical field of disc centrifugal separator equipment, and in particular relates to an active disc centrifugal separator. Background technique [0002] At present, during the cylinder compression ignition process of the fuel engine, a small part of the high-pressure combustible gas mixture and combustion gas in the cylinder will enter the crankcase through the gap between the cylinder and the piston, forming a mixture of oil mist, air, water vapor and exhaust gas. The mixed aerosol, which gathers in the crankcase, makes the pressure in the crankcase too high, affects the engine working conditions, and damages the crankcase seal. In order to avoid and reduce the impact of the mixed gas in the crankcase on the engine operating conditions, it is necessary to separate the mixed gas from the crankcase for gas-liquid separation. [0003] Most of the current centrifugal separators have low separation efficiency. The separated o...

AI Technical Summary

Problems solved by technology

[0003] Most of the current centrifugal separators have low separation efficiency. The separated oil is not easy to be discharged quickly, and it is easy to cause the separation disc to be accumulated by dirt and affect the work of the separation disc. In order to further improve the working efficiency of the centrifugal separator, ensure that the centrifugal separator work stability, an active disc centrifugal separator is proposed
