Problems solved by technology

If an inertial dust collector is used, the purification effect is poor; if a bag filter is used, the wind resistance is large, which will lead to a significant reduction in air volume, so that the cooling of the motor cannot be guaranteed; if a conventional centrifugal separator is used, it cannot be installed on a train locomotive due to its large size , and it is impossible to install a centrifugal blower before the separator

Embodiment Construction

[0014] The technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0015] The structure of the centrifugal dust separator provided by the present invention is as follows figure 1 As shown, it is composed of two concentrically arranged circular cylinders-an outer cylinder 1, an inner cylinder 2, and a cone-shaped dust collecting bucket 9 connected to the bottom of the outer cylinder 1. The upper part of the inner cylinder 2 is installed with a centrifuge The air inlet of the booster fan 4 and the booster fan impeller 3 is provided with an arc-shaped current collector 8. A streamlined deflector 6 is arranged at the air inlet at the bottom of the inner cylinder 2, and an annular guide vane 7 is arranged at the turning point of the inlet gas of the inner cylinder 2. Located at the center of the annular guide vane 7, a straight splitter 11 is fixed on the bottom end of the inner wall of the outer cylinder 1. A num...

Abstract

A centrifugal powder dust separator for electric locomotive and ship is composed of concentric internal and external cylinders, a conic dust-collecting hopper connected to lower end of external cylinder, a centrifugal boosting blower with arc airflow collecting unit at the upper part in internal cylinder, a stream-line guider at the bottom of internal bottom, and the exhaust pipes from inside of internal cylinder to outside of external cylinder.

Description

Technical field [0001] The invention relates to a centrifugal dust separator, which is used to reduce dust pollution to air and maintain a clean environment. It belongs to the field of fluid engineering technology. Background technique [0002] In order to create a clean environment, purify the air, reduce dust pollution to the air, and protect people's health, a device that can separate particulate dust in the air is needed. This kind of dust separator is required to have the characteristics of compact size, small pressure loss, and high dust removal efficiency. It is suitable for urban rail transit locomotives, ships, precision processing workshops and other occasions, and can meet the needs of a clean environment. For areas with heavy sandstorms and severe industrial pollution, it is especially important to use dust separators for efficient dust removal and air purification. [0003] At present, the conventional cyclone dust collector needs to be equipped with a high-pressure ...
