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 solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] The structure of the centrifugal dust separator provided by the invention is as follows: figure 1 As shown, it consists of two concentrically arranged circular cylinders inside and outside—the outer cylinder 1, the inner cylinder 2, and the conical 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 centrifugal The booster fan 4 and the air inlet of the booster fan impeller 3 are provided with an arc collector 8 . A streamlined deflector 6 is provided at the air inlet at the bottom of the inner cylinder 2, and an annular guide vane 7 is installed at the gas inlet turning 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 . ...

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 for reducing dust pollution to the air and maintaining a clean environment. It belongs to the technical field of fluid engineering. Background technique [0002] In order to create a clean environment, purify the air, reduce the pollution of dust to the air, and protect people's health, a device that can separate the 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, etc., and can meet the needs of clean environments. For areas with large wind and sand, and for places with serious industrial pollution, it is especially important to use dust separators for efficient dust removal and air purification. [0003] The current conventional cyclone dust collector needs to inst...
