A high-efficiency cyclone dust collector with built-in guide vanes

Abstract

Aiming at the shortcomings of the existing cyclone dust collector, the present invention proposes a high-efficiency cyclone dust collector with built-in guide vanes. The device mainly includes a cylinder body 1, a cone body 2, an air inlet 3, an exhaust pipe 4, an exhaust Port 5, ash discharge port 6, guide vane 7, ring body 8. The present invention combines the working characteristics of the cyclone dust collector itself, by installing guide vanes along the rotation direction of the air flow at the interface of the inner and outer swirling airflow at the lower end of the exhaust pipe in the cyclone dust collector or near it, to further reduce the particles in the inner swirling airflow. Separation, thereby improving the dust removal efficiency of the cyclone dust collector. The device has the advantages of simple structure, convenient installation, high efficiency and energy saving.

Description

technical field [0001] The invention relates to the field of cyclone dust collectors, in particular to a device for improving the dust removal efficiency of cyclone dust collectors. Background technique [0002] In the process of production and life, human beings need a clean air environment. However, many production processes (such as cement, non-ferrous metal smelting, casting, etc.) will emit a large amount of particulate matter. If it is discharged into the atmosphere randomly, it will pollute the atmosphere and endanger human health. In addition, since the 21st century, the problem of environmental pollution has intensified, and air pollution has become one of the problems to be solved urgently, especially the pollution and prevention of particulate matter (commonly known as PM2.5) in dust has become a hot issue of concern all over the world. Therefore, the dust-laden waste gas must be purified before it is allowed to be discharged into the atmosphere when it reaches t...

AI Technical Summary

Problems solved by technology

[0004] Cyclone dust collectors are generally used to collect particles above 5-15um. The disadvantage is that they cannot collect particles with a particle size of less than 5um, which limits the further improvement of their dust removal efficiency. This is mainly because: In traditional cyclone dust collectors, the cutting Most of the airflow entering the cyclone dust collector from the air inlet first flows along the wall of the cyclone in a spiral shape downwards towards the cone, forming an outer vortex
