Description

Technical Field

[0001] The utility model relates to the technical field of dust collector filtering equipment, in particular to a filtering mechanism of a cyclone separation dust collector. Background Art

[0002] A cyclone separator is a device used for separation of gas-solid systems or liquid-solid systems. Its working principle is to rely on the rotational motion caused by the tangential introduction of airflow to throw solid particles or liquid droplets with large inertial centrifugal force to the outer wall to separate. The main features of a cyclone separator are simple structure, great operational flexibility, high efficiency, convenient management and maintenance, and low price. It is used to capture dust with a diameter of 5 to 10 μm and is widely used in the pharmaceutical industry. It is particularly suitable for coarse dust particles, high dust concentration, high temperature and high pressure conditions. It is also often used as an internal separation device in a fluidized bed reactor, or as a pre-separator. It is a separation equipment widely used in industry.

[0003] However, the existing cyclone dust collector still fails to meet the emission standards after filtering larger particles in the air. The exhaust gas discharged from the top is still entrained with some dust. However, adding a separate secondary filtration process has the inconvenience of high cost and difficulty in adaptation.

[0004] In summary, the utility model solves the existing problems by designing a filtering mechanism of a cyclone separation dust collector. Utility Model Content
