AI Technical Summary

Technical Problem

Existing filter cleaning technologies suffer from incomplete cleaning, easy generation of secondary pollution, and high energy consumption. In particular, they cannot systematically prevent the secondary diffusion and contamination of pollutants stripped off during the cleaning process.

Method used

The system adopts a closed system, combining a sealed dust removal mechanism with a high-efficiency dust filtration mechanism. The high-pressure concentrated airflow generated by the tornado blade and the rotational friction driven by the slewing bearing achieve efficient stripping of the filter element. The stripped dust is then directionally transported to a multi-stage dust filtration unit for settling and filtration through a flow guiding structure and negative pressure suction to prevent secondary diffusion.

Benefits of technology

It achieves thorough cleaning of the filter element, eliminates secondary pollution, improves cleaning efficiency and environmental friendliness, and enhances the adaptability and resource utilization of the equipment.

Abstract

This application discloses a filter element cleaning device, which includes a dust removal mechanism for cleaning the filter element and a dust filtration mechanism for filtering dust generated during the cleaning process. The dust removal mechanism and the dust filtration mechanism are connected. By integrating a rotating component that drives the filter element to rotate, a blowing component that generates a high-pressure concentrated airflow, and a mechanical impact component into a sealed component, a three-dimensional cleaning unit combining pneumatic flushing and mechanical vibration is formed. Simultaneously, through a guide section with a specific spatial configuration and a multi-stage guide component, a tiered physical purification flow channel of "inertial sedimentation - accelerated washing - gas-liquid separation" is constructed, and a forced directional airflow is formed by a negative pressure fan. This application achieves a closed-loop treatment of the entire process from "closed stripping, directional transport to efficient collection" of pollutants, significantly improving the thoroughness of cleaning while fundamentally preventing secondary dust diffusion during the cleaning process.
