AI Technical Summary

Technical Problem

Existing exhaust gas filtration devices are prone to clogging and difficult to clean under high dust concentrations. Existing cleaning methods are complex, energy-intensive, and the filter media is easily damaged and not thoroughly cleaned, especially stubborn particles on the inner wall of the filter bag are difficult to remove.

Method used

The system employs a transmission structure to drive the filter elements to rotate for filtration and reverse rotation for cleaning. It combines inertial separation and reverse airflow purging, and utilizes a one-way valve and fan blades to achieve automated cleaning, avoiding mechanical contact. A baffle plate is also installed to guide the particles.

Benefits of technology

It achieves efficient and uniform filtration, reduces equipment complexity and cleaning energy consumption, extends filter media life, significantly improves cleaning effect, and avoids secondary pollution.

Abstract

本发明属于废气处理技术领域,具体公开了一种废气过滤器及其使用方法,包括收集壳和过滤结构,过滤结构包括等间距贯穿收集壳上的过滤件,收集壳的一侧固定有排气结构,过滤件的排气端与排气结构连通,排气结构上连接有驱动过滤件旋转的传动结构,当收集壳的内部进入废气时,传动结构带动过滤件在收集壳的内部旋转,进而实现废气中的颗粒物均匀接触过滤件,使废气快速贯穿过滤件进入到排气结构内,排气结构上连接有单向阀,传动结构上连接有扇叶。该发明通过一套传动结构同时实现过滤与清灰,采用旋转惯性力与反向气流协同作用进行无接触式深度清洁,既避免了滤材机械损伤、防止了颗粒二次飞扬,又大幅降低了能耗和结构复杂度。
