Regeneration filter device for fine particles

Abstract

The invention provides a regeneration filter device for fine particles. The device is characterized in that a filter device body includes at least two layers of filter boxes; multiple clamping ports with the same gaps are formed in the upper ends of two opposite side walls of the filter boxes; filter modules are matched with holding spaces divided in the filter boxes, and are fixedly clamped in the filter boxes through the clamping ports; metal fiber felts for filtering are arranged in the filter modules in a triangular array form; absorption heat conducting layers are arranged between every two layers of filter boxes, and are carbon fiber felts; and the absorption heat conducting layers are connected with external heating equipment. The filter device has multiple layers of filter boxes; the layer number can be set according to actual demands to satisfy the filter demands under various conditions; in addition, large particles in tail gas can be effectively absorbed according to an arranging form of the metal fiber felts; one part of gasifiable impurities are decomposed through a heating mode to prevent blockage of filter holes; and the filter device has such advantages as simple structure and high practicability.

Description

technical field [0001] The invention relates to the technical field of filter equipment, in particular to a regenerative filter device for fine particles. Background technique [0002] As we all know, the pollutants emitted by motor vehicle exhaust contain a large amount of particulate matter. With the improvement of living standards, the use of motor vehicles has increased rapidly, causing serious pollution to the air in cities. How to effectively filter out these exhaust particles is an important link in the process of automobile exhaust treatment. [0003] In the prior art, there are many filters that can filter particulate matter, but the filter itself has no regeneration function. After the filter has been used for a long time, a large amount of filtered particulate matter will adhere to the filter screen of the filter, resulting in filter holes on the filter screen. If the filter becomes clogged, resulting in reduced engine performance or malfunction, other methods mu...
