[0002] Honeycomb dust filter unit is a highly efficient and advanced dust removal equipment, mainly used in dust and waste gas treatment in the industrial field. Its working principle is mainly based on the electric field effect, and the charged particles are collected on the electrode plate through the high-voltage electric field, thereby achieving the dust removal effect.

[0003] At present, in the existing technology, although honeycomb dust filter units are widely used in multiple industrial fields due to their efficient dust removal capabilities, single-level dust filter units may face the challenge of unsatisfactory filtering effects when dealing with high-concentration and complex dust, resulting in a certain amount of fine dust in the discharged air, which increases the cost of replacement and maintenance. In view of this, we propose a honeycomb dust filter unit. Utility Model Content
