AI Technical Summary
Technical Problem
The existing boiler filter structure is an integrated design, which makes it difficult to install and disassemble freely, resulting in inconvenience for replacement and cleaning, and poor filtration effect.
Method used
It adopts a graded filtration structure, including an air inlet box, a first filter frame, and a second filter frame, which are respectively equipped with coarse and fine filter plates. The filter frames are moved by a motor-driven lead screw, which facilitates cleaning. Combined with activated carbon plates, it purifies the flue gas.
Benefits of technology
It achieves graded filtration of flue gas, improves filtration efficiency, and simplifies the cleaning process through convenient structural design, enhancing the ease of equipment maintenance.

Abstract
The utility model belongs to the technical field of boiler dust removal, and particularly relates to a graded filtering structure for boiler dust removal, which comprises a base, an air inlet box is arranged at the center of the top of the base, an air inlet is arranged at the top of the air inlet box, a guide ring is fixedly mounted in the air inlet box, and first filtering frames are respectively arranged on two sides of the air inlet box. Two groups of first filtering frames are arranged in the air inlet box, second filtering frames are arranged on the sides, deviating from each other, of the two groups of first filtering frames respectively, exhaust ports are formed in the sides, deviating from each other, of the two groups of second filtering frames, and a connecting frame is fixedly mounted at the bottom of the air inlet box. Flue gas is conveyed into a first filter frame under the action of an induced draft fan, large dust particles in the flue gas are filtered through a coarse filter frame, small dust particles in the flue gas are filtered through a fine filter frame, the flue gas is conveyed into a second filter frame, and the flue gas is purified through an activated carbon plate; grading treatment is achieved according to the size of dust particles, and the smoke filtering effect is improved.
