Flue gas filtering device

Abstract

The invention discloses a flue gas filtering device which comprises a flue gas pipe, a mounting frame, amounting plate and a linkage assembly; the mounting frame is mounted on the inner wall of the flue gas pipe, a rotating disc is rotationally mounted on the outer side of the mounting frame, mounting blocks are mounted on the circumferential side of the rotating disc, and scrapers are mounted on the mounting blocks; the mounting plate is mounted on the inner wall of the flue gas pipe, and a motor is mounted on the mounting plate; and the linkage assembly is installed on the mounting frame and acts on the rotating disc, and the motor is connected with the linkage assembly. According to the flue gas treatment device, when flue gas circulates in the flue gas pipe and an output shaft of the motor rotates, the linkage assembly drives the rotating disc to rotate, the scraping plate rotates in the axis direction of the rotating disc, and when the scraping plate rotates, one end of the scraping plate makes contact with the inner wall of the flue gas pipe, dust, particles and the like on the inner wall of the flue gas pipe are scraped off, and caking on the inner wall of the flue gas pipe is prevented; and compared with an existing device, the device can prevent the inner wall of the flue gas pipe from caking and avoiding blockage, the service life of the filtering device is greatly prolonged, the overall structural design is ingenious, and the device is suitable for industrial popularization and application.

Description

technical field [0001] The invention belongs to the technical field of flue gas filtering, and in particular relates to a flue gas filtering device. Background technique [0002] For dust-laden flue gas, during long-term work, part of the dust in the flue gas will adhere to the inner wall of the flue gas pipe. When a certain amount of dust accumulates on the inner wall of the flue gas pipe, it will form agglomerates. When the flue gas passes through the flue gas pipe, Part of the dust and particles will adhere to the agglomerates, making the agglomerates bigger and bigger. When the agglomerates have a certain size, they will fall by themselves and circulate with the flue gas, and finally fall on the filter bag, causing the filter bag to be blocked . The existing filter bags need to be replaced or cleaned frequently, which is inconvenient to use. For this reason, the present application provides a smoke filter device to solve the deficiencies of the prior art. Contents of...
