Description

Technical Field

[0001] The utility model relates to the technical field of flue purging, in particular to a flue dust purging device. Background Art

[0002] After a long period of use, ash will accumulate inside the flue, and then form an obstacle during the combustion process, hindering the heat generated by the combustion from being transferred to the flue wall and the heat transfer medium, which will lead to a decrease in thermal efficiency, reduce energy utilization efficiency, increase energy consumption and operating costs, and at the same time, these ash deposits may cause corrosion, corrosion fatigue and mechanical wear of the equipment, and even cause equipment failure and damage. Ash deposits may also contain toxic substances such as heavy metals, further exacerbating the risk of environmental pollution. Therefore, it is very important to clean the ash in the flue regularly. Through regular flue cleaning and maintenance, the efficient operation of the equipment can be maintained, environmental pollution can be reduced, the risk of fire can be reduced, and the service life of the equipment can be extended.

[0003] The Chinese utility model patent currently announced is: CN214638801U, which discloses an online purge device for preventing dust accumulation in flue, including an air source main pipe and a purge part; the purge part includes multiple purge mechanisms, each of which includes a connecting pipe, a horizontal cross pipe, a tuning fork and multiple bristles, one end of the connecting pipe is connected to the air source main pipe, and the other end passes through the bottom wall of the horizontal flue, the other end of the connecting pipe is connected to the horizontal cross pipe, the extension direction of the horizontal cross pipe is perpendicular to the extension direction of the horizontal flue, the tube walls of the horizontal cross pipe are respectively connected to one end of multiple purge pipes, the direction of the other end of the purge pipe is the same as the extension direction of the horizontal flue, the tuning fork is fixedly arranged in the horizontal flue, the tuning fork is located at the other end of the purge pipe, and is used to receive the impact of the airflow, one end of the bristle is fixedly connected to the handle of the tuning fork, and the other end contacts the bottom wall of the horizontal flue.

[0004] Although this patent has the function of making the dust in the flue fall down by vibrating the tuning fork, and cleaning and collecting the inner wall of the flue, it does not have the function of reciprocatingly cleaning the inner wall of the flue to improve the cleaning efficiency. During use, the dust accumulated in the flue needs to be repeatedly rubbed to make the dust fall down, and then sent out of the flue by blowing and scraping. Only using the tuning fork to vibrate and shake off the dust may result in some dead corners of the inner wall not being cleaned properly, reducing the cleaning efficiency. Utility Model Content
