Most of these high-temperature gases are produced by using coal or heavy oil as fuel, and a large amount of dust-containing high-temperature gases are generated during the combustion process. These high-temperature gases need to be treated before being emitted.

[0003] For example, Chinese Patent CN100560182C discloses a high-temperature flue gas dust removal device for filtering solid impurities, belonging to the field of dust removal equipment technology. The technical problem to be solved by the ceramic filter dust collector of the present invention is to provide a dust collector that is resistant to high temperature and corrosion, and is fast and efficient. Its main technical solution is as follows: The ceramic filter dust collector is mainly composed of a shell, a ceramic filter device, a pulse back-flushing system and a dust removal system. The structure of the ceramic filter device is as follows: the tube sheet is fixed on the inner wall of the shell, and the tube sheet is provided with tube sheet holes. The lower end of the ceramic filter element extends into the shell through the tube sheet holes and is fixed to the shell by a lower fixing device. The upper end of the ceramic filter element is connected to the tube sheet and is fixed to the tube sheet by an upper fixing device.

[0004] Although the above technical solutions have solved the corresponding technical problems, they still have the following drawbacks:

[0006] The purpose of this invention is to provide a corrosion-resistant and high-temperature-resistant flue gas dust removal device. The gas to be treated is introduced into the dust removal housing through the inlet pipe, filtered by the dust collector bag, and then discharged through the outlet. When there is a lot of dust adsorbed on the surface of the dust collector bag, the servo motor is turned on. The servo motor drives the mounting plate at the bottom of the drive rod to rotate, which in turn drives the striking ball to rotate. This allows the surface of the dust collector bag to be tapped, thereby shaking off the dust and improving the dust removal efficiency.

The other end of the L-shaped limiting rod is fixedly connected to the bottom of the end cover.

[0017] This utility model has at least the following beneficial effects:

[0018] The corrosion-resistant and high-temperature-resistant flue gas dust removal equipment provided by this utility model introduces the gas to be treated into the dust removal housing through the inlet pipe, and after being filtered by the dust removal bag, it is discharged through the outlet.
