Description

Technical Field

[0001] The utility model relates to the technical field of converter flues, in particular to an ultra-low emission dust collector for a converter process. Background Art

[0002] The converter flue, also known as the waste heat boiler, is a device for cooling flue gas and recovering steam. The cooling water that has been softened and deoxygenated absorbs the heat of the flue gas for its own evaporation, and uses the latent heat of water vaporization to carry away the heat of the cooling components, thereby reducing the temperature of the flue gas from 1400-1600℃ to 900-1000℃. When the flue gas is discharged, it needs to be processed by a dust collector, among which dust collection and noise reduction are the main treatment purposes of the dust collector for the flue gas.

[0003] Patent announcement number CN212610747U discloses a dust removal and noise reduction device for a converter flue, including a converter flue, an air intake pipe connected to the top of the converter flue, a motor bolted to the left side of the converter flue, an output shaft of the motor extending to the interior of the converter flue and clamped with a rotating rod, and a plurality of support rods welded to the surface of the rotating rod; the utility model, through the arrangement of a converter flue, an air intake pipe, a motor, a rotating rod, a support rod, a scraper, a fan, an electrostatic precipitator, a movable flue and a silencer structure, makes the dust removal and noise reduction device for the converter flue have the advantages of being able to reduce the noise of the converter flue and remove dust from the inside thereof, thereby solving the problem that the existing converter flue has high noise during production, which is easy to affect the working environment, and cannot be dusted internally, resulting in low transmission efficiency of the converter flue in subsequent production processes.

[0004] Although the prior art CN212610747U has many benefits during use, it still has the following problems: it lacks a shielding structure for the exhaust pipe, which causes external foreign matter to enter the exhaust pipe, causing blockage of the exhaust pipe and affecting the discharge smoothness of the smoke inside the exhaust pipe.

[0007] When using an ultra-low emission dust collector for a converter process in the technical solution, the flue gas is pressurized by an external fan and transported to the inside of the dust collector body for dust removal, and then transported to the flue and exhaust pipe for discharge.

[0010] Preferably, a smoke hood is installed on the outer wall of the upper end of the smoke exhaust pipe, and the size of the smoke hood is larger than that of the smoke exhaust pipe. The smoke hood shields the smoke exhaust pipe.

[0011] Preferably, an impeller is installed on the outer wall of the lower end of the rotating shaft, and the impeller is located at the lower end of the filter plate. The airflow drives the impeller and the rotating shaft to rotate in a circle.

[0012] Preferably, a scraper is fixed to the outer wall of the lower end of the connecting plate, and the scraper contacts the outer wall of the upper end of the filter plate. The scraper scrapes and cleans the outer wall of the filter plate.
