[0002] Flue gas dust removal device is a device used to purify particulate matter and pollutants in industrial flue gas, mainly used to protect the environment and human health. Flue gas dust removal device usually includes filters, dust collectors, spray devices and other components. Spray dust removal and purification devices are required for flue gas treatment.

[0003] After searching, a spray-type flue gas dust removal and purification device with announcement number CN219964369U includes a main body component, a diverter component and a spray component, the main body component includes a spray tower, the diverter component includes an air inlet pipe installed on one side of the spray tower, and an active deceleration plate installed on the top wall of the air inlet pipe. The utility model is equipped with a diverter plate. When the staff connects the air inlet pipe with the external pipeline, after the flue gas enters the inside of the air inlet pipe, the multiple active deceleration plates installed inside cooperate with the fixed deceleration plates to block the incoming flue gas, decelerate the flue gas, and prevent the incoming flue gas from being rushed to one side due to excessive speed. When the decelerated flue gas enters the inside of the spray tower, the multiple diverter plates at different angles installed inside the spray tower can provide flow guidance for the incoming flue gas to different areas, prevent the uneven use of the filling layer due to the concentration of flue gas on one side, reduce the cleaning and purification effect, and reduce the service life of the filling layer, which brings convenience to the staff.

[0004] Based on the above patent, by installing a diverter plate, when the staff connects the air intake pipe with the external pipeline, after the smoke enters the air intake pipe, the multiple movable deceleration plates installed inside cooperate with the fixed deceleration plates to block the incoming smoke, slow down the smoke, and prevent the incoming smoke from being rushed to one side due to its too fast speed. When the smoke after deceleration enters the spray tower, the multiple diverter plates installed at different angles inside the spray tower can provide flow guidance for the incoming smoke to different areas, prevent the uneven use of the filling layer due to the concentration of smoke on one side, reduce the cleaning and purification effect, and reduce the service life of the filling layer, which brings convenience to the staff. However, when the filter screen filters the dust, all the dust will fall onto the filter screen for collection, and the filter screen of the device is fixed on the device, which is troublesome to disassemble and clean, thereby reducing the efficiency of cleaning and installation.
