Technical Field

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

[0002] In industrial production, a large amount of dust-laden flue gas is often generated. If these dust-laden flue gases are directly discharged, they will seriously affect human health and cause damage to the environment. Therefore, these dust-laden flue gases are guided into a treatment device for treatment before being discharged. Common dust-laden flue gas treatment devices include bag filters. The bag filters commonly found on the market currently use woven filter cloth or non-woven felt, and utilize the filtering effect of the fiber fabric to filter the dust-laden gas to purify the gas. Filtering only through the dust bag will, on the one hand, cause a heavy filtering burden on the dust bag, reducing its service life. On the other hand, the high concentration of sulfur oxides and nitrogen oxides in the flue gas can easily corrode the dust bag, shortening its service life.

[0003] Therefore, we propose a dust-containing flue gas treatment device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that some current dust-containing flue gas treatment devices only filter through dust bags, which, on the one hand, causes a heavy filtering burden on the dust bags and reduces their service life; on the other hand, the higher concentrations of sulfur oxides and nitrogen oxides in the flue gas easily corrode the dust bags and shorten the service life of the dust bags.

[0007] The mounting plate is arranged near the top of the device box, and a plurality of dust removal bags are arranged on the mounting plate.

[0008] Furthermore, the stirring assembly includes a rotating shaft, which passes through the bottom of the diverter box, one end of the rotating shaft is located in the air intake pipe, and the other end of the rotating shaft is located outside the diverter box, a spiral blade is provided near the top of the rotating shaft surface, the spiral blade is located in the air intake pipe, and a plurality of evenly distributed stirring rods are provided near the bottom of the rotating shaft surface, a sealed bearing is provided at the position where the diverter box contacts the rotating shaft, and the sealed bearing is adapted to the rotating shaft.

[0011] Furthermore, a water level detector is provided in the device box.

[0012] Furthermore, a water inlet pipe is connected to the surface of the device box, and a solenoid valve is installed on the water inlet pipe.

[0013] Furthermore, the mounting plate divides the interior of the device box into a processing chamber and a clean air chamber, an activated carbon filter plate is provided in the clean air chamber, an air outlet pipe connected to the clean air chamber is provided on the outside of the device box, and the air outlet pipe is located above the activated carbon filter plate.
