It uses the principle of water film desulfurization and dust removal. It is also called granite water film desulfurization dust collector, or granite water film desulfurization dust collector. When the desulfurization tower is operating, the external air needs to be transported into the tower, and then air oxidation is carried out at the same time.

[0003] However, in actual use, the air is often not sufficiently mixed with the gas to be treated. Therefore, it is necessary to improve the existing structure, improve the mixing efficiency of air and flue gas, and effectively increase the reaction speed. Moreover, when treating the gas, it is also necessary to keep it inside the device long enough for a sufficient mixing reaction to occur. Utility Model Content

[0009] Preferably, one end of the input pipe is inclined toward the top and is rotatably connected to the inside of the rotating pipe. The inner top of the rotating pipe is closed, and a plurality of nozzles are arranged around the side wall of the rotating pipe close to the inside of the tower body.

[0010] Preferably, the top of the tower body is connected and fixed to the bottom of the baffle through a plurality of support columns, and the bottom edge of the baffle is inclined toward the top. The top of the baffle is fixedly connected with a connecting ring, and the connecting ring is in a circular ring shape.

[0015] Starting the driving motor causes the through rod to rotate, which can drive the fan at the top to rotate, and the fan drives the gas to be transported to the inside of the conduit through the tapered hole and the funnel, and then transported to the bottom through the conduit. At the same time, the rotation of the through rod causes the driving gear to rotate, and the driving gear drives the driven gear to rotate, which can drive the rotating tube to rotate, causing the nozzle to rotate.
