Claims

1. An automatic control device for oxidation air volume in a desulfurization system, characterized in that: The system includes a housing, inside which a mounting plate is fixedly installed. An air inlet pipe and an air outlet pipe are fixedly installed on the upper part of the mounting plate. The opposite ends of the air inlet pipe and the air outlet pipe are connected by a connecting plate. The other end of the air inlet pipe extends to the outside of the housing and connects to the output end of an oxidation blower. The other end of the air outlet pipe extends to the outside of the housing and connects to a desulfurization system. A through hole is formed in the center of the connecting plate, and symmetrical connecting rods are arranged on both sides of the connecting plate near the through hole, respectively connecting to the air inlet pipe and the air outlet pipe. An inner limiting ring is provided for rotational engagement with the inner circumferential wall, and an outer limiting ring is provided on the outer side of each inner limiting ring for rotational engagement with the outer circumferential wall of the air inlet pipe and the air outlet pipe; a ventilation baffle is fixedly provided on the inner circumferential wall of the air inlet pipe near the inner limiting ring, and multiple fan-shaped ventilation openings are evenly provided on the ventilation baffle along the circumferential direction; multiple baffles are evenly provided on the end of the inner limiting ring corresponding to the air inlet pipe along the circumferential direction, each of which is adapted to each ventilation opening; a drive motor for driving the connecting plate to rotate is provided at the bottom of the mounting plate.

2. The apparatus for automatically controlling the amount of oxidation air for a desulfurization system according to claim 1, characterized by: The air inlet pipe and the air outlet pipe are respectively fixed to the mounting plate by fixing rings.

3. The apparatus for automatically controlling the amount of oxidation air for a desulfurization system according to claim 1, wherein: The connecting plate is provided with a sealing ring between the corresponding inner and outer limiting rings, and each sealing ring abuts against the end of the air inlet pipe or the air outlet pipe.

4. The apparatus for automatically controlling the amount of oxidation air for a desulfurization system according to claim 1, characterized by: The mounting plate has a clearance groove at a position corresponding to the connecting plate, and the lower end of the connecting plate passes through the clearance groove and extends to the bottom of the mounting plate; a transmission gear ring is provided on the outer peripheral wall of the connecting plate, and a transmission gear adapted to the transmission gear ring is provided on the drive shaft of the drive motor.

5. The apparatus for automatically controlling the amount of oxidation air for a desulfurization system according to claim 1, characterized by: It also includes a sulfite detector and a controller located at the bottom of the mounting plate. The sulfite detector is electrically connected to a sulfite measuring electrode, which is arranged in the desulfurization slurry of the desulfurization system. The sulfite detector and the drive motor are both electrically connected to the controller.
