Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and in particular relates to waste gas treatment equipment for environmental protection. Background Art

[0002] Waste gas emitted from industrial production often has harmful effects on the environment and human health. Purification measures should be taken before it is discharged into the atmosphere to make it meet the requirements of waste gas emission standards. This process is called waste gas purification treatment.

[0003] The existing patent with announcement number CN214764401U relates to an exhaust gas spray tower equipment for exhaust gas treatment, including a tower body, support columns are slidably arranged on both sides of the top of the tower body, the top of the support columns is fixedly connected to a placement plate, a water pump is fixedly installed on the placement plate, and the water outlet of the water pump is connected to a delivery pipe; the other end of the delivery pipe rotates in turn to pass through the placement plate and the tower body and extends to the interior of the tower body, and one end of the delivery pipe located in the tower body is connected to a water outlet tray; a connecting column is fixedly arranged at the bottom of the placement plate, and a first gear is fixedly arranged at the bottom of the connecting column; a stepping motor is fixedly arranged on the top of the tower body, and a second gear is fixedly arranged on the output shaft of the stepping motor, and the second gear is meshed with the first gear.

[0004] The above scheme realizes the rotation of the water outlet disc by driving the second gear to rotate through the output shaft of the stepper motor, and the rotation of the second gear drives the first gear to rotate. The rotation of the first gear drives the placement plate to rotate, and the rotation of the placement plate drives the water pump to rotate. The water pump drives the water outlet disc to rotate through the delivery pipe, so that the water outlet disc and the nozzle can rotate to fully spray the exhaust gas in the tower body. The whole process requires the use of a stepper motor as the driving source for the rotation of the water outlet disc. Long-term operation will cause the stepper motor to heat up and be damaged, resulting in a waste of resources and increased use costs. Utility Model Content
