AI Technical Summary
Technical Problem
In existing flue gas denitrification devices, it is difficult to effectively separate gas and ammonia water in a limited space, which makes it difficult to discharge gas and reduces the exhaust and treatment efficiency of the equipment.
Method used
The system employs a reflux-type gas emission auxiliary component and a diversion effect maintenance component. Through multiple ammonia water refluxes and through-hole dispersion, the gas is effectively discharged. The through-hole is self-cleaned by the through block to avoid blockage.
Benefits of technology
It improves the exhaust and treatment efficiency of flue gas denitrification equipment, prevents blockage of through holes, ensures smooth flow of ammonia water, and enhances the overall treatment effect.

Abstract
This invention belongs to the field of flue gas denitrification technology, specifically a denitrification device for an aluminum melting furnace. It includes a base, a treatment tank fixedly connected to one side of the upper end of the base, multiple long pipes arranged horizontally and fixedly connected to the upper side of the inner cavity of the treatment tank, and multiple nozzles installed on one side of each long pipe. A filter box is fixedly connected to one side of the upper end of the base, and a filter screen is fixedly connected to one side of the inner cavity of the filter box. An exhaust port is provided on one side of the upper end of the treatment tank, and an exhaust pipe is provided on one side of the inner cavity of the treatment tank. A reflux-type gas emission auxiliary component is also provided on the treatment tank. This invention utilizes the reflux-type gas emission auxiliary component to repeatedly reflux ammonia water into the distribution cylinder, where it is fully dispersed as it flows out through the through-holes. This makes it easier to discharge the gas entrained by the ammonia water, thereby improving the overall exhaust and treatment efficiency of the equipment.
